Abstract

The microbial transformation of 2E-6E-farnesol by the endophytic yeast CA1C-4 isolated from temu hitam (Curcuma aeruginosa Roxb.) has been investigated. Incubation of the 2E-6E-farnesol in cultivated endophytic yeast CA1C-4 in PDB at room temperature (25–32o C) under shaking condition at 120 rpm for eight days, produce a biotransformed product. Chemical structure elucidation based on 1H- and 13C-NMR analysis and comparison with published data showed that the biotransformed product is 2E,6E-3,7,11-trimethyl-2,6,10-dodecatrien-1-carboxilic acid.

Abstract

Forest in Mount Salak area has a very important existence, so that in the year of 2003 was announced officially as a conservation area and became a part of Mount Halimun Salak National Park (TNGHS). As one of the conservation area in Indonesia, Mount Salak forest has so many natural resources which support the living prosperity of the people, especially The West Java citizen. But in the use of the natural resources people have never been appreciating the conservation concepts then causing the forest degradation rapidly and terribly saddening. In order to explore the vegetation in the conservation area left, then the ecology analysis was done by making research plots in a hectare area. Data collecting was done on the systematically-located 1 meter square-size sub-plots. Those plots were located in a relatively-good natural forest. Data analysis result stated Athyrium dilalatum, Stenochlaena palustris, Calamus javensis, Curculigo latifolia and Strobilanthes blumei were the species which dominated Mount Salak National Park in the altitude of 1.267 meter above sea level.

Abstract

Road corridor has been known to have an influence on the microclimate and vegetation condition along the forest edge which directly bordered with the road. This study was conducted in order to obtain information regarding the depth of edge influence which can be seen by the changes in microclimate and vegetation condition from forest edge to interior in Pohen Mountain, Batukahu Nature Reserve Bali. Microclimate variables such as light intensity, wind velocity, temperature and relative humidity, and vegetation variables such as basal area, tree height, density and number of species were measured on two 100 m transects perpendicular from forest edge to interior. The correlation between microclimate and vegetation condition with distance from the road was analyzed by using MANOVA and ANOVA. The depth of edge influence was estimated by using Principal Component Analysis (PCA) ordination. Microclimate showed significant correlation with distance from the road to forest interior (r > 0.5, p < 0.05). Light intensity, temperature and wind velocity tends to decline as we move towards the forest interior and the reverse was true for the relative humidity. Microclimate gradient changed sharply until it reached the distance of 40 m from the forest edge. For vegetation parameter only the height of trees which was signifi cantly correlated with the distance from the road. PCA analysis showed that the depth of edge influence for the microclimate condition was clearly showed up until 40 m from the road. This result suggests that forest buffer area with minimum width of 40 m is needed to protect the forest interior of Pohen Mountain from the exposed microclimatic condition of the edge area.

Abstract

This research investigate the population and potentials denitrification activity from three different soils, organically farmed soil, intensive farmed soil and forest soil. Our objectives were to explore spatial gradients in denitrifier populations, examine whether populations density and its potential activity was related to soil chemical properties (C and N content), and determine the potential emission of gas N2O. Results indicated biological functional differences between these three different soil ecosystems. Forest soil had the highest population density of denitrifying bacteria and also had significant potential denitrifying activities. The highest potentials denitrifying activity in the soil affected to the lowest emission of N2O gas. The lowest population and potential denitrifying activity was measured in the intensive farmed soil. Those conditions might be promoted the potentials emission of N2O.

Abstract

Hypervariable II (HVII) regions of mitochondrial DNA (mtDNA) D-loop regions of Macaca nigra lived in Tangkoko and Dua Saudara National Parks have been analysed. An approximately 600 base pairs (bp) of HVII regions was sequenced to characterize genetic variation among 20 samples of Macaca nigra lived in Tangkoko and Dua Saudara National Parks. Using an outgroup of Macaca fascicularis of Kalimantan, a neighbor-joining and maximum parsimony trees both identified that all DNA samples of Macaca nigra were arranged in similar cluster. The low nucleotide diversity among samples of Macaca nigra in Tangkoko and Dua Saudara suggests either there is a direct mix among species or that they may have similar ancestor among them.

