Abstract

Proses pengabutan bahan bakar pada Injector mesin induk kapal sangat menentukan efisiensi pembakaran. Ketidaksempurnaan proses ini dapat disebabkan oleh tekanan bahan bakar rendah, penyumbatan nozzle, atau kualitas bahan bakar buruk. Penelitian ini dilakukan di kapal MV. SPIL RUMI untuk menganalisis penyebab dan solusi dari ketidaksempurnaan tersebut. Penelitian ini menggunakan pendekatan kualitatif dengan metode observasi langsung, wawancara, dan dokumentasi selama praktik laut di MV. SPIL RUMI. Teknik analisis menggunakan diagram fishbone untuk menemukan penyebab utama permasalahan pengabutan bahan bakar, dengan mempertimbangkan faktor manusia, material, metode, dan mesin secara sistematis dan mendalam. Ditemukan bahwa ketidaksempurnaan pengabutan disebabkan oleh tekanan bahan bakar rendah, penyumbatan nozzle, filter kotor, kualitas bahan bakar buruk, serta purifier yang tidak optimal. Setelah dilakukan perbaikan dan pengujian tekanan, performa Injector kembali normal. Perawatan rutin dan prosedur sesuai manual book menjadi solusi utama untuk mencegah kerusakan serupa. Ketidaksempurnaan pengabutan terjadi akibat tekanan tidak maksimal, penyumbatan nozzle, kualitas bahan bakar rendah, dan filter atau purifier yang tidak terawat. Pencegahan dilakukan melalui perawatan Injector, pengecekan tekanan, penggunaan bahan bakar standar, serta perawatan sistem filtrasi. Perawatan berkala menjamin pembakaran sempurna dan efisiensi mesin yang optimal.   The fuel fogging process in the main ship engine injector greatly determines the combustion efficiency. This process imperfection can be caused by low fuel pressure, nozzle blockage, or poor fuel quality. This research was conducted on the MV. SPIL RUMI to analyze the causes and solutions of such imperfections. This study uses a qualitative approach with direct observation, interviews, and documentation methods during marine practice at MV. SPIL RUMI. The analysis technique uses fishbone diagrams to find the main causes of fuel fogging problems, taking into account human, material, method, and machine factors systematically and deeply. It was found that fogging imperfections were caused by low fuel pressure, nozzle clogging, dirty filters, poor fuel quality, and suboptimal purifiers. After repairs and pressure tests, the Injector's performance returned to normal. Regular maintenance and manual procedures are the main solution to prevent similar damage. Fogging imperfections occur due to suboptimal pressure, nozzle blockage, low fuel quality, and unmaintained filters or purifiers. Prevention is carried out through injector treatment, pressure checking, standard fuel use, and filtration system maintenance. Periodic maintenance guarantees perfect combustion and optimum engine efficiency
