Kambang Iwak (KI) RTH in Palembang is an oasis for the life of Palembang City. KI Park is always busy with residents visiting for recreation, on weekends KI Park is a place to unwind for local workers, and residents to exercise. The green route of the Muaro River in Padang City nowadays tends to be busy with city residents, especially in the afternoon before Maghrib, and several spots even have non-permanent stalls set up to facilitate residents' activities. These two green open spaces are mini objects in this research to see their recreational potential. This research aims to look at the recreational potential of residents in the Kambang Iwak RTH (Palembang, South Sumatra) and the Muaro River Green Route (Padang, West Sumatra). This research was carried out in two cities in two provinces, namely: 1) Kambang Iwak RTH, Palembang City, South Sumatra Province, and 2) Muaro River Green Belt, Padang City, West Sumatra Province. The data collected in this research was divided into 2 (two) groups, namely primary data and secondary data. The recreational potential in both green open spaces looks at the internal aspects of visitors which are obtained through questionnaires to visitors who are currently using the green open spaces. The research results showed that the highest user choice was the recreational potential of the Kambang Iwak Palembang green open space as a recreational destination for residents were enjoying culinary delights (93.47%), walking (91.84%), enjoying nature (89.39%), enjoying the air (88, 16%), chatting (85.71%), playing (75.92%), studying (66.94%), and cycling (59.59%), while the Sungai Muaro Padang RTH as a recreation destination for residents is to enjoy nature (84.52%), chatting (84.52%), enjoying the air (82.58), enjoying culinary delights (74.84%), traveling (74.19%), studying (74.19%), playing (67.74%), cycling (62.58%), and fishing (62.58%).

Utilization of natural biological resources and their ecosystems responsibly and sustainably can be achieved through environmental management efforts, such as conservation. One company undertaking such efforts is PT Pertamina Hulu Energi Ogan Komering (PHE OK), which manages a conservation area. This research involves observations in the conservation area to obtain current data (conditions and potential) and trends at the location, in order to formulate strategies for its protection and management. The study was conducted in the PHE OK conservation area in Peninjauan Village, Peninjauan District, Ogan Komering Ulu Regency, South Sumatra Province. Data and analysis were performed using vegetation analysis methods, resulting in several parameters, including Density (K), Relative Density (KR), Frequency (F), Relative Frequency (FR), Dominance (D), Relative Dominance (DR), Importance Value Index (INP), Dominance Index (ID), Margalef Species Richness Index (R), Shannon Diversity Index (H'), and Pielou Evenness Index (E). The analysis results show a positive trend, with an increase in biodiversity values from low in 2022 to moderate currently. Additionally, the R value for seedling level is moderate, while it is low for saplings, poles, and trees. The E value for seedlings, saplings, poles, and trees all fall into the high species richness category. There has been an increase in each biodiversity indicator value compared to 2022, indicating that the protection efforts thus far have produced positive outcomes. However, more extensive enrichment is needed to achieve a significant increase in biodiversity

Changes in land cover are thought to be the main factor in the Urban Heat Island (UHI) phenomenon. UHI is a form of local climate change which is characterized by an increase in temperature reaching 6oC in central urban areas compared to vegetated areas on the outskirts of the city. Compact vegetated land or Green Open Space (GOS), which is able to avoid increasing the surrounding temperature. GOR H. Agus Salim as one of the GOS in Padang City is a place for residents to have recreation and fill their free time by enjoying various culinary delights with friends and family as well as sports activities. This research aims to measure the benefits of tree canopies as climate amelioration in the H. Agus Salim GOR area. The research was conducted in September 2023, with 7 repetitions at 5 measurement points (3 under the tree canopy and 2 in the open field). Data is measured directly in the field with a thermohygrometer. The cooling effect provided by trees was analyzed using a difference approach between measurements in shade and open areas. Thermal comfort level is measured using the empirical formula Temperature Humidity Index (THI). The results showed that there was a decrease in temperature under the tree from 2,0oC (in the morning) to 2,9C (in the afternoon). However, THI calculations show that GOR H. Agus Salim is in the Uncomfortable criteria both under a canopy and in open areas.

Agroforestry is a land management approach that combines agricultural crops with woody plants to improve land production and community well-being. This study seeks to examine the typology of agroforestry and its contribution in promoting sustainable agriculture within the Community Forest (HKm) Kibuk, located in Pagar Alam City, South Sumatra. The research methodology employed is a mixed methods approach, incorporating both qualitative and quantitative techniques. Data were collected using field observations, interviews with 23 members of the forest farmer group, and an analysis of land cover alterations from 2016 to 2020. The research findings indicate the implementation of six agroforestry types in HKm Kibuk, predominantly featuring coffee trees (Arabica and Robusta) with protective species like as avocado and acacia, in addition to understorey crops like horticultural vegetables. Complex agroforestry systems incorporating diverse shade tree species possess greater potential for enhancing ecosystem resilience and augmenting carbon sequestration capabilities than simplistic agroforestry models. The primary problems encountered are the farmers' lack technical expertise and restricted market access. Consequently, it is essential to adopt measures that augment farmers' capabilities via training, legislative incentives, and the fortification of financing schemes to ensure the sustainability of implemented agroforestry systems.

