ANALISIS PENGGUNAAN ANCHOR WINDLASS GUNA MENDUKUNG OPERASIONAL KAPAL SAAT BERLABUH JANGKAR DI MV. GLOVIS DAYLIGHT AIEN SUDARMAN, RO'YAL Ship operations during anchoring are highly dependent on the performance of deck machinery systems, particularly the anchor windlass. This system plays a crucial role in withstanding the tension of the anchor chain and ensuring the vessel can anchor safely, while maintaining the ship's position against excessive movement caused by extreme weather conditions. This study aims to identify and analyze the root causes of operational failures, specifically the damage to the windlass motor ball bearings due to chain tension exceeding design capacity limits, as well as severe wear on the chain stopper bearing surface triggered by repetitive impacts and shock loads. This study employs a descriptive qualitative method using the Fishbone Analysis approach, based on the author's sea project experience (Praktik Laut) aboard MV GLOVIS DAYLIGHT. During the internship, cases of anchor dragging and a breakdown of the port-side windlass motor were identified, caused by heavy swells and strong winds in the waters of Port Kembla, Australia. The results of this research are expected to provide effective handling and problem-solving practices through the implementation of a VFD-based Load Monitoring System to dampen shock loads and the use of the Hard-facing Coating method to increase the durability of the chain stopper material. These mitigation steps are expected to prevent premature mechanical damage, maintain the smoothness of anchoring operations, and ensure ship safety. Keywords: Ball bearing damage, Chain stopper wear, Anchor windlass, Load Monitoring System, Hard-facing coating.

OPTIMALISASI PROSEDUR CARGO HOLD CLEANING BERBASIS PENDEKATAN INTERNET OF THINGS (IOT) DALAM UPAYA MENINGKATKAN KESELAMATAN KERJA DI MV FEDERAL OAK ARDY WINANTORO, MUHAMMAD This study aims to analyze the causes of work accidents and the suboptimal implementation of cargo hold cleaning procedures on board MV. Federal Oak, as well as to formulate optimization efforts to improve crew work safety. The research uses a qualitative approach with a descriptive analytical method. Data were collected through direct observation during sea practice, interviews with crew members, and documentation studies related to work procedures and ship safety reports. Data analysis was conducted through data reduction, data presentation, and conclusion drawing supported by root cause analysis using the 5 Why method. The results of the study indicate that work accidents during cargo hold cleaning activities were caused by the suboptimal implementation of safety procedures, such as the handover of equipment while still in operation, improper modification of equipment, and weak supervision from responsible officers. In addition, the inconsistent implementation of safety meetings, inadequate use of personal protective equipment (PPE), and limited crew understanding of safety management also contributed to the occurrence of work accidents. The Internet of Things (IoT) approach in this study is used as a conceptual framework to support a more systematic work safety monitoring system through monitoring work activities, crew working hours, and compliance with safety procedures. By optimizing the implementation of cargo hold cleaning procedures, strengthening supervision, and enhancing the safety culture among crew members, it is expected that cargo hold cleaning activities can be carried out more safely and in accordance with the applicable occupational safety standards on board MV.

PERANCANGAN SISTEM IOT GUNA MONITORINGTEMPERATUR DAN KELEMBAPAN MUATAN BATU BARA PADA MV. BULK BATAVIA AULIA, HAFIZ Coal as a bulk cargo has the potential to undergo spontaneous heating (self-heating) due to oxidation processes influenced by temperature and humidity inside the cargo hold. On board MV. Bulk Batavia, cargo condition monitoring is still conducted manually and periodically, resulting in temperature and humidity fluctuations that are not observed in real time. Previous studies have generally focused on IoT-based monitoring systems in warehouses or land-based storage facilities, while the implementation of real-time and continuous monitoring systems for coal cargo on ships remains limited. Based on this condition, this study aims to design an Internet of Things (IoT)-based monitoring system to measure coal cargo temperature and humidity in real time and continuously in order to detect early symptoms of self-heating and maintain cargo quality during the voyage. This research employed a Research and Development (R&D) approach using a prototype model through stages of needs analysis, design, development, implementation, and evaluation. The system was developed using an ESP32 microcontroller, a PT100 temperature sensor integrated with the MAX31865 module, an SHT31 humidity sensor, an I2C LCD, a buzzer as an alarm indicator, a 5V cooling fan, and the Blynk application for remote monitoring. Testing results showed average temperature and humidity changes of 7.44 °C and −4.4%, respectively, in charcoal briquette simulations, and 6.24 °C and −3.2% in heat gun simulations. The threshold test confirmed that the system automatically activated the alarm when the temperature exceeded 55 °C with a 100% success rate and no false alarms or error. A four-hour stability and endurance system test demonstrated low standard deviation values of 0.33 °C for temperature and 0.89% for humidity, indicating minimal fluctuations and stable sensor readings without significant deviation, as well as stable Blynk connectivity without data loss. Validation results indicated a feasibility score of 98.67% from nautical and IoT experts and 95.8% from 20 nautical cadets, both categorized as “Highly Appropriate.” This research demonstrates that the designed IoT-based monitoring system satisfies functional, technical, and operational criteria as an early warning system for detecting initial signs of self-heating and preventing the degradation of coal cargo quality through real-time and continuous monitoring of temperature and humidity in the cargo hold. Future work is recommended to include the integration of gas sensors, the implementation of backup power systems, and the addition of visual indicators at critical temperature thresholds to enhance monitoring effectiveness in ship operational environments. Keywords: Coal; Humidity; Internet of Things; Self-heating; and Temperature.

PENGEMBANGAN DRONE UNTUK PENGUKURAN ATMOSFER & VISUAL INSPECTION DI ENCLOSED SPACE TANPA HUMAN ENTRY DWIPA DAMAR JATI, ARYA This research aims to analyze the potential utilization of unmanned aerial vehicles (UAVs) or drones in conducting atmospheric measurement and visual inspection in enclosed spaces on board ships without human entry, as well as to identify the technical and operational challenges in their implementation. This study employs a descriptive qualitative method with a case study approach based on observation, interviews, and literature review conducted during sea practice on board MT. Hafnia Bobcat. The results show that enclosed space entry activities still pose a high risk of accidents due to the presence of hazardous atmospheric conditions such as oxygen deficiency, toxic gases, and flammable gases. In addition, conventional inspection methods still require crew members to enter confined spaces, which increases exposure to hazards and the possibility of human error. Analysis using a Fishbone Diagram indicates that the limited implementation of drone technology is influenced by several factors, including the lack of crew competence in operating drones, the absence of standardized operational procedures for UAV use in enclosed spaces, technical limitations of drones such as flight stability and battery endurance, and environmental conditions inside enclosed spaces such as poor lighting and complex structural layouts. Therefore, improvements are needed in drone operator training, the development of standardized operational procedures integrated into the Safety Management System (SMS), technological enhancement of drones to better adapt to enclosed environments, and gradual evaluation of this technology to improve occupational safety and reduce the risk of accidents during enclosed space entry activities on board ships.
