Abstract

ABSTRACTTraditional Role and Spring Sacredness For Water Conservation in the slope of MountCiremai. Kuningan Regency proclaimed as conservation regency. Consequently the way oflife in this regency should follow non-pollutant producing or non-environmental damagingactivities. This regency is intended to perform organic agriculture and water tourism (falls,lakes, and springs) destination. For those purposes, Kuningan Regency should maximize thepotency of natural catching and reserving rainfall area to be used efficiently thereafter.Kuningan Regency is surrounded by five DAS derived from the slope of Mount Ciremai. Atleast there are three sacred springs in Kuningan Regency including Balong Dalem, BalongCibulan, and Sumur Tujuh. All of them are located in Jalaksana District. Balong Dalem andSumur Tujuh are the centre of traditional ritual called kawin cai or mapag cai. The ritual implyingawareness of the society human life depend on water supply sustainability. Comparativeanalysis between sacred and non-sacred springs indicated that the sacred springs are betterand more conserved condition than that in non-sacred spring (Balong Darmaloka). However,there were still unique and threatened animals in sacred springs. Therefore, traditional rolesand spring sacredness in Kuningan are still needed for spring conservation. Unfortunately,many of governmental activities exhibited unawareness of local government to the springconservation which it should become their responsibility.Key words: Traditional ritual, water conservation, Ciremai, Kuningan Regency

Abstract

First year re-monitoring conducted in 2009 through measuring the entire individuals that have been given numbersand giving new numbers to individuals with stem diameter more than 5 cm. The result of re-monitoring indicatesthat the numbers of populations and species increased, but not significant. Mortality rate observed 7 individualsper hectare (about 1.20 %); whereas natality rate observed 25 individuals per hectare (about 2.52 %), which isregarded as low. Basal area observed in 2008 was approximately 26.55 m2 per hectare and it increased to about27.34 m2 per hectare in 2009. Total number of individuals in 2009 was 595 individuals from 119 species, 86genera, and 44 families with diversity index of 3.60 (H’). Elaeocarpus petiolatus (Elaeocarpaceae) and Planchoniavalida (Sapotaceae) are new additions. Altingia excelsa is still the dominant species.Keywords: Forest dynamics, rasamala permanent plots, Bodogol, GPNP

Abstract

ABSTRACTImprovement of Bracirwnuspficatifis Mueller 1786 Static Culture Productivity byOptimization of Food vpe and Food Concentration. A study to optimize the standardculture procedure by optimization of feeding regime (selection of the best type ofmicroalgae and its concentration used for diet of Brachionus plicatiliz diet) wasconducted in order to support more stable and higher yield production of B. plicatilisculture. A serial experiment was done in two consecutive stages. On each stage, B.plicatilis zooplanktons were cultured in batch system of 30 x 30 x 50 cm3 aquarium,initial density of 10 ind./mL, and constant aeration rate of 200 mLIminute. The density,egg ratio, water quality parameters of the culture (dissolved oxygen, pH, ammoniumlevel, nitrite level, nitrate level) were measured daily. On the first experiment, B. plicatiliscultures were fed on lo6 cells/mL Chlorella sp., Nannochloropsis sp., Tetraselmis sp.,and a combination of those three micro-algae. The results showed that optimum culturedensity was obtained in the culture fed on Nannochloropsis sp. (68*2) indImL on day 5of culture period and the density was significantly different from the other treatments(pc0.05). On the second stage, B. plicatilis cultures were fed on Nannochloropsis sp. infour different concentrations: 1 OS, 1 06, 1 07, and 1 08cells/mL. Optimum culture density(407k9) ind./mL was obtained in the culture fed on 1O7ce1ls/mL Nannochloropsis sp. onday 7 of culture period and the density was significantly different from the other treatments(p<O.O5). It can be concluded that the optimum culture condition (optimum density andmore stable water quality parameter such as NH; and NO2 of B. plicatilis batch culturescan be obtained by optimization of feeding regime using 1 O7 cells/mL NannochloropsisSP .Key words: Brachionus plicatilis, Nannocloropsis sp., Tetraselmis sp., Chlorella sp.,microalgae concentration, water quality, productivity.

