Abstract

Giant gourami has been widely cultivated across Java Island, including in Banyumas and Ciamis Regencies. However, information genetic characters of both populations were not available. Therefore, this study aims to evaluate molecular characteristics of giant gourami from Ciamis and Banyumas. A purposive random sampling was done Molecular characterization was performed using randomly amplified polymorphic DNA. Molecular data were analyzed statisticaly. Both populations were genetically different and they have high genetic diversity within population. Based on the high genetic diversity of giant gourami from Ciamis and Banyumas populations, it would be very good to crossbreed between those both to produce high quality offspring.

Abstract

The objective of this research was to assess the response of Jatropha curcas to indigenous Arbuscular Mycorrhizal Fungi (AMF) and P fertilizers applications in former coal mine fields. This study used a single factor Randomized Block Design which is a combination of mycorrhiza and P fertilizer consisting of 10 levels (without FMA and without P fertilizer, without FMA and 25% recommended doses of P fertilizer, without FMA and 50% recommended doses of P fertilizer, without FMA and 75% recommended doses of P fertilizer, without FMA and 100% recommended doses of P fertilizer, FMA and without P fertilizer, FMA and 25% recommended doses of P fertilizer, FMA and 50% recommended doses of P fertilizer, FMA and 75% doses of P fertilizer, FMA and 100% recommended doses of P fertilizer), with recommended doses is 150 Kg SP 36 / ha The observed variables were N, P, K uptake and Jatropha curcas yield. The results showed that the symbiotic of Jatropha curcas with FMA combined with 50% recommended dose of P fertilizer gave the best N, P, K uptake and Jatropha curcas yield in Coal Post-Mining Land.

Abstract

Estuary is one of an aquatic ecosystem that has something unique, because it is a meeting area of the fresh and sea water. This study aimed to analyze phytoplankton structure community in estuary of Bengawan Solo River, conducted from January to June 2001 at ten stations distributing from river, estuary and sea. Data analysis was done to evaluate species composition, abundance, diversity, evenness, and dominance indices of the phytoplankton. Clustering based on the phytoplankton abundance was done by using Bray Curtis index. Based on the study, the phytoplankton in the estuary of Bengawan Solo River consisted of 5 classes and 33 species such as. Bacillariophyceae (19 species), Cyanophyceae (2 species), Crysophyceae (3 species), Chlorophyceae (3 species) and Dinophyceae (6 species). Phytoplankton abundance varied, at the river station was 1026-3005 inde/l, the estuary was 5098-19727 inde/l, and the sea was 4206-8697 inde/l. Diversity Index (H) was 0, 29-2, 24, Evenness Index (E) was 0, 02-0, 98, and Dominant Index (C) was 0, 12-0, and 88. There were 3 groups according to clustering analysis based on the phytoplankton abundance using Bray Curtis Index (55%).

Abstract

This study aims to determine the species of freshwater shrimp and habitat character in District West Aceh. The research conducted in April - July 2014, include at seven observation site, Used purposive sampling methode. At each station, samples were collected for 30-45 minutes with a length of 3-5 m sampling area along the river in a direction against the current. Samples were taken to the Basic Biology Laboratory of STKIP Bina Bangsa Meulaboh, for further identification. The identification of shrimp based on morphological features, taxonomic characteristics and body measurements. Shrimp habitats in each site are described and documented. There are five species of freshwater shrimp found in West Aceh, ie: Macrobrachium rosenbergii, M.empulipke, M. equidens, M. australe, and M. lanchesteri. There are different species of Freshwater shrimp found in different habitat characters.

Abstract

This study aims to compare several extraction methods to obtain the active component of the qualitative Curcum rhizome. The data obtained were analyzed using descriptive analysis. Curcuma rhizome used comes from 4 types of plants Curcuma xanthorriza (temulawak), Curcuma domestica (turmeric), Curcuma mango (temu mangga) and Curcuma zedoaria (temu putih). The extraction method used consisted of maseration, reflux and soxhlet method. From the research result it was found that all three extraction methods can be used (maceration, soxhletasi and reflux) to extract the curcuma rhizomes. The result of phytochemical test of metabolite secondary detectable and very strong both of atsiri and non-essential oil group is using reflux method then new method of soxhletasi and then maceration method.
