Abstract

fetched live from OpenAlex

Penelitian pengaruh kitosan terhadap sifat barrier edible film tapioka termodifikasi dilakukan. Hal ini dilakukan karena lembaran film yang diperoleh pada penelitian sebelumnya masih memerlukan peningkatan sifat barrier dan kestabilan film pada penyimpanan. Seperti diketahui tapioka bersifat hidrofilik, sehingga perlu campuran bahan yang bersifat hidrofobik. Salah satu bahan yang mempunyai sifat tersebut adalah kitosan, dengan penambahan aditif lain diharapkan dapat memperbaiki sifat film . Tujuan dari penelitian ini adalah untuk mengetahui pengaruh kitosan terhadap sifat barrie r edible film tapioka termodifikasi. Penelitian dilakukan dengan metode pencampuran larutan edible film tapioka termodifikasi dengan larutan kitosan. Variabel yang digunakan adalah penambahan konsentrasi kitosan pada larutan edible film tapioka termodifikasi, dengan menitik- beratkan parameter uji pada nilai laju O 2 TR dan nilai laju WVTR dari edible film yang dihasilkan. Secara umum lembaran film yang dihasilkan masih memiliki laju transmisi uap air ( WVTR ) yang cukup besar (>200 g/m 2 /24 jam) dan memiliki sifat kedap terhadap oksigen yang cukup baik, ditandai dengan rendahnya nilai laju transmisi oksigen ( O 2 TR ) (<1cc/m 2 /24jam). Penggunaan paling optimal 1:0,75 dihasilkan nilai laju WVTR minimum sebesar 215,48 g/m 2 /24 jam dan nilai laju O 2 TR sebesar 0,376 (cc/m 2 /24jam). Pada hasil analisis SEM terlihat bahwa pada penambahan filler kitosan sebesar 75% mempunyai sifat barrier terhadap uap air yang baik, hal ini disebabkan filler kitosan yang ditambahkan sudah merata mengisi pori-pori atau celah ikatan antar polimer yang terbentuk. Penambahan kitosan tidak dapat meningkatkan grade pada JIS Z 1707-1997, Plastic Film for Food Packaging.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
