Abstract
Penambahan filler pada silicone rubber telah banyak diteliti untuk mengamati pengaruh penambahan filler terhadap karakteristik dari silicone rubber, salah satunya adalah nanoselulosa dan barium heksaferrit. Nanoselulosa memiliki struktur kristalin, dan barium heksaferrit memiliki kekerasan, kemampuan menyerap gelombang radar, serta sifat tahan api yang baik. Tujuan dari penelitian ini adalah menganalisa pengaruh penambahan filler nanoselulosa dan barium heksaferrit terhadap morfologi, densitas dan kekerasan komposit silicone rubber / nanoselulosa / barium heksaferrit serta kemampuan tahan api silicone rubber. Variabel yang digunakan pada penelitian ini adalah matriks silicone rubber dengan fraksi massa filler nanoselulosa sebesar 0% dan 6%, serta fraksi massa barium heksaferrit sebesar 0% dan 20%. Pengujian yang dilakukan dalam penelitian ini meliputi Pengujian Porositas, Pengujian XRD, Pengujian FTIR Pengujian Densitas, Pengujian Flame Retardant, Dan Pengujian Kekerasan. Berdasarkan hasil pengujian porositas, diketahui bahwa penambahan filler nanoselulosa dan barium heksaferrit memberikan pengaruh pada porositas komposit, yang menyebabkan porositas terdeformasi, dengan area porositas terendah dimiliki variasi 6% nanoselulosa + 20% barium heksaferrit sebesar 19,083%. Dari pengujian densitas, diketahui bahwa penambahan nanoselulosa dan barium heksaferrit meningkatkan nilai densitas, dengan nilai densitas tertinggi dimiliki variasi 6% nanoselulosa + 20% barium heksaferrit sebesar 1,202 g/cm3 . Penambahan nanoselulosa dan barium heksaferrit juga meningkatkan nilai kekerasan, dengan nilai kekerasan tertinggi dimiliki variasi 6% nanoselulosa + 20% barium heksaferrit sebesar 67,986 Shore A. Nilai rata-rata laju pembakaran dari silicone rubber sebesar 0,291 mm/detik, dengan pembakaran tidak habis.

The addition of fillers to silicone rubber has been widely studied to observe the effect of adding fillers to the characteristics of silicone rubber, one of which is nanocellulose and barium hexaferrite. Nanocellulose has a crystalline structure, and barium hexaferrite has hardness, ability to absorb radar waves, and good refractory properties. The purpose of this study was to analyze the effect of adding nanocellulose and barium hexaferrite fillers to the morphology, density, and hardness of silicone rubber / nanocellulose / barium hexaferrite composites also flame retardancy of silicone rubber. The variables used in this study were silicone rubber matrix with nanocellulose filler mass fractions of 0% and 6%, and barium hexaferrite mass fractions of 0% and 20%. The tests carried out in this study include Porosity Testing, XRD Testing, FTIR Testing, Density Testing, Flame Retardance Testing, And Hardness Testing. Based on the results of porosity testing, it is known that the addition of nanocellulose and barium hexaferrite filler has an effect on the porosity of the composite, which causes the porosity to be deformed, with the lowest porosity area having a variation of 6% nanocellulose + 20% barium hexaferrite of 19.083%. From the density test, it was found that the addition of nanocellulose and barium hexaferrite increased the density value, with the highest density value being 6% nanocellulose + 20% barium hexaferrite at 1.202 g/cm3 . The addition of nanocellulose and barium hexaferrite also increased the hardness value, with the highest hardness value being 6% nanocellulose + 20% barium hexaferrite of 67.98 Shore A. The average value of the burning rate of Silicone Rubber is 0.291 mm/second
