Zero-Waste System Education in Ecotourism Area of Kebonagung Village, Imogiri District, Yogyakarta Province, Indonesia

The amount of organic and inorganic waste which has not been appropriately managed has become a global problem. The zero-waste system can then be a solution to waste problems. The zero-waste system must be implemented to protect areas with valuable natural and cultural resources. For instance, it could be implemented in the ecotourism area of Kebonagung village, Imogiri District, Yogyakarta. This educational program aims to provide understanding and upgrading skills related to the zero-waste system by creating a waste-free ecotourism area. This program will be conducted from December 2021 to September 2022 through socialization, waste treatment training and application, and evaluation monitoring. This program resulted in the socialization implementation of inorganic waste processing, liquid organic fertilizer, home-grown vegetables, Mina-padi (rice-fish farming), biogas, and Black Soldier Fly (maggot) larvae cultivation—which is the main focus of this program. Waste system training and application are carried out by turning plastic bottles into crafts, building Omah Maggot (a maggot breeding ground), also maggot cultivation training, monitoring, and guidance. This maggot cultivation could accommodate up to four kilograms of organic waste per day, along with a half kilogram of harvested maggot that could be harvested as fish seed. The remaining organic waste, known as kasgot, can be used as plant fertilizer. From evaluation to in-depth interviews, it is known that the community understands the zero-waste system concept and application. Yet, they lacked the organic waste handling experience for maggot, and no group yet can handle inorganic waste processing. From the results obtained, it can be concluded that this program received positive support and responses from the community that has gained knowledge and skills related to a zero-waste system toward creating a waste-free area.
