Abstract

The purpose of this multilevel shaft turning performance is to analyze the specimen used, namely medium carbon steel alloy and get good workpiece results, knowing the ductility of the workpiece by adjusting the tool blade, speed, time, depth of cut, and surface roughness. The research method used is the impact test method to see the results of the influence of strong currents in steel joints. The results of this study are cutting speed is very influential on the results of the surface roughness of the test material, can be seen from the data analysis and research results. The surface of the test material with the highest level of smoothness is obtained from the use of the lowest cutting speed (100 m/min) with a roughness level of (4.1). The highest roughness level (7.1) with the cutting speed used (200 m/min). The higher the cutting speed used, the greater the price of the surface roughness value obtained or produced. However, the wear of the tool blade used is likely to also affect the level of surface roughness. Geram income depends on the cutting speed, the greater the feeding motion used, the greater the thickness of the resulting geram. The smaller the cutting speed used, the smaller the resulting furrow.

Abstract

The banana gedebog waste chopper machine moves mechanically so that it cuts with a blade, the mechanical analysis of the machine consists of a chopper mechanism. For the analysis of choppers that use the main components, namely blades and shafts, while the driving mechanism is a supporting component such as electric motors, pulleys, and bearings. In analyzing the chopping machine aims to analyze the mechanical work of power and analyze the steps of each component work, analyze the results of the type of material usage of the blade. The driving engine power used is 94.57363 (watts) and the chopping force is 4.51375 x 10-6 (kg.m). The variation of rotation on the drive motor produces a variation of rotation on the chopping knife which has an average of good quality with the largest amount if using used blade material per car.

Abstract

Aliran fluida merupakan bagian ilmu mekanika fluida yang berperan penting dalam merancang sistem perpipaan. Perpipaan merupakan alat transportasi fluida yang banyak digunakan di industri. Fluida yang mengalir pada pipa akan mengalami kehilangan energi (head loss) yang diakibatkan adanya gesekan antara fluida dengan fluida dan fluida dengan pipa. Hilangnya energi pada fluida dalam sistem perpipaan dapat juga disebabkan karena lintasan pipa yang dilalui oleh fluida, seperti belokan pada pipa, penyempitan pada pipa (kontraksi) dan pembesaran pada pipa (ekspansi). Percobaan dilakukan dengan model perpipaan yang telah dirangkai. Hasil percobaan menunjukkan bahwa luas permukaan dari diameter pipa sebagai alat transportasi aliran bagi fluida sangat berpengaruh terhadap nilai head loss (Hf). hasil hitung Hf pada diameter pipa ½ in lebih besar dibandingkan pada pipa ¾ dan 1 inc sebesar. Sehingga semakin kecil luas penampang pipa semakin besar nilai head loss yang dihasilkan. Dengan daya dorong pompa sebesar serta bukaan valve penuh.
