Abstract:
A single specimen of saltwater crocodile Crocodylus porosus Schneider, 1801 (1.50 cm in length) was captured and photographed by a local fisherman by gill net at fishpond around mangrove ecosystem of east coast Surabaya on December 2020. The location where the estuarine crocodile caught is an important wetland area in Surabaya with an excellent mangrove cover. Wonorejo mangrove location is about 10 km from the centre of Surabaya, the second-largest city in Indonesia. This finding is considered as a first reported of C. porosus in Surabaya, and at the same time is proof of the importance of the mangrove area on the east coast of Surabaya as a habitat for wildlife that must be conserved appropriately. Routine monitoring of mangrove areas, including their wildlife, is essential so that they are not displaced by the development of the city which changes the land function to become a residential area.

Abstract:
Utilisation of plant proteins to replace fish meal in shrimp feeds has become an important consideration because fish meal is becoming more expensive due to increasing demand worldwide. The potential use of palm kernel meal (PKM) in this study to substitute fish meal in the Pacific white shrimp (Litopenaeus vannamei) diets was evaluated by conducting a 90-day feeding trial. Shrimp juveniles with an initial average weight of 0.5 g, protein content of 10.74±0.70% were randomly distributed into five treatments in triplicates. Four isonitrogenous (approximately 35% protein) diets were formulated to contain 0% (D0), 25% (D25), 50% (D50) and 75% (D75) of PKM replacement and a commercial feed served as control treatment (Control). Results from this study revealed that shrimps fed D25 were comparable with those fed with Control as there was no significant difference (p>0.05) in weight gain and specific growth rate (SGR) between the groups. However, PKM inclusions above 50% showed detrimental effects on the growth performance. The highest total protein percent was observed in shrimp tissues fed with D25 (67.59±0.87%) and D75 showed the lowest protein among the treatments (57.4±0.63%) (p<0.05). Total lipid content was observed high in shrimps fed with Control (4.33±2.96%) and decreased with PKM replacement levels. The highest carbohydrate was found in shrimps fed with D75 (16.75±0.04%) and the lowest was found in shrimps fed with D25 (14.67±0.07%). When PKM is utilised to replace FM, a limit of 25% level should be recommended.

Abstract:
Muncar Beach, Banyuwangi Regency is an area with high disaster risk. Community-based disaster management will be much more effective than formal agencies set up by the state. But it also does not mean that formal institutions are not important. Education, counseling, and public awareness are non-structural/non-physical disaster mitigation activities. This study aims to analyze the level of knowledge and preparedness of coastal communities in Muncar, Banyuwangi Regency in dealing with disasters, and to find out how the community-based disaster mitigation system in Muncar Beach, Banyuwangi Regency is. This research uses qualitative methods with qualitative descriptive research. Data were obtained through observation, in-depth interviews, and documents. The subjects of this research are community leaders, fishermen, and the people of Kedungrejo Muncar Village. The analysis technique in this research is inductive. In this study, the inductive analysis used is an interactive analysis technique. The results show that the paradigm of disaster management at the population level has not changed much and is still associated with myths. Knowledge and awareness of coastal communities about disaster mitigation are still very low.Keywords: Mitigation, Disaster, Muncar, Banyuwangi

Abstract:
Mangrove, a unique ecosystem commonly situated on the coast, has a very vital role for the living creatures both inhabiting in and around the ecosystem. As the biggest mangrove forest holder in the world, Indonesia owns its great potential for both sustainable fisheries and community welfare. In order to preserve the mangrove ecosystem for sustainable fisheries, environmental improvement through mangrove rehabilitation program is important. WWF Indonesia collaborated with PT. Bogatama Marinusa (PT. Bomar) implement a mangrove rehabilitation program to support ASC (Aquaculture Stewardship Council) shrimp certification. The activity was implemented on 2019 at Binangasangka, Maros, South Sulawesi. The program was implemented in several steps namely planning, consolidation to communities, socialization and local support, seed preparation, planting, and monitoring and evaluation. The whole program has engaged multiple local environment-concern communities, especially youth community, and have collaborated significant local stakeholders namely the Institute of Brackish Aquaculture Research of Maros and the Technology University of Sulawesi, as well embraced local society. In the end, about 24 thousand mangrove seeds have been planted and covering up to 1 hectare. From the mentioned number, the successfully survived seeds have reached 74 % and hopefully well-settled in future. The overall activities were expected to contribute not only expanding mangrove coverage in coastal area, but also being the educational tools about environmental awareness to young generation.Keywords: mangrove, rehabilitation, community, Maros.

