Abstract
The optimization of land use under teak (Tectona grandis) stands in post taungya system canbe enhanced by planting understory crops in a kind of three-strata agroforestry systems.Despite the potential, there is limited information on growth, morphophysiological adaptability,production, and phenotypic plasticity of the crops. this study aims to assess growth,morphophysiological adaptation, biomass production, and phenotypic plasticity of Calliandracalothyrsus
Abstract
The Seed Production Area (SPA) of sandalwood (Santalum album L.) in East Nusa Tenggara is Indonesia’s sole designated site for sandalwood seed production. It was established 32 years ago using trees from six provenances on Timor Island. The SPA supports regional economies and ecological protection by producing high-quality seeds for commercially valuable trees and species conservation. Despite annual seed collection, information on reproductive status,

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,
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

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
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

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
