The Social Forestry Program was a government initiative that yielded significant outcomes and provided unprecedented access and opportunities to the community. One notable change has occurred in the Perhutani area through a scheme known as IPHPS. This scheme provides long-term tenure security to forest farmers with higher returns than before. In addition, extensive experience in addressing tenure conflicts in the Perhutani area, a State Forestry Corporation (SFC), has prompted communities to apply for the IPHPS scheme. Therefore, this research aimed to investigate the dynamics of changes in access and assess their implementation using the concept of property rights as a framework. The results showed that the IPHPS scheme provided community groups the right to manage forests but needed more flexibility to decide on the use of resources. In addition, the management patterns regulation had a significant responsibility to restore forest conditions. Furthermore, this research proposed new rights, particularly management rights, for community groups to manage their forest resources up to the operational level and improve forest conditions. In addition, the absence of a management authority caused difficulties in achieving social forestry's objective of increasing local communities' role in managing their forest resources.

This research analyzed the sengon (Falcataria moluccana Miq.) seedling production risk and factors associated with the risks at the Research and Development Center for Forest Plant Seed Technology (BPPTPTH) Bogor. The data collection included interviews using questionnaires with 11 purposely selected respondents. This research employed the Fault Tree Analysis (FTA), a descriptive qualitative method, to analyze the seedling production risks. The results revealed two groups of risks, namely field and management production risks, that stemmed from eight primary roots. These eight primary roots included long seed storage time, far distance between the nursery and the researcher's office, lack of safety facilities, lack of employee skills, lack of employee appreciation, high frequency of employee absences for personal reasons, changes in seasons that cause changes in planting schedules, and changes in budget allocation. Inaddition to these eight main factors, leaf aphids and fungi attacks, including tumorrust(karat puru), could also increase seedling production risks.

Mapping forest fires became one of the efforts to reduce the fire vulnerability. Spatial model development for fire vulnerability could employ a GIS-based information value model (IVM) that excels in predicting vulnerability by leveraging hotspot inventory data. However, this model remained relatively unexplored. This research aimed to develop a fire vulnerability model of peatland-dominated areas in West Kalimantan Province and identify biogeophysical factors that significantly influence fire vulnerability in the research area. The IVM employed hotspots, accessibility, land cover, distance to settlements, distance to rivers, soil types, peat types, and Normalized Difference Vegetation Index (NDVI) parameters. The results revealed that the medium hazard class dominated forest and land fire vulnerability in West Kalimantan Province (272,663 ha). In addition, the average annual hotspot intensity from 2012 to 2022 negatively correlated with annual rainfall. Factors such as the brackish water topogen peat type, podzolic-cambisol soil type, accessibility, shrub land cover, and NDVI collectively contributed to the high level of vulnerability.

Breeding teak with a clonal system was a common practice to enhance productivity and reduce rotation. A private company in Paliyan Sub-District, Gunungkidul Regency, Indonesia, developed Jati Unggul Nusantara (JUN) through vegetative propagation, particularly cloning, using cuttings. JUN had gained widespread popularity as a replacement for conventional teak varieties for commercial purposes. The utilization of JUN commercial timber left various non-commercial biomass forms, such as leaves, branches, and twigs. This research aimed to assess JUN logging waste biomass's energy potential and characteristics across different tree-age stands. This research used non-commercial biomass from six- and eight-year-old trees, including branches, twigs, leaves, stumps, and unmerchantable top stems. The results showed that the average dry weight of JUN logging waste from six- and eight-year-old trees was 31.5 and 53.5 kg/tree, while the calorific value ranged from 4516.4–5177.7 cal/g. This waste had good characteristics as an energy material, specifically from the part of unmerchantable top stems with a high fuelwood value indexof 6579.6.

The tricolour langur and proboscis monkey in Bukit Semujan cohabited and utilized the same resources. Cohabitation, mainly due to resource constraints, needed substantial attention to ensure the survival of these primates. This research aimed to map the utilization of canopy strata vertical forest structure and vegetation as food sources and identify the size and overlap of ecological niches for both primates. This research occurred in Danau Sentarurn National Park (DSNP) from July to December 2021. The data collection employed the ad libitum method. The results indicated that cohabitation occurred in the canopy strata vertical forest structure utilization, particularly stratum B and C, and was related to food availability for both primates. The Jaccard Index of the stratum utilization association was 0.6 for swamp forests and 0.8 for hillside forests, while the food plant association was 0.2. In addition, the ecological niche of the tricolour langur overlapped 48% against the proboscis monkey and 34% on the contrary. The tricolour langur's niche size (FT) was 0.32278 ≤ 0.5960 ≥ 0.81253, while the proboscis monkey was 0.20866 ≤ 0.52837 ≥ 0.78529 at 95% confidence interval.

