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

 West Java Province has the largest population amongst others in Java, and therefore land conversion rate in the region is increasing. Approximately 40% of forest areas in West Java has been converted between 1990–2015. As a consequence, the number of bi­odiversity in the region is decreasing, including amphibians and rep­tiles. These groups play an important role in the food chain of an ecosystem, and are very sensitive to environmental changes. How­ever, comprehensive research on amphibian and reptile species in West Java is suboptimal. Visual Encounter Survey has performed in seven districts in West Java for one month and has recorded 26 amphibian species and 27 reptile species. These species were in­cluding Javan endemic species (for example: Fejervarya iskandari, Huia masonii, Limnonectes microdiscus, Megophrys montana, and Microhyla achatina), introduced species (Calotes versicolor), and species with a new distribution record (Leptophryne borbonica and Kalophrynus minusculus). In addition, cryptic species (Genus Lep­tophryne and Cyrtodactylus), which are interesting for further stud­ies, were observed. This study has demonstrated that the potential of a comprehensive study of amphibian and reptile species in West Java is great. Apart from this, conserving the biodiversity in the region also challenging due to the high rate in land conversion

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 growth of Pak Choy (Brassica rapa var. chinensis) using nutrients from catfish “Sangkuriang” (Clarias gariepinus) wastes was investigated in the household scale aquaponics systems by comparing the growth parameters value among the grow beds. The growth parameter of Pak Choy was fresh weight, leaf number, and leaf area. Meanwhile, catfish growth parameters were body weight and length, and feed conversion ratio (FCR). The experiments were arranged in a Completely Randomized Design (CRD) with 4 treatments and 3 replications. The data were analyzed using Analysis of Variance (Anova) followed by Duncan Multiple Range Test (DMRT) at 95% level of significant The result of the study showed that there were not significantly different in the growth parameter of Pak Choy among the grow beds in the vertical system. However, those in grow beds “Ä” were significantly higher than the rest of the grow beds in the horizontal aquaponics system. In general, all the growth parameter of Pak Choy in the vertical system was higher than in the horizontal one, although, it was not statistically significantly different. Nevertheless, the horizontal aquaponics system gave better results in the body weight and FCR of catfish.

Abstract

Polyurethane is a class of polymers characterized by their substantial tensile strength and high melting points which enables them to be extremely durable. Despite its xenobiotic origin, polyure-thane has been found susceptible to biodegradation by microorgan-isms. The main object of this research was to investigate polyurethane degradation by the bacterium isolated from decayed teak wood (Tec-tona grandis Linn. f.). Polyurethane degrading bacteria were isolated using selective medium in the form of LB (Luria Bertani) with the ad-dition of 0.3% Impranil. Bacterial biodegradation activities shown by the changes of polyurethane structure analyzed by FT-IR spectrosco-py. The bacterial identification was carried out based on observations on the morphological characteristics of the colonies, cell morphology and sequences of 16S rRNA encoding genes. One of the potential iso-late that successfully isolated was K9, which demonstrates the disap-pearance of the 1735/cm peak of the characteristic function urethane in the FT-IR analysis. Analysis of the 16S rRNA encoding gene showed that the potential isolate having 98% similarity index to Bacillus safen-sis strain FO-36b. The activity shown by the isolate suggests that the bacteria could be a promising agent for polyurethane degradation.

Abstract

Bukit Tiga Puluh National park (TNBT) of Riau Province is a nature conservation area with a high diversity of fauna, one of which is the butterfly. Butterfly species diversity is influenced by the vegetation in their habitat. The TNBT utilization zone has a habitat type with varied vegetation. There is no information about the species of butterflies in the area. This study aimed to identify morphological character of butterflies and vegetation based on morphological characters. The method used was exploration. The catching area of the butterfly was the Granite waterfall and the Bukit Lancang path of TNBT utilization zone. Samples made as insectarium and herbarium. The  identification of butterfly characters consisted of the head, thorax, abdomen, legs and wings. There were a number of different types of butterflies and plants between the Granite waterfall area (22 and 28 species) and the Bukit Lancang paths (5 and 9 species). The type of butterfly was dominated by the family Nymphalidae. This is due to the amount of vegetation and environmental conditions that are more favorable in the granite waterfall area. The key determinants of butterfly species are the characters of the wing. The results of this study can contribute to maintaining the TNBT butterflies in Riau Province and also as database information of butterflies species in Indonesia.

Abstract

Marine ornamental trade has been developing for several years with Indonesia as one of the major exporter countries. Among the popular marine ornamental fish in the local and international markets belong to the family of Chaetodontidae. The existence of this family has been reported from several areas in Indonesia. However, no information is available in terms of their phylogenetic relationships of the fish from the south coast of West Java. The aim of this research was to asses the phylogenetic relationships among ornamental fish members of Chaetodontidae in the South Coast of West Java. Fish samples were collected from two trading sites Ujung Genteng and Taman Manalusu. Collected fish were identified using a previously published study. The evolutionary relationships among species were analyzed statistically through phylogenetic analysis based on maximum parsimony algorithm and Kimura 2- Parameter substitution model as implemented in PAUP 4.0 software. Tree branching pattern supported by 1000 bootstraps pseudo-replicates and out-group comparison. Daschyllus trimaculatus used as outgroup species. Based on the study, Chaetodontidae from the South Coast of West Java formed one monophyletic group compared to Dascylus trimaculatus with Chelmon rostratus was the basal species. All the remaining species were the derived species. There are CI and RI value gained. The consistency index (CI) value of this family is 0.5833, and the retention index (RI) is 0.5082.

Abstract

According to the Flora of Java, there is only one species of Evolvulus in Java, namely Evolvulus alsinoides. Since then, a second species was reported in 2017 from Universitas Indonesia, Depok, West Java, as an alien naturalized species. Some recent field studies have been conducted to provide updated taxonomic information of the genus on this island. The field observations were carried out in Banten, Jakarta, West Java, Jogjakarta, and East Java from March to December 2019. The herbarium studies were also conducted in Herbarium Bogoriense, Herbarium of Bogor Botanic Gardens, Herbarium Bandungense, and Herbarium of the Department of Biology, Universitas Indonesia. Our study reveals one newly recorded species of Evolvulus in Java already grown in cultivation, namely E. glomeratus Nees & Mart. subsp. grandiflorus (Parodi) Ooststr. Besides that, Evolvulus nummularius is now also reported to occur in other sites of West Java and extended to Central Java. An updated key to Evolvulus in Java, descriptions to both species, photographs, and brief discussions are provided.
