“…Excessive filler can reduce the mechanical properties of the film, and aggregation will weaken the Engineering Headway Vol. 6 properties of the film and the network regularity of the film structure. The addition of proportional and appropriate TiO2 nanoparticles increases tensile strength and reduces elongation due to interactions between various molecules.…”

The manufacture of bioplastic from potato starch (Solanum tuberosum L.) and glycerol from waste cooking oil with the addition of TiO2 has been done by varying the concentration of TiO2. This study aims to study the effect of the addition of TiO2 on the physical and mechanical properties of potato starch and glycerol from leech oil. The research was conducted by making glycerol from waste cooking oil, making bioplastic film with various concentrations of TiO2 (0; 1; 2; 3 and 4%), characterization of bioplastic, which includes physical and mechanical properties. The addition of TiO2 as a bioplastic filler can affect its physical and mechanical properties. The result showed that each addition of 1% TiO2 increased the thickness by 22,966 microns, the tensile strength value by 0.0853 N/mm2, the average Young’s modulus by 0.0599 MPa, and decreased elongation by 5.0987%. The best bioplastic mechanical test results were produced at a starch composition of 2.5 grams and 2% (w/w) of TiO2 particles.

“…Plasticizer seperti gliserol juga merupakan pelarut organik dengan titik didih tinggi hal ini menyebabkan resin yang keras mendapatkan akumulasi gaya intermolekuler pada rantai panjang yang menurun sehingga bioplastik yang dihasilkan lentur, melunak serta rantai pemanjangan resin bertambah (Dermawan et al, 2020). Penggunaan gliserol dalam jumlah yang tinggi akan meningkatkan kelarutan sehingga bioplastik bersifat hidrofilik yaitu larut dalam air (Nurlaila & Purnomo, 1970).…”

Plastik merupakan rantai polimer dengan rantai atom yang panjang dan saling mengikat satu sama lain. Plastik banyak digunakan dalam kehidupan sehari-hari karena plastik memiliki sifat yang kuat, elastis dan memiliki harga yang terjangkau. Namun, plastik saat ini sulit untuk diurai sehingga perlu inovasi dengan penggunaan bioplastik. Bioplastik merupakan plastik organik yang mampu dirurai oleh mikroorganisme. Pembuatan bioplastik menggunakan pati kulit kentang yang diekstraksi. Larutan bioplastik dicampurkan dengan asam asetat 1% dan gliserol sebagai plasticizer. Larutan bioplastik dipanaskan pada temperatur 70 °C, 80 °C dan 90 °C untuk mengetahui pengaruh temperatur gelatinisasi pada sifat fisik dari bioplastik. Larutan bioplastik kemudian dicetak dan dikeringkan. Setelah itu lembaran film bioplastik dilakukan uji sifat mekanik meliputi uji kuat tarik, perpanjangan putus, ketebalan dan daya serap air. Temperatur gelatinisasi terbaik temperatur 80 °C hal ini dikarenakan hasil pengujian sampel menunjukan nilai tertinggi. Seperti pada uji kuat tarik nilainya mencapai 10,273 MPa. Pada uji perpanjangan putus pada bioplastik dengan temperatur gelatinisasinya 80 °C mencapai nilai 11,13%. Uji ketebalan juga menunjukan nilai tertinggi pada temperatur 80 °C dengan nilai 185,5 nanometer. nilai penyerapan air tertinggi hingga 70,5% juga didapatkan pada suhu ini. Nilai uji sifat mekanik bioplastik kulit kentang belum memenuhi SNI 7188.7:2016.

The development of bioplastic films is one of the efforts to reduce plastic waste. The polymer used as the basic material for making bioplastic films is starch. Potato peel waste can be repurposed by extracting its starch content. This research has the purpose to investigate the influence of adding glycerol and spirulina on the characteristics of bioplastic films made from potato peel starch, and to ascertain the optimum composition of raw materials. Bioplastics were produced by casting method from potato peel starch with variations of glycerol and spirulina. The bioplastic composition in this research includes K0 (0 ml glycerol and 0 grams spirulina), K1 (2.5 ml glycerol and 0.3 grams spirulina), K2 (1.25 ml glycerol and 0.3 grams spirulina), K3 (2.5 ml glycerol and 0.15 grams spirulina), and K4 (1.25 ml glycerol and 0.15 grams spirulina). The characteristics of bioplastic films include thickness testing, tensile strength, elongation at break, and degradation. The results from the characterization of bioplastic films indicate that the addition of glycerol and spirulina is inversely proportional to the tensile strength produced, meaning it decreases. However, the addition of glycerol and spirulina is directly proportional to the percentage of elongation produced, meaning it increases. The addition of spirulina has an impact on the degradation time of bioplastic films. The optimal raw material ratio in this research is found in sample K4, with a tensile strength value of 23.038 MPa, elongation at break of 4.385%, thickness of 0.1367 mm, and complete degradation occurring on the sixth day.
