Abstract

One way to keep the train service flow runs safely, maintenance of railroad geometry is required. Maintenance of railroad tracks uses the Track Quality Index assessment to determine which railroad compartments or corridors are prioritized for repair. The research method used is a quantitative research method. The calculation of the TQI of railroad tracks includes force, height, spoor width and lining. The results of the calculation of the TQI value (manual) give the cumulative total number of standard deviation index is 21.6. While the TQI calculation (mechanical) total cumulative number index standard deviation is 21.2. Based on the results of the TQI calculation, the condition of the railroad tracks can be classified into the criteria for the TQI level II (standard deviation of 20 - 35), namely that the railroad can be passed by trains at speeds of 80-100 km/hour. The railroad maintenance based on the TQI is the repairs to rail compartments or corridors that experience leveling damage in segment 9, lining damage in segment 7, wide damage spoor (gauge) in segments 5,7 and 10 and elevation damage (cant) in segment 3.

Abstract

Salah satu daerah di kabupaten Banyumas setiap tahunnya ada yang mengalami permasalahan genangan dan banjir saat musim penghujan. Akibatnya genangan menyebabkan rusaknya jalan, terganggunya lalu lintas dan aktivitas masyarakat serta menyebabkan kerugian ekonomi bagi masyarakat di daerah genangan. Metode dalam penelitian ini adalah penelitian survey dengan metode deskriptif kuantitatif, dimana penelitian lebih mengarah pada pengungkapan suatu masalah atau keadaan sebenarnya dan mengungkapkan fakta-fakta yang ada. Pemilihan metode simulasi dengan menggunakan software SWMM 5.1. Berdasarkan hasil simulasi dengan software SWMM 5.1 dapat diketahui kapasitas air saluran drainase eksisting yaitu dengan Kala Ulang 10 Tahun terdiri dari 170 saluran, terdapat 85 saluran yang meluap dan 85 saluran tidak meluap, maka termasuk kategori kurang baik. Untuk menangani saluran yang meluap tersebut perlu dilakukan desain ulang untuk menambah kapasitas saluran. Dimensi saluran yang memadai adalah jika kapasitas air yang didapat kurang dari 1% sehingga saluran tidak meluap.

Abstract

. Based on the field observation at discharge measuring buildings, sometimes there are differences in the results of the distribution of discharge on land that is irrigated with the discharge channeled by officers. From this phenomenon, it is necessary to check whether there are any irregularities in the discharge measuring building. This research aims to calibrate the discharge measuring building in Kalibawang primary canal. The existing type of measuring building is a wide threshold measuring building. The principle of discharge measurement is to measure flow velocity, wet cross-sectional area, and depth. The measurement of the flow velocity in the channel using a calibrated current meter at various variations in door opening height. The current meter was chosen because it has good accuracy for measuring flow velocity. The data from this research was collected by dividing the channel width into several piece at various water depths, wet cross-sectional widths, and flow speeds. From the analysis results, there are differences between the theoretical discharge and the measured discharge. For example, the discharge formula coefficient for the first location is 1.67 b.h1.5, the formula correction is 1.78 b.h1.5. The positive or negative deviations from the comparison results between theoretical discharge and measurement discharge are caused by differences in the results of measurements on the current meter. The cause of this difference is damage to the body of the measuring building, such as cavities or holes and sedimentation
