June 1990, Kristiadi was installed as the Chairman of the State Administrative Agency (LAN, Lembaga Administrasi Negara), replacing Bintoro Tjokroamidjojo who became the ambassador to the Netherlands. Under his leadership, LAN began implementing changes on Indonesia's civil service education system as well as the agency's institute. The central government then issued a decree in 1994 which enforces the role of LAN in Indonesia's civil service education system. In response to this decree, LAN began establishing cooperation with national and international establishments, such as the British Council and the Hasanuddin University.
