BARRIER-FREE DESIGN GUIDELINES

LEGAL PROVISIONS IN MALAYSIA RELATED TO BARRIER FREE DESIGN


Uniform Building By-Laws 1984

The Uniform Building By-Laws 1984 was amended in 1990 to include the provision of by-law 34A which requires that all buildings that can be visited by the public be provided with facilities for disabled people:

a. The First Section requires that access be provided to enable the disabled to enter, exit and move about within a building and the design of the access must be suitable for the disabled.
-
b. The Second Section stipulates that the specifications of the facilities for the disabled should be in accordance with the Malaysian Standards MS 1184 and MS 1183.
-
c. The Third, Fourth and Fifth Sections stipulates that local authorities should ensure that building plans submitted must comply with the Malaysian Standards, i.e. to include facilities for the disabled in the building and any alterations made to the building.
-
d. The Sixth Section lists the buildings that are required to adhere to this by-law. These include office buildings, terminals, car parks, and public buildings such as hospitals, government buildings, restaurants, cinemas, sports complexes, schools, hostels, hotels and others.
-
e. On the whole, in the legal context, facilities for the disabled have been included in the amendment to the Uniform Building By-Laws (1984) in 1990 by adding provision 34A. All Local Authorities are required to enforce these laws and ensure that the facilities are provided according to Malaysian Standards MS 1184 and MS 1331.


SIRIM Code of Practice

1) Code of Practice for Access for the Disabled to Public Buildings (MS1184)

This code of practice, issued by SIRIM in 1991, represents the Malaysian Standard for the provision and design of special facilities within a building so that they can be used easily an safely by disabled people.

The main subjects included in this code are specifications of the features for the facilities such as the size, measurement, type, material and design which are suitable and safe to be used by the disabled. These facilities include ramps, handrails, stairs, toilets, bars, signs and symbols.

This code also specifies the types of buildings that are required to provide these facilities:

a. Hospitals, clinics, welfare centres, mosques/suraus;

b. Shop houses, supermarkets, administrative centres, offices, banks and post offices;

c. Restaurants, cinemas, conference halls, community centres, swimming pools, sports

complexes and recreational buildings;

d. Government/public buildings;

e. Schools, colleges, universities, zoos, museums, galleries, libraries and science and cultural

buildings; and

f. Hostels, hotels and residential buildings except private houses.


2) Code of Practice for Access for Disabled People Outside Buildings (M8 1331) 1993
-
This code of practice, issued by SIRIM in 1993, represented the Malaysian Standard for the provision and design of special facilities outside of buildings so that they can be accessed and used the disabled.
Among the facilities are pavements, lighting, ramps, stairs, handrails, street furniture, pedestrian walkways, special seating, underpasses, footbridges, pedestrian crossings, traffic islands, special parking areas, bus stops, signages and symbols. This code applies to all types of buildings including place of work and public buildings - Private residences are excluded.

3) Code of Practice for the Means of Escape for the Disabled (MS 1183)1990
-
This code of practice provides guidelines to building designers and contractors for works on new buildings or renovation of existing buildings. It also outlines the steps that need to be taken involving the safety of the disabled in the event of a fire. Among the fire prevention and safety provisions for the disabled include stairs, spaces, exits, emergency/fire lifts, emergency phones, stairs and lifts specifically for wheelchair users.
-
As with code MS 1184:1991, this code has also been gazetted in the Uniform Building By-Laws, 1984 with the addition of provision 34A which requires that all buildings (except private residences) that can be visited by the public, are provided with fire safety facilities for the disabled.

WHAT IS DISABLED MEAN IN LANDSCAPE ARCHITECTURE??


Introduction

The Malaysian Social Welfare Department uses the following definitions:
- Disabled person as anyone who is incapable of obtaining for himself all or part of the normal needs of an individual and / or cannot participate fully in the life of the community due to abnormality since birth or in later life.

(Source: Town And Country Planning Peninsular Malaysia, 2002)

The World Health Organization (WHO) uses the following definitions:

1) Impairment

Any loss or abnormality of psychological, physiological or anatomical structure or function. An impairment can be temporary or permanents. This includes the existence or occurrence of an anomaly, defect or loss in a limb, organ, tissue or other structure of the body, including the systems of mental function.

2) Disability

Any restriction or lack (resulting from impairment) of ability to perform an activity in the manner or within the range considered normal for human being. A disability may be temporary or permanent, reversible or irreversible and progressive or regressive.

3) Handicap

A disadvantage for an individual, resulting from an impairment or disability, the limits or prevents the fulfillment of a role that is normal (depending on age, sex and social and cultural factors) for that individual.

(Source: Holmes - Siedle. J,, 1996)

For the purpose of this study, it has been necessary to define particular handicaps, impairments and restrictive devices so that they may be related to individual design elements. The terminology used below, with the exception of “temporary impairments”, is generally accepted and used in literature dealing with the handicapped.

1) Wheelchair

A wheel chair is a chair on wheels normally propelled by the occupant by means of handrims attached to the two side wheels. Wheelchairs may also be motorized or propelled by an attendant (Refer to Figure 1).
-



Figure 1 : Wheelchair

2) Crutch

A crutch is a staff with crosspieces at the top to support the person in walking. The point of support may be under the shoulder, upper arm or forearm. For each crutch, a person support is provided at hand level (Refer to Figure 2 ).
-



Figure 2 : Persons Who Using A Crutches



3) Cane

A cane or walking stick is a short staff either straight or curved at the upper end, used to provide some support at hand level in walking (Refer to Figure 3).
-



Figure 3 : Person Who Using A Cane
-
4) Walker

A walker is a four-legged stand which provided support for the user. It is moved by lifting or by wheeling on casters.

5) Brace

A brace is defined as any kind of supportive device for the arms, hands, legs, feet, back, neck or head, exclusive of temporary casts, slings, bandages, trusses, belts or crutches (Refer to Figure 4).
-



Figure 4 : Persons Who Using A Brace
(Source:Robinette.G.O., 1985)


-
6) Artificial Limb
-
An artificial limb is device to replace a missing leg, hand or foot. It does not necessarily have moving parts. A device employed only for lengthening a leg where the whole leg or foot is present is not included in this definition.

