Abstract

Indonesia is a major cinnamon (Cinnamomum sp.) exporting country in the world. Previous research generally measured the information on competitiveness. To improve performance, export demand behavior should also be known. This study aimed to estimate Indonesia’s cinnamon export demand function. The panel data model was investigated using panel data exports to 11 country destinations from 2010 to 2020. The classical assumption test of heteroscedasticity and autocorrelation and the model specification test were conducted. The results show that the export demand function can be represented well by the fixed-effects model, which explains about 96% of its variance. The obtained income and price elasticities were 1.08 and -0.30, indicating normal goods with inelastic export demand. It implies that countries with high-income growth should be prioritized in export expansion, and raising an export price might be a good policy option. Research on global supply chains and price volatility is needed. In addition, this study results in formulating policies related to developing the cinnamon product industry and trade. Keywords: Cinnamomum sp., data regression, demand, export, function panel

Abstract

Dipterocarp species are the mainstay of forest products in the form of woodworking. Dryobalanops lanceolata is one of the dipterocarp species. The study aimed to analyze the effect of canopy cover on the growth and carbon storage of 6-year-old D. lanceolata. Data were collected by measuring diameter, height, canopy cover, soil samples, and carbon storage. The research method was carried out by regression between canopy cover and tree diameter and height growth, analyzing soil fertility and carbon content. The 6-year-old D. lanceolata has grown well with a canopy cover of less than 34% (canopy openness of more than 66%) and could grow on clay soil with acidic pH. D. lanceolata at the age of 6 years has been able to improve the nutrient content in the soil. Under 6-year-old D. lanceolata stands, it has provided significant changes to increase the availability of soil nutrients for C-organic, total N, and K-available content. Carbon storage in D. lanceolata has increased in 1 year by 41.91%. Keywords: biomass, canopy cover, carbon growth, Dryobalanops lanceolata

Abstract

Musang King Durian (MKD) is in high demand due to its unique taste and aroma; hence, some opportunistic farmers grow it on a large scale. The issue arises when some MKD is planted on encroached land in remote places, making it impossible for local authorities to locate them. This study proposes to examine the changes in land use land cover (LULC) within the Benom Permanent Forest Reserved area that were reported to have land invasion activities caused by illegal MKD plantations between 2019 and 2022 using Sentinel imagery. The objectives were to investigate the location of illicit MKD farming at Mount Benom based on the interpretation of LULC changes and Normalized Different Vegetation Index (NDVI) analysis. ArcGIS and eCognition Developer software were used for data processing and analysis to identify water bodies, bare land, green areas, forests, and potential illegal MKD plantings (PIDP) areas. Between the years 2019 and 2022, it was found that there has been a significant rise in water bodies (36%), green areas (34%), and forests (19%). However, the potential illegal MKD plantation area fell by 59%, while bare land declined by 35%. These downsizing changes might occur due to illegal MKD destroyed operations executed in 2019 by the forestry department in Raub, Pahang. Keywords: illegal farming, image classification, land use land cover, supervised classification

Abstract

A management unit-based land cover change analysis was examined in Kahayan Tengah Forest Management Unit (FMU) to understand past, present, and future land cover to assist forest management planning in Kahayan Tengah FMU. This study aims to model land cover change in 2011 and 2016, predict 2021, and simulate land cover in 2026 in Kahayan Tengah FMU. Modeling land cover prediction and simulation using MOLUSCE from the QGIS plugin. The results revealed that agricultural land experienced significant increase in total area during 2011–2016. Modeling potential land cover transitions in 2011 and 2016 with the Artificial Neural Network method showed a Kappa coefficient of 0.701 in the good category, and simulation of land cover in 2021 with the Cellular Automata method showed a Kappa coefficient of 0.672 in the good category. By 2026, the agricultural land will continue to increase while forest land tends to remain stable in its total area. This study managed to predict land cover in 2021 and simulated 2026 with good accuracy. Thus, this data and information can support forest management planning in Kahayan Tengah FMU. Keywords: forest management unit, Kahayan Tengah, land cover change, land cover prediction, MOLUSCE

Abstract

Host trees are vital for the survival of epiphytic orchids, providing necessary light and air circulation for optimal growth. Large trees with tall canopies contribute to the broader distribution of epiphytic orchids in forest areas. This research aimed to identify the characteristics of orchid host tree species in Lore Lindu National Park, considering both elevation zones and orchid growth zones. The research was conducted at various locations within the park, employing the field exploration survey method (cruise method). This method involved comprehensive exploration at each research site and establishing observation paths along pioneer lines, mainly where orchid host trees were found. The findings indicate the presence of 20 types of orchid host trees and 35 species of epiphytic orchids. The basal branching zone (Zone 3) was the most populated by epiphytic orchids on host trees, and the lowland forest was the elevation zone where most orchid host trees were found in Lore Lindu National Park, Central Sulawesi. Keywords: host trees, Lore Lindu National Park, orchids, zone distribution

