Analysis of Bending Strength of Composite Materials in Bipolar Plates for Fuel Cell Technology
Full text linkThis study aims to this study was to examine the effect of polypropylene (PP) plastic and activated carbon (AC) composition in a plastic composite material. The composite material was mixed using an internal mixer at a processing temperature of 220°C and a speed of 50 rpm. The mixture was then molded with dimensions of 100 mm in length, 15 mm in width, and 2,5 mm in thickness. The sample molding was performed using a compression molding method with a pressure of 1500 MPa at 250°C and a holding time of 300 minutes. Subsequently, the samples were cut according to the bending test dimensions following ASTM D790-03 standards, with dimensions of 100 mm x 12.7 mm x 2.5 mm. The test results for the polypropylene-activated carbon composite in the first composition showed a maximum stress point of 36.95 MPa and an elastic modulus of 4.3096 MPa, while the second composition showed a maximum stress point of 34.58 MPa and an elastic modulus of 3.371 MPa. These findings indicate that increasing the activated carbon composition in polypropylene polymer results in a reduction in bending strength

Analisis Permukaan Baja ST 42 dalam Pengaruh Variasi Kecepatan Spindel dan Kedalaman Pemotongan pada Kekasaran Hasil Teknologi Pemesinan
Full text linkSurface roughness is an important aspect in machining that affects the appearance and function of the product. This study examines the effect of spindle speed and depth of cut on the surface roughness of ST 42 steel using HSS tools. Workpieces with a length of 300 mm and a diameter of 25 mm were processed with variations in spindle speed of 250, 350, and 450 rpm and depths of cut of 0.6, 0.7, and 0.8 mm. Roughness measurements were carried out using a surface tester. The results showed that at 250 rpm, the surface roughness was 0.0554 μm, at 350 rpm, 0.0517 μm, and at 450 rpm, 0.0416 μm. For the depth of cut, the roughness values were 0.0509 μm (0.6 mm), 0.0523 μm (0.7 mm), and 0.0542 μm (0.8 mm), respectively. The conclusion shows that increasing spindle speed reduces surface roughness, while depth of cut has a less significant effect
Monitoring Konsumsi Energi kWh 3 Phasa Secara Real Time Dengan Aplikasi Amicon
Full text linkPostpaid energy meter billing still often uses conventional methods in most areas of PT. PLN (Persero), involving personnel to manually read meters and collect data physically. This process includes visiting customers' homes to collect data, take photos, and deliver bills directly. The weaknesses of this method include potential inaccuracies in readings and the risk of data manipulation by personnel. To improve efficiency and accuracy, the Automatic Meter Reading (AMR) system has been introduced. AMR allows for remote reading and monitoring of energy consumption through communication media, reducing the need for direct interaction and minimizing errors and data manipulation. This system also facilitates the detection of electricity theft and energy losses, which can be caused by technical issues or illegal electricity use. Based on the results of the research carried out, there has been a voltage drop of 121.4 Volts or 51% of the nominal/transmit voltage caused by the kWh input terminal being damaged. The implementation of AMR technology in 3-phase kWh meters is expected to improve reading accuracy, reduce losses, and enhance customer satisfaction by providing real-time and automatic consumption data
