Rancang Bangun Sistem Kendali Suhu Dan Kelembaban Udara Penetas Ayam Berbasis PLC (Programmable Logic Controller)

Abstract

Demand of chicken and egg is tend to increase. Big scale stock of chick supplied by medium scale ranch industry. The component of hatch midscale still imported. If the egg scale is big do not enable in manual. The objectives of this research are to make a control system of temperature, humidity and return the egg position used the PLC (Programmable Logic Controller), and test of performance the component and control system designing. Hens are as controller that have to conditioning of eggs at remaining humidity and temperature, analogue with this condition, this research is making the control system using RNTC as sensor of temperature and humidity. Plate containing water was defending humidity that placed below rack of egg which made of a perforated plate; while to return the egg position in rack used to a motor step. The results of this research are error temperature sensor is 0,98 percent, air temperature in room hatch to range from 35,9C 38 C and average air humidity is 66 percent, percentage of mistake of timer is 0,41percent, rack can return the egg position equal to half circle egg.

Keywords: control system, temperature, humidity, hatch, PLC.
