Abstract

Floater is one of the most important part of amphibious version plane and conducting study of it becomes one of the featured research to support Indonesia’s transportation. This paper examined general study of amphibious floater slamming load when landing on the water in the various plane landing situation, starting from stern 5°, stern 10°, bow 5°, bow 10°, heel 0°, heel 5° and heel 10°. Carbon Fiber Reinforced Polymer (CFRP) material is used with 20 and 40 mm thickness. Floater consists of three main parts which are base, keel, and frame. Seaplane is designed to withstand 1000 cycle (500 landing and 500 take off cycle) in a year. This paper confirms that with the thickness of 20 and 40 mm, and heel position of 0°, floater can withstand up to 65,535 years. In contrary, using the 20 and 40 mm layer when landing with any combination position, the floater can’t last and only has 0.01 year of fatigue life.

Abstract

Abstract¾ Indonesia is one of the world’s leading producers and exporters of fresh and frozen fish; however, the economic value of its fishery exports remains relatively low due to quality deterioration caused by inadequate post-harvest handling, particularly during onboard storage. Small-scale fishers predominantly use conventional storage media such as styrofoam or fiber-based cool boxes with block ice, which often provide insufficient insulation and poor temperature stability. This study aimed to evaluate the thermal performance and ice utilization efficiency of an innovative laminated cool box constructed using a combination of aluminum plate, aluminum foil, ethylene-vinyl acetate (EVA) sponge, and fiberglass, compared with a conventional fiber-based cool box. An experimental design with two treatments and three replications was applied over a four-month period at the Capture Fisheries Laboratory, Politeknik Negeri Lampung. Cooling performance was assessed through optimal cooling tests, 24-h and 48-h temperature performance evaluations, ice efficiency analysis, and statistical comparison using an independent samples t-test. The results showed that the innovative cool box achieved a lower minimum temperature (−3 °C) and a faster cooling rate (0.50 °C min⁻¹) than the standard cool box (−1 °C; 0.29 °C min⁻¹). During the 48-h test, the innovative cool box maintained temperatures below 4.4 °C for up to 18 h, significantly longer than the standard cool box. Although the ice utilization efficiency of the innovative cool box (26.16%) was lower than that of the standard cool box (30.80%), its overall cooling performance and thermal stability were superior. These findings demonstrate the potential of the innovative cool box to improve fish quality preservation and support higher economic value in fisheries post-harvest handling.

Abstract

Occupational fatigue in construction projects remains a critical safety issue, yet its assessment is commonly based on subjective questionnaires and interviews that may not accurately reflect real-time physiological performance. This study aimed to analyze the relationship between biological factors and work-related factors and the level of work fatigue among construction workers using Digital Reaction Timer measurement as an objective indicator. A cross-sectional study was conducted involving active construction workers, where fatigue was quantified using a digital reaction timer as an objective human performance indicator. Biological factors such as age, gender, sleep duration, and nutritional status, as well as work-related factors including working hours, shift patterns, workload, and work experience, were statistically analyzed against reaction time results. The findings show that reaction time measurement can differentiate fatigue levels and identify significant determinants affecting performance degradation. Several biological and occupational variables were associated with increased reaction time, indicating higher fatigue levels. The results demonstrate that an engineering-based digital measurement approach provides a more objective and quantifiable fatigue assessment compared to traditional self-reported methods, supporting data-driven safety management in high-risk construction environments.

Abstract

The Indonesian Government has implemented the Measured Fishing Policy (PIT) through Government Regulation No. 11 of 2023 as an effort toward sustainable fisheries management. This policy regulates measured fishing according to fish resource potential within each Fisheries Management Area of the Republic of Indonesia (WPPNRI). The PIT policy has been applied in several regions, including Banda Aceh City, yet faces challenges such as limited port infrastructure, low local fishers’ awareness, and a lack of empirical data on its impacts on fishing productivity and welfare. This study aims to analyze changes in the productivity and income of tuna, skipjack, and frigate tuna fishers before and after PIT implementation in Banda Aceh. A mixed-methods approach was employed, combining production and fishing effort data from the Kutaraja Ocean Fishing Port (PPS Kutaraja) with in-depth interviews with fishers and stakeholders. Results show that tuna production peaked in 2024 at 395.35 tons/year and was lowest in 2021 at 33,99 tons/year. Skipjack production reached 1.502,79 tons/year, while frigate tuna production was highest in 2024 and lowest in 2022 (75.15 tons/year). Income analysis revealed that purse seine fisher’s profits were influenced by vessel, engine, gear investments, and operational and maintenance costs. In conclusion, the PIT policy affects the dynamics of local fishers’ productivity and income, providing an empirical basis for strengthening sustainable fisheries policy at the local level.

