Abstract

Indonesia is a country with geographical conditions located in tropical rain climates, causing variations in rainfall levels. High and varied rainfall can lead to surface run-off and soil erosion. This study aims to determine (1) the rate of surface run-off and soil mass erosion in acacia (Acacia mangium/A. mangium) stand, sengon (Falcataria moluccana/F. moluccana) stand, and open land; (2) the status of erosion hazard index, erosion hazard class, and erosion hazard levels occurring in A. mangium stand, sengon stand, and open land; (3) the relationship between rainfall and surface run-off and soil mass erosion. Erosion Measurement Plots (EMP) measuring 4 m × 10 m were established in the study site, consisting of three plots namely EMP A. mangium, EMP sengon, and EMP open land with steep slopes (25-45%). The total measured surface runoff (SR) during the study period at EMP A. mangium was 335.37 m³/ha/year, EMP sengon was 950.77 m³/ha/year, and EMP open land was 2,646.95 m³/ha/year. Meanwhile, Eroded Soil Mass (ESM) during the study period at EMP A. mangium was 0.85 tons/ha/year, EMP sengon was 2.39 tons/ha/year, and EMP open land was 195.45 tons/ha/year. The Erosion Hazard Index (EHI) value at EMP A. mangium and EMP sengon was classified as low, while at EMP open land was classified as very high. The Erosion Hazard Class (EHC) in EMP A. mangium and EMP sengon belongs to EHC I (very low), while in EMP open land belongs to EHC IV (high). Erosion Hazard Level (EHL) at EMP A. mangium and EMP sengon was included in the currently class, while at EMP open land was included in the very heavy class. The information about surface runoff and soil erosion on different land covers can be used as considerations in soil management, especially for post-mining lands.

Abstract

Bukit Pelangi is one of the areas that has urban green open spaces in Sangatta City. Venus Park, which is located in the Bukit Pelangi area, has many functions, including absorbing carbon dioxide (CO₂), producing oxygen (O₂), lowering the environmental temperature, and providing a cool atmosphere, making it a choice place to relax.This study aims to determine the microclimate conditions and the level of comfort in three different land cover types (Venus Park, built-up areas, and open land) as well as to understand visitor perceptions of the comfort and available facilities in Venus Park, Sangatta City. Data collection was conducted using an environment meter for 30 days, measuring indicators such as light intensity, air temperature, air humidity, and visitor perceptions through questionnaires. The results showed that the average light intensity in Venus Park was 897.2 lux, in built-up areas 1,690.5 lux, and in open land 2,006.9 lux. The average air temperature in Venus Park was 28.1°C, in built-up areas 29.3°C, and in open land 29.9°C. The average air humidity in Venus Park was 81.1%, in built-up areas 76.2%, and in open land 75.2%. The comfort index (Temperature Humidity Index) for Venus Park (27.3), built-up areas (27.9), and open land (28.4) are included in the comfortable category. Based on visitor perceptions, the level of comfort in Venus Park was categorized as good. The information about comfort index and visitor perception can be used as a reference in planning the development of green open spaces, such as city parks, urban forests, and other open areas.
