Abstract
Indigofera tinctoria L. is known to produce economically valuable indigo dye. Recently, I. tinctoria has also been considered a potential species for establishing energy plantations because this species can rapidly produce large quantities of biomass. However, knowledge about its fuelwood properties is still limited. To optimize utilization of this biomass material as a source of energy, the fuelwood properties of this species were evaluated. In addition, the

Abstract
Gum rosin, a distillation product of pine sap with turpentine as a co-product, is a significant non-timber forest product (NTFP) in Indonesia. This study evaluated the social sustainability of gum rosin production across four factories in Central Java during a three-year period of 2020–2022 through a Social Life Cycle Assessment (SLCA). The study focused on social performance and identifying social hotspots using the Subcategory Assessment Method (SAM) based
Abstract
To switch the origins of wood resources from natural to planted forests, evaluation of wood from planted trees is essential. The objective of this study is to provide the relevant wood properties promoting the utilization of wood from planted trees in the tropics. Growth characteristics (stem diameter at 1.3 m above the ground and tree height) and stress-wave velocity of stems were measured for two six-year-old red meranti species, Rubroshorea leprosula and
Abstract
Pinus merkusii shows great potential as a resin-producing wood in Indonesia, with the global demand for pine resin reaching 1 million tons annually. This study investigated the effect of ethephon on the anatomical properties of P. merkusii, particularly the resin duct that affects resin productivity, to increase the efficiency of pine resin tapping. Ethephon was mixed with Vaseline to create concentrations of 0%, 2%, 4%, and 8% and then applied to the seedlings
Abstract
Understanding drought propagation is essential for effective water resource management. This study employs an innovative approach to examine the transition from meteorological drought (MD) to hydrological drought (HD) in the Upper Nan Watershed (UNW), Thailand, using the standardized precipitation evapotranspiration index (SPEI) and standardized streamflow index (SSI). Cross-wavelet transform (XWT) and Pearson’s correlation analyses reveal a significant positive
Abstract
This study examines four regression models to estimate tree-level above-ground carbon stock (AGC) in the clonal teak plantations of Wanagama Forest, Indonesia using a data fusion of UAV-LiDAR and RGB aerial imagery. Data collected in the field were diameter at breast height and tree height. Vegetation indices were derived from the visible bands of a georeferenced orthomosaic captured by DJI Mavic 2 Pro. The LiDAR data was obtained using GeoSun GS-100M device
Abstract
We explore the impact of teaching methods and learning styles on student engagement in a conservation education program focused on primate conservation in Indonesia. Engaging students is essential for fostering environmental literacy and encouraging pro-environmental behaviours. We assessed the effectiveness of active versus didactic teaching methods and visual, auditory, and kinaesthetic learning styles in enhancing engagement. Using a formative assessment
Abstract
The tropical rainforest of Kalimantan, Indonesia, is dominated by a mixed dipterocarp forest. Rubroshorea johorensis is a commercial species of the Dipterocarpaceae family but is listed as vulnerable. So far, the management of natural forests through selective logging may have a negative impact on genetic diversity. Therefore, this study was conducted to determine the genetic diversity of R. johorensis in different forest types representing the management and
Abstract
Tribal leaders in Papua had been positioned as both cultural symbols and real decision-making leaders, but they have lost their power over natural resource management and forests. Using the case of nutmeg management by the tribal Baham-Matta community, we present changes in the power constellations within the local social structures, in which the Kings (Patuans), the highest tribal leaders, have increasingly been unable to rule their people. In this research,
