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.

Abstract

Enclosed spaces in ship engine rooms pose significant risks due to toxic gas accumulation like carbon monoxide and carbon dioxide, contributing to maritime fatalities. This research aimed to develop a Wemos D1-based prototype for real-time hazardous gas detection to enhance crew safety on MT Plaju tanker. Experimental prototype development employed ADDIE model with static and dynamic testing on MQ-135 sensor, buzzer, LED, and WiFi web monitoring. Population comprised four main holes (A-D) in engine room enclosed spaces, sampled through 20 measurements during 12-month sea practice. Instruments included Arduino IDE for programming and Excel for regression linear analysis with <5% calibration error. Results showed average CO detection at 5.4 ppm and CO2 at 406 ppm, with alarm response under 6 seconds exceeding 30% threshold, achieving 95% accuracy in high humidity and vibration conditions. The prototype demonstrated superior WiFi connectivity over previous ATMega328P systems, reducing hazard zones by 40%. In conclusion, this cost-effective IoT solution validates hardware reliability for Indonesian maritime operations, recommending multi-gas sensor integration for industrial scaling.

Abstract

Maritime safety demands innovative solutions amid rising engine room accidents from non-compliance with personal protective equipment like safety helmets, contributing 15-20% of global incidents. This study aimed to design and build an Arduino Pro Micro-based helmet detection system using micro switches and buzzers for real-time alerts in harsh ship environments. Employing a Research and Development (R&D) approach with ADDIE model, the prototype was tested on 10 engine crew (ABK) aboard KMP JAMBO IX via purposive sampling. Instruments included Arduino IDE for programming, serial monitors for data logging, and SPSS 26 for t-test analysis (p<0.05). Results showed 100% micro switch accuracy, 15-second buzzer response, and 7-hour battery life across four tests, reducing SOP violations from observed pre-implementation lapses. In conclusion, the system enhances crew discipline and supervision efficiency, bridging gaps in affordable maritime IoT safety tools, with potential to cut head injuries by 20-30%.

Abstract

Human resource management in ship engine rooms faces challenges such as low productivity and high turnover due to the ineffective leadership style of the chief engineer. This study aims to analyze the influence of the chief engineer's leadership style on the performance of crew members (ABK) in the engine room. Using a quantitative explanatory approach with a descriptive survey design, the population includes all crew members in the engine room of the marine practice ship Polytechnic of Shipping Surabaya, with a sample of 35 respondents through purposive sampling. The Likert scale questionnaire instrument (1-5) was analyzed using SPSS for descriptive statistics, validity/reliability tests, simple linear regression, t-test, and R². The results showed a significant positive effect (t-count 5.370 > t-table 2.034; sig. 0.000), with R² 0.450 which means leadership explains 45% of the performance variation. The conclusion states that chief engineers need to implement proactive leadership to improve shipping efficiency and safety.

Abstract

: Air compressors serve as vital auxiliary engines on ships for starting main engines and operating valves, yet manual monitoring leads to inefficiencies and frequent failures, contributing to 20% of machinery downtimes globally. This study aims to design and build a prototype air compressor with ESP32-based microcontroller monitoring system for real-time electrical parameter tracking. Employing an experimental prototype development design, the research utilized laboratory-scale prototype as subject, with hardware including PZEM-004T sensor, LCD I2C, and Blynk app; data analyzed via comparative quantitative measurements against standard multimeter for accuracy assessment. Results demonstrate 100% consistency in voltage (230V), current (6.1A), power (1015W), and frequency (50Hz) readings across LCD and remote app during static/dynamic tests. In conclusion, the prototype enhances predictive maintenance and educational training for maritime students, although field testing in harsh conditions is recommended
