Model Prediksi Pengaruh Limbah Cair Hotel Terhadap Kualitas Air Laut Di Pesisir Teluk Kupang (a Prediction Model of Liquid Waste Hotel Impact on the Sea Water Along the Coast of Kupang Bay)

摘要

Most of the hotels located along the coast of Kupang Bay dump their effluent liquid waste to the sea. This action will definitely affect the sea water quality and in turn, will unavoidably give deep impact on the life of both microorganism and all the living things in the sea. This research intends to make an impact prediction on the sea water quality over the dumping hotels\u27 affluent liquid waste to the sea. The parameters which are observed are oil and fat and orthophosphate of the hotels\u27 affluent liquid waste. While the observed parameters of the sea water quality are turbidity, oil and fat, and chlorophyll. The methods used to take and test the sample are SNI and USEPA. And to analyze the data, testing on both correlation and regression are applied. The result of the study reveals that the turbidity of the sea water within the range of 0 to 25 meters can be predicted from the level of oil and fat of the hotels\u27 affluent liquid waste by using regression model equation y = 0.0051 x + 4.8456 and y = 0.0015 x + 4.5440. Meanwhile, the level of the sea water chlorophyll within the range of 25 to 75 meter can be predicted from the level of orthophosphate of the hotels\u27 affluent liquid waste by using the equation of regression y = 0.0430 x + 0.0004 and y = 0.0075 x + 0.0001.
