The main idea of the article is stressing social reintegration as the philosophy of Indonesian corrections (Pemasyarakatan). As a philosophy, Pemasyarakatan first established in 1963-1964 period. The idea of social reintegration in Pemasyarakatan, which is influenced by Bentham and Mills utilitarianism, is not fully mean as a theory for offender treatment in prisons. In practice, the idea of community based correction is compatible with social reintegration. In order to renew the correctional law, some clause in correctional administration are important.
