Abstract

Injector adalah suatu alat untuk menyemprotkan bahan bakar minyak menjadi kabut halus atau gas yang akan mempermudah gas tersebut terbakar di dalam ruang bakar mesin. Proses pengabutan ini bertujuan agar bahan bakar mudah bercampur dengan udara dan terbakar secara sempurna di dalam ruang bakar mesin. Dengan lancarnya sirkulasi bahan bakar di dalam mesin maka akan berdampak pada efisiennya kinerja injector. Penelitian ini bertujuan untuk menyelidiki penyebab masalah injector pembakaran pada mesin diesel kapal KM Logistik Nusantara 4 dan merumuskan strategi pemeliharaan yang dapat menyelesaikan masalah tersebut secara efektif. Penelitian ini menggunakan metode reduksi data untuk menghilangkan materi-materi yang tidak perlu dan mengorganisasikan data sehingga dapat ditarik kesimpulan akhir, hasil akhir penelitian menunjukkan bahwa penyebab kerusakan injector disebabkan oleh terkontaminasi partikel asing dalam bahan bakar. Dengan itu diperlukan perawatan rutin seperti pembersihan injector dan filter secara berkala. Sehingga untuk mempertahankan kualitas injector bahan bakar di kapal, memperpanjang usia mesin kapal, dan meningkatkan efisiensi operasional kapal An injector is a device to spray fuel oil into a fine mist or gas that will make it easier for the gas to burn in the combustion chamber of the engine. This fogging process aims to make the fuel easily mix with the air and burn perfectly in the engine's combustion chamber. With the smooth circulation of fuel in the engine, it will have an impact on the efficiency of the injector performance. This study aims to investigate the cause of the combustion injector problem in the diesel engine of the KM Logistik Nusantara 4 ship and formulate a maintenance strategy that can solve the problem effectively. This study uses a data reduction method to eliminate unnecessary materials and organize the data so that a final conclusion can be drawn, the final results of the study show that the cause of the damage to the injector is caused by contamination of foreign particles in the fuel. With that, regular maintenance is required such as regular cleaning of injectors and filters. So as to maintain the quality of the fuel injector on the ship, extend the life of the ship's engine, and improve the operational efficiency of the ship

Abstract

Fresh Water Generator (FWG) adalah permesinan bantu di kapal yang mengubah air laut menjadi air tawar melalui proses destilasi, dengan ejector pump sebagai komponen utama untuk menciptakan tekanan vakum. Penelitian ini mengevaluasi kinerja ejector pump secara kualitatif melalui wawancara dengan operator kapal dan pengamatan langsung. Analisis dilakukan secara deskriptif serta didukung tinjauan dokumen teknis dan pedoman perawatan. Hasil penelitian menunjukkan bahwa performa ejector pump dipengaruhi oleh suhu dan salinitas air laut, kebersihan sistem perpipaan, serta efektivitas perawatan berkala. Masalah umum yang ditemukan meliputi penurunan tekanan vakum akibat kotoran dan kerusakan karena kavitasi. Operator kapal menekankan pentingnya inspeksi rutin dan perawatan terjadwal untuk menjaga performa optimal. Penelitian menyimpulkan bahwa pengelolaan ejector pump yang baik, melalui jadwal perawatan yang konsisten dan peningkatan keterampilan operator, dapat meningkatkan efisiensi sistem FWG dalam mendukung kebutuhan air tawar di kapal Fresh Water Generator (FWG) is an auxiliary machinery on ships that converts seawater into fresh water through a distillation process, with the ejector pump serving as a key component in creating a vacuum pressure. This study evaluates the performance of the ejector pump qualitatively through interviews with ship operators and direct observation. The analysis is conducted descriptively and supported by a review of technical documents and maintenance guidelines. The results indicate that the performance of the ejector pump is influenced by seawater temperature and salinity, the cleanliness of the piping system, and the effectiveness of regular maintenance. Common issues found include reduced vacuum pressure due to dirt buildup and damage caused by cavitation. Ship operators emphasize the importance of routine inspections and scheduled maintenance to maintain optimal performance. The study concludes that proper management of the ejector pump, through a consistent maintenance schedule and improved operator skills, can enhance the efficiency of the FWG system in supporting the ship's freshwater needs

