Important Values of Agroforestry, Community Forest, and Agricultural Land on Conservation of Bird Diversity in Paliyan, Gunungkidul, YogyakartaAgroforestry is recognized as a land use management that capable to integrate the need of local peoples and the concern of biodiversity conservation. However, some contradictory results of studies made the importance of agroforestry on conservation of biodiversity questionable. To understand the role of agroforestry in biodiversity conservation, bird community assemblages of three land use types namely private forests, agroforestry and annual crops were compared. Single belt point count with a radius of 50 m was used to survey birds. In general species diversity in the study area was at a moderate level. Statistically, bird communities between sites did not differ significantly in term of their abundance, species composition, and diversity. It was because patch context plays more important role than patch content. However, it was found that in all community parameter agroforestry area has higher values than those of crops. Consistent with the previous studies, insectivorous birds were the most sensitive to land use changes. The conservation value of Paliyan area was relatively low, because most of species were abundant, and no species inhabit endangered status according to IUCN criteria. Implication of this research was that Paliyan area need a large-compact habitat to conserve high bird diversity.

Phenyl Certification: Public Perception and Impacts of Certification of the Local Scale Forest Management (Study Case in Selopuro and Sumberejo Villages, Batuwarno Sub District, Wonogiri Regency, Central Java)In 2002, Indonesian Ecolabel Institution (LEI) established the so-called Sustainable Community Based Forest Management Certification system (PHBML). In 2004, with a PHBML certificate award, the community forest management units in Selopuro and Sumberejo villages, Batuwarno sub district, Wonogiri Regency, Central Java were anknowledged as the best institution in sustainable yield function, social function, and ecological function aspects. This research was aimed to find out the community's kind of perception, as well as that of KPS (Certification Farmer Community) officials and members in particular, to PHBML certification implementation. Also, the study was intended to discover the impact of PHBML certification upon the local scale forest management.The research findings indicated that the community's level of understanding to PHBML certification was poor when compared with that of KPS officials. This condition due to the official failure to share the knowledge they had receivedfrom NGO with the KPS members. With PHBML certification, the institutional management by forest farmers had been proven improved however, there have not been yet any significant improvement to farmer income, and to forest product marketing. In addition to this, what was meant by significance, did not fully answer the farmer expectation of better sustainable forest principle realization.

Good Forest Governance: A Necessity in Sustainable Forest Resource ManagementForest resources development is one of natural resource management sectors implemented centrally during the period of New Order (Orde Baru). Forest resource management was executed exploitatively and centrally without considering local and regional aspirations, causing abandonment of local communities. Communities living near and in the forest were neglected and did not have any access to gain forest benefits appropriately. This has caused conflicts between state and communities upon forest resources utilization that to some extent has initiated forest resource degradation.Since the political reformation in 1998, along with more democratic and stronger civil society in Indonesia, good forest governance concept was believed as a strategy that is able to accommodate the dynamic and answer various problems in forest resource management. In this concept, state has to acknowledge its inadequacy in forest resource management. Government should share roles and authorities to other stakeholders in proportion to each capability. Government was forced to be able to accommodate and provide participatory space to the communities in every step of forest management activities. Additionally, ecological aspect has also to be the primary consideration in this strategy. By applying good forest governance concept that is always based on social and ecological aspects, it is expected that forest resource sustainability and community welfare improvement could be realized.

Utilization of Sawdust to Produce Ethanol Using Delignification Pre-treatment with White Rot Fungi Phanerochaete chrysosporiumCurrently, Indonesia is in the middle ofpetroleum crisis. One ofthe alternative fuels which can be used as a petroleum substitute is ethanol. Ethanol can be produced from timber waste (sawdust). Indonesia in 2003 had timber waste potency of about 3-4 millions m3. However, ethanol production from sawdust has problems due to its lignin content. Therefore, research on bio-delignification treatment of sawdust prior to ethanol making process is required. In the present study ethanol was produced by simultaneous saccharification and fermentation (SSF) using crude cellulose from Trichoderma viride and Saccharomyces cerevisiae. The raw materials for ethanol production are sengon (Paraserianthes falcataria (L.) Nielsen syn.), meranti (Shorea sp.) and teak (Tectona grandis LIIVN.f.) sawdust after pretreatment with white rot fungi Phanerochaete chrysosporium for 10, 20 and 30 days incubation time. The yield of ethanol was between 1.65-44.83 g/1. The best combination treatment is sengon sawdust with 30 day incubation time.