7) Special Shoes
-
Footwear specifically designed as pediatric aids to be used in assisting people in walking.
(Source : Robinette.G.O., 1985)
8) Ramps
-
Ramps are an essential method for assisting wheeled traffic to cope with changes in level that are traditionally overcome by using steps. Wheeled traffic can include wheelchairs, parents with prams, trolleys and other vehicles. Ramps are not replacement for stairs and steps, but are needed as and additional method for dealing with change in level (Refer to Figure 5).
-



Figure 5 : Ramps

9) Pathways
-
The ideal pathway is well illuminated, even, firm and well drained, presenting a non-slip surface in both wet and dry conditions. Sudden or irregular changes in gradient and gaps more than 10mm wide in the surface of the path should be avoided (Refer to Figure 6 ).

Basic Guideline For Consideration in Physical Planning And Design.

1. Accessibility - The built environment shall be designed so that it is accessibility for all people, including those with disabilities and elderly persons.

2. Access or Accessible - This means that people with disabilities can, without assistance, approach, enter, pass to and from and make use of an area and its facilities without undue difficulties. Constant reference to these basic requirements during the planning and design process of built environment will help to ensure that the possibilities of creating an accessible environment will be maximized.

3. Reachability - Provisions shall be adopted and introduced into the built environment so that as many places and buildings as possible can be reached by all people, including those with disabilities and elderly persons.

4. Usability - The built environment shall be designed so that all people, including those with disabilities and elderly persons can be use and enjoy it.

5. Safe – The built environment shall be so designed that all people, including those with disabilities and elderly persons, can move about without undue hazard to life and health.

6. Workability - The built environment where people work shall be designed to allow people, including those with disabilities, fully to participate in and contribute to the work force.

7. Barrier-free or non-handicapping - This means unhindered, without obstructions, to enable disabled persons free passage to and from and use of he facilities in the built environment.

Categories of the Disabled

The Welfare Department has categorized the handicapped into four categories:

i) Physically handicapped (polio, half-paralysed, cripple and spastic),
ii) Hearing-impairment (deaf and dumb),
iii) Sight-impaired (blind and partially blind) and
iv) Mentally retarded (Down’s syndrome, autistic and others).

Based on these categories, this study divides the disabled into two groups, i.e. permanent disabled and temporarily disabled. Both of these groups encompass the following categories:

i) Physically handicapped such as deaf, blind, no hands/legs;
ii) Mentally retarded or insane;
iii) Special children (Down’s syndrome, autistic and others);
iv) The elderly with limited physical capability;
v) Wheelchair users;
vi) Pregnant women; and
vii) Children and persons of stunted growth.

Abstract

It is hard to imagine living in a world devoid of colours. From the day we were born we are surrounded by a multitude of colours and colours determine who we are and our choices for survival. So pervasive are colours in our lives that they have always been taken for granted. Until, off course, we are deprived of colours or got ourselves labelled with the wrong colour! This paper attempts to explore the raw and refined aspects of colours and how they have been used in the past as well as the present and perhaps the future. From the mysterious white light of the sun to the delirious green tropical canopies, colours have never failed to captivate, excite or disenchant us. Colours are not only a significant part of the landscape but rather they originate from the environment itself.


PROLOGUE

I am about to bring you on an exciting journey. It will begin with facts as raw as a slice of red meat on a butcher’s table. But by the end of this, I hope to delve in finer things that surround this subject matter. However, if you find the journey boring, then it is the fault of the guide, never the journey.”

DIALOGUE

The discussion on colours, be they scientific, psychological or philosophical ones, is indeed very interesting and rewarding. It must have been so because since antiquity, scientists, philosophers, lawyers and barbers have thought and debated about the phenomena of colours that colour their lives.

For us mortal humans, colours are so common and have become a part of us that we sometimes become so careless as to take them for granted but with unpredictable consequences. Such things occur when we happen to support the wrong colour with true intention or display our true colour at the wrong occasion. In either case, the aftermath can lead to dire consequences. But are all creatures so fortunate as us to be able to see so many colours? Science indicated that many animals are not so fortunate in that they can only see in monochrome – in shades of black and white. So what kind of fools are the matadors who tempt to rage the bulls with red pieces of cloth when a simple black cloth or a stick will do the job? But then again a fiesta would not be a fiesta without the pomp and gaiety that colours can bring. So we know that colours are more for the human spectators than for the unfortunate bull. But scientists also noted that some animals can see colours that are even beyond the normal ability of human beings to see!

But seeing colour is one thing. The ability to communicate colours to another presents a different set of challenges. According to Tuan (1993), most major languages in the world lack the ability to name or describe colours adequately. This includes the English language. The inadequacy is so bad that Munsell decided to use letters and numbers to describe colours in his famous colour chart instead of English. Across the world the Maoris of New Zealand are said to perform better at describing some colours. They are able to describe many more colours of red. The Inuits of the Alaskan wilderness, on the other hand, can describe many more shades of white. They need to as their ice covered world largely appear in white and its variations.

But where do colours come from? Today, any school children knows that the light from our faithful sun carries seven colours – red, orange, yellow, green, blue, indigo and violet. And with the right tools we can “see” two more colours at the opposite end of the spectrum i.e. the infra-red and the ultra violet. But the amazing thing is that all these colours can appear united as one single colour. Sometimes what appear as pure is actually composed of diversity like the truth itself. Pass it through a prism, a single white light can generate its true composition. Pass through scrutiny truth itself may take on many forms. Therefore, it is the natural light that gives colours to everything that we see. The colours that we see vary with the light quality and intensity. Colours appear brighter when the sky is clearer and appear dull when the weather turns cloudy or hazy. In the absence of light, colours cease to exist.

Having known where colour originates we now turns to what makes colour. Again our science colleagues came to the rescue. Light, they say, are made up of particles that vibrate with a certain magnetic wavelength. The fact was explained by Isaac Newton back in 1666 with his prism experiment. Red has the longest frequency wavelength of the colour spectrum while violet and beyond have the shortest. So short and powerful are the latter wavelengths that they could penetrate through the human body and other objects giving rise to Roentgen’s X-ray.

When natural light of various colours hits objects, most colours in the spectrum will be absorbed by them. However, some will be reflected away. And it is the colours that are reflected away that enter the retina of the eye and are picked up by the special cells at the back of our eyes strangely named rods and cones. The sensitive rods and cones then transmit the sensations to the brain and we give names to the sensations as red, orange, yellow, blue and others relying solely on our knowledge and past experiences. A well experienced person can picked up between 150-200 different colours. Going by logic and the explanation given, a yellow mango is everything else but yellow. This is one of the contentions of a debate that will be delved in slightly later.

