Abstract

Indonesias forests have economic, social, and environmental benefits. Some national efforts, as well as support from the global community for sustaining forest development in Indonesia have been done. However, some problems were still reported during the implementation of the forest development. Thorough analysis was needed to formulate the root of the problems, and to identify solutions/supports to the current forest development to achieve its sustainability. Descriptive analysis was used in this study. The results indicated that sustainable forest development in Indonesia was still faced with the problems of uncertainty of management, insufficient management capacity, and lack of law enforcement. These conditions were indicated by high conflict of interests as well as lack of support from stakeholders, not enough forest management actions at site-level, and high forest degradation. Aiming at overcoming problems of sustainable forest development and maintaining sustainability of Indonesias forest, national forest management needs to embrace more space for communication, openness, mutual learning, collaboration in addressing forest conflicts, and determining the future direction of its sustainability goal of management.

Abstract

Phenolic is well known as a secondary metabolite that plays an important role in plant defense system. Information about the fungi-impeded role of secondary metabolite is important in achieving success of artificial agarwood production, in that fungi induction imparted to the selected potential trees will be more effective and efficient. This research was aimed to investigate the correlation of agarwood tree phenolics in relation with the susceptibility of corresponding trees to Fusarium solani attack in the formation of agarwood and observing total phenolics content of Aquilaria crassna and Aquilaria microcarpa trees prior to inoculation. Twenty trees of A. microcarpa at Carita, a Forest Area for Special Function (FASF) and ten of A. crassna at Dramaga Research Forest were inoculated with isolate of F. solani in spiral pattern around their stem from ground level to about 1.5 m in height. Prior to inoculation, wood strips were taken off from the stem for total phenolics content. The result revealed that total phenolics content and infection area tended to have a negative correlation. Since the quantity of agarwood is highly related with the infection area, then trees with lower phenolics content should be selected for the more effective and efficient artificial agarwood production.

Abstract

This paper provided information regarding artificial agar wood production. Fungi are considered as biological agent for agarwood formation and agarwood is assumed as tree defense mechanism product. This research was aimed at investigating the anti fungal activity (AFA) of Aquilaria crassna, one of the agar wood-producing trees, against Fusarium solani in vitro. Aquilaria crassna wood mill was extracted by 70% ethanol to investigate the anti fungal activity. The result are Aquilariacrassnaexhibited low extractives content, which was only 2.0% (w/w) and a low anti fungal activity in vitro, especially for ethanol extract. However, further fractionation and bioassay showed that the most active component was likely in the ethyl-acetate soluble fraction that exhibited strong anti fungal activity (52.5%) at 4.0% of concentration.

Abstract

Under  Pinus radiata plantations  where  the tree spacing  is wider  and most soils are phosphorus  (P) deficient,  the radiata  tree response to P fertilizer is expected  to be more influenced  by  the interaction between  the applied  P fertilizer, the tree and understorey vegetation.  Therefore,  a better understanding of the soil P chemistry under radiata pine trees in association  with  other  plants  is required.  We investigated  the effect of broom  (Cytisus scoparius L.) and ryegrass  (Lolium multiflorum) grown  with  radiata  seedlings  in Orthic Allophanic Soil treated with  0, 50, and 100 μg P g-1  soil of TSP on the pH and phosphatase activity in the rhizosphere soils under glasshouse condition. The pHs of radiata rhizosphere soils either grown with broom or grass were lower than  those in the  bulk soils and the bulk and rhizosphere soils of grass and broom,  whether  they  were grown  alone or grown  with radiata at the  applications of 50 and 100 μg P g-1 soil. These results suggest that P application enhanced root induced acidification  in a P-deficient Allophanic Soil under radiata.  The soils in the rhizosphere of grass and broom, grown in association with radiata, were also acidified by  the effect of radiata  roots.  Acid  phosphatase  activity in soils under  radiata,  grass and broom  decreased with  an increased  rate of P application. At all P rates,  acid phosphatase activity was higher in the rhizosphere of radiata  grown  with  broom than in the bulk soils. The phosphatase activity in the rhizosphere soil of radiata grown with broom was also higher than that of radiata grown with grass, but it was slightly lower than that in the rhizosphere of broom grown  alone. These results suggest that broom may have also contributed to the higher  phosphatase  activity in the rhizosphere soils than  in the bulk  soils of broom  and radiata when they were grown  together

