Abstract

Purifier diatas kapal berfungsi sebagai alat untuk memisahkan zat cair dengan air, kotoran dan endapan lumpur yang ada didalam sump tank atau setlink tank yang kebawa masuk kedalam purifier, lubricating oil purifier berfungsi untuk memisahkan oli dengan kotoran atau endapan yang ada didalam sumpt tank. dengan menggunakan gaya sentrifugal yang kecepatan tinggi yang dirancang khusus untuk melakukan proses purifikasi minyak lumas dari kotoran (sludge) atau air sehingga minyak lumas dapat dibersihkan dengan optimal. Lubricating oil Purifier memiliki peran penting dalam memastikan kelancaran pelumasan, karena kualitas pelumasan yang buruk pada mesin dapat menyebabkan penurunan kinerja mesin induk. Hal ini berpotensi menyebabkan kerusakan pada mesin induk, yang pada akhirnya dapat mengganggu kelancaran operasional kapal. Bagian paling penting dari purifier adalah main seal ring, fungsi dari main seal ring adalah untuk menutup rapat antara main cylinder dengan bowl hood dalam mencegah terjadi overflow minyak lumas. Tujuan dari penelitian ini yaitu untuk mengetahui penyebab pengaruh kualitas main seal ring terhadap kinerja purifier dalam mencegah overflow lubricating oil pada purifier. Menggunakan metode kualitatif dengan analisis data SHEL dalam mencegah terjadinya overflow lubricating oil pada purifier. Teknik pengumpulan data dengan melakukan wawancara bersama para Masinis dan engine crew dan observasi langsung kelapangan untuk mengetahui pengaruh kualitas main seal ring dalam mencegah overflow lubricating oil pada purifier. Dari hasil identifikasi, peneliti menemukan kotornya oli yang masuk purifier yang menyebabkan gesekan yang mengakibatkan aus, dimana main seal ring yang aus tidak dapat menutup celah antara main cylinder dan bowl hood sehingga oli bersih keluar ke sludge port atau intermediate tank. Masinis ataupun crew mesin yang sedang tugas jaga harus selalu melakukan pengecekan terhadap tanki intermediate lubricating oil purifier dan melakukan maintenance sesuai dengan jam kerja. Agar tidak terjadi kerusakan pada main seal ring yang menyebabkan overflow lubricating oil pada purifier lagi, operasional mesin induk juga lancar dan tidak merugikan berbagai pihak.

Abstract

Vocational education plays a strategic role in preparing a skilled workforce for both industry and entrepreneurship. However, many vocational school graduates face challenges in launching their own businesses due to insufficient entrepreneurial competencies. This study explores effective strategies for cultivating an entrepreneurial mindset among students at SMK Siang Surabaya. A qualitative research approach was employed, incorporating interviews, observations, and literature review. The findings reveal that integrating entrepreneurship education into the curriculum, offering business skills training, and implementing internship programs significantly enhance students' interest in and preparedness for entrepreneurship. The study underscores the value of a comprehensive support system, including mentorship, access to seed funding, and partnerships with local business practitioners, in addressing common obstacles such as low self-confidence, limited marketing knowledge, and financial constraints. These results provide actionable insights for vocational schools, educators, and policymakers in developing entrepreneurship-oriented educational strategies. By identifying key success factors, this research contributes to the advancement of vocational education and the promotion of sustainable youth entrepreneurship.

Abstract

The MT Anggraini Excellent ship was sailing from Balikpapan to Samarinda when an alarm sounded during the watch. The main engine jacket cooling system indicated a high temperature of 88º C. Measures were taken to reduce the rpm (slowhead) and report the condition of the main engine. A request was made to stop the engine to inspect the cooling system. Using a qualitative descriptive method, data was collected through observations, temperature readings, pressure measurements, maintenance records, and interviews. The factors causing and the impacts of the seawater pump failure were identified. Maintenance and repair actions for the seawater pump were implemented to support the operation of the main engine. The collected data will be analyzed using the fishbone approach and processed with triangulation techniques to identify the factors causing the seawater pump electromotor failure and address overheating in the main engine. The research results indicate that the cause of bearing damage is exceeding the running hours limit of 2,750 hours, with an average insulation test on the electromotor of 10MΩ, and a decrease in pump pressure of 1.5 kg/cm² from the normal condition of 3 kg/cm² due to mechanical seal damage and a dirty seachest. The bearings, the three-phase 60 Hz 440 V 55 kW electric motor, and the mechanical seal were replaced. It is recommended to perform regular maintenance on the electric motor and pump in accordance with the PMS (Plan Maintenance System). Ensuring the availability of spare parts, electric motors, and seawater pumps is essential to maintain operational efficiency during maintenance.

Abstract

When MV. Kartini Samudra was anchored in Kalimantan for the loading process, an abnormal sound was detected in diesel generator no. 3. A decision was made to conduct periodic inspections of the camshaft of diesel generator no. 3, which revealed erosion damage. Consequently, the workload was transferred to diesel generator no. 2 to allow for further examination of diesel generator no. 3's camshaft. This study aims to identify the factors contributing to camshaft damage in the diesel generator, assess the resulting impacts, and propose preventive measures. Employing qualitative methods through case study analysis, data were collected via observations, interviews, and documentation. Visual comparisons of exhaust gases and jacket cooling temperatures were processed using triangulation techniques. The analysis utilized fishbone and 5W methods. The findings indicate that the camshaft damage was due to valve gap conditions exceeding 1.5mm, contamination of lubricating oil with a significant amount of iron particles, and prolonged running hours. Notable symptoms included thick black exhaust gas and a jacket cooling temperature of 55°C, which is below the optimal 70°C. The impact of the camshaft damage necessitates measures such as regular checking and adjustment of valve gaps to between 0.6mm and 1.0mm, and timely oil changes in accordance with the planned maintenance schedule. Ketika MV. Kartini Samudra sedang berlabuh di Kalimantan untuk proses pemuatan, terdeteksi suara tidak normal pada genset diesel no. 3. Keputusan diambil untuk melakukan pemeriksaan berkala terhadap camshaft genset diesel no. 3, yang mengungkap adanya kerusakan berupa erosi. Akibatnya, beban kerja dialihkan ke genset diesel no. 2 untuk memungkinkan pemeriksaan lebih lanjut pada camshaft genset diesel no. 3. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang berkontribusi terhadap kerusakan camshaft pada genset diesel, mengkaji dampak yang ditimbulkan, serta mengusulkan tindakan pencegahan. Metode kualitatif digunakan melalui analisis studi kasus, dengan data yang dikumpulkan melalui observasi, wawancara, dan dokumentasi. Perbandingan visual gas buang dan suhu pendinginan jaket diproses menggunakan teknik triangulasi. Analisis dilakukan dengan menggunakan metode fishbone dan 5W. Temuan penelitian menunjukkan bahwa kerusakan camshaft disebabkan oleh kondisi celah katup yang melebihi 1,5 mm, kontaminasi oli pelumas dengan partikel besi dalam jumlah besar, dan jam operasi yang berkepanjangan. Gejala yang menonjol termasuk gas buang berwarna hitam pekat dan suhu pendingin jaket 55°C, yang berada di bawah suhu optimal 70°C. Dampak kerusakan camshaft ini memerlukan tindakan pencegahan seperti pemeriksaan rutin dan penyesuaian celah katup antara 0,6 mm hingga 1,0 mm, serta penggantian oli secara tepat waktu sesuai dengan jadwal perawatan yang direncanakan.
