Abstract

Karangilang Recycling Center (Reduce, Reuse, Recycle Solid Waste Transfer Station) served as one of the backbones for reducing waste, including in metropolitan cities such as Surabaya. There were a total of 12 recycling centers in Surabaya, and one of them was Karangilang Recycling Center. Karangilang Recycling Center operated to facilitate waste sorting in its surrounding area and also handled waste collected from several main roads in Surabaya. The planned capacity of this station was 5 tons/day, but it had only been receiving less than 2.5 tons/day of waste. This research aimed to evaluate the management process at Karangilang recycling center Karangpilang, both from a technical and financial perspective. Sampling to determine the volume of waste entering the Karangilang Recycling Center was conducted using load count analysis over a period of 8 days. The waste composition was also analyzed using the SNI (Indonesian National Standard) approach during the same 8-day span. Process analysis was carried out through observation and calculation of the existing recovery factor at Karangilang Recycling Center. Material Flow Analysis (MFA) was used to assess the flow of recycled waste at the study site and in the surrounding subdistrict area that formed its service zone. Recommendations were provided based on the evaluation of both technical and financial aspects.
Enhancing equipment quality, optimizing waste flow processes, and upgrading composting capacity are critical steps to increase technical efficiency The reduction of solid waste at Karangpilang Recycling Center reached 33% of the total incoming waste. This reduction figure could still have been increased by maximizing the recovery factor (%RF) of the managed waste. The MFA of the generated waste showed that the input originated from waste collection, then the main process sorting, composting, and selling recyclable solid waste to collectors. Improving equipment quality, optimizing waste flow processes, and upgrading composting capacity had been identified as critical steps to enhance technical efficiency. From a financial perspective, the Net Present Value (NPV) and Benefit-Cost Ratio (BCR) indicated that the activity had not been feasible. To address this issue, the volume of incoming waste needed to be increased, and the amount of recycled material had to be raised. This improvement would have led to an increase in revenue for the Karangpilang Recycling Center.