Abstract

The increasing use of electric forklifts in industrial environments requires charging power supply systems that are technically reliable and compliant with updated electrical safety regulations. However, empirical studies evaluating the regulatory compliance and safety risks of electric forklift charging panels—particularly under Indonesia’s Minister of Energy and Mineral Resources Regulation No. 1 of 2023—remain limited, indicating a clear research gap. This study aims to assess the compliance level of an existing electric forklift charging power supply panel and to propose a redesigned panel that meets regulatory and safety requirements. An observational assessment was conducted using a structured compliance checklist derived from ESDM Regulation No. 1 of 2023, covering protection systems, grounding, monitoring instruments, labeling, and operational safeguards. Quantitative compliance scoring and risk-based evaluation were applied to identify technical deficiencies and associated electrical hazards. The results show that the existing panel complies with only 58% of mandatory requirements and presents several high-risk conditions, particularly due to inadequate protection devices, lack of electrical monitoring, and insufficient grounding. A redesigned single-line diagram was subsequently developed and evaluated, achieving 100% compliance with mandatory and recommended criteria. The proposed design significantly reduces electrical safety risks, improves system reliability, and ensures full regulatory compliance, providing a practical reference for the development of safe and reliable industrial electric vehicle charging infrastructure.

Abstract

Boilers experience frequent problems, such as scale formation, unstable steam pressure, incomplete combustion, and difficulty starting. Therefore, this study uses a quantitative method with the Failure Mode and Effect Analysis (FMEA) approach, which aims to determine maintenance and prevention to minimize these problems. This method determines the failure priority obtained from the Risk Priority Number (RPN) calculation based on assessment factors such as severity, frequency of occurrence, and the likelihood of failure being detected in each component. The results of these calculations indicate that the steam drum component falls into the highest category, with an RPN of 32. The other 12 components fall into the medium category: the feed water pump, electrode, photocell, nozzle, blower fan, solenoid valve, fuel pump, blowdown valve, main steam valve, scum valve, non-return valve, and gauge glass, with RPN values ranging from 12 to 24. Furthermore, the components in lowest category include the fuel filter, safety valve, and manometer, with RPN values ranging from 8 to 10. Therefore, the recommended improvements based on the FMEA results can be used as evaluation material to ensure the effectiveness of the improvements. Furthermore, regular boiler maintenance and monitoring are required, especially for components such as the steam drum, which requires additional routine maintenance schedules, repeated evaluations related to water treatment, and determining appropriate repairs for any steam drum failures.

Abstract

The management of ship administrative systems in maritime education institutions remains predominantly manual, fragmented, and vulnerable to documentation errors, certification lapses, and operational inefficiencies. As training vessels serve both educational and operational functions, ineffective administrative processes may disrupt academic activities, regulatory compliance, and maintenance scheduling. This study aims to design and evaluate a digital ship administrative management system to enhance operational efficiency and regulatory compliance in maritime education institutions. The research adopts a system development approach consisting of requirement analysis, system architecture design, prototype development, and performance evaluation. The proposed system integrates digital certificate monitoring, automated expiry notifications, document tracking, and a centralized dashboard for real-time administrative status monitoring. System performance is evaluated using operational efficiency indicators, including document processing time, error reduction rate, and administrative readiness level. The results demonstrate that the implementation of the digital administrative system significantly improves document accessibility, reduces processing delays, and enhances compliance monitoring. The centralized dashboard enables proactive decision-making and minimizes the risk of certification expiration. This study contributes to maritime engineering management by providing a practical digital transformation framework tailored for maritime education institutions, supporting the transition toward smart maritime governance and Industry 4.0 practices.

