Abstract

Outrigger boats are prevalent in Indonesian waters. In Indonesia, the majority of Outrigger boats have a gross tonnage of less than 7 GT, resulting in their classification as "boats." After being hit by waves, the outrigger serves as a balancing mechanism on the boat, ensuring that it does not capsize and that it continues to keep its stability. In spite of the fact that they have a number of benefits, outrigger boats also have a number of drawbacks. One of these drawbacks is that they need a mooring space that is sufficiently large to anchor the boat at the beach or pier. This research was carried out through the use of experimental methodologies. The stability value is a reference to the design parameters established by IMO A.749 (18), which are applicable to all boats. Type 2 boats have a maximum GZ value that is greater than that of type 1 boats. According to the findings of the study, the utilization of the Palabuhanratu pool was increased by 33% on model B boats and by 52% on boat C when the outrigger boom was pulled while the boat was in the port pool. This was in comparison to the original value when the boat was anchored without pulling the outrigger boom.

Abstract

Komodo National Park (KNP), a UNESCO World Heritage Site, faces significant environmental challenges due to increasing tourism, climate change, and resource management issues. This preliminary study employs the Contingent Valuation Method (CVM) to estimate visitors' willingness to pay (WTP) for adaptive management initiatives aimed at preserving the park's unique biodiversity and ecological health. Conducted in Labuan Bajo, the main gateway to KNP, the study involved 50 respondents who were surveyed on their WTP for improved environmental quality and management. The binary logistic regression analysis revealed that higher income levels and gender significantly influence WTP, with higher income individuals and males being more likely to contribute financially. Marital status showed a negative association with WTP, suggesting that married individuals may have financial constraints. The study highlights the importance of understanding sociodemographic factors to design effective funding strategies for conservation. The findings underscore the need for targeted communication and engagement strategies to increase financial support for adaptive management. These insights will inform policy and management strategies to ensure the long-term sustainability of KNP.

Abstract

The ship being analyzed is a Ferry ro-ro 2000 GT sailing from Bali to Lombok via the Lombok Strait crossing route with a distance of 38 nautical miles. Identification of the use of diesel fuel for ship operations is important for ferry vessels, especially in connection with efforts to efficiently use of diesel fuel in ship operations. In solving problems, efficiency analysis is completed by applying technical analytical, correlational-predictive, and comparative methods. The technical analytical method is specifically used to calculate engine characteristics in fuel use, and the correlational-predictive method is used as an approach method to the phenomenon of the relationship between engine characteristics in the use of different fuels in ship operations, in contrast, the comparative method approach will be used to provide a detailed illustration. More complete in a case study of the use of diesel as fuel for the operational main engine of a ferry ship.

Abstract

Vanadium Redox Flow Batteries (VRFB) have emerged as a potential solution for renewable energy storage due to their scalability and long lifetime. However, optimizing their operational efficiency and addressing the issue of parameter accuracy for the right load pose significant challenges. This paper aims to quantify the critical parameters of VRFBs and analyze their performance in powering the system under various flow rate operating conditions. Simulations are performed using MATLAB software and unit blocks to evaluate the behavior of VRFBs during discharge and charge conditions at three electrolyte flow rates: 10, 5, and 1 liter per minute (lpm). The analysis focuses on key parameters, including operating duration, charge/discharge time, and state of charge. The results show that higher flow rates increase the discharge duration, while lower flow rates lead to shorter operating times and more pronounced ripples caused by pump control instability and electrolyte density variations. Therefore, designing appropriate parameters in VRFB systems is critical to developing sustainable energy storage solutions and supporting the implementation of clean energy technologies.
