ANALISA KUALITAS AIR WADUK UNDIP SEMARANG SEBAGAI SUMBER AIR BERSIH (ANALYSIS OF RESERVOIR WATER QUALITY UNDIP SEMARANG AS A SOURCE OF PURE WATER)

Abstract

The existence of a reservoir is one man’s attempt to make ends meet and maintain the availability of water thoughout the year. As an academic institution, the University of Diponegoro (Undip) create a reservoir as a form of contribution and dedication to the community. However, Reservoir Undip have problems with garbage and the proliferation of water hyacinth plants (Eichornia crassipes) uncontrolled. Given these problems, it is necessary undip reservoir water quality analysis which consists of analysis TSS, TDS, salinity, and pH. In this study, observed on 5 variables with 5 different sampling point. It was concluded that the highest undip reservoir water pollution occurred in the southern edge of the reservoir to the TSS value of 1050 mg / l, TDS 419 mg / lt, 0.3% Salinity and pH 5. While the pollution of water reservoirs undip lowest is in the middle of the reservoir with TSS value of 515 mg / lt, TDS 316 mg / lt, 0.1% Salinity and pH 6. Keywords: reservoir undip, TDS, TSS, salinity, and pH
