Abstract
This study aimed to identify the species composition and diversity of tree habitus in Mount Merbabu. A purposive, systematic sample using a survey technique based on elevation gradient, i.e., A (1,500-2,000 m asl), B (2,000-2,500 m asl), and C (>2,500 m asl), was employed in this study. Fifty-nine sample plots, each measuring 20 m × 20 m, were established along five hiking tracks. The results showed that the tree species composition at elevation gradients read more

Abstract
Mangrove forests are a transitional ecosystem located between land and sea. Habitat factors greatly influence the growth of mangrove plants. Habitat suitability is reflected in the suitability of the species that can grow in the habitat. Increased growth will ultimately increase water productivity, which can be seen from the presence of various types of biota and environmental improvements. The local community planted mangrove species (Sonneratia sp.) along read more

Abstract
In this systematic review, the application of density functional theory (DFT) in adhesive research is examined, with a focus on optimizing adhesives at the atomic level, understanding molecular interactions, and exploring their applications in wood products. This study evaluates researches employing DFT across various adhesive systems, including polymers, proteins, and bio-based materials. From 18 published articles that implemented DFT on adhesive analysis, read more

Abstract
Indonesia has extensively reforested mangroves to stabilize coastal ecosystems and mitigate climate change. Reforestation’s long-term effects on recovering mangroves are not extensively established because most projects are only observed for two years. It raises the question of whether mangrove replanting aids biodiversity conservation and ecological recovery. This study will characterize Flores Island mangrove ecosystems after ten years of regeneration. read more

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 read more

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 read more

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 read more

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 read more
