Abstract
Limbah tongkol jagung yang melimpah di Indonesia mengandung 40% selulosa dan sangat sering digunakan untuk bahan dasar plastik biodegridable dengan keunggulan plastik ini mampu terdegradasi dengan cepat di bandingkan plastik konvensional. Pengujian Degradasi plastik biodegridable dilakukan dengan cara mengubur dalam tanah kompos sehingga sehingga microba dan kandungan dalam tanah kompos mampu mengurainya. Variasi waktu degradasi yang digunakan adalah 1 hari, 3 hari, 5 hari, 7 hari dan 9 hari dan menghasilkan massa yang terdegradasi dari sempel adalah 18,4584%, 32,7977%, 53,7917%, 59,5215%, 68,7382%. Setelah itu dilakukan pengujian FTIR dan DMA dengan tujuan melihat pengaruh Degradasi terhadap gugus fungsi selulosa dan sifat mekanik (modulis elastisitas) pada sempel plastik biodegridable. Gugus fungsi dari plastik biodegredable yang tanpa diberikan perlakuan degradasi dan medapatkan perlakuan variasi degradasi memiliki rentang bilangan gelombang yang sama pada puncak spektra masing-masing sampel, perbedaan hanya pada C-O stretching yang masih terdapat pada plastik biodegredable yang belum diberikan perlakuan degradasi yang menandakan ada gliserol aktif didalamnya. Pada pengujian DMA, nilai modulus simpan pada sampel variasi degradasi 1 hari, 3 hari, 5 hari, 7 hari dan 9 hari berturut-turut adalah 80,3981 MPa, 42,0330 MPa, 40,2482 MPa, 20,5823 MPa dan 15,2126 MPa.
================================================================================================
Corny corncobs waste in Indonesia contains 40% cellulose and very often used for biodegridable plastic base material with the advantage of this plastic is able to degrade quickly compared to conventional plastics. Testing Biodegridable plastic degradation is done by burying it in compost so that the microbes and the content in the compost soil are able to disintegrate it. The degradation time variations used were 1 day, 3 days, 5 days, 7 days and 9 days and resulted in degraded mass from sempel being 18.4584%, 32.7977%, 53.7917%, 59.5215%, 68, 7382%. After that, FTIR and DMA testing were performed to see the effect of Degradation on cellulose functional group and mechanical properties (elasticity modulis) on biodegridable plastic seal. The functional groups of biodegredable plastics without treatment of degradation and treatment of variation of degradation have the same range of wave numbers at the peak of the spectra of each sample, the only difference in stretching CO is still present in biodegredable plastics which have not been given degradation treatment indicating active glycerol inside it. In the DMA test, the stored modulus values in the samples of degradation variations 1 day, 3 days, 5 days, 7 days and 9 consecutive days were 80,3981 MPa, 42,0330 MPa, 40,2482 MPa, 20,5823 MPa and 15 , 2126 MPa.
