Abstract

Humans control their cultural environment, which is associated with biotic and abiotic environments, resulting in environmental sustainability. The indigenous community's existence in managing environmental resources must be examined more deeply from the perspective of human ecology. Therefore, this research aimed to examine and analyze the management of resources and environment, mainly the customary forest in the Tenganan Pegringsingan indigenous community. This research employed a participatory observation and spatial ethnography paradigm to understand the pattern of the Tenganan Pegringsingan customary forest management based on customary law (awig-awig), legal delegation (The Customary Forest Decree), and the access of stakeholders to the customary forest. The customary forest governance involved krama desa, the land inheritance rights owners of the Tenganan Pegringsingan indigenous community, and Penyakap, immigrants/krama sesambahan tillers in the customary forest. These three stakeholders had different spatial access to the customary forest as a place and a space.

Abstract

Gunung Merapi National Park (GMNP) is an inseparable conservation area from the surrounding community, as the buffer village community has used its existing forest resources. Therefore, this research aimed to identify the forest resources used by the buffer village community and assess the economic benefit value generated by GMNP. The economic benefits evaluation adopted the direct use value approach and market prices. The results showed that the community used water, firewood, grass, land, and sand. Utilization was conducted in utilization, traditional, and rehabilitation zones. These resource utilizations generated a value of IDR426,230,560,828/year, significantly contributing to the welfare of the buffer village community.

Abstract

Healing forests maintain health through preservative practices, allowing benefits to emerge when site conditions support the practices. Therefore, this research aimed to identify the biophysical components and physical elements of the healing forests in Bunder Grand Forest Park (GFP). This research adopted observation methods and spatial analysis to characterize the healing forests' biophysical components and physical elements. The results showed that Bunder GFP had a diverse biodiversity and a distinctive landscape with the potential to provide comfort for visitors. It also met the criteria outlined in SNI 9006:2021, with medium thermal comfort levels. This research suggested vegetation enrichment to enhance the park's therapeutic potential, decrease noise, and increase thermal comfort. Additionally, the existing water features, karst rocks, and mixed forest vegetation can be used as media for sensory stimulation, further supporting health therapy.

Abstract

Sustainable forest management encompasses a holistic approach that considers forests' ecological, social, and economic functions. However, an increasing focus on economic functions often leads to the neglect of social and ecological aspects. Consequently, it is essential to evaluate community satisfaction regarding the service performance of forest management units (FMUs). This research aimed to assess community satisfaction with the service performance of Unit X KPHL Batu Bara, which oversees coastal forests primarily comprised of mangrove ecosystems in the coastal regions of Batu Bara Regency, North Sumatra, utilizing Importance Performance Analysis (IPA). The findings revealed that the service performance of Unit X KPHL Batu Bara falls short of community expectations, as indicated by a negative average gap score of -0.716 between service performance and expectations. The categories of assurance and tangibles exhibited the highest gap scores. Therefore, Unit X KPHL Batu Bara must enhance their service quality for the local communities.

Abstract

In order to effectively achieve the objectives of local collective action, institutions must establish guidelines that align with community norms and are supported by organizational incentives and sanctions. This study aims to examine the dynamics of property rights over forest resources and the efficiency of local institutions in managing the Nambo Community Forest (HKm) within the Toili Baturube Model Production Forest Management Unit. Employing a qualitative case study approach, data collection methods include document analysis, in-depth interviews, and observations. The findings reveal that the forest status in Nambo District shifted to state ownership post-HKm policy implementation and Law 23 of 2014, leading to changes in community access rights. Additionally, community forest management is facilitated through collaboratively developed policies and agreements evaluated using the Ostrom principle design. The study underscores the importance of comprehensive strategies involving cooperation among regional authorities, local communities, and stakeholders to effectively manage shared resources like community forests. Strengthening institutional capacity, empowering local communities, and fostering collective action can enhance the sustainability and success of shared resource management initiatives.

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

Tingi (Ceriops tagal) becomes one of the natural dyes used in textile dyeing. Ultrasonication is an extraction method that requires less time than conventional methods. Therefore, this study aimed to determine the effect of the ultrasonication duration (20, 40, 60, 80, and 100 minutes) on the total phenolic content (TPC), total flavonoid content (TFC), and total tannin content (TTC). The extraction yield was calculated by drying the solution with a freezer dryer, and phytochemical content was determined using UV-vis spectrophotometry. The results indicated that the yield value of the duration treatment was in the range of 3.74% to 5.53%, which was lower than the conventional method (10.58%). However, TPC, TFC, and TTC had more optimal values than the conventional method, with TPC values ranging from 268.1 to 314.1 mgGAE/g sample, TFC ranging from 68.3 to 87.1 mgQE/g sample, and TTC ranging from 244.8 to 338.1 mgTAE/g sample. The highest compound content was observed at 20 minutes, indicating that the ultrasonication method can be applied to extract Tingi bark as natural dyes.

Abstract

Honey has numerous benefits and considerable potential for development within the Social Forestry Business Group (KUPS). In 2020, honey consumption in Indonesia increased to 60 grams per capita per year, leading to growth in the honey bee business. However, more research is needed to be done on developing business strategies for KUPS in North Sumatra Province. Therefore, this research aimed to formulate development strategies for the honey bee business in Situak Ni Loba Siarsikarsik KUPS, Toba Regency, using the Business Model Canvas (BMC) method. This descriptive qualitative research collected data through direct observation, interviews, discussions, and literature research to map the business model through the nine main elements of BMC, namely customer segments, value propositions, channels, customer relationships, revenue flows, main resources, activities, partnerships, and cost structure. The best strategy identified was to increase the value proposition, expand the strategic partner network, and improve market access. The findings highlighted the need to determine the specialty of the honey produced by the KUPS compared to other products, find cooperation partners for investment, and utilize technology and marketplaces to expand market share.
