Abstract

The case study was conducted in the area of Acacia mangium plantation at BKPH Parung Panjang, KPH Bogor. The objective of the study was to formulate equation models of tree root carbon mass and root to shoot carbon mass ratio of the plantation. It was found that carbon content in the parts of tree biomass (stems, branches, twigs, leaves, and roots) was different, in which the highest and the lowest carbon content was in the main stem of the tree and in the leaves, respectively. The main stem and leaves of tree accounted for 70% of tree biomass. The root-shoot ratio of root biomass to tree biomass above the ground and the root-shoot ratio of root biomass to main stem biomass was 0.1443 and 0.25771, respectively, in which 75% of tree carbon mass was in the main stem and roots of tree. It was also found that the root-shoot ratio of root carbon mass to tree carbon mass above the ground and the root-shoot ratio of root carbon mass to tree main stem carbon mass was 0.1442 and 0.2034, respectively. All allometric equation models of tree root carbon mass of A. mangium have a high goodness-of-fit as indicated by its high adjusted R2.

Abstract

Community forest (hutan rakyat, HR) in Java and Madura Island has been rapidly increasing. During 2003–2010 period, the average increment of HR was 200,000 ha year-1. Due to that, Ministry of Forestry wants to expand the financing services not only to community forest plantation through revolving fund scheme called as PDB-HTR (outside Java), but also to the development of community forest through a revolving fund scheme called as PDB-HR (in Java). Expansion of this service is basically an institutional development effort means improvement of the rules of the game (i.e. credit scheme) and player of the game (organizations). Analysis on this paper is directed to provide input for the institutional development for PDB-HR by the use of 5 approaches to institutional development, and institutional analysis and development framework (IAD). The results showed that there was a need to improve PDB-HTR scheme, including the basis of loan calculation, credit rationing, the target group, the credit ceiling, and the payment system. Based on institutional perspective, some principles that should be followed to support the poor to access the credit were simplicity, accessibility, conformity, feasibility, sustainability, transparancy, supervisory, assisting and facilitating, and learning.

Abstract

Being established in 2004, Gunung Merbabu National Park (GMNP) is one among several new national parks in Indonesia. Ecotourism activities in this area have not been properly developed by Perum Perhutani (as the past management authority) although the area is very potential to be developed as an ecotourism site for activities such as nature interpretation, apart from camping and hiking which are already carried out. With the change of the area’s status into a national park, the opportunity of ecotourism development is increased as the area is presently managed by a management authority named Gunung Merbabu National Park Office. As a part of ecotourism, nature interpretation is very important in connecting visitors to natural resources, which is one of the urgent services of GMNP. The objective of this research is to develop interpretation planning of various nature tracks in the park, based on the tracks’ resources and users’ demands. The Query Builder tool was employed in the selection of the user-oriented nature interpretation tracks. The synthesis of tracks’ resources and users’ demand resulted in 8 tracks, e.g. Selo–Puncak, Tekelan–Puncak, Selo II, Selo III, Tekelan IV, TWA–Krinjingan Waterfall, TWA–Watu Tadah Waterfal, and TWA–”Dufan”.

Abstract

Conflicts between government and local peoples over national park resources have been occurring in Indonesia, for instance in the Halimun-Salak Mountain National Park (TNGHS).  The research were directed to describe the opinion, relationship, access, and rights of the peoples in term of the TNGHS resources utilization.  Further objectives were to identify the causes of the settlement problems at the TNGHS and to formulate the alternative solutions of the problems.  The results showed that conflicts at Halimun-Salak areas have been occurring since the Dutch colonization period. The policy of the TNGHS area expanding (from 40.000 to 113.357 ha) in 2003 and different perception between the government and the peoples regarding to the values to the forest had made the conflicts extended.  Choosing the most appropriate solution from 3 alternative solutions namely: solving the problems of resettlement and law enforcement, revising the policy of TNGHS extension, and accommodating settlement in the special zone were strongly recommended.

Abstract

Sumatra Island in Indonesia has a high potency of plants diversities. Traditional people  have a local wisdom, like using plants extract for pest control which considered as an alternative technique that practical, economical, and environmentally safe. The aim of this study was to do inventory on pest control plants widely used by traditional people in the island.  In order to analys the pest control efectivity of the plants, analysis on bioactivities of crude extracts on pest Spodoptera litura was done in invitro scale.  The research was carried out in Rejang Lebong District, Bengkulu.  Bioactivities test was done in Laboratory of Forest Protection, Palembang Forestry Research Institute. The results revealed as much as 25 species plants potential as biopesticide. Among these plants, 5 species used as fish poison, 17 species used as pesticide, 7 species used as rat poison, and 1 species used as nematode poison. Traditional people in Rejang Lebong District have a long history using these plants regularly to control some pests. Sitawar (Costus speciosus), puar kilat (Globba sp.), and legundi (Vitex trifolia) extracts affected mortalities and inhibitor S. litura development significantly.

