The Indonesian supply is 220 volts at 50 cycles or Hertz. Multipoint adaptors (to connect the world's various plugs to the Indonesian socket which has 2 round plugs) are provided by most hotels if you phone Room Service or Housekeeping. Speak clearly and with an explanation when you ask for an adaptor or you'll get a doctor, as friends of ours once did.
Electrical adaptors that allow you to use your normal home appliances in overseas countries come in several different types.
Find out which one you need for any destination at www.korjo.com/cpa/htm/fs_secondary.asp?load=htm_adaptor_guide.asp&page_id=6 or www.voltagevalet.com/country/all.html.
These adaptors can also be purchased at the department stores in Bali for about Rp20,000 which is a bit over US$2. If you are a regular visitor to Indonesia it might be worth considering buying one of these and having it fitted to a power board of 4 outlets so that you have it available for more convenient multiple power outlets when you next visit.
If your home supply is 110 volts and your electrical equipment does not have a 110/220 or 110/240 switch you will need to get a voltage converter to step the Indonesian 220 volts down to 110 volts. These are best purchased in your home country as they are surprisingly difficult to find in Bali and if you do they are bulky and of unreliable quality.
