Abstract

Increasing income (INC) is a key variable for the encroacher's self-empowerment in order to able to leave protected forest areas voluntarily when their concessionary period will be due. This urgency is facing by almost Social Forestry Programs across the country such as for Batutegi Lampung Province, whose empowerment period only has 20 years left so that they don't become encroachers again. While physical capital (PC), especially forest land, has seemed leveling off for increasing INC, so the stimulating social capital (SC) is a must. In this context, the role of extension activities (ROLE) in amplifying PC and SC productivity in leveraging INC needs to be elucidated. The objectives of this research are to: (1) reveal the strengths of the direct effect of ROLE on INC, (2)compare the effectiveness of ROLE in leveraging SC to PC in order to increase INC, and (3) evaluate the effectiveness of ROLE in stimulating FC and SC in order to leverage INC. The SEM (structural equation modeling) postulates employed at a confidence level of 95%, where PC and SC are treated as exogenous variables, ROLE as intervening variables, and INC as endogenous variables. The land tenure both inside and outside the forest area is used as an indicator for the PC. Elements of norms, trust, and network as indicators for SC. The three indicators for ROLE employed are the benefit of extension activities about forest protection, agroforestry technique, and post-harvest skill. Two indicators for INC are from coffee beans and other non-timber forest products (NTFP). Data collection was carried out in between April to June 2020 through semi-structured interviews with 98 forest encroachers who were drawn using stratified random sampling. Conclusion: (1) FC and SC not directly productive, did not significantly increase INC (P=0.740 and 0.123 respectively), and in contrast to ROLE were highly productive (P=0.000), (2) PC was also not significantly stimulated to ROLE (P=0.112) but SC was significant (P=0.000) and [3] for PC the ROLE activities were blunt or not significant in amplifying INC (P=0.188) but very powerful or significant for SC (P=0.000). The implication: to ensure that encroachers or HKm land concession holders are able to leave protected forest areas voluntarily when their concession rights expire, the FMU authority must increase the knowledge and skills of HKm concession holders through strengthening extension performance (ROLE) as a necessary condition for increasing income, not continuing to increase the land allotment.

Abstract

The extraction method plays a crucial role in obtaining high-quality DNA samples, which is indispensable for various molecular biology techniques and analyses, enabling a deeper comprehension of genetic information and biological processes. The objectives of the study were: a) to optimize the chloroplast DNA extraction protocol by comparing modified CTAB methods and GeneAid for both leaf and wood samples of Shorea leprosula, a major commercial timber species, and b) to identify a suitable cpDNA region that exhibits variability and universality across taxa. Total DNA was analyzed by gel electrophoresis followed by Sanger sequencing to determine the amplification success. The results revealed that trnL intron, trnL-trnF, and trnG yielded readable sequences of the expected length (maximum 586 bp, 480 bp, and 908 bp, respectively), while the rps 16 intron failed to assemble a contig. The petL-psbE region provided long readability for reverse sequences (769 bp) but not for the forward sequence (195 bp). Higher successful DNA extraction was achieved from the leaves compared to the woods. The lower sequencing quality may be attributed to suboptimal primer design, the structural features of the regions resulting from extensive repetitive sequences, and the suboptimal condition of the extraction method in eliminating wood chemical compounds.

Abstract

Risk management literacy is very important in influencing an individual's decision-making when taking preparatory steps to handle the anticipated risks. This includes oil palm smallholders who are constantly exposed to various types of risks. Therefore, this study aims to analyze the level of risk management literacy among oil palm smallholders in Malaysia. The data of the study was obtained from the online questionnaires distributed to oil palm smallholders using a random sampling method. The data obtained from the final sample of 200 smallholders were analyzed to examine the level of risk management literacy among palm oil smallholders using mean score analysis. The results found that the risk management literacy level among oil palm smallholders in Malaysia is at a moderately high level. Furthermore, mean score for the preference of saving instead of expenditure was the highest i.e. 4.40, indicating that smallholders possess high awareness on the importance of saving as one of the tools for risk management. The study’ findings allowed relevant authorities to formulate new programs such as training and awareness campaign of risk management, on continuous basis. It could assist smallholders to prepare for any potential risks and subsequently be able to create sustainable sources of income.

