Abstract

Fuel serves as a crucial element in the operations of fishing businesses employing boats. Presently, the usage of fuel in ships remains significant, yet it lacks thorough mathematical and theoretical assessment. This research aims to evaluate, both mathematically and theoretically, the fuel consumption of fishing vessels during their fishing endeavors. The study involved observations of various aspects, such as engine types, fuel types, and fuel flow, on fishing vessels. Fuel consumption was computed based on operational hours and RPM (Revolutions Per Minute) of diesel engines onboard ships. The findings revealed that engines with identical loads exhibited varying fuel consumption rates due to differences in cylinder volume. Additionally, fuel consumption increased with higher RPM. Fluctuations in fuel consumption during fishing operations were attributed to adjustments made by vessels according to environmental and situational factors. Theoretical and mathematical analyses indicated that several factors, including operational hours, RPM, and cylinder volume, influence fuel consumption in diesel engines of fishing vessels. This study's significance lies in providing insights into the theoretical and mathematical aspects of predicting fuel consumption in diesel engines utilized in fishing vessels.

Abstract

Refrigeration machines in fishery companies are widely used to maintain the quality of seafood products to keep them fresh. These machines are quite complex, so operating them correctly is crucial, as fatal operational errors can lead to the damage of the refrigeration equipment. The absence of written SOPs has the potential for non-standardized operations. Therefore, this article aims to develop Standard Operating Procedures (SOPs) for operating refrigeration machines on fishing vessels. To achieve this goal, data from the refrigeration system is used, and competent machine crew members are involved to obtain valid data. The data obtained is analyzed using a quantitative descriptive method. A proposed design of Standard Operating Procedure (SOP) with a cross-functional flow chart diagram has been produced as a guideline for operating refrigeration machines on fishing vessels. Based on the analysis, this SOP Draft has met the eligibility criteria for use. The SOP this machinery are highly significant in assisting the machine crew in ensuring that the machines are operated in a controlled manner following the correct procedures.

Abstract

Numerous studies have been conducted on voltage and current imbalance in three-phase electrical installations, but there has been no research specifically analyzing the correlation between voltage and current imbalances in the electric generators of fishing vessels. This study aims to investigate and analyze potential relationships among four key variables within this research context: apparent power, generator loading percentage, voltage imbalance, and current imbalance aboard KM. Sumber Mandiri.The research findings reveal the Pearson correlation coefficient value indicating the average generator loading percentage's correlation with the average current imbalance to be only 2.47%. Additionally, the average apparent power's Pearson correlation coefficient with the average current imbalance on the KM. Sumber Mandiri generator between November 17, 2022, and November 26, 2022, is calculated to be 0.29%. Moreover, the average generator loading percentage's Pearson correlation coefficient with the average voltage imbalance stands at 27.58%, while the average apparent power's Pearson correlation coefficient with the average voltage imbalance is at 40.91%. The fluctuations in current imbalance in relation to the variation in voltage imbalance on the KM. Sumber Mandiri generator show an impact of 14.03%, while the remaining 85.97% is attributed to other factors. The outcomes of this research are expected to provide valuable insights into the understanding of factors influencing voltage and current imbalance from a statistical perspective. Additionally, this study may assist in enhancing and designing more efficient and reliable electrical systems in three-phase installations aboard KM. Sumber Mandiri.
PENINGKATAN KOMPETENSI PERMESINAN MELALUI PEMBELAJARAN PRAKTIK PADA SISWA SMK PERIKANAN PROVINSI RIAU Yaqin, Rizqi Ilmal; Demeianto, Bobby; Siahaan, Juniawan Preston; Abrori, M. Zaki Latif; Tumpu, Mula; Priharanto, Yuniar Endri; Lagsmana, Tegar

Abstract

Penggunaan peralatan praktik dalam proses pembelajaran sangat penting teurtama dalam peningkatan kompentensi bagi siswa. Namun beberapa sekolah menengah masih banyak sarana dan prasaran yang belum mencukupi untuk kegiatan pembelajaran praktik. Oleh karena itu, tujuan pengabdian kepada masyarakat ini yaitu meningkatkan kompetensi dan kebermanfaatan kegiatan pembelajaran praktik dari segi dampak kegiatan bagi siswa SMK Perikanan Provinsi Riau. Kegiatan dipersiapkan dengan penentuan lokasi yang akan digunakan dan menyesuaikan dari jadwal kegiatan. Dalam mengolah dan memporeleh data dilakukan kegiatan pengisian kuesioner tingkat kepuasan dan tingkat ketercapaian kegiatan. Analisa data menggunakan metode skala linkert. Hasil analisa akan menentukan ketercapaian kegiatan berdasarkan nilai persentase yang didapatkan dari analisa skala linkert. Hasil diperoleh yaitu kegiatan berjalan dengan lancar dengan beberapa materi yang diajarkan secara teori dan praktek. Tingkat kepuasan peserta yaitu 72% sangat puas dan 28% puas. Sedangkan tingkat ketercapaian kegiatan berdsarkan kategori penyajian, dampak kegiatan dan kebermanfaatan secara berturut-turut yaitu 90,1%, 93,2% dan 95,3%. Berdasarakan hasil tersebut maka dapat dikatakan kegiatan pengabdian kepada masyarakat sebagian besar tercapai. Sehingga dapat berkontribusi dalam peningkatan kompetensi permesinan pada siswa SMK Perikanan Provinsi Riau.
