Abstract

The development of a data acquisition and control system based on modern technologies plays a crucial role in supporting aquatic environmental exploration using Unmanned Surface Vehicles (USVs). This project aims to design and implement a command-and-control unit capable of integrating water survey instruments with microcontroller-based sensors, targeting the real-time display of depth data, GPS location, and graphical visualization on an Smartphone application. The system employs the ESP32 module as the bridge between USV sensors—such as a single-beam echo sounder for depth measurement and a GPS module—and the user application. Wi-Fi connectivity is utilized for fast and efficient data transmission between the USV and the mobile interface. In this project, the Arduino IoT Cloud platform is adopted to simplify the integration of real-time data into the user interface, eliminating the need to develop an application from scratch. The system is designed to be cost-effective, portable, and user-friendly. This project is expected to demonstrate the system’s capability to process sensor-acquired data, control the USV’s movement direction, and display the results in numerical and graphical formats on the user's Android device in real time

Abstract

This study investigates household willingness to adopt sustainable waste management practices in Gorontalo Province, Indonesia, a coastal region where unmanaged solid waste directly threatens marine natural capital such as mangroves, seagrass, and coral reef habitats. Using an extended Theory of Planned Behavior (TPB) framework, the research incorporated adaptive capacity as a governance-related antecedent to explain household pro-environmental behaviors. A cross-sectional survey of 63 respondents was conducted, and the data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results demonstrate that attitudes had a modest effect on behavioral intentions (H4, p = 0.038), while subjective norms strongly predicted both perceived behavioral control (H2, p < 0.001) and intentions (H5, p < 0.001). Perceived behavioral control emerged as a decisive factor shaping intentions (H6, p = 0.002) and indirectly influencing behaviors (p = 0.012). Adaptive capacity significantly strengthened perceived behavioral control (H3, p = 0.028), confirming the importance of governance support in enabling household action. Finally, intentions strongly predicted actual behaviors (H7, p < 0.001), such as reducing single-use plastics and avoiding littering in coastal areas. These findings suggest that enhancing governance capacity, reinforcing social norms, and building household confidence are critical for aligning community waste practices with marine ecosystem protection.

Abstract

Gas compressors are vital equipment in the oil and gas industry that function to maintain the smooth production and transportation of natural gas. Compressor failure can cause significant downtime, financial losses, and safety risks. This study aims to evaluate the maintenance policy of the KN-02 gas compressor at the Nibung Gas Compressor Station (SKG) using the Reliability Centered Maintenance II (RCM II) method. Engine fault data was collected in the period September–October 2024 and analyzed through Failure Mode and Effect Analysis (FMEA), Logic Tree Analysis (LTA), and Fishbone Diagram to identify critical failure modes and root causes. Furthermore, the proposed treatment strategy was formulated using the RCM II Decision Worksheet. The results of the analysis showed three critical components with the highest Risk Priority Number (RPN) values, namely cylinder oil supply failure (RPN = 671), valve suction/discharge (RPN = 662), and packing rod (RPN = 577). Based on the results of the LTA, the recommended types of maintenance include scheduled restoration, scheduled discard, and condition-directed maintenance. Fishbone's analysis indicates that the root cause comes from material wear factors, lubrication quality, and maintenance procedure errors. With the implementation of an RCM II-based maintenance strategy, compressor engine downtime is expected to be reduced by more than 40%, while improving the operational reliability of the system. This study confirms that RCM II is effective as a systematic approach in determining optimal oil and gas machinery maintenance policies.

Abstract

This study analyzes the longitudinal strength of a container ship under hogging and sagging conditions using the Nonlinear Finite Element Analysis (NLFEA) method. Numerical modeling was performed on a single frame spacing of the container ship to evaluate the stress and deformation distribution due to longitudinal bending loads. A three dimensional finite element model was developed using SHELL181 elements in ANSYS software, employing large displacement static analysis. The results show that under hogging conditions, the deck experiences a maximum tensile stress of 410.28 N/mm², while the bottom structure undergoes a compressive stress of -405.93 N/mm². Under sagging conditions, the deck experiences a compressive stress of 279.91 N/mm², and the bottom experiences a tensile stress of -387.80 N/mm². The ultimate bending moments were 1.42 × 10¹³ Nmm for hogging and -1.21 × 10¹³ Nmm for sagging, indicating that the ship is more susceptible to structural failure under sagging conditions. These findings highlight the importance of considering both loading conditions in the structural design of container ships to ensure safety and operational efficiency.

Abstract

This study experimentally characterizes Municipal Solid Waste (MSW) feedstock to assess its suitability for gasification-based Waste-to-Energy (WtE) systems. Ten samples from different urban collection sites underwent thorough analysis using standardized ultimate and proximate methods, alongside bomb calorimetry on a dry basis, which helped to ensure the results accuracy. A strong positive correlation was observed between carbon and hydrogen content and gross calorific value, while oxygen, nitrogen, sulphur, and ash content exhibited a negative correlation with calorific potential. Notably, plastics and complex waste yielded the highest gross calorific values, around 30,000 kJ/kg and 31,600 kJ/kg, respectively, while high-ash content fractions recorded the lowest values at about 6,600 kJ/kg. The presence of volatile matter and fixed carbon positively impacts energy release, whereas ash dilutes fuel quality and increases heat absorption during combustion. The study suggests that pretreatment strategies, such as moisture reduction, ash fraction removal, and selective sorting for hydrocarbon-rich materials, effectively enhance fuel quality for gasification and reduce nitrogen and sulphur emission risks. The data reveal significant variability among different waste fractions, indicating that effective feedstock management and reactor design must address compositional heterogeneity to ensure reliable gasification performance.

