The current electrical dish machine machining (EDM) machine in the field of manufacturing has developed along with conventional machines such as Lathes, Milling Machines, and Grinding Machines as the leading technology. EDM is known for its ability to make complex shapes on very hard metals. EDM machines are widely used in the manufacture of dies, cutting tools, and molds that cannot be done with the cutting process. Therefore the level of electrode wear in the EDM process must be as efficient as possible. The research was conducted to determine the exact EDM process parameter setting values. Variable parameters are current, on time, off time. To optimize the response of this study using the Response Surface Methodology (RSM) method. High electrode wear is obtained in testing with parameters used Ton (300 ?s), Toff (15 ?s) and Current (20 A), and the smallest wear value is obtained in the test with the parameters used Ton (100 ?s), Toff (15 ?s) and Current (10 A).

One of the materials used in the building process is sand particle. Sand with uniform size is generally obtained from manual sifting processes that require a lot of human power and long sieving time, so a sand sieving machine is needed to minimize the use of human power and sieving time. The design is focused on sifting sand manually into sieving using a machine. The design of the machine uses design software to create a picture of the arrangement and working drawings of the components of the sand sieving machine. Based on the results of the trials that have been carried out, the machine can sift 5 kg of sand for 1.02 minutes and for 10 kg of sand can be sifted for 1.30 minutes.

EDM is one of the nonconventional machining processes when making workpieces with conventional machining processes is difficult. This process has been used effectively in machining hard, high-strength and high temperature materials such as high speed steel (HSS) materials. In this study, prototype of EDM machines was carried out with engine variables such as current (A), pulse on time (µs) and pulse off time (µs). The material used is high speed steel (HSS) material used in cutting tools such as turning tools and milling tools. Surface roughness and material removal rate are responses observed to determine the quality of material remaval. The quality characteristic of the surface roughness response is "smaller is better" and the quality characteristics of the material removal rate response is "larger is better. The purpose of this study is to determine the best process parameter level to achieve the required performance characteristics in the material removal process using prototype EDM machines using the gray relational analysis (GRA) method, three process parameters are selected such as current, pulse on time, and pulse off time. The taguchi 3 x 3 x 3 design is used as an experimental design.The best parameter level obtained is current 40 ampere, pulse on time 200 µs, pulse off time 20 µs.

The Heat treatment process is carried out to change the mechanical properties of a steel. Changes that are expected to produce new better mechanical properties so that they can be applied to a mechanical system. One of the benefits that can be obtained is the increase in the value of the hardness needed. The hardening process carried out on S45C medium carbon steel material containing carbon by 0.45%. The heating process is carried out using an electric oven. The heating process is carried out using an electric oven. The heating process begins with heating the steel at several different temperature levels then followed by a quenching process with several different cooling media. After the quenching process is carried out, the steel is tempered at a temperature of 500oC and measured hardness value using a hardness tester , measurements on the HRA. From several parameters of heat treatment carried out obtained optimal values at a heating temperature of 8500C with brine cooling media. The value of the hardness of the material obtained is 68 HRA. In addition to an increase in the hardness value of steel, there is also a change in the microstructure, the changes in the microstructure that occur are the higher the hardness value of steel, the more the amount of perlite.

Red brick is a very important building material in building construction. Red brick has a rectangular physical shape with a distinctive color, namely red. Red bricks are made of clay mixed with sand and water, then mixed evenly and molded as desired. According to the quality standards, red brick is said to be of good quality and quality if it has several criteria including having the required size, compressive strength, and water absorption capacity. This research was conducted to see the effect of the length of drying time after printing, the effect of heating time, heating temperature, and the surface topography of red brick. The data processing method uses the Response Surface (RSM) method using Design Expert 09 software. The results show the smallest compressive test value of 131.4 kg/cm2. The biggest value is 148 kg/cm2. The most significant influence on the red brick making process is the drying time. The longer the drying process will cause the water content in the red brick to decrease. The SEM results show that the effect of drying red bricks that experience longer drying will coalesce and crystallize more easily. Based on the analysis of the results of the study that a longer drying time will cause an increase in compressive strength.
