REDESIGN GEOMETRIK JALAN PADA RUAS JALAN RAYA SALOPA DESA KAWITAN KABUPATEN TASIKMALAYA (STA 0+000 - 0+750)

Abstrak

Road geometry is the planning of the physical form of a road, taking into account technical,
economic, and environmental aspects to ensure the safety and comfort of users. Kawitan Village
Road, Kecamatan Salopa, faces various problems, such as damaged road conditions, steep slopes,
curves, and the absence of shoulders and road markings, all of which have the potential to cause
accidents. Redesign is a solution to these geometric problems, aiming to improve and enhance the
road's condition. This study aims to redesign the geometric road and determine the horizontal and
vertical alignment on the Salopa highway section of Kawitan Village, Tasikmalaya Regency, by using
quantitative research to obtain primary data and Tata Cara Perencanaan Geometrik Jalan Antar
Kota Tahun 1997 and the 2011 AASTHO reference for secondary data. The benefits of this study can
provide technical solutions for improving road geometric conditions, as well as being a reference
for practitioners in road geometric design. The results of the study show that the Salopa highway
section of Kawitan Village, Tasikmalaya Regency has a design speed of 40 km/hour, a road length
of 514.81 m, a road function Kolektor III B, a road type of 2/2 – TT. The horizontal alignment
produces 3 SCS type curves with each angle and radius of 67.93˚ and 241 m, 110.191˚ and 99 m and
31.472˚ and 178 m. While the vertical alignment produces 3 convex curves with LV design values of
50 m, 25 m and 102 m and 3 concave curves with LV design values of 8 m, 32 m and 45 m.
