Semi-Automatic Machine with Programmable Logic Controller in the Mendong Woven industrial

The focus of this paper is to propose a design of semi-automatic saving mendong (Fimbristylis umbellaris) weaving machines using a programmable logic controller (PLC). The background of this paper is that mendong weaving machines are tools used in producing mendong mats, but until now, the machines used are still manual. The proposed method is to design a machine using a PLC as the central controller by using six ultrasonic sensors and a DC motor to drive the lever to mendong weaving. This paper concludes that the total electrical power consumed by three systems is 42.38 watts without load, and 104.59 watts with a load. The most significant sequential electricity consumption is the pressing system, then the roll-up system and the lowest in the embroider system. Based on the results of testing separately, the components used are Mechanical devices, PLC, power supply, ultrasonics sensors, DC motor drive that works well. The overall test is a weaving time of 42.5 minutes with a length of webbing of 1 meter, spending 37.27 WH.
