It was relatively easy to guess this sign advertised the services of a hairdresser. First there was the pair of scissors and "rambut" reminded me of "rambutan", the delicious fruit with a hairy skin. Once back home I could check in the dictionary and found that "potong rambut" means "haircut". "Hairdresser" would have been "penata rambut".
The second line of the sign tells the opening time. "Buka" means "open" and "siang" refers to the part of the day that corresponds to the late morning and early afternoon, roughly between 11:30am and 3:00pm (in Indonesia, the day is divided between "pagi", "siang", "sore", "malam", and "tidur").
Open 11:30am - 3:00pm
