Abstract

Abstract Community Service entitled "Empowering Forest Communities through the Application of the Sonokeling Tree Barcoding System as an Effort for Forestry Social Disaster Management in Wan Abdul Rahman Forest Park, Lampung Province" is motivated by the condition of the Tahura Wan Abdul Rahman area which is vulnerable to illegal logging, especially the Sonokeling (Dalbergia latifolia). Illegal logging is one of the social disasters of forestry and threatens the sustainability of forests and the various resources in them. This is also faced with the limited personnel of related institutions in dealing with social disasters. Therefore, the PkM team consisting of ITERA lecturers from the Forestry Engineering Study Program assisted in gathering information regarding the potential of sonokeling stands in Tahura WAR and developing a barcoding system (QR Code) that would facilitate monitoring and securing rosewood stands from the threat of illegal logging. The barcoding system application is also expected to be able to support the Tahura WAR foster tree program which will be initiated later to increase community empowerment in maintaining forest sustainability. Keywords: foster tree, WAR Forest Park, QR Code

Abstract

Mangrove ecosystems are important coastal ecosystems that provide a variety of functions. Mangrove ecosystems provide a variety of environmental services including absorbing carbon and contributing to climate change mitigation, protecting coastal areas from storms, tsunamis, and erosion. In addition to providing a variety of environmental services, these ecosystems are also habitats for a variety of living organisms, both aquatic and terrestrial, resident and migrant, also nationally and internationally protected species. The benefits provided by mangrove are contrast to the rate of degradation, which has the potential for loss of wildlife habitat and a decrease in biodiversity value, especially mammals. This study was conducted to analyse the value of biodiversity, especially mammals in the Mangrove Ecotourism Area, Pesawaran Regency. This study uses the method of line transects, mist nets, and sound identification. The results of the study recorded 6 species of mammals with a species diversity value (H') of 1.46, richness of 1.60, evenness of 0.72, and species dominance of 0.30. Mammal species diversity inside the ecotourism area is higher than outside the area. Protected mammals are not found in the area.

Abstract

This research was based on the condition of the Ulubelu District area, which experienced a decrease in environmental quality and coffee yield productivity. Coffee plantations in Ulubelu District, Tanggamus have experienced a reduction in productivity over the last three years. This reduction in quality is due to the age of the less productive coffee plants (30-40 years) and the lack of shade trees. This study aims to determine the effect of shade trees on coffee productivity and land conditions in coffee agroforestry systems on farmers' land. This research was carried out to increase the productivity of coffee plantations economically and ecologically. The initial stage of this research is collecting secondary data on the application of agroforestry by coffee farmers in the Ulubelu area. The results showed that Ulubelu farmers had implemented agroforestry principles, but they are not optimal in terms of the percentage of shade trees and types of trees planted. Therefore, the recommendation is to plant shade trees of Indigofera sp. with the characteristics of deep roots and the leaves are used to feed cattle. Key words:agroforestry, shading trees, productivity, coffee plants, Ulubelu

Abstract

Biopellets from gamal wood (Gliricidia sepium) as a biomass energy resource could be an alternative to replace fossil fuels due to having met standards based on moisture content, ash content, fixed carbon, calorific value, and density. Unfortunately, they still had high levels of volatile matter. Robusta coffee husk was a material with high nitrogen content, which is suspected of being able to bind aromatic substances in volatile organic compounds. This study aims to evaluate the quality of biopellets and determine the optimum composition of the biopellets from gamal wood and coffee husk. The blended composition of gamal wood and coffee husk biopellets studied were 100:0, 75:25, 50:50, 25:75, and 0:100. The biopellets were manufactured using the material size of 40-60 mesh with a pressure of 173.51 MPa. The best biopellet was produced in the composition of 75% gamal wood and 25% coffee husk, with a density of 0.85 g/cm3, moisture content of 8.03%, ash content of 3.92%, volatile substances of 78.01%, fixed carbon of 18.07%, and calorific value of 4,176 cal/g. The biopellet quality met the standards of SNI 8021:2014 and EN 14061-2, except for ash content. Adding coffee husk reduced gamal wood biopellet’s volatile matter, increasing the fixed carbon and density of gamal wood biopellets.

