Sistem Pakar Penentuan Kesesuaian Lahan Berdasarkan Faktor Penghambat Terbesar (Maximum Limitation Factor) Untuk Tanaman Pangan

Knowledge about suitability of the land and the plants can minimalize harvest plant problem. The spread of information technology and digital era also change the ways to explain and distribute information and knowledge used for recognize land suitability, with the creation of expert system. Process to recognize land suitability in this system using 19 parameter included physical and chemistry characteristics, and also nature factors such as temperature and rain fall. For all of these parameters, there are 2 complementary parameters to replace data about tekstur, drainase, and slope. Object in this research are 14 kinds of food plants. This system using Fuzzy Inference Systems (FIS) method for processing data. User can choose trapesium or Gauss function for fuzzificy the data. Based on actual values of the land, this system will determine the suitability of the land for food plants and for specific kinds of food plants. This system also determines about limitation factors for the land and gives some managerial suggestion for handling those factors. The results of this system also included about plants grow requirement and suitability location on 2 districts at East Java Province
