Abstract

Tamblingan Lake is a natural lake has a function as a sources of raw water dan tourism destination. The change in the cultivation of farmers around Tamblingan from hard cropping pattern (coffee) to the annual plantations (flowers and horticulture), if can’t be controlled may cause decreased of water quality. The objective of this study to determine the pollution load from the agricultural element, and the water quality index based on existing condition. This research conducted tree stages; chemical analysis of water quality indicators in laboratory, analysis of water quality status using STORET method and water pollution load analysis using application AVSWAT Program. Based on measurement of water quality parameters obtained Nitrate (NO3-N) amount to 1,002 mg/l, BOD5 amount to 934 mg/l, DO amount to 683 mg/l and phosphorous as P amount to 764 mg/l. Water quality analysis using STORET method, total score from the results of the calculation is -10. These value with range -1 to10 so that status of water quality of Tamblingan Lake is “B Class”. The pollution load of existing land Tamblingan Lake for phosphorous inflow of 14,374 mm/ton/ha, Nitrate inflow of 47,515 mm/ton/ha/month, BOD5 inflow of 469,635 mm/ton/ha/month, DO inflow amounted to 2054,8317 mm/ton/ha/month. The value is between (-1) to (-10), the Water Quality Status of Tamblingan Lake Class B with contaminated lightly lake water condition. Recent Publications 1.
