Dugong merupakan satu dari 35 jenis mamalia laut yang dijumpai tersebar di perairan Indonesia khususnya di habitat padang lamun. Dugong merupakan biota yang dilindungi secara nasional berdasarkan Peraturan Pemerintah No.7 tahun 1999 tentang Pengawetan Jenis Tumbuhan dan Hewan yang telah diperbaharui oleh Permen LHK No.P 20 Tahun 2018 tentang Tumbuhan dan Satwa Liar. Dugong di Pulau Bangka sangat erat kaitannya dengan keberadaan nelayan yang juga memanfaatkan laut untuk memenuhi kebutuhan hidupnya. Penelitian Distribusi dugong dengan pendekatan survei untuk mengidentifikasi sebaran dan lokasi kemunculan Dugong sebagai dasar untuk penyusunan rencana konservasi belum pernah dilakukan. Sebaran kemunculan dugong di Pulau Bangka secara spasial yang terekam adalah di sekitar pulau pulau kecil di Selatan Bangka Hingga ke Pulau Maspari yang terletak berbatasan dengan Provinsi Sumsel, dan bagian tengah bangka terdapat di sekitar Pulau Panjang dan Pulau Ketawai, dengan ciri khas biasanya terdapat padang lamun sebagai ciri lokasi kemunculan dugong. Mayoritas lokasi kemunculan dugong bersinggungan dengan lokasi penangkapan ikan yang dilakukan oleh nelayan di Pulau bangka, sehingga diperlukan pengaturan lebh lanjut mengenai wilayah pengelolaan dan wilayah penangkapan ikan. Rendahnya persepsi kesadaran masyarakat terhadap keberadaan dugong dan termasuk untuk menjual serta mengkonsumsi dugong masih menjadi kendala atau halangan secara social di masyarakat maka perlu ada edukasi lebih lanjut dari segenap pemangku kepentingan untuk membangkitkan kesadaran masyarakat untuk menjaga keberadaan dugong.

Overfishing of wedgefish greatly affects its population and the balance of the marine ecosystem. This is exacerbated by their relatively low fecundity, slow growth, and late maturity results in one of the lowest population growth rate within elasmobranch species. However, lacking database information results in insufficient regulations and surveillance of wedgefish fishing. The current situation is feared to the risk of wedgefish’s survival, especially in Bangka Belitung Islands, Indonesia. Fundamental to a database is the accurate identification of wedgefish species based on mitochondrial DNA (mtDNA) analysis. This study aimed to use DNA barcodes to identify, determine the conservation status, and the status according to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). We collected samples including unidentified fin samples from confiscated illegal fishing catches, the traditional markets and fishing docks, South Bangka. In this research, we used DNA Barcoding (mitocondrial DNA, COI gene) to identify and examine of wedgefish samples. The tissue samples used in this study were identified as species listed in CITES Appendix II, they are Rhynchobatus australiae, Rhynchobatus springeri and Rhina ancylostoma. According to the IUCN Red List, 100% of the wedgefish species found are Critical Endangered at the global level.

This study aims to determine the quality of salt and classification of salt allotment produced from the South Bangka waters. The time and place of this research was conducted in October 2019 to January 2020 in the area of South Bangka Regency which included Mempunai Beach, Puding Beach, Kubu Beach, Batu Perahu Beach and Tanjung Kemirai Beach. Sea water from the five locations was crystallized into salt using the evaporation method with the help of the fuel heat. Then the salt from the crystallization process was carried out to the laboratory analysis and organoleptic test to see the levels of NaCl and the condition of the salt which includes odor, taste and color. The results showed the quality of salt produced from the five locations based on NaCl levels was in the category of K3 salt quality with NaCl levels from each location ranged from 65.51% -75.98%. Whereas visually it falls into the K1 salt quality category for salt produced from Kubu I, Kubu III and Tanjung Kemirai beaches. Test parameters such as the smell and taste of the salt produced have met the salt quality requirements for iodized consumption salt quality requirements according to SNI 4435:2017. Overall salt quality seen from the texture of the salt produced has a smooth texture. Allotment of salt produced from the five locations, both from the level of NaCl and the quality of the odor, taste, and color, is suitable for the management of fishery products in the form of salted fish.
