Abstract

Bioplastik merupakan plastik berpolimer berbahan dasar pati yang mudah terdegradasi oleh mikroorganisme, sehingga dapat dijadikan sebagai alternatif penggunaan plastik konvensional. Pada Penelitian ini dilakukan proses pembuatan bioplastik berbahan dasar pati singkong dengan penggunaan gliserol sebagai plastiscizer dan digunakan CNT jenis MWCNTs (Multi Wall CNTs) sebagai penguat dengan variasi komposisi 0%, 1%, 2% dan 3%. Bioplastik dibuat dengan metode kering (dry blending) dengan tahapan pre-mixing, mixing, hot press dan cold press. Karakteristik bioplastik pati/CNT meliputi kuat tarik, biodegradasi dan morfologi . Hasil pengujian menunjukkan bahwa penambahan komposisi CNT mempengaruhi sifat mekanik bioplastik. Nilai optimum kuat tarik terjadi pada penambahan CNT 2% sebesar 13,52 MPa. Hasil uji biodegradable menggunakan jamur Aspergillus niger membuktikan bioplastik pati/CNT dapat terdegradasi dengan baik. Hasil karakteristik morfologi berupa hasil SEM menunjukkan bahwa bioplastik pati/CNT 3% memiliki retakan dan mengakibatkan kuat tarik menurun. Hasil uji FTIR menunjukkan adanya gugus fungsi baru C≡C karena adanya penambahan CNT.

Additional Information: Bioplastics are starch based polymers that are easily degraded by microorganisms, so they can be used as an alternative to the use of conventional plastics. In this research, bioplastics made from cassava starch was made using glycerol as plastisicizer and used MWCNTs (Multi Wall CNTs) CNT as reinforcement with variations in the composition of 0%, 1%, 2% and 3%. Bioplastics are made with a dry method (dry blending) with stages of pre-mixing, mixing, hot press and cold press. Characteristics of bioplastic starch/CNT include tensile strength, biodegradation and morphological. The test results show that the addition of CNT composition affects the mechanical properties of bioplastics. The optimum value of tensile strength occurred in the addition of 2% CNT at 13.52 MPa. Biodegradable test results using the Aspergillus niger mushroom prove that bioplastic starch / CNT can be degraded well. The results of morphological characteristics in the form of SEM results showed that 3% bioplastic starch/CNT had cracks and resulted in decreased tensile strength. FTIR test results indicate the presence of a new functional group C≡C because of the addition of CNT.
