Yogyakarta, August 26, 2025 — The IX International Forestry Summer Course (FSC) 2025, themed “The Forest Nexus: Innovation in Food, Energy, and Water Sustainability”, officially ended with a closing ceremony led by Ir. Dwiko Budi Permadi, S.Hut., M.Sc., Ph.D., IPU, Vice Dean for Academic and Student Affairs, Faculty of Forestry.
Held from August 11 to 26, 2025, this two-week program brought together 36 participants from 11 countries. The
Wanagama – A total of 61 students from the Faculty of Forestry, Universitas Nusa Bangsa (UNB), class of 2022 and 2023, have successfully completed the General Forestry Practice (PUK) at the Wanagama I Special Purpose Forest Area (KHDTK). The practice was held over a period of 10 days, from August 5 to 15, 2025, with the aim of providing students with hands-on experience in applying classroom knowledge directly in the field.

Abstract
The increased demand for lightweight wood products requires genetic improvements in the growth, wood properties, and stress tolerance of fast-growing timber species. Falcataria falcata (Leguminosae) is one of the fastest-growing trees worldwide and an important multipurpose plantation species. This species is distributed across various geological locations in Southeastern Asia and Melanesia; therefore, populations from different regions may show phenotypic
Abstract
Urbanisation alters ecological processes and reshapes biodiversity patterns, with significant implications for bird communities. This study examined avian community structure across an urban gradient in Daerah Istimewa Yogyakarta, Indonesia, by integrating field surveys with remotely sensed environmental variables. Bird species richness and composition were assessed at 300 observation points stratified by urbanisation class. Environmental predictors, including
Abstract
Acacia aulacocarpa A.Cunn. ex Benth is considered a potential source of fiber for the pulping and paper-making industries. This study aimed to evaluate the properties of Acacia aulacocarpa kraft pulp in relation to the presence of extractive. A separate assessment was conducted on the chemical composition and pulp properties of the sapwood and heartwood. Extractive removal was achieved with various organic solvents including n-hexane, ethanol, and hot water
Abstract
Teak (Tectona grandis) is a valuable tropical tree species that is widely planted in more than 65 countries, including extensive plantations on Java Island, Indonesia. Java plays a critical role in global teak production. However, few studies have assessed the genetic diversity and local adaptation of this species using genome-wide sequencing data across its natural distribution and Indonesian landraces. Analysis of genetic structure and local adaptation can
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.
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
