The way to identify vegetation types is by identifying plant morphological features. This study aims to identify the distribution of pole and tree-level woody plant species and analyze the types of pole and tree-level stands in Pandamaran Hill. The research method uses vegetation analysis by sampling to obtain the Important Value Index (INP), Species Diversity Index (H'), Type Evenness Index (e), Dominance Index (C), Community Similarity Index (IS), RAL for the ANOVA test of the influence of place height on the number of plants and identification of pole and tree level plant species. The vegetation analysis plot used is 20 m x 20 m, in it there is a plot measuring 10 m x10 m which is made as many as 3 paths with a division per height down (125-150 Masl), middle (150-175 Masl), upper (175-200 Masl) each 6 plots per path so that a total of 18 plots for 3 paths. The results of this study show that the highest INP value is dominated by types, H value' level of poles and trees per height of the place is classified as medium, the value of e level of poles and trees per height of the place is classified as almost evenly distributed, the value of C the level of poles and trees per height of the place is classified as medium-high, the ANOVA test with an interval of 25 masl for the influence of the height of the place on the number of plants does not differ markedly and  For the identification of plant species, 10 types of poles and 19 types of trees with their respective distributionsPengenalan dan analisis vegetasi yang tumbuh di alam seperti Bukit Pandamaran kawasan KHDTK Universitas Lambung Mangkurat menjadi hal yang penting agar pemanfaatan hutan dapat dilakukan dengan optimal. Cara pengenalan jenis vegetasi yaitu dengan mengidentifikasi ciri morfologi tumbuhan.

Therefore it is necessary to improve vegetation in protected forest areas, but before making improvements by planting, it would be better to first know the local species that grow and develop in the protected forest area of Gunung Keramaian. This study aims to determine the composition and structure of the vegetation. The method of determining the Starting Point for the placement of observation plots used purposive sampling. Processing of data to determine the composition of vegetation types and to determine the structure of the vegetation used an important value index (INP), and an analysis of the diversity and evenness indices.

Indonesia is ranked 1st in the world's palm oil producer with 47,120,247 tons and 1st in the world's palm oil area with an area of 14,456,611 ha. One hectare of oil palm plantations in South Kalimantan has the potential to produce 4.4 million tons in one year. The dry frond waste from the pruning of oil palm can be used for processing biobriquettes. This study purpose to obtain the moisture content, ash content, volatile matter, calorific value, and burning time of the biobriquettes of oil palm fronds produced based on particle size. The results of the biobriquette waste from oil palm fronds in this study contained a moisture content of 7.20% - 12.60%, ash content of 3.60% - 8.54%, volatile matter 34.85% - 55.12%, a value of 34.85% - 55.12%. the heat is 3,020 cal/g – 5,091 cal/g, the burning time for smoldering is 61 minutes – 74 minutes, and the burning time for boiling 500ml water is 18 minutes – 25 minutes. The results showed that the particle size affects the quality standards of briquettes and burning time. The lower the moisture content and ash content, higher the calorific value so fast that the boiling water is 500 ml. The best results were found in treatment C with a particle size 80 mesh with an average the calori value of 4.952 cal/g.Pemerintah Indonesia mempunyai target pada tahun 2025 yaitu penggunaan bauran etb sebesar 23% yang tertuang pada RUEN.
