This study is an attempt to determine the level of vegetation density resulting from the 2017 RHL planting in Gunung Malang Village. The study method for evaluating the plant density index is done by determining the number of sample plots based on Stratified Random Sampling is a technique used to determine the number of samples, if the population is stratified but not proportional. Taking into account the determination of the sample based on the potential of the arable land which then classified by taking three criteria, namely the potential with high, medium, and low levels which are classified based on secondary vegetation data of the cultivators. Data collection was carried out using a census inventory with Plot Samples were taken based on the area under cultivation. The results of the plant evaluation are then processed by calculating the density level index formula which is analyzed to obtain the value of Density and Relative Density (KR) to determine the density level of the area so that conclusions can be drawn. The results of the study show that the results of the analysis of the 2017 RHL vegetation density level of the remaining number are only 103 tree stands at this time with a density value of 2.4772 or (2.48%) with a relative density of 1 or (100%). From the results of the RHL density analysis, the density level was relatively low when compared to the number of seeds planted. With the current remaining stands, the percentage of growth is less than 75% of the total number of seedlings planted, so this RHL activity can be said to be unsuccessful based on PermenLHK No. 2 of 2020.

Climate change is constant. The average temperature has risen since the globe was encased in ice millions of years ago. Current climate change is caused by natural events and human behavior in treating and managing the environment. The huge burning of coal, oil, and wood and deforestation caused by economic development has seriously damaged the world's climate. Global climate change may alter peat carbon stored by forest and land fires. Human activities like plantation development, agriculture, and logging have made tropical peatlands more vulnerable to fire. Indonesia has 44 million hectares of tropical peatlands, with 45% and 64% carbon content. This study addresses Palangka Raya's intermittent land surface heating. The Palangka Raya University academic community conducted this research to provide input on climate change and the global environment and to predict a symptom or occurrence that harms society. This project is part of the University of Palangka Raya's Principal Scientific Pattern (PIP): Science and Technology Innovation in Tropical Peat Swamp Areas and River Streams.

In supporting a systematic and comprehensive Strategic Environmental Assessment of the detailed spatial planning (RDTR) and Zoning Regulations (PZ) of the technical documents in the City Planning Area Section (BWP). It is necessary to understand the threat of hydrometeorological disasters, especially floods and waterlogging. Therefore, it is necessary to study the hydrological boundaries and distribution of water flow. In supporting optimal urban planning, this research was carried out on the BWP RDTR of Kasongan City, Katingan Regency periods 2020-2040 which has an area of 4,639.98 Ha. The research was carried out in August-November 2022, by delineating Micro-watersheds (sub-sub-sub watersheds) in and around the Kasongan City BWP followed by carrying out 2D simulations of water flow and inundation. The results of the study show that the BWP RDTR and PZ of Kasongan City are overlaid with Micro DAS as ecological boundaries in the form of hydrological unit polygons, showing as many as 59 polygons are affected areas with an area of 10,413 Ha. The area includes the Salangaju, Salangawa, Katunen and Liting watersheds with a polygon area ranging from 1 to 617 Ha, with an average polygon area of 179.53 Ha. Thus, the ratio between the area affected and the area of BWP and PZ is 2.24%. In the Main Program Indications, there are areas that are indicated to be experiencing a threat of flooding and inundation.

The Sumatran elephant (Elephas maximus sumatrensis) is a rare animal that is threatened with extinction, so conservation is needed. Elephant Training Center (PLG) Way Kambas National Park is one form of in situ conservation. The availability of natural food is one of the factors that determine the success of conservation. The purpose of this study was to determine the composition and diversity of forest community species as elephant feeding habitats, and to determine the types of plants that elephants eat. Purposive sampling was used to collect data using nested plots, 1 x 1 m2 for seedlings and undergrowth, 5 x 5 m2 for saplings, 10 x 10 m2 for poles and 20 x 20 m2 for trees. The results showed that the vegetation making up the forest as a grazing habitat for Sumatran elephants consisted of 27 species belonging to 19 families. The vegetation that elephants eat is Symplocos thwaitesii, Imperata cylindrica, Colopogonium sp., Bridelia monoica, Vitex pinnata, Shorea sp., Pennisetum purpureum, Gluta renghas, Mimosa pudica, and Melastoma. The most widely available plant species belong to the Poaceae and Leguminoceae families. The diversity index of the seedling level of 2.49 was categorized as high, while the vegetation level of sapling, poles, and trees was categorized as low. Meanwhile, the evenness index at the seedling, sapling, pole and tree levels was categorized as high. The richness index for all levels of growth is categorized as moderate.
