Abstract
Liquid waste generated from the production process of large rubber plantations reaches approximately 26.4 m3 / ton dry rubber. The high liquid waste is because water is the most resources needed during the production process. This waste can cause adverse effects on the environment if not managed properlySeveral liquid waste treatment technologies have been implemented in rubber plants in Indonesia, but there is no assessment of the best liquid waste treatment technology to be applied in rubber plants in order to avoid adverse environmental impactsTherefore, in this study conducted an assessment of liquid waste treatment technologyusing AHP and PROMETHEE methods. The determination of criteria and weighting is based on expert consensus using the Delphi method. Assessment of liquid waste treatment technology by providing effective solutions and criteria for liquid waste treatment technology. The results of this study indicate that the Active Sludge System with priority weight (0.4550) is superior to other liquid waste treatment technology alternative that is Pond System (0,2995) and the phytoremediation system (0,2456). Evaluation of the assessment by the PROMETHEE method also shows that the Active Sludge System is ranked first.
