This study is aimed to determine the effect of additional concentrate feed on the physical and chemical characteristicsof sunda porcupine meat. The material used is eight sunda porcupines (two males and six females) divided into twogroups of ration treatment, namely T0 (control ration) and T1 (T0 + koi fish pellets). Four porcupines (one maleand three females) were given control ration (T0) and four porcupines were given rations T1. The experimental designwas a completely randomized design. The meat physical characteristics measured were pH, tenderness, cookingloss, water holding capacity (WHC), meat color, and fat color. While meat chemical characteristics analyzed werewater content, ash, protein, fat, gross energy, calcium (Ca), phosphorus (P), iron (Fe), the content of fatty acids(EPA, DHA, Omega-3, Omega-6, Omega-9, and cholesterol), as well as the composition of amino acids. Data wereanalyzed by analysis of variance. The results showed no significant differences (P> 0.05) between male and femaleporcupine with both ration treatments (T0 and T1) on pH, tenderness, cooking loss, WHC, meat color, and fatcolor. The addition of koi fish pellets in the ration T1 decreased pH value (65.76) and cooking losses (37.88%), andincreased WHC porcupine meat (23.59%). Porcupine meat is quite tender with tenderness values of 3.63 kg / cm2(T0) and 3.26 kg / cm2 (T1). The averages of water content, ash, protein, fat, energy, Ca, P, Fe of porcupine meatwere not significantly different (P>0.05) in both treatments T0 and T1. The averages of fatty acids contents of porcupinemeat with T1 was not significantly different (P>0.01) from that of T0, but there was an increase in the concentrationof EPA, DHA, omega-3, omega-6, omega-9, and cholesterol in treatment of T1. Cholesterol content ofporcupine meat was lower than that of beef, pork, lamb, sambar deer, and java deer. No significant effect (P> 0.05)on content of amino acids in meat porcupine with T1 compared to that of T0.Keywords: Physical-chemical characteristics, meat, concentrate feed, sunda porcupine

Hybridization of wild diploid Musa acuminata Colla var malaccensis (Ridl.) Nasution as pollen source with teraploid Pisang Madu. Indonesia and South East Asia is the center of origin and genetic variability of bananas, specifically species Musa acuminata Colla. At least 15 varieties of wild Musa acuminata are found in Indonesia. Some of them have resistances for several diseases of bananas. One approach in banana breeding program is hybridizingbetween tetraploid parent and diploid parent of banana. This research was aimed to produce new triploid banana hybrid by crosses between tetraploid female parent âPisang Maduâ and wild diploid male parent Musa acuminata Colla var malaccensis (Ridl.) Nasution. From 302 crosses, 53.9% of crosses produced seeds. However, only 48.46% of seeds contained embryos, and only 1.27% of embryos grew and developed. Bunch weight and leaf length of hybridplants were not significantly different with female parent, tetraploid Pisang Madu. Plant height of the hybrids was not significantly different with male parent, wild diploid Musa acuminatavar malaccensis. Pseudostem diameter and leaf width of the hybrid plants were between female tetraploid parent and male wild diploid parent. RAPD profiles (DNA bands) of the hybrids were originated from the female parent, male parent and both parents were 38.46, 34.6, and 26.92%, respectively. The hybrids were confirmed to be triploids (3x=33).Keywords: banana, breeding, hybrids, tetraploid, wild diploid, Pisang Madu, Musa acuminata Colla var malaccensis (Ridl.) Nasution

Hylarana celebensis (Peters, 1872) is an endemic frog to Sulawesi, the species being a member of family Ranidae.Â The presence of the frog in its habitat is easily detected from its advertisement call; males usually call in a chorus, they call to each other in a large group. Bioacoustics of calls that a typical individual male of H. celebensis has not been described in detail, although it is very easy to find this species in freshwater swamps, permanent ponds, or slow-flowing waters in the lowland areas. The purpose of the bioacoustic analysis on H. celebensisâs calls that were recorded at Bahodopi area is to build a reference collection to be compared with H. celebensisâs bioacoustics to the other regions in Sulawesi. Because of the wide distribution of this frog in Sulawesi; population genetic structure of H. celebensis may also follow the population genetic structure of Ingerophrynus celebensis. Calls of H. celebensis have two types of calls, i.e. pure tone and pulse; however, pure tones have three variation, namely pure tone type 1, pure tone type 2 and pure tone type 3; however pulsed call has only one type.Â Keywords: Anura, Hylarana celebensis, bioacoustics, Sulawesi.Â

