Abstract

Kompresor udara merupakan mesin bantu yang sangat penting dalam sistem permesinan kapal, khususnya dalam proses starting main engine yang membutuhkan tekanan udara tinggi. Penelitian ini bertujuan untuk menganalisis penyebab kerusakan piston pada kompresor udara type Hatlapa Hamworthy V-Line 150 dan dampak yang ditimbulkan terhadap operasional kapal. Metode penelitian yang digunakan adalah kualitatif, dengan teknik pengumpulan data melalui observasi langsung di atas kapal MT. Prima Lautan II, wawancara dengan perwira mesin (KKM, Masinis 2, dan Masinis 3), serta dokumentasi lapangan. Hasil penelitian menunjukkan bahwa penyebab utama kerusakan piston adalah tersumbatnya intercooler akibat korosi dan kotoran, kualitas pelumas yang menurun karena melebihi jam kerja (running hours), serta pemakaian material piston yang telah melewati batas jam kerja yang ditentukan. Dampak dari kerusakan ini adalah terganggunya sistem udara, kegagalan start main engine, dan menurunnya efisiensi operasional kapal. Analisis dilakukan menggunakan metode fishbone untuk mengidentifikasi akar permasalahan. Hasil penelitian ini menekankan pentingnya pemeliharaan rutin, penggantian suku cadang sesuai manual book, dan peningkatan kesadaran kru kapal terhadap pentingnya perawatan sistem udara.   The air compressor is a very important auxiliary engine in the ship's engine system, especially in the process of starting the main engine which requires high air pressure. This study aims to analyze the cause of piston damage in the Hatlapa Hamworthy V-Line 150 type air compressor and the impact it has on ship operations. The research method used is qualitative, with data collection techniques through direct observation on board the MT ship. Prima Lautan II, interviews with mechanical officers (KKM, Machinist 2, and Machinis 3), as well as field documentation. The results of the study show that the main cause of piston damage is intercooler clogging due to corrosion and dirt, decreased lubricant quality due to exceeding running hours, and the use of piston materials that have exceeded the specified working hour limit. The impact of this damage is the disruption of the air system, the failure of the main engine start, and the decline in the ship's operational efficiency. The analysis was carried out using the fishbone method to identify the root of the problem. The results of this study emphasized the importance of routine maintenance, replacement of spare parts according to the manual, and increased awareness of the ship's crew on the importance of air system maintenance.

Abstract

This study investigates the influence of psychological well-being and workplace well-being on the mental health of Indonesian seafarers by examining both factors within a single model in the maritime work context. This approach provides a broader understanding of how personal psychological resources and workplace conditions are associated with mental health outcomes. Using a quantitative approach, data were collected from 124 active Indonesian seafarers through three validated instruments: the Depression Anxiety Stress Scale (DASS-42), the Workplace Well-Being Index (WWBI), and Ryff’s Psychological Well-Being Scale. Multiple linear regression analysis showed that psychological well-being (β = -1.126, p < 0.001) and workplace well-being (β = -0.475, p = 0.021) were significant predictors of psychological distress. Psychological well-being contributed 14.22 percent and workplace well-being contributed 6.17 percent to the explained variance, while both variables jointly accounted for 20.4 percent of the variation in psychological distress. Higher levels of psychological well-being and workplace well-being were associated with lower levels of depression, anxiety, and stress among seafarers. These findings highlight the importance of both individual psychological resources and workplace conditions in supporting seafarers’ mental health. The results suggest that efforts to improve mental health in the maritime sector should focus not only on strengthening psychological well-being but also on promoting supportive workplace environments.
