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

Guppy fish is currently in high demand because they has interesting color variations such as red, blue, yellow. The carotenoid content in red peppers and red spinach is able to increase the brightness of the color of the fish. This research aims to find out the effect of the addition of red peppers and red spinach on guppy fish color. Completely Randomized Design with 3 treatment and 3 repetitions was used. The research data was analyzed by using the Adope Photoshop app by observing the discoloration that occurred before and after the treatment by using color libraries. The study found that the percentage of blue and purple in guppy fish increased. This was related to the absence of carotene that associated with protein and produces carotenoproteins. The most prominent discoloration result was the treatment 1 (addition of peppers). In treatment 1 there was a significant discoloration of the blue color with the code 732-0 from 0% to 11.9%, while in the treatment 2 (addition of spinach) color coded 732-0 was changed from 0% to 5.88%, the treatment 3(control) treatment was changed from 1.21 % to 0.6%. Meanwhile, the purple color with the code 728-0 on treatment 1 from 0% to 2.36%, on treatment 2 from 0% to 0.22% and on treatment 3 purple color did not came out. It can be concluded that the most influential to the color of guppy fish was peppers, spinach and control treatment, respectively.Keywords : red spinach, carotene, guppy fish, red peppers, color.

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

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

Daun pepaya merupakan bahan alami yang sering dimanfaatkan dibidang perikanan air tawar khususnya sebagai pakan tambahan, karena memiliki kandungan enzim yang dibutuhkan oleh ikan. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan serbuk daun pepaya pada pakan untuk meningkatkan pertumbuhan ikan lele (Clarias sp). Pakan yang digunakan pada penelitian ini yaitu pakan komersil dengan kandungan protein 30% yang ditambahkan serbuk daun pepaya. Serbuk daun pepaya didapatkan dari daun pepaya yang dikeringkan terlebih dahulu sampai benar-benar kering. Setelah kering daun pepaya dihaluskan dengan menggunakan blender. Penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap (RAL), dengan 4 perlakuan dan 3 ulangan. Perlakuan 1 (P1) sebagai kontrol (tanpa pemberian serbuk daun pepaya), P2 (pakan dengan serbuk daun pepaya 2 %), P3 (Pakan dengan serbuk daun pepaya 3,5 %), P4 (pakan dengan serbuk daun pepaya 4,2 %). Parameter pertumbuhan merupakan parameter utama yang diamati pada penelitian ini. Analisis data menggunakan ANOVA untuk meliihat perbedaan pengaruh dari masing masing perlakuan dengan selang kepercayaan 95% (p>0.05). Hasil penelitian menunjukan bahwa penambahan serbuk daun pepaya memberikan pengaruh nyata terhadap laju pertumbuhan panjang dan berat (p>0.05), dimana perlakuan terbaik terdapat pada P3 dengan pertumbuahan panjang sebesar 2,69 g dan 3,51 cm, berat dan panjang spesifik 3,89 g dan 5,89 cm, serta FCR 0,517.Kata kunci: pertumbuhan, serbuk, daun papaya