Abstract

Tourists turn to rural tourism because of its distinctiveness in relation to nature, the hospitality of the locals, and its unique food. However, Central Tapanuli Regency's tourism growth remains uneven due to a lack of infrastructure, knowledge, and policies that prioritize urban regions. The Central Tapanuli Regency Government has to create a tourist strategy that takes coastal rural development into account. In Central Tapanuli Regency, the Smart Rural Tourism Model (PARIPEDAS) encourages the growth of tourism by utilizing village potential, community engagement, natural preservation, and local knowledge. The study employs a mixed methodological approach to ascertain policymakers' perspectives, assess the function of rural communities, and develop a PARIPEDAS model using Structural Equation Modeling (SEM) analysis based on Central Tapanuli Regency's coastline potential. While the PARIPEDAS model requires more research to be in line with regional development plans, the research determined that the ideal approach was to empower and include coastal communities in the implementation of tourism and development, concentrating on the distinctive value of tourist attractions and protection of natural assets.

Abstract

Material procurement in the supply chain accounts for 60% of the ship contract value and has the highest burden with the largest portion of fund distribution, often resulting in procurement delays. This has an impact on delays in the delivery of modular ship construction. Supply chain performance delays are partly due to conventional auction methods, which result in many cases of fraud and a greater potential for material delays. The potential for losses results in delays in ship production, even though risk assessment activities have been carried out as an improvement for the shipyard. The purpose of web-based electronic auction research is to find efficient and accountable prices that can be justified. On the other hand, manual meetings are not necessary, as vendors can participate in meetings and the auction process from their respective locations, minimizing the potential risk of delays in the supply chain material procurement and enabling the production process to proceed according to the initial contract. The results of the research are in the form of an E-Auction user interface for auction processes with two functions, namely administrator login and login for partners or vendors implementing E-Auction auctions, thereby improving aspects of technology, management, marketing, and human resources.

Abstract

This study aims to evaluate the performance improvement of fishing vessels made of fiberglass-reinforced plastic (FRP) using locally manufactured propulsion components. Two vessels, KM. Nelayan 271 and KM. Nelayan 371, were tested to identify and resolve the underperformance issue, as both initially failed to achieve the target service speed of 7 knots. The experimental approach involved field installation, configuration adjustment, and sea trials. On KM. Nelayan 271 , the original D22×P20 (three-blade) propeller was replaced with a D24×P22 (four-blade) model, resulting in a speed increase from 5.3 to approximately 7.1 knots at 2000 RPM. On KM. Nelayan 371, the gearbox was replaced from WHG17G (3:1) to MA125 (2:1), allowing the vessel to exceed 8.3 knots using the same propeller configuration. These results demonstrate that optimizing the gearbox ratio and propeller geometry effectively restores the propulsion balance and enhances vessel performance. The findings provide empirical validation that domestically manufactured components, specifically the B-Series propellers produced by BTH Surabaya, can meet the operational standards for small fishing vessels. This achievement supports Indonesia’s initiative to strengthen the TKDN policy and reduce reliance on imported marine propulsion systems.

Abstract

The management of ship energy significantly affects both cost efficiency such as earnings before interest and environmental sustainability, particularly in reducing CO₂ emissions produced by ship operations. Despite the importance of this issue, research on ship energy consumption within container terminals remains limited. This study aims to estimate CO₂ emissions generated by ship activities in container ports, focusing on emission variables related to the Ship Energy Efficiency Management Plan (SEEMP). The calculation considers active ship movements in the port, including approach, maneuvering, and berthing processes. Energy consumption and CO₂ emissions were analyzed using random forest regression (RF) with default settings, and the model’s accuracy was validated through k-fold cross-validation. The results identified five major factors influencing CO₂ emissions: (1) main engine power, (2) auxiliary engine power, (3) waiting time in the port, (4) maneuvering time, and (5) berthing time. Among these, maneuvering, waiting, and berthing showed the highest significance, confirmed by attribute selection and validation results. The random forest model demonstrated a prediction accuracy of 98.89%, confirming its reliability. Moreover, operational fuel efficiency analysis indicated that combining voyage optimization, skilled operators, and cold ironing facilities could reduce CO₂ emissions by up to 20%. These findings provide valuable insights and serve as a foundation for developing a more effective Ship Energy Efficiency Management Plan to enhance environmental performance in maritime operations.

Abstract

Traditional fishing vessels in Tambak Lorok are commonly constructed based on inherited craftsmanship and empirical experience, without adherence to any formal classification standard. Consequently, variations in the mechanical strength of wooden materials due to dimensional differences require further investigation. This study aims to examine the differences in destructive stress values that occur after the vessel experiences an impact, with reference to the Bureau of Classification Indonesia (BKI) criteria. The methodology involves recalculating the structural dimensions of wooden ship components following BKI standards and conducting localised impact tests at a standard berthing velocity of 0.25 m/s, with vessel speeds ranging from 1 knot to 2.5 knots. The analytical and experimental findings reveal a construction weight reduction of 258 kg, equivalent to approximately 42% lighter than the conventional design. The safe stress limits were determined to be 102.88 MPa on the frame and around 30 MPa on the hull plating under a 2-knot collision. These results demonstrate that applying BKI criteria enhances both structural efficiency and economic value while maintaining safety under standard berthing conditions.
