Abstract

The vegetation profile is a vertical and horizontal description as well as the structure and species composition of a vegetation which includes the dominance of canopy cover, species diversity, species dominance, species frequency, species density and undergrowth. This research aims to obtain an overview of the composition, vertical and horizontal structure of vegetation so as to provide information about tree dynamics and ecological conditions as well as to view tree architectural models. The method for collecting community profile data is carried out in each sample plot measuring 20x20 m with data requirements such as: trunk diameter at DBH height, tree height, tree height, canopy limit, and tree canopy projection. Based on data on tree height and diameter, it was concluded that the trees in the research plot area were trees of the past because they had a total height of between 20-54 meters with a trunk diameter of ±1.63 meters. the results of drawing architectural profiles of tree canopy projections horizontally and vertically so that we can see models of canopy closure and competition for sunlight in homogeneous forest tree communities consisting of the Agathis loranthifolia species. The results of the horizontal and vertical projection of the architectural profile of the tree canopy can be seen so that the model of canopy closure and competition for sunlight in a homogeneous forest tree community consisting of the Agathis loranthifolia species can be seen. The ecological function of the Agathis loranthifolia type is very good in maintaining the environment, related to groundwater storage which can reduce the impact of soil erosion rates. Certain tree architectural models influence the transformation of rainwater into stem flow rate, water through the canopy, infiltration and surface flow rate in an area which is related to the role of vegetation as disaster mitigation.

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.

Abstract

The diversity of vegetation can reflect the vegetation structure of an area against information on species composition, distribution patterns, density patterns, frequencies, and species dominance to determine the important value index of the forest community composition of a plant species. This study aims to analyze understory vegetation in the IPB Dramaga Campus Forest using two main methods, namely line intercept and point intercept. Both methods are applied to compare the effectiveness of measuring ecological parameters such as density, frequency, dominance, and understory diversity index. The results showed that there were 10 types of plants with the line intercept method including Digitaria fuscencens, Spilanthes paniculata, Cleome vicicosa, Clitorea Ternatea, Digitaria longifora, Britaria reptans, Ageraitum conzoides, Imperacta clindraca, Hevea braziliensis, Paku. Meanwhile, in the tangent point method, 5 species were found at the research method line points as follows: Digitaria fuscencens, Spilanthes paniculata, Clitorea Ternatea, Digitaria longifora, Altherenthera philoxeoriides. The analysis of the importance value index in the tangent line method showed that Spilanthes paniculata dominated the understory vegetation with an importance value index of 145.91%, followed by Digitaria fuscencens (48.39%) and Digitaria longifora (40.58%). Meanwhile, in the tangent point method, Digitaria fuscencens had the highest importance value index of 69.46%, followed by Spilanthes paniculata (69.20%) and Clitorea ternatea (40.65%), with the lowest importance value index of Digitaria longifora (16.52%) and Altherenthera philoxeoriides (7.17%). The tangent line method is more effective in describing the horizontal distribution of vegetation, while the tangent point method provides high precision in estimating relative cover. The understory vegetation in this area is dominated by certain species that have high adaptation to the IPB University campus forest environment.

Abstract

Gunung Walat Educational Forest is one of the ecosystems rich in biodiversity, including understory plants that play an important role in maintaining the ecological balance of the forest. This study aims to analyze understory vegetation in Gunung Walat Educational Forest using the line intercept method. This method was chosen because of its effectiveness in measuring the diversity, dominance, and distribution of understory plants in natural habitats. Data were collected by recording the types of plants that crossed the transect line, supplemented by measurements of density, frequency, and relative cover. The results showed that 16 types of understory plants were found in homogeneous and heterogeneous forest ecosystems including: Aghatis damara, Arenga undulatifora, Cinnanonum cintoc, Homalonema sp, Hornstedtia pinanga, Leea aquata indica, Melastoma malabathricum linn, Palmae, Pandanus furactum, Pinanna curunarri, Piper nigrum, Selaginella doederlinni, Shorea sp, Strubilentes crispus, Tetrastigma lanceolarium, and Zingiber zerumbe. The results showed that the number of understory plant species found in heterogeneous forests was higher than in homogeneous forests, with 17 and 15 species respectively. In homogeneous forests, the Selaginella doederleinii species dominates quantitatively with the highest relative density (46.26%), the highest relative frequency (39.70%), and the highest dominance (42.76%). This causes Selaginella doederleinii to have the highest important value index (INP) of 128.74%, followed by Tetrastigma lanceolarium (68.62%) and Homalonema sp (17.92%). The biodiversity of homogeneous forests in GWUF shows a high species diversity index (H’), which is an average of 4.27 with a species evenness of 1.45.
