Abstract
Smartphones are modern telecommunication devices that have become a way of life. However, smartphones have serious effects regarding possible harm caused by electromagnetic fields (EMF). The problem can be solved using Accumulative Roll Bonding (ARB) to have physical protection and reduce radiation emission. This research uses aluminum AA1100-O, copper ETP C11000, and pure lead L50042. This process was simulated using the Finite Element Method (FEM) using the ANSYS R2 2023 application to simulate ARB and then obtain strength values. ANSYS High Frequency Structure Simulator (HFSS) to simulate how far the plate is affected by smartphone radiation. This research uses plates with two sizes, namely 5 x 13 cm for three layers and 6 x 14 cm for four layers. The simulation research starts with the pre-treatment or heating process with the results of temperature and heat flux. Afterward, ARB processing was carried out for five cycles or five times. The result is that the pre-treatment simulation affects the results of the subsequent rolling process. The strength value of the material in the simulation also resulted in an average increase of 184%, with the highest increase in four-layer aluminum, at 375.2 MPa. In contrast to experiment research, where the highest increase occurred in three-layer copper, only 211.35 MPa. Finally, the research continued with radiation simulation and produced simulations that can absorb radiation with an average of 19%. Simulation research obtained the highest radiation absorber in four-layer aluminum, which is 216.3 μT, or % absorbance of 23%. In contrast to experiment research, where higher radiation absorber occurs in four-layer lead, which is 0.77 μT, or % absorbance of 97%, with an overall average radiation absorber material of 91%.

| Additional Information: | Smartphone merupakan alat telekomunikasi modern yang telah menjadi gaya hidup. Namun, smartphone memiliki efek serius mengenai kemungkinan bahaya yang disebabkan electromagnetic field (EMF). Masalah tersebut dapat dilakukan menggunakan Accumulative Roll Bonding (ARB) agar memiliki proteksi fisik dan mengurangi pancaran radiasi. Penelitian ini menggunakan material aluminium AA1100-O, tembaga ETP C11000, dan timbal murni L50042. Proses ini disimulasikan menggunakan Finite Element Method (FEM) menggunakan aplikasi ANSYS R2 2023 untuk melakukan simulasi ARB lalu mendapatkan nilai kekuatan. ANSYS High Frequency Structure Simulator (HFSS) untuk melakukan simulasi seberapa jauh pengaruh pelat dari pancaran radiasi smartphone. Penelitian ini menggunakan pelat dengan dua ukuran, yaitu 5 x 13 cm untuk tiga lapis dan 6 x 14 cm untuk empat lapis. Penelitian simulasi dimulai dengan proses pre treatment atau pemanasan dengan hasil temperatur dan heat flux. Setelah itu dilakukan pencanaian ARB sebanyak lima siklus atau lima kali. Hasilnya simulasi pre treatment mempengaruhi hasil proses pencanaian selanjutnya. Nilai kekuatan material pada simulasi juga menghasilkan kenaikan rata-rata sebesar 184%, dengan kenaikan tertinggi pada aluminium empat lapis, sebesar 375,2 MPa. Berbeda dengan penelitian langsung, di mana kenaikan tertinggi terjadi pada tembaga tiga lapis, hanya sebesar 211,35 MPa. Terakhir penelitian dilanjut simulasi radiasi dan menghasilkan simulasi yang dapat mengabsorb radiasi dengan rata-rata 19%. Penelitian simulasi didapatkan absorber radiasi tertinggi pada aluminium empat lapis, yaitu sebesar 216,3 μT, atau % absorbansi 23%. Berbeda dengan penelitian langsung, di mana absorber radiasi lebih tinggi terjadi pada timbal empat lapis, yaitu sebesar 0,77 μT, atau % absorbansi 97%, dengan rata-rata keseluruhan material absorber radiasi sebesar 91%. | |||||||||
