Abstract

This study examines the cultural characteristics of communities living around the Sirimau Protected Forest and their impact on sustainable forest management. The surrounding indigenous communities hold a deeply rooted cultural system that includes language, knowledge systems, social organization, technology, livelihoods, and religious beliefs, all of which influence their approach to natural resource management. One of the core elements is local ecological knowledge—an understanding of the forest’s ecosystem, flora, fauna, and geography that has been passed down through generations. Key social structures, such as the roles of local leaders (raja), community councils (saniri), and forest guardians (kewang), play a significant role in ecological stewardship through customary regulations, including the sasi tradition, which restricts forest use during specific periods to prevent overexploitation. The research emphasizes the importance of involving indigenous communities in forest management decision-making processes, which not only supports ecosystem sustainability but also preserves the cultural identity and values of these communities. Findings from this study advocate for community-based forest management approaches that integrate social, economic, and cultural aspects to achieve optimal environmental sustainability.

Abstract

The Siak Regency implemented the Green Siak Policy in 2016 to commit to reducing carbon emissions. This research aimed to assess land use and land cover (LULC) changes from 2016 to 2023 and make projections for 2030, quantify carbon stocks by LULC type, and estimate CO₂ emissions associated with the implementation of the Green Siak Policy. This research classified LULC using Landsat imagery. It employed the CA-Markov to project land cover in 2030 using eight driving factors: elevation, temperature, rainfall, population density, distance from roads, burned areas, state forest areas, and evidence likelihood. This research assessed carbon stocks using the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model and calculated CO₂ emissions based on changes in LULC and peat decomposition. The findings revealed a slight reduction in total carbon stock from 1,232.52 MtC in 2016 to 1,232.12 MtC in 2023, with annual CO₂ emissions of 1.4 MtCO₂e. Projections indicated an increase in carbon stock, expected to reach 1,232.27 MtC by 2030, with anticipated annual emissions of 1.398 MtCO₂e from 2023 to 2030. While the Green Siak Policy targeted a decrease in emissions of 23.28 MtCO₂e/year by 2030, the results indicated that the Regency achieved merely 0.03% of its target.

Abstract

Since the establishment of the KPHL Kota Ambon in 2010 until nearly a decade, how has the development been managed? How management performance. Therefore, through this study, the performance of the management of the KPHL Kota Ambon aims to determine the management performance of KPHL Kota Ambon. This research was conducted at the KPHL Kota Ambon, November-December 2019. The research was conducted using Criteria and indicators made by Forest Wach Indonesia ((FWI), 2014), document verification, and in-depth interviews with the Head of the UPTD. Pulau Ambon dan Pulau-Pulau Lease. Quantitative analysis method based on calculation procedures made by FWI, 2014. The index results are then described using descriptive methods. The results of the study concluded that 1) The performance of the management of the KPHL Kota Ambon was in the medium criteria index; 2) Management of KPHL Kota Ambon is not yet optimal because the RPHJP has not been ratified as a basis for the preparation of the RPHJPd and Business Plan; 3) The organizational structure has not been filled and the available human resources are not yet competent in the management of FMUs because they have not attended special education and training on FMU management; 4) KPHL Kota Ambon management activities is still limited to socialization activities that have not been routinely so that not many people know about KPHL Kota Ambon

Abstract

Protected forests are very important to support human life and the environment. One way to determine the condition of protected forests is through land cover. The aim of the research is to determine the condition of the vegetation on the land cover. The research method follows the circular plot method inventory procedure. The data analyzed includes density, the Important Value Index to test the density and level of dominance of vegetation types in an area and the Shannon Wiener Index to test the level of diversity of vegetation types. The highest density value in Primary Dry Land Forest is 15.17% and the Importance Value Index is 69.76%. The density value in secondary dry land forest is 18.37% and the importance value index is 80.02%. The bush density was 25.37% and the important value index was 95.03%. Species diversity in all land cover is included in the medium category with respective values ​​in primary dry land forests of 2.72; secondary dry land forest 2.53 and shrubs 2.07. These three land covers are included in the medium category, which means moderate diversity, sufficient productivity, fairly balanced ecosystem conditions, and moderate ecological pressure.