While we think that we know colours, describing them is not a simple matter. Those that have to deal with colours in their profession such as designers and colour consultants need to communicate well about their subject matter. And thus, we have come up with terms such as a hue to mean the type of colour, for example, red, orange and yellow. The degree of lightness and darkness of a colour is called its value. Thus, we can now describe bright pink or dark burgundy. And colour intensity refers to the “brightness or dullness of a colour.”

To further pacify our simple mind in recognizing and describing colours, we devised the colour wheel that has been the standard colour aid in any design studio. The wheel is based on colours that are considered primary because of their purity. These are red, yellow and blue. Then we have the secondary colours of green, orange and purple. They are called secondary colours because they are composed of a mixture of two primary colours. Blue mixed with yellow will give us green, red when mixed with yellow result in orange and blue when added to red will give us purple. But what if a primary colour is mixed with a secondary colour on the colour wheel? The combination results in tertiary colours such as yellow-orange, red-orange, red-purple and so on. While describing how a colour is formed seems to be easy enough, using colours to achieve an intended effect is not as simple. And thus the colour wheel tells us that there are combinations of colours that result in harmony while others can result in a discord. Colours that are found close to one another on the colour wheel are said to be analogous while those on the opposite side are complementary. Therefore, yellow, yellow-green, and yellow-orange are analogous colours. On the other hand, red and green or blue and yellow are complementary colours that are contrasting and yet in harmony.

While we have said quite a bit about colours and their origin and how they come about, the effects they have on our mood and behaviour are a matter of greater concern to us. To begin with, there are colours that are said to be warm. These include red and yellow and their combinations. The reason why these are grouped as warm colours is perhaps because they excite us and bring cheers to our lives. Warm colours generate activity and a faster heartbeat. They visually and psychologically warm the temperature of a space. Bright coloured flowers when used in a garden bring cheer and happiness. These colours are also said to be inviting, optimistic, encouraging, and stimulating to the appetite. Bright colours tend to blend objects, patterns and textures better than cool colours. Correctly used, warm colours visually reduce large spaces and contribute to intimacy. Young children love warm colours which help them to dissipate their boundless energy. They often use bright colours to express happiness.

On the other hand, cool colours work in the opposite. These colours such as green and blue have a more calming effect. They soothe our mind into a state of relaxation. And perhaps that is one reason they are preferred by the elderly. Researchers have pointed out that these are also the qualities that draw people to nature and the outdoors to escape the excitement and fatigue of city life. Used in confined spaces, these colours appear to recede and visually expand the existing space. A point of interest to those who are concerned about their diet – cool colours are believed to subdue the appetite! We would not want to eat so much rice that is coloured blue instead of yellow.

So powerful were the effects of colours on our psyche that lead some to describe colours as “the most personal and emotional of all the elements of design.” The ancient Greeks, Egyptians, Chinese, Indians and others are known to use colours to treat all sort of ailments. And colour therapy is making a comeback into our twenty first century lifestyles.

As mentioned earlier the effects of colours on us are influenced by a number of factors. Knowledge, experience and one’s culture may determine how we perceive colours and thus, how we react to it. Let us take a look at our reactions to colour from an instinctive viewpoint. Bright colours such as reds and yellows are called warm colours. And as mentioned earlier, they naturally cause our heart to beat faster. And thus we get more excited on seeing red than other colours. More adrenalin is pumped into our system. But for whatever reasons? Then we notice, too that poisonous plants and animals are brightly coloured. Could it be that the excitement that we feel today on seeing warm colours is a reminder of our distant past when our ancestors had to deal with venomous creatures?

Our response to colours depends also on our past experiences. It has been determined that we often associate colours with things and events in our lives. Here colour becomes very personal and difficult to generalise. Tuan (1993) mentioned how past experiences influenced our taste for colours when he said that before the industrial revolution, Europeans love to dress themselves in gay colours that bordered on the garish. However, after the industrial revolution, their tastes inclined towards grey and black. This is large due to the large amount of smokestack soot in the air that stained everything including clothing grey and black.

Likewise one’s culture too has a great influence on how we react to colour. To the traditional Chinese reds and yellows are the colours of happiness, good fortune and wealth. Thus, Chrysanthemums and Peonies are a favourite at celebrations. On the other hand, black is associated with misfortune, death and sorrow. However, among the Malays, black is the colour of courage and the mystics. We are taught that green is a colour of nature and therefore the Greenpeace Movement whose activities mainly centred on saving nature. A compact disc entitled “Touching nature, greening minds” is surely about educating people loving the natural environment. But green is also the colour that is associated with Islam. Surely the West would have some difficulty in interpreting this colour if “civilisations were to clash.” And currently it seems that the “red, white and blue “ are smothering all the other colours in hegemony.

Now let us take a look at what lurks behind the philosophy of colours. Great thinkers including Plato, Socrates, Averrhoes, Santayana, Descartes and others, just to name a few, stir up much debate about colour. One of their main contentions revolves around whether colours really exist! Ackerman (1990) claimed that:

“Colour doesn’t occur in the world, but in the mind. Remember the old paradoxical question: If a tree falls in the forest, and no one is around to hear it, does it make a sound? A parallel question in vision: If no human eye is around to view it, is an apple really red?”

A number of concepts have been proposed and are still being proposed to answer this question. One, for instance, focuses on objects as having colour properties while the other looks from the aspect of colour as a quality of the perceptual experience of the observer. The former seems to be favoured by those inclined towards the scientific approach to looking at the truth of the natural world.

Another problem with colour has been touched slightly earlier. If a colour of the object seen is that of the colour that is reflected and not absorbed by the object, then should we call the object by the colour that it is not? This seems to be another paradox of colour that has satiated philosophers’ appetite for many years.

And finally, we come to the theme of our conference “colours amidst green” Is green not a colour among colours? May be the conference organiser is confused or had a hidden agenda. Or perhaps green symbolises nature and colours are the diversity of life. I have not a faintest idea but if we are to argue that green is anything but green and colours are therefore green, then are we talking about the one and the same thing or nothing at all?

