Abstract

This study investigates the water quality and landuse at the Tasik Chini, Pahang, Malaysia. Recently, water quality and biodiversity of the Tasik Chini was significantly deteriorated due to the mining and agriculture activities nearby the Tasik Chini. The water quality was significantly deteriorated by the metals from the mining area and high consumption of fertilizer from the agriculture activities. Therefore, this study was significantly urgent to determine the water quality and to characterize the type of landuse at this lake. The assessment of the water quality was conducted at in-situ and laboratory experiments. Samples of water were collected at Laut Kenawar, Laut Serodong, Laut Gumum, Batu Busuk and Jeti UKM. Measurements of dissolved oxygen, pH, ammoniacal nitrogen, chemical oxygen demand, biochemical oxygen demand, total suspended solids, and metals were conducted in this study. Land use analysis was performed using QGIS to determine the type of landuse. The dominance landuse are forested area (69.48%), followed by agriculture area (9.69%) and mining area (9.60%). The water quality analysis shows that the water quality index of the Tasik Chini was dominantly under Class (III). The concentration of dissolved oxygen was significantly low and the existence of Fe, Cu and Al significantly deteriorated the water quality of the Tasik Chini. Therefore, suitable mitigation measures are required to preserve the water quality and biodiversity of this lake. The findings from this study could provide better environmental management to control landuse development and sustain the water quality of the Tasik Chini.
