Abstract

Until now, the application of a combination of biological, physical, and chemical methods to eliminate contaminants from the rubber industry wastewater has not been reported. The purpose of our investigation is to analyze the use of membrane techniques and the effect of pre-treatment of industrial rubber wastewater—pre-treatment by ozone on the performance of the modified PES-nano ZnO membrane. Modified PES-nano ZnO membranes were made with phase inversion techniques and membrane performance based on flux and rejection. Filtration processes with cross-flow filtration systems and ozonation time variations were 1, 2, 3 hours. The ozonation process influenced membrane rejection. The membrane rejection value increased to 89.6%, and ammonia decreased to 4.3 mg/L. The flux value increased to 10.2 L.M-2.h-1 in 1h Ozonatian and decreased with the increasing of filtration time. Pre-treatment with ozonation can increase membrane selectivity and extend membrane life during the filtration process due to reduced fouling. The pre-treatment process time with 3 hours-ozonation was the most violent rejection even though the flux value has decreased

Abstract

Agam district has a coconut plantation of 56,744 hectares with an average production of 3,000 tons per year. Coconut water is one of the coconut plant products that has not been utilized optimally. Many benefits or new products that have a higher selling value use coconut water as a raw material. One of the products derived from coconut water that we consume daily is Nata de coco. Nata de coco has high fiber, but low in calories. Nata de coco can also be a business opportunity for the home industry. Based on the business opportunity from Nata de coco, The community service of Politeknik ATI Padang held the training of the production of Nata de coco to the women community in Kamang Hilir Village, Agam District, West Sumatera. The training was carried out on February 5, 2023 attended by 30 participants. The training began with the explanation about the materials and tools used in making Nata de coco. The main materials used were coconut water, urea, sugar, Acetobacter xylinum. Then, the practice is carried out jointly between the women community and the community service team from Politeknik ATI Padang. The training was closed with the presentation of business prospective from Nata de coco. All of the participants were enthusiastic with this training. It is expected that the women community in Kamang Hilir Village have the knowledge and the skill to make their own Nata de coco.
