Abstract
The rates of appearance of new mutations play a central role in evolution. However, mutational processes in natural environments and their relationship with growth rates are largely unknown, particular in tropical ecosystems with high biodiversity. Here, we examined the somatic mutation landscapes of two tropical trees, Shorea laevis (slow-growing) and S. leprosula (fast-growing), in central Borneo, Indonesia. Using newly constructed genomes, we identified read more

Abstract
The devastating eruption of Mount Merapi, Indonesia, in 2010 resulted in the alteration of vegetation composition and structure across the exposed area, and it has been invaded by Acacia decurrens Willd. ever since. Nevertheless, A. decurrens provides a suitable agroecosystem for silvopasture, which has been considered the essential source of income for the society around Merapi. This research aims to observe the diversity and potential forage species under read more

Abstract
To evaluate the inheritance of natural durability of Acacia mangium Willd., wood-color parameters (Y [lightness], x [red to green], and y [yellow to blue]), mass loss by a white-rot fungus (Trametes versicolor) and brown-rot fungus (Fomitopsis palustris), and three different extracts (methanol extract, total phenol, and total flavanol content) were measured using the inner and outer heartwood of 10-year-old trees from 20 half-sib families in the third-generation read more

Abstract
Despite its considerable potential, oil palm trunk (OPT) remains underutilized, largely owing to the cyclical replanting process that occurs every 25–30 years. This study aimed to address this issue by developing an ecofriendly oriented strand board (OSB) using vascular bundles (VBs) from oil palm, both in binderless form and with the incorporation of natural adhesives made from sucrose and ammonium dihydrogen phosphate (ADP). The VB was extracted read more

Abstract
Manfaat keberadaan hutan belum sepenuhnya dapat dirasakan oleh masyarakat karena deforestasi. Perhutanan sosial merupakan salah satu kebijakan dalam mengatasi problem tersebut. Dalam pelaksanan program perhutanan sosial, peran gender menjadi penting. Hal ini juga sejalan dengan Tujuan SDGs ke 5 menyebutkan adanya Kesetaraan Gender. Penelitian ini bertujuan untuk mengidentifikasi peran gender dalam pengelolaan kawasan hutan. Penelitian ini dilakukan di Kelompok read more

Abstract
Two first-generation progeny trials of Ficus variegata Blume were planted in Yogyakarta, Indonesia, consisting of 17 families from the provenances of West Nusa Tenggara (WNT) and 19 families from the provenances of Cilacap-Pangandaran (C-P), respectively. The trials were evaluated after 10 years for growth characteristics [diameter (D), tree height (H) and stem volume (V)] and wood properties [stress-wave velocity (SWV) and Pilodyn penetration (P)]. Genetic read more

Abstract
Teak tree breeding programs have been conducted over the last several decades in various locations throughout Indonesia. These programs have produced superior teak clones with growth increments > 3 cm diameter at breast height. The wood quality of this clonal teak must be evaluated to determine the final use of these trees and the success rate of the teak breeding programs. In this study we investigated the physical condition (reflected in wood color and read more

Abstract
Gunung Merapi National Park (GMNP) is an inseparable conservation area from the surrounding community, as the buffer village community has used its existing forest resources. Therefore, this research aimed to identify the forest resources used by the buffer village community and assess the economic benefit value generated by GMNP. The economic benefits evaluation adopted the direct use value approach and market prices. The results showed that the community read more

Abstract
The most dominant community activities are sand farming and tourism, while government intervention is in the form of infrastructure development, establishing conservation areas, protection, and tourism. The coastal areas of Bantul and Kulon Progo Regencies in DI Yogyakarta are naturally influenced by the supply of sand sedimentation from Mount Merapi, wind, and beach wave energy. However, this area has now become an area for agriculture, tourism, and other read more
