Implementation of Pentahelix Collaboration Model in the Development of Government Institution’s Potency as General Services Agency
Full text linkThe 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\u27s 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
Forecasting The Demand of Jernang Extract (Daemonorops spp) in The Export Market
Full text linkOne 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
The MPA\u27s Leadership Style in Community-Based Forest and Land Fire Management
Full text linkCommunity involvement in forest and land fires management at site level is important due to the community can play a central role in preventing forest and land fires. One of the programs that involves the community in controlling forest and land fires is the Fire Care Community or Masyarakat Peduli Api (MPA). The MPA institution is a group consisting of members who join voluntarily. As a organization, MPA requires leadership that is able to mobilize members to carry out their role. MPA Wonorejo in Musi Banyuasin Regency, South Sumatra Province, is one of the successful MPAs. In this case the leader of MPA Wonorejo received the Wana Lestari award from the Minister of Environment and Forestry in 2018. With the case study method, this research was conducted to explore the leadership style that has been applied to the Wonorejo MPA. The results showed that MPA Wonorejo\u27s leadership style is a transformational style with charismatic characters, inspires members, encourages intellectuality and provides individual attention. The leader of MPA has an important role in mobilizing MPA members to play a role in fire control
Effect of Mother Trees and Cuttings Material Position on the Stool Plants to Shorea leprosula Shoot Cuttings Growth
Full text linkVegetative propagation plays an important role to support Shorea leprosula’sclonal forestry development. This study aimed to determine the effect of mother trees and cuttings material position of S. leprosula shoot cuttings grow that 4 months of age. Complete Randomized Design (CRD) was used as the experimental design, which consists of two factors, i.e. cuttings material position (4 level) and mother trees (10 mother trees). The results showed that the interaction between mother trees and cuttings material position significantly affected the growth of height and the number of the leaf. The best interactions in height of growth values ranged from 7.83 to 8.83 cm and the best number of leaves ranged from 3.6 to 4.5 sheets. The single factor of the cuttings material position and mother trees significantly affected the rooting percentage, the number of the root, and the length of the root. The cuttings material position at 20 cm, 40 cm, and 60 cm found to be the best rooting percentage (84 to 88%), the cuttings material position at 40 cm and 60 cm found to be the best number of the root (4.04 to 4.43 pieces) and the best length of the root (10.23 to10.93 cm)
Impacts of gap planting on soil density and erosion
Full text linkBy 2016, there were 32.70 million ha of degraded forests in Indonesia. If it isnot quickly rehabilitated, there will be land use changes and expansion of industrial forest plantation, which significantlyaffects itsbiodiversity and environmental. This research aims to study the impacts of the gap planting technique with red jabon on soil density and erosion. The research used: (1) the gap planting technique of red jabonwitha proportion of the total gap area to thetotal natural forest area of 40%: 60%, planting distance of 4m x 5m, and the number of trees planted of 200 stems/ha, (2) Digital-Humboldt Static Cone Penetrometer to measure soil density, and (3) stick for soil erosionmeasurement. The results showed that gap planting with red jabon to rehabilitate degraded natural forests increasedthe soil density, but itsvalue was categorized as a very loose soil class. On the other hand, the soil erosionin gap area was lower than in degraded natural forest area, because the condition of a part of the degraded forest was unvegetatedland, and there were the wastes of branches, twigs, and leaves as well as grown grasses on the soil surface that hinder the soil erosion in the gap area. This research concluded, that the impact of the gap planting on soil density can be neglected, and the impact of the gap planting on soil erosion is positive. Further research on social-economic, biodiversity, effective and efficiency aspects of the gap planting technique for forest rehabilitation are needed before its implementatio

Full text linkJabon 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
