Abstract

This paper presents a comprehensive structural integrity assessment of a 50,000-kiloliter aboveground steel storage tank that experienced shell denting during hydrostatic testing. Dents and geometric imperfections are known to significantly affect the buckling behavior and load-bearing capacity of storage tanks. To evaluate the tank’s fitness for service (FFS), a Level 3 assessment was conducted following API 579-1/ASME FFS-1 Part 8 standards. Finite element analysis was employed to simulate the elastic stress distribution and fatigue behavior under various loading conditions, including hydrostatic pressure, wind, and seismic loads. Results revealed that shell course 7 and 8 experienced stress increases of up to 2282% compared to the undistorted condition, with von Mises stress remaining below the allowable limits. A fatigue analysis confirmed that stress amplitudes were below the fatigue threshold, resulting in infinite fatigue life. Furthermore, discharge simulation indicated that improper dewatering could induce external pressure exceeding the material’s yield strength, leading to localized plastic deformation. Nevertheless, the dented tank was found to be structurally sound and compliant with API 650 and API 579-1/ASME FFS-1 criteria. The study highlights the importance of proper discharge procedures and confirms that no immediate repair is required for continued safe operation of the tank.

Abstract

Aging offshore platforms require a reliable drainage system to ensure safety and operational efficiency. This study aims to analyze the adequacy of the closed drain and open drain systems on a 24-year-old offshore platform that is scheduled for redevelopment. The methodology employed involves hydraulic analysis, considering fluid production rates and drainage system design data based on API 14E and GPSA (2004) standards. The collected data included channel cross-section dimensions, flow rates, and fluid characteristics to calculate the system's capacity. The analysis showed that the 4-inch header pipe was adequate to accommodate a closed drain flow rate of 167.4 BPD and an open drain flow rate of 1.63 BPD. The Slop Tank (Platform X-T-26), with a geometric volume of 54 ft3, was also adequate to contain the maximum drainage volume of 15.23 ft3 from the Vertical Test Separator. This study also identified several critical points that require periodic monitoring to prevent blockages and performance degradation. This study emphasizes the importance of periodic inspections to assess the adequacy of drainage systems on aging offshore platforms to ensure safety and operational efficiency after redevelopment. It also provides preventive maintenance recommendations to extend the system's lifespan.

Abstract

Sepanjang Beach offers a broad, long stretch of sand with a small quantity of coral and limestone hills that have turned into cliffs. Through its natural scenery, visitors become interested in visiting Sepanjang Beach. The purpose of the study was to analyze the level of suitability of tourism for sustainability. Meanwhile, research related to the area's carrying capacity was carried out to determine the ability of natural resources to maintain their function and quality to provide the recreational experience visitors want. For the sake of ecosystem availability, it is necessary to apply ecotourism principles to provide behavioral limits for humans as tourism actors to carry out recreational activities without reducing tourist satisfaction. The tourism suitability data collection technique uses 11 parameters: beach type; beach width; water depth; water bottom materials; beach slope; current speed; the brightness of the waters; closure of coastal land; dangerous biota; and availability of fresh water. While the carrying capacity of the area is calculated by calculating the economic level of the community around the tourist area, community contribution, visitor activities, the size of the area that visitors can use, length of visit, and the length of time the tourist area is open in one day. The results of the tourist suitability analysis at station 1 were 2.32, station 2 was 2.32, and station 3 was 2.2. The results show the area's carrying capacity is 240 people/day for fishing activities and 744 people/day for visitor recreation activities.

Abstract

The performance of a diesel engine is greatly influenced by fuel. Diesel engines really need clean fuel so that engine combustion is maximized. Many companies today prefer fuel oil because it is cheaper than other fuels but fuel oil is still contained by water, mud and dirt so it requires a purifier aircraft to separate the fuel from these impurities. The purpose of this study is to find out how the results of diesel engine combustion are if maintenance is carried out on the purifier periodically. This research method uses descriptive qualitative. The data source was obtained directly by means of observation and documentation as well as literature related to this research which was carried out during the sea project for 12 months at KM.

Abstract

The waters of Raja Ampat in Papua are one of the world's top maritime tourism destinations, attracting over 30,000 tourists annually since 2020. However, the challenging geographical conditions, such as shallow coral reefs, strong sea currents, and busy speedboat traffic, significantly increase the risk of maritime accidents. According to the National Disaster Management Agency (BNPB), from 2012 to 2024, six incidents in the area caused serious accidents, including vessel damage and injuries. This study aims to analyze the risks of tourist speedboat accidents in Raja Ampat using three complementary risk assessment methods: the Swiss Cheese Model (SCM), interviews, and questionnaires. The Swiss Cheese Model identifies gaps in several layers, such as Environment and Weather, Vessel and Safety Equipment, Skills and Competence of Operators, and Tourism Safety Management and Regulations. The analysis shows that the skills and competence of boat operators are significant weaknesses in accident cases, and it recommends that boat operators in Raja Ampat participate in SCRB (Survival Craft and Rescue Boat) training and certification programs.

