ABSTRACT
In this era of complex and modern technology, water pollution has become a
severe problem for the world to cope with. Enormous expenditure has been delivered
to resolve this serious matter. Unfortunately, most of the efforts are to no avail
without the people awareness and responsibility towards clean environment. To
prevent this phenomenon from continuing spread, researchers have found a solution
by using the power of nature. It is called Aquatic Plant System. This concept is an
improvised technique from the wetland system. The system is an alternative in
wastewater engineering especially for water treatment. The water treatment act as
secondary filter to our wastewater after the treatment. Uniquely, the wetland system
can operate by itself without so much works. This study was conducted to explore
the feasibility of using plant species to remediate effluent from palm oil mill effluent.
To achieve the objective, Ipomoea Aquatic was chosen for this project. This plant is
tested with wastewater from LCSB Oil Palm Plantation in Lepar for two weeks. The
water parameters that have been monitored were BOD5, COD, pH, TSS, and Oil and
Grease. From the overall experiment results, we found that the removal percentage as
follows, for BOD5 is 80.1%, 75.2% for COD, 78.2% for TSS and 85.4% for Oil and
Grease. Thus, Ipomoea Aquatic is potential to reduce toxic compounds in wastewater
and it economic since it use the natural way.

ABSTRAK
Pada zaman moden yang canggih dan kompleks ini, pencemaran air telah
menjadi isu dan masalah besar kepada seluruh masyarakat di dunia. Perbelanjaan
besar telah diperuntukkan untuk menyelesaikan masalah ini. Namun, hampir semua
usaha yang telah dijalankan menemui jalan buntu kerana ianya tidak akan berjaya
tanpa kesedaran manusia itu sendiri mengenai kebersihan alam sekitar. Untuk
mengelakkan fenomena ini daripada berlaku lebih buruk, para penyelidik
menyarankan penggunaan teknik tumbuhan akuatik. Ia merupakan teknik yang
diolah dan dipertingkatkan daripada teknik tanah bencah. Sistem tanah bencah ini
merupakan satu alternatif dalam kejuruteraan air sisa dalam merawat pencemaran air.
Sistem ini berfungsi sebagai penapis kepada air yang menjalani rawatan di loji
rawatan air. Uniknya, sistem ini boleh beroperasi secara semulajadi tanpa
memerlukan penyelenggaraan yang kerap. Projek ini dijalankan untuk mengkaji
kebolehan tumbuhan akuatik menyingkirkan air sisa pemprosesan kelapa
sawit.Dalam mencapai matlamat dan objektif ditetapkan, spesis tumbuhan akuatik
telah dipilih untuk menjayakan projek ini.Tumbuhan tersebut ialah
Kangkung(Ipomoea Aquatic). Tumbuhan ini diuji dengan air tercemar yang
diperolehi daripada Kilang Kelapa Sawit LCSB di Lepar selama dua minggu. Bacaan
parameter yang akan digunapakai dalam projek ini adalah BOD5, COD, pH, pepejal
terampai dan Minyak dan Gris. Daripada kajian ini, didapati bahawa penyingkiran
adalah 80.1% untuk BOD5, 75.2% untuk COD, 78.2% untuk pepejal terampai and
85.4% untuk Minyak dan Gris.Maka dengan ini, Kangkung (Ipomoea Aquatic)
berpotensi mengurangkan bahan cemar di dalam air sisa dan kosnya rendah kerana
menggunakan kaedah semulajadi.

CHAPTER 1
INTRODUCTION
1.1 Introduction
Palm oil comes from the fruit of the Elaeis guineensuis tree, also called the
African oil palm tree. Native to Africa and now extensively cultivated in Malaysia,
the tree bears a fleshy fruit which is the source of both palm oil and palm kernel oil.
Palm oil is entirely different than palm kernel oil, which has a higher amount of
saturated fat and has to be heavily processed to be extracted. Palm kernel oil is, in
general, unhealthy.

Palm oil is the most versatile of all vegetable oils. It is consisting of 50%
saturated fat and 50% unsaturated fat. It is semi-solid at room temperature. It is also
odourless and tasteless. These two properties have made palm oil ideal for baked
goods and packaged foods. Palm oil also works well with fried foods and stir-fry
because its quality doesn't diminish under extremely high heat. Unlike most
nutritional oils, palm oil is highly resistant to oxidation, giving it a longer shelf life.
Technological development has transformed the Malaysian palm oil industry
into a strategic and well planned industry that responds to global challenges. In
particular, genetic knowledge since as early as 1912 first led the phenomenal growth
of the industry through the planting of tenera instead of dura palms. This was
complemented by the government allocating land to the poor and landless to plant
more oil palm, in great part causing the area to increase from 62 000 ha in 1975 to
1.02 million hectares in 1980 and 2.03 million hectares in 1990. By 2007, there were
4.3 million hectares of oil palm, constituting nearly two-thirds of the national
agricultural area (Figure 1.2). Malaysia continues to be the world’s largest palm oil
producer with a production of 16.20 million tonnes in 2006. The success of the crop
is largely market driven with good long term price prospects for palm oil making oil
palm more attractive than most other crops. Palm oil contributes more than one-third
of the national agricultural GDP, generating RM 31.81 billion in export earnings in
2006, making it one of the pillars of Malaysia’s economy. At present, the industry
employs more than 1.5 million people in the core and related sectors.

Aside from being one of Malaysia’s highest money earning industry, palm oil
production is also one of the major potential, if unabated, organic polluters of the
environment producing very high strength waste effluents. In 1992, Malaysia
produced about 6.7 million tonnes of crude palm oil contributing to 15.9 million
cubic metres of palm oil mill effluent (POME). Raw POME has a high biochemical
oxygen demand (BOD) which is about one hundred times more than that of sewage.
Realising the escalating situation, measures to counter pollution from POME
have been deployed. In order to regulate the discharge of effluent from the crude
palm oil (CPO) industry as well as to exercise other environmental control, The
Environmental Quality (Prescribed Premises) (Crude Palm Oil) Order, 1997 and The
