Analisis produktivitas dan kinerja lingkungan dengan menggunakan konsep green productivity (study kasus PT.ABC)

PT. ABC is a private company engaged in the provision of clean water services under the auspices of PT. Kaltim Prima Coal). Constraint occurs is in the process of drinking water treatment and wastewater sludge yield potential as a source of environmental pollution. Other problems also exist in the high BOD and Cod content of wastewater after measurement. As for the number of connections installed for corporate customers, there are only 2,895 connections, while from the data of PTABC, the company's connection target is 12,589, so from the total target of PT. ABC has only been able to obtain a connection of 23% of the target to be achieved. a need to increase water production by PT. ABC in order to increase the quantity of clean water production for all consumers. The concept of green productivity (GP) can be used in the search for solutions to increase productivity and protect the environment. The study begins by identifying the root cause of a lot of liquid waste and a low amount of water production, setting objectives and targets, choosing the resources and information available to arrange alternative green productivity. There are two alternatives, the selected alternative in this study are alternative 2 merge maximizing the raw water intake, repair Well Bore Tj.Bara , and the use of wastewater that is the use of waste as material raw returned by first applying multilevel aeration technology to reduce levels of COD and BOD5 in wastewater. based on the use of the cost benefit anlysis method the company's productivity and EPI increases if implementing this alternative will increase 40% from the initial production of 114% to 154%. And the initial EPI index total value of -20.8 increased to 18.8 so it rose 39.6 which indicates an increase in productivity and environmental performanc