Abstract

Aquaculture plays a vital role in global food supply, contributing nearly 43% of the food consumed by humans. The rapid growth in aquaculture production demands a significant amount of electricity, which accounts for approximately 40% of the total energy costs. The primary energy sources in aquaculture used fossil fuels, it can be reduced by utilizing alternative energy sources. This research aims to develop a prototype of a floating net cage using an Internet of Things (IoT)-based water quality monitoring system powered by solar energy. The water quality parameters monitored in this study include temperature, pH, salinity, and dissolved oxygen levels. The sensors used for monitoring these parameters have undergone testing. The results indicate that the sensors can perform accurate measurements with over 90% accuracy. The solar panels installed in the system are capable of generating sufficient power to meet the operational demands, allowing the system to operate for approximately two days without sunlight. By maintaining well-controlled aquatic environmental conditions through IoT-based monitoring and control systems supported by renewable photovoltaic solar energy, environmentally friendly aquaculture operations can be conducted efficiently and productively. Ultimately, this leads to the production of high-quality aquaculture products, cost-effective operations, and the utilisation of eco-friendly energy sources.

Abstract

Coastal urban areas in Indonesia, particularly in Jakarta, face complex sanitation challenges due to rapid urbanization, environmental vulnerability, and the persistence of informal settlements. While national programs like the 100-0-100 initiative and the KOTAKU (Kota Tanpa Kumuh) program aim to achieve universal sanitation access and slum eradication, implementation in flood-prone coastal zones remains constrained by rigid infrastructure models, fragmented governance, and limited community engagement. This study employs a narrative review approach to examine how principles of adaptive management can enhance the effectiveness, inclusiveness, and resilience of coastal sanitation systems. Drawing on literature from urban planning, environmental governance, and participatory development, the study synthesizes insights across five core dimensions of adaptive management: assets, flexibility, organization, learning, and agency. The resulting framework highlights the importance of leveraging local knowledge, enabling flexible planning and financing, promoting inter-agency collaboration, institutionalizing learning mechanisms, and strengthening community leadership. By aligning technical solutions with social realities and environmental dynamics, adaptive management offers a pathway to improve sanitation governance while supporting Indonesia’s broader sustainable development and climate adaptation goals. The study concludes with policy recommendations to integrate adaptive approaches into the design and evaluation of urban sanitation programs, ensuring that no community is left behind in the pursuit of inclusive and resilient urban futures.

Abstract

The previous Savonius wind turbine studies have proved that overlap modifications to conventional blades can improve turbine performance. With these conventional blades, the performance is less optimum because the drag force generated by turbine's rotation is still high. Based on this condition, this experiment is conducted by modifying Savonius wind turbine with overlap blades using Myring equation n = 1. Its blade profile is made half-elliptical to reduce drag force. Diameter and height of the turbine are 400 mm with 0.3 overlap ratio. The ratio of cylinder diameter (ds/D) is 0.4, and the ratio of cylinder center distance (S/d) is 1.7. Experiments are conducted by varying stagger angles of circular cylinder in front of returning blade are 45°, 50°, 55°, and 60° with velocity 5 m/s. The final results show that the best performance improvement of the turbine occurs at 60° stagger angle. The increase in torque coefficient is 4.95% and power coefficient is 20.16% to overlap Savonius wind turbine with myring n = 1 with no circular cylinder.

Abstract

This study comprehensively assesses safe loading conditions for the Self-Propelled Crane Barge (SPCB) Deck Crane by integrating detailed hydrostatic calculations with righting-arm (GZ) curve analysis. At the designated summer draft of 2.75 m, baseline parameters—displacement (1 716 t), centre of buoyancy (KB = 0.765 m), transverse metacentre (KM = 2.780 m), and metacentric height (GM = 1.23 m)—were established from the vessel’s stability booklet. Four loading scenarios (lightship, full ballast, crane at maximum outreach, and cargo distribution) were defined, with updated displacement and vertical centre of gravity (KG) values used to recompute hydrostatic parameters (BM, KM, free-surface corrections) and generate full GZ curves. Intact-stability criteria (GM >= 0.15 m, area under GZ curve >= 0.08 m·rad, angle of vanishing stability >= 25°, and GZmax >= 0.25 m) were evaluated for each case. Results indicate that the ballast condition yields the highest stiffness (GM approximately equal to 1.50 m) and energy absorption (AUC approximately equal to 1.15 mrad). The crane-outreach scenario represents the narrowest margin (GM approximately equal to 0.90 m, AUC approximately equal to 0.60 mrad). A safe-loading envelope was developed, showing permissible crane loads of up to 100 t at 10 m outreach and limiting lifts beyond 20 m to 50 t or less. Mitigation measures—ballast management, outreach/load restrictions, optimized cargo stowage, and real-time monitoring—are recommended to ensure regulatory compliance and operational safety.

Abstract

This study investigates the integration of a solar photovoltaic system on the passenger ferry E.V. Calestia operating along Manila’s Pasig River. The ferry, equipped with dual 400 kW electric motors and a battery bank of 1848 kWh, is supplemented by 20 solar panels installed on its top deck. Using a Simulink-based simulation model, the research estimates the power output and cumulative energy generation based on panel specifications, solar irradiance, and system efficiency. Results show a maximum instantaneous power output of approximately 3 kW during peak sunlight and a total weekly energy generation of around 150 kWh. These findings demonstrate the potential of solar power to enhance the ferry’s energy sustainability by reducing reliance on conventional charging and lowering emissions, thus promoting greener maritime transport solutions in urban river environments.
