Abstract

 Application of biocontrol agent is an environmental-ly-friendly method to overcome the Fusarium wilt in chilli due to Fusarium oxysporum. This research aimed to isolate actinomycetes antagonist to F. oxysporum FU3 as biocontrol agent from the soil of chilli plantation in Kulon Progo, Yogyakarta. The actinomycetes were isolated using SCA medium and followed by screening for anti-F. oxysporum FU3 on PDA. The filtrate from isolates which showing the highest inhibition zone was produced and tested against strain FU3. The best isolate was then characterized. There are four iso-lates of actinomycetes showing antagonistic activity against F. ox-ysporum (AK4, AK5, AK7, and AK9). The highest antagonistic ac-tivity was shown by AK5 filtrate with inhibitions on PDA and PDB are 41.71 ± 3.5 % and 81.77 ± 5.1 %, respectively. Further obser-vation showed that filtrate of AK5 caused abnormality and lysis on FU3 hyphae. From the results, we concluded that AK5 is a poten-tial biocontrol agent against F. oxysporum. Further studies to opti-mize the production and formulize the bio-fungicide are suggested

Abstract

 The aims of this study were to carry out testing of the early 4 protein of type 16 HPV through immunoinformatics meth-ods in an effort to get the peptide vaccine candidate for cervical cancer. The software used are IEDB-AR, CABSdock and Accelrys Discovery Study 4.5. Based on the analysis that sequence of ami-no acid lysine, leucine, leucine, glycine, serine, threonine, tryp-tophan, proline and threonine (KLLGSTWPT) and the sequence of amino acid tyrosine, tyrosine, valine, leucine, histidine, leucine, cysteine, leucine, alanine, alanine, threonine, lysine, tyrosine, pro-line and leucine (YYVLHLCLAATKYPL) are peptide vaccine can-didate for cervical cancer from the early 4 protein of HPV type 16

Abstract

 Giant forest ant Dinomyrmex gigas is one of the largest ants species in the world, native to the rain forests of Southeast Asia. It is known that ants have glands that produce chemical compounds that inhibit the growth of microbes. Therefore, it is necessary to deter-mine the antioxidant and antibacterial activities as well as identify the chemical compounds of D. gigas extract. D. gigas was extracted successively with n-hexane, ethanol and methanol. The antioxidant activity was evaluated by determination of the half-maximal inhibi-tory concentration (IC50) values while the antibacterial activities of the extracts were determined by measuring the minimum inhibitory concentration (MIC). The results exhibited that the IC50 values of n-hexane, ethanolic and methanolic extracts were 336.18±0.0984, 89.16±0.0219 and 90.72±0.0894 μg/mL respectively. The ethanolic extract exhibited the highest AAI value (0.34) followed by metha-nolic extract (0.33) and n-hexane extract (0.09). Based on AAI val-ues, the extracts were classified as moderate antioxidants. The best MIC values were 625 μg/mL for both ethanolic and methanolic ex-tracts against S. aureus, while MIC values of all extracts against E. coli were >625 μg/mL. Based on MIC values, all of the extracts presented weak activity against both S. aureus and E.coli. The GC-MS analysis showed that there are up to 30 compounds construct-ed of the ethanolic extract. Three major compounds are ethyl oleate  (29.78%), n-hexadecanoic acid (17.54%) and oleic acid (10.65%).

Abstract

 Paphiopedilum javanicum (Reinw. ex Lindl.) Pfitzer known as slipper orchid is an endemic terrestrial orchid from Indonesia. This orchid is threatened with extinction and listed under CITES Appendix I. In-vitro propagation of P. javanicum has been done in Bali Botanic Garden (BBG) for last six years but acclimatization stage has not given satisfied result. The purpose of this study was to know the ef-fect of liquid fertilizer on vegetative growth of P. javanicum planlet during acclimatization stage. Beyonic StarTmik liquid fertilizer ap-plied by five different doses considered as treatment of 0, 10, 20, 30 and 40 mL. They were 10 planlets for each treatment considered as replication. In this research we observe vegetative growth of P. ja-vanicum by quantitative and qualitative parameter. Quantitative data were analysis by ANOVA. Result showed, high percentage of planlet survival was observed of 98% and liquid fertilizer dose for 30 mL gave the optimal vegetative growth of P. javanicum planlet with aver-age height of 2.2 cm and leaves number of 13 pieces. There were no differences on qualitative parameter in all treatment that all leaves color was dark green and leaves tessellation appearance was obvious

Abstract

 Environmental characteristics can influence the distribu-tion of animal communities including fish in aquatic habitats such as a river. The study of fish communities in Cisadea River aimed to learn the relation between the fish community structure and the environmental characteristics of the river itself. This research was conducted in Cisadea River, Cianjur Regency, West Java, Indone-sia during dry season from July 2012 until February 2013. Samples of fish were caught using active fishing gear (Electrofishing Gear, spreading nets, scoop, lift net) and passive fishing gear (trap). The results showed that the quality of the physical chemistry of Cisadea waters was still in the normal range that could support fish life. The fish community in Cisadea River consisted of 11 orders, 26 families, 35 genera and 48 species. During the study, Rhyacichthys aspro (19,85%) and Glyptothorax plathypogon (20,15%) were the domi-nant species caught. The diversity index value (H’) was 2.87 (mid-dle category) with the dominance value of 0.09 (low category) and evenness value of 0.74 (high category). Moreover, community simi-larities according to the presence of species made the LC1 and LC2 locations in one group while the LC3 locations in a separate group.
