Abstract

This research is motivated by the lack of information about the habitat preferences of pokea clams in Pohara River, Southeast Sulawesi. This study aims to determine the density, distribution pattern and habitat preferences of pokea clams in the Pohara River, Southeast Sulawesi. This research was conducted for 6 months (April-September 2011). Sampling of pokea, water quality, and sediment texture was carried out in the Pohara River and analyzed at the FPIK UHO Laboratory. The density and distribution of pokea were calculated using a standard formula and analyzed using Mann Whitney and Chi Square respectively, while the habitat preferences based on different substrate textures were analyzed using Principal Component Analysis (PCA) and Cluster Analysis (CA) in the Multivariate Statistical Package (MVSP). The results showed that the density of pokea clams ranged from 117±96.78-816±594.84 ind/m2 which was distributed in cluster over the entire cross-section of the river. Pokea clams were found in all substrate textures from gravel to clay. The habitat preference of pokea clams indicated by the highest density was found in the clay texture. Pokea clams relatively do not like the habitat of coarse sand and gravel texture which is characterized by pokea population with the lowest density

Abstract

The distribution of molluscs in Lake Sentani depends on their broad adaptability, dispersal ability, and zoogeographic history and ecological conditions. Ecological conditions in Papua have undergone many changes after the passage of special autonomy. A study on mollusk groups used by the community was carried in May-June 2018. Several government programs that require new land clearing for settlements, infrastructure development and agricultural areas have resulted in the conversion of sago forests, rivers, swamps, mangrove forests and lakes as places of interest. New settlements and shopping centers, consequently the degradation of Lake Sentani is unavoidable. Lake Sentani is currently under a lot of pressure from both internal and external factors. Some observers of lake ecology generally only conduct studies on water quality, but have not studied much of the fauna diversity, the potential of the lake's biological resources, let alone study the diversity of mollusc species and the types used by the community and the threat to the sustainability of the mollusk groups that are used. The public's understanding of the existence of Molluscs from an ecological and economic point of view has contributed greatly. From the survey results in Lake Sentani, the types used by the community are: Thiara sp. Pomacea canaliculata,  Pilsbryoconcha exilis, Bellamya sp, and Faunus sp. in the in-let area. Utilization of mollusk groups as a source of  family economy is also the second source of protein after fish, while in mountainous areas, certain types of mollusk  shells are still used as a legally valid medium of exchange locally.

Abstract

Seagrass is a community that consists a large number of organisms which associated within. Organisms associated with seagrass are gastropods. The purpose of this research is to determine the structure of gastropods community at seagrass on Pulau Panjang, Jepara. Exploration methods was applied and data was analyzed descriptively. The location of research are divided into 3 locations based on 3 different densities of seagrass : sparse, medium and dense. Every location consists of 4 stations with 3 repetitions. The research was held during Desember 2014. Sampling using quadratic a frame size of 1x1 m. The result, there are were 15 genera gastropods of 8 families as followed Trochus (Ciridae), Strombus (Strombidae), Turbo, Astralium, Dentarene, Liotina (Turbinidae), Cantharus, Nassaria, Engina  (Buccinidae), Cerithium, Rhinoclavis, Clypeomorus (Cerithiidae), Morulla (Muricidae), Columbella (Columbellidae), and Neritodryas (Neritidae). The abundance in location I 108.75 ind/????2 with dense of seagrass density, location II 91 ind/m2 with medium of seagrass density, and location III 47,25 ind/m2 with rare of seagrass density. Index value of Gastropod diversity classified medium category, index value of gastropod similarity classified high category, it means abudance from each spesies can be said to be similar, and evenly distributed and not on domination by a specific species.  Community similarity index classified in the category of medium to very large

Abstract

Microorganisms that live in association with marine invertebrates are able to produce a compound similar  to those produced by marine invertebrates and are thought to be potential as bioactive materials. Supplement  extracts from the Photobacterium phosphoreum bacterial culture have been shown to have antibacterial activity. The purpose of this study was to determine the anti-bacterial activity of the chloroform extract of Photobacterium  phosphoreum biomass against pathogenic bacteria Bacillus substilis, Staphylococcus aureus, Salmonella sp. and  Escherichia coli. The extraction process was carried out by the liquid-liquid extraction method. Fractionation was  performed using Open Column Chromatography (KKT). The antibacterial activity test was conducted by the agar diffusion method according to Kirby-Bauer. The results showed that for the antibacterial activity test of crude  extract, the largest inhibition zone diameter occurred in Escherichia coli with a concentration of 50 µg / disk at 24 h incubation, namely (9.80 ± 0.75 mm), while the smallest inhibition zone diameter occurred in Salmonella sp. by  giving a concentration of 10 µg / disk at an incubation time of 48 hours, namely (6.03 ± 0.05) mm. Of the 6  fractions resulting from crude extract fractionation, it was known that fraction 5 was the most active fraction and  inhibited the growth of the tested bacteria. The largest inhibition zone diameter occurred in Escherichia coli (9.83  ± 0.28) mm, while the smallest inhibition zone diameter occurred in Salmonella sp. (8.63 ± 0.20 mm)

Abstract

During a 4-weeks period oyster spat at- tached on shell and stone collectors but not on roofing tile  submerged in estuarine and marine habitats. Collectors made of stone (rough surface) were better than collectors  of shell in terms of number of settled spat. The oyster spat settled at highest density on collectors close tothe sea.  The average growth in terms of weight was significantly different on the two types of collectors. The largest oysters  occurred on shell collectors near the river
