Abstract

Pengabdian kepada Masyarakat ini bertujuan untuk merancang dan mengimplementasikan model pelatihan berbasis kompetensi guna meningkatkan kemampuan nelayan dalam melakukan perawatan berkala mesin perahu. Pelatihan difokuskan pada Masyarakat Nelayan Keputih Timur, Gang Pompa Air, Kelurahan Keputih, Kecamatan Sukolilo, Surabaya, yang mayoritas menggunakan mesin perahu sebagai alat utama operasional. Metode Pengabdian kepada Masyarakat menggunakan pendekatan kuantitatif dengan desain pra-eksperimen melalui pre-test dan post-test terhadap 30 peserta. Hasil pre-test menunjukkan bahwa hanya 20% nelayan memahami prosedur perawatan dasar mesin perahu. Setelah pelatihan dilakukan, hasil post-test menunjukkan peningkatan signifikan, di mana 83,3% peserta mencapai kategori kompeten dalam pengenalan komponen, penggantian oli, pengecekan sistem pendingin, serta penanganan gangguan ringan. Rata-rata skor pengetahuan teknis meningkat dari 48,2 menjadi 81,6 poin. Model pelatihan menggunakan pendekatan demonstratif, praktik langsung, dan modul bergambar sederhana berbasis lokalitas. Dapat disimpulkan bahwa pelatihan berbasis kompetensi secara signifikan meningkatkan keterampilan teknis nelayan dalam merawat mesin perahu, yang berdampak pada efisiensi kerja dan penurunan biaya perbaikan rutin. Pengabdian kepada Masyarakat ini merekomendasikan penguatan pelatihan lanjutan secara berkala serta sinergi antara lembaga pendidikan vokasi dan kelompok nelayan setempat untuk keberlanjutan program.

Abstract

This study aims to identify the causes of sea water cooling pump failure, analyze its impact on the main engine cooling system, and explain the corrective actions taken to restore pump performance on board MV. Manalagi Wanda. The sea water cooling pump is one of the essential auxiliary machines responsible for circulating seawater as a cooling medium to maintain the main engine operating temperature within a safe range during ship operations. This research employed a descriptive qualitative method with data collected through direct observation, interviews with the Chief Engineer, Fourth Engineer, and Foreman, as well as documentation during the sea practice period. The collected data were analyzed to determine the relationship between pump component failures and the decline in the performance of the main engine cooling system. The findings revealed that the pump pressure decreased from 2.4 bar to 1.4 bar, causing the main engine High Temperature (HT) to rise from 80.5°C to 82.5°C. Inspection and dismantling of the pump identified damage to the mechanical seal, bearing, and shaft. These damaged components resulted in leakage, excessive vibration, unstable pump rotation, and reduced seawater flow rate. Corrective maintenance was carried out by replacing the damaged components with new parts according to the manufacturer's specifications. After reassembly and a successful test run, the pump pressure returned to 2.4 bar, while the HT temperature decreased to approximately 80.0°C, allowing the cooling system to operate normally and efficiently once again.

Abstract

Sea water cooling pump is a vital component of the main engine cooling system, responsible for circulating seawater to absorb engine heat. Damage to Sea water cooling pump No. 2 on MV. Sjw Mountain reduced pump pressure from the normal range of 3.5–3.9 bar to 1.5–1.9 bar, causing the cooling system temperature to increase to 80°C and increasing the risk of engine overheating. This study aimed to identify the causes of pump failure, evaluate the level of failure risk, and determine appropriate corrective actions. The research employed the Fishbone diagram and Failure Mode and Effect Analysis (FMEA). Data were collected through observations, interviews with ship engineers, documentation, and questionnaires administered to the Chief Engineer, Second Engineer, Third Engineer , Fourth Engineer, and Oiler. The Fishbone analysis identified five contributing factors: man, method, machine, material, and environment. FMEA results showed that the method factor had the highest Risk Priority Number (RPN) of 210, followed by environment (175), machine (160), material (120), and man (100). The study concluded that inadequate inspection and maintenance practices were the primary causes of pump failure. Recommended improvements include strengthening the Planned Maintenance System (PMS), conducting regular inspections, replacing worn components, and improving crew supervision to maintain optimal cooling system performance.

Abstract

This study aims to analyze the factors causing the increase in fresh water cooling temperature in the Main Engine, the impacts on engine performance, and the corrective actions taken to overcome Cooling System problems on board Harbour Tug (HT) Kresna 3116. The research was conducted during the sea practice period (PRALA) from October 5, 2024, to October 5, 2025, using a descriptive qualitative research method. Data were collected through direct observation in the engine room, interviews with the Chief Engineer and engine crew, documentation, and analysis of Cooling System operational data. The results showed that the increase in fresh water cooling temperature from the normal condition of 70°C to 85°C was caused by several factors, including blockage of the Sea Chest due to mud and marine debris, scale accumulation in the fresh water cooler, damage to the Mechanical Seal of the Fresh Water Pump, and the less-than optimal implementation of the Planned Maintenance System (PMS). These problems reduced the effectiveness of the heat transfer process, causing the exhaust gas temperature to increase up to 460°C, decreasing combustion efficiency, increasing fuel consumption, and potentially leading to Overheating of the Main Engine. To address these issues, several corrective actions were implemented, including cleaning the Sea Chest and fresh water cooler, replacing the damaged Mechanical Seal on the Fresh Water Pump, renewing the Coolant, and carrying out PMS activities regularly and continuously. After these corrective measures were taken, the fresh water cooling temperature returned to its normal range of approximately 70°C, and the system pressure returned to 2.5 bar. Based on the research findings, it can be concluded that regular maintenance and monitoring of the Cooling System are essential to maintain Main Engine performance, improve vessel operational reliability, and prevent disruptions that could hinder sailing operations.

Abstract

This study analyzes the causes of piston lubrication system failure and its impact on the performance of Diesel Generator No. 1 aboard MV. Hanglima. The lubrication system is essential for reducing friction, cooling engine components, and preventing wear to ensure reliable diesel engine operation. This research employed a qualitative descriptive approach using direct observation in the engine room, interviews with engine crew members, and documentation from engine logbooks and engine disassembly results. The findings show that the engine initially operated normally, but a significant increase in fresh water and lubricating oil temperatures, followed by a drop in lubricating oil pressure below the minimum operating limit of 2.5 bar, activated the Low Lubricating Oil Pressure alarm. This condition caused the engine speed to decrease from 1200 RPM to approximately 700 RPM, reducing both frequency and electrical power output. Engine disassembly revealed that the failure was primarily caused by a blocked piston cooling jet in Cylinder No. 3, contaminated oil filters, sludge accumulation in the oil sump, and wear on the piston and cylinder liner. Regular preventive maintenance is therefore essential to ensure stable and reliable diesel generator performance.