EPILOGUE

I seek no apology from the organiser nor you my dearest audience. For if you are lost then I am, too. For this is what philosophy is – seeking what is not rather than what it is…”

Pembangunan spesies baru dengan kepelbagaian warna seharusnya melalui proses penyelidikan dan pembangunan teknologi yang akan menjadi pemangkin kepada perkembangan industri landskap. Teknologi seperti penggunaan spesies hutan tempatan, pemilihan pokok eksotik yang sesuai, pembiakbakaan spesies orkid/hibrid dan juga kaedah bioteknologi dalam menghasilkan warna dan bahan tanaman akan membantu menambah kepelbagaian warna dalam landskap. Proses pemilihan dan pembangunan spesies berdaya maju dijangka akan dapat merealisasikan kehidupan masa depan yang lebih berkualiti, bersinar dengan pengolahan konsep yang tepat dan bersesesuaian dengan kehendak serta situasi landskap di masa hadapan.

Abstract

A better and comfortable life can be improved through creation of functional and quality landscape. Currently, landscape plants play important role of creating beautiful and conducive environment in tropical garden. Identification of new species for current and future landscape will add diversity to the local landscape design. The colour from the landscape plants gives very deep impact to man in planning and creating a good landscape design for the public. New species development with colour diversity is important through research process and technology development to enhance the landscape industry. The identification of local forest species, selection of the right exotic species, breeding of orchid species/hybrid and the use of biotechnology techniques in producing colour variety will help adding colour diversity in landscape. The selection and development of promising species is expected to develop better future. These include the process of conceptual planning and implementing an appropriate landscape garden.


Introduction

This working paper aims to outline the planning strategies and use of landscape plants, either native species or exotic in the future by focusing on various aspects of colours. Plants play important role as fillers on some landscape features and more importantly they add the aesthetic values to the landscape of a location. In today, manmade world, the aesthetic values of plants are becoming more highly appreciated. Plants provide a basic contact with nature and heighten pleasure in our surroundings. Their aesthetic value is more difficult to quantify than the values already discussed and is difficult to describe, in fact, without seeming trite or overly sentimental. Without elaborating on the principles of landscape design, the following are some of the aesthetic advantages that plants can provide:

1) Plants provide varieties of colour, form, texture, and pattern in the landscape.

2) Plants soften architectural lines and accentuate structural details.

3) Plants can form vistas, frame views, provide focal points, and define spaces.

4) Plants relieve the monotony of pavement and masonry.

5) Plants, particularly trees, make enticing play areas.

6) Plants offer cooling shade, pleasant fragrances, intriguing sounds, and serene settings.

7) Plants create the impression of a well-established place in new residential areas and minimize the raw, unfinished look.

8) Plants unify, giving coherence to visually chaotic scenes.


(Richard, 1983)



From the visual angle, colour on plant parts can increase the visual landscape quality in the city. Thus, people will interest to do activity with related to recreation for enjoyable life. Combination of softscape and hardscape to get colour balance will influence the surrounding temperature. Choices of various colour from plant in our country partly depend on newly introduce species through cultural manipulation, breeding programmed, and biotechnological research. Through this approach, plant characters such as free flowering plant, flowering longevity and uniformity could be identified.


Colour diversity in landscape plant

Colour is one of the inherent characteristics, through which a plant type could be usually distinguished. It has physiological effect to mankind and environmental quality (Booth, 1983). Bright colour plant give more conducive enviroscape and cheerful while plants with dark coloured give impact of dim and gloomy. All plant parts like leaf, flower, fruit, branch and trunk have unique colours to distinguish with other plant types (Ahmad Makmom, 2000). Plant colours help to strengthen their character in landscape composition, especially for large trees or any ornamental plants. Various colours will add variety and reduce monotone composition in any landscape design (Booth, 1983).

Many birds’ species are attracted to bright coloured flowers. Usually landscape plants with characters such as good canopy, bearing fruit and bright flower are suitable habitat for nesting. Plant characters such as bright flowers, aromatic and produce honey are some suitable criteria for attraction of insects like bees and butterflies. Some examples of these plants are Melastoma malabrathicum, Ardisia elliptica, Clerodendron spp. and Ixora spp.


Native plants

Native plant is a plant that grown naturally in any country (Corner, 1998) According to Muhammad and Mustafa Ali (1994), there are 250,000 around species of flowering plant in the world and 8000 species are estimated from Malaysian forest. From that estimation, it is not impossible to make these native species the biggest contributor in terms of flower, leaf and also fruit on colour diversity in landscaping.

The government has given encouragement and advocacy on native plant research. According to Ministry of Science and Environment, only 3% from the plant in our forest were used in research especially for medicine and health food purposes. This low percentage shows that too little research efforts have been done on local native species. Research in landscape development is still new and not much research has been done in this area.

In this millennium era, awareness on the important of local species planted has started. This is indicated through several new domesticated species in the tropical landscape garden. Malaysian native species like Eugenia oleana (Kelat paya) give very good impact in landscape through the bright colour on the leaf. The leaf colour change gradually from red, maroon to green is due to the phenological process of plant growth. Likewise, Bauhinia kockiana, a native species can produce very attractive orange flower with free flowering. Turnera sp. which produce yellow flower and glisten leaf colour has good landscape impact if planted with other ornamental plants.

Colour diversity that is produced through various part of plant such as leaves, flowers, stem and fruits need to be explored further in term of plant requirements to grow well in urban parks or green spaces. This is to sustain the natural of the plant and provide dominant impact to the landscape. As such, adaptation of native species should be done through specific procedures to ensure that data on certain growth requirement is always documented (Mustafa and Zulhazmi, 2003).

Evaluation and characterization of identified species against to new landscape environment is very important for the native plant. to determine plant function and usage in landscape. Basic procedures in selection of newly native species for used in landscaping should be followed as shown in figure below.






Figure 1. Development of adaptive procedures on native species


Exotic plant

Exotic plant means plant that is introduced by man to a new place (Corner, 1988) for certain feature such as attractive flowers, leaf colours or medicinal values. Previously, exotic flowers were introduced by navigators when they migrated from one place to another. Today, these exotic plants are commonly introduced in this country through demand in landscape industry.

For example, Hibiscus sp. which was brought from China long time ago were adapted to Malaysian environment and have been chosen as our national flower. These flowers have good characteristics like big flower, attractive shape and red colour, which symbolizes the courageousness. Since thereof, various hibiscus varieties with various colour spread in every space in the country.

The development throughout the nation was further boost up as Malaysia became the host country for the Commonwealth Games in 1998. Consequently, the landscape development was further enhanced. This was observed through the increasing demand for the landscape plants. This situation encouraged the local nursery and other landscape entrepreneur to introduce attractive species that produce flower and leaf with various colours. Consequently, ornamental plants like Heliconia sp., Turnera sp., Iresine hebstii, Duranta gold, Ficus yellow and other various species gained popularity. The different bright colours from these species give contrast to the existing green landscape. Dramatically colour produced by the exotic plant symbolizes that certain event begins.


