PERENCANAAN GEOMETRIK PADA RUAS JALAN DESA JAHAB MENUJU DESA MARGAHAYU LOA KULU KECAMATAN LOA KULU

Abstract

The road is an important sector in the development of East Kalimantan province. ie, as a means of supporting the land transport sector, due to the way it can connect the region to region lainnya.oleh because it either in the planning or execution of the need to meet the requirements so that the path can provide optimal results for the wearer. Given the state of the country or geographical conditions 6 90% of the land area is hilly, especially in the Kutai regency Loa Kulu district so as to increase the traffic service and as an alternative way to simplify and speed up the flow in that region laulintas created this geometric design research. Getting results with the purpose of calculating the shape and magnitude of the Horizontal alignment Getting the shape and magnitude calculation Vertical alignment.

                        From the research results showed that most types of bends on rural roads towards the village Margahayu Jahab iyalah Spiral-Circle-Spiral (SCS), with one sample bend at STA 0 +075 with the values: V = 60 km / hour, D = 55o, R = 120 (R > Rmin), Ls = 70, U s = 16.710, p = 1.6961, k = 34.9013, x = 69.4078, y = 6.7627. While the visibility of view of stopping the STA. STA 0 +000 s / d STA 0 +200 = 88.83 m. and for Convex Vertical Elinyemen of STA 250 s / d STA 0 +350 0.068% with the height difference, Concave Vertical alignment of STA 0 +000 s / d STA 0 +250 3.822% with the height difference.
