Abstract
Pro-environmental behavior is increasingly demonstrated by the younger generation across the globe. In Gunungkidul, a rural region of Indonesia, the young generation initiated the resan community that emerged in response to the Cempaka hurricane of 2017, focusing on revitalizing local springs as reservoirs to mitigate prolonged dry seasons caused by climate change. This study explores the formation, worldviews, and perceptions surrounding the resan community’s

Abstract
Bamboo waste from the handicraft and furniture industry is an excellent source of lignocellulose with significant potential for use as raw material in particleboard production. The bamboo particleboard, when paired with a natural adhesive such as maltodextrin-based adhesive, potentially provides an eco-friendly wastemanagement solution, aligning with Sustainable Development Goals (SDGs) 12 and 13. The optimal manufacturing conditions for maltodextrin/ammonium
Abstract
Several non-edible plants, including kepuh (Sterculia foetida), are used as feedstock for biodiesel production in Indonesia. This study aimed to evaluate site-specific variations in biodiesel yield, characteristics, and chemical composition from seeds of S. foetida from 25 locations on Java Island and select superior seed sources for renewable energy development based on the quality of the produced biodiesel. The biodiesel yields ranged from 23.6% to 26%. The
Abstract
This study evaluated the greenhouse gas (GHG) emissions reduction potential of utilizing empty fruit bunch (EFB) pellets from Indonesia as a power generation fuel in Japan. EFB is commonly processed through mulching or combustion; thus, these methods were used as the reference scenarios to compare emissions with EFB pellet utilization. Additionally, we assessed whether EFB pellets could outperform coal-fired and liquid natural gas (LNG) combined cycle power
Abstract
Bamboo, one of the non-timber forest products, is promising in climate change mitigation strategy due to its ability to remove COfrom the atmosphere through photosynthesis. However, the allometric model to estimate the biomass 2and carbon of bamboo is still limited. The research aimed to develop the allometric model using the diameter as the predictor. The materials for destructive sampling were 30 culms of yellow ampel bamboo (Bambusa vulgaris var. striata).
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:
This research aimed to analyze variation of the anatomical characteristics (cell dimension and proportion) in axial and radial direction of Acacia aulacocarpaplanted in Indonesia. Three trees of 27-year-old A. aulacocarpaplanted in Gunung Kidul Yogyakarta were used. This research covered a completely randomized design with two factors, the axial direction (base, middle, and top of the stem) and the radial direction (near pith, middle, andnear bark) in triplicate.
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
