Abstract

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%).

Abstract

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.

Abstract

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