Abstract:
The plantation sector is a sector that plays a role in the country's foreign exchange earnings. One of the foreign exchange-producing plantation commodities is coffee. In 2011, foreign exchange earnings from coffee commodities resulted in an export value of US$ 1,085.89 million or 10.1% of the export value of all agricultural commodities, or 0.5% of non-oil and gas exports or 0.4% of the total export value. To increase coffee productivity both in quality and quantity, it is necessary to improve the economic environment and also have the entrepreneurial competence of coffee farmers. The purpose of this study was to analyze the influence of the economic environment and entrepreneurship on-farm performance. This research was carried out in Banyuwangi Regency which was carried out purposively with the research population being coffee farmers who had a coffee area of 0.5 - 1 Ha. The results of the study show that the economic environment has a positive effect on entrepreneurship as a result, the better the economic environment, the better the entrepreneurship of farmers. The economic environment does not directly affect the performance of coffee farming but has a direct effect on farmer entrepreneurship. Entrepreneurship has a positive effect on farm performance, as a result, the better the farmer's entrepreneurship, the better his farming performance.Keywords: Economic Environmental Factors, Entrepreneurship, Farming Performance, Coffee

Abstract:
The coastal area of Jangkar Village, Jangkar District is a transitional area between sea and land. The development of the coastal area of Jangkar Village often comes under pressure from various human activities and phenomena that occur on land and sea. This is illustrated in Jangkar Village, Jangkar District. Jangkar Village has a unique geographic location compared to other beaches, especially with the presence of a port that connects the waterway to Madura Island and fish auction sites, as well as cheap culinary stalls that attract tourists to visit. The economic condition of the people in Jangkar Village is currently experiencing almost no change due to the behavior of the people who only depend on sea products for their livelihoods. The purpose of this research is to examine the behavior of coastal communities that has an impact on the social and economic aspects of the community. This research uses a qualitative descriptive method that is carried out with a sociological approach, or in public administration research it is commonly called applied normative / empirical normative. The sample selection was carried out by purposive sampling with government informants and fishermen groups. The results showed that the behavior of coastal communities has an effect on economic conditions. This is also influenced by the low level of community education about the coastal area of Jangkar Village. The government should be able to work together with the community to improve the quality of education in the fishing village of Jangkar Village so that it has a positive impact on the economy of the people in the Jangkar village area.Keyword : Community Economy, Coastal Society, Behavior.

Abstract:
Eel (Anguilla sp.) is one of the important commercial fish in some countries particularly in East Asian countries such as Japan, South Korea, China, and Taiwan. The need of eel fry or frequently called as glass eel still relies on the natural capture. The issue of natural captured fish is the high level of bacterial infections and diseases. The dependence of glass eel from the nature provides an indication of infections of parasites and bacteria in glass eel. The existence of parasites and bacteria as microorganisms which are potential as pathogenic agents in the cycle of eel culture can be a serious obstacle, so that the glass eel handling needs a particular attention since the capturing proses from the nature. Therefore, identification of parasites and bacteria in the capture location of glass eel was necessarily conducted in Pelabuhan Ratu Bay, Sukabumi, West Java. The glass eel sampling was conducted in May-June 2019, in 3 locations of estuary with the highest capture yield namely Cimandiri River, Cikaso River and Cibuni River. The number of samples taken were 30 eels at each river location with 2 replicates, so that the total eel samples which were taken were 180 eels. Identification of parasites was conducted by examination of ectoparasite and endoparasite and dentification of bacteria was conducted by conventional method (biochemical method). Based on the result of identification, there was no parasite found in the glass eel samples, while bacteria found as many as 12 species and 3 dominant species namely Listeria sp. found in 40 eel samples with prevalence of 22.2%, Aeromonas hydrophila found in 28 eel samples with prevalence of 15.6%, and Staphylococcus spp. found in 22 eel samples with prevalence of 12.2%.

