ABSTRACT
The term Green Water has often been heard in various circles of human life. Green water is rainwater that falls and has been absorbed by the soil or plants. While the term is also very closely related to the term Blue Water which means water from rivers, lakes and groundwater. The attachment of Green Water and Blue Water is related to the old paradigm of water management which only considers blue water (river discharge, lakes and groundwater) while the new paradigm actually includes Green Water as an important component. Green Water is a form of water saving that will not interfere with water bodies on this earth. Green Water can also be utilized by areas experiencing drought, such as Majalengka Regency which in 2017 experienced drought in 27 villages according to the Regional Disaster Management Agency. One of the uses of green water is to build rainwater reservoirs or also known as reservoirs. Embung functions as a water conservation building in the form of a pond to accommodate rainwater and runoff water as well as other water sources to support agriculture, plantations and livestock, especially during the dry season. This study aims to identify areas that have the potential to build rainwater catchment areas or reservoirs. In addition, this study also compares the existing reservoir with the potential of the area or the suitability of this study. Identification of potential areas is prioritized in drought-prone areas according to the Regional Disaster Management Agency and according to hydrogeological conditions. In addition, the determination of potential areas also uses 4 physical variables, namely soil use, soil texture, rainfall and slope. Through the overlay technique, the four physical variables are combined in Majalengka Regency and given a score after which the flow accumulation method is carried out to see the accumulation of flow from Majalengka Regency in order to determine potential location points or suitability. After that, the potential area or suitability that has been made will be compared with the reservoir that has been built. So it can be seen that the area that has the potential to build a reservoir is the northern region of Majalengka Regency which is indicated to be a drought-prone area and is a potential area according to the suitability of the region.
