At this time the economic development and competence of rural communities are the focus of attention by all elements of society in Indonesia. One of them is by developing creativity and competence that is managing one plant that has future prospects both financially or in terms of benefits that are appropriate for the "Rosella Flower". Rosella flower (Hibiscus sabdariffa L.) is one of the natural ingredients that have benefits for disease prevention. Roselle calyx extract contains gossypetin flavonoids which can act as antioxidants. Roselle calyx has high phenol content. Today, consumers always want products that are practical, effective and efficient. Some processed products from rosella include tea, syrup, and jam. In the process of product diversification to be carried out, no dye is needed, because the roselle calyx has an attractive red color. The farmer group of Semen Subdistrict of Kediri Regency, East Java is a PKM partner in the business in the field of Post Harvest Management and Diversification of rosella flower products that are still within the scope of the home industry where the products produced are still in the form of dried flowers which are sold bulk with a natural drying system and are only sold in the form of dried flowers to collectors. Therefore, our thoughts arise to share knowledge and technology about post-harvest to the farmer groups Sri Cahyo Mulyo and Lestari Gondo Arum in the form of rosella cultivation, procurement of drying machines and how to use them, diversification of rosella flower products including syrup, jams, etc. as well as business prospect management marketing.
