Abstract
LAI measurement using a direct method is time-consuming, while other instruments like Ceptometer, Hemispherical Photography, and LI-COR require high investment. This study aims to develop allometric equations for estimating the LAI of community forest tree species. Destructive sampling was conducted on 45 trees from three different species, i.e., Tectona grandis, Swietenia macrophylla, and Falcataria moluccana . The allometric equations were developed using

Abstract
Land limitation dramatically affects people with land-based livelihoods, such as farmers, and is often an obstacle to earning sufficient income for their family’s needs. Privately owned forests (POFs) are a land-based farming activity with a long history in Indonesian society. This study aimed to determine the socio-economic conditions, inequality, poverty, and livelihood dynamics of POF farmers. The research was conducted in three villages in Ciamis Regency,
Abstract
Increasing food demand and climate change-induced natural disasters pose significant challenges to food security. This study examines how forest conservation can mitigate disaster risks to agricultural land in Northern Thailand’s watershed. The Soil and Water Assessment Tool (SWAT) and Hydrologic Engineering Center’s-River Analysis System (HEC-RAS) models were used to assess flood impacts, while the standardized precipitation and evapotranspiration index
Abstract
Even before Indonesia’s independence, its leaders had drafted plans to relocate the capital city. Proponents gave various reasons at different times, but with Jakarta’s stifling traffic and perennial flooding, the government is now translating visions of relocation into action. Construction of the new capital, Nusantara, is already underway in East Kalimantan province. Nusantara is an ambitious and symbolic nation-building project that positions Indonesia
Abstract
Microsatellite DNA markers are known to have a high level of genetic diversity and can be used for various purposes. These include population genetic analysis, gene flow assessment, pollen distribution, parent analysis, and accurate distinction between types and varieties. Despite the potential application of microsatellite markers, their development process often requires high costs, energy, and time. To overcome the limitations, several studies have proposed
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
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
