Turning Waste into Blessings: Training on Processing Organic Waste as a Media for Cultivating Organic Mushrooms and Vegetables Abstract This service aims to train partners to utilize organic waste straw, sago dregs and sawdust as a growing medium for straw mushrooms. Next, the mushroom waste is processed as a vegetable growing medium. The main problem faced by partners is that they have not been able to utilize organic waste into materials that have economic value. The technique used in this community empowerment activity is PRA (Participatory Rural Appraisal) where the implementation involves the local community in all activities and local stakeholders. The advantage of this method is that it can improve the skills of partners because they are directly involved in the straw mushroom production process. The aim of using this technique is so that people can share and increase their knowledge about the conditions and life of the community, make plans and act. The success of the service process is assessed from the partner's competency in cultivating mushrooms and vegetables from straw mushroom waste. Partners have been able to cultivate straw mushrooms and vegetables as proven by the excellent mushroom harvest. Vegetables also grow well on mushroom waste media when compared to soil media. The temperature that is kept stable in micro barns has been proven to be able to increase production by 5 kg per shelf. If taken as a whole, there was a 10% increase in production compared to the size of the kumbung usually used by straw mushroom farmers. Based on the harvest results and trials of chili plants on straw mushroom waste, it can be concluded that the people of Bengkaung village have been able to use organic waste as a growing medium for straw mushrooms and are able to use mushroom waste as a medium for growing vegetables.
