Optimization of Sei Mangkei special economic zone (sez) industrial land based on user needs

Sei Mangkei Special Economic Zone (SEZ) is an industrial area with a total land area of 1,933.8 Ha, which is distributed into 18 (eighteen) zoning allotment areas. This industrial land zone has a 1 (one) type single plot, which is 1: 1 (200m x 200m) size or 4 hectares. With a single size pattern will result in high land residuals and cannot serve the needs of diverse users (markets) especially investors who need less than 4 (four) hectares of land. The pattern of size and variety of lots requires a redesign to be able to produce effective land use and provide optimal benefits for the company. In accordance with Permenperin No. 40 of 2016 that the pattern and size of industrial land is divided into 3 (three) sizes, i.e. plots of land ready to be built with small sizes ranging from 300 - 3,000 m 2 per lot, medium size 3,000 - 30,000 m2 per lot and large sizes above 3 Ha per lot. The method of optimizing the size and variety of lots uses a model of dynamic programming and linear programming with the help of POM-QM software.
