Abstract

Indonesia as the largest archipelago with abundant potential fishery resources contributes to national foreign exchange (Damayanti & Sugiarto, 2022). One of the main commodities of fishery products commonly exported by Indonesia is shrimp (Dewi et al., 2022). Increasing shrimp production through intensive aquaculture faces the challenge of disease, especially Vibrio sp. bacterial infection. The use of antibiotics as a general solution raises resistance problems, so alternatives such as probiotics are needed. Lactic acid bacteria (LAB) are potential candidates for probiotics because of their ability to produce organic acids that inhibit the growth of pathogenic bacteria. This study aims to analyse the characteristics of LAB from Sidoarjo shrimp petis, a typical fermented product that has potential as a source of LAB, and test its antibacterial ability against Vibrio sp. The stages carried out in the study consisted of 5 stages including the first stage of sampling, the second stage of lactic acid bacteria isolation, the third stage of characterisation of lactic acid bacteria isolates, the fourth stage of lactic acid bacteria antibacterial test, and the fifth stage of data analysis. The results showed the total colonies of Lactic Acid Bacteria (LAB) in the six isolates with a value of 7.08 x 106 colonies.mL. LAB characteristics on the six isolates consisted of macroscopic, microscopic, and biochemical characteristics. Microscopic characteristics of the six isolates showed the same results, namely round, white colour, flat and convex elevation, and smooth edges. Microscopic characteristics of the six isolates showed the same results, namely bacillus and gram-positive cell forms. Biochemical characteristics on the six isolates showed different results. Antibacterial tests were carried out after knowing the type of lactic acid bacteria isolates through several characteristic tests, it can be seen that there are 4 isolates including isolates PTS.5.1, PTS.5.2, PTS.6.1, and PTS. 6. 6. The results of antibacterial tests on 4 isolates have antibacterial compounds in inhibiting the growth of gram negative bacteria (Vibrio sp,). Seen the results obtained isolates that have the greatest antibacterial activity is PTS.5.1 with a final result of 10.2625 mm.

Abstract

The ballast control management system plays a vital role in maritime operations by ensuring vessel stability and safety while minimizing environmental risks associated with ballast water transfer. Effective ballast management regulates the filling and emptying of ballast tanks to maintain proper trim, draft, and balance during navigation and docking. With the enforcement of the Ballast Water Management (BWM) Convention by the International Maritime Organization (IMO), vessels must implement a Ballast Water Management Plan (BWMP) and maintain a Ballast Water Record Book to comply with international regulations. This study aims to develop a PLC- and HMI-based ballast control system that enhances monitoring and automation of ballast operations. The system is designed to improve control accuracy, diagnostic capabilities, and operational flexibility while ensuring compliance with IMO regulations. The research methodology involves system design, hardware integration, and software programming to create an automated control and monitoring solution. The PLC system utilizes digital inputs to operate pumps and valves, while analog sensors measure tank levels and pressure. The HMI interface displays real-time data, enabling seamless user interaction. The results demonstrate that the proposed system significantly enhances ballast operations by improving automation, control accuracy, and monitoring capabilities. The system ensures safe and efficient ballast management while facilitating regulatory compliance. These findings highlight the potential of PLC and HMI technologies in advancing maritime automation and control systems.

Abstract

Mangrove ecosystems are important in carbon sequestration and climate regulation and contribute to climate change mitigation. However, carbon stock estimation is still mostly done manually, which is less efficient. This study utilizes remote sensing to investigate the correlation between mangrove carbon stocks and climate variability in West Java from 2019 to 2023. Mangrove land cover classification was performed using the Random Forest algorithm with NDVI and NDWI indices, while the relationship between carbon stock and climate factors was analyzed using linear regression. The results showed that increased precipitation was associated with higher carbon stocks (R2=0.5514), while carbon stocks had a negative correlation with 2-meter temperature (R2=0.8242) and sea surface temperature (SST) (R2=0.7111). This study enhances our understanding of mangrove-climate interactions and provides valuable insights for developing remote sensing-based climate resilience and coastal ecosystem management policies.

Abstract

The premium of Indonesian marine insurance is one of the issues for maritime players in Indonesia, particularly for passenger vessels. Indonesian government also released some policies as a part of positive initiatives to bring Indonesia to the next level of maritime involvement in the world, however, the insurance side as the main risk protection of maritime operation is not positioned as the main part to be discussed. Marine insurance is the key to managing the overall risk of the passenger vessels during the operation. In fact, in Indonesia, insurance studies still have a gap in their application, particularly for the marine insurance industry and for passenger vessel insurance. The underwriter has difficulties in assessing the real risk of Indonesian passenger vessels while the shipowners do not put safety as their top priority in managing the business. This research aims to solve two main problems in Indonesian passenger vessel insurance; the first one is to identify the problems of Indonesian passenger vessel insurance and the second is to explore and identify the premium factors of Indonesian passenger vessel insurance. The study found that the big claim ratio reported over the years, the lack of marine insurance underwriters’ ability to assess the risk, the lack of marine insurance capacity, and the premium war are the main problems faced by Indonesian passenger vessel insurance players. Accordingly, this paper is also revealing several premium factors for Indonesian passenger vessel insurance; including the vessel type, GT, claim record, years of built, trading area, extent of insurance coverage, vessel condition, as well as the moral hazard from the owner and the crew.

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

In sustainable development, Green Tourism integrates environmental preservation, community empowerment, and tourism attractions. This paper aims to develop a strategy for integrating Green Tourism into Tapanuli Tengah Regency's maritime tourism industry. This area continues to deal with a number of classic challenges, such as disorganized tourism administration, poor waste management, and a disregard for accommodations and accessibility. A comprehensive review of the regulations that were implemented in place is backed by a mixed methodology that uses the Soft System Methodology for Visitor Satisfaction Index (VSI) values and responses from different respondents. The research findings, with a satisfaction level of 80.4%, demonstrate that tourists are happy with the tourism activities. There are nonetheless, certain demands made by the guests. Planning for a more methodical and sustainable development necessitates careful consideration of current policies.The research findings outline a number of issues and their resolutions, such as the creation of first-rate amenities, instruction for operators of tourism-related businesses, the application of standard operating procedures (SOP) to ensure price parity for goods and services, and a recommendation to launch a flight route from Jakarta to Tapanuli Tengah in order to facilitate outside tourists coming to the region.

Abstract

Medium voltage (MV) switchgear at 20 kV, known as Panel Hubung Bagi (PHB) 20 kV in Indonesia, is a critical component of the electrical power distribution system, containing fuses, switches, and power conductors. A failure in this switchgear could lead to system-wide malfunctions, with potential catastrophic consequences such as fires or explosions. To prevent such events, it is essential to perform regular and well-planned maintenance. This research aims to optimize the maintenance process for MV switchgear, focusing on reducing maintenance tasks and frequency without compromising system reliability. The study employs the Failure Mode and Effect Analysis (FMEA) methodology, refined to reduce unnecessary maintenance actions. A Systematic Literature Review (SLR) was also conducted to analyze previous research on FMEA applications in 20 kV MV switchgear maintenance. Traditionally, maintenance was guided by manufacturers' recommendations, experience, and technical judgment, resulting in 3554 man-hours (MH) of labor every two years. However, by applying the refined FMEA process, maintenance requirements were significantly reduced to just 212 MH over the same period. This reduction represents a cost saving of 1678%, while still ensuring that the reliability of the MV switchgear at 20 kV is maintained at a high level. These findings underscore the importance of adopting systematic maintenance approaches to improve operational efficiency and reduce costs in power distribution systems.