Epicormics Root: Emerge Variation and Its Effect on Teak (Tectona grandis) Seedling growth Epicormic shoot is an adventitious shoot appearing from the dormant buds. The formation of the shoots is influenced by environmental conditions such as drought, excessive crown opening (by thinning) or by shoot death, but genetic factor also plays a role. Epicormic shoot is assumed to negatively affects plant growth. The study aims to identin) family variation in tendency to form epicormic shoots and to examine the effect of epicormic shoots on seedling growth of teakThe study was conducted in 2006 on teak plantation in compartments 37b, 38c, and 38d, RPH Mangkang, BKPH Mangkang, KPH Kendal. Plant materials used were 6-month teak plantation named as prospective teak plantation (Jati Prospektip. The research was done in Randomized Completely Block Design using 28 seedlots/families (clone number 1 to 28), 3 treeplots, and 3 blocks as replication; and 2 silvicultural treatments i.e. with epicormic shoots and without epicormic shoots (shoots being cut).Results showed that seedlots with the highest tendency to form epicormic shoots were number 5, 18, and 25, while those with the lowest tendency were 6, 10 and 12. The existence of epicormic shoots negatively affected plant growth both on height and stem diameter. In two months, height and stem diameter growth of plants without epicormic shoots were 81.0 cm and 1.29 cm respectively, while those with epicormic shoots were only 69.1 cm and 1.13 cm respectively. Two families showing the highest growth performance were families 14 (with height and diameter growth of 95.6 cm and 1.50 cm) and 22 (94.2 cm and 1.47 cm).

Model of Taper Curve of Teak Stem (Tectona grandis)Detailed information on tree volume for fancy wood, such as teak, is important to estimate its financial value. Therefore, a method of estimating stem volume in portion wise is developed. The objective of this study was to apply a parabolic taper curve in various tree strata. Data of stem diameter at any relative height were collected from selected felled-tree samples according to stem quality both in the state and community forests by section wise measurement. Regression analysis was applied to estimate parameter and to test the suitability level of the parabolic taper model. The results showed that parabolic taper model could be used to describe the stem curve of clear bole stem in state forest and the stem curve up to tree height with minimum diameter of ca. 10 cm. In the state forest, the parabolic taper model was fit to medium and large diameter classes or in the intermediate and dominant strata. For small diameter class or in suppressed stratum, the model was not sufficiently fit. On the other hand, the parabolic taper model was fit to all samples from community forests because the samples comprised the stem of best quality from the stand. The parabolic taper model was suitable to apply on high quality stems which were characterized with healthy, cylindrical, and straight stem, high clear bole, and straight grain.

Abundance and Diversity of Bawean Deer Foods in Bawean Wildlife Sanctuary,Bawean Island,East JavaBawean deer (Axis kuhlii) is an endemic species to Bawean. Habitat change and loss, land conversion, and over exploitation affect the availability of potential food forBawean deer. The aims of this research were to identifi types ofpotential food for Bawean deer in Bawean Wildlife Sanctuary, the abundance ofpotential foods in Bawean Wildlife Sanctuary and the diversity of such potential foods. Data collected using line transects whose length was adjusted according to field condition. The line transects were located in parallel to natural trail of study area. Observation was done in the plots established along transect, where plant being eaten by Bawean deer was found. Plot has a circular form with diameter of 3.14 m. Distance between plots was determined to be 100 m. Indicators used to collect data were feces, footprint and bite or chew mark on food plants. Identification ofplant species was conducted directly for every plant which showed bite or chew mark Data concerning type ofplant and its number, part of plants which was bitten or chewed and plant height were recorded. Abundance will be determined from the number of potential foods in each location. The results were afterwards compared among three forest regions. The diversity of food plant species was determined using Shannon index. The result showed that there are 29 plants considered as potential food for Bawean deer. Most of the plants are grasses, and herbs, while woody plants are found in a small number. Leaves, shoots (buds) and fruits are part of plant often being eaten. There are 14 food plants occurred in Gunung Mas forest region, 27 food plants were found in Gunung Besar forest region and 13 food plants in Tanjung Cina Island. Taliata, rumput padang and gadung have high abundance in Gunung Mas forest region, the smallest abundance was occupied by kayu flat. Kabek-kabekan putih, lading-ladingan and taliata showed the highest abundance in Gunung Besar forest region, while karangsang has the lowest abundance. In Tanjung Cina Island, high abundance was dominated by gadung, taliowar and lading-ladingan. On the other hand, talicacing, kayu tekek and rombok putih showed low abundance. Among three study areas, Gunung Besar forest region has the highest diversity index, followed by Gunung Mas forest region and then Tanjung Cina Island.

