Abstract

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.

Abstract

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.

Abstract

Rompi tahan peluru sebagai perlindungan diri personel militer umumnya berbahan dasar komposit berpenguat serat sintetis. Komposit berpenguat serat kevlar dan karbon telah mampu menahan laju penetrasi peluru dan memiliki karakteristik ringan, namun biaya produksi dengan serat sintetis tersebut relatif mahal. Penggunaan material substitusi dari serat alam sangat potensial, dikarenakan jumlah serat alam yang berlimpah, ringan, dan harganya yang relatif murah. Salah satu serat alam yang potensial adalah serat dari pelepah salak. Penelitian ini berfokus pada pengaruh penambahan serat pelepah salak terhadap karakteristik komposit serat Kevlar dan serat karbon, dengan filler SiC dan Al2O3. Pembuatan komposit ini dilakukan dengan metode Vacuum Assisted Resin Transfer Molding (VARTM). Terdapat 4 variasi fraksi volume serat dan filler sebagai penguat yang ditambahkan pada komposit ini. Dari hasil pengamatan dengan SEM didapatkan hasil matriks dan penguat sudah terikat dengan baik. Hasil uji balistik menunjukan seluruh variasi sampel uji dapat menahan laju peluru sehingga tidak tembus. Hasil uji mekanik menunjukkan saat ini penambahan serat pelepah salak belum secara signifikan meningkatkan sifat mekanis komposit tersebut

Abstract

The development of computer technology has progressed very rapidly. CNC (Computer Numerical Control) machines have come a long way in the last few decades. CNC (Computer Numerical Control) machines were first introduced in the 1960s, and have undergone technological changes and improvements since then. A machine tool is very susceptible to inaccuracies resulting in a machine that is used for a long time and repeatedly can result in its feeding process. The deviating feeding process will greatly affect the quality of the workpiece. The purpose of this study was to determine the calibration process of CO2 CNC Laser Cutting Machines on the X and Y axes and the results for making machine feasibility decisions. The dial indicator tool will be used to determine the calibration results on a 2-axis CO2 Laser Cutting CNC machine for CO2 Laser Cutting. This CO2 CNC Laser Cutting Machine will be calibrated on each axis, namely the X and Y axes.

Abstract

The machining process of dry machining milling method is a machining process without additional coolant, but this method has several problems during the process and after the machining process, namely Tool temperature can easily rise and has a major impact on tool wear, so the purpose of this research is to develop a dry machining method with variations tools that are coated with nickel, by utilizing the properties of nickel material that can withstand heat and corrosion, therefore a nickel coating is used on the tool which will affect the temperature parameters of the tool. The coating method that will be carried out is the electroplating method. This method is a metal coating method which is often called electrodeposition, or the process of depositing the coating metal on the base metal using electrolysis. This research was carried out using experimental testing methods to obtain tool temperature parameters and hardness on the tool coating. The voltage used in the electroplating process is 6 V/ 0.7 A for 5, 10, and 15 minutes to produce a nickel layer thickness of 0.024 mm in 15 minutes, so every 5 minutes the layer is 0.08 mm. The experimental testing process used the HSS tool Ø 12 / 4 F and a aluminum 6061 workpiece which resulted in an intermediate temperature that was not coated with nickel (uncoated) at 3 mm feeding spindle speed 3000 rpm the temperature reached 73.6 ºC while that which was coated with nickel (coated) the temperature only reached 58.6 ºC, and get an average hardness value on the nickel layer, which is 279.9 Hv

Abstract

This study examines the scheduling of the Frame Acid Skid project at the Lombok Steam Power Plant (PLTU) using Gantt Chart and Critical Path Method (CPM). The primary objective is to identify the causes of delays and propose optimization measures for the project duration. Data collected indicates a significant difference between the planned duration (24 days) and the actual project completion time (47 days). The main delays occurred in the welding and painting phases, each requiring an additional 13 days. Contributing factors include the addition of a welding process for materials not covered in the initial contract and specification mismatches in the painting phase. Analysis with Gantt Chart and CPM reveals that enhanced communication, more detailed initial planning, and strict monitoring of project specifications are crucial to minimize the impact of delays on cost and time. The results of this study provide a strong basis for decision-making in similar future projects.
