Abstract

Ship mooring at coral reef slope is a high risk for Indonesian coral reefs, particularly in tourist based coastal environment. Mooring buoy technology is a well-established component of offshore engineering but has not yet been fully adapted to shallow coral reef ecosystems. This bibliometric analysis of 2015-2024 publications was performed using Lens.org and VOSviewer in search of research trends and knowledge gaps. The study finds six main research clusters, including: environmental management, tourism, and technical aspects; conservation, ecosystem behaviour, and protected areas; sustainable development and threats; coral reefs and ecosystem resilience; fisheries and the deep sea; and sea monitoring and conditions. While coral reef conservation research also has good representation, the following are important gaps identified in this study: mooring technology is very isolated in its own network with little apparent influence on conservation or oceanographic fields. This reflects two major gaps: mooring technology are not associated with conservation objectives, and mooring designs have not been adapted to Indonesia’s unique oceanographic conditions. This research demonstrates that developing mooring buoys suitable for Indonesian shallow waters represents a strategic opportunity to bridge engineering with practical conservation. Future research should focus on three areas: site-specific hydrodynamic characterization at marine tourism destinations; numerical simulation of adaptive mooring designs; and community-based implementation frameworks for long term sustainability.

Abstract

Biofouling is a collection of unwanted living organisms on surfaces submerged in water. Biofouling is a complex occurrence caused by various physical and environmental factors that can be overcome by regular hull cleaning. The main purpose of underwater hull cleaning is to remove dirt and restore propulsion efficiency. Another benefit of hull cleaning against biofouling is to restore or rejuvenate the effectiveness of antifouling paint. This study aims to determine the extent of the effect of periodic hull cleaning on the underwater area, where the results can be used to determine the most efficient period for periodic hull cleaning and the percentage of fuel that can be saved by performing periodic underwater cleaning.The effect of biofouling can be predicted by conducting simulations using Computational Fluid Dynamics (CFD) with several variations in hull roughness. The results of the CFD simulation show that the increase in resistance with the largest surge occurs in the 18th period with an average increase of 5.8%. Therefore, the effective time to perform underwater hull cleaning is in the 18th period. Performing underwater hull cleaning in the 18th period can save fuel consumption by up to 5.8%.

Abstract

South Kalimantan has quite extensive peatlands, spread across various regions such as Barito Kuala, Banjar, Tapin, and Hulu Sungai Regencies. In these peatlands, gelam trees are often found growing rapidly and possessing various benefits, both for industrial and environmental purposes. With wise management, peat can be used as an environmentally friendly raw material for briquettes, while gelam wood can be utilized to improve the quality of the briquettes. In this study, mixed peat and gelam wood briquettes were made with various compositions (100%:0%, 80%:20%, 60%:40%, 50%:50%, 40%:60%, 20%:80%, and 0%:100%) and types of adhesives (palm sugar and damar resin). To determine the performance of the briquettes, physical characteristics were tested in the form of water content, ash content, volatile matter content, calorific value, and fixed carbon. Test results show that gelam increases the calorific value and volatile matter content but reduces the fixed carbon content, while peat increases the fixed carbon content but lowers the calorific value. Damar adhesive is superior in increasing calorific value and reducing ash content compared to palm sugar. The best briquette combination is ≥60% gelam with damar adhesive for fast, high-energy combustion. For slow, stable combustion, a dominant peat composition with damar adhesive is more suitable.

Abstract

The shipping industry is widely adopting appropriate technologies in various areas to overcome challenges and improve efficiency. However, ship loading and unloading efficiency remains a significant concern in terms of cost and time. Monitoring the loading and unloading process relies heavily on Android-based manual input calculations, indicating the potential for technological application in the draft survey process. This research initiates the development of an Internet of Things (IoT) application to monitor trim readings during the draft survey of a ship. The planning involved initial stability calculations to add data to the IoT module planning. The resulting tool aims to improve efficiency by providing real-time trim and ship balance data during loading and unloading operations. Additionally, this research demonstrates the potential of IoT technology in optimizing shipping logistics and can be further developed with more advanced technology to advance the maritime industry.