Abstract

The tsunami disaster in the Indian Ocean on 26 December 2004 had an impact that killed more than 300,000 worldwide and caused catastrophic damage to infrastructure. Indonesia is a tsunami-prone country because it is located between two plates that have great potential for collision, that are the Eurasian plate and the Indo-Australian plate. One of the efforts to mitigate the tsunami disaster is to create protection in the form of natural protection (coastal forests). Tsunamis that move closer to the coast are in the form of surge waves similar to waves resulting from a dam break. The change in depth from the deep sea towards the coast results in an increase wave height, but a decrease in wave velocity. This research was conducted using a physical model simulation approach in the laboratory, using a dam break-based tsunami wave generation method by making a simulation of the flume used measuring 16.80 m x 1.0 m x 0.8 m equipped with a dam break gate. Making a model of a casuarina forest is done by observing and measuring tree dimensions, plant spacing and density. The research results show that there was a decrease in water velocity for the tsunami model d0 = 60 cm for the model without canopy 1 m is 21.09%, 2 m is 29.36%, and 3 m is 36.50%. The decrease surge velocity due to the model with canopy 1 m is 21.71 %, 2 m is 29.67 %, and for 3 m is 40.40 %. For the velocity function to be changed to f V (m, L, n, x). The tree canopy effect is quite effective for high tsunamis but for low tsunami it is not effective, because the tsunami surge will propagate through the tree trunks below canopy.

Abstract

The reliability of naval propulsion systems is closely related to the degradation of critical gas turbine components, particularly the compressor and turbine. This study proposes a machine-learning-based predictive health monitoring framework for a naval propulsion plant using the Naval Propulsion Plant dataset. The framework was developed from 11,934 observations, 14 operational variables, and 2 degradation targets, namely the compressor decay state coefficient and turbine decay state coefficient. A multi-output Random Forest regressor with 500 trees was employed to simultaneously predict both degradation indicators. The methodology included data preprocessing, exploratory data analysis, model development, performance evaluation, feature importance analysis, and health index formulation. The model achieved an MAE of 0.1899, RMSE of 0.2992, and R² of -0.0484 for the compressor decay state coefficient, while the turbine decay state coefficient achieved an MAE of 0.1604, RMSE of 0.2667, and R² of 0.1814. To improve practical interpretability, the predicted degradation outputs were transformed into a health index and classified into GREEN, YELLOW, and RED conditions. The results showed that 2,387 testing observations were classified as GREEN. The novelty of this study lies in integrating multi-output degradation prediction, feature-based interpretability, and health-index-based condition classification within a single predictive maintenance framework for naval propulsion systems.

Abstract

Climate variability is increasing the vulnerability of small-scale fishing communities, especially in coastal areas that are highly dependent on fishery resources as their main source of livelihood. This study aims to identify fishermen's adaptation mechanisms, analyze their level of resilience, and determine the factors that influence the resilience of small-scale fishermen in two coastal villages in Central Tapanuli Regency, namely Teluk Roban Village and Pasar Sorkam Village. This study uses a quantitative survey approach with purposive sampling techniques on 70 fishing households consisting of 35 fishermen in Teluk Roban Village and 35 fishermen in Pasar Sorkam Village. The data were analyzed using statistical analysis to identify factors that influence the resilience of fishing households. The results of the study show that the resilience of fishing households in Teluk Roban Village is significantly influenced by education levels, access to financial institutions, livestock ownership, and the size of the fishing fleet. Meanwhile, the resilience of fishing households in Pasar Sorkam Village is more influenced by the age of the head of the family, non-fishing income and access to natural capital such as mangrove forests, rice fields, and mango and coconut trees. Despite differences in livelihoods, the level of resilience of fishing households in both villages does not show significant differences and is generally in the moderate category. These findings indicate that diversification of livelihoods, access to financial resources, and utilization of natural capital are important factors in strengthening the adaptive capacity of fishing households to climate variability.
