Abstract

The industrial world and vehicles that currently exist make the pollution level increase. Often we see thick smoke rising out of the factory chimney, the thick smoke is a waste of gas released by the environmental factory. The scrubber system is a collection of various air pollution control devices that can be used for particles and / or gases from industrial output gas streams. The term scrubber is also used to describe a system that injects or enters a dry active ingredient or liquid into a dirty gas stream to clean acid gas. The design of the venturi scrubber aims to design a venturi scrubber to reduce soot emissions on direct injection diesel engines, get a standard venturi scrubber design and reduce soot levels. This design begins with determining the alternative design, determining the venturi dimensions and the material that will be used to build the venturi scrubber.

Abstract

the use of dictionaries is not only used manually by searching for words in the dictionary book but also digitally which facilitates the work in searching for the meaning of the word. Due to the number of dictionary applications at this time it is done in the development of dictionary applications supported speech to text features in the search he said. Making this application using SQLite database and editor of Android Studio. The use of this dictionary not only functions in searching for the meaning of words, but there is also a list of tensis that comes with text to speech. This application can make it easier to find words and know about tensis. The end result of this application has been tested with several smarthphone with different android version and the result of this application can run well. The drawback of this application is the use of speech to text features that are still online, and data that can be entered into SQLite can not be much and limited, text to speech can not explain tensis accurately.

Abstract

Electroplating is one of the engineering improvements in the characteristics of metal materials. Copper coating is a pre-coating before further coating for steel. The surface area of the material is in line with the strong current requirements required for the normal coating process. However, too much current flowing into the cathode results in erosion at the anode. Silicon Controlled Rectifier (SCR) is a component made of semiconductor silicon. It has a function as a controller or switch. Silicon Controlled Rectifiers can be used to reduce coating currents in copper electroplating. The setting of the coating current can be done on copper electroplating of low carbon steel cathodes with a cross-sectional area of 7500 mm2 of 4.5 A; 5 A; 6 A; 6.5 A and 6.7 A. The best copper coating results with a 10 minute coating time are shown in the current 6.5 A with a coating mass of 1.11 grams and 1.06 grams. This proves the need for a reduction in the maximum flow so that optimal coating is achieved.

Abstract

The basic principle of metal formation is a process that is done by giving shape changes on the workpiece. This shape change can be done by providing an outer force resulting in plastic deformation. The application of this metal formation can be seen in some examples such as rolling, bending, forging, extruding, wire drawing, deep drawing, and so on. In the process of formation of this metal is also used tooling (bending) whose function gives style to the workpiece, and direct the change of shape. Knowing the speed of the power forwarding system on the pipe roller machine starting from the power source until power is used as the work cycle, and to know the type of belt, the length of the belt used on the pipe roll machine. From this research can be concluded that: (1) In bending the thickness of 4 mm pipe the required power is 582.4 N with power of 0.4 hp then the motor required 1 hp, the diameter of the pulley used is 2 inch for motoran and 8 inch for the pivot reducer, belt used type B with length 44 inch, (2) To reach the rotation of ± 2 rpm ie pulley diameter used with the ratio of pulley ratio is 1: 4, the reducer is used with the value I = 60 and sprocket ratio 1: 3.
