Abstract

Transportation as an activity of moving something from one place to another. The existence of various community activities causes the emergence of traffic movements. The more activities that take place, the more traffic generated. So that adequate infrastructure is needed to create a smooth movement. As the number of vehicles increases, the strength of the pavement decreases which results in road damage. Pavement in good condition in Samarinda City in 2020 decreased by around 6.3%, while roads in severely damaged conditions increased by almost 100% from 2015. Damage to pavement reduces the capacity of the previously planned roads. This affects the level of service on these roads, so it is necessary to compare the analysis of service levels with and without any damage. The research was conducted by surveying Ir. Sutami road, City of Samarinda with a length of 150 m. Primary data include the number of vehicles, road geometric data and documentation of road damage. The analytical method uses MKJI 1997. The volume of vehicles passing through Ir. Sutami as much as 1228.4 smp/hour on holidays and 3510.35 smp/hour on weekdays which are dominated by motorbikes. Road capacity Ir. Sutami in a condition without any damage, namely 6079.92 smp/hour which produces a V/C ratio of 0.58 with a service level of A, while currently the Ir. Sutami road with some damage such as holes and peeling so that the capacity decreased to 5251.067 smp/hour with a V/C ratio of 0.67.

Abstract

The purpose of this review study is to see the effectiveness of the method of implementing primary canals in the Semani environment (Sentosa-Remaja-Ahmad Yani) Management and Development of Drainage Systems that are Directly Connected to Rivers across Regency/City Areas and Provincial Strategic Areas. This condition shows the importance of handling drainage problems. Measurements use mechanical and manual, data collection is carried out in natural settings (natural conditions), primary data sources and data collection techniques involve more participant observation, in-depth interviews, and documentation. From the results of reviews and observations during practical work, I concluded that we can really learn the techniques and conditions for making good drainage. so that the desired results can be maximized. The benefit of this study review is that we know how effective the work of the Semani environmental drainage project (Sentosa-Remaja-Ahmad Yani) is. It is hoped that this will eliminate the problem of flooding in the area

Abstract

Bridge reinforcement with external prestressing method is a proven effective approach to overcome damage in strengthening bridge structures. This method uses the installation of prestressing cables outside the steel frame of the bridge to increase the strength and stability of the structure. The bridge structure is made with the guidelines of SNI 1725: 2016 standard steel frame of class A bridges, using IWF and H Beam steel, with a plate thickness of 20 mm with a span length of 60 meters, a width of 9.13 meters and a height of 6.3 meters. The structural analysis of this study uses the SAP2000 v22 software program. In this study, 3 prestressing cable tensions were compared on the reinforcement of the bridge frame with the external prestressing method. And a loading simulation was carried out which could provide a response in the form of strain due to moving loads and a bridge structure response that was reduced by approximately 50% from the deflection force on the steel frame reference bridge if given a moving load. Choosing a bridge that has the lowest settlement. The review point is determined for the comparison of deflection at point object 7 and joint object U3. The Type E cable-stayed bridge has the lowest results in percentage, about 46.68% for a speed of 40 km/h, 48.60% for a vehicle speed of 50 km/h and 49.91% for a vehicle speed of 60 km/h, indicating that this bridge has the best analysis performance among the cable-stayed bridges analyzed.
