Developing a Sustainable Solid Waste Management System Using Analytical Hierarchy Process (AHP) Method at Pondok Institutions in Kelantan

Abstract

This study focuses on developing a sustainable solid waste management system at Pondok institution using the Analytical Hierarchy Process (AHP) method. Besides that, the types of solid waste generated were determined. Three alternatives were underlined, which are composting, recycling, and both composting and recycling. This research utilised the convenience sampling method, where a constructive questionnaire was used as a research instrument. An online questionnaire with detailed descriptions was distributed to two (2) Pondok institutions in Kelantan. After that, empirical research using the AHP method was carried out to find the priority weights of alternatives to develop a sustainable solid waste management system in Pondok institution. There are two significant findings in this research. This research revealed the types of solid waste generated by Pondok institutions that are food waste/farm waste, plastics, papers, metal and aluminium tin, and glass. The highest types of solid waste generated are organic waste, and the least is glass. Besides that, this research discovered the most appropriate sustainable solid waste management system alternative to be implemented in Pondok institutions, which is composting and recycling. Developing a sustainable solid waste management system will reduce excessive solid waste generation, reduce space for dumping sites, and overcome environmental problems.
