Abstract

The fried-shallot industry generates large quantities of waste cooking oil, which is commonly stockpiled and, in some cases, distributed to nearby residents for household cooking. This practice poses environmental risks and potential health impacts, asdegraded oil continues to be consumed. These challenges form the basis of this community engagement program, whichaims to support partner enterprises in managing waste cooking oil to prevent negative impacts while transforming it into value-added products. The program aimed to assist the partner in managing used cooking oil into high-value, eco- friendly products in the form of biodiesel. The implementation used the Participatory Rural Appraisal (PRA) approach, emphasizing active participation of the partner in all stages, including socialization on waste management, biodiesel production training, equipment fabrication, and establishment of a biodiesel production unit at the partner’s site. The results showed a significant improvement in the partner’sknowledge and skills in waste management; 100% of the used cooking oil waste was successfully processed into biodiesel, providing additional income opportunities. Moreover, the activity encouraged the industry to operate more sustainably andcontribute to green energy provision. This program demonstrated that technical assistance combined with simple technologycan create an economically and environmentally sustainable production system.

Abstract

Program pengabdian kepada masyarakat yang dilaksanakan oleh Universitas Islam Sultan Agung Semarang di SD Negeri Bajo Lohoa, Desa Tanomeha, Kecamatan Kaledupa Selatan, Kabupaten Wakatobi, bertujuan mendukung revitalisasi dan digitalisasi sekolah di wilayah 3T (Tertinggal, Terdepan, Terluar) yang masih menghadapi keterbatasan pasokan listrik sebagai kendala utama dalam pembelajaran berbasis teknologi. Kondisi keterbatasan energi listrik tersebut menyebabkan proses digitalisasi pembelajaran belum berjalan optimal dan membatasi pemanfaatan perangkat elektronik pendukung kegiatan belajar mengajar. Untuk menjawab permasalahan tersebut, tim pengabdian bekerja sama dengan PT PLN (Persero) ULP Wangi-Wangi melaksanakan serangkaian tahapan kegiatan yang sistematis, meliputi survei lapangan guna mengidentifikasi kebutuhan teknis sekolah, koordinasi dengan pihak sekolah dan PLN, pemasangan perangkat SuperSun berbasis tenaga surya berupa panel surya dan instalasi sistem kelistrikan pendukung, uji coba operasional peralatan, serta sosialisasi penggunaan dan perawatan sistem kepada guru dan pengurus sekolah agar mampu mengelola perangkat secara mandiri dan berkelanjutan. Hasil kegiatan menunjukkan bahwa sekolah kini memiliki sumber listrik alternatif yang lebih stabil dan andal, sehingga memungkinkan penggunaan perangkat pembelajaran digital secara optimal, meningkatkan efektivitas proses belajar mengajar, serta memperkuat pemahaman warga sekolah terhadap konsep energi terbarukan dan pentingnya transisi menuju energi bersih. Dengan demikian, program ini tidak hanya mendukung peningkatan kualitas pendidikan melalui digitalisasi, tetapi juga berkontribusi nyata terhadap pemerataan akses energi dan pendidikan serta peningkatan literasi energi bersih di wilayah kepulauan seperti Kabupaten Wakatobi.

Abstract

XYZ MSMEs engaged in convection screen printing recorded a fairly high level of product process defects that resulted in product defects with an average defect of 5%. Some of the causes of failure in the production process include images that are not clearly printed, images that are sit-inspired, inappropriate cuts, untidy seams, t-shirts that are stained with screen printing ink, and faded screen printing results. Efforts to reduce these various problems are carried out by identifying potential failures in the production process using the Multi Attribute Failure Mode Analysis (MAFMA) method. This method produces the highest alternative weight value so that it makes it easier to make action decisions. There is one most potential failure, namely untidy seams with a total value of 0.244. The improvement strategy is carried out by paying attention to the causes of potential failures by looking at influential factors, namely human, machine, material, method and environmental factors analyzed using fishbone diagrams. Operators who are not careful and in a hurry when working, the condition of sewing machines and screen printing presses that are poorly maintained, sewing thread materials and screen printing dyes that are inconsistent in quality, there are no SOPs for operators and an uncomfortable working environment that affects the quality of the sewing and screen printing results produced. Improvement proposals are made by conducting training for workers, performing scheduled machine maintenance, checking materials before the production process, selecting trusted suppliers, making SOPs for operators and regulating production room conditions so that operators are comfortable when working.
