Design of Retention Pond Kacang Pedang Area as a Water Tourism Recreation Using Water Sensitive Urban Design

Abstract

Abstract The issue of changes in natural conditions, Pangkal Pinang City as a downstream area of the Baturusa Watershed (DAS) with a city center whose city morphology is a basin resulting in Pangkal Pinang City receiving excessive water runoff, plus land deforestation due to illegal mining in the upstream river which is directly adjacent to the Regency Central Bangka which causes excessive sedimentation and poorly connected drainage channels. The existence of high rainfall intensity and the uncontrolled capacity of the retention pond causes the water level to rise which then flows into the retention pond area. As a result, the Rangkui river causes excessive water runoff, resulting in floods that spread to residential areas and the center of Pangkal Pinang City. The purpose of this study was to provide design concepts for the retention pond area using the Water Sensitive Urban Design method as a strategy for urban water management, particularly in the region of raw water sources. The design process is a fragmented one that starts with a collection of regional design-related problems and ends with a simulation of regional design. Recreational, residential, and educational activities will all be accommodated within the design area’s 94 hectares. The design of the area will focus on urban design elements combined with normative principles, namely land use, intensity and building, circulation and parking, pedestrian ways, open spaces, signage, preservation, and activity support. In addition, the design simulation will also focus on the water management system in the area with a WSUD technical approach that is directed to focus on efforts to infiltrate rainwater and provide rainwater storage containers, both in open spaces, green areas, and buildings.
