Utomo, Dean Prastya (2015) Pemanfaatan Pati Talas Belitung (Xanthosoma Sagittifolium) Sebagai Bahan Utama Pembuatan Plastik Biodegradable (Kajian Suhu Dan Lama Pengeringan. Sarjana thesis, Universitas Brawijaya.
Abstract
Talas Belitung (Xanthosoma sagittifolium) berpotensi tinggi sebagai bahan baku plastik biodegradable mengingat kandungan karbohidratnya yang cukup tinggi terutama pati sebesar 77,90%. Pati talas belitung dipilih sebagai bahan plastik karena murah dan mudah terdegradasi oleh mikroorganisme dalam tanah. Plastik berbahan dasar pati memiliki kelemahan yaitu pada sifat fisik dan mekaniknya. Perlakuan suhu dan waktu pengeringan dapat memperbaiki sifat mekanik dan tingkat biodegradasi dari plastik biodegradable. Tujuan penelitian adalah menganalisa sifat fisik dan mekanik terbaik serta tingkat biodegradasi dari plastik biodegradable pati talas belitung. Rancangan yang digunakan adalah Rancangan Acak Kelompok Faktorial dengan 2 faktor yang masing-masing terdiri dari 3 level dengan 2 ulangan yaitu suhu (S) (40°C, 50°C dan 60°C) dan waktu (W) (2jam, 3jam, dan 4jam). Parameter penilaian yaitu kuat tarik, elastisitas, swelling, kadar air, ketebalan, transmiisi uap air dan tingkat biodegradasi. Data yang diperoleh diolah dengan ANOVA, selanjutnya dengan uji BNT bila terdapat beda nyata pada faktor dan DMRT bila terdapat beda nyata pada kombinasi perlakuan. Sifat fisik dan mekanik terbaik didapat pada suhu 60°C dan waktu 2 jam dengan nilai kuat tarik sebesar 21,6 Pa, elastisitas sebesar 25%, swelling sebesar 1,26 %. transmisi uap air 0,044 g.mm/m.24jam, ketebalan 0,124 mm, kadar air 0,40 % serta tingkat biodegradasi di hari ke 10 dengan persentase sebesar 75%.
English Abstract
Belitung taro (Xanthosoma sagittifolium) has high potential as a biodegradable plastic raw materials in view of the relatively high carbohydrate content, especially starch amounted to 77.90%. Belitung taro starch chosen as the plastic material because it is cheap and easily degraded by microorganisms in the soil. Starch based plastic has the disadvantage of the physical and mechanical properties. Treatment temperature and drying duration can improve the mechanical properties and biodegradation rate of biodegradable plastic. The research objective was to analyze the best physical and mechanical properties and biodegradation rate of biodegradable plastic belitung taro starch. This study used a Randomized Completely Block Design (RCBD), which consist of 2 factors with 3 levels with 2 replications, the factors is temperature (S) were (40°C, 50°C and 60°C) and duration (W) were (2 hours, 3 hours, and 4 hours). Valuation parameters is tensile strength, elasticity, swelling, moisture content, thickness, water vapor transmission and rate of biodegradation. The data obtained were processed by ANOVA, then with LSD when there is a significant difference in the factors and DMRT when there is a significant difference in the combined treatment. The best physical and mechanical properties obtained at temperature 60°C and drying duration of 2 hours with a value of 21.6 Pa tensile strength, elasticity by 25%, swelling of 1.26%, water vapor transmission g.mm/m.24jam 0.044, 0.124 mm thickness, water content 0.40% The best biodegradation level occurred on the 10th day with the value of percentage is a 75%.
