| Summary: | Almost every tofu production process requires water. Tofu production also produces wastewater that has the potential to cause environmental pollution, such as bad odors, degradation of groundwater quality, and piles of solid organic waste. One way to assess the production activities of industry in managing and using water and knowing the impact of these production activities on society is through water footprint analysis. This thesis is a case study of five white tofu industries and six yellow tofu industries in Giriharja, Kebonjati Village, Sumedang Regency. The tofu industry in Giriharja has implemented the processing of whey using anaerobic WWTP (Wastewater Treatment Plant) with a capacity of 120 m3 which can reduce COD (chemical oxygen demand) by up to 93% and produce biogas which is used by 87 households. This study aims to (1) calculate the value of the water footprint on tofu production, (2) determine the sustainability status water footprint of tofu production through multidimensional analysis using the RAPFISH (Rapid Assessment Technique for Fisheries technique), and (3) developing a strategy to reduce the value of water footprint of tofu production through a SWOT-QSPM analysis (Strength, Weakness, Opportunity, and Threat - Quantitative Strategic Planning Matrix). The data collection methods were observation, interview, questionnaire, quick scan, and literature study. Research respondents consisted of nine tofu producers, 52 residents, association Kelompok Pengrajin Tahu Giriharja, association Kelompok Tani Giriharja, Kebonjati village apparatus and civitas Research Unit of Clean Technology of LIPI. Based on the results obtained, it was concluded that: (1) the value of water footprint in the white tofu production is 101 m3/ ton, while the yellow tofu production is 114 m3/ ton; (2) the water footprint of tofu production in Giriharja has the status of 'Quite Sustainable' with a RAPFISH value of 59.24%; and (3) strategic recommendations for nine tofu industries based on the SWOT-QSPM results are the utilization of anaerobic WWTP effluent in agriculture, reusing wastewater from the cooling process, the yellow tofu industry does not carry out the cooling process, building additional facilities to treat tofu wastewater, using local soybeans, requesting government support for anaerobic WWTP management, increasing the biogas fee rate, and the yellow tofu industry replacing water with whey in the second cooking process.
