SUMMARY. Dwiyati, et al., in their paper, discusses the effect of gas flow rates of 1 L/min, 3 L/min, and 5 L/min on the hardness value of low carbon steel in the GTAW process. Basori, et al., in their paper, discusses designing a corn thresher machine with a 300 kg/hour production capacity. Adnan and Soegijono, in their paper, analyzed the intrinsic hysteresis curve of zinc oxide (ZnO) material. Kholil, et al., in their paper, analyzed the relationship between the diameter of the blade and ring on the chopping results on a plastic cup chopper so that the size of the blade and ring that can cut will be obtained. Syamsuir, in his paper, discusses the effect of tempering temperature and long tempering resistance on the hardness and wear resistance of HQ 760 steel. Nofendri, in his paper, discusses the addition of ethanol as a non-fossil fuel mixed with 5% and 10% RON 92 and RON 88 gasoline to determine the effect on fuel properties (research octane number, density, calorific value of fuel) and engine performance (power, torque, fuel consumption, and thermal efficiency). Syahril and Hidayat, in their paper, redesigned pneumatic equipment based on programmable logic control (PLC) for practical activities. Setyawan, et al., in their paper, designed a bicycle wheel with spokes made of wood.
