Land cover change may cause change on the hydrological function of an area, particularly on the distribution of rainfall that reach land surface. This study describes the characteristic of stemflow occurred within 4 ecosystems in Jambi, namely logged forest, jungle rubber, rubber plantation, and oil palm plantation. The main objective of the study was to measure the variability of stemflow in those 4 ecosystems. The main data used were rainfall and stemflow data that were directly measured for 5 months. The derived regression equation model showed that stemflow increase with rainfall depth. It was shown that values of stemflow amongs plantation types was varied indicated by the difference of its regression coefficients, as well as variations of the rainfall at the same transformation type. The percentage of stemflow to rainfall was ranging from 0.04–0.21% for rubber, 0.10–0.38% for jungle rubber, 0.28–0.54% for forest, and 0.84–3.07% for oil palm. The oil palm provided the highest stemflow volume compared to other land cover type. The uniqueness of oil palm canopy may cause the drainage of water from the canopy to the main stem that indicated by highest stemflow funneling ratio value. Rainfall significantly affected the amount of stemflow compared with the characteristics of the plant.

Motor-manual logging has been considered as the most dominant logging system in Java Island, Indonesia. The system-which consisted of felling, delimbing, bucking, hauling, and transporting activities- involves a combination of stress factors e.q. difficult work postures, generation of force, and lifting techniques. In the other hand, combination of the three is well associated with high risk of work-related musculoskeletal injuries (MSIs), including musculoskeletal disorders. This research aimed to assess difficult work posture on felling, delimbing, bucking, and manually short wood hauling by employing rapid entire body assessment (REBA) technique and muscular pain scoring based on the worker's perceive. It was revealed that felling and manual hauling were scored 4 in the REBA action level, indicated very high MSIs risk level, and categorized as “necessary now” for an injury risk preventive action. The workers' pain scoring indicated that low back (spine in general) disorders resulting in low back pain has been considered to be the one of the leading safety issues in the felling and manual hauling. Regardless to complex mechanism of how the personal risk and environmental factors associated with manual material handling injuries, job-related factors approach should be underlined in the MSIs prevention initiative in motor-manual logging.

Overcoming the problem of resource management which relies only on social dimension without understanding the ecosystem dynamics will not be sufficient to create sustainable management. Therefore, socio-ecological system (SES) is needed to respond changes so that robust management could be created. Research on SES was focused more on capacity of governance in creating management of conservation area, particularly in the period where there were occurrence of resistance between social problem and ecosystem. Principal component analysis explained 76% of the total variability. Very high variable respond category occurred on first principal component (PC) with positive effect which was related directly to ecological condition, and negative effect toward catch yield and utilization of traditional zone. Condition of economy and fish resources contributed positively toward second PC, and can be expressed as factor which affected economic condition of fishermen household. Condition of fishermen, related with catching activity and income of fishermen household gave positive effect toward the third PC, and can be expressed as component which affected catching effort and explained exploitation level by fishermen toward resources. Interaction between factors which formed SES occurred due to economic activity of fishermen household, catching efforts, and ecological capacity. Design of governance could be conducted on increase of fishermen household economy through control of catching efforts and considering the carrying capacity and ecological capacity.

Mangrove forest in the context of climate change is important sector to be included in the inventory of greenhouse gas (GHG) emissions. The present study describes land-use and land-cover change during 2006–2012 of a mangrove forest conservation area, Karang Gading and Langkat Timur Laut Wildlife Reserve (KGLTLWR) in North Sumatra, Indonesia and their implications to carbon dioxide emissions. A land-use change matrix showed that the decrease of mangrove forest due to increases of other land-use such as aquaculture (50.00%) and oil palm plantation (28.83%). Furthermore, the net cumulative of carbon emissions in KGLTLWR for 2006 was 3804.70 t CO2-eq year-1, whereas predicting future emissions in 2030 was 11,318.74 t CO2-eq year-1 or an increase of 33.61% for 12 years. Source of historical emissions mainly from changes of secondary mangrove forests into aquaculture and oil palm plantation were 3223.9 t CO2-eq year-1 (84.73%) and 959.00 t CO2-eq year-1 (25.21%), respectively, indicating that the KGLTLWR is still a GHG emitter. Mitigation scenario with no conversion in secondary mangrove forest reduced 16.21% and 25.8% carbon emissions in 2024 and 2030, respectively. This study suggested that aquaculture and oil palm plantation are drivers of deforestation as well as the largest of GHG emission source in this area.

Changing policies over timber supply and its potential impacts to the furniture industries of Jepara, Indonesia Dodik Ridho Nurrochmat; Efi Yuliati Yovi; Oki Hadiyati; Muhammad Sidiq; James Thomas Erbaugh

Though some scholars argue that Indonesian wood furniture industries are in decline, these industries remain a driving force for regional and national economies. Indonesian wood furniture has a long value chain, including: forest farmers, log traders, artisans, and furniture outlets. In Jepara, Central Java, wood furniture industries contain significant regional and historical importance. Jeparanese wood furniture industries demonstrated great resilience during the economic crisis in the late nineties. Although they were previously able to withstand the pressures of economic crisis, the enactment of Minister of Forestry Regulation (MoFor Reg.) 7/2009 on wood allocation for local use -as one of the implementing regulation of decentralization law 32/2004- causes a potential reduction of wood supply to Jepara. Since September 30th, 2014, however, the constellation of domestic timber politics has changed due to the new decentralization law (23/2014), which shifted most regulations on forest and forest products from the regency to the province. This study evaluates the dynamics of decentralization policy on timber allocation and examines the power of different stakeholders given the changing regulation and its consequences for Jeparanese wood production.

The rural forestry business had shown a good economic feasibilty and worthed to develop in the rural economy. However the business income cannot to improve the standard of living worthy and have a low attractiveness. The attractiveness increase can be done with increasing profitability of rural forestry business and enhance the role of forestry graduates. Forestry graduates in Indonesia, with their title as Sarjana Kehutanan (S.Hut) had been scarcely involved in rural and traditional forestry based business. Such anomaly had not been becoming neither governmental nor profesional concerns. This study tried to explore the perspective of the S.Hut, concerning their understanding and interest in the business, to see how far their potential capacity to be entrepreneurs. This study differentiated the respondences into S.Hut working in forestry and S.Hut working in non-forestry job. With qualitative and quantitative approach, and total respondents of 158 persons, consisting 122 persons as forestry jobs and 38 persons as non-forestry jobs, this study found out that the S.Hut in Indonesia had ample or good perspectives based on the parameters of higher interests, attractiveness, knowledge, and effications. It meant that they were worthed to be involved as the business entrepreneurs.
