Help to Renovate a Non-Profit School in Indonesia

Sekolah Dahlia is a non-profit school that my parents own located in South Tangerang, Indonesia. This school starts from pre-school to grade 9th. At this school, we accept anyone who wants to study and let them pay with whatever they can (some pay $2 a month, some pay with a sack of rice, etc). We're having a financial trouble now that we cannot renovate the school classes that's currently not effective enough for the students to study at. We need your help, please.
