The chain emerged from a small roadside stall at
Bendungan Hilir opened in January 1972 by Bustaman, a migrant to Jakarta from
Tanah Datar Regency. By 1975, Bustaman had managed to open a second location in Roxy,
West Jakarta, but named the location there "Singgalang Jaya" (after
Mount Singgalang) instead of Sederhana. Between 1975 and 1984, Bustaman opened a further five Singgalang Jaya branches across Jakarta. In 1978, however, after the Roxy branch was closed due to new property development, a new branch was opened in Rawamangun, East Jakarta, under the Sederhana brand. Bustaman operated ten branches by 1995. The Rawamangun branch is today the chain's flagship location. The first Sederhana location outside of Jakarta was in
Surabaya, opened in 1996. From this branch in Surabaya, the first franchise investor (a second branch in Surabaya) was found in 1998, and the brand began to open locations outside of Java through franchising. The company supplied spice mixes to its branches from a central kitchen in
Ciledug. ==Operations==
