System Dynamic Model for Lake’s Water Flow: A Case Of Situ Binong, Cikarang, West Java, Indonesia

Abstract

This study aims to develop a dynamic system model that describes the relationship of
water, socio-economic, and water resources (lake size) sub-systems in Situ Binong. In addition,
this study also aims to make predictions of water resources conditions (lake size) Situ Binong for
the next 5 years. The model is prepared using a dynamic system approach. The Situ Binong water
flow model is available water resources consisting of 3 sub-systems namely natural water flow
sub-systems, socio-economic, and water resources Situ Binong. The result of the research shows
that the requirement of Situ Binong water resources every year is increasing so that the volume of
Situ Binong is decreasing. In addition, the volume of water resources Situ Binong influenced by
supply and demand. Supply comes from domestic waste and natural water flow such as
precipitation, infiltration and surface flow. While demand comes from WTP intake, irrigation, and
evaporation.
