Forest is recognized playing a crucial role in Earth's life circle, specifically in terms the existence of human beings. As year goes by, the area of forest has been decreased significantly due to deforestation. Human beings claims that they need wider space area to live, build a house and run a factory or create a plantation to support businesses. They intentionally fires some forest areas without eco-sustainability consideration. In Indonesia, particularly, the cases of forest fires have been considered at critical level. To add, most of forest fires cases are done intentionally by the suspects. Those actions thus negatively impact a massive scope of ecosystem. Specifically speaking, it is not forest fires that brings drawbacks to the ecosystem, but the haze itself. The massive dark haze as a result of forest fires certainly pollutes the air which causes some breathing system-related diseases. Simply said, the disadvantages of forest fires have been violating human beings welfare (against humanity) and therefore be considered as a criminal action. Globally speaking, intentional forest fires have been ruled under criminal code in some countries such as Canada and Australia. Moreover, in attempt to overcome forest fires issues, Food and Agriculture Organization of the United Nations (FAO) provides a guideline for national legal drafters regulating forest fires law. Accordingly, those who are accused by criminal codes will be punished pursuant to criminal penalties regulated. In the States of Victoria (Australia), for example, criminal penalties of intentional forest fires (arson) have been effectively sentenced. From 2007-2012, 73 people were sentenced in custodial type by judges. On the contrary, although Indonesia has been regulated criminal penalties for intentional forest fires actors, they seem less powerful and effective in practice. Recently, on July 2016, Riau's forest fires case was intentionally dissolved by Indonesian National Police Officer. This fact thus raises an issue as to whether Indonesian Criminal Penalties for intentional forest fires actors have been effectively applied. This research aims to discover and solve the aforementioned issue. As a positive attempt, authors expects that this research will provide some recommendations to create more effective sentencing systems for the suspects. Authors will use sustainable forestry principles. In the end, Authors are expecting Indonesia will be able to overcome its forest fires cases effectively and more efficient.
