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).
