The head of state and inter-government in September 2015 agreed to set the world on a path towards sustainable development through the adoption of the 2030 agenda for sustainable development. This agenda includes 17 sustainable development goals, or SDGs, the which sets out quantitative objectives across the social, economic, and environmental dimensions of sustainable development all to achieved by 2030 (The United Nations 2015). The second goal has a series of targets to support the three interrelated components of the goal: ending hunger, achieving food security and improved nutrition, and promoting sustainable agriculture. Making the second goal is complicated as it couples natural processes with social and economic processes. Most targets concern the promotion of sustainable agriculture; this creates an imbalance and an additional objective proposed for nutrition. There is consensus on essential food security and nutrition indicators, but trade-offs with the environmentally focused goals make signs for sustainable agriculture more complex (Maryet al. 2015).
Indonesia is the third largest country in the world in producing a sweet potato. Sweet potato (Ipomoea batatas L) is cultivated as a perennial in tropical and subtropical lowland agro-ecologies, although it is well adapted to other zones and can grow over widely different environments (Agriculture, Forestry, and Fisheries 2011). According to the Food and Agriculture Organization (FAO) increase in productivity in 2020 to 0.61% of land area is 1.93% annually. Nutritional content of sweet potato is the most complete than vegetables (Anjak 2010). Sweet potato contains Vitamin A, Vitamin C, ascorbic acid, Tianjin, riboflavin, niacin, phosphorus, iron, and calcium. In addition to the content of vitamins and minerals, the levels of carotenoids in sweet potato as the main ingredient similar to the formation of vitamin A carotene in carrots (Nani & Yati 2013). In addition to nutritional completeness, some purple sweet potato contain anthocyanins which have a physiological function as cancer prevention, protection from bacterial, protection from liver damage, heart and stroke disease, as well as playing an important role in reflecting and repair of DNA, which can optimize the function of the body's cells (Rosidah 2010).
Sweet potato in Indonesia has potential as planned development of industrial raw materials, both for food and nonfood items. However, the sweet potato in Indonesia has not been regarded as an essential commodity and not optimal in its use. One of the areas that have the potential Semarang agricultural sector is quite large, and contribute significantly to efforts to achieve food security in the city of Semarang, which is in Gunungpati districts (Maria & Dicky 2012). The total area of 54.11 km , most of the territory consists of rice fields and plantations. Based on data from National Statistics Agency (BPS) Semarang in 2015, Gunungpati districts are the third-ranked as a most significant producer of sweet potato in Semarang, with a period of production by 23 ton (Dinas Pertanian Kota Semarang 2014).
The level of education and skills of the farmer in Gunungpati is limited or relatively more low so that they can not access to formal employment (Nurma & Iwan 2013). Residents mostly worked as a farmer; it is as much as 5.534 residents (BPS2015). However, processing of agricultural products from sweet potato untapped into high-value products or not used optimally. The sweet potato products are still minimal. Food self-sufficiency and food processing alternatives currently intensified by Semarang (Puji 2014).
Indonesian society is more interested in the beverage packaging, one of them is a soft drink, but it is most contain preservatives and sweeteners are not natural. Consumption of soft drinks plays a significant role in a variety of diseases like obesity, diabetes, dental and bone disorders, and others, more so among children and adolescents. The toxic effects of soft drinks have gained much attention, due to the frequent scientific reports and media attention (Xavier et al.2007). Therefore, empowerment by creating drink products innovation UMBIESS (Drink Sari Umbi) contains nutrients for a healthy body. The purpose of this program is to increase the sale of sweet potato, accelerating diversification with optimize the use of local food sources available, and can be exported to various countries, so that UMBIESS have high competitiveness in the international market. UMBIESS product is one of the community empowerment programs that create self-reliance efforts to alleviate poverty and strengthen food security of sweet potato, thus contributing to the Sustainable Development Goals (SDGs).
Community empowerment program UMBIESS production conducted in Gunungpati, Semarang. To facilitate the people in producing and marketing products UMBIESS formed the pioneer of SMEs, namely the Group of Women Farmers (GWF) "Karya Mandiri UMBIESS." Social entrepreneurship (ecopreneurship) is the field in which entrepreneurs tailor their activities to directly tied with the ultimate goal of creating social value (Samer 2012). A method used in this Community Empowerment Program is ecopreneurship method, namely by performing entrepreneurial UMBIESS production based on social issues would be the lack of innovation in the use of agricultural products sweet potato into a product that has a higher sale value. The steps committed in ecopreneurship method can be shown in the chart as follows:
Forum group discussion (FGD)
Through the activities of the Forum Group Discussion (FGD) conducted public education activities related to the potential goal sweet potato as raw material for the food industry viewed from resources; the flexibility of the article; the people acceptance; nutrient content; and business potential.
