MT. Capibara is equipped with the BalClor® Ballast Water Management System (BWMS), which utilizes the electrochlorination method in the ballast water treatment process. Based on the observations, the TRO Analyzer displayed a reading of 6.27 mg/L during the verification process prior to de-ballasting at Tuapse Port, Black Sea. This study aims to identify the factors affecting BWTS operation and the efforts that can be undertaken to support the effectiveness of System operation. The research employed a qualitative descriptive method. Data were collected through observation, interviews, documentation, and literature review during the sea practice period on board MT. Capibara. Data analysis was conducted using the Fishbone Analysis method to identify factors influencing BWTS operation based on the aspects of Machine, man, method, and Environment. The results indicate that BWTS operation is influenced by several factors, including the performance of the TRO Analyzer, the condition of the chlorine buffer solution, the performance of the Oxidant Dosing Unit (ODU), monitoring of BWTS equipment conditions, crew familiarization, monitoring by the Duty Officer, maintenance implementation, monitoring of ballast operations, seawater salinity, and water characteristics. The analysis shows that increasing crew familiarization with the BWTS and coordinating with the maker to conduct comprehensive System inspections and troubleshooting are efforts that can support BWTS operation. In addition, the replacement of Consumable parts in accordance with the maker’s recommendations and the implementation of periodic maintenance are necessary to maintain System reliability. By implementing these measures, BWTS operation is expected to become more effective, thereby ensuring that the ballast water treatment process continuously supports compliance with the requirements of BWMC Regulation D-2. 2025-01-01T00:00:00Z http://repository.stipjakarta.ac.id//handle/123456789/5758 PENGARUH 90 DAYS PLANNER DAN KELENGKAPAN DATABASE DOKUMEN TERHADAP KINERJA DEPARTMEN CREWING DI PT CIPTA WIRA TIRTA SIANIPAR, WILLIAM The performance of the Crewing Department at PT Cipta Wira Tirta determines vessel operational continuity and compliance with international maritime regulations. The company faces obstacles such as unstandardized short-term work planning mechanisms and incomplete crew document databases. This condition triggers administrative delays, rework, and deviation cases between planned and actual crew changes. This study aims to analyze the partial and simultaneous effects of 90 Days Planner implementation (X1) and crew document database completeness (X2) on the performance of the Crewing Department (Y) at PT Cipta Wira Tirta. The researcher used a quantitative approach with an explanatory research design. Primary data collection utilized a Likert scale questionnaire through a saturation sampling (census) technique on 32 respondents from a total population of 32 employees. Data analysis methods applied multiple linear regression assisted by SPSS version 26 software. The $t$-test results prove that the implementation of the 90 Days Planner has a partial positive and significant effect on department performance with a contribution of 77.6% tcount = 4.990 > ttable = 2.04227). The completeness of the crew document database also has a partial positive and significant effect with a contribution of 66.4% tcount= 2.653 > ttable = 2.04227). Simultaneously, both independent variables have a positive and significant effect with a combined contribution of 81.9% to the variation in department performance Fcount = 65.769 > Ftable = 3.33). These findings confirm that the integration of timeline planning controls and database quality accelerates the verification process and supports accurate seafarer placement. This study concludes that systematic placement schedule management and disciplined data updates optimize the long-term operational performance of the crewing division. Company management needs to standardize the 90 Days Planner digital dashboard, conduct weekly monitoring meetings, and implement an automatic early warning alert system for certificate expiration dates. Future researchers are advised to expand the scope of the study by increasing the research sample size. 2025-01-01T00:00:00Z http://repository.stipjakarta.ac.id//handle/123456789/5757 Perancangan Sistem Berbasis Internet of Things (IoT) Dalam Monitoring Kelembapan Ruang Muat Guna Mendukung Efisiensi Proses Pemuatan Kapal Curah Pada MV.EVRYDIKI Guseva Simatupang, Yosia Humidity monitoring in the cargo holds of bulk carriers is a critical aspect of maintaining cargo quality and supporting the efficiency of the loading process. The manual monitoring methods previously employed have significant limitations in terms of data continuity, accuracy, and operator dependency, often resulting in delayed detection of environmental changes within the cargo hold. This study aims to design and develop a prototype Smart Maritime Cargo Monitoring System based on the Internet of Things (IoT) using an ESP32 microcontroller and DHT22 sensor as an automated and real-time atmospheric monitoring solution for the cargo holds of bulk carrier MV. EVRYDIKI. This study employs a Research and Development (R&D) methodology based on a simplified Borg and Gall development model, consisting of four main stages: needs identification, planning, system design and prototype development, and testing and refinement. The developed system integrates a DHT22 sensor to measure temperature and relative humidity, an ESP32 microcontroller as the main control unit, a buzzer as an early warning alarm, and a web-based monitoring application accessible via smartphone or computer in real-time. Test results demonstrate that the system operates with an average error rate of 1.9%, well below the 5% industry tolerance threshold. The system also proved capable of detecting humidity anomalies and automatically activating the early warning system through two simultaneous alert channels: an acoustic buzzer installed in the cargo hold area and push notifications sent to the Officer on Watch's device. The system classifies cargo hold conditions into three categories: "NORMAL", "CAUTION", and "DANGER". Validation by expert lecturers in the fields of Nautical Science and Instrumentation, along with 20 Nautical Science cadets who had completed sea service, yielded an accumulated feasibility percentage of 96%, placing the prototype in the "Highly Appropriate" category. The Smart Maritime Cargo Monitoring System prototype is therefore declared fit for implementation as an effective and sustainable cargo hold environmental monitoring tool aboard bulk carrier vessels. 2025-01-01T00:00:00Z http://repository.stipjakarta.ac.id//handle/123456789/5756 "OPTIMALISASI PERAWATAN KOMPRESOR UDARA UNTUK KELANCARAN OPERASIONAL MESIN INDUK PADA MV MALAHAYATI BARUNA" DHAIFULLAH DJ, ALTHAF Air compressors are essential auxiliary machinery that play a crucial role in supporting the smooth operation of the main engine on board a vessel. Any disruption in the air compressor system can lead to reduced performance of the main engine starting system and may affect overall ship operations. Therefore, an optimal maintenance system is required to ensure that the air compressor operates effectively and continuously. This study aims to identify the problems occurring in the air compressor system and analyze efforts to optimize maintenance in order to improve the operational reliability of the main engine on MV. Malahayati Baruna. The research method used is descriptive qualitative, with a field study approach through direct observation, interviews, and documentation during sea practice. The results show that the main problems in the air compressor system are caused by suboptimal implementation of periodic maintenance, corrosion in several components, and lack of monitoring of the cooling and air filter systems. The proposed solutions include improving the Planned Maintenance System (PMS), conducting routine inspections, replacing worn-out components, and enhancing maintenance discipline according to the manufacturer’s manual. In conclusion, the optimization of air compressor maintenance significantly improves the reliability of the compressed air system and supports the smooth operation of the main engine on board. With a well-planned and scheduled maintenance system, the risk of operational failure can be minimized. 2025-01-01T00:00:00Z
