Abstract

Urban plastic waste management remains a major challenge in many Indonesian cities, including Banjarmasin. The increasing volume of plastic waste has led to material accumulation and limited utilization of shredding residues, particularly high-density plastic fractions that lack economic value. This community service program aimed to improve plastic waste sorting performance in order to optimize the value of plastic shredding residues through the application of appropriate technology. The methodology integrated Participatory Rural Appraisal, Asset-Based Community Development, and Community-Based Technology approaches, involving 14 staff members of the Banjarmasin Municipal Waste Bank from June to November 2025. Technological implementation included the development of a waste sorting device, operational assistance, and training on utilizing plastic residues as raw materials for paving block production. Evaluation was conducted across technical, operational, and partner capacity aspects by comparing conditions before and after program implementation. The results demonstrated a significant improvement in plastic waste sorting performance, reflected in increased sorting capacity, enhanced operational stability, and improved work efficiency. Improvements in operational flow contributed to reduced plastic accumulation and increased utilization of shredding residues for paving block production. Partner capacity also improved, particularly in understanding circular economy principles, technical capability in paving block production, and awareness of business development based on plastic waste utilization. Overall, the application of appropriate technology successfully optimized the value of plastic residues, increased economic added value, and strengthened an integrated urban waste management system based on circular economy principles and community empowerment.

Abstract

Perkembangan teknologi manufaktur aditif mendorong pemanfaatan material berbasis limbah plastik, seperti Polypropylene (PP) dan High-Density Polyethylene (HDPE), dalam bentuk pelet sebagai bahan baku filamen 3D printing. Namun, studi yang secara langsung membandingkan karakteristik filamen dari kedua material pada kondisi proses yang serupa masih terbatas. Penelitian ini bertujuan untuk menganalisis secara komparatif karakteristik filamen berbasis PP dan HDPE melalui proses ekstrusi. Metode yang digunakan adalah pendekatan eksperimental dengan variasi suhu dan kecepatan motor, serta pengukuran diameter, homogenitas, kekuatan, dan laju ekstrusi filamen. Hasil menunjukkan bahwa sistem bekerja stabil pada ≥50 PWM dengan deviasi suhu ±2°C. PP menghasilkan diameter 1,15–1,75 mm dengan nilai optimal 1,75 mm pada 160°C dan 60 PWM serta laju ekstrusi lebih tinggi. HDPE menghasilkan diameter 1,10–2,05 mm dengan nilai optimal 1,77 mm pada 170–175°C dan 70 PWM serta menunjukkan ketahanan yang baik. Perbedaan ini dipengaruhi oleh viskositas dan perilaku aliran material. PP lebih sesuai untuk kestabilan dimensi, sedangkan HDPE untuk kebutuhan kekuatan material.