Abstract

The Indonesian archipelago is strategically located in the major vessels’ global routes and domestic shipping lanes that lead to dense ship traffic with a mix of challenging navigational conditions, which consequently raises the potential risk of maritime accidents. Modern navigational aids—and the systems used in maritime and aeronautical sectors are just two examples—are now widely recognised to be a key factor for increasing situational awareness, explaining better route planning and decreasing instances of collisions or other hazards. This research assesses the role of these technologies to enhance safety in Indonesian waters and explores legal frameworks for their introduction. Through a descriptive/analytical approach supported by regulation review and literature analysis, the study recognizes existing advantages provided modern navigation systems, in real time monitoring and hazards detection in particular. Several challenges remain, however, with the uneven technological uptake among ships and ship types, limited seafarer skills, insufficient navigational infrastructure and evidence of unsafe operation such as AIS switching off. Regulatory loopholes and insufficient harmonization with international regulations (SOLAS, MARPOL, IMO, STCW) also have impacts on the overall effectiveness of navigation technologies. It is concluded that modern navigation systems greatly contribute towards the safety of maritime navigation, but their full utilization will have to be supported by better enforcement of regulations, upgrading infrastructure, regular training of crews and harmonization with national e-navigation initiatives. Recommendations and research directions are suggested in the evaluation to enhance an effective and technological-based maritime safety system in Indonesia.

Abstract

The potential of marine, fisheries, and tourism resources in Tapanuli Tengah Regency is increasingly threatened by the growing accumulation of unmanaged waste. Piled-up waste in coastal settlements, mangrove forest areas, and marine waters has caused severe degradation of coastal ecosystems and a decline in environmental quality. This study aims to identify the types of waste found in the coastal and marine areas of Tapanuli Tengah Regency and to formulate relevant waste management strategies to preserve the marine environment while improving the economy of fishing households. This research employs a case study method with qualitative descriptive analysis and SWOT analysis. The findings indicate that inorganic waste—particularly plastic—dominates the coastal and marine areas, followed by styrofoam, baby diapers, and fabric waste. These types of waste were found accumulating at the research locations: Mela I Village, Pondok Batu Village, Hajoran Village, and Jago-Jago Village. Based on the SWOT analysis, several recommended waste management strategies include environmental awareness and education programs for coastal communities, the development of facilities for sorting organic and inorganic waste, the establishment of Waste Banks at the village or sub-district level, the development of handicrafts made from plastic waste, composting of organic waste, and regular community-led “clean and waste-free sea” activities initiated by the local government and residents. These strategies are expected to support marine conservation and strengthen the economic resilience of fishing families.

Abstract

Teloko Lake in Ogan Komering Ilir, South Sumatra, is a peat swamp ecosystem revitalized through dredging to increase water storage capacity and reduce flood risk. This study analyzed post-revitalization sedimentation, assessed water quality, and identified suspended particle characteristics to support lake management. Objectives included determining the distribution of Total Suspended Solids (TSS), sedimentation rates, and relationship between particle properties and hydrological conditions to assess revitalization impact. Sampling was located at five locations at depths of 0.68 to 1.30 meters during dry season in September 2025. TSS concentrations ranged between 681 and 740 mg/L, with an average of 710.92 mg/L and a standard deviation of ±9.6%, indicating uniformity across locations and no significant dredging impact. A 72-hour sedimentation test showed a very low settling rate, with particles remaining suspended without forming a clear sediment layer. This is due to the dominance of colloidal particles less than 20 µm, containing positively charged organic matter, creating repulsive forces that inhibit natural sedimentation. The results confirm natural peat water properties and lake activities have a stronger influence on sedimentation than technical revitalization. These findings support long-term conservation by recommending ecological approaches, such as natural coagulants, to maintain water storage capacity and preserve ecosystem function.