Social forestry is a national priority program aimed at providing legal access to communities in managing forest areas to resolve tenure conflicts and improve community welfare. Since its implementation in 2016, evaluating its impact has become important, especially regarding land cover changes. This study aims to analyze the impact of social forestry approval on land cover in Makarti Jaya District, Banyuasin Regency. This research was conducted in December 2024 using the visual delineation method through on-screen digitization of Google Earth images from 2016, 2020, and 2024 at five locations that received social forestry approval in 2020. Data analysis was conducted using a geographic information system to observe changes in land cover area. The research results show that the approval of social forestry has a significant impact on land cover changes. The area of the forest has experienced a significant decline, especially in Forest Farmer Group (in Indonesia context called Kelompok Tani Hutan-KTH) Sungai Gulang, KTH Jaya Bersama, and KTH Semoga Jaya, which have been converted into coconut plantations. Meanwhile, KTH Usaha Makmur was able to maintain the forest stand, while KTH Sinar Tani completely converted its land into coconut plantations. These findings indicate that the implementation of social forestry needs to be balanced with stricter monitoring and guidance mechanisms to prevent wider forest degradation.

Uncertainty over forest area is one of the obstacles to effective forest governance in Indonesia. Of the total forest area of 130 million hectares, only about 12 percent (14.2 million hectares) has been demarcated. This uncertainty triggers tenurial conflicts with various parties with an interest in the forest area. The low income of the community triggers forest encroachment activities. Forest encroachment is a very effective alternative job according to the community to get a high income in a short time. As a result of the crisis, there was a conflict between the community around the concession area and PT Musi Hutan Persada (MHP). This research was conducted to find out and describe the pattern of land tenure by the community in the PT MHP permit area, analyze the form of partnership collaboration between communities, and find out the impacts and benefits of the collaboration scheme used. This research method is descriptive qualitative with data collection techniques of observation, interviews, documentation and literature. The triangulation technique was carried out by conducting in-depth interviews directly with selected informants. The results of this study show that based on the steatment area, the land controlled by the community can be divided into 2 land tenure patterns, namely land tenure patterns that have a steatment area of more than 50 ha with a total area of 47,568.64 ha and land tenure patterns that have a steatment area of less than 50 ha with a total area of 382.7 ha. Conflict resolution carried out by PT MHP on land that has a steatment area of more than 50 ha is managing forests with the community while land that has a steatment area of less than 50 ha is managing community forests. The impacts and benefits of the collaboration scheme carried out by PT MHP are the benefits for the company of establishing good relations between the company and the community, reducing fire levels, returning land that was once controlled by the community and not creating new conflicts.

Peat swamp forests in South Sumatra play a vital role in climate change mitigation through carbon storage and hydrological regulation. However, anthropogenic pressures such as illegal logging, land conversion, and recurring fires have led to severe ecosystem degradation, including within the Padang Sugihan Wildlife Reserve, which covers approximately 86,932 hectares. This reserve serves as a critical habitat for endemic flora and fauna but has experienced a decline in forest cover and ecological functions, ultimately affecting its carbon storage capacity. This study aimed to estimate vegetation density and carbon stock through a combination of field observations, spatial analysis (land cover change, NDVI, and carbon stock), and allometric approaches. Eight plots measuring 20×20 m were established based on the 2024 land cover map, representing similar secondary forest vegetation structures. The analysis followed SNI 7724:2011 standards for carbon stock measurement and calculation. The results revealed significant land cover changes between 2020 and 2024, including a reduction in secondary peat swamp forest and an increase in open areas, plantations, and water bodies. NDVI values and allometric measurements indicated spatial variations reflecting vegetation growth dynamics and carbon absorption potential. Plot 8 and Locus 4 recorded the highest carbon accumulation, at 1.602 and 10.63 tons CO₂e ha⁻¹, respectively, influenced by the dominance of Mahang species (Lauraceae family), vegetation density, and stand age. These findings highlight the critical role of secondary peat swamp forests in maintaining carbon balance and supporting peatland ecosystem restoration at the landscape level. The results also provide scientific evidence for developing sustainable management and conservation strategies for the Padang Sugihan Wildlife Reserve.
