Prototipe Pengukuran Potongan Panjang Kayu Pada Saw Mill Berbasis PLC

Sawmill is the process of processing wood that transforms logs into sawn timber, such as blocks and boards, ready for use in industry or construction. In the timber industry, the cutting process is carried out using several types of saws specifically designed to facilitate the cutting process. In addition, chainsaws also make work easier due to the limitations of human capabilities. In woodcutting factories, the presence of manual chainsaws becomes a limitation in cutting accuracy. This problem is because the cutting machine is still manual and has not been equipped with technology. With these limitations, research in the form of a prototype for measuring the length of wood cuts at a sawmill based on PLC was created. In this research, the system uses an incremental type rotary encoder and a 12-volt DC motor actuator. This system is based on a screw motor model to cut wood to a predetermined ideal length. Using HMI as an interface device makes the prototype more user-friendly and efficient. So that this research can achieve a cutting-edge accuracy level of 85%.
