Development of A Methodology for Selection and Assessment of Liquid Waste Processing Technology from Oil Palm Industry Using Analytical Hierarchy Process (AHP)

Abstract

The waste produced by the palm oil industry contributes a lot to environmental damage if it is not operated properly. Waste consists 70% of raw material amount which is almost half in the form of liquid. There are many alternatives for treating palm oil industry wastewater, from the most advanced technology to conventional technology. The difficulty in choosing and evaluating and applying the most appropriate technology for certain companies from various alternative technologies is a big problem. Therefore, a Decision Support System has been developed to assist in identifying, evaluating and selecting the best technology for wastewater treatment. In this study, three operations have been developed in MySQL, a database for waste treatment technology; Introduction of criteria using the Analytical Hierarchy Process (AHP) approach. The AHP method is also a proven tool for the decision-making process for selecting palm oil industry wastewater treatment technology. This model in the palm oil industry, therefore the software database can be updated and the program algorithm can be modified according to user needs. This study can assist in decision making and optimize the reprocessing of liquid waste from palm oil mills.