Abstract

In hillside watersheds, forests play a crucial role in protecting against soil erosion. Not only does forest vegetation cover serve as a biological measure to prevent soil erosion, it also generates income through sustainable management practices. However, there is a scarcity of research that evaluates and compares the profitability of perennial woody crops with that of other agricultural crops by integrating biological aspects within an economic analytical framework in Central Madagascar. In this study, we address this gap by combining a biological growth model that captures complex forest dynamics with economic management data to utilize the discounted cash flow method. We applied this approach to evaluate and compare the profitability of forest management and agricultural crop production in the hillside watershed areas of Central Madagascar, which have experienced severe human-induced soil erosion. Although our results showed that timber production is a profitable option, other agricultural crops generate much higher profits, indicating that financial subsidies alone may not be enough to shift land use toward perennial woody crops. In addition, growing fruit trees such as oranges and mangoes appears to be a much more financially attractive option for local farmers than annual agricultural crop production.

Abstract

Agroforestry-integrated community forests foster greater plant diversity compared to conventional agriculture, potentially offering significant ecological and societal benefits. However, the specific contribution of diverse floor vegetation within these forests to carbon cycling remains understudied. This study addresses this knowledge gap by comprehensively analyzing the floristic composition and carbon storage potential of floor vegetation in tropical community forests. Using a stratified random sampling design with quadrats to ensure representative data collection across various locations in Ciamis Regency, West Java, Indonesia, we identified 296 plant species belonging to 89 families. Our analysis revealed that the understory vegetation exhibits moderate species diversity and stores carbon ranging from 0.107 to 0.238 Mg C ha⁻¹, with an average sequestration potential of 0.730 Mg C ha⁻¹. These findings suggest that community forests harbor diverse floor vegetation communities with significant carbon storage and sequestration potential, providing valuable insights for environmentally sustainable community forest management and contributing to broader efforts towards climate change mitigation.

Abstract

One of the main species in community forests is betung bamboo (Dendrocalamus asper). Optimizing land use under bamboo can be achieved by cultivating food crops. This research aimed to determine the growth of betung bamboo and the production of food crops. The experimental design used a split plot design with four cultivation patterns as the main plots: agroforestry bamboo pattern i.e. agroforestry bamboo + rice (P1), agroforestry bamboo + rice + cassava (P2), agroforestry bamboo + rice + taro (P3), and mixed food crops (rice + cassava + taro) (P4), while the subplots were rice varieties: rindang 2 (V1), protani (V2), and unsoed (V3). The observed parameters were bamboo growth, soil fertility, and food crop production. The results showed that seven-year-old betung bamboo had an average of 6.01 mature stems per clump, an average plant height of 7.23 m, and a stem diameter of 7.12 cm. The numbers of young stems and shoots per clump was 1.45 and 3.71. The highest betung bamboo growth was in the agroforestry pattern (length: 8,49 m, diameter: 7.17 cm, thickness: 1.95, total weight: 21.31 kg). The highest rice yield was observed in the P2V1 treatment (4.17 kg). The highest cassava tuber yield per plant was observed in P4 (2.12 kg). The taro tuber yield was relatively higher in the agroforestry pattern with a distance of >1 m from the bamboo clump (0.52 kg plant-1). The land equivalent ratio (LER) and area time equivalent ratio (ATER) of bamboo and food crop agroforestry have a value above 1, so it is more efficient in land.