Abstract

Yapen Islands Regency has a very potential and feasible capital to be developed as a tourism attraction object. However, its ecotourism management does not optimal because of several constraints such as lacking institutional capacity of ecotourism management, weak attraction management, less spatial planning of tourism, and ineffective promotion and marketing, as well as problems on regional security. This research was conducted to formulate strategies to develop the islands ecotourism. The results showed that most of the tourism attractions (sea, water, and land ecotourism objects) in Yapen were feasible for further development ecotourism attractions. However, some of the potential tourism objects were not yet possible to be developed due to some barriers and constraints, i.e. unsupportive market potential, bad access due to location of the objects, below-standard management and services, poor accommodation, and high similarity with other objects.  The research, therefore, recommends that pessimistic strategy should be applied in overcoming the problems.  The strategy should be supported by arrangement of the tourism space, development of attractions management, development of promotion and marketing, development of regulations and management in ecotourism organization, and creation of a conducive and secure situation, both within and outside the tourism area.

Abstract

As the importance and threats of wildlife resources in Melanesia are widely recognized, their appropriate use is critical to achieve sustainable development in the country. An underestimated relationship between the status of the species with forest condition and food security is discussed. Being as nutritious as conventional imported red meats, bandicoots are also considered as the most rapidly breeding marsupial. The taxonomy, morphology, habitat, and reproductive characteristics of the family Peroryctidae (bandicoots) are succinctly described in order to elucidate the species potential in continuous controlled harvests in the wild and its eventual farming, until now successful abroad with one species from a related family. This effort requires the application of proper regulations that guarantee continuous harvests in accordance to the population dynamics.

Abstract

Twelve eucalyptus hybrid clones (6 grandis-camaldulensis i.e. GC and 3 grandis-urophylla i.e. GU hybrids) and 3 local landraces (E. camaldulensis, E. tereticornis, and E. urophylla) were established in Gede, Sokoke, and Msambweni in the Coast Province of Kenya in 2002, to compare growth, survival, and adaptability in the 3 sites.  By the end of the 1st year, trees in Sokoke were more than 3 times the mean height of those in Gede and Msambweni. However, these growth advantages during the 1st year in Sokoke were not maintained and by year 2 Gede had caught up, although Msambweni still lagged behind. By age 5 there were significant growth differences between clones. Of the tree sites, Msambweni had the lowest tree growth.  GC167, GC14, GC581, and GC584 proved themselves as the better clones, while E. camaldulensis and E. urophylla were the better local land races. Overall, the “local land races” performed poorly in all sites.  Survivals were over 80% in all sites for the best performing clones. However, in Sokoke, 1 clone died (GU7) while another (GU8) had a survival of less than 20%, while EC and ET had survivals less than 35%. GC796 died in Msambweni and had 8% survival at Gede. The poor survivals in Sokoke may have been due to a severe drought in the 3rd year.  The initial outstanding growth performance in Sokoke may have been due to the fact that Sokoke was a ‘virgin’ forest site and presumably more fertile than the other two sites. These results show that recommendations on outstanding clones or new germplasm for planting or sale to farmers are best done at the end of the rotation for a particular intended product or use.

Abstract

Furniture is a major export commodity in Indonesia with a total value of USD 1.96 million in 2007.  Jepara District is one of the key location for wood furniture production with 15,271 furniture related business units employing 176,469 workers.  However, inefficiencies and power imbalances throughout the furniture value chain have resulted in overharvesting and uneven distribution of gains among the industry’s actors.  In contrast to price-setting international furniture retailers, small-scale producers enjoy the least value from their products.  In order to increase added value and competitiveness, small-scale furniture producers have made efforts to upgrade by harnessing their social network and institutions.  This paper describes small-scale furniture producers’ efforts to upgrade by utilising their social network and institutions in Jepara.  Data was collected through in-depth interviews with members of the small-scale furniture producers’ association.  The research provides insight into the nature of social networks and information flow and develops future scenarios to upgrade.  The scenarios will not only benefit the furniture industry in Jepara, but may also be adopted for similar industries throughout Indonesia and the world, and potentially improve many people’s economies and livelihoods.

Abstract

Peat swamp forest is an important pool of terrestrial carbon stock (C-stock). Therefore, research on change of C-stock and its economic value of peat swamp forest conversion to pulpwood industrial plantation forest is important. The objectives of this research are to know the change of C-stock on peat swamp forest conversion to pulpwood industrial plantation forest, and to get the carbon economic value of peat swamp forest and pulpwood industrial plantation forest. The result showed that conversion from logged over and secondary forest causing the decrease of C-stocks of 103.53 and 61.02 t ha-1 year-1, while conversion from degraded forest causing the increase of C-stocks of 22.47 t ha-1 year-1. REDD project on pulpwood industrial plantation forest from degraded land causing the increase of NPV of 20.21% and 51.13% for compensation prices US$ 9 and 12 tCO2-e-1. REDD project with conservation on secondary forest gave lower economic value than pulpwood industrial plantation forest at all compensation prices simulation, and REDD project with preservation logging gave higher economic value than pulpwood industrial plantation forest at compensation price US$ 12 tCO2-e-1. REDD project on logged over forest gave higher economic value than pulpwood plantation at compensation prices US$ 9 and 12 tCO2-e-1 (both on conservation and preservation logging scenarios).
