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)].

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.

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

Abstract
Soil and water conservation is one of the keys to preserving natural resources. Livestock development can optimize the use of grass for soil and water conservation. However, livestock manure waste is a problem for the environment and health. This study aimed to explore the role of biogas technology in supporting the strengthening of soil and water conservation in the Merawu Subwatershed. Through a community empowerment approach, this research included educational read more

Meningkatnya akumulasi dan distribusi patogen, dipadukan dengan kondisi kelembapan dan suhu yang meningkat akibat perubahan iklim, dikhawatirkan akan mempercepat laju infeksi pada tanaman hutan. Hal ini dapat berakibat fatal bagi ekosistem hutan secara keseluruhan.

Meskipun beberapa patogen populasinya menurun karena kondisi inang yang justru menjadi kuat oleh pemanasan global.  Peran patogen sebagai agen pengganggu tanaman hutan akan meningkat dan memberikan dampak buruk pada ekosistem hutan. read more
