Bluru Kidul Village is an area located near the northeastern coast of Sidoarjo, where its geographical position provides significant benefits for the community. Consequently, the majority of residents work as fishermen and live side by side with the marine ecosystem. Due to the existence of Bluru Kidul Village, Sidoarjo City is often referred to as a fisheries or coastal city. The fish resources in these waters are dominated by small pelagic fish, large pelagic fish, and demersal fish. One of the most widely used fishing gears is the gill net. This study applied treatments with soaking durations of 2 hours, 3 hours, and 4 hours. The objectives of this research were to identify the composition of gill net catches, analyze the effect of different soaking times on gill net catches, and determine the optimal soaking duration for catching Indian mackerel (Rastrelliger) using gill nets. Data analysis was conducted using statistical methods, including analysis of variance (ANOVA) and normality tests to ensure data suitability. To determine whether soaking duration had a significant effect, a further statistical test, namely the Least Significant Difference (LSD) test, was applied to identify which soaking time produced the best catch of Indian mackerel. The results indicated that there were significant differences in catch variables between the 4-hour treatment and the 3-hour and 2-hour treatments, whereas the difference between the 3-hour and 2-hour treatments was not significant. This finding demonstrates that the 4-hour soaking duration resulted in significantly different catch outcomes compared to the 3-hour and 2-hour durations, but no significant difference was observed between the 3-hour and 2-hour treatments.

This study aims to analyze the effect of fishing ground differences between WPPNRI 711 and 712 on squid (Loligo spp) catches using boat-operated falling nets landed at Nusantara Fishing Port Muara Angke, Jakarta. The research employed a quantitative approach with a two-treatment experimental design, involving fishing operations in two different areas with an equal number of trips (six trips each), analyzed using an independent samples t-test. The results indicated no statistically significant difference in catches between WPPNRI 711 and 712 (p = 0.747 > 0.05). However, production data revealed variations in catch differences, with CPUE (Catch Per Unit Effort) in WPP 711 being higher than in WPP 712. These variations are likely influenced by environmental factors, oceanographic conditions, fishing pressure, and squid spawning seasons. The implications of this study highlight that differences in fishing grounds do not always produce significant statistical impacts on catches but remain crucial for sustainable squid fisheries management. Policy recommendations include regulating fishing efforts based on spawning seasons, routine stock monitoring through CPUE, and adopting advanced fishing technologies to enhance efficiency and sustainability. This research provides valuable input for fisheries management and supports sustainable utilization of squid resources at Muara Angke.

Capture fisheries are an important economic sector in the coastal area of ​​Depok Beach, Yogyakarta Special Region. Fishing activities in this area use various fishing gear, one of which is the bottom gill net. However, the use of this fishing gear can have negative impacts on the aquatic environment and marine ecosystem, such as the decline in the population of white pomfret and ribbonhead fish, which are the main catch. This study aims to analyze the level of environmental friendliness of the use of bottom gill nets in Depok Beach using a descriptive quantitative approach. The methods used in this study include direct surveys of fishermen, observation of fishing operations, and analysis of catch results. Data were collected through a questionnaire containing 9 indicators compiled by the FAO, which cover aspects of gear selectivity, impact on aquatic habitats, fisherman safety, catch quality, and social acceptance of the fishing gear. The results showed that bottom gill nets had the lowest level of selectivity with a score of 1.13, indicating that this tool is less selective in selecting the types of fish caught. However, the indicator regarding consumer safety received the highest score of 4.00. Overall, the test results show that the use of bottom gill nets at Depok Beach has an environmental friendliness score of 27.06, which indicates that this fishing gear is classified as environmentally friendly even though it needs improvement in terms of selectivity.

Capture fisheries are one of the most contributing sectors in producing fishery products.The fourfinger threadfin (Eleutheronema tetradactylum) is one of the key commodities in the capture fisheries sector of Pasuruan City. The catch yield of this species is influenced by the mesh size of the gillnet used. This study aimed to determine the effect of different mesh sizes on the catch yield of fourfinger threadfin and to identify the most effective mesh size. The research was conducted using an experimental fishing method with a Randomized Block Design (RBD) comprising three gillnet mesh size treatments: 1.75 inches, 2.5 inches, and 4 inches, with nine fishing trips. Data on catch weight and number were analyzed using a One-Way ANOVA followed by the Least Significant Difference (LSD) test. The ANOVA results showed an F-value of 10.083 with a significance level of 0.001 (p-value < 0.05), indicating a significant difference in the catch weight of fourfinger threadfin (Eleutheronema tetradactylum) among the mesh size treatments. This finding suggests that mesh size has a significant effect on catch weight, with the 2.5-inch mesh size being the most effective for catching fourfinger threadfin in the Madura Strait, as it produced the optimal catch weight compared to 1.75-inch and 4-inch mesh sizes.

