Abstract


Persimpangan lazim ditemui di daerah perkotaan. Tidak sedikit persimpangan menimbulkan permasalah seperti kemacetan akibat tundaan yang terjadi, salah satunya di Simpang Kentungan Kota Yogyakarta. Untuk mengurangi kemacetan dan mengurai volume kendaraan maka perlu dilakukan rencana pembangunan underpass di Simpang Kentungan. Penelitian ini berupa analisis kelayakan lalu lintas dan ekonomi pembangunan underpass Kentungan, Yogyakarta. Kelayakan lalu lintas dinilai dengan membandingkan kinerja jalan saat sebelum adanya underpass dengan setelah adanya underpass. Kelayakan Ekonomi dinilai berdasarkan analisis Benefit Cost Ratio (BCR) dan Net Present Value (NPV).Berdasarkan hasil perhitungan yang dilakukan, didapatkan Dj pada tahun 2020 (without project) yaitu 0,959 dari arah Timur dan 1,028 dari arah Barat. Derajat jenuh akan menurun pada jalan eksisting setelah beroperasinya underpass pada tahun 2020 dimana Dj menjadi 0,54 dari arah Timur dan 0,625 dari arah Barat. Berdasarkan hasil analisis kelayakan dari segi ekonomi akan didapatkan nilai Benefit Cost Ratio (BCR) = 2,112 > 1, Net Present Value (NPV) = Rp 348.867.160.752 > 0, Sesuai persyaratan untuk analisis kelayakan ekonomi, rencana pembangunan Underpass Kentungan Yogyakarta dikatakan layak.