Abstract

Soil pollution has been so attracting considerable public attentions over the last decades. Phytoremediation is an emerging technology that uses plants to clean up pollutant soils. The study was carried out in gold mining Cikotok, Banten. Sengon buto (Enterolobium cyclocarpum, (Willd) which is used as cyanogenic plant, compost and microbes inoculant is as stimulator to growth this plant. The experiment consist of K0 as control (plant without compost), K1 as plant + compost and K2 as plant+compost + microbe inoculant, with 3 replicated. The objectives of this experiment were to investigate the potential for phytoremediation of cyanide contaminated soils using hyperaccumulator/cyanogenic plants and to assess the fate and transport of cyanide compounds in soils. The results showed that compost and microbe were able to stimulate growth of Sengon Buto after 7 months planting and to reduce cyanide until 66% Total bacteria in the study was relatively stable but NFB bacteria was decline.

Abstract

Insects are a very important role in an ecosystem. Among these roles are: herbivori, predation, parasitism, decomposition, pollination, and so on (Speight et al., 1999). In addition to the role of insects have been used as an indicator species. Several recent studies (Davids, 2000; Talvi, 2000; Castillo and Wagner, 2002; McGeoch, 1998 & 2002) shows that insects have a response that indicates the extent of damage to forest habitat. To see how much effect the change will see the diversity of insects flying at both locations using the window trap. This method was chosen because it will look at the role of flying insects that can be used as indicators of changes in land to the stratification of the existing trees at both locations. The expected goal in this study were 1) To determine the level of insect diversity in both forest site 2) To determine the effect of changes in forest insect conditions in each forest stratification. From this research it was found that it contained the highest density of heterogeneous forests there are 29 families of 41 species and 119 individuals from arrest (day and night) while in monoculture forests with 32 species of 22 families and 98 individuals in which the degree of diversity between the forest with a monoculture in the heterogeneous forest monoculture forests range 2.14 <H <2.84. Whereas in heterogeneous forests ranges between 2 <H <3 and the third similarity index was not significantly different strata.

Abstract

White mushroom is one of popular food commodity in East Java. Every year total production of white mushroom is more than 4800 ton. The cultivation of this mushroom needed the medium known as "baglog". Every 3 month the medium should be changed. The huge amount of solid waste will be produced around 40 tons/month and must be managed by farmer. Based on the composition of waste contains 80% of sawdust and 10% of rice brain. This composition known has a high concentration of carbon and potential as a material to produce of energy. This research investigated the effectiveness of "baglog" from medium of white mushroom cultivation as a briquette for energy alternative. Different variables used in this experiment are drying process and material that used as an adhesive for making of the briquette. The quality of the briquette such as energy value, compressive strength of briquette, moisture, fixed carbon and emission of briquette, was analyzed, based on Indonesia Standard. Result of the experiment showed that energy value of the briquette is 3400 cal/gram with drying process using oven. The compressive strength result showed that the adhesive using starch glue is very effective. This briquette is environmentally friendly

Abstract

Use of the yeast for cell based method to do a screening substances having anti-oxidant property is considered to be simpler and cheaper. In order to develop yeast Candida tropicalis as a tool for evaluation of anti- or pro-oxidant property of substances in cell level, toxicity of an analgesic drug acetaminophen in the yeast had been preliminary studied. Incubation of yeast cell suspension in presence of 0.3% acetaminophen for 2 hours significantly decreased cell viability. Malon dialdehyde, a biochemical marker for cell oxidative damage, increased. Acetaminophen of 0.1% or 0.039% decreased when added in cell yeast suspension or supernatant respectively for 1 hour indicating drug metabolism by cellular and extracellular enzymes. The data indicated that toxicity of the drug in the yeast could be compared to that in mammalian cell where the drug was metabolized by cytochrome P-450 or peroxidase and followed with oxidative stress in cells caused by metabolite byproduct. Toxicity of the drug in the yeast may be in relation with formation of reactive oxygen species. These preliminary data used the yeast for screening antioxidant property of substances against acetaminophen toxicity.
