ANALISA PENGGUNAAN SILICON CONTROLLED RECTIFIER PADA ELEKTROPLATING TEMBAGA/BAJA KARBON RENDAH

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

Monitoring of Rice Dryer Machine Using Tray Dryer Method

Indonesia is an agricultural country with 40% of the population's livelihood provided by farmers. Harvested rice typically has a moisture content of 20-27% on a wet basis. The type of artificial dryer that is often used is the tub or rotary type. This research aims to develop a rice dryer using a combined tray and rotary-type method. Based on the result, the higher the speed dryer, the shorter the drying time. The net result of this test is that the relationship between time and engine speed is inversely proportional. The higher the speed, the shorter the drying time. The net result of this test is that the relationship between time and engine speed is inversely proportional. Rice drying results can be described as dry, but not including ready-to-eat rice standards. The higher the speed, the shorter the drying time

Studi Kelaikan Tower BTS Berdasarkan Sudut Kemiringan, Kekencangan Baut, Kekuatan Beton Serta Pengukuran Ground

Telecommunication Network Tower is a tower made of a series of iron profiles or rectangular or rectangular pipes, or rectangular long pipes intended to accommodate antennas and radio transmitters and receivers of telecommunications and information waves. In principle, BTS towers have the function of connecting network user communication devices to other networks. To support the smooth operation of the network, the building will remain solid and secure for a certain period. Investigation of the feasibility condition of the tower structure is very important to determine the overall condition of the tower structure. The methods used are hammer test, check bolt tightness (torque), measure slope (vertical), grounding, and visual observation. From the results of the test data obtained the average bolt tightness is 432.86 Nm. The tower slope test of 1.90 cm on leg A smaller than 3.6 cm is considered good because it is still within the tolerance limit of the bat slope, the average soil resistance measure smaller than1 ohm used is very good, and the visual physical conditions are very similar, so it can be done Tower in safe and working conditio
