Abstract

Rally lab merupakan kegiatan pengabdian dari Departemen Teknik Fisika Institut Teknologi Sepuluh Nopember (ITS). Kegiatan ini bertujuan untuk meningkatkan literasi sains dan teknologi, serta membangun minat siswa SMA Wijaya Putra Surabaya terhadap pendidikan STEM (Science, Technology, Engineering, and Mathematics) melalui program kunjungan laboratorium secara bergantian atau rally lab. Kegiatan ini diikuti oleh 30 siswa kelas 11 jurusan IPA Teknik melalui kunjungan ke empat laboratorium Teknik Fisika ITS, yang dirancang untuk memperkenalkan konsep engineering design melalui pengenalan alat dan peragaan eksperimen. Evaluasi menunjukkan bahwa 89,7% siswa belum pernah mengikuti program serupa, dan 55% siswa menunjukkan ketertarikan pada alat inovatif seperti 3D printer. Selain meningkatkan wawasan dan motivasi siswa, program ini juga memberikan manfaat bagi guru berupa ide untuk karya tulis dan media pembelajaran. Dengan keberhasilan program ini, diharapkan integrasi pembelajaran berbasis laboratorium dapat memperkuat pendidikan STEM di Indonesia.

Abstract

Desa Kalanganyar, Sidoarjo merupakan wilayah dengan potensi besar di sektorperikanan dan pengolahan hasil tambak, namun menghadapi tantangan serius dalampengelolaan limbah organik yang belum termanfaatkan secara optimal. Lebih dari65% sampah harian di TPS3R desa ini berupa limbah organik yang berisiko menimbulkanpencemaran lingkungan dan gangguan kesehatan jika tidak ditangani secaratepat. Program pemberdayaan masyarakat ini mengimplementasikan sistem budidayalarva Black Soldier Fly (BSF) sebagai solusi berbasis teknologi. Larva BSFmampu mengonversi limbah organik menjadi biomassa bernutrisi tinggi untuk pakanikan serta menghasilkan kasgot sebagai pupuk organik yang memperkuat ekonomisirkular desa. Kegiatan dilaksanakan secara partisipatif melalui tahapan survei kebutuhan,perizinan, instalasi sistem modular MagoBox Tower Lite, pelatihan teknis,hingga evaluasi produksi. Satu unit sistem menghasilkan 14,5 kg larva kering per siklus(potensi untung Rp1.015.000) untuk pakan, dengan nilai SROI 13,68, yang berartidampaknya 13 kali lipat biaya investasi. Masyarakat masih memerlukan dukunganeksternal untuk mengelola limbah dan mengintegrasikan berbagai sektor desa(perikanan, pertanian, peternakan) dalam satu ekosistem ekonomi sirkular terpadu.

Abstract

TPS3R Kalanganyar Village has considerable potential in waste management and Nile tilapia (Oreochromis niloticus) farming. However, limited farming capacity, high feed costs, and restricted marketing access have hindered the optimization of its economic potential. This community service program aimed to strengthen food security by implementing a circular economy-based community empowerment model. The program consisted of developing fish and Black Soldier Fly (BSF) maggot farming infrastructure, implementing digital technologies, and conducting community training and assistance. The program resulted in the construction of two biofloc-based Nile tilapia ponds, one modular maggot cultivation rack, a water quality monitoring system, a digital marketing platform, and an aquaculture learning center. Training provided to 15 TPS3R managers increased participants' knowledge by 58.5%, with an overall satisfaction rate of 87.5%. Economic analysis indicated that the developed aquaculture system has the potential to generate a gross income of approximately IDR 4,320,000 per production cycle, while BSF maggot cultivation could substitute approximately 4.3% of commercial fish feed requirements. These findings demonstrate that integrating circular economy principles with digital technologies can enhance aquaculture capacity and contribute to strengthening community-based food security.

Abstract

Improving the productivity of small and medium enterprises (SMEs) through production mechanization requires a reliable and sustainable energy supply. This study aims to design, implement, and evaluate the performance of a 1.2 kWp off-grid rooftop solar photovoltaic (PV) system to support the operation of the Olikan fish cracker processing SME in Kalanganyar Village, Sidoarjo Regency, Indonesia. The research methodology included energy demand assessment, PV system design, system installation, user training, and system performance monitoring and evaluation. The results indicate that the installed PV system generated an average of 1.77 kWh/day during the monitoring period, providing sufficient electricity to operate the production equipment. Further evaluation revealed that energy availability was not the primary constraint limiting productivity improvement. Instead, production capacity was predominantly influenced by market demand, raw material availability, and production scheduling. The implementation of the off-grid rooftop PV system provides a reliable alternative energy source while enhancing productivity, promoting energy independence, and supporting the operational sustainability of fisheries-based SMEs.
