Abstract

The main objective of this study is to analyze the unit cost of day old chicks of  layer and the break event point of small eggs farm. The data was taken from the survey conducted in 1990 and 1993 in West Java. The data was collected through indepth study in the poultry breeding farms and the egg  production farms. The result showed that the unit cost of day old chicks is Rp 617 per chick where as the actual price is much higher i.e. p 1350 per chicks. This information showed that the small farmer have paid high marketing cost. The research has also shown that the break even level of eggs farm is mainly depend on feeding price and egg price. The ratio of egg price to feed price at the break event point 2,57.

Abstract

The first consideration of multisolution is laid on an idea that economics is a science subjected to a set of decision alternatives. Existing math models utilized, however, are generally static in nature reflected by only one solution as a result and there are no other alternatives provided. The unique solution gives no possibilities to develop economic decisions. Therefore, a multisolution calculation based on existing economic math models is required to be engineered. The main objective of this paper is to perform optimum multisolution of a Linear Programming Model. The conclusion of this paper show that the multisolution analysis on solution of LP's optimum condition finds several important issues. One of these conclusions shows that the LP's optimum solution is not always economically efficient. Besides the alternative owns similar objectives only different in how resource is allocated so that in the optimum alternatives there are possibility to insert the reality problem of resource into the decision making process.
