Measurement of Utilization of Tofu Production Waste for Biogas with Green Productivity Method and IFAS-EFAS Analysis: Case Study in CV. Proma Tofu

Abstract

Many household-scale tofu industries in Indonesia still do not have a liquid waste treatment process. The reluctance of the tofu factory owner to treat the liquid waste because it is difficult to process, plus it is considered not to produce added value. Whereas tofu liquid waste has the potential to produce biogas in an aerobic process. By processing the liquid waste of the tofu factory into biogas, the factory owner not only contributes to preserving nature but also increases his income by reducing fuel consumption in the tofu-making process and can be utilized by the surrounding community so as to increase the factory's income. The type of Green Productivity method used is green use. With the aim of trying to preserve the environment and produce products with environmentally friendly designs. Meanwhile, using IFAS and EFAS analysis can provide alternative solutions for solving company problems. Using the analysis of internal factors (strengths, weaknesses) and external factors of the company (opportunities and threats) as well as the calculation of the IFAS and EFAS matrices, the best alternative is the Growth Strategy. The company has very supportive opportunities and strengths so that it can maximize existing opportunities. By continuing to support the company's aggressive growth policy. As well as using various strategic formulations resulting from the IFAS and EFAS analysis matrices, this research can realize the balancing and maximizing the productivity and impact of waste on the environment.
