SEBARAN SPASIAL KEMUNCULAN DUGONG (DUGONG DUGON) DI PULAU BANGKA

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
