Efforts to improve soil quality are relatively inexpensive, among others, through the use of natural organic material sources such as the return of waste or crop residues. So far, soil quality improvement is generally carried out by using various organic soil enhancers in the form of manure, compost, and plant biomass. In addition, currently biochar is known as an alternative in improving soil quality, especially when combined with organic fertilizers. This material is a material that is classified as a soil enhancer that can last a long time. Charcoal manufacture can use biomass waste, either from agricultural product processing industrial waste or wood industrial waste which is widely available in urban areas. As an agricultural country, a lot of waste materials are easily obtained and relatively cheap, especially agricultural wastes such as coconut shells, cocoa pods, rice husks, mangrove trunks, oil palm shells and others. These materials can be charred in a traditional way or with the use of simple technology to obtain biochar which is useful both for fuel and for improving soil quality. In the application of writing, an imperfect combustion process is needed, known as a torrefaction process or low pyrolysis. This process can produce charcoal containing activated carbon to be applied to the soil. The process of making charcoal can be easily carried out by the community by utilizing biomass waste to heat the material. In this Thematic KKN integrated PPM activity, an incomplete combustion model is developed to produce biomass charcoal and will be socialized and applied to the community. |
