Trichophyton mentagrophytes and Candida albicans Antifungal Activity of Palanjau (Pentaspadon metleyi) Wood ExtractivesPelanjau wood (P. motleyi) extractives traditionally used as medicine for skin infection such as scabies (tinea) and rash caused by fungal T. mentagrophytes and C. albicans. The aim of this research was to identify the effectiveness of pelanjau wood extractives on growth inhibitory of fungal T. mentagrophytes and C. albicans, isolate and identify extract compounds which have antifungal properties. Extraction and fractionation process yielded 7,04% of ethanol extract consisting of 0,28%, 1,28%, 1,19% and 4,29% of n-hexane, diethyl ether, ethyl acetate and residue fractions, respectively. Antifungal activity of pelanjau wood extract more effective on C. albicans growth inhibition than T. mentagrophytes fraction ethyl acetate at (0,03 and 0,06 mg/ml of MIC and MFC, respectively). Isolation of ethyl acetate fraction was resulted dominant compound EA6a and EA6c. NMR and GC MS analysis of compound EA6a indicate 2-Hidroxy octadecanoid acid, Hexadecanoic acid, Ethyl oleate, Octadecanoic acid, Vanilin and phenol,2-methoxy-4-(1-propenyl) as the possibly main component belonged to fatty acid and phenol group. Compound EA6c indicate Phenol, 4-(1,1 dimetylpropyl), Nonylphenol isomer, Phenol,4-(1,1,2,2-tetrametylbutyl), Nonyl-phenol mix isomer dan 4-Nonylphenol as the possibly main component in belong to phenol group.

A Study of Comfort for Activities in Urban Forest Landscape of UGM; Study Case: Agro Cluster UGMThe phenomenon of global warming has caused discomfort activity in urban area. Greening in open space of Gadjah Mada University campus has been developed as urban forest landscape that supporting good environment produced high comfort for activity and enhancing urban conservation. The research objectives were to observe the comfort for activity in urban forest landscape, to observe the canopy coverage of urban forest and to reveal the effect of tree canopy coverage to the comfort for activity. Data collection was carried out by visual observation, questioner, micro climate measurement, and hemispherical images of the tree canopy coverage. Data were analyzed by descriptive statistics. The tree canopy coverage was calculated by the Sky View Factor (SVF) of hemispherical images. Research results showed that activity types in the urban forest landscape were study (10%), sitting (37%), meeting (39%), others (14%) at spread of sitting areas. Some factors that affect the comfort for activity in urban forest landscape were aesthetic, lower temperature, fresh air, inspirited area, and listened bird voice. The respondents (82%) said that the urban forest landscape was comfort for activity at whole time of 07.00 - 17.00 by the condition of local climate presented by air temperature at 29.7 - 32.6°C, normal humidity at 61.5 -74.1% and breeze wind velocity at 0.6 - 2.8 m/s. Tree canopy of urban forest landscape had covered more than 50% identified by Sky View Factor (SVF 0.026-0.446). The tree canopy coverage of urban forest created tree shaded areas for the activities which showed thermally comfort because of microclimate controlled by urban forest.

Determination of the Competition Level for Growing Space of Teak Canopy from 11-year- old Progeny Test in KPH NgawiThe increasing demand of teak wood should be followed by the increasing of teak forest productivity through intensive silviculture, especially growing space manipulation. The main objective of this research was to determine the growing space competition.The material was measurement data from eleven year progeny test located at the compartment 49a, RPH Sidowayah, BKPH Kedunggalar, KPH Ngawi. The growing space competition was calculated using Hegyi’s competition index. Superior trees were selected to determine competition zone of the subject tree and this result was proposed to calculate the competition index of all trees. Based on the correlation between competition index and tree height, vertical structure was then classified using k-means cluster.Based on 300 superior trees, the competition zone could be determined using reference angle of 66°. The competition index was vary in between 0.00 and 4.23 with average value of 1.18. The correlation between the index and the tree height was found to be low with r = -0.227. Based on this correlation, the vertical structure was classified into four level namely dominant, co-dominant, medium, and suppressed respectively.

Grafting Success Story of Teak (Tectona grandis L.f.) from Exploration Material in Gunung KidulTeak exploration as planting material source of superior genotype is necessary for hedge orchard establishment for forest communities in order to produce the planting material by themselves. The objective of this study is to identify the success and growth of teak grafting resulted from exploration in Gunung Kidul region.The exploration aimed to collect teak ortet (mother tree). The ortets would be used as materials for hedge orchard, as the cutting source for community forest plantation. The study was conducted in Gunung Kidul region (for exploration) and in the Laboratorium on Intensive Silviculture, Silviculture Department, Faculty of Forestry UGM. In the laboratory, the first three months was to examine grafting compatibility, and the second three months to monitor the growth of teak grafting. The experiment in the laboratory was performed with Completely Randomized Design (CRD), with treatment of 16 clones and 10 treeplot replication each, making total of 160 clones.The study resulted in the following: 1) from the exploration, there were 52 clones having good genotypes; 2) from the 52 good-genotype clones, there were 16 clones having good compatibility; 3) in the period of 3 months, the best height growth was shown by clone number 6 with 27 cm; the best diameter growth by clone number 5 with 0.252 cm, and in term of leaf number, the best was shown by clone number 15 with 9.2 blades. In general clone number 6 showed the best compatibility and growth, with sprout life percentage of 37.03%; height growth of 2.7 cm; diameter growth of 0.114 cm and leaf number of 9.2 blades.

Information from Feces and Foot Tracks of Sambar Deer(Cervus unicolor), and Its Implication on PopulationEstimationThis study aims to investigate Sambar Deer (Cervus unicolor) ecology from the encounter of pellet piles groups and tracks in the study area. This study was carried out in Swanslutung village, one of the villages in the Paser District, East Kalimantan, where the hunting pressure is still relatively high and local people still depend on hunting for bush-meat of Sambar Deer. Further discussion addresses to find accurate and reliable scheme of population etimate. Average density estimate for the study area, based on the groups of pellet piles count, was 3.01 + 0.17 individuals/km2. Tracks can give information about sex and age classes, some of essential parts to study population dynamic of Sambar Deer. Dispersion of pellet piles groups and tracks can be used in tracking to study home range and territories of the species.

Effects of Composted Sawdust of Falcata Media and Slow Release Fertilizer to Promote Pinus merkusii Seedling growth in Banyumas Timur FMUPhysical and chemical properties of the potting media, especially porosity and nutrient availability, are required to produce good quality seedlings of pine (Pinus merkusii Jungh et de Vries). Composted sawdust of sengon (Paraserianthes falcataria) wood is a potential material to be used for growing media of pine seedlings. However, since this material contains low nutrients, addition of a slow release fertilizer is required to meet the nutrient demand of seedling growth. The objective of this research was to determine the effects of wood sawdust compost and slow release fertilizer on the growth of pine seedlings. The experiment was arranged in a completely randomized design with two factors and four replications. The first factor was the rate of sawdust compost and the second factor was the rate of slow release fertilizer. Height and root-collar diameter were measured at 6 months of age. As the results, sawdust compost and slow release fertilizer gave a significant effect on height and diameter growths. However, the effect of sawdust compost on seedling growth depended on the rate of fertilizer. Combination treatment that gave the best seedlings growth was 100% sawdust compost + 0% soil (and 12 g fertilizer /1.5 liter media). The seedlings applied with this treatment had the mean height of 8.72 cm and diameter of 2.24 mm, which were significantly greater than the control with the mean height and mean diameter of 1.87 cm and 1.15 mm respectively.
