Abstract

Bioplastic is a plastic that can be decomposed because it can return to nature. This study aims to examine the optimal composition for the of bioplastics with various compositions of raw material. Comparison of the composition of waste banana peel:tapioca flour:glycerol, respectively 1:10:7,5 (sample A) and 1:13:11,25 (sample B). The ratio of the composition of waste rice:tapioca flour:glycerol in sample C and D is 1:10:7,5 and 1:13:11,25, respectively. Bioplastics are processed by using a composite of banana peel or rice waste which is dried to a moisture content of 70%. 30 mL of distilled water was added to the bioplastic and heated until thickened. The bioplastic is molded in a baking sheet while it is still hot and in an oven at 117˚C, then cooled at room temperature. The optimal composition of bioplastic is found in sample B with a biodegradation test value of 58% and contains bioplastics with functional groups O-H, C-H, C=O, C=C, C-O and =C-H in the FTIR test results. The quality standard values ​​for the tensile strength test and elongation test at break in sample B have values ​​of 10.9 MPa and 29%, respectively.

Abstract

Bioplastics is a plastic composite material that can decompose quickly and is environmentally friendly when interacting with soil and microorganisms. The aims of the research are: to examine the optimal composition of bioplastics made from tapioca waste by adding blood clam shell chitosan and glycerol, to determine the quality of production bioplastics from tapioca waste with the addition of blood clam shell chitosan and glycerol, and to determine the chemical content of the clam shells. bioplastic function of tapioca with the addition of blood clam shell chitosan and glycerol. The method used is experimental. Production of bioplastic by mixing waste tapioca flour, chitosan, and glycerol with a composition of 65%:35%:5mL, 70%:30%:5mL, and 75%:25%:5mL and additional water. The sample was put into a water bath and stirred at a temperature of 80oC for 15 minutes. Bioplastics were printed in aluminum foil, dried at 100oC for 90 minutes and cooled at room temperature for 6 hours. Laboratory test samples with tensile strength, elongation at break, FTIR, and biodegradation tests according to SNI 7188.7:2016 in the category of bioplastic easily decomposed. The results of the tensile strength on PBA1 samples were 0.75 Mpa, PBA2 samples were 0.54 Mpa, and PBA3 samples were 0.34 Mpa. Test value for elongation at break the PBA1 sample is 23.68%, the PBA2 sample is 15.33%, and the PBA3 sample is 12.12%. The sample test results do not meet the quality standard value of SNI 7188.7:2016 for the bioplastic category. The optimal composition of bioplastics is found in the PBA2 sample using tapioca flour as raw material with chitosan and glycerol as much as 70%:30%:5mL with a tensile strength 0.54%, an elongation at break 15.33%, biodegradation of 43%, and has a bioplastic content with functional groups (C=C), (CO), (CH),(OH), (C=C), and (CH2)n in the FTIR test results.

Abstract

Bioplastic material is derived from natural materials that microorganisms can break down producing water and carbon dioxide. With the expansion of chitosan, CaCO3 from Anadara granosa and glycerol, the structure of the materials utilized to create bioplastics from custard squander. The technique utilized was a trial, which started with producing chitosan and CaCO3 from Andara granosa. The production of bioplastics was completed with custard squander composites blended in with Anadara granosa with an organization of 80% : 20% with the expansion of CaCO3 and glycerol. The ratio of CaCO3 and glycerol differed into four creation proportions 0.3 g : 10 mL; 0.3 g : 15 mL; 0.4 g : 10mL; 0.4 g : 15 mL. Tensile strength upsides of tests 1 10.98 MPa. The elongation test values are sample 1 23.79%, sample 2 22.00%, sample 3 19.16%, and sample 4 23.80%. In the after effects of biodegradation tests with soil media, the worth is near sample 2 which can be evaluated by 51.5% with an ideal structure of the proportion of CaCO3 and glycerol 0.3 g : 15 mL.

Abstract

Leachate, which comes from waste landfills, contains high levels of organic and inorganic matter. Constructed Wetland technology is a suitable alternative for leachate treatment. This technology is easy to apply, relatively cost-effective, and can achieve optimal reduction results for treating and controlling leachate, thereby reducing its environmental impact. The objective of this study was to treat the BOD concentration and COD in leachate using a Constructed Wetland. Data collection was performed by conducting leachate experiments for Constructed Wetland treatment using Hippochaetes lymenalis plants based on variations in residence time and media height. There was a control group (R1) without any media or plants. The variation combination included R2 (containing 10 cm gravel and 10 cm fertile soil) and R3 (containing 5 cm gravel and 15 cm fertile soil). Residence times were set at 0, 7, 14, and 21 d. This research showed that the reactor with growth media consisting of 10 cm gravel and 10 cm fertile soil had 55% and 85% BOD and COD removal efficiencies, with final BOD concentrations and COD values of 273 mg/L and 1,321, respectively. The reactor with growth media consisting of 5 cm gravel and 10 cm fertile soil had 74% and 95% BOD and COD removal efficiency, with the final BOD concentration and COD at 159 mg/L and 432, respectively.
