Government policies in helping dairy farmers in an effort to meet the capital needs of breeding them is through a policy program Kredit Usaha Pembibitan Sapi (KUPS). KUPS is skim credit used to finance the development of cattle breeding and dairy cattle by businesses with subsidized interest rates. The problems that the distribution KUPS seen through the eyes of a banking institution is (a) the availability of information prospective potential borrowers are still minimal (b) the legality of ownership of assets (c) cattle breeding company still slightly. KUPS program has been rolled out since 2010, meaning that until 2014 the program has been running five (5) years. But the realization of its lending until September 2014, reached 15.42% of the amount of the ceiling of Rp 4.00 trillion. The realization can be said to be too small or fails. Of course there is the small achievements of the bank as an institution that is authorized to distribute funds would need to act professionally and carefully. Given the experience of lending a mass program past such cases KUT (Kredit Usaha Tani) end up with less encouraging. Instead the main purpose of the program is awakened, just the opposite of credit are understood as government social assistance by the debtor (the farmer). So it is very natural that the bank hand is always cautious. The study was conducted in West Sumatra in 2014, data analysis used data a simple cross-tabulation using the primary data and secondary data from interviews with respondents either breeders penmanfaat KUPS and banking institutions as channeling KUPS Keywords: Beef Cattle Development, Venture Capital, KUPS

The objective of this study to analyze the dominant factors that potentially could affect the food security of households in the village of Trimomukti, Candipuro District and the village of Kelawi, Bakauheni District, South Lampung Regency; look for the dominant factors that potentially could affect the nutritional status of children and how the relationship between household food security levels with nutritional status of children in the region. Results showed the average household energy adequacy in both villages is still highly dependent on food energy contribution of cereals, especially rice. Based on logistic regression model, Greater the number of members in a household with low income and food expenditure against revenue high, and obtained a principal food source rice from membeli or aid and subsidies as well as from the community Kelawi Village will have greater opportunities for prisoners vulnerable to lack of food.Based on ordinal logistic regression model, increasing age of a toddler with food consumption of energy sources that do not meet the need and the ratio of food expenditure of households on incomes greater, the chances these children will experience moderate malnutrition will be higher and even worse. Seen the relationship between household food security with nutrition status, if a food is resistant to household, the nutritional status of children under five will get better. Regional differences in factors that contribute to the adequacy of the village of rice per capita did not have a significant influence on household level food security and nutritional status of children. Keywords: food security, household, nutrition status
