Abstract

Forests are one of the natural resources that can be utilized in the form of both wood and non-wood forest products. Harvesting carried out to extract wood results in negative impacts such as soil damage and damage to standing stands. The negative impacts of wood harvesting can be reduced by planning in advance, such as creating a forest road network. The research was carried out in the mahogany room, utilization division, forest management department, while the assessment of the forest road network used the case study of PT Inhutani I Lebanan. The aim of the research is to examine the planning and selection of the best alternative forest road network for harvesting wood using multi-criteria decision making techniques. The research will be carried out in March 2023. The research stage begins with sketching the road network; assess road networks using economic, ecological and technical criteria; as well as conducting literature studies from various sources. The research results show that there are six alternative forest road networks for harvesting wood. This is based on forest road network assessment parameters that the best alternative road network in the PT Inhutani I Labanan road scheme is the 6th road network alternative. Sustainable management of forest resources can be achieved through a well-planned road network. The highest total utility value (rank 1) is found on the 6th road network which is the best alternative forest road network to be implemented at PT Inhutani Labanan I both in terms of technical aspects, ecological aspects and economic aspects.

Abstract

This study aims to determine the potential location of seed gardens in the HPH area of ​​PT ITCI, East Kalimantan, through spatial data analysis based on Geographic Information Systems (GIS). The main data used is the Digital Elevation Model (DEM) which has been converted from the Triangulated Irregular Network (TIN) form to raster for surface analysis purposes. The analysis process includes slope classification into five classes, area cutting (clip), raster data regrouping (reclassify), conversion to polygon form, and spatial overlay using the buffer and intersect functions. The results of the analysis show that areas with gentle slopes (8–15%) dominate the study area with an area of ​​67,533.45 ha, followed by flat areas (0–8%) covering an area of ​​20,751.28 ha. Buffer analysis was carried out on rivers (150 meters) and roads (1,000 meters) to limit the management area, then continued with intersect operations to combine spatial variables such as the number of trees, level of stand damage, and administrative boundaries. Based on technical criteria, namely the number of trees more than 30 trees per hectare, minimal damage level, slope less than or equal to 15%, and a minimum area of ​​2 hectares, 30 land units were obtained that met the requirements as seed garden locations, with areas varying between 2 and 46 hectares. The three selected locations are the result of the integration of all land suitability parameters spatially.
