Tahapan Proses Produksi Dan Karakterisasi Bioplastik Dari Limbah Tongkol Jagung
Get PDFPlastic is the dominant packaging used by the public, so it has the potential to damage the environment. It is necessary to synthesize raw materials for making plastics that are degraded by microorganisms, namely bioplastics. Bioplastics are packaging materials that are synthesized from natural raw materials so that they can be degraded in the environment. The raw material used is corncob because it is abundant and the benefits are not maximized. Research is needed to examine the stages of the production process and the characterization of bioplastics from corncob waste. The purpose of this study was to examine the stages of the production process and the characterization of bioplastics from corncob waste. This study used a laboratory experimental method with descriptive analysis. The production of bioplastics consists of the stages of making cellulose, cellulose acetate, and bioplastics using the solution casting method. The stages of cellulose isolation include hydrolysis, delignification, pulping, and bleaching, which showed an increase in cellulose content from 32.14% to 79.36%. Cellulose is acetylated to become cellulose acetate and has an acetyl content of 11.70 ± 0.40% with a yield of 121.16 ± 0.98%. The production of bioplastics uses a composition of cellulose acetate and chitosan at 50%:50% (w/w) successively. The resulting bioplastic has a thickness of 0.345 ± 0.024 mm, a density of 0.83 ± 0.03 g/cm3, a moisture content of 13.13%, a biodegradation value of 95.19%, a water resistance of 205.57%, and is transparent. The mechanical properties of bioplastics include a tensile strength of 22.3 N/m, an elongation of 21.11%, and a modulus of elasticity of 0.307 Mpa.Plastic is the dominant packaging used by the public, so it has the potential to damage the environment.

a MODEL ISOTERM ADSORPSI LANGMUIR PADA ANALISIS DAYA SERAP IODIUM
No full textIodine absorption analysis is used as an analysis in determining the quality of the adsorbent before its application. This analysis is able to identify the maximum amount of adsorbate that can be bound by an adsorbent. In addition, data analysis of iodine absorption can also explain the mechanism of the adsorption process that takes place in an adsorbate through the adsorption isotherm model. So that it can be used as an initial analysis in the manufacture of synthetic adsorption media. In this study, it was found that the absorption value of iodine in the adsorbent increased with lower iodine concentrations. The lowest iodine concentration of 0.025 N can be absorbed the most with a value of 81%. Iodine absorption analysis data obtained is then represented through the Langmuir isotherm model. Based on experimental data the correlation coefficient (R2) in the Langmuir isotherm model has a value of R2 = 0.945. So this model can be used to explain the adsorption mechanism in the analysis of iodine absorption. Through this adsorption model, it can be seen the adsorption mechanism that takes place and the maximum capacity of the adsorbate that is adsorbed. Based on the Langmuir isotherm model, analysis of iodine absorption through the monolayer absorption mechanism. The adsorption mechanism that occurs is the adsorption rate which is proportional to the fraction of empty sites present on the carbon along with the concentration of iodine in the solution. Iodine can be adsorbed to a maximum of 0.58 mg g-1. In other words, the Langmuir adsorption isotherm model can be used in the analysis of iodine uptake as a model that explains the maximum amount of bound adsorbate and the adsorption mechanism that takes place during the analysis.Analisis daya serap iodium dimanfaatkan sebagai salah satu analisis dalam menentukan kualitas adsorben sebelum pengaplikasiannya. Analisis ini mampu mengidentifikasi jumlah adsorbat maksimal yang dapat diikat suatu adsorben. Selain itu, data analisis daya serap iodium dapat pula menjelaskan mekanisme proses adsorpsi yang berlangsung pada suatu adsorbat melalui model isotherm adsorpsi. Sehingga dapat dimanfaatkan sebagai analisis awal dalam pembuatan media adsorpsi sintesis. Pada penelitian ini diperoleh nilai serapan iodium pada adsorben semakin meningkat dengan semakin rendahnya konsentrasi iodium. Konsentrasi iodium paling rendah sebesar 0,025 N dapat terserap paling besar dengan nilai 81%. Data analisis daya serap iodium yang diperoleh kemudian direpresentasikan melalui model isotherm Langmuir. Berdasarkan data eksperimen koefisien korelasi (R2) pada model isotherm Langmuir memiliki nilai R2 = 0,945. Sehingga model ini dapat digunakan untuk menjelaskan mekanisme adsorpsi pada analisis daya serap iodium. Melalui model adsorpsi ini, dapat diketahui mekanisme adorpsi yang berlangsung dan kapasitas maksimal adsorbat yang teradsopsi. Berdasarkan model isotherm Langmuir, analisis daya serap iodium melalui mekanisme penyerapan monolayer. Mekanisme adsorpsi yang terjadi adalah laju adsorpsi yang sebanding dengan fraksi situs kosong yang ada pada karbon bersama dengan konsentrasi iodium dalam larutan. Iodium dapat teradsorpsi maksimal sebesar sebesar 0,58 mg g-1. Dengan kata lain, model isotherm adsorpsi Langmuir dapat digunakan dalam analisis daya serap iodium sebagai model yang menjelaskan jumlah maksimal adsorbat yang terikat dan mekanisme adsorpsi yang berlangsung selama analisi
