Abstract

Plasma cutting is a method of cutting metal, especially steel, with relatively low cost and effectiveness, with satisfactory results. Where in the cut, it is enough to need a plasma cutting machine/inverter that is quite affordable, widely available in the market, and simple tools, an air compressor (no special oxygen/gas needed as in gas/oxygen and acetylene/LPG cutting), a power source, the material being cut and the cutting process can be carried out. How to use plasma cutting is relatively easy, namely by setting the machine and then directing the plasma torch to the cutting plane as needed by maintaining a stable movement and height. However, when we make repeated cuts, our concentration and physical strength will automatically decrease, so we need a tool that can help us direct/adjust the plasma torch, which is called a plasma cutting mechanism. After paying attention to these needs, a plasma cutting mechanism was designed with a working space/cutting length of 1200 mm, with a tool size of 1400 mm x 300mm x 200 mm length, width and height, estimated cost of Rp. 3,050,000,-, with a cutting speed setting of 100 mm/minute to 1000 mm/minute, a cutting height of 0 to 10 mm with an angle of 0 degree to 90 degree.

Abstract

Acceleration is the change in speed in a certain unit of time. The method applied in this research is the experimental method. The purpose of the analysis of the modification of the automatic clutch system to the manual clutch system on motorcycle acceleration is to determine the results of the modification of the automatic clutch system to the manual clutch system on acceleration. The results of the first test showed that the average acceleration in the automatic clutch system was 101.05 m/s2, and the second an average acceleration was 101.14 m/s2, so the average acceleration was 101.095 m/s2. When using the manual clutch system, the first test results obtained an average acceleration of 77.87 m/s2, the second obtained an average acceleration of 78.51, so the average acceleration was 78.19 m/s2. So the average acceleration using the automatic clutch system is 101,095 m/s2, while those using the manual clutch system are 78.19 m/s2. There was a very significant difference of 101.095 m/s2 - 78.19 m/s2 = 22,905 or 22.65%. This means the use of the manual clutch system accelerates faster than the automatic clutch system.

Abstract

This paper discusses the simulation of control of a clean water pump system based on PLC. This simulation tool uses 3 tanks: tower tank, consumption tank and ground tank. The PLC used is the Zelio SR3PACKBD Smart Relay. The input is a stainless steel rod sensor placed in the tower tank and ground tank. The output is 2 pump motors and a solenoid valve. PLC program used Ladder diagram with ZELIO SOFT 2 programs. The test results show satisfactory results and the equipment required is very simple compared to conventional controls.
