Hi Wahyu, sorry to see that you are running into this issue. Seems like something has gone wrong during the ThingWorx deployment because i see that the /Thingworx app is not started. Could you share with us some detail about your setup i.e. the tomcat version, ThingWorx version, persistence provider, etc.
May be also have look at the logs from the Tomcat. If ThingWorx 8.0 + version you'll need to be bit careful with the licensing (assuming you are doing paid ThingWorx installation)
