Abstract

Wastewater produced from the water management process must be in accordance with environmental quality standards in order to reduce the potential risk for environmental damage and human health. One of the pollutant compounds in wastewater that is the problem in this article is Chemical Oxygen Demand (COD) which is not in accordance with the environmental quality standards of the Indonesian government. The purpose of this study is to analyze the process capability of wastewater treatment, especially for COD pollutant parameters. Furthermore, several methods are used in this study such as IMR control maps, process capabilities, and Fishbone diagrams. The results show that the COD parameter has an average Cp index value of around 1.03and an average Cpk of approximately 0.44. Therefore, it can be concluded that the wastewater management process still needs to be improved to produce wastewater that conforms to specified standards. This research can be the basis for subsequent research related to improving the quality of wastewater management processes.