Panggungrejo District in Pasuruan City is a central hub for fishing activities with significant potential for capture fisheries production. One of the fishing gears used by fishermen in this area is the boat dredge, which is classified as an active fishing gear. This study aims to assess the environmental friendliness of the boat dredge used by fishermen in Panggungrejo based on the principles of the Code of Conduct for Responsible Fisheries (CCRF). The research employs a descriptive method, using data collection techniques such as interviews with structured questionnaires, direct observations, document analysis, and literature review. The study involved 32 respondents consisting of fishermen using the boat dredge. Data analysis was performed by assigning scores based on the principles outlined in the CCRF that are related to sustainability and environmental impact of the fishing gear. The results showed that the boat dredge in Panggungrejo scored a total of 855, with an environmental friendliness score of 26.71. Based on this score, the boat dredge falls into category III, considered “environmentally friendly.” However, several indicators related to resource efficiency and the impact on aquatic ecosystems still need improvement to further enhance the environmental friendliness of this fishing gear. This study provides recommendations for the development and improvement of more environmentally friendly fishing techniques and increasing fishermen’s awareness of sustainability in fisheries practices.

This study aims to analyze the effect of communication and work environment on employee morale at the Maritime Affairs and Fisheries Service of Bima Regency. A quantitative approach was employed using a Likert-scale questionnaire distributed to 80 respondents selected through purposive sampling. Data were analyzed using multiple linear regression with SPSS for Windows. The results reveal that communication (β = 0.551; t = 18.459; p < 0.05) and work environment (β = 0.401; t = 16.786; p < 0.05) have a significant partial effect on employee morale. Simultaneously, these two variables contribute 94.4% to the increase in employee morale (R² = 0.944; F = 43.288; p < 0.05). These findings indicate that effective communication and a supportive work environment can enhance motivation and productivity among public sector employees. The practical implication of this study suggests that organizational management needs to improve the quality of internal communication and create a conducive work environment to optimize organizational performance.

This study analyzes the potential use of cockle shell waste and coal fly ash as alternative raw materials in the production of composite brake pads. The high volume of industrial and fisheries waste, which has not been optimally utilized, encourages the exploration of environmentally friendly materials with adequate mechanical performance. The main focus of this research is the compressive strength of the produced brake pads, as this parameter is crucial for ensuring effective and safe braking performance. The method used includes the mixing and molding of composite materials with varying compositions of cockle shell and fly ash, followed by compressive strength testing according to standards. This study also takes into account the environmental impact of using waste as filler material, which is expected to reduce reliance on conventional materials and decrease waste that contaminates the environment. The results of the study are expected to provide empirical data on the potential of these two wastes as fillers in brake pad matrices and to identify the optimal formulation that provides the highest compressive strength. This study contributes to the development of sustainable braking materials and efforts to mitigate the environmental impact of waste, while also opening opportunities for the reuse of waste that has previously been poorly managed.

Limited knowledge and utilization of digital technology in the fisheries and plantation sectors remains a major obstacle for the people of Samo Village, South Halmahera Regency, the majority of whom work as fishermen and farmers.

This study aims to analyze the authority structure between the Ministry of Maritime Affairs and Fisheries (KKP) and Regional Governments in managing coastal areas through marine spatial utilization following the enactment of Law Number 6 of 2023 concerning the Stipulation of Government Regulation in Lieu of Law Number 2 of 2022 concerning Job Creation into Law. The main instrument studied is the Confirmation of Conformity of Marine Spatial Utilization Activities (KKPRL), which functions as a licensing instrument and a control mechanism to ensure that marine spatial utilization activities remain directed, integrated, and aligned with the principles of ecological, social, and economic sustainability. The research approach used is a juridical-empirical approach with a qualitative descriptive analysis method. Through this approach, the research not only examines legal norms but also captures the practice of implementing authority in the field. The results show that although the Job Creation Law is oriented towards simplifying business licensing, several problems remain that have implications for the effectiveness of coastal governance. These issues include disharmony between central and regional regulations, overlapping authority between the Ministry of Marine Affairs and Fisheries (KKPRL) and regional governments, and weak synchronization between national policies and regional instruments such as the Coastal and Small Islands Zoning Plan (RZWP3K). In addition to regulatory constraints, this study also highlights institutional and technical aspects. Limited human resource capacity in the regions, a lack of understanding of KKPRL procedures, and minimal inter-agency coordination hamper the effectiveness of coastal management. These conditions result in slow investment realization, conflicts over spatial use, and potential coastal environmental degradation. Therefore, this study recommends a strategy for harmonizing authority through improving vertical-horizontal coordination, strengthening the institutional capacity of regional governments, and developing derivative regulations consistent with the principles of good governance.

