Abstract

Rattan is one of the commodity timber forest products used as raw material for the rattan industry. One of the small businesses that is quite developed in Rumbai District, Pekanbaru City is the rattan handicraft business which is a traditional small industry and is a family business. This study aims to determine the business feasibility and trading system of the rattan handicraft trade. This research was conducted with a quantitative and qualitative descriptive approach. The method used for data collection is a field survey through observations, interviews, and questionnaires on rattan craftsmen and Trade Units (UD). UD Rattan Crafts in Rumbai can be said to be worthy of continuing. This is because the NPV value of the trading business in Rumbai is > 0, IRR > from interest rates, and BCR > 1. Analysis of the trading system shows that there are trading system functions that are used, namely the exchange function, physical function, and facility function.

Abstract

The waste product left over from pressing or extracting oil palm trunk (OPT) for sugar purposes is known as oil palm trunk bagasse (OPTB). This residue contains mainly vascular bundles and small amount of parenchyma. These materials are potentially utilized for making panel products such as particleboard (OPTBparticleboard). Objective of this study was to evaluate physical mechanical properties of OPTB-particleboard. For preserving the durability, this work was intended to apply 15% mixture of methyl methacrylate (MMA) cured with Styrofoam as the binder with a ratio (w/w) of 3:1. OPTB-particleboard was made according to the Japanese Industrial Standard (JIS A5908: 2003) with a target density of 0.75 g/cm3 and dimensions of 25 x 25 x 1 cm3. Hot pressing was a condition set at a pressure of 30 kg/cm2 and a temperature of 160 °C for 15 minutes. Physical and mechanical properties were tested according to JIS A 5908:2003 standard. The results showed that physical and mechanical properties of the OPTB-particleboard did not meet the standard. The characteristics of OPTB still easily absorb water even though MMA-Styrofoam should hinder water ingress. Additionally, the poor quality of the OPTB-particleboard was primarily due to the binder's inadequate composition. Optimum values reached when IB, MOR, and MOE were 0.026 MPa, 6.69 MPa, and 892 MPa, respectively. Based on the analysis of variance, it can be concluded that there is no influence on the bottom, middle and upper parts of the origin of the OPTB except for the MOR.

Abstract

Tapanuli Orangutan (Pongo tapanuliensis) is a globally critical species (critically endangered) due to the decreasing area of natural habitat. Orangutans can reach out of their natural habitat outside the forest and into community fields for feeding. Orangutans make the other land use not only a place to stopover but also a home range and living area marked by nests. The study aims to obtain information on the characteristics of nests and the estimated population of the Tapanuli orangutan (TO) in the other land-use area. This research method uses line transects placed by systematic sampling with a distance between lines of 3 km and population data analysis using calculations from the van Schaik formula. From the results of the 11 research lines, 14 nests were obtained consisting of 3 class B nests, 5 class C nests, 3 class D nests, and 3 class E nests. The characteristics of the most dominant nests were class C with the most preferred positions II and III and nest finding highest in Quercus maingayi tree. The research found that the density of the TO was eight individuals/1000 ha.

Abstract

The existence of people living around the buffer zone in recent times has led to negative interactions in the form of conflicts between humans and wild animals, one of which is with the Sumatran tiger. The purpose of this study was to identify the sources of livelihood for the community in the buffer area of the Batang Gadis National Park (BGNP), and calculate the total economic losses suffered by the community due to human and wildlife conflicts in the buffer area of the national park. This study used a survey method, data were collected through interviews with selected respondents based on purposive sampling method with snowball technique. Data analysis is done by descriptive analysis. The results of the research show that the source of livelihood for the people living around the TNBG area is mostly farmers. The community's perception of the disturbance of wild animals and Sumatran tigers in Hutabaringin Julu Village and Bangkelang Village is that some people consider wild animals or Sumatran tigers to be beneficial to them in the balance of nature, and some others consider wild animals to be no useful in life because they are considered to disturb community plantation lands. The tiger conflict caused an economic loss of IDR 14,400,000 in Hutabaringin Julu Village and Bangkelang Village of IDR 35,280,000.

Abstract

The Universitas Sumatera Utara has various types of trees scattered in the surrounding environment. Swietenia macrophylla, Mimusops elengi and Polyalthia longifolia are the three most common tree species found on campus. To maximize the potential for utilizing tree species on the Universitas Sumatera Utara campus, several efforts can be made, one of which is by exploring the presence of cellulolytic fungi. Cellulolytic fungi are fungi that are able to hydrolyze cellulose which can produce cellulase enzymes. This study aims to obtain the potential and identify cellulolytic fungi from the soil under Swietenia macrophylla, Mimusops elengi and Polyalthia longifolia stands. Sampling was taken by making 3 plots on each type of stand measuring 20 m x 20 m with a soil depth of 0 – 20 cm. In each plot, 5 sampling points were made. The soil taken from each type is then composed. Isolation of cellulolytic fungi was carried out using Carboxy Methyl Cellulose (CMC) media. The potenstial of cellulolytic fungi is obtain by calculating the cellulolytic index. All isolates obtained were identified morphologically down to the genus level. The result showed that the potency of the cellulolytic fungi ranged from 0.05 to 1.36. The identification results that the isolates included the genus Aspergillus and Trichoderma.

