Perkembangan bioplastik dari sumber daya terbarukan menjadi salah satu fokus utama dalam pembangunan berkelanjutan berbasis zero-waste system. Penelitian terkait analisis sifat fisikokimia bioplastik kombinasi pati bji durian-selulosa dan pati tapioka-selulosa dengan penambahan PVA dan ZnO telah dilakukan. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan pati dan selulosa terhadap daya serap air dan kemampuan biodegradasi pada bioplastik. Analisis gugus fungsi dilakukan dengan menggunakan instrumen FTIR menunjukkan pola puncak serapan pada 3616 cm-1, 1066 cm-1, 2966 cm-1, 1155 cm-1, 1292 cm-1, dan 570 cm-1, perubahan amplitudo pada beberapa puncak serapan dikarenakan pembentukan ikatan hidrogen BSC2. Daya serap air menurun seiring bertambahnya pati dan selulosa disebabkan selulosa mereduksi sifat hidrofilik dari bioplastik yang hanya terbuat dari pati, sehingga bioplastik lebih tahan terhadap air. Kemampuan biodegradasi bioplastik dengan komposisi 78% pati dan 4,7% selulosa menunjukkan laju degradasi yang paling besar pada hari ke-9. Hasil penelitian menunjukkan potensi besar bioplastik yang ramah lingkungan dan sesuai SNI, sekaligus memberikan dasar bagi pengembangan material bioplastik yang lebih efisien dan berkelanjutan.

Hanny Nabila Z. Elriyadh. (2024). Analysis of Differences in Physicochemical Properties of Bioplastic Combination of Durian Seed Starch-Cellulose and Tapioca Starch-Cellulose. [Thesis. Syiah Kuala University]. Under the guidance of Dr. Abdul Gani, M.Si., and Dr. Rahmad Rizki Fazli, S.Pd., M.Si. The development of bioplastics from renewable resources is one of the main concerns in sustainable development based on a zero-waste system. Research related to the analysis of physicochemical properties of bioplastics of durian starch-cellulose and tapioca starch-cellulose combinations with the addition of PVA and ZnO has been conducted. This study aims to analysis the effect of the addition of starch and cellulose on water absorption and biodegradability of bioplastics. Functional group analysis conducted using FTIR instrument showed the pattern of absorption peaks at 3616 cm-1, 1066 cm-1, 2966 cm-1, 1155 cm-1, 1292 cm-1, and 570 cm-1, the change in amplitude at several absorption peaks due to the formation of BSC2 hydrogen bonds. Water absorption decreases as starch and cellulose increase due to cellulose reducing the hydrophilic nature of bioplastics made only from starch, so that bioplastics are more resistant to water. The biodegradation ability of bioplastics with a composition of 78% starch and 4.7% cellulose showed the greatest degradation rate on day 9. The results show the great potential of environmentally friendly and SNI-qualified bioplastics, while providing a basis for the development of more efficient and sustainable bioplastic materials.
