Ruteng Mountains in Indonesia are inhabited by people from the tribe Manggarai. Local culture of Manggarai community has a role to conservation and it needs to be integrated in the conservation of natural resources. Where conservation is defined as the management of the sustainable use of natural resources, the integration of local culture into conservation will open up a space of the emergence of the creativity and innovation in solving problems of forest conservation. This study aims to explore and describe to what extent the culture of Manggarai contributes to conservation activities in the protected areas and the possibility of the culture to be integrated within conservation policy. The study employs a qualitative research through ethnographic approach. The qualitative data in 2014 was obtained through field observation, interviews, data from relevant agencies, and related literature. The study shows that the Manggarai community has practiced conservation values, norms, and tradition since hereditary. Manggarai culture related to conservation could be integrated into the activities of the protection, preservation, and sustainable use of natural resources.

The existence of third-party forest and timber certification schemes in Indonesia has created benefits and challenges, mainly for forest industries. In the end, the interests and objectives of those industries will determine whether they decide to get certified and if so, what certification schemes they will use. This study analyses the stakeholder recognition of the competing forest legality and sustainability certification systems and describes the preferences for particular schemes based on stakeholder interests. Online questionnaires were distributed to relevant stakeholders, namely logging companies, wood processing industries, wood processing associations, auditors, academics, environmental organisations and government officials. The results indicate that there are different scheme preferences based on the stakeholder's interests. Sistem verifikasi legalitas kayu (SVLK) is the most frequently preferred scheme due to the simplicity of its requirements and the low cost of its certifying process, while the Forest stewardship council (FSC) is valued for its reputation and very high standards. Furthermore, lembaga ekolabel Indonesia (LEI) was least preferred because of its complexity and because it was unpopular with foreign end buyers, and the programme for the endorsement of forest certification (PEFC) was identified as being a complex scheme that was expensive and subject to high standards, and also appeared to have the least demand. Each scheme should be improved based on stakeholders' expectations, that their popularity with end buyers of timber products should be improved, and that this should be done in a way that allows logging and wood processing industries to choose freely the scheme that is most advantageous to them.

Performance assesment includes the quantity and quality measurements of individual or group works within organization in carrying out duties and functions. It is based on norms, standard operational procedure (SOP), and specified criteria in an organization. Factors affecting quality and quantity of individual performance in an organization are skills, experience, ability, competence, willingness, energy, technology, leadership, compensation, clarity of purpose, and security. This study aims to identify and analyze the performance of forestry human resources (HR) related to licensing forest utilization, releasing forest area, and leasing forest area. The results of the study are: (1) the performance of forestry HR in licensing forest utilization was relatively still poor; (2) the structure (rules, norms, cultural cognitive) of forestry HR was unclear and is not well developed; and (3) the culture of learning organization, including personal mastery, mental models, shared vision, team learning, and system thinking is still insufficient and needs to be developed at the ministerial, provincial, and district/city levels. Some suggestions for improving the performance of forestry HR are: (1) establishing an appraisal team/task force of forestry HR performance; (2) developing commitment for high quality service at the bureaucratic elites and their highest level networks; and (3) considering the development of one stop licensing supported by online system to promote transparency and public accountability.

This study evaluates the compatibility of scientific voices with the needs to combat forest fire as perceived by relevant stakeholders through a review of scholarly output, an evaluation of the conformity between scientists and stakeholder views on forest fire issues, and an analysis of how different types of scientists and voice channels contribute the local needs to combat forest fire in Indonesia. This research indicates that although forest fire has cross-country border impacts, forest fire discourses were dominated by home country issues rather than the concerns of global forest fire events. Further, although information about forest fire is widely available in the scientific journals, the “knowledge utilization” of this information remains low. To improve “knowledge utilization”, scientists can use different channels to disseminate information, in addition to scientific journals. While social-economic aspects are perceived to be the prime problem of forest fire in Indonesia, the minimal presentation of social scientists within forest fire discourse is a concern. To address these primary concerns within and outside scientific journals, the involvement of social scientists within the forest fire discourse is very important.

Seed deterioration is the process of deteriorated seed in view of viability that changed the physiological and chemical content. The aim of this research is to find out the effect of moisture content and storage on viability and biochemical content of jabon putih seed. Completely Randomized Design was used for decreasing moisture content based on seed drying time for 0, 24, 48, 72, 96, 120 hours, and Completely Randomized Factorial Design was used for the combination of moisture content (drying time for 0, 24, 48, 72, 96, 120 hours) and room storage (ambient room, air-conditioned room, refrigerator). The results of this research are: (1) seed drying time and seed storage affected the change of seed viability and biochemical content, (2) seed drying time and seed storage influence significantly the value of moisture content, germination percentage, and biochemical content (lipid, carbohydrate, protein), (3) The longer time of seed drying and seed storage has decreased the seed moisture content, germination percentage, and the carbohydrate content, but it has increased the content of lipid and protein, and (4) the seeds were stored in refrigerator has better viability compared to dry cold storage and ambient room.

