Abstract

Ranu Pani and Ranu Regulo (2,200 masl) are lakesin Bromo Tengger Semeru National Park (TN.BTS) by area 1 ha and 0.7 5ha. Lakes were used for tourism,agriculture, live stock and fishing spot. Civil and visitors  activities give an effect onwater quality. The study was conducted in February-June2011, the aim of study to determine the diversity of macrozoobenthos, to know the water quality by seen thebioindicators and physico-chemical factors. Samples were taken at each of the five observation stations by Ekman Dredge and by hand. Samples were identified and analyzed by Shannon – Winner diversity (H) and Simpson dominance(D) indices. The results of study in Ranupani were consisted by 93 of Bulimidae, 14 of Hirudidae, 22 of Glossiphoniidae, 1 of Syrphidae, 1 of Gomphidae, 1 of Gammaridae and 3 of Coanagrionidae The results in Ranuregulo  were consisted by50 of Coanagrionidae,5 of Asselidae and 5 of Aeshnidae. The diversity indices was higher in RanuPani (0,98) than Ranuregulo (0.57). The dominance in deces was lower in Ranu Pani (0.51) than Ranu Regulo (0.71). Water conditions based on bioindicator  in Ranu Pani were classified as medium polluted–polluted.Water conditions in Ranu Regulo were polluted. The condition both ofwatersbased onH was weight polluted. The analysis ofphysico-chemical factors (based on PP.No.82.year.2001 onWater Quality Standards) for measuringof pH, DO, BOD, COD, nitrate, TSS and  TDS showed that the watersin Ranu Pani and Ranu Regulo included to class II and III(except Hatstation IV Ranu Regulo included to class IV and TSS at station II, IV, V waters Ranu Pani feasible for classIII). The Phosphate analysis showed that both of waters included to class III.

Abstract

The  objective  of  this  research was  to  studi  ability  of Trichoderma sp. fungal antagonist on reduction leaf blight intensity disease and potato yield. The in vivo experiment was carried  out  at  potato  land  area  located  at  BALITSA in Cikole Sub District, Lembang  District and Bandung Regency. Completely  Randomized  Design  was  used  with  six treatment and five replicates. The treatment tested consist of control  (without pathogen fungal and antagonists fungus application too), control (with  pathogen fungal application and without antagonist fungal application), chemical fungicide application, antagonist fungal application 2 weeks before planting, application 1 week after planting and both application 2 weeks before and 1 week after planting. Result of  the  research  showed  that  application of antagonists fungal could decrease disease intensity and tended to improve crop potato yield. Research repeatment with more quantity pouring the antagonist was needed. These antagonist could be used as biological agents initials to control leaf blight disease.

Abstract

Water is important natural resources for people and spring is one of clean natural water resources in the village. Indonesia has high rain fall, but water availability varies spacially and temporally. The change of land cover or ecosystem in spring catchment area or surroundings decreases water catchment capacity. Therefore it is necessary to conduct a study of floor vegetation contribution on rain-water infiltration. This study aims to determine the structures and the roles of floor vegetation in regards of water infiltration at various degrees of slope. This study was carried out in two times, end of the dry season from June to October 2013 and end of wet season from March to June 2014. Floor vegetation data were obtained from 6 plots (1x1m2) in each growth forms and slopes. Water infiltration were analyzed using rain simulation method in 0.5x0.5m2 plot size. Results showed that there were 18 species of 5 families and 29 species of 10 families found during the dry and wet season respectively. Rainy season triggered grass and herbaceous (Poaceae and Asteraceae) plant density from 5 to 9 times, and also shrubs density from 3 to 6 times. Based on important value analysis at slope classes, Panicum repens (34.7%), Ischaemum sp. (34.2%), Elephantopus scaber (33.5%), and Desmodium triflorum (11.9%) are grasses and herbaceous dominated all slopes during both seasons. Boerhavia difussa, Chromolaena odorata, Flemingia macrophylla, and Mimosa pudica are shrubs dominated in all slopes, especially at the steep slopes for the last 3 shrubs.  The diversity index of the floor vegetation can be categorized low. Based on the rain simulation with average rate of 67.6 mLs-1, P. repens and M. pudica, can respectively withstand water runoff for 27s and 18s and had infiltration capacity of 83.2 % and 75.9 % in the steep slope, and E. Scaber can withstand water runoff for 15s and had infiltration capacity 71.6% in the gentle slope.

Abstract

Pleurotus ostreatus or white oyster mushroom had been produced commercially on an industrial scale as food and supplements. It is because of this oyster mushroom contained nutritions that were nutriceutical benefit. These fungi acted as anti-tumor, lower cholesterol and anti-oxidants. Based on the wealth of information on the nutritions and the many benefits of this white oyster mushroom, we run the research to obtain information related to the potent of oyster mushrooms in mice. So that white oyster mushroom can be used as a potent medicine to heal various diseases. The purpose of this study was to determine the potency of white oyster mushroom as nutrition growth in mice. This study began with the optimization of the white oyster flour making. Mice in dose of 100 mg / KgBW showed the highest body weight compared to other doses. In the body length parameter indicated that the treatment group with dose of 100 mg / KgBW gave an average body longest compared to other groups. This dose also rise the highest feed intake while the group with the least amount of feed intake was in dose of 200 mg / KgBW.
