Abstract

The impact of access policies on the influx of ignorant behavior in conservation areas is still understudied. This research aims to detect this ignorant tourist behavior in the conservation areas by analyzing perceived accessibility and examining the tourist typologies. The study was conducted in Komodo National Park, one of the most popular destinations in Indonesia, which has experienced high accessibility development. The research method employed tourism policy and factor-cluster analysis to examine the tourist typology. Accessibility constructs and hedonic tourist motivation were used as the variables in the analysis. The total respondents were 534, and the data were analyzed using a non-hierarchical K-means cluster analysis. The result showed that three aspects were considered in managing the accessibility in the conservation areas. The aspects included destination, individual, and conservation accessibilities in the national park. Further, four tourist typologies were found in this research. Two new typologies, hedonistic adventure tourists and high-risk hedonistic tourists, indicated ignorant behavior. Two others, such as real ecotourists and nature-relaxing tourists, presented general nature-based tourist characteristics in the existing literature. The managerial implications of this research are providing practical insights for planners and destination managers to improve conservation awareness for remarkably ignorant tourists.

Abstract

Karst areas in Indonesia are arid landscapes with water-use limitations because of dissolved carbonates. Long-term water scarcity stunts plant growth and often kills them. For tropical karst forestry-greening, the three best legume and three best non-legume species from a previous trial comprising 20 species were compared. Since October 2011, seedlings of the top three non-legume, species Aleurites mollucana, Sterculia foetida, and Alstonia scholaris, and three legume species, Acacia auriculiformis, Cassea seamea, and Acacia mangium, have been grown for four months. In January 2012, field trials were established at two dry karst locations, i.e., Pracimantoro, Central Java, and Bunder, Gunung Kidul Yogyakarta. A randomized block design was used to raise 1.764 seedlings at the two sites with 7×7 plots, 3×3 spacing between trees, and three blocks. After 10 months, legumes and non-legumes differed greatly in all growth parameters. These disparities lasted up to 30 months, when trees should have adapted to their new surroundings. After seven years of planting, legume trees raised the soil's organic matter concentration from low to medium, making it more fertile, similar to soil from intensive agricultural regions. Thus, early or mixed legume plantings on tropical karst sites may aid in better re-greening than the establishment of non-legumes.

Abstract

The Boti indigenous community on Timor Island utilizes non-timber forest products for their daily lives, but there is a lack of information about their potential and sustainable use, which requires an empowerment initiative for them. This study aims to investigate the potential and utilization of NTFPs while also formulating an NTFPs development strategy in Boti Village. A combined method, including literature review, plot measurement, socio-economic surveys, and interviews, was used to collect data. NTFPs were evaluated for their potential using the importance value index; their utilization was studied through an ethnobotanical survey; and an NTFP development strategy was formulated utilizing a SWOT-PESTLE analysis. The results show that three types—candlenut, tamarind, and lac tree—dominate among the 13 species of the NTFPs. NTFPs are used for various purposes, such as medicinal, natural dye weaving, and selling to raise household income. The NTFPs development in Boti village needs to be prioritized, with a focus on increasing the added value of NTFPs through funding, facilitation, technological assistance, planting and preserving, collaborating more, and enforcing formal and customary rules. The results can be used as a baseline or reference for sustainable NTFP management and the empowerment of the Boti indigenous community.

Abstract

The tropical forest plays an important role in ecosystem services, yet anthropological activities have changed the ecological conditions. Thus, this research was designed to reveal the species richness and diversity in secondary forests, including lifeform alteration. The 50 perpendicular plots were placed in both forests, with 25 for each. The study revealed that the secondary forest represents a stage of ecological succession in which species richness and diversity decreased. Additionally, the composition of life forms in the secondary forest changed, with dominant herbs indicating a more dynamic vegetation due to shifting ecological conditions. Species classified as Threatened have disappeared due to human activities in the forest. However, the secondary forest has provided a habitat for certain species, including those with conservation status, such as Threatened or Extinct, to thrive and colonize. Approximately 15.7% of species exclusively thrive in secondary forests, including Antiaropsis uniflora C.C.Berg. Therefore, to promote sustainable forest management, this study suggests monitoring the species in secondary forests, particularly since the use of forests has traditionally been determined by local communities, including in restricted forest areas. Moreover, the local government could officially designate traditional forest use, thereby allowing restricted forests to be conserved as old-growth forests.

Abstract

Peat 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.

Abstract

Work in the forestry sector, especially pine resin harvesting, is classified as heavy work and a high risk of accidents and occupational health because the pine resin harvesting activities are carried out on varying topography, using various heavy tools and hazardous chemicals. Hence, the occupational and safety health management system (OSHMS) is an essential sector. Some studies about pine resin tapping focused on productivity, socio-economics, and resin quality; however, there needs to be more research about OSHMS in pine resin harvesting. Therefore, the effectiveness of implementing OSHMS is essential to analyze, finding out its impact on the rate of work accidents and employee health in forest product harvesting activities. The objectives of this study are a) to identify the sociodemographics of forest employees, b) to clarify the pine resin harvesting activities and identify the hazard risk, and c) to clarify the effectiveness of the implementation of OSHMS on pine resin harvesting activities. The research was conducted in the state forest company (SFC) in Central Java Province. Interview techniques, literature studies from OSH documents, and field observations carried out to collect sociodemographics of forest employees are dominated by old employees, low education levels, and a working system based on family; this situation impacts the implementation of OSHMS and pine resin harvesting. The SFC provides SOP and training about the technical application of pine resin harvesting, but some employees did not follow the procedure. The impact of disobeying employees, the hazard risk, and accidents also improve. The recommendations for the company are to increase the time spent training the workers and to implement the OSHMS standard. Personal protective equipments have to check routines, and the employees must know the mechanism if there is an accident and how to solve it.

