Abstract

Aquilaria malaccensis is a member of Thymelaceae family which is one of the main trees producing agarwood compounds in Indonesia and has high economic value. A. malaccensis has Appendix II conservation status due to high exploitation in the nature.  One of the several efforts to maintain agarwood production while also maintaining agarwood population is efficient induction by manipulation of the pathway for agarwood formation and using individuals with higher production of agarwood compounds. Selection of superior individuals can be done using molecular markers that are linked to certain genes, including microsatellites or simple sequence repeats (SSR). This study aimed to identify SSRs in the agarwood transcriptome and characterized SSR sites that are linked to genes involved in the synthesis of agarwood compounds. The transcriptome data used was extracted from the NCBI database with accession number GHJS00000000.1. SSR mining was carried out using Krait v.1.4.0 software, then BLASTed with the protein database to analyze the linkage with the related genes. Perfect SSRs were found in 0.37% of the total sequences, and compound SSRs were 10.89%. The abundance of imperfect SSR (107,043) was greater than perfect SSR (31,262), indicating that SSR in the transcriptome had a low mutation rate and the SSR site was more conserved in A. malaccensis. The SSRs that linked to genes related to agarwood synthesis including HMGR, PAL, Mevalonate Kinase, MAPK, Delta-guaiene synthase, Farnesyl pyrophosphate synthase, and Phenylalanine ammonia-lyase. The discovery of SSRs linked to these genes can be used to create molecular markers that can be applied in agarwood producing trees selection.

Abstract

Nature Tourism Park play an important role as conservation areas that support biodiversity conservation while providing nature-based education and recreation spaces for the community. The purpose of this study is to determine changes in forest cover conditions and develop a spatial model of deforestation based on influencing factors in the Bangko-Bangko Nature Park. This study was conducted from February to May 2025 in the Bangko-Bangko Nature Park in Lombok Island. The data used included Sentinel 2A imagery 2020 and 2025, elevation, road networks, river networks, administrative boundaries, and population data. Land cover classification was performed using visual techniques (on-screen digitization). The spatial model of deforestation was constructed using the logistic regression method. The results of the study show that forest cover in the Bangko-Bangko Nature Park has decreased from 1.397 Ha in 2020 to 818 Ha in 2025, or deforestation of 579 Ha, or 115,8 Ha per year. The spatial model of deforestation at the study site follow logit equation: logit deforestation = -0,7759 – 0,002746*elevation – 0,000157*distance from road + 0,000406*distance from settlement – 0.000967*population density – 0,001258*distance from river + 0,019391*slope.

Abstract

Aboveground biomass plays a pivotal role in estimating tropical forest carbon stocks, particularly in Southeast Asia, a region rich in biodiversity but threatened by deforestation and land-use change. This systematic review analyzes 71 peer-reviewed studies published between 1995 and 2025, selected from an initial pool of 8,509 articles. The review aims to evaluate methodological developments and performance across three major approaches: field-based and allometric models, remote sensing including Unmanned Aerial Vehicle (UAV) platforms, and Machine Learning (ML) with data fusion, within key tropical forest countries: Indonesia, Malaysia, and Vietnam. These countries were selected due to their high forest cover, rapid land-use change, and central roles in the implementation of Reducing Emissions from Deforestation and Forest Degradation (REDD+). Field-based models, particularly those calibrated locally, consistently produced high accuracy, with R² values generally ranging from 0.80 to 0.96. Remote sensing techniques, particularly the integration of airborne LiDAR and optical–SAR, demonstrated strong predictive performance (R² > 0.85) and relatively low Root Mean Square Error (RMSE), typically below 30 Mg/ha. ML approaches such as Random Forest, Support Vector Machines, and LightGBM also achieved competitive results, with R² typically between 0.75 and 0.85 and RMSE below 40 Mg/ha when trained on high-quality input data. Mangrove and dipterocarp forests emerged as the most frequently studied ecosystems. While methodological innovations are evident, notable gaps remain in model harmonization and representation of ecosystem diversity. The review recommends integrating species-specific allometric models with remote sensing and machine learning pipelines, supported by open-access datasets, to enhance national forest monitoring systems and REDD+ readiness across Southeast Asia.

Abstract

Forest and land fires are recurrent in Indonesian tropical mountain savannas and threaten biodiversity, carbon stocks, and local livelihoods, yet spatially explicit burned-area information is still limited. This study aimed to evaluate the performance of the Burn Area Index (BAI) from Landsat 8 OLI–TIRS imagery for mapping the 2024 fire in Bukit Anak Dara, East Lombok. Burned and unburned pixels were classified by applying a two-class Otsu threshold to the ΔBAI histogram for the full scene extent. The resulting burned-area map was validated against high-resolution polygons obtained from visual interpretation of Sentinel-2A imagery and against fire hotspots from the SiPongi+ system. Compared with Sentinel-2A polygons, the ΔBAI–Otsu method produced a burned-area estimate of 275.49 ha versus 318.87 ha from the reference and achieved an overall accuracy of 0.97, precision of 0.94, recall of 0.81, and an F1-score of 0.87. Validation against hotspot data yielded lower performance (overall accuracy 0.87, precision 0.40, recall 0.41, F1-score 0.41), reflecting conceptual and spatial-scale differences between point-based active-fire detections and patch-based burned-area mapping. Burned pixels were concentrated on west–northwest facing slopes dominated by dry savanna, highlighting the role of topography and fuel characteristics in fire spread. Overall, the results therefore indicate that the ΔBAI–Otsu approach is a rapid, transparent, and reproducible tool for post-fire burned-area mapping in tropical mountain ecosystems and has strong potential for routine operational monitoring.

Abstract

This research examines the ecological dominance and ethnobotanical potential of medicinal plants found along the Mayung Polak Waterfall Trail, located in the Timbanuh Resort of Mount Rinjani National Park (MRNP). By combining vegetation analysis with descriptive ethnobotany, the study investigates how plant community structure correlates with the medicinal potential of the species in the area. Vegetation data were obtained by placing 2 × 2 m plots (4 m²) at 200-meter intervals along the trail, alternating between the left and right sides. The vegetation analysis calculated density, frequency, and the Important Value Index (IVI) to evaluate the dominance of species. Ethnobotanical information was collected through direct field observations and a review of existing ethnobotanical and ethnopharmacological literature, without conducting formal interviews. The results show that the medicinal plant community is dominated by species with high IVI values, such as Chloranthus officinalis, Piper nigrum, and Elephantopus mollis. These species act as key elements in the understory and have been widely recognized for their medicinal uses in traditional practices. Their ecological dominance indicates strong adaptability to the moderate disturbances of the trail environment. The combined use of IVI analysis and ethnobotanical data underscores that species with higher ecological dominance are more likely to have significant medicinal uses, offering valuable insights for the sustainable management and conservation of medicinal plants along MRNP's tourist trails.
