Abstract

Assessments of localized ecological and environmental impacts of charcoal production including effects on soils at kiln sites is seldom undertaken, with more emphasis being placed on the global effects of the practice such as forest degradation and deforestation. A study was undertaken in Narok, Eldoret, Moiben, and Turbo in Kenya on known charcoaling sites to investigate the impact of charcoal production on the soil chemical characteristics. Composite soil samples from 12 sampling points for all study sites were taken randomly at a depth of 0–15 cm. The samples were conditioned and analyzed for pH, particle size, Cation Exchange Capacity (CEC), extractable phosphorus, organic carbon, nitrogen, and exchangeable bases. A comparison of the soil properties between undisturbed sites and charcoaling sites showed significant differences for all chemical properties except CEC, Mg, and K. For the Moiben site, only the pH showed no significant difference (p < 0.05).  The observed high carbon content reduced with time for the one year following charcoaling activity and was attributed to soil erosion since charcoal production activities reduced the sites vegetation cover. Most chemical changes positively enhanced the nutrients content and availability, but were short lived probably due to soil erosion.  These results demonstrate the need to adopt technologies with minimum impact on the soil, or a shift to centralized production sites outside forest ecosystems or farmlands.

Abstract

Furniture industry had shown a long chain of production to consumption, from raw material producers (tree growers), semi-finished producers, finished product producers, and retailers to exporters. Jepara as a centre furniture industry in Indonesia incorporates around 15,000 business units and provide livelihoods to approximately 170,000 workers. This sector contributes about 27% of Jepara‘s people domestic income. Small and medium furniture enterprises (SMEs) have significant roles in the furniture industry as production structures are characterized by them. Power and information imbalance throughout the furniture value chain have resulted in problems of uneven distribution of gains among actors of the industry. SME furniture producers have experienced an unfair value added distribution. Hence, development of SMEs is important for strengthening the industry and expected to result in a portion of value added distribution to them.  We are trying to develop scenarios for SME improvement in the furniture industry in Jepara by identifying their problems and implementing Value Chain Analysis (VCA). VCA is an approach to describe SME producer relations with other actors in the industry and the governance type of their relations. Data is collected by interviewing selected SMEs from the association of small scale producers in Jepara to get detailed maps of their value chain. The research will produce future scenarios and intervention points to improve small-scale producer sustainability and better value added distribution among furniture actors. The scenarios will not only benefit selected producers but also the furniture industry of Jepara, and can be adopted for similar industries throughout Indonesia and abroad.

Abstract

Increasing population and exploitation of Toba Lake catchment area had caused environmental degradation. Various institutions attempt to rehabilitate the area, including Ministry of Forestry through the ITTO project. The project aims to gather all stakeholders of restoration of Toba Lake catchment area ecosystem and facilitate them to exchange knowledge and information, so that they could have same understanding and build a network. This study was conducted in 3 districts, i.e. Samosir, Simalungun, and Karo. The respondents were selected using snowball sampling. The data was analyzed using stakeholder mapping. The study shows that key stakeholders of Lake Toba catchment area ecosystem restoration are government institutions which their role and functions are still limited according their main tasks  which hindered  synergic activities among them. There are potential conflict and collaboration among stakeholders which should be managed for the benefit of the project.

Abstract

Dipterocarpus hasseltii (palahlar) and Dipterocarpus retusus (mountain palahlar) are plant species of Dipterocarpaceae family that originate from West Java which population is getting rare. Information about growth development and genetic variation of palahlar is important to support culturing program and its genetic conservation. One of the techniques to study palahlar growth is through observation of the plant height and stem diameter increment. DNA analysis is use to gain information of palahlar genetic diversity. One of the DNA based molecular marker widely used as plant genetic marker is RAPD. There were 2 primary that resulting the best amplifying quality in genetic diversity analysis that was OPO-13 dan OPY 20. Analysis result with POPGENE 32 was resulting average genetic diversity between classes as much as 0.1869. The biggest genetic diversity for palahlar was on the medium growth class  as much as 0.2498 dan for mountain palahlar was in small growth class as much as 0.2240. Cluster analysis shows that there were 2 big groups that were medium-high growth class group   and small growth class group. Dendrogram shows that there were 2 species in one group, that was palahlar and mountain palahlar that was in one group of small growth class. The closed genetic distance existed between medium growth class group of palahlar and high growth class group (0.0383), while the far distance is between palahlar of small growth class group  with mountain palahlar of mediaum growth class group as much as 0.1826.

Abstract

This paper presented result of the study on extraction of felling waste by manual bundling systems: assessment of qualitative performance The study is carried out at an Industrial Plantation Forest in South Kalimantan. Two bundling methods were apllied in this study, i.e. bundling by the use of net and rope.  The results of the study showed that adaptation level of workers for the systems were good enough. The most mistaked work elements for both methods was compacting the waste for bundling, while the less mistaked work element was unload travel to the waste location.

Abstract

Devolution of forest resource management can be suggested to create the everlasting forest, give more equity to society and be more efficient. The aim of this writing is to analyse (1) the devolution of forest resource management in Indonesia, especially society forest by examining the actor dimention involved in  role transfer and right dimention and responsibilities which are devoluted; (2) the realization of policy implementation of forest resource devolution at field level;  (3)  the implication of devolution to forest resource conservation and social equity at the community level; and (4) doing comparison effort between Indonesia and Philipina to take a lesson from Philipine experience.  Based on  government policy noted in government rules, the actor who gets role transfer to manage forest resource through society forest is family, whereas a group or cooperation can play role as a place to unite the families power.  The right of society forest which is given for along thirty five years and it can be extended, gives a quite long security to right owner.  But then the realization of the society forest policy is still very small, it has not covered more than 400 hectares of state forest area. The implication from this program to forest resource conservation has not been significant, even it looks inversely that society forest pushses degradation and deforestration.  It happens because the forest areas which are made to be society forest are the forest areas which were farmed out by society for agriculture or plantation in the early time when the national situation were in monetery, economical, and political crisis.  The development of forest management devolution  through CBFM in Philipine is more progressive than society forest in Indonesia.  CBFM in Philipine has reached almost 6 million hectares or 20% from total of state forest area.  The role of president, authorities in DENR area, and local government such as  regency and provincy is very important to realize the devolution of forest resource management to society through CBFM.
