Female solo travel in Java, Indonesia?

I would definitely suggest: don't do it. if you require a safe trip, at least you must have a trustful partner or hiring guide whoever native indonesian or expat. if you have a lot of trip experiences to Indonesia, it will be okay. remember, Australia is different with Indonesia (urban & people condition). Java has the largest population, and the geographical condition is getting worse nowadays, it's always raining everyday. I'm myself Indonesian female 18 y.o living at Java, i dont have courage to have a solo trip crossing Java province. be careful & take care