Plankton are microorganisms that have an important role in aquatic ecosystems, especially in fisheries cultivation activities. The presence of plankton functions as natural feed for aquatic organisms, thus affecting the growth and survival of aquaculture biota. However, in the rainy season the quality of pond water often changes, especially in pH parameters, which can disrupt the stability of aquatic ecosystems. One of the efforts made to maintain pH stability is with periodic liming techniques. This study aims to determine the biodiversity of plankton in the Bossbaster cultivation pond by applying periodic calcification techniques. The research was carried out on October 10–23, 2022 at the Bossbaster cultivation pond. The study focuses on aspects of abundance, diversity, uniformity, and dominance of plankton, both phytoplankton and zooplankton. The results showed that the average phytoplankton abundance in pond 1 was 41,002 cells/L, pond 2 was 40,853 cells/L, and pond 3 was 32,826 cells/L. Meanwhile, the average zooplankton abundance in pond 1 was 51 ind/L, pond 2 was 52 ind/L, and pond 3 was 66 ind/L. The average value of the phytoplankton diversity index ranged from 0.809–0.930,  Meanwhile, zooplankton ranges from 1.1863–1.4740. The phytoplankton uniformity index ranges from 0.4458–0.4814, while zooplankton reaches 0.880–0.881. The phytoplankton dominance index is in the range of 0.479–0.4809, and zooplankton is in the range of 0.2645–0.3514. These findings show that periodic liming techniques are able to maintain the stability of pond conditions so as to support the sustainability of plankton as an indicator of water quality. Thus, the application of this technique can be an important strategy in supporting the sustainability of aquaculture while improving the efficiency of pond management in a sustainable, innovative, and adaptive manner to changes in the increasingly complex aquatic environment.

Pesantren, as an Islamic educational institution that has long been a center of religious learning and character development, has great potential in advancing entrepreneurship based on local wisdom. The role of pesantren is not only limited to teaching religious studies, but also includes coaching students to have economic independence and competitiveness in the midst of the Times. Local wisdom that grows around pesantren can be an important capital in developing businesses that are relevant to the needs of the community. However, optimizing the function of pesantren in producing students who are independent and able to compete still faces various challenges. One of the main obstacles is the development of Human Resources (HR) which is not only oriented to mastering the theory, but also on practical skills and understanding of local values. Without the right strategy, such great potential is difficult to realize sustainably. This study aims to explore strategies that can be applied in the development of human resources in order to improve the performance of local wisdom-based entrepreneurship in the boarding school. The research method used is a qualitative approach with case studies on several boarding schools that have succeeded in forming productive business units by utilizing local potential, such as agriculture, fisheries, crafts, and food product processing. Research findings indicate that several crucial factors in building entrepreneurial human resources in pesantren include: strengthening character and work ethic, hands-on practice-based training in the field, collaboration with local business actors for knowledge transfer and market networking, as well as historical and philosophical understanding of local wisdom values. The success of entrepreneurship development in pesantren depends on the integration of spiritual aspects, practical skills, and knowledge about the potential of the region. Based on the results of the study, an integrated entrepreneurship training model that combines science, faith, and concrete action is recommended. This Model is expected to produce great pesantren entrepreneurs, competitive, and able to adapt and face global challenges without leaving their identity and noble values.

The fisheries sector plays a strategic role in Indonesia's national economic development due to its significant contribution to meeting food needs, creating jobs, and earning foreign exchange. However, this sector still faces various serious challenges, such as Illegal, Unreported, and Unregulated (IUU) Fishing practices, excessive exploitation of marine resources, degradation of aquatic ecosystems, and weak compliance with applicable legal provisions. These problems not only impact the sustainability of fisheries resources but also threaten the economic sustainability of coastal communities. This study aims to analyze the government's role in overseeing the fisheries sector in Indonesia, which includes regulatory and institutional aspects, and the implementation of supervision in the field. The research method used is a normative juridical approach through a review of relevant laws and regulations, including Law Number 31 of 2004 concerning Fisheries as amended by Law Number 45 of 2009, and other derivative regulations. The analysis also considers the role of supervisory institutions such as the Ministry of Maritime Affairs and Fisheries (KKP), the Indonesian Navy (TNI AL), and law enforcement officials in preventing and prosecuting violations in this sector. The research findings indicate that the government plays a strategic role in establishing policies, establishing oversight institutions, providing monitoring facilities and infrastructure, and taking legal action against violators. However, oversight effectiveness is still suboptimal due to limited human resources, monitoring technology, inter-agency coordination, and low legal awareness among fisheries business actors. Therefore, strengthening an integrated oversight system, increasing the capacity of officials, utilizing information and satellite technology, and consistent law enforcement are necessary. These steps are expected to ensure sustainable management of Indonesia's fisheries sector, protect marine resources, and support national economic growth.

