Jabon putih (Neolamarckia cadamba) is a widely distributed potential fast-growing species and is thought to be associated with extensive genetic diversity. The aim of the research was to assess the morphological and genetic variation of jabon putih seedling based on AFLP markers. Randomized block design with 4 replications was used to assess seedling morphological variation on 31 families from 4 populations (Kapuas, Kampar, Nusa Kambangan, Pomalaa) based on traits of seedling height, diameter, sturdiness quotient, number of leaves, leaf length, and leaf width at nursery. AFLP Analysis System I Kit by using dry leaf samples from each family was used. Characteristics of jabon putih seedlings had variation among populations and families within population. Genetic variation within population based on morphological traits had the similar trend with result of AFLP analysis. The highest genetic variation was detected in Kapuas population, followed by Pomalaa, Nusa Kambangan, and Kampar populations. Cluster analysis and UPGMA method had 2 cluster and put down most of families from Kapuas in one cluster separated from other families. Based on the genetic similarity analysis, 26 families could be considered as potential families for the establishment of breeding populations. The study has important practical implications for genetic resources management and for future breeding programs of jabon putih.

Kabesak (Acacia leucophloea) is a particular plant species and recognized to have important benefits tothe local people of Timor Island. The people of Timor Island use kabesak leaves as animal feed in the dry season and kabesak wood is used as building materials and furniture. The purpose of this study wasto determine the stand and site characteristics ofkabesak in the western region of Timor, Indonesia. The means of density, frequency, dominance, and importance value index were analyzed. The results showed kabesak stand structure in secondary forest land, grassland, and shrubs, as well as garden showed the J-inverted shaped, which implies that natural regeneration was a proper continuation. Kabesak had significant associations with a few plants’ species, both negative and positive types. The result of regression analysis of the principal components showedthat the contribution of edaphic factor influencesthe population density of kabesak.Silt fraction and phosphorus content were found tohave the highest positive effect on the density, while sand fraction and sodium content were found to havethe highestnegative effectsof kabesak. A test for altitude with Tukey test (α = 0.05) reveals that kabesak from 0-300 m a.s.l., 300-600 m. asl., 600-900 m a.s.l. werenot different from each other, while altitude >900 m a.s.l. was significantly different from the other groups.

One indicator of a country’s progress is economic growth. In an economic growth, export is an important component in contributing to a positive trade and balance. Indonesia as one of the developing countries always looking for a various way to increase the number of export value. To achieve thesegoals, Indonesia started the exploitation of its forest to obtain more valuable commodities that are in demands by the global markets.One of the high-value forest plants that have the zero potential to the environment damage is the Jernang extract (Daemonorops sp)that has been used as a raw material in the manufacture of the traditional medicine in several countries, e.g. China, Taiwan, and Hong Kong. The opportunity to make Jernang extract as one of the major foreign commodities for the country’s development is relatively open. But in the current situation, the utilization of Jernang extract has not been fully used and the matter of fact that there is limited information about the world’s demand for the Jernang extract. The aim of this study isto find out the possibility of the needs of Jernang extract in the future. All the data regarding the Jernang extract will be processed using the methodology of Single Exponential Smoothing Techniques. The result of this studyshows that the demand of jernang was fluctuated but still in the trend of large demand. This study recommends that the government need toencourage people to develop Jernang plantation.

Teluk Adang Nature Reserve (NR) is one of the Nepenthes habitats in East Kalimantan. One of the four Nepenthes species that can be found in this nature reserve is Nepenthes reinwardtiana or by local people known as anjat datu. The objectives of this study are to determine the population of N. reinwardtiana in Teluk Adang NR by calculating its density and frequency, and to know its distribution pattern using Morisita index and spatial analysis approach in the form of Nearest Neighbor Analysis and Multi-Distance Spatial Cluster Analysis (Ripley's K Function). To know its distribution pattern, a census method by creating 5m x 5m plot along the observation track was done. The results showed that there were 2,943 individuals of N. reinwardtiana in Teluk Adang NR. Standardized Morisita Dispersion Index was 0.51, 0.55, and 0.51 in Tajur Village, Pasir Mayang Village, and Janju Village, respectively. The spatial distribution of N. reinwardtiana was clustered. Research on the distribution of N. reinwardtiana and its habitat needs to be carried out continuously so that its population in the Teluk Adang NR can be monitored.

Agarwood or eaglewood is a trading name of a solid resin from the two genera Aquilaria and Gyrinops which belongs to the Thymeleacea. The declining population of agarwood in natural forests placed the commodity regulated in Appendix II of the Convention on International Trade in Endangered Species (CITES). Indonesia as one of the habitats of those two genera and also the main exporting country of agarwood has an interest in ensuring the sustainability of agarwood. This study aims to provide an updated habitat of agarwood-producing trees and to estimate the potential density of the agarwood species. Research conducted in the forest of Natural Tourism Park of Beriat, West Papua, showed that Aquilaria filaria grows well in the forest. Five adult individuals were found in karst forest where 72% were dominated by small trees (DBH <20 cm). In terms of forest communities, Aquilaria's basal area reaches 1.9% of the total basal area and has a low importance value of 0.016 in the first dimension of Principal Component Analysis (PCA). The overall potential for agarwood-producing trees was estimated to be only around 2.50 and 2.89 for tree and seedling per hectare, respectively. The potential density is decreased when compared to the estimated density carried out 20 years ago which was estimated at around 4.33 trees per hectare. Efforts to protect agarwood, one of which is by determining trade quotas, need to be carried out optimally in order to minimize the decline in agarwood populations in their natural forests.

