Peningkatan Ketahanan Pangan Rumah Tangga Perikanan Berbasis Pangan Lokal “Remis” (Corbicula Sp): Studi Kasus Kota Palembang
Get PDFMasyarakat yang tinggal di sepanjang aliran Sungai Musi Kota Palembang mengandalkan penangkapan ikan sebagai mata pencaharian utama namun masih menghadapi tingkat kemiskinan dan prevalensi stunting yang masih relatif tinggi masing-masing mencapai 10,48 persen (BPS, 2023) dan 14,3 persen (SSGI, 2023). Salah satu upaya untuk menurunkan prevalensi stunting adalah dengan meningkatkan konsumsi pangan yang merupakan sumber protein. Untuk mengatasi tantangan ini, salah satunya dapat dilakukan dengan cara penguatan ketahanan pangan melalui peningkatan konsumsi kerang remis sebagai sumber protein. Penelitian ini menggunakan tiga pendekatan, yaitu studi literatur, survei, dan wawancara mendalam. Data dikumpulkan melalui wawancara mendalam kepada 15 orang masyarakat Kampung Remis, Kelurahan 5 Ulu, Kota Palembang, Sumatera Selatan pada Desember 2022. Informan terdiri dari nelayan remis, penjual remis, dan masyarakat dipilih secara purposive sampling dengan mempertimbangkan faktor-faktor seperti umur, jenis kelamin, pekerjaan utama, dan tingkat pendidikan kemudian data dianalisis dengan pendekatan kualitatif dan disajikan secara deskriptif. Remis sebagai sumber protein rumah tangga perikanan memiliki beberapa keuntungan yaitu ketersediaan mudah, potensi pengembangan budi daya remis dalam skala yang lebih besar secara komersial dan ramah lingkungan, dan Remis memiliki kemampuan adaptasi yang baik Beberapa tantangan sosial, ekonomi dan kebijakan yang ditemui yaitu pengetahuan dan kesadaran masyarakat, harga dan ketersediaan, regulasi dan kebijakan pemantauan kualitas dan keamanan pangan. Mengatasi tantangan ini akan memerlukan kolaborasi antara pemerintah, masyarakat, sektor swasta, dan pemangku kepentingan terkait.Tittle: Improving Household Food Security Based on Local Food “Clams” (Corbicula Sp): A Case Study in Palembang CityPopulations residing along the Musi River in Palembang City rely on fisheries as their primary source of income, but still face relatively high rates of poverty and stunting prevalence, reaching 10.48% (BPS, 2023) and 14.3% (SSGI, 2023), respectively. An effort to reduce the prevalence of stunting is possibly accomplished through increasing the consumption of protein-rich diets. To surmount this difficulty, food sustainability can be improved by increasing the consumption of shellfish as a source of protein. The study employs three methods: literature reviews, surveys, and in-depth interviews. The data was collected through in-depth interviews with 15 people from Kampung Remis, Kelurahan 5 Ulu, Palembang City, South Sumatra, in December 2022. The informants consisted of fishermen, vendors, and members of the community who were purposefully sampled based on age, gender, primary occupation, and level of education; the data was then qualitatively analysed and presented descriptively. Remis as a source of protein for household fishing has several advantages, including simple availability, commercially viable and environmentally friendly cultivation development potential, and high adaptability. Some social, economic, and policy challenges are knowledge and public awareness, price and accessibility, regulations and policies monitoring quality, and food security. Overcoming these challenges will require collaboration between governments, the public, the private sector, and related stakeholders
CHARACTERIZATION OF SPORE-FORMING BACTERIA ISOLATED FROM TILAPIA (OREOCHROMIS NILOTICUS) AND THEIR POTENTIAL FOR A PROBIOTIC CANDIDATE
Get PDFGram-positive spore bacteria are widely used as probiotics in general sectors. However, there are still limited bacterial isolates as probiotic candidates available from indigenous isolates, especially in aquaculture. This study aimed to obtain potential spore-forming isolates as probiotic candidate for tilapia. Tilapia fish samples were collected from Sukabumi, Ciamis, Serang, and Papua. Bacterial isolates were isolated from the digestive tract of tilapia. Bacteria were identified based on their morphological, molecular characteristics, complete genome composition, and cell surface identification based on hydrophobic properties. In this study, six bacteria were isolated and identified by molecular characteristics using 16S rRNA