Reduced Rate

The reduction in green open space causes its reduction in the surface that can absorb water into the ground in residential areas. An increase in the amount of wasted rainwater that is wasted due to the reduced rate of water infiltration into the soil will cause flooding in the rainy season and drought in the dry season. A solution is needed to absorb water into the soil. Trisakti University in collaboration with Cisalak Village and the Indonesian Water Partnership held the training and counseling on the application of Biopore Infiltration Holes to residents of RW 12. This Community Service activity supports the program target of making 100,000 LRBs in Depok City. The method used was counseling conducted online and offline. After the counseling activity, the team made 80 LRBs equipped with booklets and X-banners containing procedures for making LRBs.

Soil Water Movement

Water conservation forests significantly contribute to the stability of mountain agricultural ecosystems in Hani Terrace. In this study, we analyzed the relationship between the stable isotopic composition of soil water and precipitation to determine the mechanisms of soil water movement in the small watershed of Quanfuzhuang. We observed significant seasonal variations in soil water sources: antecedent precipitation was the dominant supply during the dry season, and current precipitation dominated during the rainy season. The recharge ratio of precipitation to soil water in the grassland was significantly higher than that in the arbor land and shrubland. The influence of water infiltration, old and new soil water mixing, and soil evaporation on the soil water stable isotopes gradually decreased from the surface (0–20 cm) to the deep (60–80 cm) soil. We observed significant seasonal variability in average soil water δ18O in the upper 0–60 cm and lower variability at 60–100 cm. The average soil water δ18O was generally higher in the dry season than in the rainy season. The mixing of old and new water is a continuous and cumulative process that is impacted by soil structure, soil texture, and precipitation events. We therefore identified a significant time delay in soil water supply with increasing soil depth. Moreover, the piston flow of soil water co-occurred with preferential flow, and the latter was the dominant supply during the rainy season.
