Kajian ini dilakukan di Kampung Ujoh Bilang, Kecamatan Long Bagun, Kabupaten Mahakam Ulu. Peningkatan jumlah penduduk yang semakin cepat akan berpengaruh pada peningkatan kebutuhan hidup baik secara kuantitas maupun kualitas terhadap penggunaan tanah. Hal tersebut juga berpengaruh terhadap kebutuhan akan lahan untuk berbagai kepentingan manusia yang semakin lama semakin meningkat sehingga terjadi perubahan fungsi lahan. Penelitian ini dilakukan untuk memprediksi nilai erosi dengan menggunakan Metode USLE. Metode tersebut digunakan untuk menilai kehilangan tanah akibat erosi. Parameter yang dianalisis terdiri dari faktor erosivitas limpasan (R), erodibilitas tanah (K), panjang dan kemiringan (LS), pengelolaan tanaman dan konservasi tanah (CP). Berdasarkan data analisis diketahui bahwa Tingkat Bahaya Erosi lokasi penelitian memiliki kategori sangat berat dengan nilai 75,55 ton/ha/th. Perencanaan konservasi pada kawasan tersebut dengan mempertahankan kondisi tanaman penutup tanah dan tetap melakukan penanaman tanaman penutup tanah, sistem penanaman tumpang sari, pembuatan teras gulud searah garis kontur serta pembuatan teras saluran.

Balikpapan is a city in East Kalimantan, Indonesia, serving as a business and industrial center with the largest economy on the island of Kalimantan. The Teritip Dam has multiple purposes, including flood control and addressing the clean water crisis caused by a lack of raw water sources. The demand for clean water will continue to increase with population growth. This study aims to determine the contribution of the Teritip Dam in meeting the community's clean water needs through the Regional Drinking Water Company (PDAM) of Balikpapan. The study also seeks to provide input for potential contributions and conservation efforts. The analysis of domestic clean water demand involves evaluating the condition of clean water, identifying the supply and demand of clean water, analyzing population projections, and estimating the volume of clean water needed by the population. The study findings indicate that the Teritip reservoir provides a discharge of 8,891 m3/day, fulfilling only 14.3% of the clean water demand in Balikpapan. Therefore, implementing water resource conservation measures is crucial to meet the water demand in Balikpapan. These conservation activities include improving the supervision of water withdrawal and usage by considering conservation interests, raising public awareness about water issues, and controlling groundwater use for new drilling activities, particularly in critical groundwater areas.

Calculation of standing biomass is usually carried out using linear and non-linear regression equation models based on the type of plant or tree resulting from field measurements. The aim of this study was to estimate the estimation of biomass and carbon based on the slope of the secondary forest in the KHDTK educational forest of Mulawarman University. Mulawarman University Educational Forest. Data collection to calculate biomass and carbon stocks obtained by direct measurements in the field and utilizing the Geographic Information System. The results of the highest biomass estimation at the sapling level are on a slope of 25-45% with an average value of 12.599 tons/ha; at the pile level with a slope of 25-45% the average value is 28.412 tons/ha; at the tree level with a slope of 8-15% the average value is 155.024 tons/ha; and in a litter with a slope of 25-45% the average value is 38.12 tons/ha.

The city of Samarinda is one of the supporting cities for Indonesia's new capital city. This will of course have an impact on increasing infrastructure development in Samarinda. Land use scenario modeling is an effective alternative that can be used to understand land conditions by analyzing and simulating future land use scenarios. The aim of this research is to create a land use scenario model which can later be used as a spatial decision support system in policy making related to Samarinda city spatial planning and sustainable governance. The method used in this research is a combination of the Cellular Automata (CA)-Markov Chain model with Remote Sensing-GIS. The results of this research show that the Celelu Automata-Markov Chain based land use scenario model shows that in 2034 Samarinda City will experience an increase and decrease in area in several land uses. There has been a significant increase in the area of land use, namely settlements, mining, dry land farming mixed with bushes, and dry land farming. From CA-Markov modeling, changes in LULC will occur in the future. The detailed analysis in this research will be very useful as basic data information to help city planners and local governments for future planning and development as well as technical knowledge about landscape changes.

Environmentally friendly and sustainable palm oil management is one way that can be done in the face of competition for palm oil products produced. The Indonesian sustainable palm oil (ISPO) certification is the standard used in Indonesia, which needs effort and support from various parties. The purpose of this study was to formulate a strategy to strengthen the impact of ISPO implementation on KUD Bumi Subur Kertabumi Village Kuaro District Paser Regency. The research was conducted in July 2024. Data collection methods through surveys, and interviews with the help of questionnaires. In addition, focus group discussions were also conducted with smallholders and experts to formulate alternative strategies. The data analysis method used is the analytic hierarchy process (AHP) method for weighing alternative strategies to strengthen the impact of ISPO implementation. The results showed that alternative strategies for strengthening socio-economic impacts were based on the criteria of human resource management, with the alternative of smallholders understanding the standards of ISPO implementation. At the same time, strengthening environmental impacts on waste management criteria, namely distinguishing hazardous waste (B3) as an alternative strategy. Each alternative in the criteria is mutually supportive and related, but smallholders can determine the things that are prioritized to be done.

Coal mining activities have a significant impact on land degradation, including loss of topsoil, changes in soil physico-chemical properties, and decreased fertility. This study aims to analyze the soil chemical properties of post-mining land in Loa Janan sub-district, Kutai Kartanegara Regency, which will be used for revegetation activities. The research method used composite soil sampling at three depths of 0-10 cm, 10-20 cm, 20-30 cm on a 50 m × 50 m plot, then analyzed in the laboratory for pH, C-organic, N, P, K, and CEC parameters. The results showed that the soil was acidic at 4.80-4.91 due to pyrite oxidation, with very low C-organic content of 0.88-1.07%, N content of 0.09 - 0.11% very low-low criteria, P content of 0.01%, K content of 0.02-0.04% with very low criteria respectively. Soil CEC is also categorized as low at 14.67-16.38 me/100g due to the lack of organic matter. This condition is also affected by high rainfall which triggers nutrient leaching. This study recommends liming, adding organic matter, and balanced fertilization as rehabilitation strategies to improve soil fertility.