Abstract

It is not easy to define color because it refers to psychological response of human. As a result, perception of color achieved by people is relatively different.  Wood color plays an important role in timber processing and it is an important consideration in wood identification. Each wood species has specific color and it becomes the species characteristic. Colors in wood are highly variable and unique features. Characteristics of wood color are influenced by extractive materials and moisture contents present on it. A standard of color measurement has been developed and it is called CIE model. The standard was developed to be completely independent of any devices and was based as closely as possible on human observation in color. CIELAB system is one of the simplest and most practical color measurement methods. The system has been used in one of the color measurement devices developed by Data Color International that is Microflash-200®. This research was aimed at translating interpretation of wood color by human eye into mathematical values so that scientific measurement of wood color can be studied. The measured wood color were 10 species of pines and 10 species of eucalypts woods in dry condition. The results showed that the two groups had different average of L*, a* and b* values. The average of L* for pine was 70.77, while eucalypt group made up to 52.40. It means that eucalypt group is darker than pine group. For a* value, pine group mean value is 20.23, whereas eucalypt group touches 19.11. In other words, pine and eucalypt group have an approximately similar redness. The b* value average for pine and eucalypt groups are 43.40 and 29.07, respectively. This value means that pine group is more yellow than eucalypt group.

Abstract

Pollen pattern dispersal in seedling seed orchard (SSO) is an essential part of a tree-improvement program. Two SSOs of Acacia mangium in South Kalimantan and South Sumatra that represent similar resources in different environments were used in this study.  Genotypes of all trees and seeds from a subset of 10 mother trees in each orchard were determined for 12 microsatellite loci, and parentage analysis was carried out. The results shows that the pollen dispersal pattern in both SSOs decrease with distance from mother tree. Patterns of pollen dispersal, dispersal distance and cumulative frequency of pollen dispersal distance were similar in both SSOs. Random pollen dispersal were found in both SSOs. About 80% of all crosses were found within a 40-m distance range with the most frequent pollination distance between mother tree and male male parents was 0-10 m. No self-pollinated seed was detected. Application of all these aspects found in this study such as random pollen dispersal and the effective pollen dispersal distance can be useful for establishing seedling seed orchard, clonal seed orchard and in other tree improvement activities of A. mangium.

Abstract

The efficiency of early selection was evaluated based on age trend in genetic parameters using tree height data that was measured periodically repeatedly up to age 3 years of age in four seedling seed orchards of Acacia mangium at South Kalimantan, Indonesia. The four orchards were grouped into two populations based upon their provenances, namely: Papua New Guinea (PNG) and Far North Queensland-Australia (FNQ). A model for time trend of genetic parameters was developed by fitting regression equation to the estimates of variances and correlations using tree height data as an independent variable. In both populations, genetic variances and total phenotypic variances increased along with the mean height. Trend of individual heritability along the rotation ages were almost stable at around 0.19 for PNG, and gradually increased from 0.36 to 0.40 for FNQ. Trend of genetic correlations between selection age and rotation age increased rapidly starting at around 0.5 for PNG and 0.6 for FNQ, then exceeding 0.9 at age four years in both populations. Genetic gains due to indirect selection increased with age, in which the gains in FNQ were generally larger than those in PNG. Selection efficiency based on gain per year as a ratio of the gains from indirect selection to direct selection may conclude resulted the optimum age for selection at age two years old in both of PNG and FNQ population.

Abstract

The rigidity and firmness of wooden construction and furniture those are joined by metal screws depend on corrosion rate of these metals. This paper examines the weight-loss percentage of metal screws used in wood samples that have been treated with water-borne preser vative (i.e.3% borax boric acid and 3% diffusol CB) and concurrently investigates the effect of brake fluid on preventing metal corrosion. Wood samples tested included three acacia and one eucalypts wood species which were grouped into sapwood and heartwood containing samples. Wood samples fastened with metal screws were freely suspended in glass jars that contained 25 ml of sulphuric acid (H2SO4) to keep the humidity rate above 90%. After 12 months, the metal screws lost their weight due to the corrosion brought about by the related factors either in separate individual or in combination, which comprised brake and fluid-dipping , wood species, wood portion (sapwood and heartwood), kinds of preser vatives used. Corrosion rates of metal screws fastened in eucalypts wood sample as indicated by the screw-weight loss (i.e. 5.8%) was more severe than that fastened in acacia wood. Furthermore, corrosion rate of metal screws as fixed firmly in sapwood sample proceeded faster than that in heartwood. This might be caused by the higher moisture content in sapwood. On the other hand, corrosion rate of the screws as fastened in waterborne-preser vative-treated wood samples was greater than that in non-preser ved wood due to electrokinetic characteristics and ionic potential exhibited by the preser vative thereby intensif ying the screw-corrosion process. Meanwhile, less severe corrosion was obser ved and recorded on the screws pre-dipped in brake fluid compared to those on the non-dipped screws
