Abstract

Intensive culture of Nile tilapia in saline environments often faces major constraints, including water quality deterioration, proliferation of Vibrio spp., and physiological stress that impairs growth performance. Plant-based materials have recently gained attention as sustainable additives to improve aquatic environments and enhance fish health. This study aimed to evaluate the effects of chopped banana stem, taro leaves, and their combination on water mineral composition, Vibrio spp. abundance, blood glucose levels, and growth performance of Nile tilapia reared in saline conditions. The experiment was conducted over 30 days using four treatments: control (CO), banana stem (BS), taro leaves (TL), and their combination (BT, 1:1), each applied at a dose of 5 g/L with three replicates. Fifteen tilapia fingerlings were stocked in each container. The results showed that the application of plant materials significantly increased water mineral concentrations compared to the control. The BS treatment resulted in a significant reduction in Vibrio spp. abundance. Blood glucose levels remained relatively stable across all treatments. Growth parameters, including final weight, weight gain, and daily growth rate, were significantly improved in the treated groups, although survival rate did not differ significantly. Overall, the application of banana stem and taro leaves improved water quality, suppressed Vibrio spp. abundance, maintained physiological balance, and enhanced the growth of Nile tilapia.

Abstract

Keumamah, a traditional Acehnese processed fish product, holds significant economic and cultural value; however, the implementation of quality assurance and food safety systems among micro, small, and medium enterprises (MSMEs) remains challenging. This study aimed to evaluate the quality of keumamah produced by MSMEs in Banda Aceh City based on four key parameters: sensory attributes, moisture content, total plate count (TPC), and mercury (Hg) levels, in accordance with applicable national standards. A total of six MSMEs three small-scale and three micro-scale were selected using quota sampling. Sensory evaluation based on SNI 2346:2015 revealed that all samples achieved mean scores of ≥ 7 (scale 1–9) across appearance, odor, taste, and texture parameters, indicating compliance with sensory standards. Moisture content analysis based on SNI 9194:2023 showed that only one of six samples complied with the maximum allowable limit of ≤ 60%, while the remaining five exceeded this threshold. TPC analysis based on SNI 2332.3:2015 indicated that all samples surpassed the maximum limit of 10⁶ CFU/g, reflecting non-compliance with microbiological quality standards. Conversely, Hg levels in all samples were below the maximum permissible limit of 1.0 mg/kg based on SNI 01-2891-1992, confirming saf   ety with respect to heavy metal contamination. In conclusion, keumamah products from MSMEs in Banda Aceh City meet sensory and heavy metal safety standards but fail to comply with moisture and microbiological requirements. Improvements in processing practices particularly in drying, sanitation, and hygiene are urgently needed to enhance overall product quality and safety.

Abstract

Coliform contamination in fishery products may indicate inadequate hygiene and sanitation practices during the production process, which can potentially reduce product quality and food safety. This study aimed to analyze coliform contamination, identify the factors causing contamination, and evaluate the influence level of each factor using a Likert scale on ground meat tuna products during the processing stages at PT Samudra Ulam Nusantara. Coliform testing was conducted at several production stages, namely receiving, retouching, and grinding using the AOAC 991.14 method. The test results were analyzed using Statistical Process Control (SPC) and process capability analysis to evaluate process stability and the ability of the process to meet the specification limit of ≤100 CFU/g.  In addition, causative factor analysis was carried out using the fishbone (5M) approach, and perception evaluation was conducted through a Likert scale questionnaire. The results showed that coliform contamination increased significantly throughout the production stages, particularly during the retouching and grinding processes, indicating the occurrence of contamination during production activities. SPC analysis revealed that the process was statistically out of control, with a Process Capability (Cp) value of 0.12 and a Process Capability Index (Cpk) value of -0.29, indicating that the process was not capable of consistently meeting the established quality standards. Based on the Likert scale analysis, the method factor was identified as the most dominant factor influencing coliform contamination with an index value of 96%, followed by the man factor at 92% and the environment factor at 86%, while the machine and material factors contributed 76% and 54%, respectively. Based on these results, the increase in coliform contamination in ground meat tuna products was influenced by work methods, worker hygiene, and production environmental conditions. Therefore, improvements in SOP implementation, worker hygiene, temperature control, and production sanitation are necessary to improve product quality and safety.

Abstract

Along with advancements in mechanical engineering technology for fishing vessel, particularly in diesel engines, numerous developments have been made to achieve maximum performance. This study aims to determine the effect of applying an exhaust gas recirculation (EGR) system on the performance of diesel engines using B40 biodiesel fuel. The use of biodiesel as an alternative fuel is growing because it can reduce dependence on fossil fuels and reduce exhaust emissions. However, the use of high-blend biodiesel such as B40 can affect combustion characteristics and engine performance. Therefore, a method is needed to optimize engine performance, one of which is through the application of an EGR system. The research method was conducted experimentally by testing diesel engines using B40 biodiesel fuel. The testing was carried out directly by operating diesel engines equipped with EGR systems. The parameters observed included engine performance, such as power and specific fuel consumption. Data was collected under varying load conditions. The data obtained was then analyzed to determine the effect of EGR on engine performance improvement. The results indicate that the application of an exhaust gas recirculation system in diesel engines utilizing B40 biodiesel fuel can influence the combustion process, thereby affecting engine performance. At a valve opening of 25%, the best SFOC can be achieved. The results showed that the application of an exhaust gas recirculation system in diesel engines using B40 biodiesel fuel can affect the combustion process, thereby impacting engine performance. Based on the test results, it can be concluded that the application of an exhaust gas recirculation (EGR) system in diesel engines fueled by B40 biodiesel improves engine efficiency.

