Abstract

Sea transportation accounts for 3% of the global greenhouse gas effect. The International Maritime Organization (IMO) is committed to reducing the impact of greenhouse gases by 50% in 2050—Indonesia is a maritime country with 10.8% of the world's ship register. High traffic has an impact on increased gas emissions. The IMO has made a policy on the Ship Energy Efficiency Management Plan. IMO recommends using Shore Side Electricity to reduce exhaust emissions, namely the use of electricity sources from land will reduce the operation of the ship's generator when berthing.This SSE case study uses the State Ship (KN) Masalembo at the Tanjung Perak Port. Evaluation of the impact of SSE on emission reduction is carried out by calculating electricity and fuel consumption. Based on fuel consumption, the amount of pollutants produced is known. A Descriptive quantitative method is used in this research. Based on the calculation, the electricity demand at 220 Volt voltage is 95,028 watts, and at 380 watts is 276,210 Watts. There are 3 generators on board with different output power. There are: auxiliary engine 1-2, harbour generator, and emergency generator. Each generator has different efficiency and fuel consumption. The Comparison of SSE reduction impact is largest in aux eng 1-2 worth 206,855.13 kg pollutant/ton of fuel. Fuel cost savings of up to 92.57% every year. SSE utilization is a solution for reducing exhaust emissions in the port area. Power generation using renewable energy sources is a recommendation for supporting SSE operations.

Abstract

 Intercooler berfungsi untuk mendinginkan udara yang akan masuk ke ruang bakar mesin, udara dari turbocharger di dinginkan sebelum masuk ke ruang bakar. Mesin induk sering mengalami kenaikan suhu ketika penulis melakukan penelitian pada saat kapal melakukan anchore job di Laut natuna. Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan teknik analisis metode RCA (Root Cause Analisis). Tujuan dari penelitian kualitatif adalah untuk menjelaskan fenomena dengan seakurat mungkin melalui teknik pengumpulan data metode RCA (Root Cause Analisis), dengan data uji yang dilakukan dapat diketahui penyebab, dampak yang ditimbulkan, serta mengetahui upaya yang dapat dilakukan ketika mengalami troubleshooting. Penelitian ini menunjukkan menurunnya kinerja intercooler disebabkan oleh beberapa faktor, seperti kisi-kisi intercoller yang tersumbat dan pendinginan air tawar yang tidak maksimal yang disebabkan oleh L.T exchanger bermasalah. Dampak yang ditimbulkan adalah kenaikan suhu gas buang dan munculnya alarm pada indikator. Perawatan dan perbaikan yang dilakukan untuk mengatasi penyebab menurunnya kinerja intercooler yaitu melakukan Cleaning pada kisi-kisi intercooler dan pipa air tawar serta melakukan perawatan rutin pada intercooler.
