Abstract

Pseudomonas aeruginosa is an opportunistic bacterium that causes infections in human. The wall cell of its bacteria contains lipopolysaccharide as virulency factors to protect it from human immunity. Lipopolysaccharide can inhibit phagocytosis in the body. Polysaccharide krestin (PSK) from Coriolus versicolor extract contains ?-glucan that can increase phagocytic activity and capacity. This research aimed to identify the effect on polysaccharide krestin from C. versicolor extract on phagocytic activity and capacity of mice exposed by P. aeruginosa. The design of this research was experimental design. There were six treatment groups. The phagocytic activity and capacity were counted on slide smears of mice peritoneal fluid. The data was analyzed by using one way ANOVA. The results of the phagocytic activity and capacity showed that PSK was added before exposure (P1) or after exposure (P2) or before-after exposure (P3) had potential to increase phagocytic activity and capacity. The conclusion of the research was that adding polysaccharide krestin either before exposure or after exposure or both of them could increase phagocytic activity and capacity. The benefits of this research to development of science are expected to reduce human infection and to utilize natural ingredients as immunomodulator.How to CiteWahyuningsih, S. P. A., Savira, N. I.

Abstract

The purpose of this study was to identify the selection criteria to obtain a superior mutant derived from the wheat plants of such varieties as Dewata, Selayar and Alibey, adaptive in medium land. The analysis of agronomic growth characters showed a significantly effect on a growth percentage of the initial growth (8 mutants), flowering time (1 mutant), panicle stem length (15 mutants), number of panicles (7 mutants), the number of grains per panicle (8 mutants), grain weight observed (8 mutants), grain weight per genotype (6 mutants), leaf area (2 mutants) and leaf greenness (5 mutants). The effects on the characters of ripe time, harvest, panicle length and plant height were not significant. The mutants of Dewata, Selayar and Alibey could be selected based on the characters of panicle stem length, number of grains per panicle and grain weight per observation because these characters generated more mutants than the other characters. The correlation analysis between the characters of growth and yield components of wheat mutants showed that the number of grains per panicle was positively correlated with the grain weight observed, while the length of panicle stem was positively correlated with grain weight per genotype, number of panicles and leaf area. Hopefully some mutants produced could adapt to the tropical medium land, thus adding to the diversity of wheat germplasm in Indonesia, thereby reducing the import of wheat to Indonesia.How to CiteSari, L., Purwito, A., Sopandie, D., Purnamaningsih, R. & Sudarmonowati, E.

Abstract

In this study, twenty local durian accessions obtained from Central Java in situ collection were characterized using the morphological characteristics and the restriction patterns which generated from the region spanning the internal transcribed spacers ITS LEU and ITS 4. Morphological characteristics of durian leaf, stem, tree, and fruit showed variations for the different accessions, whereas polymerase chain reaction (PCR) products of ribosomal DNA region showed a low length of variation. The size of the PCR products and the restriction analyses with the restriction endonucleases Bsp1431yielded a restriction pattern for each accessions. The results of this study can be utilized by local durian farmers as a preliminary reference for durian propagation. The data obtained need to be supported by further research using the other molecular markers to obtain more accurate data. The clear identity of durian species can help the management of propagation systems by farmers to get superior local durian.How to CiteFibriana, F., & Hadiyanti, L. N. (2016).

Abstract

Peat soil is a type of soil that dominates the island of Borneo. Typical compounds in peat soil is humic acid. Various in vitro studies performed have shown peat subtropical humic compounds can stimulate the immune system. However, in vivo study on animal has not been done. This study aimed to determine the effect of humic acid extracted from peat soil of Borneo against the immune system, both of non-specific and specific immunity Wistar rats (Rattus novergicus). Research using a completely randomized design with five treatments and five replicates, the normal controls, a positive control (isoprinosine), humic acid 125; 250; 500 mg/kg. Humic acid was administered orally for 10 days. The results showed humic acid adduction did not significantly affect levels of hemoglobin, erythrocytes and hematocrit. Humic acid adduction of 125 mg/kg significantly affects the total leukocyte count and differential leukocyte. Humic acid 125 mg/kg also showed increased phagocytic index better than normal controls. All humic acid treatments do not provide a significant effect on the total amount of antibody. The results of this study can be used for the development of Borneo tropical peat resources as natural imunostimulant.How to CiteRousdy, D. W., Rahmawati, R. & Kurniatuhadi, R. (2016).

