Radio was used exten- sively throughout the rural areas in the 1970s and early 1980s to promote the 'Green Revolution', which transformed Indonesia from a major rice importer to an exporter, and it was hoped that a similar miracle could be performed in the area of mother and child health.

Between legendary battles in the Snake Jungle involving the great fighter Nyai Sulih and the evil Ardo Walika and his henchman Sarpa, listeners hear two-minute spots featuring the jingle 'Let's go to the Posyandu", complete with information about 'one-stop' inte- grated health services. Radio Republik has been airing 16 similar advertising spots together with health talk shows and a 24-part series, Flowers of Life, on maternal and child care. The spots were developed in co-operation with the Centre for Health Education and UNICEF, which are currently working on a 52-part radio adaptation of Facts for Life.
