Abstract

The process of tanning leather produces waste that causes problems in the form of pollution to the environment, especially river water such as changing color to black and causing a foul odor. In addition, polluted water also causes health problems such as itching of the skin. Waste water treatment has been carried out by several factories, such as in Sukaregang, Garut, Indonesia. However, it is necessary to conduct an evaluation to assess whether the results of the waste treatment process have met the specified requirements. The purpose of this study was to evaluate the wastewater produced by the ^X^ tannery factory located in Sukaregang, Garut, Indonesia. In this study, an analysis of wastewater quality standards was carried out in the form of measuring pH, measuring total suspended solids (TSS) using the gravimetric method, measuring chemical oxygen demand (COD) using the titration method and measuring oil and fat using the gravimetric method. Based on the requirements stated in the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number: PP.21/Menlhk/Setjen/Kum.1/7/2018, the parameters that meet the requirements are pH and oil and fat content while the levels of TSS and COD far exceed the limit of maximum rate.
