dc.description.abstract | Plastik telah menjadi salah satu penyumbang sampah terutama di
lingkungan perairan. Penggunaan plastik sebagai kemasan telah menjadi gaya
hidup di banyak negara yang memicu kebutuhan plastik yang cukup tinggi.
Pembuatan bioplastik berbasis agar masih memiliki sifat fisik yang kurang baik
seperti kaku dan kurang elastis. Penambahan material lain seperti kitosan dan
sorbitol diharapkan dapat memperbaiki sifat bioplastik yang dihasilkan. Penelitian
ini bertujuan untuk menentukan formula terbaik dari campuran kitosan dan agar
sebagai bahan pembuatan bioplastik dengan jumlah plasticizer sorbitol yang
berbeda serta mengetahui karakteristik sifat fisikokimia material bioplastik yang
dihasilkan. Tahapan penelitian meliputi pencampuran kitosan, agar, dan sorbitol
(0%, 1%, 1,25%, dan 1,5%), pencetakan bioplastik dan karakterisasi bioplastik.
Karakterisasi bioplastik meliputi uji ketebalan, uji kuat tarik dan elongasi, daya
serap air, analisis gugus fungsi dengan Fourier Transform Infra Red Spectroscopy,
dan uji degradasi. Bioplastik dengan formula terbaik yaitu perlakuan 1,25% yang
menghasilkan nilai ketebalan 0,096±0,004 mm, daya serap air 18,80±0,94%, kuat
tarik 18,83±2,93 MPa, dan elongasi 95,89±12,62%. Waktu yang diperlukan
bioplastik 1,25% untuk terdegradasi sempurna yaitu selama 20 hari. | id |
dc.description.abstract | Plastic has become one of the contributors to waste, especially in the aquatic
environment. The use of plastic as packaging has become a lifestyle in many
countries which triggers a high demand for plastic. The manufacture of agar-based
bioplastics still has poor physical properties such as stiffness and lack of elasticity.
The addition of other materials such as chitosan and sorbitol are expected to
improve the properties of the bioplastics produced. This study aims to determine
the best formula for the mixture of chitosan and agar as a bioplastic material with
different amounts of sorbitol plasticizer and to determine the characteristics of the
physicochemical properties of the resulting bioplastic material. The research
stages included mixing chitosan, agar, and sorbitol (0%, 1%, 1.25%, and 1.5%),
bioplastic molding and bioplastic characterization. Bioplastic characterization
includes thickness test, tensile strength and elongation test, water absorption,
functional group analysis with Fourier Transform Infra Red Spectroscopy and
degradation test. Bioplastics with the best formula was 1.25% treatment which
produces a thickness value of 0.096±0.004 mm, water absorption of 18.80±0.94%,
tensile strength of 18.83±2.93 MPa, and elongation of 95.89±12.62%. The time
required for 1.25% bioplastic to degrade completely was 20 days. | id |