The interaction between predators and prey has resulted in population dynamics and played a crucial role in maintaining species' populations within ecosystems. This research aimed to identify distribution and activity patterns to understand prey-predator interactions and the effect of environment and prey density on Felidae presence at Bukit Rimbang Bukit Baling Wildlife Reserve (BRBB WR), as an essential area for maintaining large mammal habitats in Sumatra. The camera traps were systematically placed in the Northeastern part of BRBB WR to collect presence data. The prey-predator interaction analysis used kernel density in RStudio. The effect of environment and prey density on Felidae presence was analyzed using a generalized linear model (GLM). The results indicated that Felidae and prey exhibited a dispersed distribution pattern, showing high activity at night and day, respectively. The Sumatran tiger, clouded leopard, leopard cat, and mouse deer had the highest overlap time (>0.50). However, the environmental and prey density had statistically non-significant effects on the presence of Felidae. Human activities in the area potentially disrupted wildlife community dynamics, although this aspect was beyond the scope of this research. This research suggested further investigation of the effects of human activities on wildlife communities in BRBB WR.
捕食者和被捕食者之间的相互作用导致了种群动态，并在维持生态系统中物种种群中起着至关重要的作用。在苏门答腊岛武吉临邦武吉巴陵野生动物保护区(Bukit Rimbang Bukit Baling Wildlife Reserve，简称BRBB WR)，本研究旨在确定猫科动物的分布和活动模式，了解捕食相互作用以及环境和猎物密度对猫科动物存在的影响。武吉临邦武吉巴陵野生动物保护区是苏门答腊岛维持大型哺乳动物栖息地的重要区域。系统地在BRBB保护区东北部设置了相机陷阱，以收集存在数据。猎物-捕食者相互作用分析采用RStudio中的核密度。采用广义线性模型(GLM)分析了环境和猎物密度对棉铃虫存在的影响。结果表明:蝇类和猎物分布呈分散分布，夜间和白天活动较多;苏门答腊虎、云豹、豹猫和鼠鹿的重叠时间最高(>0.50)。环境密度和猎物密度对Felidae的存在无显著影响。该地区的人类活动可能会破坏野生动物群落的动态，尽管这方面超出了本研究的范围。研究结果表明，人类活动对野生动物群落的影响有待进一步研究。

Comprehensive research was conducted in the mangrove ecosystem of West Muna Regency to investigate the absorption of greenhouse gas (GHG) and degradation of its litter-produced GHG emissions, including N2O and carbon. The ecosystem consisted of four stations, namely Mangrove Maginti (station I), Mangrove Tiworo Tengah (station II), Mangrove Tiworo Islands (station III), and Mangrove Sawerigadi (Station IV). The research aimed to determine emissions and global warming potential (GWP) of N2O gas resulting from the degradation of mangrove litter. The team used a syringe mounted on the hood to collect gas samples and gas chromatography for concentration analysis. The correlation of emissions to environmental variables was analyzed using the Pearson correlation method. The results showed that all species' most significant and smallest average emissions were at stations III and II, with values of 0.0019 mg/m2/hour and 0.0015 mg/m2/hour, respectively. Water temperature showed a weak relationship with N2O emissions, namely r = 0.3511 (p <0.05), while water salinity did not strongly correlate with N2O emissions (r=-0.4471; p<0.05). The average GWP value ranged from 0.3665–0.6314 CO2e mg/m2/hour. Species R. apiculata and B. cylindrica at stations III and II had the largest and smallest GWP values of 0.8392 and 0.1912 CO2e mg/m2/hour, respectively.

The Flores Timur FMU establishment was part of the broader efforts to enhance forest governance, improve management practices, and resolve land tenure conflicts effectively within forest areas. However, the challenges commonly encountered included conflicts with communities and other sectors regarding land tenure, area planning, and policy implementation. This research aimed to identify strategic variables of internal and external factors to determine a development strategy for Flores Timur FMU-Protected using SWOT (strengths, weaknesses, opportunities, threats) analysis. The results showed that the primary strategy for managing Flores Timur FMU included law enforcement for forest protection, acceleration of rehabilitation efforts for forests and lands classified as critical, and calculation of forest economic values based on the benefits of environmental services.
