Abstract

Sistem bahan bakar (fuel oil) pada kapal memegang peranan penting dalam menjamin kelancaran suplai energi ke mesin utama. Efisiensi dari sistem ini sangat dipengaruhi oleh pemilihan pompa yang tepat serta desain perpipaan yang akurat. Pada kenyataannya, sering ditemukan penggunaan pompa dengan daya melebihi kebutuhan aktual akibat keterbatasan data lapangan dan metode estimasi konvensional, sehingga menyebabkan pemborosan energi dan biaya operasional. Penelitian ini bertujuan untuk menganalisis dan mengoptimalkan pemilihan pompa serta desain sistem perpipaan bahan bakar pada kapal Pinisi 50 meter dengan pendekatan permodelan 3D dan perhitungan. Metode yang digunakan meliputi evaluasi lapangan, pemodelan sistem perpipaan 3D menggunakan perangkat lunak AutoCAD, dan perhitungan head loss dengan persamaan Darcy-Weisbach sesuai regulasi BKI Volume III. Hasil penelitian menunjukkan kebutuhan daya pompa sebesar 0,30 kW, sedangkan pompa yang dipilih memiliki daya 0,75 kW. Rekomendasi pompa yang sesuai adalah centrifugal pump Ebara CDXM 70/10. Analisis ini menegaskan pentingnya optimasi pemilihan pompa untuk meningkatkan efisiensi energi dan menekan biaya operasional kapal. Penelitian ini berhasil mengoptimalkan pemilihan daya pompa sistem bahan bakar pada kapal Pinisi 50 meter. Pompa yang sebelumnya terpasang memiliki daya 1,2 kW, sedangkan hasil analisis kebutuhan daya teoritis sebesar 0,30 kW. Setelah perhitungan, direkomendasikan penggunaan pompa Ebara CDXM 70/10 dengan daya 0,75 kW. Penggantian ini mengurangi daya terpasang sebesar 37,5%, memberikan potensi penghematan energi dan peningkatan efisiensi yang signifikan. Namun, daya pompa terpilih masih lebih besar dari kebutuhan teoritis, sehingga evaluasi lanjutan tetap diperlukan untuk mencapai efisiensi energi optimal dan pengurangan biaya operasional jangka panjang. The fuel oil system on a ship plays a crucial role in ensuring a continuous energy supply to the main engine. The efficiency of this system is heavily influenced by proper pump selection and accurate piping design. In practice, pumps with power ratings exceeding actual requirements are often used due to limited field data and conventional estimation methods, leading to energy waste and increased operational costs. This study aims to analyze and optimize pump selection and fuel oil piping system design on a 50-meter Pinisi ship through a 3D modeling and analytical approach. The methods used include field evaluation, 3D piping system modeling using AutoCAD software, and head loss calculation based on the Darcy-Weisbach equation in accordance with BKI Volume III regulations. The results of the study show a required pump power of 0.30 kW, while the selected pump has a power of 0.75 kW. The recommended pump is a centrifugal pump, Ebara CDXM 70/10. This analysis emphasizes the importance of optimizing pump selection to improve energy efficiency and reduce ship operating costs. The study successfully optimized the fuel oil system pump power selection for the 50-meter Pinisi ship. The previously installed pump had a power of 1.2 kW, while the theoretical power requirement was calculated at 0.30 kW. Following the analysis, the recommended replacement pump is the Ebara CDXM 70/10 with a power rating of 0.75 kW. This replacement reduces the installed power by 37.5%, offering significant potential for energy savings and improved efficiency. However, the selected pump power is still higher than the theoretical requirement, indicating that further evaluation is needed to achieve optimal energy efficiency and long-term operational cost reduction.