Abstract

Perception is an essential factor influencing attitudes and behavior toward the forestry partnership program. Apart from that, a person’s perception can positively or negatively impact the program. The forestry partnerships program is a policy that is the basis of a community empowerment program that provides legal access for local communities to meet the needs of non-timber forest products originating from the Bukit Barisan Selatan National Park (BBSNP) area. The research was conducted to identify the role of partnership members’ perceptions as a mediating variable in achieving goals and obtaining benefits as partnership members in the Semaka Region I National Park Management Sector, BBSNP. Data was collected using a questionnaire, and hypothesis testing was performed using Partial Least Square-Structural Equation Model statistical analysis using SmartPLS 4.0 software. The results showed that perception does not play a mediating variable in achieving goals and obtaining benefits as a member of the partnership. The community benefits from the forestry partnership program if they become members even without having a positive perception of the program. Thus, it is possible that they will not commit properly because the important thing is that they have become members because it will be secure and no longer be considered as an encroachment. This means that it is legal access that makes people want to become members of the partnership. So, to increase positive perceptions and ensure the program’s goal is achieved, namely preserving forests and ensuring the fulfillment of people’s lives, it is necessary to increase the intensity of activities that influence people’s perceptions, for example, socialization, mentoring, and coaching.

Abstract

This study systematically assessed tree species composition and regeneration status within two protected national parks in Bangladesh: Singra National Park and Ramsagar National Park. We employed a stratified random quadrat method across 100 sample plots (50 quadrats from each national park of 10 m x 10 m). Our findings revealed 45 tree species belonging to 25 families. Myrtaceae and Dipterocarpaceae were the most dominant family, having a maximum number of species. We identified 16 exotic species of 10 families and 29 native species of 19 families. Phytosociological parameters like density, frequency, abundance, and importance value index (IVI) were determined. Shorea robusta with an IVI of 47.38 dominated Singra National Park, while Eucalyptus camaldulensis with an IVI of 22.67 was most important in Ramsagar National Park. Regeneration status was good for 15.56% of species, fair for 24.44%, poor for 28.89%, and absent for 17.78%. This study implied the need for collaborative conservation strategies involving policymakers, conservationists, and local communities to ensure the parks’ sustainable eco-custodianship.

Abstract

Forest carbon dynamic modeling for estimating the carbon stock in short rotation coppice bioenergy plantation in Hungary will be vital for better comprehending the role of black locust (Robinia pseudoacacia) and poplar (Populus sp.) in carbon dioxide sequestration from the atmosphere. The research aims were to estimate the potential carbon stock and describe the carbon distribution of the short rotation coppice bioenergy plantation above and below ground. Various sources were used to acquire parameterization data for developing forest carbon dynamic models. CO2FIX modeling V.3.2 was utilized in the data analysis to estimate the total carbon stock in biomass, soil, harvested wood products, and bioenergy compartments. Modeling has been around for 45 years. In this research, the total carbon stock of black locust and poplar at the end of the simulation period was 64.13 and 131.08 MgC.ha-1, respectively. The average carbon allocation above and below ground for black locust and poplar was 0.76, 19.76, 1.80, and 21.67 MgC.ha-1, respectively. In conclusion, poplar outperformed black locust regarding carbon storage in the short rotation coppice bioenergy plantation. Below ground carbon allocation was much higher than above ground. Therefore, more attention should be paid on below ground allocation through environmentally friendly soil management. Keywords: bioenergy plantation, carbon dynamics, climate change mitigation, CO2FIX model, fast growing species

Abstract

Identification of wood species that are difficult to distinguish from their anatomical structure can be done through phytochemical (extractive substance) profiling. This research aimed to analyze the phytochemical profile as a sorter for three species of mangrove wood from Indramayu and Cilacap Regencies, Indonesia, using the liquid chromatography-mass spectrum. The phytochemical markers of taxonomic were the dominant compounds only found in one wood species. The results showed that the three types of wood are dominated by phytochemicals dissolved in ethanol. The results of LCMS analysis of the ethanol extract showed that the phytochemical markers were triterpenoid, flavonoid, and fatty acyls glycoside groups for Rhizophora apiculata, steroid and naphthalene groups for Bruguiera gymnorhiza, and alkaloid as well as fatty amide group for Bruguiera cylindrica. The dominant compounds that characterize these can be used in sorting between mangrove wood species. Keywords: characterizer, compound, mangrove, phytochemicals

Abstract

Magnetic wood with good electromagnetic wave absorption properties was prepared by comparing synthetic and commercial nano-magnetite (Fe3O4-NP) as sengon (Falcataria moluccana) wood impregnation solution. The co-precipitation method produced a synthetic nano-magnetite with NH4OH as a weak base precursor. Meanwhile, the commercial one was purchased from a supplier. Three levels of nano-magnetite concentration (1%, 2.5%, and 5%) were dispersed in deionized water. The impregnation process was done by applying a vacuum of 0.5 bar for 120 minutes, followed by a pressure of 1 bar for 120 minutes. The results showed that the commercial nano-magnetite caused more improvements in weight percent gain, density, and hardness than the synthetic nano-magnetic, although they were insignificantly different. There was also a reduction in brightness with the overall color change being categorized into other colors because the color became darker with increasing nano-magnetite concentration in both woods. The absorbance capacity of the synthetic nano-magnetite-treated wood was larger than the commercial nano-magnetite-treated wood. This synthetic nano-magnetite-treated wood had been optimally treated at a 5% concentration, making it suitable for use as electromagnetic wave shielding material because it can absorb almost 100% electromagnetic waves. Keywords: Fe3O4, impregnation, nano-magnetite, sengon wood, shielding materials
