Abstract

Lincat disease of temanggung tobacco could not be controlled effectively. One method of control which could be integrated with other measures is biological control. Bacillus is one of soil microorganisms which was not used widely as a biological control agent of plant disease. This report showed the results of the use of local isolates of Bacillus in controlling lincat disease of temanggung tobacco. As much as 91 isolates of Bacillus were directly tested in the field for their capability in suppressing lincat disease development. Six isolates, Ba-4, Ba-22, Ba-24, Ba-30, Ba-33, and Ba-41, could suppress lincat disease in the field. The result of in vitro test indicated that not all isolates which produced zone of inhibition in vitro could suppress disease development in the field. On the contrary, not all isolates which suppressed lincat disease in the field could inhibit the growth of pathogen in vitro. Isolate Ba-41, could suppressed lincat disease in the field and inhibited the growth of Meloidogyne incognita but not inhibited the growth of Ralstonia solanacearum.

Abstract

Sambung nyawa (Gynura procumbens) has many beneficial effects to human health, such as decreasing blood pressure, maintaining blood sugar level (hypoglycaemic), decreasing cholesterol, a remedy for kidney trouble, antibacterial and lessen the inflamation (antiinflamation). This research was undertaken to discover the potency of endophytic microbes from sambung nyawa as antimicrobial agents. The purpose of this research was to screen the endophytic bacteria and the endophytic fungi having antimicrobial activity, which were isolated from stems, leaves, roots and fruits of medical plants, sambung nyawa. The antimicrobial activity was determined by measuring the growth inhibition of pathogenic microbes i.e Candida albicans, Escherichia coli, Pseudomonas sp. and Bacillus subtilis. A total of 38 isolates of bacteria and 15 isolates of fungi were obtained from sambung nyawa. Analysis demonstrated that, 45% isolates of bacteria and 20% isolates of fungi exhibited inhibitory activity. Antimicrobial activity was found in 21% of the isolates that inhibited the growth of C. albicans, E. coli, Pseudomonas sp., and B. subtilis, whereas 24% of isolates had activity only against B. subtilis. Isolate of endophytic bacteria USN 1.1 and USN 2.3 showed the most significant of inhibition zone. The Inhibition zone of the isolate USN 1.1 to C. albicans, E. coli, Pseudomonas sp, and B. subtilis were 2.318 cm2, 0.969 cm2, 0.796 cm2, and 0.381 cm2, respectively. The Inhibition zone of the isolate USN 2.3 to C. albicans, E. coli, Pseudomonas sp., and B. subtilis were 3.01 cm2, 0.519 cm2, 0.588 cm2 and 0.83 cm2, respectively. These results indicated that endophytic bacteria and endophytic fungi could be a promising source for antimicrobial agents.

Abstract

Linear Alkylbenzene Sulfonate (LAS) concentration over 0.5 mg/L has toxic effect on organisms in river ecosystem. Some indigenous Pseudomonas strains on detergent polluted river have capacity to degraded LAS. The objective of the research was to study the effect of increasing of nitrogen (N) and phosphorus (P) concentration in minimum mineral medium on growth and LAS biodegradation potency of Pseudomonas strains using batch culture. The experiment was carried out by Randomized Block Design and three replications. Each three milliliter of strain starter contain 108 cell/ml was inoculated into 27 ml of each media formulation. Each culture was incubated aerobically at 30 oC on shaker incubator. Amount of bacteria cell and LAS residue concentration were observed on 0, 3rd, 6th, 9th and 12th day incubation. Data was analyzed using variance analyze and followed by Honesty Significance Difference test on 5% significance level. The result of the research showed that Pseudomonas putida FNCC071, Pseudomonas sp. strain R, and Pseudomonas sp. strain J was capable to degrade LAS about 89.0%, 87.0% and 80.0% respectively in 12 days incubation. The highest increasing of N and P concentration in media gives the highest potency of bacteria strains to degrade LAS (p > 0.05).

