Abstract

This study aims to calculate the cooling load required in Cold Storage to store fish catches. Cold Storage is an important facility in the fisheries industry to maintain the quality and freshness of the product. Accurate cooling load calculation is essential to design an efficient and energy-saving refrigeration system. The methodology used includes data collection on Cold Storage specifications, environmental conditions, and characteristics of the stored products. The cooling load is calculated by considering factors such as transmission loads through walls, roofs, and floors; product loads; air infiltration loads; internal loads from lights, equipment, and personnel; and other loads. The calculation results show that the total cooling load for Cold Storage with a certain capacity is 17.68 kW. Sensitivity analysis was conducted to evaluate the effect of various parameters on the cooling load. This study also provides recommendations for optimizing Cold Storage design and operational strategies to improve energy efficiency. The results of this study can be used as a reference in designing and operating Cold Storage for more effective and economical storage of fish catches.

Abstract

Although numerous studies have been conducted on voltage and current imbalance in electrical systems, research specifically focusing on these conditions in fishing vessels, particularly those operating in the Natuna Sea, remains very limited. This study aims to analyze the voltage and current imbalance on the generators of purse seine fishing vessels operating in the Natuna Sea, based on the IEEE Std 45-2002 and BKI Volume IV Year 2022 standards. A quantitative approach was employed, involving direct measurements of voltage (both line-to-line and phase-to-neutral) and current at the main distribution panels of five fishing vessels. The reference standard for Line Voltage Unbalance Tolerance (%LVUT) according to IEEE Std 45-2002 is ≤ 3%, while the acceptable limit for current imbalance according to BKI Volume IV Year 2022 is ≤ 15%. The results showed that the average voltage imbalance across the five vessels was below the IEEE tolerance limit (≤ 3%), with the highest recorded value being 4.34% on KM. Palembang Indah II. Meanwhile, current imbalance generally complied with the BKI limit (≤ 15%), except for KM. Rezeki Bersama, which exhibited the highest current imbalance at 30.48%. These findings highlight the need for mitigation measures, such as load redistribution and phase balancing, particularly on vessels with significant imbalance levels. This study provides practical contributions to improving the reliability of vessel electrical systems and enhancing operational safety within Indonesia’s marine fisheries sector.

Abstract

Nelayan dalam melakukan operasi penangkap ikan umumnya dilakukan sampai malam hari sehingga membutuhkan listrik untuk sistem penerangan dan navigasi. Beberapa nelayan KUB Kuda Laut di Bangsal Aceh, Kota Dumai memiliki kapal berbentuk sampan yang memiliki tempat yang sempit. Tujuan dari pengabdian ini yaitu memberikan solusi berupa pelatihan penggunaan generator portable tenaga surya untuk sistem kelistrikan di kapal yang sempit. Metode pengumpulan data dalam menentukan ketercapaian keberhasilan kegiatan menggunakan skala likert. Kegiatan di lakukan dalam satu hari berupa materi teori dan praktik. Peserta sebelum diberikan materi diberikan pre-test. Sedangkan setelah materi selesai diberikan post-test dan kuesioner kepuasan sebagai instrument kegiatan tingkat keberhasilan. Berdasarkan analisa didapatkan hasil kenaikan pre-test dan post test seuai kategori yaitu Pengetahuan, 85,41%, Pengoperasian 95,75% dan Pengisian Energi 92,77 serta tingkat kepuasan peserta yaitu 69% Sangat Puas. Analisa ketercapaian dari kegiatan ini secara berturut-turut menurut kategori penyajian, dampak kegiatan dan kebermanfaatan kegiatan yaitu 92,4%; 91,7% dan 93,1%. Jika di rata-rata didapatkan nilai ketercapaian mendapatkan nilai 92,4%.
