Abstract

Increasing and developing infrastructure in urban areas has resulted in decreased water infiltration quality into the ground. The increasing of settlement needs and raising its price has resulted in many water catchment areas changing their function unconsciously in urban areas. This condition was ultimately triggering the loss of opportunities for rainwater to into the ground. At present, when the rainy season arrives, almost all major cities in Indonesia experience flooding. The torrential rains that lasted just 1 hour were enough to cause relatively high inundation, which varied from 30 cm to over 1m. This study aims to analyze the intensity of rainfall and its impact on the potential for flooding in urban areas and how to overcome it by utilizing rooter system technology. The results showed that the 4-way rooter system technology's influence was considerable in reducing the water level. An experimental area of 100 m2 treated with a rooter system of 16 pipes with a water level of 40 cm can infiltrate stagnant water into the soil within 120 minutes. Meanwhile, in the same area without rooter technology, it takes 400 minutes to absorb water into the soil until the stagnant water is completely gone. This proves that the rooter system technology plays a significant role in accelerating water absorption into the ground, reducing the risk of flooding.

Abstract

The forest is seen as an ecosystem, because forest is formed or composed by many components, each component can not stand on its own, can not be separated, even interplay and interdependence. One component forests have an important role to the availability of nutrient cycling in the forest is humus. Humus is part of the composition of the forest has its own function in maintaining the balance of nature. Without humus, then the forest will lose its function in maintaining the stability of the hydrological cycle and soil nutrient cycling. Accordingly, this research aims to detect differences in the thickness of humus at a distance of  0-500 m of agricultural land society, to determine the distance to the forest by forest communities Dolat Rayat villages, districts of Karo, and determine the impact of forest humus decision on vegetation For seedling and saplings. This research showed that the availability (thickness) humus in Forest Park (TAHURA) bordering agricultural land within the community is varied from 0-500 m and impaired. Withdrawal of forest humus reaches a distance of 250 m, and humus began to stabilize in thickness at a distance of  350 m into the forest. Withdrawal of humus also affects the amount and type of vegetation growing in the forest so that species diversity of an area to be low. In areas that do not damage the forest and humus disturbance to the number of individuals, and higher species diversity. Keywords: Forest Humus, Vegetation, Nutrient Cycle, Agricultural Land, Society
