Abstract

 Tuing is a remote  location in the Riau Silip District, Bangka Regency. Tuing has potential of marine fishery resources as well as tourism development potential to be developed in Bangka Regency. In addition to the resource potential of natural resources,moreover it is also rich in tin because almost all seas from 0-4 nautical miles have been issued by marine mining permits. This study aims to determine the suitability of mangrove land in Tuing to be developed as a tourist location. Data taken includes mangrove tourism suitability data, such as vegetation and environmental parameters. Based on the results of the analysis of ecotourism location suitability in the eight stations, stations 1,3,5,6 and 7 have inter-values of 86-96% or in the S1 category: with grades 80-100% (Very Appropriate), while the index values are different at stations 2 and 8 have a value of 52-69% in the S2 category: with a value of 60-80% (quite appropriate). Ecologically, there are 4 mangrove species, Soneratia alba, Rhizophora apiculata, Avicennia sp., Rhizophora mucronata. Accordingly, recommendations for development strategies the need for regulation of mining activities around the Tuing mangrove forest area, training for tourism-related businesses with local resources and ordinarily need more funding to provide support facilities and infrastructure.

Abstract

Dog conch (Strombus turturella) is one of important sources of fishery commodities with  high economic values in Bangka Belitung. The needs of Dog conch as consumption still depends on fishermen harvest since its aquaculture has not been cultured until now. This study aims at determining behavior and feeding habit of dog conch. The study was conducted in July 2014 to January 2015. The experiments passed some stages 1) samples was taken in the field by hand collecting, 2) the experiment of seagrass consumed preference, 3) feeding behavior, and 4) Analysis of the stomach contents. The results indicate dog conch does not consume seagrass immediately, but detritus and microalgae species of Thalassiosira sp., Synedra sp., Nitzschia sp., Navicula sp. Dog conch eats by put the probiosis of the shell, then it grinds sediment layer, seagrass leaves and shells of other individuals as source if food. Dog conch behavior from beginning to  ending of the observation includes several stages: 1) Initial treatment actively foraging, 2) Individuals dog conch assembled or in pairs, 3) on the second day, the dog conch hoards himself on the base of the substrate and only elastic probiosis which occasionally appear occasionally at the substrate bottom.

Abstract

Lamun Cymodocea serrulata merupakan salah satu tumbuhan berbunga yang sudah sepenuhnya menyesuaikan diri untuk hidup terbenam di dalam laut. Penelitian ini bertujuan untuk menganalisis tingkat kelangsungan hidup dan laju pertumbuhan lamun Cymodocea Serrulata yang ditanam pada Media Akuarium. Penelitian ini dilakukan pada bulan Maret – Mei tahun 2019 di laboraturium Manajemen Sumberdaya Perairan, Universitas Bangka Belitung. Hasil penelitian tingkat kelangsungan hidup lamun Cymodocea serrulata selama 2 bulan  tertinggi pada perlakuan A3 dengan pemberian nutrien pupuk organik sebanyak 15 gram dengan tingkat keberhasilah hidup yaitu 96,30%. Laju pertumbuhan daun lamun Cymodocea serrulata tidak terdapat perbedaan nyata pada setiap perlakuan dengan nilai signifikansi 0,237 (p > 0,05).  Laju pertumbuhan lamun Cymodocea serrulata yang diberi tambahan nutrien berupa pupuk organik berkisar antara 0,842 cm/bulan – 1, 217 cm/bulan. Penelitian ini menunjukkan bahwa pemberian nutrien berupa pupuk berdampak positif terhadap pertumbuhan lamun Cymodocea serrulata. Kata Kunci:, Cymodocea serrulata, lamun, nutrien,  pertumbuhan, pupuk.
