Abstract

Uca spp. are unique crab species marked with asymmetry cheliped. Major and minor cheliped has different function. The size of Major cheliped are several times of the minor ones (cheliped dominance pattern). Each species has different pattern of cheliped dominance. This study was to know the pattern of cheliped dominance on three Uca species. Major and minor cheliped length from twenty male individuals of U. dussumieri, U. vocans and U. perplexa were examined. The pattern of Cheliped dominance was obtained by comparing the major cheliped length to minor cheliped length. The two-tailed single sample t test showed similar cheliped dominance pattern within Uca species (P>0.001). While Kruskal-Wallis test showed different cheliped dominance pattern between Uca species (P>0.001). The cheliped dominance pattern of U. dussumieri, U. vocans and U. perplexa are 5.09, 4.24 and 4.75.

Abstract

Portof Tanjung Intan Cilacapis one of four major international shipping ports located in JawaIslandand among 85 ports throughout Indonesia. International shipping ports are exposed for non-indigenous species including barnalces as a consequence of shipping traffic. Barnacle is the most common marine fouling found in ship’s hull and ballast water of ocean going vessel. This work was aimed at knowing which barnacle species were passively transported on such vessels hulls, in order to map and monitor non-indigenous species invasion in the area. Four vessels of different origins were investigated between April and November 2009. Among four vessels, three of them were clean. A cosmopolite non-invasive species were found on a ship of Ukrainan origin, Amphibalanus amphitrite., which also occur dominantly in the port of Tanjung Intan Cilacap. This port was considered at no introduction risk of non-indigenous species.

Abstract

The objective of this study was to determine the effect of paklopbutrazol concentration and fertilizer on plant height and flower quality of potted chrysanthemum. The experimental method was used with factorial design. The first factor was paklobutrazol with the concentration as follow:  0, 100, 200, and 300 ppm. The second factors were cow, chicken, and goat manure. Parameters observed were plant height, time of flowers emerging, flower diameter and freshness. The results showed that certain concentration of paklobutrazol might inhibited plant height, time of flowers emerging, and shortening of flowers freshness, while chicken manure fertilizer spurred flower diameter.

Abstract

Isoflavone has multiple beneficial effects on human health, especially as antioxidant and anticancer. Biotransformation of two enantiomers (CE1 and CE2) of cis-isoflavan-4-ol by E. coli JM109 (pJHF108) carrying a biphenyl dioxygenase gene from P. pseudoalcaligenes KF707 produced two products and they were designated as CM1 and CM2. They had retention time at 11.9 and 14.6 min, respectively, and same absorption peaks at 204, 220 and 275 nm. CM1 and CM2 had [M-H2O+H]+  at m/z 225. Based on the molecular mass, hydrolysis products, and previous report, this study proposed that epoxidation occurred on cis-isoflavan-4-ol. Chloroform extraction was done to improve the stability of CM1 and CM2.

Abstract

Vibriosis is a bacterial disease generated by Vibrio sp., particularly V. harveyi that becomes the biggest cause of up to 100% shrimp mortality. Using antibiotics as the curative step is not applicable anymore, because of the residual effects to the shrimp and environment and the resistant effects to the humans as well. The purpose of this study was to screen potentially probiotic from strain Vibrio sp. that could inhibit V. harveyi as an effort of handling vibriosis diseases. Water sample from the shrimp ponds were isolated and purified in SWC-agar and TCBS-agar and then were incubated overnight at the room temperature. Bacterial concentrations were calculated using MC Pharland method and spectrophotometer. In vivo test was conducted for the best candidate of potential probiotic isolate, i.e. CP1. Challenged test was leaded within 4 different bacterial concentrations as the treatments and 2 replications using 10 shrimps as the tested organisms per aquarium. The treatments were 107 CFU/ml CP1 VS 107 V. harveyi MR5339 RifR (1), 106 CFU/ml CP1 VS 107 V. harveyi MR5339 RifR (2), 105 CFU/ml CP1 VS 107 V. harveyi MR5339 RifR (3) and PBS (4) as the control.  Our study showed that the Survival Rate of the tested organisms was 90% in the treatment 1. This result indicated the capability of growth inhibition of the candidate probiotic bacterium against V. harveyi. Presumably, Vibrio sp. could be used in the vanamei culture as the probiotic. Finally, the candidate probiotic bacterium was identified as Vibrio furnissii.

Abstract

I expressed the distribution, broad habitat association, and ecotourism potential of herpetofauna based on four habitat types on Ketenger-Baturraden,MountSlamet,Central Java. The data was gathered by opportunistic searching. Sorensen index was used to determine similarity between communities; and cluster analysis was used to determine the habitat utilization. As the results, 35 species were recorded, comprising 16 frogs, 11 lizards and 8 snakes. The species richness was decreased from natural forest to habitat types that open and having homogenous vegetation. The herpetofauna communities between natural forest and limited production forest had the highest similarity (50%). The natural forest is important habitat and should be conserved. Based on habitat types, there were nine groups of herpetofauna. The ecotourism potential of herpetofaunal richness on Ketenger-Baturraden is not yet exploited.

Abstract

Study on distribution of benthic foraminifera in Gili Air, Gili Meno and Gili Trawangan,Lombokwas held on February 12 – 15, 2008. Samples were collected respectively in the each side, including Northern, Eastern, Southern and Western part of Gili by using Van Veen Grab. Every side of the islands was collected three samples within 10 meters of clearance of each location. Thus, the collected samples of the three Gili were totally on 36 samples. The ecological parameters were also being measured, i.e. depth, temperature, salinity, pH and turbidity. The number of collected specimens of foraminifera was totally 46197 and the most specimen belongs to Suborder Rotaliina (423026 specimens). Then, 2137 specimens were recognized under Suborder Milioliina and the others 1036 specimens belong to Suborder Textulariina. The collected specimens consist of 49 species of 29 genera, which composed from Suborder Rotaliina (25 species in 20 genera), Suborder Milioliina (20 species, 7 genera) and Suborder Textulariina (4 species 2 genera).
