Abstract

Waste pickers in Jambi city reduce solid waste by collecting and sorting recycled waste at the ‘Solid Waste Temporary Shelters’ or Tempat Pembuangan Sementara (TPS). However, most waste pickers cannot improve their performance due to challenges confronting waste pickers and lack of attention from the government and the public. This research identified and quantified the solid waste collected and marketed by individual waste pickers and collectors ‘pengepul’. Convenience sampling methods with literature reviews, questionnaires, and interviews were carried out in this study. Most respondents were male waste pickers, 67%, and women, 33% (n=100). The average daily collection rate of male waste pickers is 10.43 kg/day. For female waste, pickers are 7.92 kg/day (waste category: plastic bottles, cardboard, and wastepaper), with an estimated recycling rate of 0.09%-0.89%. Meanwhile, collectors have an average sales rate of 2-5.5 tons/month, with an estimated recycling rate of 1.5%. The recycling value of waste pickers and collectors could be more optimal, impacting the average income of waste pickers Rp. 581,250/month which showed that the market is neither profitable nor socially protected. The research findings could help develop a waste pickers' integrated system to improve the implementation of the circular economy.

Abstract

Waste is a serious problem in developing countries due to infrastructure limitations, one of which is the city of Pekanbaru. The existence of the landfill triggered the arrival of informal workers such as scavengers to collect waste as recycled product materials. Most scavengers live below the poverty line, even though scavengers have a role in restraining the waste generation rate in landfills. This study aims to analyze the potential integration of scavengers in the Muara Fajar Landfill Area with formal workers using integrated waste management, "Clean Pekanbaru Movement." The research was conducted using observation methods, interviews, and questionnaires filled out by scavenger and collector respondents in the landfill area. The recycling rate (RR) of the Muara Fajar landfill area is 1.08%, and the average individual RR of 150 scavengers is 0.72%. The proposed integrated waste management concept is the "Clean Pekanbaru Movement," which manages the Muara Fajar landfill area and acts as a recycling industry player. The study results show that the recycling rate at the Muara Fajar landfill only reaches 1.08%, while the average individual scavenger only reaches 0.72%. The Pekanbaru Clean Movement model is proposed as a solution that integrates scavengers into a formal waste management system with regulatory support and the recycling industry. As many as 82% of respondents are willing to participate in this program for a fixed income and better social security. This study concludes that the potential for waste generation because of recyclable materials is still huge, and the potential for integration is very possible at the Muara Fajar Landfill, Pekanbaru. Implementing this program can improve the social welfare of scavengers and reduce the environmental impact due to the open waste disposal system.

Abstract

Inefficient solid waste management contributes significantly to environmental degradation and marine debris pollution, particularly in port areas. Tanjung Priok Port, Indonesia’s largest port, handles intensive logistics activities that generate substantial waste from vessel operations, port services, and river-borne inputs. This study assesses the quantity, density, and composition of waste at three waste disposal sites to support sustainable management strategies. Sampling was performed over eight days following SNI 3964:2025. Waste sampling took place at three temporary waste storage sites (Tempat Penampungan Sementara, TPS) within the port area. TPS 01 recorded the highest waste generation (21.07 tons/day), followed by TPS 03 (3.59 tons/day) and TPS 02 (1.38 tons/day). Waste density ranged from 220.21 to 293.13 kg/m³, with organic waste, plastics, and paper comprising the dominant components. Statistical analysis confirmed significant differences among sites, highlighting spatial variability and the need for targeted mitigation measures. Waste characteristics at Tanjung Priok Port closely relate to the intensity of operational activities. TPS 01 shows the highest total amount at 168.59 tons, equivalent to an average of 21.07 tons per day, followed by TPS 03 with 28.68 tons (3.59 tons per day) and TPS 02 with 11.06 tons (1.38 tons per day).
