ABSTRACT
The problem that occurs downstream of the Jembatan Dua river is that it has been polluted by the parameters of BOD, COD and PO4 with the results of the measurements being 3 mg/L, 37 mg/L, and 0.3 mg/L, respectively. This study aims to analyze the conceptual model of pollution control strategies in the downstream Sentani watershed. The method used in this research is the SWOT (Strength, Weakness, Opportunities, Threats) method with four SWOT strategies, namely SO (strength-opportunities), WT (Weakness-Threats), SO (Strength-Opportunities) and WO (Weakness-Opportunities). The results showed that the pollution load of TDS and TSS continued to increase from 2016-2019. The conceptual model of the strategy for controlling water pollution in the downstream Sentani watershed is the SO (strength-opportunities) strategy with coordinates (0.26; 0.18). This SO strategy needs to be implemented in the short term, namely: utilizing internal strengths to capture external opportunities. SO strategies include: Increasing environmental law enforcement, increasing leadership commitment and the role of government institutions in handling pollution and mainstreaming sustainable development, and making the lake an ecotourism area by keeping the lake unpolluted.
