ABSTRACT – The process of edge detection on aluminum 1100 material as a result of welding tungstent inert gas (TIG) has been successfully developed, difficulties in the edge detection process due to the large number of impurities in the form of vertical streaks on the weld metal can be overcome using several methods. Of the many methods used, double thresholding and hysterisis have the most important role and contribution in the process of cleaning impurities. The hough transform process requires setting the number of meeting lines to get two lines with rho = (229, 146) and theta = (1.582496, 1.553343). Method 4 is the shortest method of pre-processing until line detection, namely GS > Gauss > Sobel > DT > Hys > HT. In further development, the development of an interface that makes it easy to vary the threshold value and the number of meeting lines, then the pixel/mm or pixel/cm scale calibration process needs to be carried out.

Analysis of Shape and Number of Blades on Portable Cooling Chip Fan for Metal Drilling Process with Flow Simulation

2023-06-19T09:24:28+00:00

In the metal drilling process, tool temperature is an important parameter for optimizing cutting conditions, by limiting tool wear so that surface roughness can increase. The temperature rise that occurs in the metal drilling process is related to the rate, drill speed, and drill diameter, the drill speed which has a significant influence. One of the efforts to reduce the temperature of the drilling process is by using the Minimum Quantitative Lubricant (MQL) method. The MQL method is more effective by utilizing the surrounding air by making a fan that produces cold air. The method of this research is Computational Fluids Dynamic (CFD) simulation using flow simulation, with parameters 3 shapes of the blades, and variations in the number of blades 3,5 and 7. The purpose of this study is to analyze the shape and number of blades on a portable chip fan for metal drilling cooling processes. The CFD simulation results obtained from Model 2 and the number of blades 3 with a minimum temperature of 29.87°C and a maximum temperature of 30.19°C.

Perbandingan Variasi Power Dalam Proses Laser Engraving Terhadap Hasil Produk Stainless Steel

2023-06-13T06:04:19+00:00

Marking machining processes using lasers have developed in the industrial world. Having high precision and good final quality is one of the advantages of this laser machine. There is a thermal effect generated in the process, so we must understand the impact of the power applied to the material. Carry out the laser marking process with the engraving method on a stainless steel plate material which is given a variation of strength to observe the difference in the final result of a marking. Make as many as 3 pcs of products for each variation of power parameters. The product that has been produced will also be observed for surface roughness on the marking, which aims to find out how deep the food is from the marking. Observation of the surface roughness of the marking on the product using the Surface Roughness Tester 3 times for each product. The results of the data that have been taken will only be observed and entered into the marking results into the roughness class according to ISO or DIN 4763:1981. The marking process uses power variations of 20%, 40%, 60%, 80% and 100%. The results of the marking with the lowest power of 20% produce markings with a roughness value of 0.029µm – 0.110µm and enter into class N3 while the results of marking with the greatest power of 100% obtain a roughness value of 18.210µm – 19.876µm which is included in the roughness class N10. Based on the data obtained in the engraving process with different power variations, it can be interpreted that the higher the power supplied, the higher the roughness value

CV. Dea Ayu Lestari is a company that operates as a collector and seller of solid waste from factory production. In this company, a small part of the PPIC system is being tested to gain an overview of how the system would work in a large manufacturing company. The data processing process is already computerized but still limited. Some of the newly available data processing processes include processing stock information, which includes incoming and outgoing goods data, as well as stock reports.The system development method used is the Waterfall method, and the development tool utilizes Unified Modeling Language (UML) modeling. This system is created using PHP version 5.4.7 and the database utilizes MySQL version 5.5.27. The result is an information management system for processing company data that allows administrators to quickly, accurately, and computerize the data recapitulation process. It covers stock data, incoming and outgoing goods, employee attendance, payroll, financial reports, and sales reports. Likewise, the company director can easily access information in the form of reports such as stock reports, incoming and outgoing goods reports, employee attendance reports, payroll reports, financial reports, and sales reports for the company they manage.
