Abstract
To produce the next generation of Acacia mangium Willd. in Indonesia, radial variations of wood fiber and vessel element length, air-dry density, modulus of elasticity (MOE), modulus of rupture (MOR), and compressive strength parallel to the grain were investigated for 20 half-sib families of the third-generation trees. A radial variation modeling approach was applied to detect the differences in the radial variation of wood properties among families. In addition, read more

Abstract
Angiosperm trees develop tension wood on the upper side of leaning stems to reorient the direction of stems towards their normal positions in response to a gravitational stimulus. The development of gelatinous fibers with thick inner gelatinous layers (G-layers) might elevate tensile stress required for such reorientation in many angiosperm species. This study aims to investigate negative gravitropism and tension wood formation in response to a gravitational read more

Abstract
Accurate microtopography data are an important input for characterizing small-scale rill erosion and its progression following disturbances. UAV–LiDAR systems are increasingly accessible and have successfully been used to measure microtopography data for several applications. Yet, the use of UAV–LiDAR systems for rill erosion studies in post-landslide landscapes have not been well investigated. Therefore, the purpose of this study was to implement and evaluate read more

Abstract
Coastal areas are classified as highly vulnerable because they are always tied to changes in the global aquatic environment. The ecosystem dynamics are increasingly complicated and complex as a result of interactions with other systems on land. This phenomenon is very visible in the coastal areas of Bantul Regency and Kulon Progo Regency. We use Sentinel-2 satellite image interpretation in the period 2013-2022 as a historical record of land use change, and read more

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
