Abstract
This research aims to develop bioplastic as primary packaging or edible film of chitosan biopolymer derived from tiger prawn shells (Penaeus monodon), and to perform physicochemical and mechanical characteristics. An evaluation of the physicochemical properties of plastic films made from chitosan, by modifying the order of the different treatment processes, namely: a) DPMA (deproteination, demineralization, deacetylation), b) DMKA (demineralization, decoloration, and deacetylation) has conducted. The results of scanning FT-IR of the product shows that chitosan has identical spectrum compare of standard compound. Chitosan product from tiger prawn shells was the used as raw material for the manufacture of bioplastics. Experiments variable on the manufacture of edible film is a study of the effect of the use of different plasticizers (glycerol and sorbitol) and carboxylmethylcelullose (CMC) additives to the physicochemical, mechanical characteristics, and edible film functional. The results showed that all the edible film produced has a clear coat with a thickness between 0.05 to 0.3 mm. Meanwhile, the film density is highest at the DPMA + chitosan edible film sorbitol + CMC with a value of 1.7300 g/cm3. The use of plasticizer sorbitol provides great tensile strength but not too elastic, compared to the glycerol, while an increase in the average CMC can increase tensile strength and %Elongation. The use of different plasticizers and additives CMC does not significantly affect its functional properties, where the value of WVTR (water vapor transmission rate) is relatively the same on both types of edible films, ranging from 3.2409 to 4.8858 g /hr.m2.

Summary
Sejarah Artikel: Diterima Juni 2016 Disetujui November 2016 Dipublikasikan Desember 2016. Produk kitosan dari cangkang udang windu yang dihasilkan, selanjutnya digunakan sebagai bahan dasar untuk pembuatan bioplastik. Variabel percobaan pada pembuatan edible film adalah kajian pengaruh pengunaan plasticizer yang berbeda (gliserol dan sorbitol) dan aditif karboksilmetilselulosa (CMC) terhadap karakteristik fisikokimia, mekanikal, dan fungsional dari edible film kitosan. Sedangkan densitas film yang paling tinggi adalah pada edible film kitosan DPMA + sorbitol + CMC dengan nilai 1,730 g/cm. Penggunaan plasticizer sorbitol memberikan kuat tarik yang besar tetapi tidak terlalu elastis, jika dibandingkan dengan penggunaan gliserol, sedangkan penambahan CMC rata-rata dapat meningkatkan kuat tarik dan % Elongasi. Penggunaan plastisizer berbeda dan aditif CMC tidak terlalu mempengaruhi sifat fungsionalnya, dimana nilai WVTR (water vapour transmission rate) relatif sama dari kedua jenis edible film, yaitu berkisar antara 3,2409-4,8858 g/hari.m2