sequences. Based on the phylogenetic analysis, the 9 PP isolate was Priestia megaterium basonym: Bacillus megaterium, CMS 16N isolate was Brevibacillus halotolerans, PPN 10 isolate was Bacillus sp., 3.1 SKBM isolate was Bacillus mycoides, CMS 22 N and SRG32 isolate were Bacillus subtilis. Six bacteria had different phenotypicals, ATGC sequence compositions, and a higher proportion of total G~C sequence composition above 50%. The coherent cell surface hydrophobicity test was positive on the SAT, SA, AA, and compact growth patterns in soft-agar media for 9 PP, CMS 22 N, and SRG32 isolates. From our study, the indigenous spore-forming bacteria isolated from tilapia stomachs are enzymatic bacteria, which have a strong attachment to host tissue and high potential as a probiotic candidate for fish. Various hydrophobicity test results from each isolate indicate that the protein composition in the cell surface is different

Pengaruh Kerapatan Mangrove terhadap Kelimpahan Kepiting Mangrove (Scylla Spp.) di Kawasan Ekosistem Mangrove Rembang
Get PDFKepiting mangrove merupakan salah satu komoditas perikanan asal Indonesia yang banyak diekspor keluar negeri. Salah satu daerah yang menghasilkan kepiting mangrove adalah Kabupaten Rembang. Penelitian ini akan menganalisis pengaruh kerapatan mangrove terhadap kelimpahan kepiting mangrove pada ekosistem mangrove di Kkabupaten Rembang. Penelitian dilakukan pada 3 (tiga) stasiun yang berlokasi di pantai desa Pasar Banggi Kabupaten Rembang. Metode penelitian ini menggunakan sistem jalur transek kuadrat pada setiap stasiun. Data kerapatan mangrove didapat berdasarkan banyaknya individu setiap meter perseginya. Sedangkan untuk kelimpahan kepiting mangrove sampel diambil sebanyak 4 (empat) kali dan dihitung banyaknya kepiting mangrove per meter perseginya. Hasil data tersebut dianalisis dengan menggunakan regresi linear SPSS. Hasil analisis menunjukkan bahwa kawasan ekosistem mangrove di desa Pasar Banggi Kabupaten Rembang memiliki kepadatan jenis spesies mangrove yang sangat padat. Spesies mangrove yang dominan adalah Rhizophora mucronata, Rhizophora apiculata,dan Avicennia marina. Kelimpahan kepiting mangrove yang paling tinggi adalah Scylla tranquebarica yang ditemukan pada semua stasiun. Pada penelitian ini, kerapatan mangrove tidak mempengaruhi kelimpahan kepiting mangrove. Terdapat dua stasiun yang memiliki nilai kerapatan jenis mangrovenya sama namun jumlah kelimpahan kepitingnya lebih rendah dari pada yang lain. Hal ini kemungkinan disebabkan pada stasiun yang kelimpahan kepitingnya rendah jenis spesies mangrove terbanyak adalah spesies Avicennia marina yang memiliki akar ceker ayam sehingga tidak dapat menjadi kanopi yang baik bagi ekosistem kepiting didalam stasiun tersebut. Untuk meningkatkan kelimpahan kepiting di Kabupaten Rembang lebih baik menanam mangrove dengan genus Rhizophora
IMPROVING PROFITABILITY OF INTEGRATED RICE-SHRIMP FARMING IN BRACKISH AREA: A CASE STUDY OF MEKONG DELTA, VIETNAM
Get PDFRotation between rice and shrimp farming by way of filter ponds and diversification of farm activities was studied with the aims of testing the efficiency of filter ponds and evaluating the combination of incorporating the growing of upland-crops on dikes of rice fields. Three groups of farmers participated in study trials which were the pilot group used a filter pond and applied new methods, the control group had a filter pond and applied the recommended new methods, and the normal practice (control) group not having a filter pond. Results showed that the rice-shrimp farming system using a filter pond improved water quality (pH, alkalinity and salinity) and reduced input costs. Growing upland crops on the dikes had a high financial return; though for both vegetables and the grass for the dairy cows will strongly depend on the market. On one hectare of land, farmers using a filter pond for rice-shrimp farming combined with upland-crops had a higher economic return than the traditional rice-shrimp farming system (2,812 compared with 854 USD/ha/year). However, implementing this model requires farmers to build filter ponds to aid freshwater storage, proper management skills and family labour resources. Diversification of farm activities such as integrated rice-shrimp culture may be a strategy for farmers for adapting to the impacts of climate change such as extreme weather events, less rain and saltwater intrusion

