Abstract

Asteraceae is one of the largest families in the Angiosperm. It comprises of 24,000‒30,000 species which are grouped into 1,600‒1,700 genera and distributed in a cosmopolitan range. Based on Backer and Bakhuizen van den Brink’s 1965 works, they identified 227 species of Asteraceae in Java. Many of them are introduced species, both cultivated or naturalized. However, the cultivated species have not been recorded. The aim of this study is to provide information about new records of cultivated Asteraceae in Java. The observations were carried out in Bandung, Bogor, and Sumedang, during January to February 2019. Nine additional species were discovered; species belonging to genera Caputia (two species), Curio (two species), Kleinia (one species), Gymnanthemum (one species), Senecio (two species), and Tarlmounia (one species). These species were grouped into two tribes: Vernonieae and Senecioneae. This study indicates that information on Asteraceae of Java need to be updated.

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

Common carp (Cyprinus carpio) cultivation is often hampered by a disease attack, one of them is the attack of Edwarsiella tarda. Lactic acid bacteria (LAB) can be used as an alternative to prevent diseases in fish by increasing the body's resistance. This research aimed to determine the most effective isolates of LAB that increase of the resistance of carp fingerlings to the attack of E. tarda bacteria and see which isolates can produce the highest survival. The LAB isolates used were the result of isolation from the gut of carp. This study used a Completely Randomized Design (CRD) consisting of four treatments with three replications. The fish were immersed with different LAB isolates, CcB7, CcB8, and CcB15 in the same density of 108 cells / mm3. Immersion was carried out for 30 minutes with a frequency of seven days. While during the research, two immersions were carried out before the challenge test against E. tarda bacteria. The parameters observed were the number of leukocytes, hematocrit, erythrocyte, differential leukocytes, survival rate, and clinical symptoms that appeared. The results showed that all LAB isolates used in this study could increase the body resistance of carp against the attacks of E. tarda bacteria. The LAB CcB7 isolate was the most effective for enhancing the body resistance of carp fish withthe highest increase level of  leukocyte, erythrocyte, and hematocrit were 18 ± 0.057,7 ± 0,077, and 0.26± 7.31% respectively. After being challenged with E. tarda bacteria producing mild clinical symptoms, the highest increase is in monocyte and neutrophil cells was 20 and 62% respectively, the highest reduction in lymphocytes was – 9%  and the highest survival rate was 80%.

Abstract

The use of bacteria as a biological control agent in aquaculture is such new hope overcoming the negative impacts of the impropriate use of antibiotics. Bacillus is widely known as a potential probiotic for aquaculture, especially which are derived from aquatic biota. Due to a concern that the role of Bacillus as a probiotic agent will be disrupted by residues of antibiotics in the water, this research aimed to identify Bacillus species from common carp intestine based on the molecular method and investigate their resistance to some com-mercial antibiotics that widely used in aquaculture. Chloramphenicol, ampicillin, and metronidazole were used to determine the Bacillus resistance to antibiotics using the Kirby Bauer method. The resistance assay was carried out with a bacterial density of 108 CFU/mL. The results showed that Bacillus isolates derived from common carp  intestine were closely related and resistant to antibiotics. Isolates that resistant to the three types of antibiotics were Cc.1.9 (CgN9) and Cc.2.18 (CgM18).

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%).