Abstract

Hybrid propulsion systems, integrating internal combustion engines with electric motors, represent a significant advancement in maritime technology, offering improved efficiency and reduced emissions. However, their complexity introduces challenges in maintenance and reliability. Traditional maintenance strategies are often inadequate for these dynamic systems, leading to unplanned downtime and increased costs. This research develops and validates a predictive maintenance framework specifically designed for hybrid propulsion systems in maritime applications, integrating vibration, thermal, and electrical data to enhance system reliability and reduce maintenance costs. The study employs advanced signal processing techniques including Root Mean Square (RMS), Kurtosis, Fourier’s Law, and Wavelet Transforms to extract degradation features from sensor data. Multi-sensor fusion is achieved using Dempster-Shafer evidence theory and weighted entropy-based models to resolve data conflicts and provide a holistic health assessment. Failure prediction and Remaining Useful Life (RUL) estimation are conducted using Proportional Hazards Models (PHM) and Weibull distributions. The framework was validated through case studies on two hybrid-powered vessels: a 2 MW coastal cargo ship (Ship A) and a 5 MW offshore support vessel (Ship B). Results showed that Ship A achieved an MTBF of 1,440 hours and 99.45% availability, while Ship B, operating under harsher conditions, recorded an MTBF of 864 hours and 99.08% availability. The PHM-based RUL estimation achieved a Mean Absolute Error of 12.5 hours (15.6% error), demonstrating high predictive accuracy. Economic analysis indicated a potential 40% reduction in annual maintenance costs compared to traditional methods.

Abstract

The implementation of exhaust gas cleaning systems (scrubbers) has become a critical compliance strategy for maritime vessels following the International Maritime Organization's 2020 Global Sulphur Limit regulation. However, the technical relationship between scrubber performance and main engine operational reliability remains insufficiently documented in empirical maritime research. This study aims to analyze the correlation between scrubber performance and engine operational performance on the container vessel MV. Sinar Sorong through a quantitative approach utilizing technical parameter measurements and structured questionnaires. Data were collected during operational periods from April to December 2025, encompassing chemical performance parameters of coagulant and flocculant agents, engine performance metrics including maximum combustion pressure, compression pressure, exhaust gas temperature, and specific fuel oil consumption. The research employed 29 respondents from the engine department selected through purposive sampling technique, with data analyzed using Pearson correlation and linear regression in SPSS version 26. Results demonstrate a positive and statistically significant correlation (r = 0.587, p = 0.001) between scrubber performance and engine operational performance, with regression analysis indicating that 96.9% of engine performance variance can be explained by scrubber efficiency. The scrubber system maintained optimal technical parameters with nonvolatile solid content of 34.1%, viscosity of 420 cPs, basicity level of 40%, and pH range of 3.5-8.2, effectively reducing sulfur oxide emissions while maintaining engine stability. Main engine parameters remained within optimal design specifications: maximum combustion pressure 145.4 bar, compression pressure 107.2 bar, exhaust gas temperature 333°C, and specific fuel consumption 174.0 g/kWh. This research contributes empirical evidence that scrubber systems function beyond regulatory compliance instruments, serving as technical components that enhance combustion system stability through sulfur residue reduction and corrosive deposit prevention in exhaust pathways. The findings provide practical implications for maritime operators to implement integrated preventive maintenance strategies and real-time monitoring systems to sustain the synergistic relationship between scrubber efficiency and engine reliability, ultimately optimizing operational efficiency and extending critical component lifespan.

Abstract

This paper presents an experimental optimization of R-134a refrigerant charge mass in a retrofitted dual function vapor-compression refrigeration system designed to operate in Air-Side (AHU) and Water-Side (Water Chiller) modes. The system was evaluated after retrofit by testing four charge levels—399.5 g (85%), 423.0 g (90%), 446.5 g (95%), and 470.0 g (100%)—under multiple operating conditions: three fan speeds for AHU mode and chilled-water flowrates of 6 8 L/min for chiller mode. Performance was quantified using evaporator capacity Qevap, condenser heat rejection Qcond, compressor electrical power (PcompP_{comp}Pcomp), coefficient of performance (COP), and energy efficiency ratio (EER). The results show that the optimal charge is mode- and objective-dependent. In AHU mode, the maximum cooling capacity was obtained at 470 g (100%), reaching Qevap=4.58 kW, while the highest COPactual=3.1234 occurred at 423 g (90%), accompanied by the lowest AHU compressor power Pcomp=1.722 kW). In Water-Side mode, the highest cooling capacity was achieved at 446.5 g (95%), with Qevap=5.141 kW at 6 L/min, whereas the best energy-utilization outcome occurred at 470 g (100%) and 6 L/min, yielding EER = 2.888 with the lowest chiller compressor power Pcomp=1.6524 kW). Overall, the study provides a practical, mode-aware guideline for selecting refrigerant charge in retrofitted dual-function systems for marine engineering applications.
