【 摘 要 】

Problem statement: It is important to find the status of water quality at converted peatswamp forest into oil palm plantation. This study was conducted to find and determine the waterquality at peat swamp forest of Batang Igan, Sibu Sarawak. This study presents a status on the waterquality of peat swamp forest at the area. Approach: In-situ data and a total of 72 water samples werecollected at four sampling stations (S1, S2, S3 and S4) in three different months of July, August andNovember 2009. In-situ data included temperature, conductivity, Dissolved Oxygen (DO), pH andTurbidity. Analysis for ammoniacal nitrogen (NH₃-N), Biological Oxygen Demand (BOD), ChemicalOxygen Demand (COD) and Total Suspended Solids (TSS) were conducted in the laboratory. Resultsfor water quality parameters are as follows, temperature range (26.85-32.90 °C), pH range (3.03-3.84),DO range (1.99-8.05 mg/L), conductivity (42.07-98.72 µS cm^-1), TSS range (1-54 mg L^-1), turbidity(0.39-9.80 NTU), BOD range (0.5-9.8 mg L^-1), COD (0-17) and ammoniacal nitrogen (0.2-0.42 mgL^-1). The Water Quality Index (WQI) which was calculated based on six water quality parametersnamely dissolved oxygen, biological oxygen demand, chemical oxygen demand, pH, ammoniacalnitrogen and total suspended solids, was representative of the state of water quality in Batang Igan peatswamp forest. Results: Based on WQI, S1 was categorized under Class III while S2, S3 and S4 werecategorized under Class II. Conclusion: The physical-chemical parameters of water in Batang Iganpeat swamp forest were in normal range or in class I and class II that is in good water status except forpH and dissolved oxygen for the water; however it is normal condition for peat water.
