Abstract

In Indonesia, water resources management planning has done based on river area. But the problem is the calculation still based on population data with administrative boundary. This is caused by the lack of population data with watershed or river area boundary. Geographical Information System (GIS) is a tools to analyze, visualize and interpret data with spatial and geographic data. For this research, GIS is used to generate population data with watershed and river area boundary,then the result will used for domestic water demand calculation for Cisadane upstream watershed. For all district in Cisadane Upstream Watershed, the largest district in entire watershed are Cibungbulang, Leuwiliang and Nanggung. But the most dense population are Ciomas, Ciampea and Cibungbulang. The calculation using watershed boundary resulting significant difference from district boundary. With spatial data population using watershed boundary, domestic water demand calculation result can be more accurate than using all district population data.

Abstract

Bintang Alam is housing area in Karawang regency which often occurs flood. Bintang Alam housing has a land area of 147,33 ha and located on the edge of the Citarum River downstream section. Therefore, it is necessary to have a good implementation and planning for the drainage system in Bintang Alam housing. The research aimed to find an effective way to prevent and solve floods in Bintang Alam. There are 2 scenarios that applied to the drainage planning at the Bintang Alam estate. Scenario 1, direct runoff from housing area is going directly to channel then the outlet point and for scenario 2, most of the flow entered to the soil through the infiltration wells then some of its flow into retention ponds. With the application of the two ecodrains, it is proven that they are able to reduce the planned flood discharge in the area with infiltration wells to reduce flood discharge by 25,96% and retention ponds to reduce flood discharge by 33,91%.
