Abstract

SRI PARYANTI WALUYO & DARJONO. 1986. Consumption and egg production of Kedu Fowl.Berita Bioiogi 3(4): 181 - 184. Four females and three males of Kedu Fowl has been subjected to an observation on egg production and consumption. The fowl was reared in individual cage for 68 days during the laying period.The observation revealed that the female consumed feed and water on an average of 94.645 gr and 254.45 ml a day respectively while the male was on an average of 105.96 gr and 294.91 ml a day.The manuvre production by the female fowl was recorded 85.81 gr per day. During the period of observation the average egg lay.ed by the female fowl was 34 eggs.In this period, the average weigt body gain on the female was 233.33 gr and on the male 41.66 gr respectively.In respect to the efficiency or raising Kedu fowl,feed and water in take.bodygain and egg production are considered important. These parameters are suggested to be applied as a basic selection of Kedu in a cage.

Abstract

Habitat loss and fragmentation are among the largest threats to herpetofauna diversity in tropical rain forest areas, including the rain forest in Kerinci Seblat National Park (KSNP). To measure the rate of negative impact to the herpetofauna population,fifteen survey sites with several degree of habitat disturbance were selected. Based on cluster analysis,15 survey sites were grouped into five distinct clusters, included low elevation forest group, high elevation group, swamp group, disturbed forest group and cultivated land group. Calculation of linier regression for four major (low elevation forest group, high elevation group, disturbed forest group and cultivated land group groups) showed that the rate of locally biodiversity losses were high (R2 > 0.7).

Abstract

A Thirty one species of macro fungi which belong to phylum Basidiomycota and Ascomycota were found from three villages in Enggano Island. Among those, nine species are new records for Sumatera, namely Phellinus gilvus, Fomitella supina, Flaviporus liebmannii, Coriolopsis polyzona, Flabellophora sp., Trichaptum byssogenum, Stecherrinum sp., Stereum cf. pergameneum dan Trametes cf. villosa, whilst other two species, namely Cookeina cremeirosea and Fomitella supina are new for Indonesia. One species, Phellinus gilvus, has been known as a harmful parasite on rubber plantation. Six are recognized as edible mushrooms, namely Pleurotus ostreatus, Volvariella volvacea, Schizophyllum commune, Auricularia auricula-judae, Lentinus sajor-caju, and Panus neostrigosus. Two species, Favolus grammocephalus and Panus neostrigosus are therapeutic agents, and two others, Earliella scabrosa and Pycnoporus sanguineus are potential species as color degradation agents.

Abstract

Kelimpahan jenis pohon eboni di kawasan hutan alam menurun sebagai akibat eksploitasi dan pemanfaatan secara komersial. Kayu eboni dimanfaatkan masyarakat sebagai bahan baku kerajinan tangan, mebel dan bahan bangunan sebagai mata pencaharian tambahan.Untuk mencegah penurunan kelimpahan yang dapat mengarah pada kepunahan jenis tanpa menghilangkan mata pencaharian masyarakat, perlu dilakukan suatu cara pemanfaatan yang berkelanjutan dari jenis-jenis eboni tersebut seperti pembangunan hutan rakyat dan hutan kemasyarakatan.Diusulkan suatu cara pengelolaan yang berkelanjutan baik dengan cara pelestanan in-situ, ex-situ, dan dengan teknik budidayanya. Diharapkan melalui pengembangan hutan tanaman, eboni dapat terus dipanen tanpa penurunan populasi di hutan alam.

Abstract

The study on cases of abortion in cow caused by fungi have never been reported so far in Indonesia. The aim of this research is to get prevalence of cows have not and have aborted, both have reproductive disorder, and health cattles associated with percentage of fungi isolated.The study included both field survey and laboratory examination of samples. The samples of vaginal fluid were collected by using cotton swabs in cow which had suffered abortion or cow had repeated breeding, as well as freeze dried semen for artificial insemination (AI), and also examining the occurrence of abortion in cattle. The samples were collected in Sukabumi and Bandung, and then cultured in Sabouraud Dextrose Agar by stretch method, followed by incubation at 37oC. Number of samples collected consisted of 56 samples of cattle which had suffered from abortion and cow that had reproductive problems; 38 samples as control; five samples of freeze dried semen. There were no cases of abortion observed when field survey was conducted, therefore organ samples were not available for pathological and histophathological examination. Further examination on growth rate of yeast showed 20% of yeast presented in cows with abortion, 17% in cows with reproductive problem and 14% in normal cattle. On the other hand,there were samples that did not show any growth of yeast recorded f rom cows with abortion (15%)cattle with reproductive problem (7%) and normal cows (27%). Meanwhile, only twowith 2 yeast growth observed in semen samples. It was concluded that samples from cattles with reproductive problems (with and without aborted experiences) showed higher number of growth of yeasts compared with normal cow (P<0,05). Freeze dried semen were having risk of contamination by yeasts. There was no different on growth rate of fungi between reproductive problem and with abortion cow (P>0,05).

Abstract

Sixty eight endophytic bacteria were isolated from four different rice varieties (IR64, Cirata, Code and Limboto) obtained from agroecosystem in Cikembar, Sukabumi, West Java. Those isolates were subjected for analysis the diversity based on genetic fingerprinting through Amplified Ribosomal DNA Restriction Analysis (ARDRA) method. The objective of this research is to characterize the predominant endophyte bacteria are present within various rice varieties grown on agroecosystem in Cikembar, Sukabumi by using ARDRA method. The results shows that restriction analysis with both Rsal and HaelH was sufficient to allocate the endophyte bacteria from four different rice varieties into the 29 types. Moreover, Rsal alone was capable of resolving the 11 types, followed by HaelH 14 types. In general, the result may explain that there is no collinierity between the cluster and their host plant. Staphylococcus, Bacillus, Agrobacterium, Serratia, Klebsiella, Acidovorax and Pseudomonas were identified as endophytic bacteria from rice varieties in this agroecosystem based on their 16S rRNA sequences. Seven types were placed in close proximity to these genera, but other types were still unknown. Among these isolates, genera Staphylococcus and Bacillus are common to rice endophytes.

Abstract

Fungal endophytes have been known as sources for bioactives with high chemical structure variability. This study aimed to screen extracts of some endophytic fungi associated with plants from Enggano Island as antioxidant and antibacterial using thin layer chromatography (TLC) bioautography method. Antibacterial ativity was performed against Escherichia coli and Staphylococcus aureus. Seventeen out of 22 extracts showed growth inhibition activity against both bacteria, while 16 extracts were active as DPPH free radical scavenging agents. Further determination on IC50 value of four prominent extracts revealed that fungal endophytes AK3018-1, FC-1, KC-4, and SO-3 have IC50 value of 85, 84, 704, and 347 ?g/ml, respectively in DPPH radical scavenging method. Extracts of fungal endophytes CR-3, CS-2, and SM-2 showed prominent antibacterial activity among other extracts, indicated by wide clear white zone around the spot. Further evaluation on minimum inhibitory concentration (MIC) of those three extracts by microdilution method showed that CR-3, CS-2, and SM-2 have MICs value of 512, >512, and 64µg/ml, respectively against S. aureus.Fungal endophytes AK3018-1, FC-1, KC-4, SO-3, CR-3, CS-2, and SM-2 were respectively isolated from Dioscorea bulbifera tuber, Fibraurea chloroleuca twig, Knema cinerea twig, Smilax odoratissima stem, Cryptocarya sp. twig, Calophyllum soulattri twig, and Smilaxmacrophylla stem.
