High population growth causes an increase in community mobility to meet their travel needs. This has an impact on the use of private vehicles that are not controlled, which is causing transportation problems. The solution to the transportation problem is to use public transportation as a mode of travel. The government is obliged to provide adequate public transportation so that people switch from using private vehicles to using public transport vehicles. In order to meet the needs of public transportation, therefore, the Surakarta City Government provides a free BST bus/feeder fleet specifically for student. In connection with this, a ticketing BST bus/feeder system is needed to monitor and supervise public transportation users. The aim of study is to develop a free ticket system for student to use public transportation in the form of BST bus/feeder using Android smartphone technology. By using this system, students are expected to depart and return from school using public transportation provided by the city government for free without the need to be escorted and picked up by parents or guardians. Study results is an android application called Ride for Free, which is user friendly and helps students to their daily riding activities to school.

高人口增长导致社区流动性增加，以满足他们的旅行需求。这对使用不受控制的私家车产生影响，从而导致交通问题。解决交通问题的方法是使用公共交通作为一种出行方式。政府有义务提供充足的公共交通，使人们从使用私家车转向使用公共交通工具。因此，为了满足公共交通的需要，泗水市政府专门为学生提供免费的 BST 巴士/支线车队。与此相关，需要一个售票 BST 巴士/支线系统来监控和监督公共交通用户。研究的目的是开发一个免费的票务系统，让学生使用 Android 智能手机技术以 BST 巴士/支线的形式使用公共交通工具。通过使用该系统，学生可以免费乘坐市政府提供的公共交通工具上下学，无需家长或监护人的护送和接送。Study results 是一款名为 Ride for Free 的安卓应用程序，它用户友好，可帮助学生进行日常骑马活动上学。
