Abstract

Cempirit [Ervatamia svhaerocarva Burck.(Apocynaceae)] is a sticky plant found in Indonesia. This species had long been used as traditional medicine for skin diseases and ulceration of nose.Major biologically active compound was isolated from bark of E.sphaerocarDa by using combination of chromatography techniques (Thin Layer Chromatography,Colum Chromatography and High Performance Liquid Chromatography).The structure of this compound was elucidated by spectroscopic methods, mainly by NMR (Nuclear Magnetic Resonance) spectral. This compound was determined as indole alkaloide called Tabernaemontanine.

Abstract

Shoot cultures of Kaempferia rotunda L.were established from rhizome segment.In the 1st experimen these explants were planted on Gamborg/B5 medium that supplemented with BA concentrations were (0, 0.5, 1 and 2) mg/l and/or kinetine were (0, 2 and 4) mg/l.In 2nd experiment these explants planted in Murashige and Skoog medium (MS).This medium supplemented with BA concentrations (0, 2 and 4) mg/l and/or NAA (0 and 1) mg/l.The result in the 1st experiment showed that the best proliferated shoots was from the culture that supplemented with BA 1 mg/l and kinetine 4 mg/l, while in the 2nd experiment the best proliferated shoots was from the culture that supplemented with BA 4 mg/l and NAA 1 mg/l.These shoots were then subcultured on MS liquid medium supplemented with BA (5 mg/l) and MS agar medium was supplemented with BA (2 mg/l) + 2iP (0.5 mg/l) + thidiazuron (0.01 mg/l) + NAA (0.5 mg/l).The cultures could induce the shoots number and produce the morphological plantlets for acclimatization,and acclimatization successed on soil and compost mixed medium in ratio 1:1.

Abstract

Study on the comparison between allantoin (5 ¢ ureidohydantoin) and Betadine ® (povidone iodine) was conducted to compare and evaluate their efficacy, especially to accelerate wound (incision) healing. Treatment divided into three groups, first group is Control (without therapy), second group is allantoin treatment and the last one is Betadine ® treatment. Allantoin obtained from cattle's urine by Meissner method. The solution made of 2,4 grams of allantoin in 600 milliliters aqueous solution. Treatments (therapies) were given three times a day topically. Results showed no significant difference between allantoin and Betadine ® treatments (p > 0,05), control and the other treatments i.e allantoin and Betadine ® therapies have significantly difference (p < 0,01).

Abstract

Examination of morphological variation on Maxomys surifer from Sumatra, Jawa and Kalimantan were conducted using 60 adult specimens.Univariate and multivariate statistical analyses of 20 skull and four external characters showed that Maxomys surifer was not sexually dimorphic (P >0.05). The discriminant analysis based on skull characters indicated that Sumatran population had two distinct group; north (Ketambe and Tapanuli) and South to Central Sumatra, the north of Sumatra form was closer to Kalimantan and Jawa.

Abstract

A study on characteristic of genetic of the Timor deer (Cervus timorensis timorensis)was conducted during the periode of June - November 1997.Twenty four blood samples from Timor, Semau, Pantar, and Alor Island,Nusa Tenggara Timur Province were examined for this study.Restriction site analysis of part of ribosomeRNA mitochondrial DNA (447 bp),using restriction endonucleasis Haelll and Mbol showed that there were two haplotype variation.

Abstract

Two strains of fungi were used as innculant to produce Single Cell Protein (SCP) using the ganyong (Canna edulis Kerr.)starch as carbohydrate sources. Those two strains were Aspereillus nieer and A.clavatus identified as amylolytic fungi wich produce hight clear zone to colony diameter ratio in medium containing soluble starch with Iodium test.At the suitable interval time (0, 24, 48, 72 and 96 hours) the dry cell weight or biomass, pH and reducing sugar concentration in the medium containing ganyong starch was determined.It was found that maximum amount of reducing sugar concentration was hisher in A. clavatus (8.5 e/l) compared to A. nieer (4,5 g/l), were produced after 24 hours.The maximum amount of biomass produced by A. nieer was 8,5 g/l after 48 hr, while by A clavatus was 7,25g/l after 96 hr.

Abstract

Tamarind as tropical plant that grow well in dry land area and savannah. The use of tamarind product have been known as raw material for spices, drinks industries, and medicine, so that this plant is assumed very important for community in dry land area.In Besipae Savannah,South Amanuban,East Nusa Tenggara, tamarind grow wild in savannah and it is one of the sources income forpoeple in that area. During the dry season savannah produce less of fresh forages therefore the fresh leaves of tamarind are used as fodder.The function of cow dung as seed access especially as tamarind, acacias and leucaena seeds were not accomplished yet.The objectives of this study was the viability of tamarind seeds which were collected from cowdung in Besipae Savannah,South Amanuban, East Nusa Tenggara. This study was designed according to factorial model in Completely Rendomized Design(CRD), with four replications.The result of this study indicated that tamarind seeds which were collected from cowdung have higher germinatioan rate and percentage of germination compare to pure seeds from pods.Seedling growth of tamarind seeds which were collected from cowdung were better than that of seedling growth of pure tamarind seeds from pods. Application of cowdung and Bobonaro clay for germination media showed that Bobonaro clay was better than that of cowdung.

Abstract

Analysis of genetic variance, heritability and coefficient of genetic variance were carried out for seven characters of soybean mutant lines in M3 generation, which were conducted at CAIR-Field Station, Pasar Jumat, Jakarta.Results showed that the highest of heritability value about 85.50% was obtained for seed weight, and followed by number of pods,biomass of stem and shelpedpods, root/stem ratio, seed weight/ Zpods ratio, and the lowest heritability value was biomass of root around 26,83% Analysis of coefficient of genetic variance from seven characters of soybean mutants indicated value ranging from 10.00-39,50%.From the result of experiment can be concluded that gamma irradiation produced high genetic variability in M3 generation and contributed positively for crops improvement through breeding programme