Abstract

Geothermal Power Plants are one of the geothermal energies that can be used as a source of electricity. One of the geothermal powers in Lampung is the Ulubelu PLTP located in Tanggamus Regency. As an energy-producing agency, Ulubelu PLTP also contributes to preserving flora and fauna in their work area. This is shown through the planting of several types of wood plants to improve the flora in their work area. This study aims to record the types of plants that exist, the abundance of their types, climatic and edaphic factors, as well as recommendations for types that can be used for the enrichment of flora types in the Ulubelu PLTP work area. The vegetation analysis method used to collect flora data is a census method divided into 5 observation lines. The dominant and codominant types found at the tree level are Acacia mangium and Erythrina variegata, at the pole level Leucaena leucocephala and Toona sureni, at the pile level Gliricidia sepium and Syzygium myrtifolium, and at the lower plant level are Imperata cylindrica and Mikania micrantha. In addition to commercial types, some types have the potential to be invasive in the Ulubelu PLTP. The study also recommends that plant species be restored to increase species diversity and vegetation density. The types recommended for restoration based on vegetation analysis data are those that have aesthetic value, those that produce fruit or flowers that can present animals, and the protected types or types that can be used in addition to their wood.

Abstract

Fruit bats (family Pteropodidae) pollinate around 300 species of tropical plants of high economic value over a wide range of areas. This large role does not match the status of their population, which continues to decline due to habitat loss, particularly in urban areas. The Sumatra Institute of Technology (ITERA) campus, which is currently under development, may result in habitat changes that may affect bats. These concerns have led to the need for research into bat diversity on the ITERA campus. The result could be utilised to monitor and develop the environmental management of the campus. The research was conducted from May to September 2023 in five different habitat types. Data were collected using 3 mistnets and 3 night repetition each habitat. The data were analysed using indices of diversity, evenness and species richness. The study recorded 143 individuals of 7 species. The highest number of species and diversity was observed in the sengon and rubber habitat (6 species). The lowest number of species and diversity was found in the botanical garden (2 species).

Abstract

Mangrove forests are important for storing carbon dioxide (CO2) and reducing the effects of climate change. Indonesia possesses 20% of the global mangrove cover, which substantially impacts global climate mitigation efforts. However, understanding of the diversity of plant species in mangrove forests remains limited, as evidenced by the high rate of conversion of mangrove areas into aquaculture ponds, resulting in mangrove degradation. Our research in Pantai Mekar Village was conducted to augment information on mangrove plant species diversity in Indonesia, specifically in Bekasi Regency. Mangrove vegetation data were collected in Pantai Mekar Village, Muara Gembong, Bekasi from 8 to 12 July 2019. Data were collected using 2x2 m (seedlings and understory), 5x5 m (saplings), and 10x10 m (trees) plots. Importance value index (INP), Shannon-Wiener species diversity, evenness, richness, and carbon stock estimation were utilized to analyze the data. The study documented 21 species from 15 families. Species from the Acanthaceae family were predominant in the study site. Avicennia alba was the species with the largest biomass and carbon content. The estimated biomass contained in Mekar Beach is 380.42 tonnes/Ha with carbon sequestration of 190.21/Ha.

Abstract

Estimating forest biomass is essential for sustainable forest management and carbon monitoring. This study aimed to develop an aboveground biomass (AGB) estimation model by integrating multispectral Landsat-8 OLI imagery and field measurements in a 95.76 ha rehabilitation area near Rindam II Sriwijaya, Muara Enim, South Sumatra. Field data were collected using the National Forest Inventory Protocol, recording tree diameter and height to calculate AGB through species-specific allometric equations. Several vegetation indices (NDVI, EVI, SAVI, MSAVI, RVI, TVI, NDWI) were derived and analyzed on the Google Earth Engine (GEE) platform to identify the most responsive spectral indicator for biomass estimation.The analysis showed that AGB and carbon stocks varied across the rehabilitation site, reflecting differences in stand structure and vegetation moisture. Among all tested indices, NDWI demonstrated the highest correlation with AGB, indicating its effectiveness in capturing canopy water content and biomass variation under humid, mixed-vegetation conditions. These results emphasize the potential of GEE-based vegetation indices as a cost-efficient and replicable approach for monitoring biomass in tropical rehabilitation forests. NDWI proved to be the most suitable index for modeling forest biomass, offering a practical reference for applying similar remote sensing methods in other tropical regions to support large-scale forest carbon assessments
