The potential of sweet potatoes in Dopang Village, West Lombok Regency is quite abundant, especially the type of purple sweet potato. In addition to its good health benefits, the existence of purple sweet potato also has high economic potential. Processing of purple sweet potatoes into more valuable products in Dopang Village is still considered lacking. Based on observations, the processing of purple sweet potatoes in the surrounding community is only in the form of snacks or chips. Therefore, this activity aims to develop processed products made from purple sweet potatoes into products in the form of sweet potato milk (Violatte) in the hope of increasing the economy of the local community. This activity is carried out in 4 (four) stages, namely; (1) product manufacturing experiment, (2) product improvement, (3) product socialization to the public, and (4) product marketing. The activity is carried out for approximately 1.5 months from November 22, 2021 - January 6, 2022. The location of the activity is in Dopang Tengah Hamlet, Dopang Village, Gunungsari, West Lombok, West Nusa Tenggara (NTB).
