Level of Food Preference of Bawean Deer (Axis kuhlii) on Food Species in Wildlife Sanctuary and Nature Reserve of Bawean IslandThis research has a background on the importance of food preference of Rusa Bawean (Axis kuhlii). This information can be used to ensure the adequacy of preferred food availability within their habitat. This paper aimed to estimate food preference of Rusa Bawean employing faecal analysis. The technique was selected because it is safe for the animal and is easy in data analysis and interpretation. To achieve the aim, quasi experimental design was applied to 30 vegetation plots and 60 faecal samples. Data was collected during January 2005 and June 2006 in the area of Wildlife Sanctuary and Nature Reserve of Bawean Island. Data was analyzed with chi-square test and food selection index. Result shows Rusa Bawean have preferences on some of food species, and they do not select their food species randomly according to its abundance. Preferred food species include Kabak-kabakan alas (Brachiaria distachya), Talioar (Panicum cordayum), Gadung (Dioscorea hispida), Andudur (Caryota mitis), Rombok putih (Merremia peltata), Pele (Urena lobata) and Kabak-kabakan merah (Ischaemum timorense). Whereas avoided food species include Lating-latingan (Scleria hebecarpa), Ancucu (Pericampylus glaucus), Lambu Merah (Paspalum conjugatum), Alang-alang (Imperata cylindrica), Padi-padian (Centotheca lappacea), Lente-lentean (Fimbristylis dichotoma), Taliata (Lygodium circinnatum ) dan Kayu sape (Symplocos adenophylla).

Effect of Tobacco Extracts on Apus Bamboo (Gigantochloa apus Kurz) resistance against Drywood Termite Cryptotermes cynocephalus Light (Gigantochloa apus Kurz) AttacksBamboo is one of community forest products and people use it for many purposes. Due to insect attack such as termite, the life time of bamboo product is short. To avoid chemical pollution in bamboo preservation process, tobacco extract was used.Tobacco was extracted in water, in the amounts of 100, 150 and 200 g in 1 l of water, at temperature of 70-80°C for 3 hours. Bamboo trees were cut, the bottom parts were soaked in tobacco extract solution for 1, 3 and 5 days. Samples were cut into 5 cm x 3 cm x bamboo thickness at the bottom, middle and upper parts of the bamboo tree. After being air dried, each sample was exposed to 50 dry wood termites in a small glass tube for two months.The results showed that bamboo preservation by diffusion with high concentration of tobacco extract (200 g tobacco extracted in 1 l of water) resulted in 61% termite mortality.

Study of Land Suitability for Protected Area Selection in Konak Forest Protection, Kepahiang Regency, BengkuluThe study aims to determine land suitability of the area into a forest protection by using field physical factors i.e. rainfall intensity, soil type, slope, and altitude. The research is conducted in Konak Forest Protection, Kepahiang, Bengkulu. Basic method used in this research was survey, with sampling and measurement in the field. The results shows the average value of forest protected areas: slope is 0-8% with value of 20, the type of land is podsolic (sensitive to erosion) with value of 60, and rainfall intensity is under 13.6 mm per day, with value of 10, and altitude is 500 meters above sea level. The total value of the factors is 90, far below the standard value of the protected forest which should be more than 174. This means that utilization for other functions, such as recreation area, city garden or land cultivation, will be more appropriate and useful than if only defined as forests protection.