ABSTRACTThe Effect of Environmental Factors on the Horizontal and Vertical Movement of Frogs. Fourenvironmental factors (moon phase, air temperature, water temperature and air humidity) weremeasured to determine the impact of environmental factors on the dynamics of horizontal andvertical spread of the frog Rana erythraea, R. nicobariensis and Occidozyga lima in a wetlandarea of Ecology Park, LIPI Campus Cibinong. Observation was done follows transect line(100 meters long) and set along the edge of the lake where the habitat was more diversecompared to the other sites. Observations were carried out from July to November 2009. Theposition of individual frogs (distance from waterâs edge and height from the ground or water)was recorded and then grouped into intervals of 100 cm distance and height each. Correlationanalysis between the number of individuals per unit distance or height with environmentalfactors was measured using the statistical program SPSS version 16.0. The results of thisstudy proved that the air and water temperature as well as air humidity have significant effecton horizontal and vertical ecological distribution of R. erythraea and R. nicobariensis; whereasfour environmental factors had no impact on horizontal distribution of O. lima. The movementof R. erythraea was strongly positively correlated with air temperature, but strongly negativelycorrelated with air humidity; however the abundance of R. nicobariensis was strongly negativelycorrelated with air temperature and strongly positively correlated with air humidity. Mixedvegetation of species Leerxia hexandra and Eleocharis dulcis at a distance between 0-100 cmfrom the edge of the water and height between 0-100 cm from the ground constituted thepreferred microhabitat of frog species R. erythraea and R. nicobariensis.Key words: Environmental factors, Rana erythraea, Rana nicobariensis, Occidoziga lima,Ecology Park, wetland.

The current study is the first report on intraspecies analysis of L. plantarum from sayur asin in Indonesia using molecular approach. Three molecular techniques, i.e., restriction fragment length polymorphism (RFLP) 16S-23S rDNA intergenic spacer region (ISR), random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) and enterobacterial repetitive intergenic consensus (ERIC-PCR) were used to determine the intraspecies diversity of L. plantarum responsible for spontaneous fermentation in sayur asin. These methods were aimed to discriminate 46 isolates of L. plantarum isolated from sayur asin, including the type strain. PCR amplification of the 16S-23S rDNA ISR revealed two-bands profile of 800 and 600 bp specific to lactobacilli. RAPD-PCR and ERIC-PCR were very valuable in discriminating genetic polymorphism among L. plantarum isolates by producing bands ranged from 4-10 bands (360-2620 bp) and 6-12 bands (160-2900 bp), respectively. Dendograms generated from UPGMA cluster analysis based on RAPD-PCR and ERIC-PCR data showed that all isolates were grouped into three major clusters with 74% and 68.6% genetic similarity thresholds, respectively.The study indicated that strains belong to L. plantarum isolated from sayur asin were divided into three genotypic groups.ÃÂ Keywords: ERIC-PCR, Intraspecies, Lactobacillus plantarum, RAPD-PCR, RFLP 16S-23S rDNA ISRÃÂ

ABSTRACTBiological Activity of Enzymatically Synthesized Polyphenol Glycoside on Microbial Growth. We have studied an indigenous bacterial strain produced a glycosyl transfer enzyme (CGTase) yielding polyphenol glycosides from a substrate of starch and polyphenol-aglycone. We observed that the CGTase derived from culture filtrate of some microbial strains (Candida rugosa, Bacillus megaterium, B. coagulans and B. polymixa) could synthesize transfer products in the presence of appropriate polyphenol-aglycones as their acceptors. An inhibitory effects of enzymatically synthesized polyphenol glycosides against bacterial growth was furthermore examined. It was found that polyphenol-glycoside, as one of the transfer products, exhibited high antibacterial activity on the growth of Bacillus subtilis and Escherichia coli, no effect when on Bacillus cereus.Key words : Cyclodextrin glucano transferase (CGTase), enzymatic transglycosylation,polyphenol glycoside, antibacterial activity.