High rate of deforestation occurred in Sumatra Islands had been allegedly triggered by various factors. This study examined how the deforestation pattern was related to the typology of the area, as well as how the deforestation is being affected by many factors such as physical, biological, and socio-economic of the local community. The objective of this study was to formulate a spatial model of deforestation based on triggering factors within each typology in Sumatra Islands. The typology classes were developed on the basis of socio-economic factors using the standardized-euclidean distance measure and the memberships of each cluster was determined using the furthest neighbor method. The logistic regression method was used for modeling and estimating the spatial distribution of deforestation. Two deforestation typologies were distinguished in this study, namely typology 1 (regencies/cities with low deforestation rate) and typology 2 (regencies/cities with high deforestation rate). The study found that growth rate of farm households could be used to assign each regencies or cities in Sumatra Islands into their corresponding typology. The resulted spatial model of deforestation from logistic regression analysis were logit (deforestation) = 1.355 + (0.012*total of farm households) – (0.08*elevation) – (0.019*distance from road) for typology 1 and logit (deforestation) = 1.714 + (0.007*total of farm households) – (0.021*slope) – (0.051*elevation) – (0.038* distance from road) + (0.039* distance from river) for typology 2, respectively. The accuracy test of deforestation model in 2000–2006 showed overall accuracy of 68.52% (typology 1) and 74.49% (typology 2), while model of deforestation in 2006–2012 showed overall accuracy of 65.37% (typology 1) and 72.24% (typology 2), respectively.

Forestry sector is the biggest carbon emission contributor in Indonesia which is mainly caused by deforestation. In Kalimantan island one of the largest island in Indonesia has a significant area of forest cover still can be found although an alarming rates deforestation is also exist. This study was purposed to established spatial model of deforestation in Kalimantan island. This information is expected to provide options to develop sustainable forest management in Kalimantan trought optimizing environment and socio-economic purposes. This study used time-series land cover data from the Ministry of Environment and Forestry (2000 – 2013) and is validated by SPOT 5/6 images in 2013. The spatial model of deforestation were developed using binary logistic. The results of logistic regression analysis obtained spatial model of deforestation in Kalimantan = 1.1480714 – (0.033262*slope) – (0.002242*elevation) – (0.000413*distance from forest edge) + (0.000045*Gross Regional Domestic Product). Validation test showed overall accuracy about 79.64% and 77.01% for models of deforestation in 2000–2006 and 2006–2013 respectively.

The Periodic comprehensive forest inventory (Inventarisasi Hutan Menyeluruh Berkala called IHMB) is Indonesian forest stands inventory were based on compartment at forest effective area of forest management unit (FMU). To preserve sustainable forest management, IHMB implementation are used as a benchmark on the determinate of maximum cutting area and large of timber volume that can be produced by FMU to preparing long-term forest planning. The purpose of this study is to assess the suitability and accuracy of the IHMB implementation results to arranging forest management plan that aims to produce sustainable timber. Data gathered with direct observation on FMU (PT. Bts and PT. SMS) in Papua Province. Data analysis using descriptive statistic method and the sampling is using purposive sampling method. The study showed that the data and information collected in accordance with IHMB guidelines have not covered all the necessary data to arranged forest management plans based on the sustainability forest principles to appropriate with the criteria and indicators of sustainability. IHMB Implementation is the important activity on FMU. The sense of word “comprehensive” on IHMB is meaningfully only covered the forest area, without including all components of the data and information on forest ecosystem..

Forest resource management has a characteristic of high transaction cost particularly due to lack of valid information and policy process. Such characteristic requires unique institution to ensure an effective policy implementation. This study shows that state has inadequate control over forests and forest governance, extra-legal access, as well as patron-client relationships as the causes of the high transaction costs. Consequently, more and more the natural production forests are degraded and this does not only cause loss of state revenue from natural resources, but also a bankruptcy of corporations which exploit natural production forests. Most of those natural forest assets turned into resources for producing and reproducing a rival institution or extra-legal power, rendering official state institutions incapable of controlling transaction costs. Therefore, changes and improvements of the licensing arrangements need to be supported by the political elites and elite government officials in order to break the historical influence as well as to serve as a new platform for mid-level employees and government officers in implementing the national forest utilization policy.

Fungal endophytes are fungi that lives within plant tissues without causing apparent disease. It is also suggested that these fungi have ability to enhance plant growth and plant resistancy against pest and disease. This research is a preliminary study about root fungal endophytes in dipterocarp since there are lack research concerning about this study focus. We examined root fungal endophyte isolated from seedling of Shorea leprosula and Shorea selanica taken from Dramaga Experimental Forest, Bogor. Furthermore, we also tried to find out the fungal potential ability to solubilize phosphate and suppres fungal pathogen by in vitro assay. Surface sterilization method was used to isolated fungal endophytes from root tissues. Trichoderma spirale, Velsalceae sp., Melanconiela ellisii, Chaetosphaeria callimorpha, and Trichoderma asperellum were isolated during this study. These fungi appear to have specific association between fungal species and host plant, but no evidence of fungal order-level specificiation in S. leprosula and S. selanica. In vitro test also suggested that root fungal endophyte Trichoderma spirale and Melanconiella elisii have potential ability to solubilize inorganic phosphate. In addition, this result also present that root fungal endophyte T. spirale and T. asperellum have the potential to inhibit pathogen fungi Fusarium sp.