Temperate plant

Many temperate plants were introduced during colonial era and a few varieties gained popularity in the local landscape such as Impatiens, Petunia, Poinsetia, Tagetes, Salvia, Catharanthus etc. The specialty of these temperate plants is the ability to produce bright coloured flowers or leaves. Visually this would attract attention to the viewers.

The ability to schedule the flowering time is an advantage to be planted in tropical garden. Temperate plants also have the ability to give instant effect on colour in landscape protocol areas such as roundabout, government buildings, prime avenues and royal palaces. Coloured leaves and flowers will increase the aesthetic value of landscape garden especially in the large cities like Kuala Lumpur and Putrajaya. Although the cost of planting material and maintenance is quite expensive its impact in landscape is very significant. These plants will give instant colour when planted at flowering stage in landscape garden. It also produces colour for a long time with frequent flower development or replace with new plants. Using temperate plants will enhance the scenario of a place due to the colour effect. Bright coloured flower will give visual effect on the compactness and further harmonise the place.


Orchid

Planting orchid as one of the landscape elements does not require high cost and maintenance as compared to other ornamental plants. This is proven through organized planning. Several factors that should be considered are as follows:

1. Selection of suitable variety
2. Quality of planting materials
3. Proper planting techniques
4. Proper plant maintenance

If all these procedures are observed, orchids will always produce flowers with various colours. Orchid selection for landscape is based on their flower uniqueness and colour. The following factors should be considered in varietals selection of orchid for landscape use:

1) Hardiness and vigour in growth

2) More tolerant to major pests and diseases

3) Fast growing and easily adapted

4) Free-flowering

5) Preferably produce big flowers with bright colour or small but many flowers

(Rozlaily and Hanim, 2003)



Orchid, with appropriate selection of variety and good maintenance, will give diversity of unique colour and attractive garden.

Technology contribution for production of various ornamental plant colours


Cultural manipulation

Growth and flowering manipulation of ornamental plants should be explored further. Several aspects like budgrafting technique, hormonal effect, light intensity and agronomic practices are a few approaches in manipulation and initiation of flowers.

The phenology and growth of individual plants should be documented to determine the time to first flowering, flower longevity and scheduling of colours in landscape. This could assist in manipulation of plant characteristic, whether to synchronize with the market demand or to manipulate their flowering, growth and form. Growth control is particularly important for potted plants. The various possible methods used are through mechanical technique, cultural practices, environmental manipulation and chemical treatment.


Plug system

Currently, both vegetative propagated flowering groundcovers and shrubs for bedding or indoor decoration are raised in polybags. The plant cuttings are normally stuck into medium in polybags and they are managed and handle individually. A propagation system that allows handling of plants in-group may increase production efficiency. One of the possible systems is plug system. Using this, the plants are sown or grown in specialized plug trays that are partitioned into individual cells per tray. The seedling or plant produced in each cell is called a plug. Production of plant materials using plug system has been recognized as the greatest improvement to date in bedding plant production industry in the United States and Europe. Use of this technique has influenced the materials handling methods, greenhouse design and automation, benching design and even determined the design of new cultivar and variety. The development of above technique also can produce big amount of planting material in one time and uniform. The plants are generally grown in a close proximity in a uniform media. Its can produce a big scale of colour to be use in landscaping (Hanim.et.al., 1999).


Biotechnology

Biotechnology is the technique or process use science related to living things such as micro organism, animal or plant for solving problems or make product which are useful to mankind. New biotechnology techniques allow researchers to take certain genes from a source organism and put those genes into another plant or animal. These techniques are called genetic engineering.

Biotechnology was practiced about 10,000 years ago when men domesticated animals and cultivated crop for food and clothing. In recent years, genetic engineering has been used for improvement of ornamental plants. It would help in the production of certain flower characteristics or traits that are desired in a directed manner. As opposed to normal breeding techniques which involves crossing, the genetic engineering approach would help in the transformation of the plant with the sole purpose of introduction certain traits that can be changed by genetic engineering. Several areas of flower crops have been studied most intensively using the techniques. One of which is the production of novel coloured flowers by the transformation of genes in the anthocyanin biosynthesis pathway. Using the antisense technology on genes such as Chalcone synthase and Dihyroxy flavanol reductase (DFR), new colours had been produced in Petunia. Other areas include enhancement of fragrance, plant that glows at night, pattern of flower and prolong the vast-life of flower by inhibition of ethylene production using antisense gene technology.

Today, however, transgenic approaches are also being introduced. The impressive results of traditional breeding are obvious to anyone who visits flower exhibitions and auctions (Joseph, M. 1998). These varieties, with their range of colours and patterns, constitute an enormous mutant collection for scientific study.


CONCLUSION


The use of plant in tropical garden will add colour diversity. The domesticated local forest species will contribute to colour diversity in landscape. Colour development is obtainable through saintific research. Several technologies such as genetic engineering, breeding program, cultural manipulation and plug system will contribute colour diversity in ornamental plants. With the above technologies production system could be carried out more efficient.

Roof Garden System

INTRODUCTION TO ROOF GARDEN SYSTEM


According to D. Nigel and K. Noel (2004), a green roof is a green space created by adding layers of growing medium and plants on top of a traditional roofing system. The construction and success of system depend on the specific needs and conditions of site. A roof garden is any planted open space, intended to provide human enjoyment or environmental enhancement, which is separated from the earth by a building or other structure (O. Theodore, 1999).

Commonly green roof is composed of simply at least two layers: the vegetation itself and the media or substrate within which they are growing. In addition most commercial green roof systems will also consisted of five or six components including, above the roof deck: a waterproof membrane, a protective layer, the growing medium, vegetation materials, and irrigation system. (D. Nigel and K. Noel, 2004 ).

Many of the problems associated with green roofs are a result from the faulty installation of one or more of the layers during the construction works and careless maintenance practices (D. Nigel and K. Noel , 2004 ).

Same with other roof on which it is to built, a roof garden is constructed in layers and the garden is in turn intimately connected to the roof. The roof top garden should include at least 4 essential component layers such as plantings, paving, furnishings and water features or sculpture. Once the design has been determined, installation is the key concern. The failure when installing the roof top garden component can cause significant damage to building and make it costly to repair it back. The importance thing that we should consider is choosing the highest quality of materials.


