“…Films with a high opacity are very good for protection against light exposure, especially for products sensitive to light-catalyzed degradation. (Kumoro & Purbasari, 2014). Morphological observations on the surface of biodegradable plastic were carried out using an electron microscope (SEM) with a magnification of 3,000X (Figure 4b).…”

The use of plastics made from petrochemicals has a bad environmental impact. One of the efforts to overcome this is using microalgae Navicula sp. as a raw material for making biodegradable plastics. Navicula sp. TAD01 is a type of marine microalgae that is spread Inner Bay of Ambon and can be used to manufacture biodegradable plastics. In this study, biodegradable plastic was synthesized from the biomass of Navicula sp. TAD01, characterization and degradation test. The method used in this research includes three stages. Navicula sp. TAD01 cells were grown in the first stage to obtain biomass. The second stage is making biodegradable plastic from the biomass of Navicula sp. TAD01. The last step is to characterize biodegradable plastics and perform a degradation test. Cultivation of Navicula sp. TAD01 obtained dry biomass of 6.4398 grams, with a productivity value of 0.0524 gL-1h-1. The biodegradable plastic made has a slippery texture and a greenish opaque color with a thickness of 0.05 mm. It has tensile strength and elongation values at break of 1.36 MPa and 30.7%, respectively. The results of the analysis of the biodegradation test on this biodegradable plastic film have a mass loss percentage value of 85.27% with an immersion time of 10 days. This shows that Navicula sp TAD01 has the potential to be used as an ingredient in the manufacture of biodegradable plastics that can degrade well

“…Wattimena et al (2016) stated addition glycerol also effects on the tensile strength of bioplastics. Kumoro and Purbasari (2014) reported bioplastic production using addition glycerol 15% has a tensile strength value of 20.65 MPa. Tensile strength in all treatments did not meet the bioplastic quality standard (SNI 7188.7:2016), where the tensile strength value should be a minimum of 13.7 MPa.…”

“…No indication of heavy metal, Cd<0.5 ppm, Pb<50 ppm, Hg<0.5 ppm, Cr⁶⁺<50 ppm, and did not contain azo dyes. Kumoro and Purbasari (2014) reported production of bioplastic from tapioca flour and rice flour resulted in FTIR showing the presence of an amide I group (a protein containing C=O bonds) and a spectral energy band with a position of cm⁻¹ is a marker of the existence of amide III groups found at 1 200 and 1 350 cm⁻¹. Zaroh and Widyastuti (2019) reported bioplastic production from tapioca pulp to have FTIR results with functional O-H, C-H, C=O, C=C, C-O, and = C-H, it means that bioplastic can be graded because bioplastic material with 30% chitosan and temperature value of 95˚C.…”

“…Tapioca flour is pure starch obtained by extraction from cassava milling, the amylopectin content will provide optimal stickiness (Azieyanti et al, 2019). Kumoro and Purbasari (2014) have successfully carried out bioplastics made from tapioca flour and aking rice (Haryanto and Saputri (2016); Haryanto and Titani (2017); Karim and Musta (2019).…”

Bioplastik merupakan plastik yang dapat terurai karena sifatnya yang dapat kembali ke alam. Penelitian ini bertujuan untuk mengkaji komposisi yang optimal untuk pembuatan bioplastik dengan berbagai variasi komposisi bahan baku. Perbandingan komposisi limbah kulit pisang raja:tepung tapioka:gliserol berturut-turut 1:10:7,5 (sampel A) dan 1:13:11,25 (sampel B). Perbandingan komposisi limbah nasi:tepung tapioka:gliserol pada sampel C dan D masing-masing adalah 1:10:7,5 dan 1:13:11,25. Bioplastik diproses dengan cara komposit limbah kulit pisang raja atau nasi yang dikeringkan sampai kadar air 70%. Aquades sebanyak 30 mL ditambahkan pada bioplastik dan dipanaskan sampai mengental. Bioplastik dicetak dalam loyang saat masih panas dan di oven dengan suhu 117˚C, lalu di dinginkan pada suhu ruang. Komposisi yang optimal dari pembuatan bioplastik terdapat pada sampel B dengan nilai uji biodegradasi 58% dan memiliki kandungan bioplastik dengan gugus fungsi O-H, C-H, C=O, C=C, C-O dan =C-H pada hasil uji FTIR. Nilai baku mutu uji kuat tarik dan uji pemanjangan saat putus pada sampel B memiliki nilai berturut-turut sebasar 10,9 MPa dan 29%.

<table class="NormalTable"><tbody><tr><td width="200"><span class="fontstyle0">Research on the manufacture of bioplastics from bran is one of the efforts to<br />develop the development of environmentally friendly plastics because they can be<br />decomposed by microorganisms. In addition, this study also seeks to reduce<br />environmental pollution due to the disposal of rice mill waste. The research was<br />conducted by mixing rice bran with water, sulfuric acid and sorbitol in various<br />variations of the ratio of sorbitol and bran 1:10; 2:10; 3:10; 4:10 and 5:10 (v:b).<br />Furthermore, chitosan was added as a reinforcement with variations in the<br />addition of chitosan with bran, namely 4:10; 6:10; 8:10; 10:10 and 12:10 then<br />printed and analyzed for dance strength, swelling and surface morphology. The<br />test results showed the highest tensile strength value in the ratio of sorbitol and<br />bran 5:10 and chitosan bran 10:10 with the highest tensile strength value of 64.27<br />MPa and 25% swelling value.
