Abstract
Shoot waste refers to the parts of trees that are not yet optimally utilized. In this study, we aimed to utilize shoot waste of fast-growing teak (FGT) extracted from the community forest in Wonosari, Gunungkidul, Yogyakarta Special Region, Indonesia by converting it into charcoal, followed by further conversion into activated carbon. This study was conducted with two treatment factors of the activation process, including thermal treatment (750°C, 850°C,
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
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

Abstract
Wind damage in Eucalyptus plantations are one of the main factors affecting fibre productivity losses in Sumatra, Indonesia. High levels of damage start between 1.5 and 3.5 years old, with total wind damage of between 7 % and 15 % by area in Eucalyptus plantations. The characteristics of the plantation stands are the most critical factors influencing the level of damage. In this study, the ForestGALES wind damage risk model was parameterised for Eucalyptus
Abstract
The micro-zonation of vegetation was developed by using the criteria and sub-criteria derived from other objectives, as documented in the literature of previous studies. This study employed the K-means clustering algorithm to discern variations in the criterion. The Analytical Hierarchy Process (AHP) analytical technique was utilized to estimate the weight and score of criteria that were vital for producing the micro-zonation of vegetation. Hence, the data
Abstract
Monitoring and visiting farmers affected by fish mortality is imperative. It offers insights into fish disease mapping and the trend of antibiotic resistance, serving as a fundamental for future strategies for preventing and treating fish diseases. The data collection was carried out by visiting farmers who suffered from fish mortality in 2022 in East Java, South Kalimantan, and Bali provinces. A total of 128 samples of infected fish were collected and analyzed
Introduction
This study estimates community forest tree species’ energy using allometric models. Accurate tree-level energy stock estimation is needed to evaluate community forest tree species for renewable energy development. Three commercial species in community forests utilized as temporary energy sources, Falcataria moluccana, Swietenia macrophylla, and Tectona grandis were sampled by cutting 45 trees. Those tree types were investigated as co-firing materials
Abstract
Abaca, one of the potential fiber crops with high-quality fiber and promising economic value, is mainly established under the agroforestry system, for it is considered a non-primary crop. The study aims to observe the metabolic and biochemical performance as well as the fiber quality of abaca under the agroforestry system. The experimental design used in this study was nested with two types of agroforestry systems, i.e., intermediate phase (Fase Tengah, FT)
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