Effect of Drying Method and Lumber Dimension on Drying Rate and Defects of Suren WoodEfforts to improve productivity of wood industry must be supported by increasing supply of wood as raw materials. The limited wood supply due to natural forest degradation can be increased by wood harvested from plantation forests, including wood of suren (Toona sureni Merr) as one species composing the forests. In timber processing wood drying is an important aspect determining product quality. This study aimed to identify the effect of drying method and sortimen dimension on drying character of suren wood.Trunks of 3 suren trees of seven to nine years old were cut from Manggihan village, Getasan district, Semarang regency. The bolts were sawn (using blambangan method) to obtain sortimen papan wood of 3 cm (thickness), 8 cm (width), and 210 cm (length) and sortiment usuk wood of 4 cm, 6 cm and 210 cm. Beside two levels of sortimen size, two levels of drying method, e.g. natural and solar drying were also used in this research. Resulted data were analyzed with factorial complete randomized design. Measured parameters consisted of drying rate, dimension shrinkage and some drying defects e.g. bowing, cupping, end check, surface check and fungi infection.Research results showed that drying methods significantly affect drying rate, but not other parameters. Also, product dimension affects significantly to drying rate, but not other parameters. Interactions between the two factors did not give any significant effect on all parameter. To produce the same drying level on the same product size, solar drying method is faster than natural one. To reach dry wood with 14% moisture content in solar drying method, sortimen papan and usuk needs 23 and 26.8 drying days respectively, while in natural drying method, the same product size needs 44.6 and 48.50 days of drying respectively.

Measurement of Extractive Content and Color properties on Black-streaked Heartwood of Teak (Tectona grandis)Teak (Tectona grandis L.f) in certain areas of Java usually has black streaked heartwood or has been known as "doreng". In general, the color of wood is related to the kinds and amounts of extractives, therefore, black streak that appeared on the heartwood was studied by means of color measurements and the determination of extractive content. The study was made with 13 trees of black streaked heartwood and 5 trees of normal heartwood. The wood powder (40-60 mesh) was extracted successively with ethanol-benzene (1:2, v/v) for 8 h and hot water for 3 h. The used system of color measurements was CIEL*a*b* which represents brightness, redness and yellowness. The discolored wood was contained substantially more ethanol-benzene soluble extractive content (12 - 22%) than did the normal heartwood (7 - 11%). The yield differences of hot-water soluble extracts were not as pronounced. Beside the brightness (L*), the differences in redness (a*) and yellowness (b*) between the normal (L* = 51-61, a* = 4 to 7, b* = 24 to 28) and black streaked heartwood (L* = 42-51, a* = 6 to 9, b* = 20 to 25) before the extraction, were notable. The total color differences ( E*) before and after extractions, however, were not significantly differed between the discolored ( E* = 6 to 13) and normal heartwood ( E* = 5 to 11) parts. Correlation analysis revealed strong correlations between ethanol-benzene soluble extractive content with L* (r = -0.97) and b* (r = -0.94). The hot-water soluble extract was moderately correlated with a* (r = 0.54) and the difference in redness ( a*) before and after extractions (r = 0.75).

Evaluation of Provenance Trial of Eucalyptus urophylla S.T. Blake Growth Age 20-Year-old in Lad Krating , Chachoengsao Province, ThailandGrowth characteristics of a wide range of provenance trial of Eucalyptus urophylla established at Lad Krating Plantation, Chachoengsao Province were assessed at 20 years of age. The trial was established to ascertain the extent of variation within the species, identify promising sources for the immediate seed supply and provide information on superior sources for selection. The trial consisted of 18 provenances representing six islands in Indonesia, viz. Flores, Lomblen, Pantar, Alor, Wetar, and Timor. Results from the present study indicated that there were significant differences in survival, tree height, clear bole, diameter at 10 cm above ground level (D10), and diameter at breast height (Dbh) among provenances. Meanwhile, the difference in crown diameter among provenances was insignificant. The present results recommended 6 provenances, viz. Mt. Lewotobi (Flores), Mt. Wasbilla (Pantar), Mt. Kerbau (Lomblen), Mt. Lewerok (Flores), Ampui (Alor), and Mt. Lakaan (Timor) as the best performing provenances for the next selection process and the most promising seed sources to be used in increasing the plantation productivity at Lad Krating.
