Tarigan, Timothy Adi Prima (2021) Pembuatan Plastik Biodegradabel Terhadap Hasil Penyerapan Air Dan Biodegradabilitas Dari Bahan Limbah Pati Kulit Singkong (Manihot Esculenta) Dan Pati Sagu (Metroxylon Sagu). Sarjana thesis, Universitas Brawijaya.
Abstract
Plastik banyak dimanfaatkan dalam kehidupan sehari-hari. Penggunaan plastik biasanya untuk menunjang kebutuhan rumah tangga maupun industri. Namun, penggunaan plastik juga dapat berbahaya bagi lingkungan dan kesehatan manusia. Untuk mengurangi pencemaran lingkungan diperlukan adanya pemanfaatan polimer alami dari monomer organik seperti pati sebagai bahan dasar pembuatan plastik biodegradable (dapat diuraikan) yang mempunyai sifat mekanis yang baik. Plastik biodegradable mampu mengalami dekomposisi menjadi karbondioksida, metana, senyawa anorganik atau biomassa yang mekanismenya didominasi oleh aksi enzimatis dari mikroorganisme yang bisa diukur dengan pengujian standar, dalam waktu spesifik, mencerminkan kondisi penggunaan yang tersedia. Hasil persentase penyerapan air terbesar berada pada bahan dasar pati sagu dengan selisih sebesar 42,78% dengan variabel optimal melalui kombinasi komposit sagu sebesar 4 b/b, ditambah volume gliserol sebesar 0,2 gr/ml serta kadar kitosan sebesar 3% b/b dengan nilai penerapan air mencapai 85,15%. Daya serap air berbeda sesuai dengan komposisi campuran bahan tambahan seperti kitosan, gliserol, asam asetat, dan konsentrasi yang dicampurkan pada setiap bahan. Perbedaan signifikan dari nilai biodegradabilitas antara penggunaan pati limbah kulit singkong (Manihot esculenta) dan pati sagu sebagai bahan pembuatan plastik biodegradable dengan nilai persentase biodegradabilitas tertinggi berada pada penggunaan pati sagu, nilai kelarutan rata-rata sebesar 79,83% dan selisih biodegradabilitas sebesar 20,19%, serta nilai optimal sebesar 75,25% melalui komposit berupa pati sagu/PVA sebanyak 1/3 b/b, gliserol 0,064 ml/gr dan kitosan 4 % b/b.
English Abstract
Plastics are widely used in everyday life. The use of plastic is usually used to support household and industrial needs. However, the use of plastics can also be harmful to the environment and human health. To reduce environmental pollution, it is necessary to use natural polymers from organic monomers such as starch as the basic material for making biodegradable plastics (which can be broken down) which have good mechanical properties. Biodegradable plastics are capable of decomposition into carbon dioxide, methane, inorganic compounds or biomass whose mechanisms are dominated by the enzymatic action of microorganisms which can be measured by standard testing, in a specific time, reflecting the available conditions of use. The results of the largest percentage of water absorption are in the basic ingredients of sago starch with a difference of 42.78% with optimal variables through a combination of sago composites of 4 w / w, plus a glycerol volume of 0.2 g / ml and a chitosan content of 3% w / w with a water application value reaching 85.15%. The absorption of water differs according to the composition of the mixture of additives such as chitosan, glycerol, acetic acid, and the concentration mixed in each ingredient. The significant difference in the biodegradability value between the use of cassava peel starch (Manihot esculenta) and sago starch as a material for making biodegradable plastics with the highest percentage value for biodegradability was the use of sago starch, the average solubility value was 79.83% and the biodegradability difference was 20, 19%, and the optimal value is 75.25% through composites in the form of sago starch / PVA as much as 1/3 w / w, glycerol 0.064 ml / g and chitosan 4% w/w.
