Abstract
Mangrove forests play an important role in climate change mitigation and have attracted significant attention from scholars, governments, businesses, and non-governmental organizations. Therefore, this study aims to (1) describe land cover changes caused by rehabilitation activities and (2) investigate the dominant factors affecting mangrove improvement through rehabilitation activities. Land cover changes were monitored using Landsat 5 TM, Landsat 7 ETM+,
Abstract
Global warming, a critical component of climate change, refers to an increase in average temperatures across the atmosphere, oceans, and land. Global warming is primarily caused by the accumulation of greenhouse gases. As an archipelagic nation, Indonesia plays a critical role in mitigating climate change, as outlined in its Nationally Determined Contribution. The Indonesian government announced the B40 policy, requiring a 40% palm oil blend with 60% diesel,
Abstract
Kawui tree or Vernonia arborea is a lesser-known woody species, originated from Kalimantan Island, Indonesia. It is one of the potential materials for pulp and paper, which produces high bark residue. Furthermore, its rich background as folklore medicines suggested the medicinal properties of V. arborea. This study aims to explore the chemical extractives of V. arborea bark and their bioactivities. The bark samples were successfully extracted using n-hexane,

Harto S, Musyafa, Sumardi, Hardiwinoto S, Dewi RA, Puradyatmika P, Sarwom R. 2025. Collembola diversity across three successional stages in a reclaimed tropical mining tailing site, Central Papua, Indonesia. Biodiversitas 26:2210-2220.Reclamation of tailing-impacted land by PT Freeport Indonesia aims to mitigate soil degradation and restore the underground microfaunaecosystem. Collembolas are utilized as bioindicators to evaluate reclamation
Abstract
Strychnos lucida R.Br. is a medicinal plant believed to treat various diseases. The study aimed to identify the phytochemical compounds, total phenolic content (TPC), antioxidant, and antibacterial activity of the root, seed, stem, and leaf of S. lucida. Antioxidant activity was examined using the DPPH method in the methanol extract. The extract of four parts of S. lucida was tested against three bacteria (Bacillus subtilis Inacc-B334, Staphylococcus aureus
Abstract
Orangutan population sizes have been declining rapidly during the past decades. Proxies for the status of populations range from simple presence/absence data to estimations of absolute density. A variety of monitoring methods are available, including human observations, camera trapping, acoustic monitoring and aerial surveys. This qualitative review provides a comprehensive overview of population monitoring methods and associated metrics, discussing their strengths,
Abstract
Peatland ecosystems play a critical role in conservation of biodiversity and climate regulation, but face ongoing degradation from land-use change, mining, and infrastructure development. In response, peatland restoration has gained global attention. This bibliometric study analyzed 448 publications from the Web of Science (1996–2024) to identify global research trends, influential contributors, collaborative networks, technological developments, and implementation
Abstract
Walikukun (Schoutenia ovata Korth.) is a commercially significant wood species in Indonesia. Heartwood, in particular, is important due to the natural durability and aesthetics, while lipophilic extractives play a crucial role in the formation. Therefore, this study aimed to determine the levels of lipophilic compounds in different radial positions associated with the formation of Walikukun heartwood. The results showed that the mean of n-hexane, methanol,
Abstract
This study investigates the effects of deforestation and climate change on water flow regulation within the mixed-deciduous-forest-dominated Upper Nan Watershed in Northern Thailand. Using the SWAT model, hydrological changes were analyzed under 16 land-use scenarios and CMIP5 climate projections (RCP4.5 and RCP8.5) for both historic (1980–2020) and future (2021–2080) periods. Findings reveal that increasing rainfall variability under RCP8.5 amplifies hydrological
Abstract
The optimization of land use under teak (Tectona grandis) stands in post taungya system canbe enhanced by planting understory crops in a kind of three-strata agroforestry systems.Despite the potential, there is limited information on growth, morphophysiological adaptability,production, and phenotypic plasticity of the crops. this study aims to assess growth,morphophysiological adaptation, biomass production, and phenotypic plasticity of Calliandracalothyrsus