STRUCTURAL CONSIDERATION

Basically, roof garden can be separate into two type of roof garden that is intensive and extensive green roof. The differences between two types of roof garden are their visual appearance and in the amount of maintenance they may require, fundamentally, the division exists because of their relative overall weights.


Extensive gardens require minimal maintenance and behave as another from of roofing material. They are not intended for heavy foot traffic nor do they need to meet any additional safety standards. The intensive gardens created with the intent of active human use. These gardens require landscaping and regular upkeep. The intensive gardens may also need to comply with safety regulations regarding decks and public areas on raised structures. These regulations may require some kind of fencing or barrier to be installed with the intent of preventing people from slipping over the edge of the roofline. (source : http://www.interlog.com/~rooftop/greening.html).


The consideration that we need before choosing the type of roof garden is possible, therefore, relates directly to be load-bearing capacity of the roof structure of the building.


According to D. Nigel and K. Noel (2004), when calculating loading, “it must be remembered that the weight of green roof materials will vary greatly depending on how compacted and how moist they are” (page 59). Saturated weights of materials will indicate their maximum loading. The existing roofs measures can be taken to give additional support if necessary. Strengthen the roof with strategically placed additional structural components such as columns, beams and braces. Place the heaviest components of the roof on or near column heads and over beams. We should consider system that attach the green roof to wall or on small structures, such as garage or outbuilding, or consider constructing a framework around the building that enables the green roof to sit clear of the existing roof.


The typical loadings of extensive green roof system range from 80 to 150 kg per square meter. This is in contrast to typical intensive green roof loadings of 300 to 1000 kg per square meter or more (D. Nigel and K. Noel, 2004).

Table 1: Typical Loadings
INTENSIVE --------------EXTENSIVE
80 – 150 / sqmc -----------300 – 1000 / sqm

( Source : D. Nigel and K. Noel, (2004), “Planting Green Roof and Living Walls”, Timber Press Inc, Portland, Oregon, USA.)

a) ROOF SLOPE

Slippage is the major problem when we are talking about green roof sloped. Basically no green roofs avoid having a fabric membrane or membrane interface for example, at root barriers and sheet drains. Without additional slope stabilization measures, it is unwise to design green roofs for slopes steeper than 2:12, which equals around 9.5o or 17% slope (D. Nigel and K. Noel, 2004).




A Wooden Grid Provides Further Stabilization. We can solve this problem by the use of horizontal strapping, laths, battens, or grids. Finally by using these methods, green roof can readily be constructed on pitches up to 7:12 which equal 30o or 58% but to build on steeper than that we should use special media mixes and specialize devices.

b) STRUCTURAL / LOAD BEARING


Structural engineers divide loads into two categories: “dead loads” and “live loads”.
The Dead Load- Refers to the weight of the weight of the roof structure itself and any permanent functional element.
The Live Load- Includes element such as human occupant, rain, maintenance equipment and other items of a transient nature.

Component of eco roof assert that these systems lightweight generally requires little additional load bearing capacity from most buildings structural systems, and in some cases may be installed on existing buildings with no structural modification.

The green roofing system manufacturers that suggest that extensive landscape systems need not be heavier than gravel covering used on some roofs. According o Kolb’s article in Anthos, a German are covered with gravel (approximately 5cm), which has a load about 100 kg / m2. Using this load as guideline for an extensive system, Kolb suggests that many gravel roofs might be greened, without additional load reserves.

c) WIND

According to D. Nigel and K. Noel (2004) in their book “Planting Green Roof and Living Walls”, structures on roofs have to withstand high wind uplift because of their exposed position. This pressure varies across the surface of a flat roof, being relatively low in centre and at its most extreme near the edges and corners.
The layer of a green roof are therefore vulnerable o wind shear, particularly if the waterproofing layer is not bonded to the roof beneath and the green roof itself is acting as ballast to hold it down (D. Nigel and K. Noel, 2004).



Selecting Plant And Other Roof Garden Element.
(Source:http://www.sustainable-communities.agsci.ubc.ca/thesis/kp-6.pdf)

Nevertheless, a strip of gravel, stones or pavers around the edge of the roof and used vegetation barriers, preventing damage by plants to the edges of the roof where the waterproofing layer rises above the surface of the growing medium.

d) IRRIGATION

According to D. Nigel and K. Noel (2004), it has four main irrigation methods are used on green roofs that is:-

1. Surface spray with traditional systems. These are wasteful of water and can also encourage surface rooting which is vulnerable to extreme temperatures and moisture stress.
2. Drip and tube systems. These can either be pegged to the surface or buried in the substrate.

3. Capillary systems. Porous mats deliver water to the base of the substrate and are ideal for shallower a system, that is 20cm or less.

4. Standing water systems. These systems maintain a layer of water at the base of the roof.

GREEN ROOF CONSTRUCTION

The main function of the components or layers of green roof are include weatherproofing of the roof, protecting the roof surface from root penetration and damage, drainage, and the support and growth of the vegetation layer.

a) WEATHERPROOF MEMBRANE

Basically, there are 3 types of membrane we are using know that are the built-up roof (most commonly encountered and are composed of the familiar bitumen / asphalt roofing felt or bitumized fabrics), single-ply membrane (rolled sheets of inorganic or synthetic rubber material that are overlapped at the joints and sealed with heat, in the case of thermoplastic materials such as PVC) and the fluid-applied membrane (available in hot or cold liquid form that is sprayed or painted on to the surface of the roof and forms a complete seal when set, eliminating the problem of joints).

An effective waterproof seal to the roof is an essential prerequisite for all green roofs, and the importance of making sure this is effective and durable cannot be overstated (D. Nigel and K. Noel, 2004).

b) ROOT PROTECTION BARRIER

If the membrane on a roof upon which a green roof is to be installed contains bitumen, asphalt or any other organic material, it is crucial that a continuous separation is maintain between the membrane and the plant layer because the membrane will be susceptible to root penetration and the activity of micro-organisms- these organic oil based materials are not root proof. If the roof is not completely flat, then any pockets off collecting water can also form he basis of plant growth on a roof – again there be protection from roof damage (D. Nigel and K. Noel, 2004).

Balancing act of costs and benefits are main ecologist issues if we are talking about root protection barrier. Meanwhile some of commercial systems are based upon plastic base plate or metal because that form are a complete underlying structure to the green roof and isolate and raise the green roof completely from the underlying roof structure.

