Abstract

Penelitian ini dilakukan untuk mengembangkan material polimer yang ramah lingkungan dan memiliki sifat mekanik, biodegradabilitas, dan stabilitas termal yang baik. Produk polimer ini menggunakan bahan dasar vinilester dengan variasi pengisi pati gandum, pati kentang, pati ketan, minyak jarak, minyak sawit, dan serbuk limbah ban. Pengujian yang dilakukan yaitu uji morfologi (SEM), uji massa jenis, uji FTIR, uji kekerasan shore D, uji kekuatan tarik, uji TGA, dan biodegradasi. Pengujian sifat kekerasan menunjukan peningkatan nilai kekerasan dengan variasi pengisi pati gandum, pati kentang, dan pati ketan dengan tertinggi pada variasi pati ketan sebesar 71,78 HRR. Pengujian kekuatan tarik menunjukan peningkatan kekuatan tarik dengan variasi pengisi minyak jarak dengan kekuatan tarik sebesar 38,54 MPa. Pengujian stabilitas temperatur menunjukan peningkatan dengan variasi pengisi pati gandum, pati kentang, minyak jarak, minyak sawit dan serbuk limbah ban. Stabilitas temperatur tertinggi terdapat pada variasi pengisi pati kentang dengan T5 403 OC. Kemampuan degradasi meningkat dengan variasi pengisi pati gandum, pati kentang, pati ketan, minyak jarak, dan minyak sawit dengan presentase degradasi tertinggi pada variasi pengisi pati kentang sebesar 0.96% dalam 6 minggu. Berdasarkan pengujian yang telah dilakukan, biobased vinil ester dapat digunakan sebagai kandidat pengganti polimer vinil ester dengan nilai tambah mampu terdegradasi secara alami didalam tanah. ========================================================================================================================This research was done to develop eco friendly polymer material which have a good mechanical properties, biodegradability, and thermal stability. This product using vinylester as a base with weath, potato starch, rice starch, castrol oil, oil palm, and waste rubber tire as a filler variation. Tests performed in this study were included SEM, density, FTIR, hardness shore D, Tensile, TGA, and biodegradable. Hardness test shows that hardness value increase with addition of potato starch, rice starch, and weath starch as a filler variation. The highest hardness value was obtained on rice starch, that was 71.78 HRR. Tensile test shows that the highest tensile properties was obtained on biobased polimer with castor oil as a filler, that was 38.54 MPa. Thermogravimetric analysis shows that the thermal stability are increase with the addition of weath starch, potato starch, castor oil, palm oil, and waste rubber tire as a filler. The highest thermal stability was obtained on biobased polymer with potato starch as a filler, T5 value was 403 OC. Degradability increase with the addition of weath starch, potato starch, rice starch, castor oil, palm oil, and waste rubber tire as a filler, the highest degradation percentage obtained on biobased polymer with potato starch as a filler, that was 0.96% in six weeks. Based on the testing and analysis, biobased polymer vinylester can be a replacement candidate of material polymer vinylester with added value capable to degradation naturally in the soil burial.
