Abstract

The development of Internet of Things (IoT) technology has made a significant contribution to the advancement of monitoring systems in the maritime sector, particularly in supporting the safety and operational efficiency of vessels. One of the common problems encountered in traditional fishing boats is overheating in the pod propulsion unit due to the limited availability of real-time temperature monitoring systems. This study aims to design and implement an IoT-based temperature monitoring system for the pod propulsion unit of traditional fishing boats using an ESP32 microcontroller. The developed system utilizes DHT11 and BMP180 sensors to detect temperature, humidity, and pressure parameters in the engine environment, and transmits the data in real time to the ThingSpeak cloud platform via an internet network. This research employed an experimental engineering approach consisting of hardware design, software integration, system testing, and monitoring performance analysis. Testing was conducted on an engine simulator and a traditional fishing boat with data acquisition intervals of 10–20 minutes. The results show that the system is capable of monitoring temperature in real time, displaying data locally through an OLED LCD, and providing remote visualization through a cloud-based platform. The system can also present continuous temperature data and facilitate engine condition monitoring to support overheating prevention. However, system performance is still influenced by internet connection stability and the limited accuracy of the DHT11 sensor at high temperatures. This study contributes to the development of an energy-efficient, easy-to-implement IoT-based maritime monitoring system suitable for traditional fishing boats in Indonesia.

Abstract

The electric motor of a ship’s sewage pump operates continuously and plays an important role in the ship’s sanitation system. Therefore, motor condition monitoring is required to prevent operational disruptions. Motor damage is generally preceded by increased vibration caused by imbalance, bearing wear, or improper installation. This study aims to design a real-time monitoring system for electric motor damage of a ship’s sewage pump using a piezoelectric sensor as a vibration detector. The research method used was an experimental method consisting of system design, static testing, dynamic testing, and data analysis. The system was designed using a Moswell MW 125 motor as a representation of the sewage pump motor, a piezoelectric sensor as the vibration detector, an ESP32 microcontroller as the data processor and transmitter, and Node-RED as the monitoring display platform. Dynamic testing was carried out for 30 minutes with data readings taken every 5 minutes. The test results showed that the monitoring system worked according to the design. The motor vibration value under normal conditions ranged from 0.2 to 0.5 mm/s during the testing period, which was categorized as safe and stable. The system was able to display vibration data in a real-time, continuous, and accurate manner through the dashboard. Therefore, the piezoelectric sensor-based monitoring system can be used as an early detection tool for motor damage and to support preventive maintenance of the ship’s sewage pump electric motor.

Abstract

This study aims to design and develop an Internet of Things (IoT)-based electrical energy source monitoring system for ships to support the utilization of renewable energy, particularly Wind Power Generation (WPG). The background of this research is the continued use of manual monitoring systems, which are less effective, prone to recording errors, and unable to provide real-time data monitoring. The developed system utilizes a ZMPT101B voltage sensor, an ACS712 current sensor, an ESP32 microcontroller, a 20×4 I2C LCD, and the Node-RED platform for data visualization and storage. This study employs a quantitative experimental method, including hardware design, software development, and static and dynamic testing. Testing was conducted at two locations, namely the Merchant Marine Polytechnic of Surabaya and Kenjeran Beach, Surabaya, for 8 hours. The results show that the system performed successfully, displaying real-time data through both the LCD and Node-RED dashboard while also enabling automatic data logging without data loss. The ACS712 sensor exhibited an error range of 2.38%–7.14%, while the ZMPT101B sensor showed an average error of approximately 0.8%. Based on these results, the developed IoT-based monitoring system is considered feasible for shipboard electrical monitoring and has the potential to improve operational efficiency in electrical monitoring activities.

