Abstract

The Sembalun Mushroom Initiative aims to strengthen food security and resilience to disasters in Sembalun Bumbung and circumstance villages through the utilization of biogas energy for the pasteurization process of mushrooms. These areas are prone to disasters, making the supply of food and sustainable energy a major challenge. The project utilizes cow dung waste as an environmentally friendly biogas source to support pasteurization and mushroom cultivation. Traditionally, mushroom pasteurization processes still use firewood, which triggers deforestation, high carbon emissions, and health risks from smoke. The community service team from the University of Mataram has developed biogas technology as an alternative solution. The biogas installation at the At-Tazkiyah Islamic Boarding School was completed in May 2024 and began operating in July 2024, thereafter a mushroom house has been built for mushroom cultivation in early 2025. During this community service project, a gas pasteurization system is installed and used for pasteurization, followed by training and capacity building for the community in utilizing green energy sources. The aim is to introduce a transition to environmentally friendly technologies, as well as to support innovation, sustainability, and community engagement. The activities are an international collaboration between the Postgraduate Program and the Faculty of Engineering at University of Mataram and the Fatoni University in Thailand. It is expected to expand Unram's international exposure and strengthen cooperation between countries.

Abstract

Pemeliharaan isolator berperan penting dalam menjaga keandalan jaringan transmisi listrik, khususnya pada sistem 150 kV. Pada Tower T.04 jalur transmisi 150 kV Sengkol–Kuta ditemukan kerusakan pada isolator gantung tipe kaca berupa korosi pada steel pin. Kerusakan ini diperkirakan disebabkan oleh polusi asap pembakaran lahan yang bercampur dengan kelembapan udara, sehingga menurunkan kekuatan mekanis dan kemampuan isolasi. Untuk mengatasi permasalahan tersebut dilakukan pemeliharaan korektif melalui penggantian isolator kaca dengan isolator polimer ber-corona ring. Tahapan pekerjaan meliputi persiapan dan pengamanan area kerja, pemeriksaan visual, pelepasan isolator lama, pemasangan isolator polimer, serta pemeriksaan akhir untuk memastikan kelayakan operasi. Isolator polimer dipilih karena memiliki ketahanan lebih baik terhadap korosi dan membutuhkan pemeliharaan yang lebih sedikit dibandingkan isolator kaca. Hasil pemeliharaan menunjukkan perbaikan ini mampu memulihkan fungsi isolasi, meningkatkan kekuatan mekanis, dan menjaga keandalan jaringan transmisi di lingkungan dengan tingkat polusi tinggi.
