I pay my live-in maid just under the minimum set for Sumatera Utara. However, on top of that she gets a weekly allowance for food and sundries. She used to live in 24/7 but I like to have the house to myself sometimes, so she goes home on Friday afternoon and has Saturdays and Sundays off. She also has very generous (paid) holidays for the same reason.
Her work definitely isn't onerous, and she does not have to 'work' 24 hours a day. In fact, as long as she gets through the work in a day, and meets the standards I want, it is up to her to organize how and when she does it. She likes to get her 'daily routine work' done early in the morning, then goes shopping, naps, visits a friend etc. during the middle of the day, and catches up on any special tasks later in the afternoon. She has usually finished everything by about 7pm but insists on waiting up until I arrive back from work at around 9.30pm.
Should I raise her salary to the minimum set? I will decide around Ramadan time, which is when I usually decide on pay rises etc. I have a handyman who comes in once a week to do routine (and non-routine) maintenance work. The same applies to him.