Abstract:
The utilization of fishery and marine resources in the form of fishing business in Banyuwangi Regency is still dominated by small-scale fisheries (traditional/small scale fisheries). It is known that there are still many fishing workers who depend on the fishermen for their livelihoods. So it is necessary to find alternative sources of additional income for small fishing households. The purpose of this study was to determine the economic behavior of fishermen's households, to analyze the contribution of off fishing businesses to the improvement of the fishermen's household economy, and to formulate alternative strategies to increase the income of fishermen's households in Banyuwangi Regency through off fishing employment. The research is focused on 2 sub-districts, namely Muncar District and Purwoharjo District, Banyuwangi Regency. The location selection was carried out by conducting a case study on small-scale fishing households that carried out an off-fishing business at the research location and 30% was taken using Simple Random Sampling. The analysis of the economic behavior of small fishermen households is described in the estimation of several variables of fishing experience, fishing frequency, number of fishing gear, boat size, and the addition of the amount of gasoline. The contribution of off-fishing businesses to the total household income of small-scale fishermen is quite varied, depending on the fishermen's income from fishing at sea. The greater the income of fishermen from catching fish in the sea, the greater the income of fishermen from catching fish at sea. By using the off fishing system, the strategy needed is the provision of technical training, especially regarding various fishery product processing to increase added value, institutional strengthening is carried out by making institutional reforms, and the problem of limited capital can be overcome by providing capital assistance.Keywords: economic behavior, income, strategy, off fishing

Abstract:
Indonesia has enormous potential in the field of fisheries, this is because about 70% of its territory is oceans and archipelagic countries. Shrimp farming in Indonesia is a practice that is widely practiced by Indonesians. This is because shrimp is a fishery commodity that has the highest demand. Aquaculture Base Group (ABG) aims to manage communities, who were originally individuals in managing ponds to become groups, because it will make it easier to get support from the government and get more benefits than only individuals. The program is implemented using several methods, namely socializing the importance of cultivation using the ABG method, explaining the advantages of using the ABG method, forming cadres for coordination between extension agents and the community so that communication can be evenly distributed, and distribution for each pond and job desk. As well as the holding of monitoring and evaluation, whether to get more efficient results when using ABG or individual methods. The ABG method is more efficient than using the individual method, including fry and feed can be purchased at a lower price, fry can be done together so that supervision will be easier, management of water sources is more maintained, and biosecurity is easier, and the impact of management be the responsibility of groups not individuals. Conclusion: the use of ABG cultivation method is more efficient, get affordable prices when buying fry and feed, disease management that can be managed together, cheaper electricity, easier biosecurity and more maintained water management (Tandon and Waste Water Treatment Plant) .Keyword : Fishery, shrimp farming, group, sustainable

Abstract:
The most important coastal socio-cultural management is the economic management of fishermen. As an archipelagic country, most of its territory consists of oceans, Indonesian fishermen should have a prosperous level of economic life. However, there are still many fishermen who are classified as poor. To improve the socio-cultural elements of the fishing community in Indonesia, a high entrepreneurial ethos is needed. This relates to the management of marine fisheries business. Aspects of short and long term planning must be prepared in detail. Sustainable development is needed to foster better utilization of marine resources. Social conditions are also related to the activities of fishermen in a social organization. Cultural conditions are the use of methods and technologies that have been used for generations to catch fish. Marine aquaculture innovation, providing freedom in a responsible manner, and respecting the rights of everyone can be done to improve the welfare and socio-cultural management of the coast. Socio-cultural transformation will give direction to economic transformation. The effort needed is to increase the knowledge of fishermen. The surrounding companies should provide business opportunities for local communities. Government policies will determine the success of coastal socio-cultural management.Keywords: management, coastal, socio-cultural

