Implementasi Inferensi Fuzzy Sugeno pada Sistem Otomatisasi Suhu dan Kelembaban Greenhouse

Abstract

The community food demand, especially vagetables, has increased every year. Some areas that were previously used as agricultural land, are currently being converted into residential land. In addition, climate change and crop failed have also caused a vegetable crisis. Greenhouse is a building construction with a transparent roof and light can penetrate it. So, environmental conditions inside can be manipulated, so that plants grow optimally. One of the media that can be used is hudroponic media. Pakcoy is one of the plants that can be cultivated through greenhouse, especially the Fuzzy Sugeno method. The main problems in this research are:1) How the differences of plant growth between pakcoy in the greenhouse with system and outside the greenhouse and 2) How does the application of the Fuzzy Sugeno method effect the temperature and humidity settings automatically? This research is a development research. The result of this study are: 1) Development of a prototype through the following steps: a) taking temperature and humidity using a DHT22 sensor; b) the stages of calculation using Fuzzy Sugeno are fuzzification, interence and defuzzification; c) Adjusting the fan speed; and d) Print the output data. 2) The calculation of the Fuzzy Sugeno method uses sample data in the form of a temperature of 30,20℃ (heat membership function) and 86.20% humidity (optional membership function) and the constant value (z7) a7 is 100 and the constant value (z8) a8 is 100 (rated fan speed). The results showed that the pakcoy in the greenhouse grew faster than the pakcoy that grown without a greenhouse.
