Abstract

Sugar production wastewater is considered as one of the most fundamental factors that influence drinking water and human health. This study aims at analyzing and evaluating the reality of Assalaya factory wastewater and its ramifications on water quality and human health.
The methodology employed for this study is laboratory analysis of the 17 physiochemicals parameters, which include 20 samples of wastewater from different locations. The physical parameters that have been analyzed are TDS, Turbidity, TSS, Odor, and Color; while the chemical parameters are pH, Total hardness, Total Alkalinity, NH3, Ca, PO4, BOD, COD, Cl, NO3, NO2, and Na. The study used the spatial analysis interpolation IDW on GIS software to understand the range of affected areas considering only on the chemical substances that have been used as the primary input to produce sugar such as Ca, Cl, Na, and PO4. Furthermore, the study makes questionnaires to recognize the community perception about the physiochemical wastewater and the health impact within the area.
Data analysis reveals that the physiochemical water of the river has been changed proportionally by factory wastewater based on SSMO, the wastewater leads some consequences on human health presented in generating several types of disease.
The study recommends biological treatment to follow the environmental water policy and establish the final treatment near the river administered by the government instead of factory administration. The factory ought keeping abreast of global transformation in the field of production such as Eco-friendly and Green economy and be familiar with the sustainability concept.
Keywords: Factory wastewater, IDW interpolation analysis, community perception, and health impact
