Abstract

Ships as an important means of transportation require the availability of good quality fresh water to meet the daily needs of the crew. Because the quality of fresh water that does not meet the standards can interfere with the activities of the crew. This research aims to build a water treatment system on board controlled by ATMEGA 2560 microcontroller. The system is equipped with turbidity sensor SEN0189, TDS sensor SEN0244, and PH sensor SEN0161 to monitor the freshwater quality. The process of working this tool by treating fresh water which then the parameters are detected by the PH sensor, TDS sensor, and turbidity sensor which then the detection results are displayed on the LCD monitor, and the buzzer and LED turn on when the condition of the fresh water parameters does not meet the standards. The methodology and design of this system will be carried out with experimental research methods where in this method at least one variable is manipulated to study the cause-and-effect relationship. The results of testing water treatment using ATMEGA 2560 show that the system can work optimally in treating fresh water. And the accuracy of the PH sensor, TDS sensor, and turbidity sensor is quite accurate with the difference in error with the comparison measuring instrument less than 5%.

Abstract

This study aims to analyze the suboptimal performance of hydraulic pump system on hatch cover performance on MV. Emerald Indah using USG (Urgency, Seriousness, Growth) method and data collection techniques in the form of observation, documents, and interview. The purpose of this study is to determine the causes, effect and efforts in solving the problems discussed. The results of the study indicate that several factors cause the hydraulic pump system to not function optimally , including dirty filters, leak in the hydraulic pump and pipe, and operation that is not in accordance with procedures. The effect of the suboptimal hydraulic pressure which ultimately becomes the main problem that inhibits the hatch cover opening process. To overcome this problem, improvements are needed such as periodic filter cleaning, replacement of leaking components, and increasing crew understanding of operational procedures. This research is expected to provide insight for related parties in improving the performanceof the hydraulic pump system and the efficiency of the loading and unloading process on ships.

Abstract

This study discusses the causes of leakage in cargo oil pumps, which play a crucial role in the discharge operation of tankers carrying oil, chemicals, and gas. Regular maintenance is essential to prevent damage that could hinder the ship's operations. The method used is descriptive qualitative, with data gathered from observations, interviews, documentation, and literature review. The analysis is conducted using Fishbone to identify the root causes of the problem. The results show that leakage occurs due to the misalignment of the pump shaft. This misalignment causes excessive vibration at high speeds, damaging components, especially the carbon seal face of the mechanical seal, leading to leakage of cargo. Preventive measures include regular and scheduled maintenance, proper lubrication, routine inspection while the pump is running, and alignment checks to ensure the shaft is straight. If any issues are found, repair or replacement with new parts is necessary to ensure the pump operates efficiently and the discharge process runs smoothly.
Pengaruh Kedisiplinan Kerja ABK Mesin Terhadap Kegiatan Dinas Jaga Guna Kelancaran Operasional Kamar Mesin: (Studi Kasus: KMP. Dharma Bahari Sumekar III) Nasution, Farika; Frenki Imanto; Maulidiah Rahmawati; Agus Prawoto; Shofa Dai Robbi

Abstract

Penelitian ini menganalisis pengaruh kedisiplinan kerja ABK mesin terhadap kegiatan dinas jaga dan dampaknya pada kelancaran operasional kamar mesin. Metode yang digunakan adalah kuantitatif deskriptif dengan analisis regresi linier. Data dikumpulkan melalui kuesioner yang mencakup variabel kedisiplinan kerja (X1) sebagai variabel bebas dan kegiatan dinas jaga (X2) sebagai variabel dependen/terikat, dan kelancaran operasional kamar mesin (Y) sebagai variabel terkontrol.  Maka variabel dapat disimpulkan menjadi X1→ X2 → Y. Sampel penelitian meliputi seluruh ABK bagian mesin, mulai dari chief engineer hingga engine cadet. Hasil uji validitas menunjukkan seluruh item valid dengan reliabilitas sangat tinggi (Cronbach’s Alpha > 0,98). Analisis deskriptif menunjukkan kedisiplinan ABK mesin berkategori baik, terutama pada aspek ketepatan waktu dan kepatuhan prosedur keselamatan. Analisis regresi menunjukkan koefisien pengaruh signifikan sebesar 0,821 (X1→ X2) dan 0,794 (X2 → Y). Indikator kelancaran operasional meliputi akurasi pencatatan parameter, keandalan alat bantu, dan respons cepat terhadap alarm. Temuan ini membuktikan disiplin ABK adalah faktor krusial untuk menjamin operasi kamar mesin yang aman dan efisien. Penelitian ini merekomendasikan peningkatan pelatihan kedisiplinan dan evaluasi rutin guna menjaga mutu operasional kapal.
