The hydrogeological mapping of the southwestern part of Serang Regency, Banten, Indonesia

Abstract

The development of Serang City as the central government of Banten Province leads to persistently increasing demand for clean water in the area and its surroundings. This study aimed to perform the hydrogeological mapping of the southwestern part of Serang Regency. The study area covered four districts, namely Baros, Padarincang, Paburuan, and Ciomas. These four districts are the clean water source of Serang City that also functions as a buffer zone designed for the development of freshwater fishery and wetland agriculture. Hydrogeological mapping in the study area is expected to be one of the inputs in planning the use of water resources. The method used in this research included analyses of drill data, geophysical measurement results, the findings of previous studies, hydrological map scale 1:250000, and geological map scale 1:100000, as well as geomorphological mapping and field survey. This research produced six classes of hydrogeological units that covered areas with scarce groundwater productivity up to those with high groundwater productivity.

“…The media must be of good quality. This is regarding the visual development of both images and videos that must be in accordance with technical requirements [14].…”

Identification of degradation of groundwater recharge area infiltration quality on the slopes of Willis mountain

“…The increasing water needs are directly proportional to the increasing population, on the other hand the reduction of open land reduces the rate of infiltration of groundwater formation [1]. Groundwater is the main choice in the fulfillment of household water needs because of its relatively fixed availability and more naturally protected from pollution [2], in terms of the amount of groundwater is also more than other freshwater sources, so it can better support the lives of humans and other living things [3]. The increasing need for groundwater will affect water ecosystems in the groundwater supply area, as well as in groundwater release areas, so groundwater protection is needed [4].…”
