Abstract

Pasar tradisional merupakan tempat masyarakat jual beli kebutuhan hidup diantaranya ikan laut. Ikan laut termasuk sumberdaya perikanan yang memiliki nilai ekonomis penting yang diidentifikasi berdasarkan penggolongannya yaitu ikan pelagis dan ikan demersal. Identifikasi jenis ikan tingkat spesies penting dilakukan untuk penentuan status konservasi dan komposisi jenis ikan. Penelitian ini bertujuan untuk menganalisis komposisi jenis ikan dan status konservasi jenis ikan laut yang diperdagangkan di pasar tradisional Kota Pangkalpinang. Penelitian ini dilaksanakan pada bulan Oktober 2023 di empat pasar tradisional Kota Pangkalpinang. Metode penelitian menggunakan metode survei dengan wawancara ke pedagang dan observasi di empat pasar tradisional di Kota Pangkalpinang. Jenis ikan laut yang diperdagangkan di empat Pasar Tradisional Kota Pangkalpinang teridentifikasi sebanyak 30 famili dan 55 spesies ikan laut yang terdiri dari ikan pelagis kecil, pelagis besar dan demersal. Komposisi jenis ikan laut yang didapatkan pada 4 Pasar Tradisional Kota Pangkalpinang yaitu sebanyak 5286 individu ikan. 1296 individu ikan di Pasar Ratu Tunggal Blok Kranas, 1927 individu ikan di Pasar Pagi Pangkalpinang, 1035 individu di Pasar Rumput, dan 1028 individu ikan di Pasar Parit Lalang. Berdasarkan hasil penelurusan di website IUCN, status konservasi jenis ikan laut yang diperdagangkan di pasar tradisional Kota Pangkalpinang terdapat enam kriteria yaitu sebanyak 45 spesies ikan tergolong Least Concern (LC), 3 spesies yang tergolong Near Threatened (NT), 3 spesies yang tergolong Data Deficient (DD), 3 spesies yang tergolong Vulnerable (VU) dan 1 spesies yang tergolong Critically Endangered (CR).

Abstract

Mangrove crabs (Scylla serrata) and (Scylla tranqueberica) are species that live in mangrove ecosystems. Mangrove ecosystems have a very important role for mangrove crabs, namely as habitat, foraging and spawning grounds. Mangrove crabs can grow and develop in mangrove forests because there are small organisms that become their food. Mangrove crab cultivation is the enlargement of mangrove crabs that are not ready for production using the container method. The container method is the maintenance and enlargement of mangrove crabs using multilevel containers, one of which is to make it easy to control the growth of mangrove crabs this study aims to analyze the growth rate of mangrove crabs (Scylla serrata) in the apartment caught by Selindung River fishermen for eight weeks. Parameters observed included absolute weight growth, absolute carapace width, and water quality such as salinity, temperature, pH, and dissolved oxygen levels. The results showed that the absolute weight growth of male and female crabs was significantly different, with male crabs having an average carapace width of 104 mm and female crabs 54 mm. This growth is influenced by the moulting process, where the crabs replace the old carapace with a new, larger one. The study found that feeding frequency greatly influenced the growth of carapace weight and width. Specific Growth Rate (SGR) of male crabs was highest at 1.14% per day, while females reached 0.75% per day. Male crabs showed a faster growth rate than females, due to higher metabolic activity. Mangrove crab survival rate reached 100%, indicating the apartment method was effective in supporting growth and survival. During the study, water quality remained in optimal condition with salinity of 27-29‰, temperature of 30-33℃, pH 6.1-6.8, and DO 5.5-6.3 mg/L. In conclusion, the apartment system for mangrove crab aquaculture is effective in improving the growth and survival of mangrove crabs in Selindung River.

Abstract

Open access to marine resources causes people to fish without control and ignore conservation and trade status. Theseactivities can cause population decline and population can lead to overfishing.. This is due to the lack of availability ofinformation and scientific data to fishermen regarding the conservation status of fish species. Therefore, this study aimsto identify and determine the conservation status of fish species caught using fixed gillnet fishing gear in PPN Sungailiat.Data collection was carried out in March-May 2024 at the PPN Sungailiat, Bangka Regency. This study uses survey andobservation methods with qualitative descriptive data analysis. The results showed that there were 13 families identified.The main catch in this study contained 12 species and by-catch there were 7 species. The conservation status of fishspecies caught on gillnet fishing gear remains at the Sungailiat VAT according to national regulations based on the Decreeof the Minister of Marine Affairs and Fisheries No. 01 of 2021 with unprotected status. Meanwhile, the conservationstatus of fish species based on IUCN has 6 categories, including 3 species of fish classified as Not Evaluated (NE), 5species classified as Least Concern (LC), 2 species classified as Near Threatened (NT), 2 species classified as Vulnerable(VU), 5 species classified as Endangered (EN) and 2 other species classified as Critically Endangered (CR). Meanwhile,the trade status based on CITES has 2 species of fish classified in Appendix II, namely Rhynchobatus australiae (palmray) and Rhina ancylostomus (barong shark). Based on the results of conservation and trade status, several managementapproaches need to be taken towards fisheries resources so that their populations are maintained.