Abstract

Environmental disputes in Indonesia's coastal and marine areas have become increasingly complex due to the interaction of ecological, social, economic, and governance dimensions. While litigation remains an available legal mechanism, non-litigation environmental dispute resolution has gained greater attention because of its flexibility, participatory nature, and potential to facilitate environmental restoration. However, the effectiveness of non-litigation mechanisms remains influenced by various supporting and constraining factors that have not been comprehensively integrated into a single analytical framework, particularly in the context of coastal and marine environments. This study aims to analyze the factors influencing the effectiveness of non-litigation environmental dispute resolution in Indonesia's coastal and marine areas and to develop a preliminary conceptual framework for understanding their interrelationships. The research employs a normative legal approach with a conceptual research design, utilizing statutory, conceptual, and literature-based analytical approaches. Data were collected through an extensive review of legal documents, scientific literature, policy reports, and environmental governance studies relevant to environmental dispute resolution.  The findings indicate that the effectiveness of non-litigation environmental dispute resolution is supported by institutional capacity, regulatory support, multi-stakeholder participation, social trust, scientific evidence, and environmental governance quality. Conversely, power asymmetry, institutional limitations, weak implementation of agreements, political and economic intervention, and low environmental legal literacy constitute major barriers to effective dispute resolution. Based on the synthesis of these factors, this study proposes a preliminary conceptual framework that integrates legal foundations, institutional capacity, stakeholder participation, scientific evidence, ADR process quality, and environmental restoration as key determinants of dispute resolution effectiveness.  The study contributes to the development of environmental dispute resolution scholarship by offering an integrative conceptual perspective that may serve as a foundation for future empirical research and policy development in coastal and marine environmental governance.

Abstract

Small-scale capture fisheries in Demak Waters, Central Java are indicated to have experienced overfishing. Overfishing conditions will affect the decline in fishermen's income. This study aims to determine the bioeconomic conditions of small-scale capture fisheries and determine the income of small-scale fishermen in the waters of Demak Regency. The data collection method used a survey with 100 fishermen as respondents with a ship size <5GT. The study was conducted for 6 months from April to October 2024. The bioeconomic analysis of fisheries used the Gordon Schaefer surplus production method and income analysis used business analysis. The results of the study showed that overfishing and overcapacity had occurred since 2015, causing actual production to always exceed sustainable production, causing the actual catch to decrease by 1.93 million kg from what should have been 5.4 million kg. Fisheries rents also decreased from 93.15 billion rupiah to 32.98 billion rupiah. This is also reinforced by the income of ABK fishermen of 1.44 million per month or only 52.22% of the Demak UMK. The income of ship owners is also only 67.32% of the Demak UMK. This shows that capture fisheries need policy breakthroughs to improve the condition of small-scale capture fisheries in the waters of Demak Regency.

Abstract

Coastal and marine ecosystems provide critical economic, ecological, and social benefits, yet they continue to experience accelerated degradation driven by sectoral governance, weak enforcement, and persistent environmental conflicts. Over the past decades, ecosystem service valuation has generated substantial evidence on the economic significance of coral reefs, seagrass, mangroves, and fisheries. However, this evidence has rarely been translated into effective policy action, legal enforcement, or preventive governance mechanisms. This paper addresses this gap by examining how ecosystem valuation can evolve from a descriptive economic tool into a foundational element of transformational coastal and marine governance.  Using an interdisciplinary policy-oriented approach, this study synthesizes advances in ecosystem valuation, social-ecological systems (SES) analysis, marine audit practices, fisheries bioeconomics beyond maximum sustainable yield (MSY), and ethical governance instruments. Drawing on empirical and policy-relevant experiences from Indonesian coastal and marine contexts, including ecosystem damage claims, zoning violations, fisheries overexploitation, and valuation-based legal processes, the paper demonstrates both the achievements and limitations of valuation in influencing governance outcomes.  The results highlight that valuation becomes policy-relevant only when embedded within an integrated governance architecture. Marine audit is identified as a key institutional innovation that operationalizes valuation as an early detection, compliance monitoring, and conflict prevention mechanism. Furthermore, extending fisheries management toward maximum economic yield (MEY), welfare-oriented indicators, and ecosystem approach to fisheries management (EAFM) strengthens the linkage between economic efficiency, social equity, and ecological sustainability. The incorporation of ethical and social finance instruments, such as sharia-based fisheries management, zakat-infaq-shadaqah (ZIS), and waqf-based conservation models, provides long-term financing mechanisms and normative legitimacy for sustainable resource governance.  This paper proposes a transformational governance framework built on four integrated pillars: ecosystem valuation, SES-based system understanding, marine audit and legal enforcement, and ethical finance and social innovation. Policy implications emphasize the need for mandatory valuation in marine spatial planning and licensing, institutionalized marine audit systems, valuation-based legal standards, and preventive governance strategies. The framework offers a practical pathway for bridging science and policy, enhancing environmental justice, and achieving sustainable coastal and marine futures in Indonesia and comparable coastal nations.