Abstract

Diatomite Sangiran is diatom fossil rich sediment. The aim of this research was to study the diversity of fossildiatoms from Sangiran, Indonesia based on morphological characteristics. Samples were taken from lower, middle,and upper sediment layers based on their different physical features with three replications each. Diatomiteextraction was performed following modification of Setty (1966) and frustule counting was accomplished by censusmethod. There were total 50 species found in diatomite layers. The diversity analysis showed that highest speciesrichness (21-22), diversity (1.35-1.47), and evenness index (0.44-0.48) were belong to the lower layer. The highestfrustule abundance (9.66x107-1.43x108 frustules/gram) and dominance index (0.67-0.72) were belong to themiddle layer. On the other hand, highest centrales:pennales ratios (0.73-1.11) were belong to the upper layer. Thesediment layers signified an obvious indication of gradual changes from marine to freshwater environment.Dendrogram analysis using MINITAB.v.15.1.2 software denoted similarity between lower sediment layer and theyounger layers was 72.12%; while similarity between middle and upper layers 92.63%.Keywords: diatom, diatomite, diversity, morphology, Sangiran

Abstract

ABSTRACTTransformation Strategy for Indonesian Indica Rice in Attempt to Discover Drought-TolerantRelated Genes Using of Transposon Ac/Ds. Attempt to identify, isolate the gene, and study forgene function for several agronomical traits have been done including some drought toleranttraits. Japonica rice cultivars have been used due to its higher efficiencies compared withindica cultivars. Two plasmids namely pNU400 and pUR224 were used to generate mutants ofthese cultivars (Batutegi dan Kasalath cultivars). Those plasmids contain an element calledActivator (Ac) and Dissociator (Ds) respectively. The pNU400 contains GFP (green flourescensprotein) as a selectable marker, whereas the pUR224 contains hygromycine resistant gene andgusA as a reporter gene. Each plasmid was transformed into rice genome of Batutegi andKasalath cultivars by Agrobacterium mediated transformation using three methods oftransformation (A, B and C). The transformation method A was not suitable for both cultivars,where none of plantlets were produced from pNU400 and pUR224 plasmids. The transformationmethod B produced some plantlets from the Kasalath cultivar only using pUR224 plasmid.The transformation method C was the best method to produce transgenic plants from bothcultivars (Batutegi and Kasalath), using both plasmids (pNU400 and pUR224). The PCR analysisshowed that 19 and 9 plants of Batutegi and Kasalath contained both gusA and hpt genesrespectively. None of those plants contained of gusA gene. Southern blot analysis revealed 3independent lines from Batutegi dan 7 independent lines from Kasalath. The integration of Actransposon was analyzed based on expression gfp gene when observed under UV dark reader.This research has proved that indica rice cultivars, especially the Batutegi cultivar of Indonesianorigin, could be transformed. The cultivar could be used as plant model for the indicatransformation.Key words: transformation, drought tolerant, indica rice, Ac/Ds transposons, Agrobacterium.

Abstract

ABSTRACTRecently, food preservation especially for meat is becoming one of the subjects of food technology that is still developed. Organic acids is commonly used for food preservative. Meat is easily destroyed mainly by Staphylococcus aureus and Escherichia coli. Oyster Mushroom (Pleurotus spp.), well known as an edible mushrooms is one of the food resources that have antimicrobial activity. The application of oyster mushroom extracts in chicken meat is done using extract concentrations of 0%, 12.5%, 18.75%, 25%, 31.25% and 37.5% where 12,5% is the MIC to inhibit E. coli and S. aureus. The results showed that the application of brown oyster mushroom extracts with concentration of 31.25% can mantain freshness of chicken meat for 12 hours of storage at room temperature (26oC) with the total number of microbes of 8.6 x 105 cfu/g, the total number of E. coli of 0.3 x 101 cfu/g, the total number of S. aureus of 7.7 x 101 cfu/g. It was appropriate with Indonesian National Standard ( SNI 3924:2009). It required the condition such as no decomposition, pH 5.53, color organoleptic value of 3.42 (fair to good) and texture organoleptic value of 3.53 (fair to good).Keywords : oyster mushroom extract, antimicrobial, chicken meat preserving
