Abstract

Currently, Indonesia has entered a new phase in the development of modern transportation infrastructure, namely high-speed trains initiated by PT Kereta Cepat Indonesia China. The design of the facility operated is an Electrical Multiple Unit (EMU) CR400AF that can drive up to speeds of 350 km / h. Of course, high train speed requires the reliability of railway road infrastructure, including the geometry and components of rail roads. The technical specifications of high-speed rail roads have been regulated in the Minister of Transportation Regulation Number 7 of 2022. The type of rail used by high-speed railway line components with a rail road width of 1435 mm is type R60 rail. However, the determination of the type of high-speed railway in Indonesia has not been completed by analyzing the strength of the rail structure in bearing the load working on it. Thus, this study discusses the influence of rail road geometry on the speed of facilities and evaluates the strength of Type R60 rail structures in receiving high-speed train loads. The analysis method uses the Beam on Elastic Foundation (BOEF) method which assumes the behavior of rails as continuous beams that receive loads on elastic foundation pedestals. The results of the study found that the value of the realized radius and minimum radius of the horizontal arch respectively amounted to 9,500 m and 8,502.94 m greater than the horizontal arch permit radius of 7,000 m, while for the value of the permit radius and vertical radius of the vertical arch of 25,000 m. So that the optimization of the horizontal curved radius to 8,502.94 m to be more in line with the ability of the path to serve passing facilities and is expected to be more effective and efficient in planning. The static load and dynamic load of the EMU wheel CR400AF of 81,662.50 N and 243,522.90 N. The maximum voltage and rail clearance voltage were obtained at 134.53 N/mm2 and 228.57 N/mm2. The strength of the rails is written in the form of a safety factor (SF) number. The calculation results show that the most critical SF value of the rail in receiving the load of high-speed trains is 1.70. Based on the results of BoEF calculations, R60 type rails have a high safety value in withstanding static loads and dynamic loads of high-speed trains.

Abstract

Transportation is one of the state's tools to drive the economy, the Jabodetabek community already has a fairly good means of transportation, one of which is the Transjakarta Bus. Transjakarta buses have also developed their routes and one of the routes that is quite busy is Puri Beta 2 - Latuharhari corridor L13E. Although Transjakarta Route L13E is operated by Express, there are still problems with the frequency of bus arrivals. This is because the L13E route does not fully have a dedicated path. There are still some segments mixed with other traffic. The purpose of this study is to determine and analyze the Transjakarta Bus Performance of Puri Beta 2 – Latuharhari L13E Route. The method used for this research is a survey method to the field to obtain research data. After the data is obtained, then an operational performance analysis will be carried out on performance indicators based on the standards of the Decree of the Director General of Land Transportation No.SK.687 / AJ.206 / DRJD / 2002. From the results of the study of seven operational performance indicators referring to the Decree of the Directorate General of Land Transportation No.687 / AJ.206 / DRJD / 2002 obtained five indicators with category A (Good), namely: 1) Headway (time between), 2) Load Factor (Load Factor), 3) Travel speed, 4) Service Time, 5) Waiting time. While there are 2 indicators with category B (Medium), namely: 1) Frequency, 2) Travel Time. Based on the overall assessment of the Operational Performance of the Directorate General of Land Transportation Decree No.687/AJ.206/DRJD/2002, Transjakarta Bus L13E obtained an A or Good grade. Based on the calculation of the maximum load factor, it is found that the bus stop that has the highest number of passengers or maximum load factor on weekday morning direction 1 towards Latuharhari is Adam Malik stop to Velbak stop, this also happens on weekend morning direction 1 towards Latuharhari, this is because Adam Malik bus stop is a bus stop that is quite busy with universities and densely populated areas and is also one of the stops of choice for the surrounding community to travel to the center city. In this study, it was also found that the maximum load factor on Weekday afternoon direction 2 towards Puri Beta 2 occurred at the Patra Kuningan stop to the Velbak stop, this is because the Patra Kuningan stop is an office area and also the Velbak stop is one of the choices for service users to be able to move to other modes of transportation.
