Solo travel to Indonesia tips

Hi, I (23F) am planning on taking a solo trip to Indonesia in late August/early September. I would like to prioritize wildlife viewing and hiking. I live in the Marianas and am used to the perks of living on a tropical island so I am not prioritizing beaches. I would love any tips for what other people have loved and how to make solo travel as easy as possible. Also if anyone has any advice on whether it would be better to spend time in Sumatra or Borneo for wildlife viewing that would be really helpful. I am not sure if my plan is overly ambitious but it currently looks something like this: - fly into Jakarta - 3-5 days in Sumatra - 2-3 days in Bali - 2 days in Labuan Bajo - fly out of Denpasar

It’s not set in stone at all, but the main things I want to do is visit Komodo & see other wildlife in either Sumatra or Borneo. I am not looking to spend more than 15 days traveling. Thank you very much!
