Abstract

Tofu industrial liquid waste contains high organic matter, if it is discharged into the environment without being processed first, it will have a negative impact in the form of environmental pollution. Currently, most of the tofu industry is still a small household scale industry, for example in Bara-baraya one of the tofu industries is not equipped with a wastewater treatment unit. The Bara-baraya tofu industry is located right in the middle of a residential area, so this can cause disturbance to the surrounding environment. This study aims to determine the quality of the tofu industrial wastewater in the Bara-Baraya Timur Village, Makassar City in terms of pH, BOD, COD, and TSS parameters. The type of research used is observational research with a descriptive approach. The method of examining samples from the parameters of BOD, COD, TSS and pH in the tofu industrial wastewater refers to the SNI for water quality testing methods and is examined at the Makassar Health Laboratory Center. The results of the inspection of the quality of tofu waste water compared to the Minister of Environment Regulation No. 5/2014 are the pH parameter 3.85 (not eligible), COD parameter 499 mg/L (not eligible), TSS parameter 4.777.50 mg/L (not eligible), and BOD parameters 1.771.88 mg/L (not eligible). The conclusion in this study is the quality of tofu wastewater in waste samples that have not undergone treatment at the wastewater treatment plant (IPAL) located in the tofu industry located in RW 4, Bara-Baraya Village, Makassar City, does not meet the requirements and exceeds the quality standards that have been set. determined by the government so that it can cause pollution to the surrounding environment.

Abstract

In the soldiers' housing complex, a large volume of rice washing water is wasted, even though this waste can be used as a liquid organic fertilizer with high nutritional value for plant growth. Community service is a concrete manifestation of the role of academics in making a positive contribution to the development and safety of the surrounding environment. This activity not only aims to transfer useful knowledge and technology, but also encourages community independence in utilizing local potential that is often not optimally managed. One common problem encountered in many households is the high volume of wasted domestic waste, including rice washing water waste, which has long been considered worthless. This training provides a positive contribution to the community because it can be an alternative in finding alternative fertilizers to overcome fertilizer scarcity and prevent environmental pollution. This community service activity is a form of knowledge transfer from academics to the wider community to provide benefits based on the results of research that has been carried out on campus, especially the process of making liquid organic fertilizer.