Get PDFKondisi wilayah pesisir yang kaya potensi ternyata tidak berbanding lurus dengan tingkat kesejahteraan masyarakat di wilayah pesisir, hal tersebut juga terjadi di Provinsi Daerah Istimewa Yogyakarta (DIY). Kegiatan pariwisata merupakan salah satu solusi untuk meningkatkan kesejahteraan masyarakat, namun disisi lain perkembangan kegiatan pariwisata baharí di wilayah pesisir DIY masih menghadapi berbagai permasalahan lingkungan. Salah satu konsep yang dapat diterapkan untuk mengatasi permasalahan di wilayah pesisir adalah ekonomi biru atau Blue Economy (BE), yaitu pemanfaatan sumber daya laut secara berkelanjutan untuk meningkatkan kesejahteraan masyarakat dengan mengoptimalkan pariwisata yang berkelanjutan. Tujuan penelitian ini adalah untuk menganalisis potensi penerapan BE dan strategi pengembangan pariwisata berkelanjutan di wilayah pesisir DIY. Penelitian ini dilaksanakan dalam kurun waktu 5 bulan, mulai bulan Januari sampai dengan Mei 2023. Pengumpulan data menggunakan literature review dan wawancara dengan Dinas Kelautan dan Perikanan, Bappeda dan Dinas Pariwisata DIY. Data kemudian dianalisis dengan menggunakan indikator penerapan BE yang merupakan kombinasi Indeks Kesehatan Laut Indonesia (IKLI) dan Ocean Health Index (OHI). Strategi pengembangan dianalisis menggunakan matriks Strengths, Weaknesses, Opportunities dan Threats (SWOT). Hasil analisis menunjukkan potensi penerapan ekonomi biru dalam mendukung pariwisata berkelanjutan di DIY sangat besar, namun masih dibutuhkan beberapa strategi pengembangan. Title: The Potential Apllication of Blue Economy in Supporting Sustainable Tourism in The Coastal Areas of Yogyakarta ProvinceThe condition of coastal areas that are rich in potential is not directly proportional to the level of welfare of the people in coastal areas, and this also happens in the Yogyakarta Province (DIY). Tourism activities are one of the solutions to improve people’s welfare. However, on the other hand, developing marine tourism activities in the DIY coastal area still faces various environmental problems. One concept that can be applied to address problems in coastal areas is the blue economy or Blue Economy (BE), namely the sustainable use of marine resources to improve people’s welfare by optimizing sustainable tourism. This study analyzed the potential for applying BE and strategies for developing sustainable tourism in the DIY coastal area. This research was carried out over five months, from January to May 2023. Data collection used literature reviews and interviews with the Maritime Affairs and Fisheries Service, Bappeda and the DIY Tourism Office. The data is then analyzed using BE implementation indicators. The development strategy is analyzed using the Strengths, Weaknesses, Opportunities and Threats (SWOT) matrix. The analysis results show that the potential for implementing the blue economy in supporting sustainable tourism in DIY is excellent, but several development strategies are still needed
Prototype Testing of Automatic Vessel Tracking System using Web-Based Visualization
Get PDFAutomatic Tracking System is an example in the development of navigation technology that is needed in every means of transportation by land, water, or air. An example of its application in the field of fisheries management is the Vessel Monitoring System (VMS). The purpose of this study was to develop a telemetry technique particularly automatic vessel tracking system. In this study is expected to produce a prototype which can provide information about the movement of traditional fishing boats, especially in coastal areas. Prototype testing in this study was limited to the performance of a prototype based on the capability of the electronics and the resulting output data. Output data obtained by two methods: (1) the trial was stationary, and (2) mobile test. This study also examined the comparison between tracker prototype with GPS handheld. Mobile tracker marks the position automatically whenever the tool is turned on. The increasing distance between the transmitter unit to the receiver unit, the deviation would be even greater. This tool was sensitive in responding and quickly perform the recording every movement. When compared to handheld GPS, this tool has good accuracy and precision indicated by a 95% confidence interval
