Analisis Dinamik Model Pengguna Barang Impor dan Lokal dengan Pengaruh Kebijakan dan Peran Media

The policy of importing goods has the possibility to become competitors of local products in the market. In general, people can choose to use local or imported products. Not infrequently people are more inclined to use imported products with consideration of brands and variations of choice. Of course, this competition has an impact on the absorption of local products by the community so that interventions need to be carried out to keep people from using local goods. In this paper, a determin-istic mathematical model is built to interpret the situation of users of imported and local goods by considering the number of imported and local products in the market and the influence of the role of the media in public education and persuasion efforts. Dynamical system theory is used to perform analysis on the model that has been built. The basic re-production ratio is determined to determine the absorption of imported products by the public. Then, numerical simulations are carried out to obtain predictions of the dynamics of users of imported and local goods by considering the implementation of the intervention.
