Abstract

MYCL (Mycotech Lab) is a biomaterial company that develops sustainable leather alternatives using mushroom mycelium through a circular economy approach. One of its main products, Mylea, is a mycelium-based leather material developed for fashion and lifestyle applications. Although this production process provides environmental benefits compared with conventional leather and synthetic materials, it still involves occupational safety and health (OSH) risks. Workers may be exposed to biological hazards, chemical agents, high-temperature equipment, mechanical hazards, and ergonomic risks during production activities. This study aims to identify workplace hazards, assess risk levels, and determine appropriate control measures in the mycelium leather production process at MYCL. The research applied a qualitative approach through direct observation, interviews, and documentation of production activities, including growth medium preparation, sterilization, inoculation, incubation, harvesting, pressing, drying, and finishing. Hazard identification and risk assessment were conducted using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method. The results showed that identified hazards ranged from medium to very high risk levels. The highest risks were found in the sterilization process due to exposure to high-temperature autoclave surfaces and pressurized steam, as well as in the pressing and forming process involving hydraulic equipment. Other risks included contamination, biological exposure, ergonomic issues, and heat exposure. Recommended control measures include improving personal protective equipment (PPE) compliance, strengthening safety procedures, conducting routine equipment maintenance, improving workplace sanitation, implementing ergonomic practices, and providing worker training. The findings provide an overview of occupational risks in mycelium-based manufacturing and support safer and more sustainable industrial operations.

Abstract

Kecamatan Cilengkrang, Kabupaten Bandung, memiliki potensi peternakan sapi perah yang tinggi namun dihadapkan pada permasalahan pencemaran lingkungan akibat penimbunan limbah kotoran ternak secara terbuka di kawasan berlahan miring. Adopsi teknologi biogas sebagai solusi energi sirkular terkendala oleh karakteristik topografi, keterbatasan ruang, serta inefisiensi pada proses perancangan reaktor yang masih dilakukan secara manual oleh penyedia jasa industri. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk mengimplementasikan solusi terintegrasi melalui perancangan infrastruktur fisik dan sistem digital. Pelaksanaan program menggunakan metode Participatory Technology Development dengan pendekatan kolaborasi multidisiplin (Teknik Kimia, Teknik Sipil, dan Sistem Informasi) yang melibatkan Kelompok Peternak Sapi Perah Manglayang (KPSPM) dan mitra industri PT Anugrah Triple-Cycle. Secara fisik, dibangun reaktor biogas beton bertulang yang adaptif terhadap lahan miring, berfungsi sebagai penstabil tanah, dan dilengkapi sistem saluran masuk (inlet) gravitasi yang mengeliminasi kebutuhan pengadukan manual. Untuk mendukung infrastruktur tersebut, dikembangkan aplikasi berbasis web dan mobile bernama OWREN yang berfungsi mengotomatisasi perhitungan potensi biogas, dimensi reaktor, dan estimasi kebutuhan material berdasarkan parameter lapangan. Integrasi teknologi fisik dan digital ini diharapkan mampu menuntaskan masalah sanitasi dan kemandirian energi bagi peternak, sekaligus mempercepat proses perancangan bagi mitra industri, menciptakan model teknologi tepat guna yang efisien, berdaya guna, dan mudah direplikasi.
