Abstract

Urban areas have higher temperatures than rural areas. The existence of green open space (RTH) in cities is one of the efforts to reduce greenhouse gas emissions and increase greening in cities. This research aims to analyze the effect of vegetation on soil temperature and determine the effectiveness of vegetation in blocking radiation received on the soil surface at each depth. Soil temperature data was used at depths of 5 cm, 10 cm, 20 cm, 50 cm, 100 , and air temperature at the Banten Climatology Station from 2013 to 2023. Analysis of the average soil temperature at each depth of grass and bare soil at each hour of observation is presented in graphic form. Further analysis is carried out every three months, namely December-January-February (DJF), March-April-May (MAM), June-July-August (JJA), and September-October-November (SON) referring to the corresponding seasons with rainfall. The results of the analysis show that the annual average temperature of grass and bare soil close to the ground surface at a depth of 5 cm and 10 cm has a fluctuating pattern according to the air temperature. The grass soil temperature pattern is almost similar to the bare soil temperature, with the lowest to highest temperatures respectively at DJF, MAM, JJA, and SON. At DJF, MAM, and JJA at 07:30 WAS, the grass soil temperature was higher than the bare soil temperature with a difference of up to 1.1⁰C compared to the bare soil temperature, while at SON at 07:30 WAS, the grass soil temperature was slightly higher than the bare soil temperature up to 0.4 ⁰C and this difference decreases with depth. At DJF, MAM, and JJA at 13:30 and 17:30 WS, the bare soil temperature was higher than the grass soil temperature, especially at the surface and decreased with depth. At 13:30 SON and 17:30 WS, the bare soil temperature was higher than the soil temperature by up to 3.5⁰C at a depth of 5cm and the difference decreased with depth.
