Spatial Distribution of Livestock Waste Water Polluition and Its Treatment in Saddang Watershed

The Saddang River is the principal river in the Saddang Watershed (DAS) with degraded water quality. Sources of pollution include residential neighbourhoods, industries, and commercial districts. In addition to being a site for exchanging basic necessities, the livestock market is also a specialised area for dealing with animals, particularly buffalo and pigs. Due to improper waste management, the enormous quantity of animals harms the ecosystem. Animal waste runs directly into natural and manmade channels leading to the Saddang river, which is just 64 metres from the livestock market. Therefore, actions must be taken to improve waste treatment technology and lessen the pollution burden. This research consists of determining the spatial distribution of waste pollution or waste distribution patterns using a Geographic Information System (GIS) application, beginning with initial sampling at five stations on the Saddang River and one at the outlet. The sample is tested in the laboratory and the results are validated by determining water quality standards based on the Pollution Index according to Decree No. 11 of the Minister of the Environment. Using organisms to break down livestock waste with Gambas, Zeolite, Bio-ball, Jap mat, and water bamboo plants as buffer media, a reactor with a biofilter and phytoremediation system is used for waste treatment. The results demonstrated that waste treatment with biofilter and Phytoremediation systems effectively reduced waste for physical parameters, namely Dissolved Residue (TDS) of 78.64 percent, Suspended Solids (TSS) of 97.93 percent, Turbidity of 96.90 percent, for parameters Chemical COD of 97.69 percent, DO of 98 percent, Nitrate of 29.29 percent, Ammonia of 66.35