Abstract:
Shrimp aquaculture wastewater after the end of the rearing period has a high total organic matter (TOM) content of up to 87.74 mg/L. If the wastewater is disposed of directly without any efforts to reduce or treatment, it will disturb public waters ecosystem because of the high organic matter. The aim of this study was to determine the rate of reduce of organic matter in pond aquaculture waste. The study was carried out in January 2021. Pond wastewater samples were taken from the Tambak at the end of the maintenance period (120 days of maintenance). The trademarks of the bacterial consortium are EM4, Bio HS, BIO Prisma, Starbio plus, BIO2000, and Biolet. The experimental research was arranged in a completely randomized design with 6 treatments and 4 replications. Each treatment was filled with 2 liters of wastewater plus 6 ml of a liquid bacterial consortium. As for the solid bacterial consortium, 1 gram/L was added. Measurements of total organic matter, temperature, pH, dissolved oxygen, salinity and carbon dioxide were carried out every 24 hours for 72 hours of observation. The results showed that during 72 hours of immersion the highest percent reduction in organic matter was in treatment E (BIO 2000) of 95% (87.74 mg/L to 4.11 mg/L). The lowest percentage decrease was in treatment D (Starbio plus) of 83.4% (87.74 mg/L to 14.54 mg/L). However, in general 6 types of bacterial consortium trademarks can degrade organic matter. The levels of temperature, pH, dissolved oxygen and salinity are in optimum conditions, while carbon dioxide exceeds the threshold caused by the high activity of overhauling organic matter by bacteria. The conclusion was obtained that the trademark of the bacterial consortium BIO2000 was the most effective in reducing organic matter for 72 hours.

The method used in this study is the GIS approach with spatial analysis techniques, namely the techniques used in analyzing spatial / spatial studies. Based on the results of the study, it was shown that H. nemurus in the Progo river were found in areas with sandy clay substrates at a depth of 2 m, namely in the Ngeluwar area. The distribution of H. nemurus in the Progo river tends to be evenly distributed, because the conditions of the Progo river habitat support the life of H. nemurus.Keywords: Hemibagrus nemurus, Geographical Information System, Progo River.

Abstract:
Infeksi parasit pada budidaya ikan dapat memicu terjadinya infeksi primer akibat penurunan imunitas ikan sehingga memudahkan mikroorganisme lain baik bakteri maupun virus untuk masuk ke dalam tubuh ikan. Penelitian ini bertujuan untuk mengetahui, menghitung prevalensi dan intensitas parasit yang ditemukan di tambak lele kelompok tani ikan "Mino Ngremboko" di Desa Grabag Kecamatan Grabag Kabupaten Purworejo. Penelitian ini menggunakan metode kerokan dengan menelaah insang, lendir dari kulit, sirip dan saluran pencernaan pada benda kaca yang kemudian diamati secara mikroskopis menggunakan mikroskop cahaya perbesaran 10-40x. Parasit yang ditemukan adalah ektoparasit yang terdiri dari 6 spesies; Trichodina sp., Tetrahymena sp., Gyrodactylus sp., Dinoflagelata, Epistylis sp., dan Dactylogyrus sp. Tidak ditemukan parasit dari kelompok endoparasit dan hematozoa. Prevalensi tertinggi adalah Dactylogyrus sp. dengan angka prevalensi 54% dan terendah adalah Dinoflagella dengan angka prevalensi 10%. Intensitas parasit tertinggi dan terendah adalah Epistylis sp. (18,0 ind./ ikan terinfeksi) dan Dactylogyrus sp. (2,8 ind./ ikan yang terinfeksi), masing-masing. Dapat disimpulkan bahwa tingkat infeksi parasit pada tambak kelompok pembudidaya ikan berada pada tingkat normal/biasa berdasarkan kriteria prevalensi William dan Bunkley. Kata kunci: Ikan lele, Identifikasi Parasit, Prevalensi, Intensitas, Mino Ngremboko.
