Abstract

Pipe connecting system that is connected with a valve using a flange connection. This aims to make it easier to install or disconnect when needed. This connection system includes pipe connections to fittings, valves, equipment, or other parts which are separate parts of the piping system. The analysis of the flange strength on the 4 inch ball valve ANSI 300 aims to determine and ensure that the flange has strength and is safe at the time of tide due to the influence of the torque bolt. In addition, to ensure the connection does not leak when the fluid is passed. The main combination between internal, axial pressure and thermal loading needs to be considered. Flange strength analysis using Finite Element Analysis (FEA) method with use of Solid works software. The analysis of flange strength uses the method of "Flange as weakest part philosophy", namely the full rating used when the value of a certain pressure-temperature on ASME B16.5 is taken for the Maximum Allowable Working Pressure (MAWP) in the piping system. From the results of the FEA analysis, it was found that the flange on the 4 inch ANSI 300 ball valve meets the requirements according to MAWP at different temperatures and pressures. The value of the safety factor also shows that the flange is safe during the piping work process.

Abstract

Home industry for dynamo repair in Sindang Village, Sindang District, Indramayu Regency, in carrying out its business to repair electric motors, dynamos, and distribution transformers, is done manually using a mechanical counter. The damage that often occurs in this equipment occurs in the coil, usually caused by being overloaded so that it burns. Winding the coils/coils on the dynamo can be done manually or using a winding machine. The type of winding machine commonly used by the dynamo home industry in Sindang Village, Sindang District, Indramayu Regency, still uses a mechanical counter. The accuracy of the number of windings affects the result of the quality of the repairs, apart from the type of winding wire applied. The research method used is quantitative experimental research. So that the result is that the automation process of the dynamo roller machine has been successfully implemented; reading the results using a limit switch still needs to be applied at high rotation (above 1 rpm). This can be corrected by using another sensor (Photoelectric Optocoupler). In the calculation planning results from the semi-automatic dynamo winding machine, the moment of inertia is 49,092.6mm2, displacement is 200.1, loading is 4,924.8 kg.mm, and the most considerable stress is 10,050 N/m2. In contrast, the slightest stress is 0,087 N/m2.

Abstract

The infusion system is relatively simple and easy, namely by hanging the infusion bottle on a pole and utilizing gravity so that the infusion drops will flow through the hose and enter until they flow into the veins. In the world of medicine, the use of infusion systems can also be done to enter drugs. The use of this drug must be monitored to ensure the number of doses that have been entered is according to the doctor's prescription with an infusion system. This paper aims to design and manufacture an infusion drip controller with an Android-based telemetry system. The method of this paper begins with designing and using the VDI 2221 method. The main components designed in this paper are the open and closed components of the infusion drop rate. For manufacturing using 3D printing with PLA material. Meanwhile, the measurement results were tested using a measuring cup with a 5 mm scale with ± 0.02 mm of tolerance. The results of this design show that the open and closed tool components are elliptical with an axis in the middle. While the results of the test show a comparison between the required volume and the removal of the tool by 1.2%. The tool can also provide notifications to communication devices when the volume has been reached. So that the tool can be used by following the tolerance rules for infusion and drug intake.