Abstract

Turbocharger adalah alat bantu yang digerakkan oleh gas buang auxiliary diesel engine dan berfungsi memompa udara untuk proses pembilasan dan pembakaran di dalam silinder. Kinerja mesin ini sangat bergantung pada turbocharger. Kerusakan pada turbocharger, khususnya pada bearing, dapat menurunkan performa mesin secara signifikan. Penelitian ini bertujuan untuk mengidentifikasi penyebab kerusakan bearing turbocharger, dampaknya terhadap auxiliary engine, serta upaya perbaikannya di MV Armada Sejati. Metode yang digunakan adalah deskriptif kualitatif dengan pendekatan fishbone. Data dikumpulkan melalui observasi, wawancara, dan dokumentasi. Hasil penelitian menunjukkan bahwa kerusakan disebabkan oleh tercampurnya oli pelumas dengan gas buang, keausan sealing bush, dan tersumbatnya lubang oil pump. Dampaknya antara lain berkurangnya suplai udara, kerusakan ring piston, dan pembakaran yang tidak sempurna sehingga daya mesin menurun. Upaya pencegahan dilakukan dengan perawatan rutin turbocharger, penggantian komponen lama, serta pergantian oli pelumas secara berkala. A turbocharger is an auxiliary exhaust device that is driven by the auxiliary exhaust of a diesel engine and functions to pump air for the rinsing and combustion process inside the cylinder. The performance of this engine is highly dependent on the turbocharger. Damage to the turbocharger, especially to the bearings, can significantly degrade engine performance. This study aims to identify the cause of damage to the turbocharger bearing, its impact on the auxiliary engine, and its repair efforts in MV Armada Sejati. The method used is qualitative descriptive with a fishbone approach. Data was collected through observation, interviews, and documentation. The results of the study showed that the damage was caused by the mixing of lubricating oil with exhaust gases, the wear of the sealing bush, and the clogging of the oil pump holes. The impact includes reduced air supply, damage to the piston rings, and imperfect combustion so that engine power decreases. Prevention efforts are carried out with regular maintenance of turbochargers, replacement of old components, and periodic changes of lubricating oil

Abstract

Penelitian ini bertujuan untuk mengidentifikasi penyebab tidak optimalnya kinerja Fresh Water Maker (FWM) berteknologi Reverse Osmosis (RO) di kapal CTS. Bulk Java, serta dampaknya terhadap operasional kapal. Metode yang digunakan adalah pendekatan deskriptif kualitatif melalui observasi langsung, wawancara dengan engineer kapal, dan dokumentasi sistem. Hasil penelitian menunjukkan bahwa penurunan produksi air tawar dari 1.000 L/jam menjadi 800 L/jam disebabkan oleh kerusakan pada mechanical seal feed pump, umur filter yang telah melebihi batas kerja, serta kebocoran pada pipa membran. Kondisi ini berdampak pada kebutuhan harian kru kapal dan menambah biaya operasional karena perlunya pengisian air tawar dari darat. Upaya perbaikan mencakup penggantian komponen rusak seperti impeller, filter, dan perbaikan pipa. Setelah overhaul, FWM kembali beroperasi optimal. Penelitian ini merekomendasikan inspeksi dan perawatan berkala untuk menjaga kinerja sistem FWM RO secara berkelanjutan.   This study aims to identify the causes of the suboptimal performance of the Reverse Osmosis-based Fresh Water Maker (FWM) system on the CTS. Bulk Java ship and its impact on ship operations. The research uses a qualitative descriptive method through direct observation, interviews with ship engineers, and system documentation. The findings show that the decline in freshwater production from 1,000 L/hour to 800 L/hour was due to damage to the feed pump’s mechanical seal, expired filter life, and leaks in the membrane pipe. This condition disrupted crew water supply and increased operational costs due to the need for freshwater bunkering from the shore. Repairs included replacing damaged components such as the impeller and filters, and repairing the leaking pipe. After the overhaul, the FWM resumed optimal performance. The study recommends routine inspection and maintenance to sustain the reliability of the FWM RO system