Purse seine fishing gear is a type of fishing equipment consisting primarily of a large net, designed to catch both large and small pelagic fish. This study aimed to (1) determine the effect of time differences—morning and evening—on the catch of flying fish using mini purse seine fishing gear, and (2) identify the composition and dominant species caught in each fishing period. The research was conducted at Banda Neira Pier, Banda District, Central Maluku Regency, Maluku, Indonesia. An experimental fishing method was applied, and data were analyzed using the Two Sample t-Test. Fishing operations were carried out over 16 trips, equally distributed between morning and evening sessions. The total recorded catch comprised 15,078 kg of mackerel (Rastrelliger sp.), 4,017 kg of skipjack (Katsuwonus pelamis), 18,743 kg of deho (Euthynnus affinis), and 45,601 kg of flying fish (Decapterus sp.). In the morning, the total catch reached 36,005 kg, dominated by flying fish, whereas in the evening, it was 50,250 kg, also dominated by flying fish. Statistical analysis using the Two Sample t-Test focused on the dominant species, flying fish, and revealed a p-value of <0.05. This indicates a significant difference in the composition of the catch between morning and evening fishing activities. The findings suggest that fishing time plays a crucial role in catch volume, particularly for flying fish, with evening fishing showing higher yields. These results can be valuable for optimizing fishing strategies, improving efficiency, and supporting sustainable fisheries management in Banda Neira and similar pelagic fishing grounds.

The Batanghari River is a vital water source in Jambi Province, used by the community for various purposes, including domestic, agricultural, and fisheries needs. However, with increasing human activities, such as the discharge of household waste, industrial waste, and agricultural waste, the river's water quality is at risk of microbiological contamination that can endanger public health and the environment. This study aims to identify the presence of bacteria in the Batanghari River water, in order to assess the potential for biological contamination that can negatively impact public health and the surrounding ecosystem. The method used in this study included taking water samples from several locations along the river. After sampling, bacterial isolation and identification were carried out using Nutrient Agar (NA) media using the pour method. The results of the isolation process showed the growth of bacterial colonies that varied in shape, size, and color, indicating microbiological contamination, especially by heterotrophic bacteria. These findings indicate that the Batanghari River water contains microorganisms that reflect the potential for microbiological contamination. Therefore, this study emphasizes the importance of regular water quality monitoring and the need for sustainable management measures to maintain the health of the ecosystem and surrounding community. With routine monitoring, it is hoped that potential contamination that could be harmful to health can be detected early. Furthermore, the results of this study are expected to form the basis for better policy-making in water resource management and increase public awareness of the importance of maintaining water quality for sustainable life and environmental health. This study provides a preliminary overview of the microbiological condition of the Batanghari River water and emphasizes the need for greater attention in water resource management to prevent negative impacts on health and the environment.

This study aims to analyze in depth the structure of production cost components and determine a reasonable and competitive selling price for shrimp farming in the Venambak Shrimp Farm. The background of this study is the need to determine the cost efficiency and profit potential of shrimp farming activities, so that business actors can make the right decisions and be oriented towards sustainability. The study uses a quantitative descriptive approach with the full costing method to calculate the total production costs, and the cost plus pricing method to determine the selling price. The data used consists of primary data, such as details of operational expenses during one cultivation cycle (six months), as well as secondary data obtained from internal company reports and records. The results of the analysis show that the total production costs incurred in one shrimp cultivation cycle reached Rp16,085,208,000, with a total harvest of 1,000,000 kg. Based on these figures, the cost of goods manufactured (COGS) was obtained at Rp16,085 per kg. In determining the selling price, the company used the cost plus pricing method and set the selling price at Rp80,000 per kg. Thus, the profit margin obtained by the company reached Rp63,915 per kg. Gross profit generated during one cultivation cycle reached Rp63,915,000,000. If cultivation were conducted in two cycles per year, the annual gross profit could potentially increase to Rp127,830,000,000. These findings indicate that with efficient cost management and the right pricing strategy, shrimp farming has significant profit potential. Therefore, intensive and sustainable shrimp farming development at the Venambak Shrimp Farm is highly feasible to improve the competitiveness and welfare of fisheries business actors.

