Abstract

INTISARI Aripin, 2020 “Analisis terjadinya kebocoran air pendingin di dalam ruang bakar main engine MV. Spil Hana” skripsi Program Studi Teknika, Program Diploma IV, Politeknik Ilmu Pelayaran Semarang, Pembimbing I: Nasri, M.T, M.Mar.E dan Pembimbing II: Sri Suyanti, S.S. Mesin induk merupakan mesin penggerak utama di kapal yang menjadi penggerak/pendorong kapal supaya kapal dapat berjalan maju atau mundur sesuai pengoperasian. Masuknya air pendingin ke dalam ruang bakar mempengaruhi kinerja mesin induk. Permasalahan tersebut diketahui saat akan melakukan test engine sebelum kapal melakukan manouver, mesin induk di blow up dan keluar air pendingin dari indicator valve silinder no. 1 mesin induk. Tujuan penelitian ini untuk mengetahui faktor apa yang menyebabkan masuknya air pendingin ke dalam ruang pembakaran mesin induk dan menentukan Upaya apa yang dilakukan untuk mengatasi masuknya air pendingin ke dalam ruang pembakaran mesin induk. Penulis merangkum permasalahanpermasalahan dan mencoba mengidentifikasi masalah dengan menggunakan metode fishbone analysis Ada banyak penyebab masuknya air pendingin ke dalam ruang pembakaran mesin induk silinder no.1 di kapal MV.Spil Hana. Penyebab utama masuknya air pendingin ke dalam ruang pembakaran silinder no 1 di MV. Spil Hana adalah keretakan dinding cylinder head, karena perawatan yang tidak sesuai dengan PMS dan kualitas air pendingin yang mempengaruhi sistem pendinginan yang menyebabkan kelelahan bahan cylinder head dan cylinder head mengalami keretakan yang mempengaruhi kinerja dari mesin induk. Untuk menangani masalah tersebut berdasarkan penelitian oleh penulis dapat dilakukan upaya perawatan dan penggantian spare part sesuai dengan PMS serta menjaga kualitas air pendingin untuk system pendinginan yang lebih baik. ABSTRACT Aripin, 2020 "Analysis of the occurrence of a cooling water leak in the combustion chamber of the main engine MV. Spil Hana ”thesis of Engineering Study Program, Diploma IV Program, Semarang Shipping Polytechnic, Advisor I: Nasri, M.T, M.Mar.E and Advisor II: Sri Suyanti, S.S. The main engine is the main driving machine on the ship which becomes the driving / driving of the ship so that the ship can go forward or backward according to operation. The entry of cooling water into the combustion chamber affects the performance of the main engine. The problem is known when going to test the engine before the ship maneuvers, the main engine is blown up and cooling water comes out of the cylinder indicator valve no. 1 main engine. The purpose of this study was to determine what factors caused cooling water to enter the combustion chamber of the main engine and determine what efforts were made to overcome the entry of cooling water into the combustion chamber of the main engine. The author summarizes the problems and tries to identify the problem using the fishbone analysis. There are many reasons for the entry of cooling water into the combustion chamber cylinder engine No. 1 on the MV.Spil Hana ship. The main cause of the entry of cooling water into the combustion chamber cylinder No. 1 in the MV. Spil Hana is a cylinder head wall crack, due to incompatible maintenance with PMS and cooling water quality that affects the cooling system which causes fatigue of the cylinder head and cylinder head material which has cracks which affects the performance of the main engine. To deal with these problems based on research by the author, efforts can be made to care and replace spare parts in accordance with PMS and maintain the quality of cooling water for a better cooling system.
