Abstract

Palm oil mills in PT. Perkebunan Nusantara V PKS - Sei Galuh is a producer of crude palm oil CPO (Crude Palm Oil), which consists of several stations the processing of palm oil, one of which is the threshing station. Threshing station is the station there is a separation palm kernel process with the cluster in a way slammed into a rotating drum. The purpose of this research is to design the shape and dimension of the station threshing model palm oil mill in PT. Perkebunan Nusantara V - PKS Sei Galuh with scale of 1: 8 using Autodesk Autocad 2014 Software. Design of shapes and dimension threshing station model is divided into three groups, namely the design shape and dimension of auto feeder, design shape and dimension of thresher and design shape and dimension of screw conveyor. The design shape and dimension of auto feeder are 2 units sprocket and 11 plate shaped profile L. The design shape and dimension of thresher is a diameter of 230 mm and a length 500 mm. The design shapes and dimension of screw conveyor are 3 screw with a diameter of 100 mm and a length of each screw is 156 mm, 160 mm and 156 mm. Cover on the design of the shape and dimension of screw conveyor U-shaped profile with a diameter of 120 mm and a length of 620 mm cover.

Abstract

This paper presents a design for the automatic control system of the threshing station model using PLC Zelio smart relay. Threshing station is a station where a process of separation palm kernel from the bunch by way of slamming into a rotating drum. The threshing station model is a shape which resembles of the threshing station palm oil mill of PT. Perkebunan Nusantara V- PKS Sei Galuh, it has been scaled 1:8. PLC (Programmable Logic Controller) is a microprocessor based on instrument that can be programmed to control the machining process automatically. This system design has 2 inputs and 3 outputs. The inputs are push button to turn on and turn off of the works system and a rotary encoder sensor to detect rotating screw conveyor. The outputs are 3 units of DC motors. The programming language is used the ladder diagram by using the Software Zelio Soft 2. This system includes design of ladder diagram program, design of control system on auto feeder and design of rotary encoder sensor. The result of this design is revealed that auto feeder runs automatically turn on for 60 seconds and turn off for 30 seconds, continuously. The sensor works with voltage is 4.4 Volt at the moment un-stunted and 0.1 Volt when the stunted.