This study aims to explore and analyze the implementation of internal control mechanisms within Ministries/Agencies that received a disclaimer opinion on their audited financial statements. It also examines the form of financial transparency applied by these institutions in the preparation of their financial reports. The research focuses on the role of government internal audits in two institutions: the Ministry of Marine Affairs and Fisheries and the Indonesian Maritime Security Agency (BAKAMLA), utilizing a qualitative literature synthesis approach. The research method employs a descriptive qualitative design. Based on the findings, it is concluded that the lack of supervision by internal auditors and the Supreme Audit Agency (BPK) over these two institutions stems from several factors: limited competence and capacity of internal auditors, weak internal control systems and structures, lack of auditor independence, and inadequate routine monitoring and evaluation. Furthermore, in preparing financial reports, Ministries and Agencies are required to adopt financial transparency practices by preparing financial statements in accordance with Government Accounting Standards (SAP), disclosing complete notes to financial statements, and utilizing transparent and integrated financial applications.

Flying fish (Hirundichthys oxycephlus) roe filaments, which are often considered as by-products, have high protein content and various essential nutrients, thus potentially increasing the nutritional value of food products. With innovation and in-depth research, this waste can be transformed into products with economic value while supporting the implementation of sustainability principles in the fisheries industry, in this case sauce as a flavoring that has become an important part of the food industry. This study aims to determine the quality of the texture and taste of chili sauce fortified with fly fish (Hirundichthys oxycephlus) roe filament extract and to determine the protein content and water content of chili sauce enriched with fly fish (Hirundichthys oxycephlus) roe filament extract. The methodology used in this study was Complete Random Design (CRD) with variations in filament powder concentration (0%, 0.5%, 1%, and 1.5%) on the sensory characteristics of chili sauce, which include aroma, color, taste, and texture. The results of organoleptic tests showed that the addition of fly fish (Hirundichthys oxycephlus) egg filament extract had a significant positive impact on all sensory parameters tested. The average aroma score increased from 2.88 in the non-enriched treatment to 3.90 at the highest filament powder concentration (1.5%). In addition, the taste score also showed the most striking increase, from 2.80 to 4.33. Analysis of the water content of the chili sauce product was recorded at 79.93% according to (SNI 01-2976-2006), while the protein content reached 10.53%, indicating the potential of this product as an additional source of protein in daily consumption patterns.

Natuna waters are the most vulnerable area to illegal fishing because there is abundant potential for fishery resources. It was recorded that from May to December 2016, there were 280 foreign vessels in Natuna waters, which resulted in economic losses of 2.98 trillion Rupiah. This study aims to examine and assess the policies and actions that the Indonesian government has implemented in overcoming illegal fishing activities in the area. The results of this study are that the Natuna Waters Area is part of the Indonesian Archipelago Sea Lane (ALKI) and functions as a global waterway. The Natuna Waters Area borders with neighboring countries and is connected to open waters, making it vulnerable to illegal fishing activities. The Indonesian government's strategy in dealing with cases of unlawful fishing in Natuna waters effectively increases the protection of state sovereignty and marine resources through policies such as sinking ships and maritime diplomacy. However, this implementation policy overcomes obstacles in the form of intimidation from other countries, such as China, and weaknesses in supervision and coordination between domestic institutions, which can affect microorganisms in fisheries management and maritime security in the area.

Aceh’s economy has long been dominated by the oil and gas sector, particularly LNG Arun exports, which contributed more than 40% of regional GDP (GRDP) in the early observation period. However, declining production after 2014 drastically reduced its share to below 20%, and in recent years, to only around 10–12%. This study aims to analyze the contribution of oil and gas (migas) and non-oil and gas (nonmigas) exports to Aceh’s economy and to assess the potential of export diversification as a sustainable development strategy. The research employs a quantitative approach using secondary time series data from 2007–2021 obtained from BPS, Bank Indonesia, and other official sources. Data were analyzed descriptively and through simple econometric models, including OLS regression and cointegration tests. The findings reveal that oil and gas exports are significant in the short term but have weakened in the long term. In contrast, non-oil and gas exports, although relatively small, exhibit stable growth and demonstrate a long-term relationship with GRDP. These results underscore the importance of diversifying exports towards nonmigas commodities, particularly coffee, cocoa, rubber, and fisheries. The practical implication is the urgent need for Aceh’s development strategy to shift from oil and gas dependence towards globally competitive nonmigas industrialization
