CROOILSE: Eco-Crayon from Used Cooking Oil

Cooking oil is one of the goods that is often consumed by Indonesians, especially for household needs, such as cooking. The Central Statistics Agency and the Indonesian Palm Oil Entrepreneurs Association noted that demand for palm cooking oil, especially from households, tends to increase every year. The high level of cooking oil consumption results in more used cooking oil being produced. Used cooking oil can cause problems for the environment if not treated properly. Problems resulting from used cooking oil include damage to aquatic ecosystems, pollute the soil, and can clog waterways. Islamic boarding schools are one of the contributors to used cooking oil. This is due to the use of cooking oil which is high enough to supply the food needs of the many boarding school residents. In general, used cooking oil in Islamic boarding schools still cannot be processed properly. Based on these problems, the aim of this research is to make eco-crayons that use used cooking oil as an innovation for processing used cooking oil in Islamic boarding schools. Crayons are one of the equipment that are popular with students at the boarding school because using them can develop their creativity. The research results obtained are eco-crayons that have bright colours, are long lasting and easy to use. Thus, the presence of Crooilse can reduce used cooking oil waste and make it a useful tool for students.
