Verifying the Existence of Indigenous Peoples using a Socio-spatial Approach: A Case Study of the Boti Tribe, Indonesia
Full text linkMinister 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\u27s recognition.
 
A Comparative Study of the Organellar Genome of Gyrinops versteegii and Aquilaria malaccensis
Full text linkGyrinops versteegii and Aquilaria malaccensis are two important species of the Aquilarieae tribe. The main problem of this tribe is the challenge of species identification that is strongly dependent on the presence of flowers and fruit, which are not always available. The availability of whole genome information is expected to address the problems of species identification. This research aims to construct and compare the chloroplast and mitochondrial genomes of G. versteegii and A. malaccensis from short-read data using the NOVOplasty and GetOrganelle assembler. The chloroplast genome assembly revealed a full-length quadripartite circular structure with sizes of 174.814 bp (G. versteegii) and 174.821–174.822 bp (A. malaccensis), with highly conserved gene and organization. Meanwhile, the mitochondrial genome is multipartite with a size of 400.012 bp (G. versteegii) and 400.000 bp (A. malaccensis), with highly variable genes and organization due to the presence of gene cluster repeats. The LSC/IR/SCC region borders and phylogenetic analysis in chloroplasts indicate variations between the genomes of these two species. The investigation of nucleotide diversity in the chloroplast genome revealed that the trnL-rpl32 region had the highest nucleotide diversity (Pi = 0.03). This information will be useful in the future for a variety of downstream analyses
Technical and Sociocultural Aspects in Sustainable Urban Forest Management in Dolok Sanggul District
No full textUrban 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\u27 influence on urban forest management in Dolok Sanggul District using a quantitative research method and multiple regression analysis. The study\u27s 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
Effects of Peatland Fires on Above-ground Carbon Stocks in Kepulauan Meranti Regency, Riau Province
Full text linkPeat fires substantially alter ecosystem dynamics and carbon storage, making it essential to understand how fire-related components affect post-fire carbon stocks. This study aims to estimate the above-ground carbon stock on burned peatlands in Kepulauan Meranti Regency, Riau Province, and examine how fire recurrence, last fire occurrence, and burn severity influence the carbon stock using a modified regression model and remote sensing data. The normalized burn ratio index difference between post- and pre-fire was used to calculate burn severity. The continuous predictor variable was transformed using a natural logarithm to generate the best-fit model. The 2014 burned peatland stored the highest carbon, whereas the 2020 burned peatland was the lowest. The 2020 fire period was the most severe compared to the 2014 and 2018–2019 fires, although it had a smaller burned area. This study highlights that fire-related components significantly affect post-fire peatland above-ground carbon stocks, particularly last fire occurrence and burn severity. Meanwhile, fire recurrence had the weakest impact and correlation with above-ground carbon stock compared to other predictors, likely due to the brief intervals between fire events in 2018 and 2019, which may have restricted ecosystem recovery and limited carbon storage capacity
Traditional Ecological Knowledge of the Tengger Tribe and its Influencing Factors in Bromo Tengger Semeru National Park
Full text linkAn understanding of the local traditional ecological knowledge (TEK) of a region is crucial to understand the interactions between indigenous societies and their ecosystems. To understand the TEK of Indonesian indigenous people and its influencing factors, we evaluated the Tengger people’s knowledge and conservation awareness regarding culturally important plants (Javanese edelweiss). We interviewed 641 people from seven Tengger villages located adjacent to Bromo Tengger Semeru National Park (BTS), Indonesia. We developed 31 models to examine factors affecting edelweiss knowledge and calculated the Akaike information criterion values to select the best model. Sex, education, and residency duration were significant predictors of edelweiss knowledge. Men, individuals with higher levels of education, and those who had lived in the area for a longer period of time had higher levels of edelweiss knowledge. Our findings confirm that communication within the community and external information sources, such as media and formal education, are involved in knowledge transmission related to edelweiss. Educational activities for local people can be used to disseminate TEK through formal education in schools and informal education programs conducted by the national park managers
Ethnobiology Study: Game in Dayak Lun Dayeh Community at Watershed of Mentarang in Malinau
Full text linkDayak Lun Dayeh is one of local community who lives in East Kalimantan, where they’ve mostly practiced hunting traditionally, has particular ways to find hunting spot and use hunting techniques sustainably. The research about this community was conducted in river bank of Mentarang in order to determine the various kinds of game animal, frequently used hunting ground, and hunting ways of Dayak Lun Dayeh community at two different times, on May-July 2016 and June-August 2021. Research data were collected through open ended interviews (assisted by key informants), field observations and animal photos. Data were presented descriptively by ethnobiology approach. The results showed that this community practices subsistence hunting of wild animals, which comprised of mammals (69-73%), reptiles (14-15%), aves (8%) and amphibians (0-4%). The meat obtained from hunting(s) were consumed as protein source, served as medium in traditional ceremonies or religious rituals based on ancestral teachings. Wild animals such as Cervus unicolor, Sus barbatus, Muntiacus atherodes could be found easily in abpa’ nuvan (salt lick) rather than primary forest, swidden (latii), swidden fallow (included amug, jekau and ripa), farm, river, or secondary forest such as the logging roads of former timber company. Several hunting techniques were applied such as using hunting dogs for tracking the game animals (gelibut), sieging or waiting (gabang) at specific location (abpa’ nuvan), and setting traps (ton)
Ecological Analysis of Community and Private Partnership in Tree Planting Program to Rehabilitate Degraded Lands: A Case Study in East Java, Indonesia
Full text linkCommunity and private partnership (CPP) in tree planting initiative is potential to accelerate rehabilitation of degraded lands. Yet, empirical studies to analyse such programs are limited. Here, we analysed a CPP tree planting program in East Java, Indonesia by focusing on ecological aspects, i.e. vegetation cover changes, floristic diversity, above-ground carbon storage, and soil and microclimate conditions. Results showed that there was a striking increase in vegetation cover, yielding a total carbon sequestration of 3,853 tons, or equivalent to the reduction of 14,140 tons of CO2 emissions. On the other hand, co-benefits in term of floristic diversity at a landscape scale was low, and soil and micro-climate conditions were still marginal. This study provided empirical evidence that collaboration between communities and private entities in tree planting program can be effective in rehabilitation of degraded lands. Improvement in land management systems applied in tree planting through the implementation of mixed gardens or complex agroforestry is suggested if aiming for co-benefits in floristic diversity and soil properties. Our study recommends a broader adoption of a similar scheme in rehabilitation of degraded lands across Indonesia
