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

The Indonesian forests occupied the third area in the world with tropical forests as well as donations of rainforests in Kalimantan and Papua. Currently, wood is still the prima in a forestry sector so that the highest income generated by the forest comes to wood shoppers. The destructive logging process can cause damage to the environment. Forest harvesting planning needs to be carried out as an effort to reduce the impact of soil or the upright damage caused by logging. In addition, the use of Reduced Impact Logging (RIL) techniques in forest harvesting are other solutions to reduce the impact of the damage caused by for harvesting activities. This paper is made with the aim of knowing the influence of the use of RIL engineering on the impact of damage caused by forest harvesting activities in tropical rainforests in Indonesia. Data collection is conducted using the literature study method, while the data analysis techniques used are the analysis method for obtaining valid inference and can re-check the context. The results of the literature study indicate that the forest harvesting planning system used in the Indonesian Tropical Rainforests is composed of strategik planning, operational planning, and task planning. Forest harvesting techniques used in the Indonesian Tropical Rainforests consist of Conventional Logging (CL) and Reduced Impact Logging (RIL). The application of RIL techniques has a positive impact on the environment, as it can reduce the upright rate of damage, reducing the level of carbon mass reduction caused by forest harvesting, as well as from the aspects of RIL-eating financial analysis of wood-eating analysis, better than conventional wooden wasteers if the wooden-eating waste is calculated.

Abstract

Gold mining in Sekotong District has raised concerns among the government. This gold mining should not be allowed to continue continuously, because it can disrupt the continuity of the ecosystem. One of the main problems is the disposal of mining waste which has damaged the environment. This article was written using the library research method, namely by codifying scientific sources from various journals and articles with the same data and then combining them to obtain information about the impact of gold mining waste in the Sekotong area, West Lombok, West Nusa Tenggara. The wide distribution of mercury and cyanide is due to the fact that these two chemicals are very efficient in processing gold ore. However, both of them are also chemicals that are very dangerous for the environment. In addition, the distribution of heavy metals resulting from waste from traditional gold mining is greatly influenced by soil conditions, such as temperature and rock disintegration. Various biological and microbiological processes can concentrate metals in the soil, and heavy metal contamination usually accumulates at depths of up to 75 cm above the soil surface. Mercury and manganese waste resulting from gold processing can enter river ecosystems, dissolve in the water, and sink to the bottom of the water, where they will accumulate in sediment. This waste not only settles in sediment, but some of it will also enter the body tissues of biota that live in river waters.