The membrane sheets are welded together to form a complete seal -it is essential that the welding is effective because any gaps or weaknesses will be exploited by the plant roots (D. Nigel and K. Noel, 2004).

c) DRAINAGE LAYER

Proper drainage is an importance thing when installing the roof garden. To maintain the drainage we should look to a several reason, which is: the protection of waterproof of roof membrane, precipitation falling onto a green roof and green roofs turn our normal interpretation of rainfall runoff on its head.

Drainage can be achieved in several ways. These techniques relate mainly to flat or very slightly sloping roofs. Where there is a more definite slope, which is, 5o or greater, drainage may effective without specific drainage layers. Combining a drainage layer with a water storage layer below it not only further reduces runoff compared to roof greening systems without such layer, by 11% to 17%, but acts as a reservoir for plants to draw upon in dry weather (D. Nigel and K. Noel, 2004).

The main types of drainage material are granular material (Coarse granular materials such as gravel, stone chips, broken clay tiles, scoria (lava rock), pumice, expanded shale or expanded clay granules, contain large amount of air or pore space between them when packed together in a layer or space), porous mats ( which operate similar way to horticultural capillary matting, act like sponges, absorbing water into their structure), and lightweight plastic or polystyrene drainage modules ( these modules vary tremendously In design and appearance and most sheets are thinner than 25mm).



Irrigation Lines Are Run Through Channels.
( Source : www.greentechitm.com )

A new designed of drainage medium are stronger, easily handled and cut, very lightweight drainage layer for roof gardens and planters of all kinds. Below grade, it protected from ultra violet light, it is permanent and highly efficient drainage medium (O. Theodore, 1999).

d) GROWING MEDIUM OR SUBSTRATE
The ideal substrate has to achieve the seemingly miraculous combination of being highly efficient at absorbing and retaining water while at the same time having free-draining properties. Substrate should be able to provide anchorage for the plants of the green roof. The ideal growing medium will comprise 30-40% substrate and 60-70% pore space. This will ensure good moisture retention capacity as well as aeration to the roots of the plants. If the pore space is saturated on along term basis, that is, continuously less than 15% of the substrate containing air filled pore space, then poor plant growth will result (D. Nigel and K. Noel, 2004).

For plant growth artificial soils can be superior to many natural soils provided they ate tailored for the specific type of vegetation they are to support. Artificially produced materials that have been used include vermiculite and perlite – both forms of heated and expanded mineral formed into granules. These are both extremely lightweight but it also have disadvantages in that they must be mixed with other materials because they cannot store nutrients and water and the particles of vermiculite tend to collapse aver time (D. Nigel and K. Noel, 2004).

Some Materials Used As A Basis For Green Roof Substrates.

Natural Minerals
1) Sand
2) Lava (scoria) and Pumice
3) Gravel

Artificial Minerals
1) Perlite
2) Vermiculite
3) Light expanded clay granules (LECA) Expanded shale
4) Rockwool

Recycled Materials
1) Crushed clay tiles, brick rubble
2) Crushed concrete
3) Subsoil


e) THE ADVANTAGES OF THE ROOF GARDEN SYSTEMS





System Provide Drainage and Root-Zone Airflow.
( Source : www.greentechitm.com )

1) Drainage Design - Water flows gravitationally through the modular system to the waterproofing layer and out to the roof drains.
2) Protection- The network of modules provides protection of the roof membrane during construction and maintenance activity from mechanical damage.
3) Weight- Eliminates gravel drainage medium typical of traditional intensive gardens. This is significant weight and labor savings.
4) Appropriate Soils- Each module can contain a totally distinct plant media thereby allowing the landscape architect maximum flexibility in the selection of plants.
5) Environment- Airflow beneath the root zone through the pallet channels develops deeper root structure and healthier plants.
6) Roof Membrane Repair- If there is leak in the roof membrane; modules can be easily removed and replaced later after leak fixed with minimal disruption to the garden.
7) Flexibility- The garden can be built off site and installed quickly upon completion of roof.


f) PROBLEMS TO CONSTRUCT THE GREEN ROOF IN MALAYSIA

The problems to construct the green roof can be divided into 4 that are:
1) People Thinking
Nowadays, in Malaysia the green roof concept not very famous or familiar with people in this country. The green roof is a new phenomenon that we start to learned. Unfortunately, people still weird to talk about roof garden and stick with idea garden only can provide / develop at ground level.
2) Promotion
That is because lack of knowledge about green roof and lack of promotion to design our roof. However green roof are specified by professional with limited plant knowledge, whether they be landscape architect or horticulturist. Many of landscape architect in Malaysia today not really knows about green roof and they can’t propose green roof into their design.
3) Budget
To built a green roof basically we should have a lot of money and the budget is the main constrain to built the green roof. The planting green roof is often the most neglected aspect of the whole installation process. This may be result of budget limitations.
4) Law And Regulation
Malaysia have their own guideline to built green roof but the guideline not very completely show the importance of green roof as part as the way to control Urban Heat Island (UHI). The statement in that guideline only based on design of roof top garden and no explanation the importance to built green roof.
5) Policy
Government should give subsidize to encourage the building owner to built roof top garden on their building.

EKO-PELANCONGAN

APAKAH ITU EKO-PELANCONGAN?


Pelancongan menjadi salah satu kegiatan sosial dan ekonomi yang paling penting pada masa sekarang. Jumlah pelancong dalam negeri dan antarabangsa semakin meningkat, Beberapa buah negara di dunia kini, cuba memajukan pelancongan untuk beberapa faedah tertentu.
Terdapat juga alasan yang kukuh tentang kemungkinan kesan negatif dan keinginan yang kian meningkat untuk memajukan sektor ini secara terancang dan terkawal yang dapat mengoptimumkan faedah, manakala mencegah sebarang masalah yang serius.
Selain kawasan yang baru membangun, kawasan yang telah mempunyai pembangunan pelancongan yang agak banyak kini mengkaji semula sektor pelancongan, manakala di kebanyakan tempat, jika perlu, ingin memperbaiki sektor pelancongan untuk memenuhi piawaian sezaman dan objektif persekitaran.
Pengiktirafan diberi secara beransur-ansur terhadap pentingnya membangunkan pelancongan bersama-sama sektor lain dengan cara yang bersepadu dengan mengekalkan sumber untuk kegunaan yang berterusan, di samping membantu memelihara dan bukan merosakkan kawasan semulajadi dan warisan sejarah.