Anatomical and Physical Properties of Mindi Wood (Melia azedarach Linn) from Community Forest in YogyakartaInformation about mindi wood characteristics is very limited while utilisation of this wood on our society is very extensive. Better knowledge on anatomical and physical wood properties of mindi wood optimizes its utilization. Therefore, this study aims to identify anatomical (macroscopic and microscopic) and physical (moisture content, specific gravity and dimensional changes) wood properties of mindi taken from community forests around Yogyakarta. The macroscopic structural characteristics results showed that annual ring appeared clearly at transversal surface, having single vessel, vasicentric and diffuse parenchyma, rough texture, straight fiber direction, and no resin canal. Cell proportion of wood showed that fibers occupy more than 44%, followed by vessel (20%), parenchyma (19%) and rays (15%). Wood fiber dimension showed fiber length of 0.83 mm, fiber diameter of 14.57µ, and cell wall thickness of 2.50µ. Physical wood properties showed that mindi has 31% moisture content and 0.416 of basic specific gravity. Wood shrinkage from green to kilndry on longitudinal was 3.94 %, tangensial 5.74 %, and radial 2.60 %, with T/R ratio 2.38. Based on T/R ratio value, mindi wood is not recommended for wood construction due to its low dimensional stability. Furthermore, mindi wood also has high longitudinal wood shrinkage and low specific gravity indicating juvenility.

This paper explores the ecological and socio-economic contribution of Mt. Elgon forest park, eastern Uganda. An effort was taken to evaluate the importance of Mt. Elgon forest park resources to the local people by using the local plant knowledge to value the forest park resources. An integrated approach of participatory rural appraisal (PRA), Participatory Resource Valuation (PRV), household survey, group discussions and forest walks were conducted during the months of June to December, 2008 in Mutushet and Kortek Parishes, Kapchorwa District. Using random sampling methods, 120 respondents were selected and interviewed. Ten forest uses were identified with the highest dependence being in the supply of timber for income and domestic building poles, the latter having the highest average annual household value of UGx. 67919 (US$37). The forest use most valued in both Mutushet and Koterk was medicine with an average annual household value of UGx. 60,371 (US$ 33) and UGx. 75,464 (US$ 42) respectively. The forest provision of medicine, domestic building materials, soil conservation, bush meat, charcoal and timber was more valued in Koterk, while provision of firewood, honey and pasture were more valued in Mutushet. The forest’s provision of food was valued equally in the two areas with an average annual value of UGx. 30,186 per household. Forest park resources accounted for 55% of the household income. Participatory valuation approaches are ecommended for estimation of forest park resources’ value in a non-cash economy.

The above ground biomass of Sengon (Paraserianthes falcataria) in the community forest of Bateh Village were estimated by developing allometric equations. To establish the allometric equations, 400 sample trees were measured to determine the relationships between tree height (H) and stem diameter at breast height (D). Eighteen trees of various sizes were cut to measure the above ground biomass (stem, branch and leaves). The results showed that a diameter of 1.3m above the ground (D) alone was a good predictor of tree height (H). When D was combined with H, r2 was improved somewhat for stem, branch and leaves biomass. The relationships among measured tree dimensions drew a simple linear in log-log scale diagrams with r2 over 0.9699, suggesting the growth patterns of tree dimensions were closely interdependent, whereas the allometric equations between D and H was approximated by the hyperbolic relation with r2 over 0.9141. The individual tree equations appear to be applicable over a wide area of sengon in the community forest of Bateh Village, Magelang, Central Java.

Interpretation of Stock Volume of Pinus merkusii using Aerial Photographs (Case Study in BKPH Majenang, West Banyumas FMUThe study aims to compile and analyse the growing stock volume of Pinus merkusii by using stand parameter measured through aerial photographs. The study was conducted by using black-white panchromatic aerial photographs produced in 2005 and the scale was 1 : 20,000. The study was conducted in Pinus merkusii taping plots in the Majenang BKPH, under the forest districts of west Banyumas, Perum Perhutani using tree height, crown diameter and number of trees per hectare as parameters. Data analysis was done to define the relationship among these parameters in regression equation. The steps of the study were defining measurement plots in aerial photographs, measurement of stand parameters in the aerial photographs and field observation. Data analysis was performed using micro computer. As a result, the regression equation for each location as follows: V = 72,415 – 0,231 N + 35,242 H – 24,454D – 0,923 (N x D), with the determination coefficient was 0,789 and the significance of 95%. Where: V = growing stock volume (m3), N = the number of trees per hectare, H = tree height (m) and D = crown diameter (m). It was concluded that number of tree per hectare, tree height and crown diameter were good predictors for standing stock volume of Pinus merkusii.

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.
