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.

The largest food commodity in Indonesia is rice (Oryza sativa), because rice is the main food source for most of Indonesia's population. Rice productivity can be increased, among others through innovation of high yield rice varieties, resistant to biotic and abiotic stress, and have good rice quality. The effort to form high yielding high yielding varieties requires several stages, one of which is power yield test. This research was conducted to obtain potential yield data from the four strains tested in the fourth generation. The strains studied were MS1, MS2, MS3 and ChM strains, with two varieties of varieties, namely Ciherang and Cilamaya varieties. This study used per-line planting method and conducted with Randomize Completly Block Design (RCBD). Observations were made on selected individual plants as samples. The variables observed were maximum plant height, maximum number of shoots, number of productive shoots, flowering age, harvest age, panicle length, number of grain per panicle, amount of unhulled grain per panicle, total grain per panicle, weight 1,000 grains, Clumps and grain yield per hectare. The data were analyzed by using variance, and if there was any difference between treatments, then the data will be tested further with Least Significant Different (LSD) on stage 5%.. Based on the observation and test, the result of production of each strain is MS1 strain of 7.24 ton.ha-1, MS2 strain of 6.06 ton.ha-1, MS3 strain of 6.29 ton.ha-1, and ChM strain of 6.01 ton.ha-1.