Abstract

The leptocephalus drift with sea currents and moving from spawning area into coastal area near mouth of Progo River. In the coastal area, leptocephalus metamorfosed into glass eel, after that glass eel migrated to river. The aims of this research were to estimate glass eels age and predict hatching dates. Glass eels sampled on new moon during Februari 2007–Mei 2009 at mouth of Progo River. Glass eel ages estimated using their otolith microstructure. Hatching dates predicted with back calculation of glass eels age. We collected 1.082 glass eels. The ages of glass eel at recruit ranged from 58 to 190 days, and divided into 5 age groups. Glass eels are migrated to river hatched on “new moon” from July to January. Glass eels are migrated to river during October–January hatched during July–October. Glass eels are migrated to river during February–Juny hatched during November – January.

Abstract

Rapid assessment on moth faunas with focus on macro-moths was conducted at Nusa Barong Nature Reserve. The aims of the study were to acquire information of macro-moth diversity and to access the composition of the species at this area by comparing data from Meru Betiri National Park, Sebangau National Park and Busang forest. The results showed that the number of species at Nusa Barong, Meru Betiri, Sebangau and Busang were 47, 75, 97 and 297, respectively. The diversity of macro-moth fauna based on William’s α index at Nusa Barong was the lowest as compared to Meru Betiri National Park, Sebangau National Park and Busang forest, which were 34.58, 65.01, 50.91 and 102.08, respectively. The results also show that the similarity based on Jaccard’s index of the binary comparison varies from 0.029 to 0.089. The highest value was the comparison between Nusa Barong and Meru Betiri while the lowest was the comparison between Nusa Barong and Sebangau. In addition, Pyralidae, Geometridae and Noctuidae were dominant across all sites. At Nusa Barong, only 10 species that have been known their host plants; three of them caused damage to some crops, namely, Conogethes punctiferalis, Cydalima laticostalis and Achaea janata. There might be more species that have not been found during this study as indicated by the species numbers across all sites have not reach a plateau. This study clearly showed us that floral diversity and size of area determined the diversity of macro-moths at Nusa Barong Nature Reserve.

Abstract

On April and September 2006, preliminary study to know the distribution, population status and habitat of the Javan moustached parakeets (Psittacula alexandri alexandri Linnaeus 1758) were conducted in the Baluran and Alas Purwo National Parks (East Java) and in the Tilu Geder Mountain Forests and in the Darmaga IPB Campus Parks (West Java). Direct and indirect observations were used in this research. The results are found only 2 individuals of birds in the Darmaga IPB Campus Parks. However, 45 species of plants were recorded as the natural food resources for the Javan moustached parakeets in the fields. Almost 60% parts of plants i.e., fruits were food by birds, even if those birds are more frugivorous. Some species of plants were known as the nesting trees for the species, namely: Tectona grandis, Acacia lecophloea, Azadirachta indica, Tetrameles nudiflora and Eucalyptus deglupta. The Javan moustached parakeets have needed mangrove forests, beach forests, evergreen forests and old teak forests for their activities. The population and their habitat of javan parakeets are threatened by forest fragmentation effects and over hunting.

Abstract

Typhoid fever is highly endemic in the South-West Sumba Regency, East Nusa Tenggara. The incidence rate of the diseases is high estimated at 725/100,000. It is an acute systemic infection caused by Salmonella typhi. The clinical symptoms of the disease are extremely diverse, starting from the mild form to severe ones with the most feared complication being perforation within the small intestine. Therefore, it is important to perform isolation, characterization, and grouping of S. typhi strains from the blood culture in order to determined definitely diagnosis and the different phenotypic characteristics in the community. Isolation was done in selective and differential media: BacT/ALERT FA culture media, Selenite Cystine Broth, Chromocult Coliform Agar, MacConkey Agar, and Salmonella Shigella Agar. The typical colony of Salmonella was confirmed on Triple Sugar Iron Agar, Urea agar, and L-Lysine decarboxylation media. Phenotypic characteristics of all isolates were identified using API 20E and API 50CHE diagnostics. Based on biochemical characteristics the result showed that 18 strains obtained from different geographical origins were diverse. Four strains have similarity value 100% while the remained strains have similarity value 86.3–98.4%. All of the strains were categorized in the species of S. typhi.
