STRUKTUR KOMUNITAS VEGETASI MANGROVE DI PESISIR UTARA PULAU MENDANAU DAN PULAU BATU DINDING, KECAMATAN SELAT NASIK KABUPATEN BELITUNG

Mendanau Island and Batu Dinding Island are part of small island groups that have a high diversity and density of mangroves. Based on administratively, Mendanau Island is located in the coastal area of Simpang Pesak District, Belitung Regency, which consist of one large island (Mendanau Island) and 1 small island (Batu Dinding Island). The lack of data about potential, diversity, and community structure of mangroves on the north coast of Mendanau Island and Batu Dinding Island, therefore this research is needed as a database for planning, sustainability management of mangroves at the coastal area and small island. The data of mangrove vegetation was taken by purposive sampling method, with using line transect plot (LTP). Ilustration of sampling design is each line transect have 3 plot / kuadratic transect sized 10 m x 10 m (capling), 5 m x 5m (sapling), 1m x 1 m (seedling). The result showed that there are 12 (twelve) mangrove species were found: jenis S. alba, R. apiculata, R. stylosa, R. mucronata, B. gymnorhiza, X. granatum, L. littorea. S. hydrophyllacea, S. taccada, H. tiliaceus, Pandanus, dan I. pes-caprae. Mangrove community structure and mangrove condition on the North Coast of Mendanau Island, at several observation stations, was damaged (poor conditions), while the status of the mangrove conditions on Pulau Batu Dinding was still relatively good

HUBUNGAN KEPADATAN BIVALVIA DENGAN PARAMETER LINGKUNGAN DI PESISIR TANJUNG PURA KABUPATEN BANGKA TENGAH

The destructive fishing feared will give a negative impact on the survival of this organism. This study aims to analyze the density of bivalves, distribution patterns, and to analyze the relationship of bivalves with environmental parameters in Tanjung Pura village. This research was conducted in March 2019. The systematic random system method was used for collecting data of bivalves. The collecting Data retrieval divided into five research stasions. The results obtained 6 types of bivalves from 3 families and the total is 115 individuals. The highest bivalve density is 4.56 ind / m², and the lowest bivalves are located at station 2,1.56 ind / m², The pattern of bivalve distribution in the Coastal of Tanjung Pura Village is grouping. The results of principal component analysis (PCA) showed that Anadara granosa species was positively correlated with TSS r = 0.890, Dosinia contusa, Anomalocardia squamosa, Mererix meretrix, Placamen isabellina, and Tellinella spengleri were positively correlated with currents r = 0.933.

The Influenceof Oldan Iron Fish Trap Immersion On Fish Catches In Lake Kerinci Jambi Province

Desa Koto Petai adalah salah satu desa yang berada di dekat Danau Kerinci tepatnya di Kecamatan Danau Kerinci, aktivitas penangkapan di Koto Petai dilakukan pada pagi dan malam hari sesuai dengan alat tangkap yang digunakan masyarakat setempat. Alat tangkap yang terdapat di desa Koto Petai adalah tangkul/ pesap, jaring insang, jala, bagan tancap dan bubu/lukah.Tujuan dari penelitian ini untuk mengetahui perbedaan hasil tangkapan ikan nila dan mengetahui komposisi hasil tangkapan berupa berat, jumlah dan jenis ikan yang tertangkap terhadap lama perendaman bubu. Metode penelitian yang digunakan yaitu metode experimental fishing dan analisis data yang digunakan pada penelitian ini adalah analisis rancangan acak lengkap (RAL). Hasil penelitian pada analisis ragam menunjukan bahwa perlakuan lama perendaman tidak berpengaruh nyata terhadap rataan berat keseluruhan hasil tangkapan, sedangkan untuk hasil tangkapan ikan nila tidak berpengaruh nyata terhadap lama perendaman dan hasil uji Duncan menunjukkan bahwa berat hasil tangkapan perendaman 8 jam tidal berbeda nyata (P>0.05) dari perendaman 10 jam dan perendaman 12 jam. Berdasarkan penelitian yang telah dilakaukan disimpulkan bahwa lama perendaman bubu besi selama 8 jam menghasilkan tangkapan lebih optimal dengan ikan yang banyak tertangkap adalah ikan nila.

ABSTRACT Aditia (2021611001) The Community Structure of Fish in Lulak Stream and Gendir Stream of West Bangka Regency. (Supervisors: Wahyu Adi, S.Pi.,M.Si dan Andi Gustomi, S.Pi.,M.Si) The waters of the stream in west Bangka nowadays facing the threat of the deforestation or the fragmentation of the alteration of land function such as for the plantations, agriculture mostly for the program of rice field print that makes the forest area and the watershed threaten the fish habitats, for instance the Lulak stream and gendir stream in Kelapa, West Bangka regency. The goals of this study is to examine the diversity of the fish, examine the community structure and examine the relation between the waters quality with the fish diversity in Lulak Stream and Gendir Stream. The data was took and conducted in February 2020 using the gill net and dip net. The result showed that the diversity value has the index with the amount is 1,948 for Lulak Stream and 1,881 for Gendir Stream with the category is moderate. The community structure of fish in Lulak stream and Gendir stream was dominated by Cyprinidae with 5 species from 14 species based on what was found in both of the stream. There was 14 fish with 12 of fish species found in Lulak stream and 11 fish in Gendir stream that dominated by cyprinidae ( Puntius binotatus, Puntius lineatus, Cyclocheilichthys apogon dan Rasbora chepholataenia). The Physic and Chemistry factors in Lulak Stream and Gendir Stream supports the survival life of the cyprinidae that dominate both of the river.

ANALISIS STRATEGI PENGEMBANGAN PERIKANAN RAJUNGAN DI PANTAI PUDING BANGKA SELATAN

The swimming crab is a type of sea crab whose abudance is distributed almost evenly across Indonesian waters. There are aspect that need to be considered in the use of swimming crab resources, namely biological technical, and economical aspect. So, taht it can be done without endangering the sustainability of the resources. The research was conducted from April through July, 2018, in Puding Beach, South Bangka Regency. The primary and secondary data were obtained using 3 method of analysis, namely analysis of maximum sustainable yield (MSY), analysis of utilization rates, business analysis, and SWOT analysis. The result suggested that the MSY value was of 1,319.059 ton/year and the foptimum was 23,877.356 trips/year. This suggests that overfishing has taken place ang that the utilization of swimming crab resources has surpassed the limit of TAC. the fishing gear used by fisherman for catching swimming carbs in Puding Beach is the collapsible trap with the operating principle of one day fishing. Based on business analysis, it was found that the activity is profitable for the fisherman and tah business if feasible. The researchers also formulated 12 alternative strategies for crab meat business development in Puding Beach.