Occupational safety and health (OSH) issues in the Indonesian forestry sector have not been addressed properly even though activities in this sector pose a high risk of OSH disorders. The standard instrument (applies on a national scale) to ensure OSH protection in each business units is the Sistem Manajemen K3 (SMK3, Government Regulation Numbered 50 Year 2012). At present, not many forest management units in Indonesia are willing to implement integrated SMK3, because of the assumption that SMK3 is a cost-centered activity. This study aims to present an overview of SMK3 implementation cost (for 64, 122, and 166 criteria) in a Forest Management Unit (FMU) X, as well as analyzing financial capacity of the FMU X to allocate sufficient funds for the SMK3 implementation. The results showed that the Acacia mangium plantation in the FMU X is a feasible business, indicated by the Net Present Value (NPV) of IDR377,690,545, Benefit-Cost Ratio (BCR) 3.96, and Internal Rate of Return (IRR) 25.02%. Further analysis shows that FMU X has good financial ability to support any cost required in implementating SMK3. It is the best for the FMU X to implement 166 criteria (advanced level) of SMK3 (at a cost of IDR704,598/ha/year, NPV ofIDR376,393,262, BCR 3.92, and IRR 24.75%).

The maturity of the R&D institutions through Public Service Agency (BLU) is an effort to increase the relevance in responding stakeholder needs. BLU is present as a solution for R&D institutions in providing goods and/or services that are sold based on the principles of efficiency and productivity. However, the strategic plan for the BLU formation is prepared by submitting a substantive, a technical and an administrative requirement. Therefore, this research facilitates thesubmission of these requirements throughthe Pentahelix Collaboration Model, whichis the optimization of 5 (five) roles: business, government/management, community, researchers and mediaby implementing the roadmap at the Forest Tree Seed Technology Research and Development Center. Thecase study steps to improve all the roles conditions was by adapting Kurt Lewin's action research into 4 (four) stages: planning, action, observation, and reflection. The role of the business unit is emphasized on market differentiation and business strategy by considering an opportunity to increase revenue realization/financial forecasting ratio. The role of management is emphasized on budget flexibility and remuneration by considering cost accounting and its unit cost calculations. The role of the community is emphasized on the conducive policies by accommodating stakeholders’need. The role of the researcher is emphasized on the innovation of forest seed’s products/services by improving service quality and managing it with corporate style principles. The role of the media is emphasized on the professionalism of human resources by considering the community satisfaction index.

Acacia nilotica which is a plants of the genus Acacia which is known as one of the invasive genera. A.niloticais very invasive due to several advantages it has such as very large seed production, seed dispersal far enough by wildlife, young plants to grow very fast and are resistant to drought and fire. Some invasive acacia species can act as nurse plants for native plants, which increases the photosynthetic efficiency of native plants, and protects native species from extreme temperatures. Therefore, it is important to know the chance of recolonizing native plants in areas that are invaded by foreign species, by looking at the performance of plants seedlings under A.niloticastands. This study aims to determine the potential of A.niloticainvasive plants as nurse plants for local plants in East Timor. The stages in this research are the preparation of tools and materials, seeding of target species, selection of A.niloticastands as a nurse plants, selection of healthy target species seedlings to be planted, planting of target species seedlings under A.niloticastands, observing survival ability and species growth target. An analysis of the survival ability of the seedlings was carried out using the Kaplan-Meier survival curve. The results of this study are the angsana seedlings and kabesak in this study experienced many deaths, external factors such as high-temperature factors due to the long dry season suspected to be the cause. A.niloticashade does not affect the survival of the angsana and kabesak seedlings, allelopathy produced byA.niloticaplants accompanied by a drought in a long period of time causes the plantsis unable to act as nurse plants for kabesak and angsana plants.

Increasing the value of bark can be known through the characteristics of the bark such as physical properties, the grade of fiber quality and the chemical composition of the bark. The purpose of this study is to find out the characteristics of the bark of the acacia plant species (i.e. Acacia auriculiformis and Acacia mangium) of Industrial Plantation Forest. The characteristics of the bark observed includes physical properties, quality grade of fiber and chemical composition. The results of this study showed that the bark density, thickness and water content of A. auriculiformis were 1.18g/cm3, 1.55 mm and 35.27% respectively, while, the bark density, thickness and water content of A. mangium were 0.95 g/cm3, 1.23 mm and 48.21% respectively. The fiber qualities of both plants are classified as grade III. The extractive substance levels of A. auriculiformis and A. mangium were 23.06% and 20.63%, respectively. Based on the analysis with GCMS it can be seen that the main compounds dissolve-hexane from species A. auriculiformis were 2-phenyl phenol 33.6% and palmitic acid 13.5%. In the species A. mangium the main compounds soluble n-hexane were palmitic acid 28.97% and oleic acid 21.43%. The results of the analysis showed that these two bark species could potentially to be adhesives materials, tanning agent, particle boards, and inhibitors at the rate of corrosion of steel.