Definisi Pelancong

Definisi yang diterima secara umum dan meluas untuk pelancong antarabangsa telah disarankan oleh Persidangan Bangsa-bangsa Bersatu tentang Perjalanan dan Pelancongan Antarabangsa yang diadakan pada tahun 1963. Definisi itu menyatakan bahawa seorang pelawat adalah “sesiapa yang mengunjungi mana-mana negara, selain negara tempat ia bermastautin, dengan sebarang alasan, selain alasan pekerjaan dari Negara yang dilawati’ WTO 1981. Istilah pelawat merangkumi dua jenis pelawat yang ketara:

1. Pelancong – pelawat sementara yang menetap sekurang-kurangnya 24 jam di negara yang dilawati dan tujuan lawatan tersebut boleh dikelompokkan seperti yang berikut:

a. masa lapang (contohnya rekreasi, percutian, kesihatan, agama atau sukan)
b. perniagaan
c. keluarga
d. misi dan
e. mesyuarat

2. Rombongan – pelawat sementara yang menetap kurang 24 jam di destinasi yang dilawati dan bukan untuk tujuan bermalam ( termasuk pelancong yang belayar untuk makan angin )

Pelancong tempatan pula ialah orang yang melawat negeri lain selain daripada tempat seseorang itu bermastautin, lebih dari 24 jam. Sebagai contoh, mereka yang tinggal di Kuala Lumpur, melawat ke negeri Terengganu dan Kelantan selama 5 hari 4 malam dikira sebagai pelancong, kerana melebihi tempoh 24 jam dari masa yang ditetapkan.

Definisi Eko-Pelancongan

Eko-pelancongan mempunyai definisi yang berbeza yang diterjemahkan mengikut kefahaman setiap individu. Maksud terdekat yang mendefinisikan eko-pelancongan adalah, merupakan pelancongan yang berasaskan alam semulajadi dan mempunyai nilai yang cukup untuk digunakan tanpa menjejaskan sumber asalnya. Terdapat pelbagai definisi yang diberikan oleh tokoh ilmuan berkenaan dengan eko-pelancongan, antaranya ialah:

Goodwin (1996, p. 288)
Low-impact nature tourism which contributes to the maintenance of species and habitats either directly through a contribution to conservation and / indirectly by providing revenue to the local community sufficient for local people to value, and thereforeprotect, their wildlife heritage area as a source of income.

Fennell (1999, p.43)
A sustainable form of natural resource-based tourism that focuses primarily on experiencing and learning about nature, and is ethically managed to be low impact, non-consumptive, and locally oriented (control, benefits and scale). It typically occurs in natural areas,and should contribute to the conservation or preservation of such areas.

Secara rumusannya, eko-pelancongan merupakan pelancongan yang berasaskan alam semulajadi, di mana, diharapkan agar pelancongan ini akan dapat menyumbang kepada penyelenggaraan bagi pemeliharaan dan pemuliharaan alam semulajadi dan hidupan liar. Bagi memastikan alam semulajadi ini terus terpelihara, sumber bagi eko-pelancongan ini hendaklah dimajukan secara terkawal bagi meminimumkan impak ke atas alam sekitar.

Pengaruh Sejarah Dalam Eko-Pelancongan

Pengetahuan sejarah tentang sesebuah kawasan merupakan perancangan pelancongan yang penting kerana pelbagai aspek sejarah yang lazimnya dinyatakan sebagai tarikan pelancong seperti tapak arkeologi dan tempat peristiwa bersejarah, dan telah mempengaruhi gaya hidup sezaman, seni, dan kraftangan. Sejarah kawasan juga mempengaruhi sistem nilai sosial serta sikap yang merupakan pertimbangan sosiobudaya dalam pelancongan. Sejarah kawasan tidak perlu dikemukakan secara terperinci, tetapi harus menonjolkan latar belakang yang diperlukan untuk memahami unsur penting untuk analisis pelancongan.

Subjek sejarah merupakan unsur terpenting yang hendak ditekankan didalam laporan ini, kerana dari sejarahlah terbentuk nilai sosio-budaya yang dapat kita tatap pada masa sekarang ini. Sejarah juga mengajar kita untuk menilai ekonomi, pertahanan, pentadbiran dan juga keagamaan. Tidak keterlaluan jika dikatakan bahawa sejarah memainkan peranan yang besar, tetapi bukan yang terpenting dalam eko-pelancongan.

Faktor-Faktor Lain Yang Menyumbang Kepada Eko-Pelancongan

Tarikan pelancong dapat dikelompokkan dengan cara yang berbeza-beza, kesemuanya berasaskan logik. Walaubagaimanapun, segala pendekatan ini membandingkan tarikan berdasarkan aspek sejarah, lokasi, dan penilaian. SIstem pengelasan yang lazim digunakan adalah:

1) Tarikan semulajadi yang berdasarkan ciri persekitaran semulajadi
2) Tarikan budaya berdasarkan kegiatan manusia
3) Jenis tarikan istimewa yang dicipta secara buatan.

Bagi eko-pelancongan, tarikan semulajadi merupakan aspek utama yang mempromosikan sesuatu tempat itu, selain dari sejarah tempat tersebut. Antara tarikan semulajadi yang utama adalah:

· Iklim

Lazimnya iklim yang panas, cerah digemari oleh kebanyakan pelancong, khususnya dari pelancong dari luar negara, terutamanya apabila dikaitkan dengan tarikan lain seperti kawasan pantai, laut, dan gunung-ganang yang menyediakan kegiatan rekreasi. ‘ pemuliharaan ’ iklim yang diingini menerusi pengawalan pencemaran udara diperlukan untuk pelancongan.

· Keindahan Pelancongan

Secara keseluruhannya keindahan pemandangan semulajadi menjadi dorongan utama untuk dilawati, khususnya jika langkah pemuliharaan telah digunakan untuk mengekalkan kebersihan dan sifat semulajadi dalam persekitaran. Landskap semulajadi yang indah seperti Hutan Lipur Sekayu,yang mempunyai air terjun Sekayu yang begitu nmendamaikan.

· Kawasan Pantai dan Laut

Rangkaian pantai yang memutih, antaranya Pantai Mengabang Telipot, Pantai Batu Buruk dan sebagainya menjadi dorongan untuk para pelancong dari dalam dan luar Negara mengunjungi negeri Terengganu ini. Kawasan ini juga dikaitkan dengan pelbagai kegiatan rekreasi air seperti menaiki bot, luncur air, berenang dan sebagainya.
