Health risks
Health risks include malaria (especially malaria tropica, the most dangerous), dengue fever, giardiasis, hepatitis, Japanese encephalitis. Vaccinations definitely seem like a good idea, especially for hepatitis and typhoid fever. Also bring your malaria tablets! Although in the highlands the risk of running into malaria mosquitoes is very slim, in the hot and humid lowlands of Indonesia you definitely are at risk. If you have symptoms (fever attacks) don't wait, but go see a doctor. Even if you use malaria tablets, you can still catch the disease, because more and more mosquitoes are resistant to the medicine.
Also rabies is still present in Indonesia. Especially pay attention when you are feeding monkeys.

Food
All water can be a potential health risk. Don't drink it, use it to brush your teeth or put it in your drink as ice if you are unsure it wasn't boiled first.
