“…It is indicated by the physical form of the bioplastic film produced in the 6 gram clay filler variation tend to cracked. The same thing was said by previous researchers Melani (2017) where too much clay filler concentration produce bioplastics that are not good or break easily.…”

“…This is because clay is a filler made from organic raw material which is very easily biodegradable or degraded by soil. The same thing was also conveyed by Melani (2017) where clay fillers which are made from clay when used in bioplastic mixtures will easily decompose Whereas on chitosan filler, the more chitosan added, the slower the degradation process. This is in accordance with the research of Oetary (2019) because chitosan is an antimicrobial agent which slows down the work of decaying bacteria, even though chitosan is an easily decomposed material.…”

Bioplactic from banana corm and glycerol has been studied in this research. In addition, the physical chemical properties of it has been improved by adding chitosan, clay and CMC as filler and glycerol as plasticizer. Plastic that produced form organic material such as starch usually has poor properties in physical and mechanical. Composition variation of chitosan, clay and CMC as filler then combined by variation of glycerol as plasticizer have produced significant improve of the bioplastic physical properties. Properties of the bioplastic that studied in this research was focused to biodegradation, elongation, and tensile strength. The addition of fillers and plasticizers is carried out to produce a better bioplastics. This study used 3 variations of the filler composition : 4, 5, and 6 grams and 2 variations of the plasticizer composition: 1 ml and 2 ml. The bioplastics that produced were tested for tensile strength, elongation, and biodegradation of the soil for 7 days. The best tensile strength results is 8.43 MPa for bioplastic that using CMC fillers. On the other side, the best elongation percentage is 9.87% for bioplastic which using CMC fillers. The bioplastic that added Clay as filler can be degraded up to 100% in 7 days.

Plastik merupakan bahan yang banyak digunakan dalam kehidupan sehari-hari, tetapi mencemari lingkungan karena plastik tidak dapat diuraikan oleh lingkungan. Penelitian mengenai bioplastik diperlukan untuk bahan alternatif plastik yang mudah terurai. Karagenan dan amilum merupakan polisakarida yang berpotensi sebagai bahan pembuatan bioplastik. Tujuan dari penelitian ini untuk menentukan perbedaan karakteristik (ketebalan, kuat tarik dan elongasi) bioplastik berbahan dasar karagenan dan gliserol terhadap pertambahan konsentrasi amilum. Metode penelitian yang digunakan yaitu Eksperimental Laboratorium. Karagenan diperoleh dari ektraksi K. alvarezii yang berasal dari perairan Jepara, Jawa Tengah. Bioplastik dibuat dengan gelatinasi amilum (1; 2; 3; dan 4 g) dalam 50 ml akuades pada suhu 90ºC selama 15 menit dalam erlenmeyer menggunakan Hot Plate Stirrer. Gliserol 20% ditambahkan dan dihomogenkan selama 5 menit. Suhu diturunkan hingga 70ºC, selanjutnya karagenan 1 g dan akuades ditambahkan hingga volume 150 ml dihomogenkan selama 45 menit. Bioplastik dicetak dan dikeringkan di oven selama 18 jam pada suhu 50ºC. Hasil penelitian menunjukkan bahwa karakteristik bioplastik κ-karagenan dengan penambahan amilum yaitu memiliki kuat tarik 6,42-11,47 MPa, nilai elongasi 7,03-21,88% dan ketebalan 0,13-0,25 mm. Elongasi konsentrasi amilum 1 g telah memenuhi standar SNI. Parameter yang sesuai dengan standar Japanese Industrial Standard yaitu parameter kuat tarik dan ketebalan. Plastic is a material that is widely used in everyday life, but it pollutes the environment because plastic cannot be decomposed by the environment. Research on bioplastics needs to get alternative materials for plastics that are easily biodegradable. Carrageenan and starch are polysaccharides that have the potential as materials for making bioplastics. This study aimed to determine differences in characteristics (thickness, tensile strength, and elongation) of bioplastics based on carrageenan and glycerol because of increased starch concentration. The research method used is Experimental Laboratory. Carrageenan from the extraction of K. alvarezii from the waters of Jepara, Central Java. Bioplastics were prepared by gelatinization starch (1; 2; 3; and 4 g) in 50 ml of distilled water at 90ºC for 15 minutes in an Erlenmeyer using a Hot Plate Stirrer. Glycerol 20% was added and homogenized for 5 minutes. Lower the temperature to 70ºC, then add 1 g of carrageenan and distilled water until the volume is 150 ml, after that homogenize it for 45 minutes. The bioplastics were molded and dried in the oven for 18 hours at 50ºC. The results showed that the characteristics of κ-carrageenan bioplastic with the addition of starch had a tensile strength of 6.42-11.47 MPa, an elongation value of 7.03-21.88% and a thickness of 0.13-0.25 mm. The elongation of starch concentration of 1 g is in accordance with the SNI standard. Parameters that comply with the Japanese Industrial Standard are the tensile strength and thickness parameters.

Bioplastik menjadi salah satu alternatif pengunaan plastik yang ramah lingkungan karena mudah terurai. Pada penelitian ini digunakan pati umbi talas (Colocasia esculenta L.) dengan campuran asam sitrat, plasticizer gliserol, sedangkan Fillernya clay dan chitosan. Tujuan penelitian ini adalah mengetahui bentuk fisik bioplastik, kuat tarik (tensile strength) dan pemanjangan (elongasi) bioplastik sesuai kualitas SNI serta kemampuan bioplastik ini dapat terurai (biodegradable) dalam waktu yang relatif singkat. Penelitian ini berlangsung dari tanggal 26 Juli-30 September 2021 di laboratorium FKIP KIMIA Universitas Nusa Cendana Kupang dan Laboratorium Biologi SMAS Katolik Regina Pacis Bajawa. Metode penelitian yang digunakan Melt Intercalation dengan sedikit inovasi penambahan asam sitrat dengan variasi pada filler clay dan chitosan yaitu 0,2gr, 0,4gr, 0,8gr, dan 1,0gr. Metode pengolahan data secara kualitatif dan kuantitatif berdasarkan hasil penelitian. Data yang diperoleh kemudian dianalisis bentuk fisik dan kemampuan biodegradable, kemudian dilakukan uji kuat tarik dan persen pemanjangan menggunakan persamaan fisika. Hasil penelitian pada filler clay 0,4gr yang menunjukkan bentuk fisik permukaan halus dan tidak retak. Hasil uji tarik yang terbaik diperoleh pada sampel clay 0,4gr, dengan kekuatan tarik 4N = 37,5MPa. Hasil uji tarik ini sesuai SNI dimana nilai kuat tarik berkisar 24,7-302MPa. Persen pemanjangan pada semua variasi filler clay maupun chitosan memenuhi kriteria SNI dimana nilai persen pemanjangan berkisar 21-220% dan tertinggi persen elongasi terdapat pada chitosan 0,4gr dengan nilai pemanjangan adalah 150%. Hasil uji penguraian bioplastik melalui metode perendaman sampel dalam aquades selama 48 jam, diperoleh hasil adanya penurunan berat bioplastik akibat aktivitas mikroorganisme.