Abstract

The development of cluster housing requires integrated management involving civil engineering aspects, construction quality control, project management, cost efficiency, time scheduling, and post-construction maintenance. This colloquium study discusses engineering practices in the Britania Cilegon Housing Project developed by PT. MAS Group, focusing on the construction of Phase I consisting of 160 housing units of type 40 and type 51 out of the total planned area of 535 plots. The methods applied in this study included field observations, project document analysis, technical coordination with the developer and contractors, and engineering evaluation of construction implementation and building maintenance processes. The results indicate that land procurement and site preparation were generally carried out effectively; however, the land elevation, which was relatively close to the river level, required stricter supervision of fill work and drainage systems. Housing designs were prepared internally by the developer, while construction activities were divided based on block zones, house types, and Work Order Letters (SPK). Several major issues identified during construction included inconsistencies in work quality among contractors, violations of construction procedures, project delays caused by inefficient allocation of contractor resources, and defects found in roof structures, wall finishes, and wet areas. Control measures were implemented through quality checklists, progress monitoring using bar charts and S-curves, corrective instructions, and penalties in the form of budget deductions when repairs were conducted directly by the developer. This engineering practice demonstrates that successful housing development is strongly influenced by consistent supervision, sustainable design innovation, environmental awareness, and commitment to maintaining residential quality.

Abstract

Man overboard (MOB) incidents remain one of the most critical emergencies in maritime operations due to the high risk of loss of life and the limited time available for rescue actions. The effectiveness of MOB handling is highly dependent on crew response, communication, coordination, and adherence to established safety procedures. This study aims to analyze the conformity of man overboard handling implementation on KM. Tidar with the Safety Management System (SMS) of PT PELNI. A descriptive qualitative approach was employed using observation, semi-structured interviews, documentation, and NVivo-assisted data analysis during sea practice onboard KM. Tidar. Data were analyzed through data reduction, data display, and conclusion drawing techniques. The findings indicate that MOB handling on KM. Tidar consists of six stages: initial detection, initial response actions, emergency communication, rescue maneuver, search operation, and follow-up actions. Most procedures were implemented in accordance with the company’s SMS, particularly in emergency communication, rescue maneuver execution, and search operations. The Williamson Turn maneuver was applied effectively under limited visibility conditions during nighttime operations. However, procedural non-conformities were identified at the initial detection stage, including the absence of verbal “man overboard” warning, failure to activate the emergency alarm, and incomplete initial recording procedures. These issues were influenced by human factors, operational pressure, and emergency conditions. The study concludes that MOB handling was operationally effective but not fully compliant with SMS requirements, emphasizing the need to strengthen emergency preparedness and safety culture onboard vessels.

Abstract

This study aims to analyze the effects of condenser pipe configuration, refrigerant charge, and condenser airflow velocity on the performance of a refrigerator using R-600a refrigerant. The condenser pipe configurations investigated were U10, U12, and U14, with refrigerant charges of 46 g, 48 g, and 50 g, and condenser fan speeds of 1000 rpm, 1200 rpm, and 1300 rpm. The observed parameters included the refrigerant mass flow rate (ṁ), compressor work (W), condenser heat rejection capacity (Qc), and Coefficient of Performance (COP). The analysis was conducted based on enthalpy data at each point of the refrigeration cycle and the performance test results of the cooling system.The results indicate that increasing the number of condenser pipe passes and the refrigerant charge tends to enhance the condenser's heat rejection capability, thereby improving overall system performance. The optimum configuration was achieved with the U14 condenser pipe arrangement, a refrigerant charge of 50 g, and a condenser airflow velocity corresponding to a fan speed of 1300 rpm. This configuration produced a refrigerant mass flow rate of 0,0184 kg/s, compressor work of 1,32 kW, condenser heat rejection capacity of 5,65 kW, and the highest COP value of 4,28. In contrast, the lowest performance was obtained with the U10 condenser pipe arrangement, a refrigerant charge of 48 g, and a fan speed of 1000 rpm, resulting in a COP of 3,27. In general, increasing the condenser airflow velocity improved the condensation process and enhanced system efficiency, particularly for longer condenser pipe configurations. The findings demonstrate that the combination of condenser pipe configuration, refrigerant charge, and condenser airflow velocity has a significant effect on the performance and energy efficiency of an R-600a refrigerator.

