The Implementation of Pyrolisis of Waste Material to Bio-Oil in the KKN Course

Kuliah Kerja Nyata (KKN) is one kind of university contribution to community. Through KKN, student also learn how to apply their knowledge and contribute it to community need. In Universitas Islam Indonesia (UII) there are two kind of KKN which are Reguler and Pembelajaran Pemberdayaan Masyarakat (PPM), which differentiate from the topic used.

Not all the sudent that include in unit 310-315, which come from different study, understand about pyrolisis. To settle this problem, experimental method was choose as learning method used, which help student understand about pyrolisis in limitation time. The effectiveness of this method was observed by observation, interview and questioner. The result show that expertimental method give good result. The student understand basic concept of pyrolisis process that needed in limitation time, eventhough they did not understand anything about pyrolisis method before
