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

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

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.

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.

观念是影响人们对林业合作伙伴计划的态度和行为的重要因素。除此之外，个人的认知也会对计划产生积极或消极的影响。林业合作伙伴计划是一项社区赋权计划的基础政策，该计划为当地社区提供合法途径，以满足对源自武吉巴里桑雪兰莪国家公园（BBSNP）地区的非木材林产品的需求。本研究旨在确定伙伴关系成员的看法作为一个中介变量，在实现目标和获得收益方面所起的作用，因为伙伴关系成员是 BBSNP Semaka 地区 I 国家公园管理部门的成员。数据收集采用问卷调查法，假设检验采用 SmartPLS 4.0 软件的部分最小平方结构方程模型统计分析法。结果表明，感知并不是实现目标和获得利益的中介变量。如果社区成为林业合作伙伴计划的成员，即使他们对该计划没有积极的认知，也能从该计划中获益。因此，他们有可能不会做出适当的承诺，因为重要的是，他们成为成员后将会得到保障，不再被视为侵占。这意味着，合法的准入才会使人们愿意成为伙伴关系的成员。因此，为了提高人们的积极看法，确保项目目标的实现，即保护森林和确保人们生活的满足，有必要提高影响人们看法的活动的强度，例如社会化、指导和辅导。

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.

Mangrove forests on small islands play an essential role in the stability of island ecosystems. It is crucial to analyze the performance of local institutions in forest management to increase the community’s active role in preserving mangrove forests. This research aims to analyze the performance of local institutions managing mangroves on small islands. The research was conducted on Buano Island, Maluku, Indonesia. In-depth interviews and participant observation were used to obtain data. Data analysis uses a Situation, Structure, Behavior, and Performance (SSBP) approach. The research results show that the community is very dependent on mangrove forests. Resources are owned by the clan group (Soa) but managed by members of the clan group (family). Thus, the phenomenon occurs when common pool resources are managed by private (Dati/Nuru) proprietors. The community regulates the utilization of potential forest resources by dividing management areas controlled by each Soa/Nuru group. The preservation of natural potential on Buano Island is supervised by Kewang and Sasi culture. Applying customary rules increases the community’s active role in managing resources and supporting village management. However, mangrove forest logging activities continue to occur. This performance shows a very high decline in mangrove forest vegetation and regeneration of mangrove forests. Stakeholder support is needed to increase the knowledge and skills of the community, especially traditional leaders, in implementing sustainable forest management.

小岛屿上的红树林对岛屿生态系统的稳定起着至关重要的作用。分析当地机构在森林管理方面的表现，以提高社区在保护红树林方面的积极作用，是至关重要的。本研究旨在分析管理小岛屿红树林的地方机构的绩效。研究在印度尼西亚马鲁古省布阿诺岛进行。研究采用深入访谈和参与观察的方式获取数据。数据分析采用了情景、结构、行为和绩效（SSBP）方法。研究结果表明，该社区非常依赖红树林。资源归氏族群体（Soa）所有，但由氏族群体（家庭）成员管理。因此，出现了公共资源由私人（Dati/Nuru）所有者管理的现象。社区通过划分每个 Soa/Nuru 族群控制的管理区域来管理潜在森林资源的利用。布阿诺岛的自然潜力保护工作由 Kewang 和 Sasi 文化负责监督。习惯规则的应用增强了社区在管理资源和支持村庄管理方面的积极作用。然而，红树林砍伐活动仍在继续。这一情况表明，红树林植被和红树林再生的下降幅度非常大。需要利益相关者的支持，以提高社区（尤其是传统领袖）在实施可持续森林管理方面的知识和技能。 关键词：森林管理；地方机构；红树林；小岛屿

