In 2018, both Riau and Kalimantan account for the highest number of forest fire incidences in Indonesia. This massively has impacts on society, environment, and economy. Arson done by big companies seems to be one of the contributing factors for the sake of economy. This research is aimed to analyse the state's responsibility for law enforcement over incidence of arson by companies due to economic reasons. Socio-legal research method is involved in this research with statute, conceptual, and case approach. The research result reveals that the government has at least issued 4 laws to give sanctions to any companies involved in the arson, involving the Law of Forestry, Plantation, Environmental Protection and Management, and Criminal Code. Moreover, the state is responsible for playing a main role in doing preventive and repressive actions towards the corporate that infringe the law, in which the preventive action involves forming the system responsible for control on forest fire which takes the participation of society. Repressive action, however, could be performed by sycnhronisation, harmonisation, and enforcement of laws and enquiries, forming a special court dealing with forest fire criminal act, and improvement of the regional government's and law enforcers' commitment. It is compulsory for the government to detain parties intentionally involved in forest arson.
