“…Mereka percaya bahwa kesuburan mangrove memberikan tangkapan melimpah dan terus-menerus di perairan sekitarnya. Memang nutrisi dan perlindungan yang disediakan oleh mangrove yang juga berperan sebagai nursery ground bagi ikan dan udang (Kurniawan et al, 2018), sehingga relevan jika mangrove tidak diganggu mendukung produksi udang dan rajungan berkesinambungan.…”

“…Meskipun sedikit dibandingkan kawasan hutan lainnya, mangrove memiliki manfaat yang besar bagi manusia baik secara langsung maupun tidak langsung. Manfaat tersebut dapat dirasakan masyarakat mulai dari penahan abrasi dn gelombang laut, penyedia oksigen, tempat hidup anak ikan dan udang hingga sumber pendapatan dari pariwisata (Kurniawan et al, 2018). Walaupun banyak manfaat, luasan mangrove semakin menurun dari tahun ke tahun.…”

“…Pertambangan timah lepas pantai juga memberikan kekeruhan pada perairan pantai. Namun terdapat pemanfaatan wilayah mangrove yang tidak ditemui di pesisir Pulau Bangka lainnya, yaitu adanya budidaya Kerang Darah (Anadara granusa) yang dikembangkan masyarakat lokal (Kurniawan et al, 2019).…”

Belo Laut Village has 3,337 ha of mangrove potential spread over three hamlet areas, namely Belo Laut, Tanjung Punai, and Sukal. On the muddy beaches around the mangroves, the community has developed extensive cultivation of blood clams (Anadara granusa). The existence of cultivation in mangrove areas also has the potential to affect the existence of mangroves in the area. For this reason, it is necessary to know the perception of shellfish cultivators on mangroves and the reality of the condition of mangroves in Belo Laut Village so as to provide an overview of the potential for mangrove destruction due to Blood Clam cultivation. Data were collected by interviewing shellfish farmers in Sukal and Tanjung Punai Hamlets. The production of blood clam cultivation has become a new source of economy in Belo Laut Village which is carried out by almost all family heads in Sukal and Tanjung Punai Hamlets. The community considers that the mangroves in Belo Laut village had not changed in quantity and there was no indication of their use other than for tourism. The perception and understanding of shellfish farmers not to disturb the mangroves were based on the protection of their main source of income as shrimp and crab fishermen.

Abstract. Leaf litter of mangrove has the potential for cellulolytic bacteria that are beneficial in aquaculture feed. Tin mining in Bangka Island impact for mangrove and allows for new strains of cellulolytic bacteria. Identification and safety evaluations are needed to knows the applied to aquaculture. This study aims to obtain and evaluate the potential impact on the aquaculture of cellulolytic bacteria from the Tukak Sadai mangrove, South Bangka. The effects were shown on the survival and clinical symptoms of fish through pathogenicity testing of the selected bacteria. This research was done from March 2017 until March 2018. Leaf litter was a sample taken from mangroves and isolated using 1% Carboxymethyl Cellulosa (CMC) media. Qualitative test of cellulase enzyme activity uses congo red and bacterial identification to use biochemical characterization with Microbact TM. There were six cellulolytic bacterial isolates from the mangrove leaves of Tukak Sadai, South Bangka. TSS4 isolates had the highest cellulolytic index of 26.4 mm compared to other strains. Biochemical characterization of TSS4 isolates show similarities with Bacillus cereus. Pathogenicity test on Bacillus cereus_TSS4 isolates show that it was not pathogenic with normal fish conditions until the end of maintenance, fish survival reached 100%, and no damage to internal organs occurred.Keywords: Bacillus cereus, mangrove leaf litter, pathogenicity, cellulolytic bacteriaAbstrak. Serasah daun mangrove memiliki potensi bakteri selulolitik yang bermanfaat pada pakan dalam akuakultur. Penambangan timah di Pulau Bangka berdampak pada hutan bakau dan memungkinkan strain bakteri selulolitik baru. Identifikasi dan evaluasi keamanan diperlukan untuk mengetahui penerapan pada budidaya. Penelitian ini bertujuan untuk mendapatkan dan mengevaluasi dampak potensial pada akuakultur dari bakteri selulolitik hutan bakau Tukak Sadai, Bangka Selatan. Dampaknya ditunjukkan pada kelangsungan hidup dan gejala klinis ikan melalui pengujian patogenisitas dari bakteri yang dipilih. Penelitian ini dilakukan mulai Maret 2017 hingga Maret 2018. Serasah daun merupakan sampel yang diambil dari mangrove dan diisolasi menggunakan media Carboxymethyl Cellulosa (CMC) 1%. Uji kualitatif aktivitas enzim selulase menggunakan congo red dan identifikasi bakteri untuk menggunakan karakterisasi biokimia dengan MicrobactTM. Ada enam isolat bakteri selulolitik dari daun mangrove Tukak Sadai, Bangka Selatan. Isolat TSS4 memiliki indeks selulolitik tertinggi 26,4 mm dibandingkan dengan jenis lainnya. Karakterisasi biokimia isolat TSS4 menunjukkan kesamaan dengan Bacillus cereus. Uji patogenisitas pada isolat Bacillus cereus_TSS4 menunjukkan bahwa tidak patogen dengan kondisi ikan normal sampai akhir pemeliharaan, kelangsungan hidup ikan mencapai 100%, dan tidak terjadi kerusakan pada organ internal.Kata kunci: Bacillus cereus, serasah daun mangrove, patogenisitas, bakteri selulolitik