Abstract

Climate change issues and dependence on fossil fuels have driven a rapid increase in electric vehicle development, including electric shuttle buses for public transportation. Although superior in emissions and noise levels, these vehicles still face challenges in energy efficiency, particularly due to aerodynamic drag at medium to high speeds. This study aims to analyze the wake zone characteristics and Turbulent Kinetic Energy (TKE) distribution on a 14-seat electric shuttle bus to comprehensively understand the mechanisms of aerodynamic drag. The method employed is a Computational Fluid Dynamics (CFD) numerical simulation using the SST turbulence model. Simulations were conducted at velocity variations of 20 km/h, 40 km/h, and 60 km/h. The simulation results indicate that increasing velocity strengthens the flow separation phenomenon, triggering an expansion of the wake zone length from 19.51 cm to 30.05 cm. This expansion correlates linearly with a sharp surge in the maximum TKE value from 530 m2/s2 to 6,100 m2/s2, which significantly contributes to the increase in total drag force. These findings imply that aerodynamic evaluation should not solely rely on the global drag coefficient but must also account for the management of wake structures and turbulent energy. Ultimately, this research provides a strategic foundation for vehicle body design optimization to enhance the energy efficiency and driving range of electric shuttle buses.

Abstract

As the manufacturing industry continues to evolve, competition has become increasingly intense. Consequently, companies are required to enhance operational performance, data integration, and decision-making effectiveness. To address these challenges, many organizations have adopted Enterprise Resource Planning (ERP) systems as the primary platform for operational integration. However, systematic analyses of the impact of ERP implementation on production performance and operational performance remain limited. This study aims to examine how ERP implementation supports manufacturing production systems. The aspects analyzed include production planning, inventory control, process efficiency, and overall operational performance. The research employed a Systematic Literature Review (SLR) approach using data sources published between 2016 and 2024 and indexed in Scopus, Web of Science, and Google Scholar. Of the 312 articles initially identified, 73 met the inclusion criteria and were subsequently analyzed through bibliometric and categorical evaluations. The findings indicate that ERP implementation improves production efficiency by an average of 22.4%, increases inventory accuracy by 21.5%, and reduces lead time by up to 50%. In addition, operational costs decrease by an average of 17.8%, while customer satisfaction increases by 19 points. Production management, procurement, and warehouse management were identified as the three key components influencing these improvements. This study provides comprehensive insights for practitioners and researchers in designing effective ERP implementation strategies within the manufacturing sector.

Abstract

This study aims to analyze the implementation of the Dynamic Positioning (DP) system on the Platform Supply Vessel (PSV) S Panglima in dealing with adverse weather conditions during offshore operations. A descriptive qualistative method was employed, with data collected through direct observation, interviews with the Dynamic Positioning Operator (DPO), and documentation from the vessel's Dynamic Positioning System (DPS). The results indicate that the Dynamic Positioning Class 2 system was able to maintain the vessel's position effectively under wind speeds of up to 30 knots and wave heights of up to 3 meters, with an average position deviation of less than 3 meters and thruster utilization ranging from 75% to 95%. However, under extreme weather conditions, system performance declined due to sensor disturbances and increased propulsion loads. Manual intervention by the DPO using Hybrid Control mode proved effective in stabilizing the vessel's position and preventing loss of position. Adverse weather conditions increased fuel consumption by up to 70% and reduced operational efficiency by approximately 12%; nevertheless, the DP system remained an effective solution for maintaining the vessel's position without anchoring, thereby enhancing operational safety and efficiency at sea. The study concludes that the successful implementation of the DP system under severe weather conditions depends on sensor reliability, proper system maintenance, and operator competence. Therefore, routine sensor calibration, extreme weather simulation training for DPOs, and the integration of real-time weather monitoring systems are recommended to further improve Dynamic Positioning performance in offshore vessel operations.