Abstract

Urban forest management is crucial for urban development, significantly contributing to environmental, economic, and social well-being. Dolok Sanggul District, in Humbang Hasundutan Regency, offers a unique context for examining technical and sociocultural aspects of urban forest management. This research aims to analyze these aspects' influence on urban forest management in Dolok Sanggul District using a quantitative research method and multiple regression analysis. The study's results indicate that both technical and sociocultural aspects significantly impact urban forest management. Technical aspects, such as law and regulation regarding forestry, account for 51.0% of the influence. Sociocultural aspects, including community opinions on community awareness and participation, education and the social environment, as well as community interaction, contribute 55.2%. Combined, these aspects exert a synergistic effect, with a total influence of 63.4% on urban forest management. These findings underscore the importance of integrating technical and sociocultural considerations to develop effective urban forest management strategies. By leveraging the strengths of both aspects, policymakers and urban planners can create sustainable and resilient urban forests that benefit the community and environment. Additionally, this research highlights the need for a holistic approach that values community input and technical expertise, ensuring balanced and sustainable urban development. This study provides a foundation for future research and practical applications, emphasizing the critical role of comprehensive planning and community engagement in urban forest management.

Abstract

Minister of Home Affairs Regulation Number 52 of 2014 states that the criteria or evidence that must be met for recognition of indigenous peoples are: indigenous history, customary territories, customary law, customary objects, and customary institutions. Using a case study of the Boti Tribe, the oldest ethnic group on Timor Island, this study aims to collect evidence of the existence of indigenous peoples and their customary territories. This research will focus on verifying evidence of the existence of indigenous peoples using a socio-spatial approach. Our findings show that the Boti indigenous community still exists, with several main evidences of its existence, namely, they have a traditional history in which they were formed from several clans led by the Benu clan; there is a customary area with several use zones of land; there are customary laws that regulate daily life and local wisdom in managing natural resources; and there are traditional practices. Additional evidence was discovered that they manage customary forests sustainably, as evidenced by the consistent forest cover over the last 30 years. These findings can be used to develop academic papers and plans for regional regulations concerning the Boti Tribe's recognition.

Abstract

Human-wildlife conflicts present significant challenges in conservation efforts. This study delves into the effectiveness of crowdfunding, intervention mechanisms, and communication initiatives in addressing the human-wildlife conflict, specifically concerning the sumatran tiger. By leveraging data from NGO web platforms, exploratory documentation, national records, and a broad spectrum of literature reviews, we aimed to unravel the nuanced dynamics of these initiatives in the conservation framework. Our findings indicate that while crowdfunding platforms such as the sapu jerat campaign offer innovative fundraising avenues, the harmonized efforts of communication strategies and robust intervention mechanisms create lasting impacts. This study underscores the essence of multifaceted approaches, stressing the value of stakeholder collaborations, including NGOs, local communities, and governmental agencies. Furthermore, this research accentuates the increasing role of digital tools in enhancing conservation efforts, suggesting a paradigm shift in contemporary conservation strategies. Hence, this study offers invaluable insights for conservationists, decision-makers, and NGOs aiming to optimize their strategies in the context of human-wildlife conflicts. At a more detailed level, the intervention mechanisms of the Sumatran Tiger Project demonstrate the importance of adaptive management, inter-agency collaboration, and sustainable financing as key components. This study highlights that the combination of technology, community involvement, strategic planning, and effective storytelling can provide a sustainable future for the sumatran tiger.

Abstract

Forest fires pose an escalating threat, demanding effective communication strategies for communities. While past research underscores the importance of community involvement and transparent communication, the dominance of social media in today's media landscape calls for a reassessment. This study investigates the utilization of social media, specifically Facebook, by the Oregon government during the 2022 fire season in Cedar Creek and Double Creek regions. Through Facepager, 4576 posts and comments were collected and then analyzed using the multi-coder approach and Vader Algorithm focusing on post frequency, thematic content, and user sentiments. The result reveals that positive sentiment polarity scores were observed with 0.61 and 0.71 for Cedar Creek and Double Creek respectively, however, the thematic and post-frequency analysis suggests a need for government agencies to diversify content, emphasizing scientific aspects and addressing community concerns. The findings offer valuable insights for enhancing risk communication strategies, promoting informed public engagement, and guiding effective government communication in wildfire scenarios.
