Abstract:
Swietenia mahagoni is one of the commercial timbers in Indonesia. Mahogany heartwood is an important characteristic as it relates to the natural durability and aesthetics of the wood. Lipophilic extractives are known to be involved in the heartwood formation process. Therefore, this study aims to determine the lipophilic compounds associated with heartwood formation. The n-hexane extract from sapwood and heartwood samples (1 to 5 years) was analyzed by gas chromatography-mass

Mount Merapi National Park (TNGM) is one of the active volcanos in Indonesia. It has past volcano eruption history since 1911 up to date. Specifically, Plawangan Hill, a part of the TNGM, has periodically experiencedvolcanic eruptions.This study aimedto examine the quantities of nutrients in the soil and the vegetation growthin affected areasandto estimate when it would be feasible to start planting on Plawangan Hill shortly after a volcanic eruption.A field
Abstract
Intensive silviculture plays a crucial role in selecting superior clones with high productivity. The use of superior clones needs to be accompanied by appropriate environmental conditions. The arrangement of growing space is one way for teak clones to grow optimally and produce quality wood products. It can choose initial spacing in the early growth phase and thinning intensity in the later growth phase. This study aims to assess and determine the growth of
Abstract
Reclaiming tropical coal mines is a formidable task. The symbiosis between AMF and plants like Nauclea orientalis is crucial for thriving in tough environments. This study aimed to assess the potential of native AMF and N. orientalis in overburden pit soil for post-mining reclamation. Fifteen AMFs isolated from post-coal mining were screened for nutrient uptake, plant growth, and colonization using Sorghum bicolor as hostplant. The top three AMFs were rDNA
Abstract
The implementation of degraded land rehabilitation programs and community-based forest management certification is widely recognised to enhance the status of wono land cover and aid in climate change mitigation. The expansion of the restoration efforts can be monitored using satellite images to track the progress of operations by observing changes in land cover area. Community forest certification also can enhance the success of land restoration endeavours.

Abstract
Storage of Melaleuca cajuputi leaves and twigs affectsthe quality and yield of eucalyptus oil produced. The availability of raw materials from eucalyptus plantation forests is abundant, but the production capacity of eucalyptus biomass cooking kettles at PMKP Jatimunggul is insufficient, causing a decrease in yield because raw materials are stored for days and the transportation time from the BKPH supplier to PMKP Jatimunggul takes one day. Meanwhile, raw materials
Abstract
The establishment of fast-growing teak plantations in Indonesia provides opportunities for shorter harvesting periods. However, it also poses challenges on wood utilization due to juvenility and growth stress-related defects. This study investigated growth stress levels and some wood properties of 10-year-old fast-growing teak grown in Gunungkidul Regency, Yogyakarta. The strain gauge method was used to measure longitudinal surface released-strains (LRS), tangential
