Abstract. Abstract. Gracillaria verrucosa seaweed is usually used as a raw material for making agar-agar, but it is necessary to develop alternative products that have economic value and good nutritional value, one of which is processed dodol. Dusun Tlocor, Kedungpandan, Jabon is mostly in the form of aquaculture and Gracilaria verrucose seaweed producers, as well as marine tourism destinations. Tlocor has great potential for the development of seaweed-based products as well as a typical snack center to support these tourist destinations. The problem faced is that the potential has not been optimally developed, related to the need for a dough molen machine for seaweed dodol production. Community service activities were carried out first by providing training on how to make seaweed dodol that has a good taste and good nutritional content. The second stage was to demonstrate the making of seaweed dodol as well as provide assistance for the dough-making machine to the Dusun Tlocor community group that cultivates seaweed. The third stage was to assist with the registration of a seaweed dodol product name permit, a business group for the seaweed farming community, and the marketing strategy for the product.  As a result of the socialization and training carried out, the community received very good improvements in terms of skills in making dodol, knowledge of dodol ingredients, and skills in using the dodol dough mixing machine. Abstrak.
