Durian Seed

Pada penelitian ini biji durian digunakan sebagai sumber pati dalam pembuatan plastik biodegradable. Penelitian ini bertujuan untuk mengetahui pengaruh jenis dan jumlah filler terhadap sifat biodegradable, sifat mekanik dan sifat water absorbtion pada plastik biodegradable berbasis pati biji buah durian. Plasticizer yang digunakan dalam penelitian ini adalah sorbitol  40%, sedangkan filler yang digunakan adalah Kalsium silikat (Ca2SiO4) dan Kalsium karbonat (CaCO3) dengan variable konsentrasi 2%, 4%, 6%, dan 8%. Dari hasil penelitian, diperoleh % yield dari pati biji buah durian sebesar 34,57%. Hasil dari plastik biodegradable terbaik dengan karakteristik transparan, tidak ada gelembung, lentur serta permukaan yang halus diperoleh pada variabel penambahan filler kalsium karbonat 4%. Hasil uji bio-degradasi paling mendekati standard ASTM D6400 diperoleh pada variabel kalsium karbonat 2%. Pada Uji water absorption hasil terbaik dicapai pada variabel kalsium silikat 8%. Uji tarik hasil terbaik diperoleh pada variabel kalsium silikat 6%.In this study, durian seeds were used as a source of starch in making biodegradable plastics. This study aims to determine the effect of the type and amount of filler on biodegradable properties, mechanical properties, and water absorption properties of biodegradable plastics based on durian fruit starch. The plasticizer used in this study was sorbitol 40%, while the filler used was Calcium silicate (Ca2SiO4) and Calcium carbonate (CaCO3) with variable concentrations of 2%, 4%, 6%, and 8%.. From the research results, the% yield of durian seed starch was 34.57%. The results of the best biodegradable plastic with the characteristics of transparent, no bubbles, flexible and smooth surface were obtained with the addition of 4% calcium carbonate filler variables. The bio-degradation test results closest to the ASTM D6400 standard were obtained in the 2% calcium carbonate variable. In the water absorption test, the best results were achieved at the 8% calcium silicate variable. The best tensile test results were obtained in the 6% calcium silicate variable.