Abstract

Monitoring the location and extent of agroforestry land use land cover (LULC) in Lampung Province is critical for effective policy development and sustainable agroforestry management. However, existing monitoring efforts have been limited to small regions. This study addressed this gap by employing threshold values from five distinct vegetation indices (ARVI, EVI, GDVI, NDVI, and SAVI) derived from Landsat 9 OLI imagery to accurately identify and estimate agroforestry LULC across the Lampung Province. The data collection activities were carried out using a combination of Landsat 9 OLI satellite imagery acquisition, and ground truth validation on 7 classes of different land use (forest, agroforestry, dry land farming, ricefield, settlements, bare land, and water bodies) within 5,600 points of interest (POI) inside 5 regencies as an area of interest (AOI). This study aimed to predict agroforestry area based on vegetation indices (VIs) threshold using the decision tree (DT) algorithm. The research process involved a series of systematic steps, beginning with satellite image data acquisition and preprocessing, VIs values extraction, and DT sequential for agroforestry areas. The DT computation incorporated the value of each LULC type on the 5 VIs. The result showed that the overall accuracy reached 91.59% with a Kappa coefficient of 0.89, indicating a high level of accuracy for land cover identification. The DT algorithm calculation showed that the agroforestry in Lampung Province estimated spanned for 734,739.61 ha, determined only by NDVI and ARVI. The findings have significant implications for both policy development and agroforestry management. Accurate LULC classification enhances decision-making processes by providing reliable data on land use patterns, which can guide sustainable land management practices and support the creation of region-specific agroforestry policies. This research directly informs policymakers on the extent and distribution of agroforestry areas, offering a foundation for crafting strategies aimed at promoting sustainable land use while mitigating environmental degradation. The methodology also provides a scalable approach for other regions facing similar agroforestry and land management challenges.

Abstract

Gyrinops versteegii, belonging to the Themelaeaceae family, is one of the species producing high-grade agarwood. The induction technique can accelerate the agarwood product. This study inducted the G.versteegii tree with fungal species, a variation of hole position, and an induction technique. The research was done at a domesticated G. versteegii plantation in Sragen and Karanganyar District, Central Java Province. The agarwood quality resulted from the inoculated G.versteegii tree characterized by the wood aroma, the discolouration area, wood aroma, and terpenoid content, is significantly affected by the wood position in the stem, the fungal species, and the inoculation technique. The upper stem results the better agarwood than the bottom stem. Using the inoculant of the Fusarium oxysporum can achieve better agarwood than the inoculant of F.solani and mixed F.solani x F.oxysporum. Furthermore, the infusion technique gains a better agarwood result than others. Keywords: domesticated G.versteegii, wood aroma, discolouration, and terpenoids.

Abstract

Natural resource management and biodiversity protection in conservation areas require the involvement of local communities. However, these efforts are often hampered by conflicts in the use of resources among the population, including among the indigenous people. In this regard, this study examines the contestation of the management and utilization of natural resources between local indigenous Papuans and indigenous Papuan migrants in the Cyclops Mount Nature Reserve (CMNR). The study explored a wide range of information related to this issue qualitatively by using a mini-ethnography method. The study conducted in-depth interviews with informants from local and migrant communities and participant and non-participant observations. The study shows that the local indigenous Papuan utilized the area on a relatively sustainable basis. However, they were not able to prevent the use of natural resources in the CMNR by the indigenous Papuan migrants, resulting in environmental damage. To avoid further environmental damage to the CMNR, this study recommends the need for collaborative management of the CMNR area by involving both local indigenous Papuans and indigenous Papuan migrants with support from the government.

Abstract

Indonesia, known for its high biodiversity, is threatened due to alien plants that invade local plant species in forest areas. West Bali National Park is overgrown with invasive exotic plants, such as Lantana camara L., known locally as the kembang telek. The research aims to predict the distribution of L. camara using species distribution models (SDMs) and analysis variable contribution in the model featured in the biodiversity climate change virtual laboratory (BCCVL) application. L. camara distribution prediction model in Bali used the Bioclim data input by identifying areas of low, medium, and high habitat suitability. Central mountainous regions, including parts of Buleleng, Jembrana, Bangli, Karangasem, and Tabanan, show the highest suitability. Response curves demonstrated the correlation between climate variables and occurrence probability, highlighting the specific condition of rainfall and temperature ranges favoring Lantana's growth. The model showed a reliable AUC value of 0.89, indicating realibility. Potential improvements through additional environmental parameters were suggested. While L. camara has some potential benefits as a medicinal plant in Balinese culture, its invasive nature poses significant threats to native ecosystems. The predictive map offers valuable insights for authorities to implement initiative-taking strategies for preventing and controlling Lantanas spread in vulnerable areas of Bali.
