Research on biopolymers in the industrial field is increasing, along with attention to environmental problems. One of the interesting biopolymers is Zein, which is a prolamine protein obtained from corn flour. Zein is a hydrophobic biopolymer and has the ability to make films, has been used in the field of food technology as food packaging. In this research, zein was extracted from Corn Gluten Meal (CGM), a by-product of corn processing. Isolation of zein from CGM using 70% alcohol NaOH and NaHSO 3 for 2 hours at 60 o C produced 70.36% zein protein. The FT-IR spectrum of isolated zein showed absorption peaks at wave numbers 1690 cm -1 and 1490 cm -1 which were absorption peaks for amides I and II. The isolated zein was applied to cotton cloth using the pad-dry-cure method at 150 o C for 2 minutes, with various concentrations: 0, 25, 50, 75, 100, and 125 g/L. The results of the water drop test showed that an increase in the concentration of zein would result in a slower absorption time for cotton. Optimum results were chosen at a zein concentration of 100 g/L resulting in an absorption time of 325 seconds. Testing the contact angle of the zein-treated fabric with a concentration of 100 g/L has a contact angle of 128 o . This shows the fabric is hydrophobic. Zein polymer has the potential to be developed as a water repellent finishing agent in cotton fabrics
随着人们对环境问题的关注，生物聚合物在工业领域的研究越来越多。一种有趣的生物聚合物是玉米蛋白，它是一种从玉米粉中提取的脯胺蛋白。玉米蛋白是一种疏水的生物聚合物，具有成膜的能力，已被应用于食品技术领域作为食品包装。本研究从玉米加工的副产物玉米蛋白粉(CGM)中提取玉米蛋白。用70%乙醇NaOH和nahso3在60℃下分离玉米蛋白2小时，得到70.36%的玉米蛋白。分离得到的玉米蛋白的FT-IR光谱在波数1690 cm -1和1490 cm -1处出现吸收峰，为酰胺I和酰胺II的吸收峰。将分离得到的玉米蛋白以0、25、50、75、100、125 g/L的不同浓度，用垫干固化法在150℃下作用于棉布2分钟。水滴试验结果表明，玉米蛋白浓度的增加会导致棉花吸收时间的减慢。玉米蛋白浓度为100 g/L时，吸收时间为325 s。测试浓度为100 g/L的玉米素处理织物的接触角，接触角为128°。这表明织物是疏水性的。玉米蛋白聚合物具有开发棉织物防水性整理剂的潜力

The adsorption ability of modified chitosan and bentonite for color removal in solutions containing Direct Blue 14 (DB 14)textile dyes was carried out in this study. Modified chitosan was synthesized by adding glutaraldehyde (KG), while bentonite-chitosan modified composites were synthesized by adding bentonite to modified chitosan (KKGB). The investigated aspects consist of effect of contact time, adsorbent dosage, and initial concentration of dye solution. The mechanism of the adsorption process was evaluated using isotherm and kinetic models. The resultsof this study indicated that the increase in efficiency of color removal and the decrease of adsorption capacity of KGand KKGB was found at higher adsorbent dosage and lower initial dye concentrations. The equilibrium time of DB 14 adsorption on both adsorbents was achieved at 20 minutes. The optimum adsorbent dosage for KG and KKGB were achieved at dosage of 1.0 g/L and 1.4 g/L, with dyes removal of 91,6% and 91,8% respectively. The adsorption kinetic of DB 14 onto KG and KKGB fitted well with the pseudo second order model with K 2 of 0.060 g.g -1 . min -1 and R 2 0.999 for KG and K 2 of 0.081 g.g -1 . min -1 and R 2 0.999 for KKGB. The adsorption equillibrium data of DB 14 on KG was well described by Langmuir isotherm model with K L 8.482 L/mg and K F 7.157 mg/g and R 2 0.999 whereas KKGB was well described by Freundlich isotherm model with R 2 0.999 .

The textile industry in its manufacturing process requires large amounts of water where approximately 70% of the process water will turn into wastewater. Textile industrial wastewater is known to contain color compounds which are difficult to degrade, which can cause aesthetic value problems in air receiving bodies, are biohazardous and contain toxic and carcinogenic materials that can harm the health of humans and other living things. Most of the textile industries in the Bandung area discharge their wastewater into the Upper Citarum River containing dyes in the form of azo dyes. One of the advanced wastewater treatment technologies for color removal is the Advanced Oxidation Process (AOP) with ozone (O3) which is capable of decolorizing textile wastewater. The ozonation process was carried out in a reactor with a volume of 16 L in batches on Reactive Black 5 (RB5), Reactive Yellow (RY), and Reactive Blue (RB) dyes with various concentrations of 5 mg/L, 10 mg/L, 15 mg/L respectively and variations in ozone doses of 7.44 mg/minute and 22.32 mg/minute. Decolorization of RB5, RY, and RB at various concentrations of 5 mg/L and 10 mg/L reached 100% at an ozone dose of 22.32 mg/minute. Decolorization at various color concentrations of 15 mg/L with variations in ozone doses of 22.32 mg/minute for RB5 was 99.77% while RY and RB reached 100%. The measured low dissolved ozone concentration results indicate that ozone has reacted and oxidized the organic compounds contained in the wastewater. The highest organic compounds removal was obtained in reactor with variation in ozone doses of 22.32 mg/minute, which reached 100%. The best results of the azo dye decolorization experiment were RB>RY>RB5, respectively.