Abstract

Cangkang kepiting, rajungan, dan udang vannamei merupakan limbah krustasea yang belum dimanfaatkan secara optimal di Pulau Bangka dan berpotensi mencemari lingkungan. Konversi biomassa dari limbah ini menjadi kitosan mendukung prinsip ekonomi sirkular. Penelitian ini mengevaluasi kualitas kitosan yang dihasilkan dari limbah krustasea berdasarkan rendemen, kadar air, dan derajat deasetilasi (DD), serta membandingkan dua metode berbasis FTIR untuk estimasi DD menggunakan rasio pita spektral A1320/A1420 dan A1655/A3450. Limbah cangkang (masing-masing 100 g) diproses melalui tahap demineralisasi (HCl 1,5 M), deproteinasi (NaOH 3,5%), dan deasetilasi (NaOH 60%) dengan dua ulangan per jenis. Hasil rendemen kitosan berturut-turut adalah 4,0% ± 0,5 (kepiting), 8,7% ± 0,5 (udang), dan 12,4% ± 0,9 (rajungan). Kadar air masih berada dalam batas SNI 7949:2013 (<12%), yaitu 6,4% ± 2,0, 10,7% ± 2,7, dan 6,3% ± 0,6. Berdasarkan rasio A1320/A1420, nilai DD masing-masing adalah 86,8% ± 0,4, 84,4% ± 0,1, dan 95,3% ± 2,5, seluruhnya melampaui standar minimum 75%. Sebaliknya, metode A1655/A3450 menghasilkan nilai DD jauh lebih rendah (<75%). Temuan ini menunjukkan bahwa limbah cangkang krustasea lokal memiliki potensi kuat sebagai sumber kitosan berkualitas tinggi. FTIR merupakan metode praktis untuk estimasi DD, namun tetap perlu divalidasi lebih lanjut, terutama dengan metode standar seperti ¹H-NMR.

Abstract

Microalgae, micro-sized plant organisms, play a crucial role in aquatic ecosystems. While many microalgae inhabit substrates or the bottom of water bodies, several types are planktonic. This study aimed to identify the types and abundance of microalgae in both sediment and water column habitats, as well as to analyse the environmental factors influencing their abundance. The research encompasses observations of water quality factors, microalgae abundance, relative abundance, diversity index, evenness index, and dominance index. Statistical analyses were using non-metric multidimensional scaling (NMDS) and Canonical Correspondence Analysis (CCA). The study was conducted in May-June 2022, with bi-weekly sampling at three points within each location for two months. Microalgae identified in the coastal area of Probolinggo belong to the Bacillariophyceae, Cyanophyceae, and Chlorophyceae classes. The highest microalgae abundance in sediment habitat was 58,472 ind/cm2, while in the water column was 4,118 ind/l. Diversity, evenness, and dominance indices in both sediment and water column habitats ranged from 1.93 to 2.61, 0.88 to 0.98, and 0.09 to 0.10, respectively. NMDS and CCA analyses indicate a graphical representation of the Bacillariophyceae class, demonstrating its prevalence across all sites.

Abstract

Kurau Village is one of the villages in Central Bangka Regency, Bangka Belitung Islands. The potential being developed in this village is people-scale shrimp ponds. One of these shrimp ponds is a group of vaname shrimp cultivators named Pokdakan Gempa 01. Pokdakan Gempa 01 cultivator group is relatively new because it was established in 2021 and there is still little knowledge about water quality management. Management of water quality in ponds is very important to increase the amount of shrimp productivity and minimize shrimp stress due to abnormal water quality conditions. Therefore, community empowerment programs are needed in order to increase community knowledge and increase productivity. The method used in empowering water quality management is a combination of counseling methods, mentoring and active community participation. At the end of the extension activities, an evaluation was held in the form of a Likert scale questionnaire (1-4), to measure partner satisfaction and the usefulness of the insights provided. Based on the results of the evaluation, it was found that the socialization carried out added insight to partners and was useful because it was in accordance with the needs of partners and the desire for sustainability of service activities from partners.