Agroforests in many tropical countries have long been acknowledged as substantially necessary to contribute to biodiversity conservation and community livelihood. The importance of agroforest biodiversification is now overlooked and replaced by a simplified structure due to the impact of agricultural commercialization. Land use changes have occurred in the Upper Citarum Watershed over time, converting traditional agroforests into monoculture plantations at the expense of their socio-ecological function. This paper aimed to analyze land use change dynamics and the effect of biodiversity loss on the socio-economy aspect of the rural agricultural landscape in the Upper Citarum Watershed. We conducted a survey of 95 respondents of community farmers in the agricultural landscape in Sukapura and Resmi Tingal Village using questionnaire guidelines and direct interviews to gather information. There was a significant decrease in plant diversity in some plot agroforests, which, in the previous study, was dominant to be reduced even to local extinctions. The results also show that the farmer poverty index according to BPS criteria is 12.63% of respondents who are below the poverty line. Our results imply that preserving mixed-garden (talun) patches in a landscape dominated by cash-crop gardens is one of the strategies that could conserve landscape biodiversity and increasingly a sustainable livelihood.

Malabayabas (Tristaniopsis decorticata (Merr.) Peter G. Wilson & J.T. Waterh.) of the Myrtaceae family is a vulnerable endemic tree species in the Philippines. Poor development and low regeneration rates of seedlings in their natural habitats have led to a considerable population decline of the species. This study aimed to determine the morphological and physiological growth responses of T. decorticata seedlings in different soil media inoculated with arbuscular mycorrhizal fungi applied once at a rate of 5 g per seedling for the entire duration of the experiment. Morphological parameters were collected using conventional methods, while physiological parameters were measured using LI-6400 XT Portable Photosynthesis System. Results of the study revealed that the morphological growth of seedlings was generally better in Bantay soil regardless of treatments than in Lipa soil. Interestingly, the net photosynthesis, transpiration rate, and water-use efficiency were generally higher in Lipa unsterilized soil inoculated with arbuscular mycorrhizal fungi. However, this study can not yet confirm the percentage of Arbuscular Mycorrhizal Fungi (AMF) root colonization. Thus, further research must be conducted to determine the AMF root colonization and identify potential indigenous mycorrhizal fungi in both soil media.

Waterh.）是菲律宾一种脆弱的特有树种。在其自然栖息地，幼苗发育不良且再生率低，导致该物种的数量大幅下降。本研究旨在确定 T. decorticata幼苗在不同土壤介质中的形态和生理生长反应，这些介质接种了丛枝菌根真菌，试验期间每株幼苗施用一次，每次 5 克。形态参数采用传统方法收集，生理参数采用 LI-6400 XT 便携式光合作用系统测量。研究结果表明，与 Lipa 土壤相比，Bantay 土壤（无论何种处理）中幼苗的形态生长普遍较好。有趣的是，在接种了丛枝菌根真菌的未灭菌 Lipa 土壤中，净光合作用、蒸腾速率和水分利用效率普遍较高。不过，这项研究还不能确定丛枝菌根真菌（AMF）的根定殖率。因此，必须开展进一步的研究，以确定这两种土壤介质中AMF根的定殖率，并确定潜在的本地菌根真菌。

Waterh.) of the Myrtaceae family is a vulnerable endemic tree species in the Philippines. Poor development and low regeneration rates of seedlings in their natural habitats have led to a considerable population decline of the species. This study aimed to determine the morphological and physiological growth responses of T. decorticata seedlings in different soil media inoculated with arbuscular mycorrhizal fungi applied once at a rate of 5 g per seedling for the entire duration of the experiment. Morphological parameters were collected using conventional methods, while physiological parameters were measured using LI-6400 XT Portable Photosynthesis System. Results of the study revealed that the morphological growth of seedlings was generally better in Bantay soil regardless of treatments than in Lipa soil. Interestingly, the net photosynthesis, transpiration rate, and water-use efficiency were generally higher in Lipa unsterilized soil inoculated with arbuscular mycorrhizal fungi. However, this study can not yet confirm the percentage of Arbuscular Mycorrhizal Fungi (AMF) root colonization. Thus, further research must be conducted to determine the AMF root colonization and identify potential indigenous mycorrhizal fungi in both soil media.\u0000Keywords: arbuscular mycorrhizal fungi, endemic, net photosynthesis, transpiration rate, Tristanipsis decorticata","PeriodicalId":510592,"journal":{"name":"Jurnal Sylva Lestari","volume":"111 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140250614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
