Abstract

Kawasan industri di Kabupaten Gresik semakin berkembang pesat. Kebutuhan akan kendaraan angkutan barang juga semakin meningkat dan menimbulkan masalah-masalah rumit yang berkepanjangan karena masih sangat bergantung terhadap angkutan jalan. Oleh karena itu, perlu direncanakan kereta api logistik sebagai alternatif moda angkutan barang yang memiliki banyak keuntungan. Tujuan dari penelitian ini adalah untuk merencanakan jalan rel kereta api dalam hal geometrik serta RAB sebagai moda transportasi logistik di kawasan industri Gresik. Data primer diperoleh dari survei secara langsung. Sedangkan data sekunder yang digunakan berupa data jalur eksisting, peta topografi, spesifikasi kereta dan AHSP. Metode penelitian mengacu pada Peraturan Menteri Perhubungan No. 60 Tahun 2012 dan No. 78 Tahun 2014. Perencanaan menghasilkan jalan rel penggabungan eksisting dan baru dengan panjang total 19.159,837m serta memiliki 18 titik alinyemen horizontal SCS dan 55 titik alinyemen vertikal. Rencana anggaran biaya sebesar Rp. 155.916.827.800,00.

Abstract

Elevation measurement is essential for various applications, including construction engineering, monitoring land subsidence, maintaining infrastructure, etc. A conventional method for elevation measurement involves terrestrial surveying using a Total Station instrument. However, this method can be time-consuming and requires a considerable number of personnel. Unmanned Aerial Vehicle (UAV) photogrammetry method offers a more efficient solution for determining elevation. This method utilizes UAVs equipped with camera sensors to capture aerial photos. In this research, aerial photos were taken using three different camera angle configurations: nadir (90°), oblique (65°), and oblique (45°). The elevation points derived from the UAV photogrammetry data were compared with the elevation measured by the Total Station. The analysis showed that the nadir (90°) camera angle configuration had the lowest Root Mean Square Error (RMSE) at 0.0471 meters, followed by the oblique (65°) configuration with RMSE of 0.0508 meters, and the obliqu (45°) configuration with RMSE of 0.1399 meters. According to the t-test, the elevations derived using the UAV photogrammetry method were not significantly different from the elevations measured with the Total Station.
