A System Dynamics Model for Developing an Agropolitan Area based on Laying Hens in Lima Puluh Kota Regency

Abstract

The development of an agropolitan area based on laying hens in Lima Puluh Kota Regency faces many problems. One method that can be used to solve these complex problems is the systems approach. This study aimed to build a model for developing a sustainable agropolitan area based on integrated laying hens farming. The results of the system performance indicated that the current system is in a fairly sustainable position. The dynamics of time will make changes in system performance in the future. There are six factors that influence the interdependent system, namely carrying capacity, egg prices, farmer income, employment, infrastructure, and utilization of livestock waste. Based on the state of each factor, three scenarios were formulated for the development of a sustainable laying hens farming system in Lima Puluh Kota Regency: (1) conservative-pessimistic scenario, (2) moderate-optimistic scenario, and (3) progressive-optimistic scenario.
