Abstract

Polimer adalah salah satu material yang sering dikembangkan. Produk-produk dengan bahan dasar polimer khususnya plastik semakin diminati karena lebih efisien dan mempunyai sifat mampu bentuk (formability) serta sifatnya yang ringan dan tahan korosi. Plastik dapat digunakan sebagai pelindung suatu produk elektronik maupun benda-benda yang mudah retak atau pecah agar benda tidak rusak dan tetap aman. Airbag packaging adalah salah satu aplikasinya, oleh karena itu penelitian ini dilakukan untuk membuat serta menguji airbag untuk mengetahui energi yang dapat diserap oleh airbag tersebut. Pada penelitian kali ini dilakukan pengujian eksperimen dan simulasi. Penelitian dilakukan dengan mendesain airbag packaging agar penggunaannya dapat optimal. Bahan dasar yang digunakan untuk pembuatan spesimen menggunakan plastik polypropylene (PP) dengan variasi ketebalan 0,3mm, 0.5mm, dan 0,8mm untuk mengetahui energi yang dapat diserap oleh spesimen dilakukan pengujian tekan/kompresi dengan metode quasi static dimana pembebanan diberikan secara perlahan. Setelah pengujian eksperimen, dilakukan simulasi dengan bantuan software finite element dimana airbag diberi beban statis dengan input gaya perdetik dari hasil pengujian eksperimen. Berdasarkan hasil eksperimen di dapatkan data berupa energi (J) dan gaya (N) pada airbag dengan ketebalan 0,3mm energi yang mampu diserap sebesar 8,41378 J dengan F maksimal sebesar 205,262 N, ketebalan 0,5 mm energi yang diserap 11,4974 J dengan F maksimal 468,105 N dan 0,8 mm energi yang diserap 14,1742 J dengan F maksimal 569,242 N. Pada hasil simulasi energi yang di dapat untuk setiap ketebalan 0,3 mm, 0,5 mm dan 0,8 mm sebesar 8,3203 J, 11,778 J dan 14,41 J. Nilai tegangan ekuivalen maksimal dan deformasi total maksimal semakin meningkat untuk setiap ketebalan 0,3 mm, 0,5 mm dan 0,8 mm. Tegangan ekuivalen maksimal sebesar 37,501 Mpa, 38,854 Mpa dan 39,324 Mpa, sedangkan nilai deformasi total maksimal sebesar 9,6534 mm, 16,706 mm dan 18,793 mm. Polymer is one kind of materia that keeps evolving paroducys with polymers as their raw material are now gwtting more interest due to their higher efficiency, formability characteristics, also their light-weighted property and corrosion resistance. Plastics can be used for electronic good protectors as well as frail or fragile goods so they wont get broken easily and stay secured. Airbag packaging is one of the application of them, therefore this research is done for making and studying the airbag to find the energy which could be absorbed by that airbag. This research is done by experimental and simulation study. The research sets to design airbag packaging to get their optimal utilization. The raw material that used for making tthe specimens were polypropylene plastics (PP) with their variant of thickness are 0.3 mm, 0.5 mm and 0.8 mm. To get energy value that were absorbed by specimens, compression test were done with quasi static method where the loads are gradually given. After experimental study, simulation was done with a software finite element where a static load were given to the airbag with the input of force per second from the experimental study results. Based on the experiment, the data obtained were energy (J) and force (N) from the airbag with 0,3 mm thickness were 8.41378 J energy absorbed with maximum force of 205.262 N, from the airbag with 0.5 mm thickness werw 11.4974 J energy absorbed with maximum force of 468.105 N and from the airbag with 0.8 mm thickness were 14.742 J energy absorbed with maximum F of 569.242 N. Based on simulation result, the energy aobtained for thickness 0.3 mm, 0.5 mm and 0.8 mm were 8.3203 J, 11.778 J AND 14.41 J. The equivalent maximum stress and maximum total deformation are increasing for more thickness fromm 0.3 mm, 0.5 mm to 0.8 mm. The equivalent maximum stress were 37.501 Mpa, 38.854 Mpa and 39.324 Mpa, and the maximum total deformation were 9.6534 mm, 16.706 mm and 18.793 mm ( in consecutive with thickness above).
