Train is one of the land transportation that is in great demand by Indonesians. In Indonesia, trains were first operated in 1867 but were only managed by PT. KAI Persero in 1945. In providing good transportation services, PT. KAI Persero has many supporting facilities. To maintain the quality of these infrastructure facilities, routine management and maintenance is required. One such infrastructure is a railroad. Based on data from the official website of PT. KAI Persero, the total length of railroads in Indonesia is 7,464 km. The railroad tracks are maintained and managed by a Road Inspector (PPJ). Until now, the Road Inspector (PPJ) in conducting the inspection has to walk approximately 16 km and still use manual tools. And damage that can occur to the rails, namely broken rails, rail joints, broken points, damaged bearings, collapsed rails, loose rail fasteners and spliced ​​joints and arches

Departing from this problem, Yogyakarta State University students who are members of the Student Creativity Program Karsa Cipta (PKM-KC) team consisting of Muhammad Adi Febri Setiawan (S1 Informatics Engineering Education), Rohmat Santoso (D3 Electronic Engineering), Ario Chandra Purpratama (Undergraduate Chemistry ) with supervisor Nuryake Fajaryati, S.Pd. T., M.Pd., Made an innovative railroad road inspector officer (PPJ) tool called the Autonomous Railways Monitoring Robot (ARMR).

"The Autonomous Railways Monitoring Robot (ARMR) consists of 4 parts, namely the main part in the form of a mini PC Rasberry Pi, the controller part uses an ardupilot controller device, the monitoring part is in the form of an ultrasonic sensor as a rail damage detector and a camera as a tool to see conditions on the railroad tracks. and the ARMR web for controller over the internet and streaming video. The Autonomous Railways Monitoring Robot (ARMR) is shaped like a remote car, but the tires are modified so that it can run on railroad tracks. " said Febri.

Febri added another feature of the Autonomous Railways Monitoring Robot (ARMR), which is that it can send the location of rail damage detected by sensors using GPS. The working method of this tool is also easy, namely ARMR walking along the train tracks according to the starting point of departure and the end point of the stop which is set via the web, then if the robot detects damage the robot will send the location coordinates on the web. Thus, road inspectors (PPJ) do not have to follow the railroad tracks, but only stay at the control station. This was revealed after winning the 2018 PIMUNY competition on July 18 2018 yesterday.