Abstract

The leaves of Zingiberaceae family has not been much explored its potential, especially as a skin lightening. The relationship between total anthocyanins, chlorophyll, carotenoids and tannins contents of Zingiberaceae leaves and tyrosinase activity were determined. Ten species of Zingiberaceae were separated by n-hexane and the residues were extracted with ethyl acetate. The total anthocyanins, chlorophyll, carotenoids, tannins contents and the activities of ethyl acetate extracts were determined by spectrometric method. The tyrosinase inhibition was determined by using L-tyrosine (monophenolase) and L-DOPA (diphenolase) substrates. The most active extract was the leaves extract of Zingiber purpureum which exhibited 82.86% for monophenolase inhibition and the leaves extract of Curcuma zedoaria which exhibited 90.20% for diphenolase inhibition. The correlation between carotenoids content and monophenolase inhibition was 52%, while between tannin content and diphenolase inhibition was only 15%. Therefore, among 10 leaves species of Zingiberaceae, Zingiber purpureum Roscoe and Curcuma zedoaria leaves are the most potential for tyrosinase inhibitors and can be developed as whitening agent.How to CiteBatubara, I., Kartika, Y. & Darusman, L.

Abstract

Tropical rainforest changed in term of structure, composition and population, resulting from logging. One of target trees during logging is Pometia. Our goals of this research were to answer that (1) How were survival, growth, fecundity and population growth rate (?) of Pometia within remnant stands?; (2) what were driving factors to explain population dynamics of Pometia within logged forest?. Data were derived from three hectares-permanent sample plot (PSP) in logged forest of PT Tunas Timber Lestari. Integral Projection Models (IPMs) were applied to analyze population dynamics. The study showed dynamically that probability of the individuals of Pometia survived in this area did not significantly differ among their size, while stands showed the significant difference between small and large individuals. The growth of both individuals of Pometia and stands varied significantly in different size. The probability of fecundity both Pometia and stands were significantly different among size. The population of Pometia has been increasing for about a decade as the population of all stands was growing as well. Moreover, the regular documentation of species composition and structure before and after logging is necessary as a control of biodiversity. Therefore, a proper protocol to monitor the biodiversity should be designed by government and disseminated it to logging companies. How to CiteMurdjoko, A., Marsono, D., Sadono, R. & Hadisusanto, S.

Abstract

Mount Rinjani area on the island of Lombok is unique in bioecology. It provides habitats for many species of birds, especially birds of Wallacea. Several studies on birds in this area have been done, but the conservation priority of these birds has not been determined. Based on this condition, the purpose of this research is to determine the priority of birds conservation in mount Rinjani areas. Exploration about the spesies of birds was started from Senaru Village to Segara Anak Lake. Abundance of each bird species was estimated using point count. Data analysis to determine the conservation priority used indicators that consist of endemicity, population status, species threatened and species management. The results showed that the birds species in mount Rinjani areas are composed of 32 species belonging to 20 families. Bird species that have high abundance were Amandava amandava (15.94%), Zosterops Montanus (15.70%), and Parus major (11.32%), while Ptilinopus melanospila and Anthus novaeseelandiae were in low abundance (0.23%). Analysis birds conservation priority in mount Rinjani areas indicates that Otus jolandae has the highest score (65) and should be the first priority for the conservation, while Philemon buceroides and Gallus varius with the same score (60) are the second priority.
