Abstract

Abstract Jabon landfill is located above the land belonging to the local government of Sidoarjo city with 8 hectares. The study’s objective is to evaluate the current state of Jabon landfill management using the Integrated Risk Based Approach (IRBA). Risk Index (RI) assessment results using IRBA obtained a 548,08 value with a category of moderate hazard evaluation so that the Jabon site can be gradually forwarded and rehabilitated into a sanitary landfill. Waste composition measured dominated by three types of waste biodegradable waste, non-biodegradable, and hazardous waste 69%, 29%, and 2%, respectively. The strategy needed for revitalizing the Jabon landfill is developing a system to minimize the impact of pollution on water, soil, and air so that it will be more environmentally friendly.
