Abstract

Food is a main human need, fulfillment of food needs is be a basic component of national development. This research purposes are to analyze food availability for household level in West Lombok Regency, know access of dry land community to get food, to know adequacy of collected household food consumption at Lombok Barat.This research applied method deskriptive. Data collection used survey technique. Sample location determination by purposive sampling, 30 respondent are determined by accidental sampling. Data are secondary data from related agency and primary data from interviews with household respondents. The result shows West Lombok Regency is sufficent food. However, 60% of households in dry land do no have access to food, and 40% of them consume foods are categorised as insecure. Constraints for some community to achive food security are life habit, income, and low education.

Abstract

The flow of water beneath the earth's surface flows through the pores like rocks and other porous media that can be flooded by water. In the soil, water flows due to the difference in hydraulic height that is the difference from ground water level. Groundwater movement, generally moving water with relatively slow flow can be modeled using Darcy law and mass conservation laws. The model is approximated numerically using the Finite Difference Method with the ADI (Alternating Direct Implicit) scheme. The ADI method has an advantage in the accuracy or accuracy of the results and the speed of completion. The ADI method can be applied to two or three dimensional systems to obtain the tridiagonal coefficient matrix.
