Just moved to Indonesia

Hi,,
I just moved to Indonesia and I want to ask what kind of activities can I join, preferable if it is in the region of Jawa Barat?  I already speak some bahasa and I been to the country before but it was almost four years ago. If anyone knows please let me know.
Greatful for answers,
Kind Regards
