Abstract

The Alur Ilmu UKM is a large storm water channel that serves to store water and flows into Langat River. The primary objective of this study are to identify the water quality and pollution levels, the sources of which may cause pollution and to measures the control pollution that occurs in the area. Water sampling is needed to be carried out in order to determine the quality of water. The sampling water was taken during no-rain and after rainfall. The area includes UKM Forest Reserve (Hutan Pendidikan Alam – HPA), Student Cafeteria (Teres Eko Niaga), Restaurant of Fakulti Sains dan Teknologi (FST), Student Centre (Pusanika), Fakulti Pendidikan Islam (FPI) and UKM Mosque. Eight water quality parameters i.e consisting of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), pH, Turbidity, Total Suspended Solids (TSS), Total Kjeldahl Nitrogen (TKN), Temperature, Oil and Grease (O&G) were measured. The results shows that the water quality are in a class III and IV according to Water quality Index (WQI) and the water meet the standard B that set out in the Regulations of the Environmental Quality (Sewage and Effluent).

Abstrak

Alur Ilmu UKM merupakan sebuah saluran air ribut besar yang berfungsi untuk menakung air dan mengalir ke Sungai Langat. Kajian tentang kualiti air dan punca-punca pencemaran di Alur Ilmu UKM telah dijalankan. Objektif utama kajian ini adalah untuk menentukan kualiti air disepanjang Alur Ilmu, membina pangkalan data punca-punca pencemaran di Pencemaran titik dan Pencemaran bukan titik serta mencadangkan langkah-langkah yang boleh diambil untuk mengawal pencemaran dan rehabilitasi. Untuk menentukan kualiti air, beberapa kawasan persampelan air dilakukan. Kawasan tersebut adalah di Hutan Pendidikan Alam (HPA), Restoran Fakulti Sains dan Teknologi (FST), Teras Eko Niaga, Pusanika, Fakuliti Pengajian Islam (FPI) dan masjid UKM. Pengukuran dilakukan ke atas lapan parameter kualiti air yang terdiri daripada Permintaan Oksigen Biokimia (BOD), Permintaan Oksigen Kimia (COD), pH, Kekeruhan, Jumlah Pepejal Terampai (TSS), Jumlah Nitrogen Kjeldahl (TKN), Suhu, Minyak dan Gris. Secara keseluruhannya, kualiti air berada dalam kelas III dan IV mengikut Indeks Kualiti Air (IKA) dan memenuhi piawaian B yang dinyatakan dalam Peraturan-Peraturan Kualiti Alam Sekeliling (Kumbahan dan Efluen).