Abstract

Forest fragmentation is a threat to ecosystems in Indonesia caused by forest conversion to plantations. This study aims to analyze the use of land cover in the period 2013-2022. The research was conducted from November 2022 to January 2023 in the Gayo highland area by taking case studies in 2 regions including the Central Aceh District and Bener Meriah District. The research was carried out in several stages, namely: image pre-processing, image visual interpretation, making image classification class identifiers, and ground checking. The pre-processing stage is the preparation of tools and materials. Landsat 8 OLI imagery for the study area downloaded from the United States Geological Survey (USGS) website. The results of the research show that in the last 10 years there has been a decrease in the area of land cover in the exploration area of primary forest and secondary forest. Meanwhile, in the cultivation of dry fields, settlements, plantations and vacant land, land use has increased. Changes in the use of land cover are influenced by community activities in Central Aceh and Bener Meriah Regencies.

Abstract

City development with unfriendly development causes the quality and quantity of open green space to decrease. Google Earth is an interactive mapping application released by google, which displays a digital visualization of the geographical shape of the earth. This study aims to determine the type and quality of trees on the urban forest in the Tanjung-Morawa sub-district and to map the quality of trees on the urban forest in the Tanjung-Morawa sub-district. This study uses a modified method of tree quality assessment with two criteria: tree health and technically criteria. From the observation result, there are 18 trees, Glodokan (Polyalthia longifolia) with the highest number, as many as 842 trees, and Dadap Merah (Erythrina crista goly) as the tree with the least amount. The quality of the trees in the urban forest shows a moderate good quality, where the highest health is in the medium category and for the technical in the low category. Trees that are recommended to be cut have a cumulative ≥ 2,5 Angsana trees with a total of 129 trees, and the highest cumulative percentage is the Banyan tree at 66,67%. The Mango tree has the lowest rate at 8,70%. Google Earth can’t be used optimally because of the low-resolution image quality. Image capture data in google earth has not been updated; the unstable internet connection and the time of the retrieval and processing of field data are not the same as the time retrieval and processing.

Abstract

Life cycle assessment (LCA) is a tool to analyze the environmental impact of the process of production or services. Forest provides enormous environmental benefits through ecosystem services, but some forest management activities (nursery, thinning, pruning, pest control, and harvesting) have produced some negative impacts, such as pollution from machine utilization, fertilizer and pesticide, and water consumption. Furthermore, this paper describes the application of LCA in the forestry sector in Indonesia. We used the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) approach to identify, screen, and inclusion the relevant articles. Identified 35 articles related to life cycle assessment in Indonesia's forestry sector, and only 11 articles were eligible for content analysis. The findings have shown that the research trend on LCA in the Indonesia forestry sector started in 2009, but since 2015 the number of publications has been relatively constant. The functional unit used in LCA varied (mass, energy, time, and area size). The system boundary also varied  from cradle to gate, gate to gate, and cradle to grave. The environmental impacts found in the articles were global warming potential, acidification, and eutrophication parameters. In conclusion, LCA has been applied in Indonesia’s forestry sectors (roundwood production, furniture industries, biomass and wood pellet production). We propose that the future research direction is specific research in the site forest operation, such as seedling production, forest maintenance, and forest harvesting activities. We also recommend a more varied research scope to elaborate the LCA in private forest and non-timber forest product processes.

Abstract

One of the influential factors in the success of beekeeping is the availability of bee feed. Beekeepers need to know the types of food sources for bees and have a map of the sources of nectar and pollen in their area. This will help in planning the management of their colony. This research was conducted to identify the types and flowering of bee feed plants (Apis cerana) and to determine honey production. In this study used exploratory survey methods and interviews. Based on the study's results, there were 17 identified types of bee feed sources from forestry plants, 13 identified plant species from crops and 6 identified plant species that produce flowers. The flowering schedule for honey bee feed plants in Pakpak Bharat Regency for Kaliandra plants blooms in February - July, for Durian plants blooms in March, April - October, and November for Coffee plants flowers in April and August. Honey production in Pakpak Bharat District has a different frequency of harvest and production each month. For April, 11 members produced 42 bottles of honey. For May, 10 members produced 55 bottles, where the size per bottle was 600 ml.

Abstract

Mangrove forests in Pasar Rawa Village have experienced degradation and damage due to activities changing the function of forest areas into oil palm plantations and fish farms. To overcome this, community participation is key in evaluating forest and land rehabilitation (FLR) as a step to restore, preserve, and improve the function and productivity of these forests and land. This research aims to analyze the level of participation and the determination of a set of criteria and indicators for the success of FLR evaluation. This research uses the method scale Likert to determine the level of community participation, and multicriteria analysis is used to choose a set of criteria and indicators for the success of FLR evaluation. This research shows that community participation in planning, implementation, monitoring, and post-planting activities received a high category, and the FLR success rate was 82.3%, including the "good" predicate. This is due to the heightened awareness of the importance of protecting mangrove forests. However, it is still necessary to improve FLR activities in the future so that the mangrove forest in Pasar Rawa village remains sustainable.
