Office hours start from 8am to 4pm, or 9am to 5pm. Lunch break occurs between 12 noon to 1pm. Usually offices are closed on Saturdays, including government offices. Government office hours start at 8am and end at 4pm.
Standard banking hours are from 8am to 3pm from Monday to Friday. However, several banks open their branches in hotels (and shopping malls) longer than office hours and a few are open on Saturdays, so you might want to check first. Jakarta has a number of international banks, even though you can also exchange currencies in some hotel cashiers and official money changers.
The Indonesia Rupiah is also called IDR. Information of daily exchange rates can be found in newspapers or from the net. Some Indonesia banks provide this on their websites. IDR and US$ are the most acceptable currencies. Most tourism resorts have money changer facilities. When you are travelling to remote areas it is advisable to exchange your money and clear your cheque. Credit cards are only accepted in big hotels, restaurants, shops and travel agencies.
Electric power supply is 220 volts in all regions. So be careful with your 110-volt electronic equipment. The sockets will only fit with two pin, rounded-tip plugs (technically known as Type C, E, and F) otherwise use adaptors. Most hotels and many restaurants in large cities provide internet connections or free WiFi.
