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 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.

Abstract

This study aims to analyze the effect of allelopathy from leaf extracts of Acacia auriculiformis and Melia azadirachta on the germination of mung beans (Vigna radiata). Alleleopathy is a biological phenomenon in which chemical compounds released by certain plants affect the growth and development of other plants. This study used an experimental method with various concentrations of leaf extracts of the two tree species (0%, 10%, 20%, and 40%). The parameters observed included germination percentage, growth rate, root length, and mung bean bud length. The results showed that the increase in the concentration of Acacia auriculiformis and Melia azadirachta leaf extracts  significantly inhibited the germination process and early growth of mung beans. Allelopathic compounds such as flavonoids, tannins, and total phenols are thought to be the main cause of the barrier. Growth and development in acacia leaf extraction (Acacia auriculiformis) showed that the growth and development of green bean seeds experienced rapid growth, even exceeding growth in the control treatment. The difference in concentration in the analysis of further tests of neem leaf extraction and acacia gave a quite significant effect, in acacia leaf extraction there was no major effect on germination, but in neem leaf extraction on green beans which was given a negative effect on germination which at a concentration of 40% was much slower compared to other concentrations.

Abstract

This study aims to analyze the intraspecific competition between peanuts (Arachis hypogaea) and corn (Zea mays) in a controlled environment in the Green House IPB University, Bogor, West Java. Intraspecific competition occurs when individuals of the same species compete with each other for limited resources, such as light, water, and soil nutrients. This study was conducted using a factorial experimental design, involving various levels of planting density in each species. The observed parameters include plant growth, biomass, competition index, and crop yield. The results showed that the interaction between peanuts and corn under intraspecific conditions affected the efficiency of resource use as well as the yield of each plant. These findings provide important insights for the management of mixed cropping patterns, especially in sustainable agricultural systems that prioritize land and resource use efficiency.

Abstract

Several species of weeds, categorized as invasive plants, are among the factors inhibiting plantation productivity. The uncontrolled spread and growth of these invasive plants can lead to both economic and ecological losses. This study aimed to analyze the diversity of invasive species in the palm oil plantation area of PT Perkebunan Nusantara II. Plant samples were collected by establishing sample plots in three different blocks using purposive sampling. Additionally, species identification and data analysis were conducted, including the Important Value Index (IVI), diversity index, similarity index, and evenness index. A total of 20 invasive species out of 61 weed species, belonging to 14 families, were identified. The invasive species are primarily herbs, climbing plants, and shrubs. Invasive species are dominated by families Poaceae and Asteraceae. Asystasia gangetica, Mitracarpus hirtus, Peperomia pellucida, and Phyllanthus urinaria were found in all three blocks. However, based on the IVI value, only three invasive species were found to significantly affect the community: P. urinaria, Setaria plicata, and P. pellucida.

Abstract

Oil palm requires sufficient water for optimal growth. However, oil palm plantations in Indonesia face the challenge of global climate change, which causes increased temperatures and unpredictable rainy seasons. The research aimed to analyze oil palm accessions from Jambi that are tolerant to drought based on plant morphophysiological characteristics and metabolite profile. The experiment was conducted in the greenhouse using a factorial randomized block design. Five oil palm accessions were evaluated in this study, i.e., Muara Jambi (MJ), Tebo (TB), Tanjung Jabung Barat (TJB), Merangin (MR), and Simalungun (SM). Seedlings were planted in pots containing 20 kg of soil and acclimatized for 14 days before treatment. Drought treatments were carried out for two, four, and six weeks. Observations were made on growth, physiological, and metabolite changes at the end of each drought period. The study showed that the SM accession exhibited a higher photosynthetic rate and fresh and dry biomass than the other accessions. However, the content of proline and MDA increased significantly in oil palm throughout the drought periods. Metabolomic profiling revealed a significant increase in 13 metabolites under drought stress, i.e., citramalate, L-tyrosine, ferulate, and 3-4-dihydroxybenzoate were the four most prevalent metabolites in the leaf. The root produced more L-proline, aspartate, aconitate, kaempferol-3-o-pentoside, oxoadipate, citrate, L-phenylalanine, maltose, phenylacetic acid, and citramalate. These metabolites have roles in plant metabolic pathways such as valine, leucine, and isoleucine biosynthesis, phenylpropanoid biosynthesis, arginine and proline metabolism, citrate cycle (TCA cycle), lysine biosynthesis, phenylalanine metabolism, and starch and sucrose metabolism.

Abstract

The purpose of this study was to determine the utilization and cultivation of myrmecophytes as medicine by the community in Bengkulu Province. The sampling of this research was conducted through interviews with 5 key informants and 50 respondents using purposive sampling method and direct observation in the field, literature study and documentation. The results of the interviews were then analyzed descriptively to determine the utilization and cultivation of myrmecophytes as medicine by the community in Bengkulu Province. The results showed that there are two species of myrmecophytes namely Hydnophytum formicarum and Myrmecodia tuberosa in Bengkulu Province. These myrmecophytes is utilized by the people of Serawai, Rejang, and Lembak tribes for various types of diseases such as headaches, diabetes, tumors, aches, joint pain, cancer, rheumatism, high blood pressure, jaundice, vaginal discharge, back pain, and hepatitis. The myrmecophytes is also commercialized by the community by chopping and drying. The community that uses myrmecophytes also cultivates the plant using traditional methods such as placing it in coconut fiber, giving it soil media, and hanging it on trees in the residents yards. Information about the ethnobotanical study of myrmecophytes is expected to be known by the community in Bengkulu Province at large so that this plant can be recognized as a medicinal plant and an alternative to traditional medicine.

Abstract

The 2010 eruption of Mount Merapi caused the ecosystem of Mount Merapi National Park had damage. The recovery of the surrounding ecosystem was called succession . Soil seed bank can be a seed resource for the succession. This research was conducted to analyze vegetation composition and explore the potential seed bank of understorey plants. The vegetation analysis was done using a quadratic method in the three locations: highly damaged, moderately damaged, and lightly damaged. A 1×1 m2 plot was used to collect 9 soil samples from each location. The soil samples were stored in a greenhouse for the germination test. Results showed that Poaceae dominated the vegetation in three locations. The vegetation in moderately and lightly damaged locations has a higher score in diversity and evenness than that in highly damaged locations. The seed bank results showed approximately 34 understorey plants from 14 families dominated by Poaceae. The similarity between the standing aboveground vegetation and soil seed banks in the three locations was low.
