The oxygen delignification of pulp process requires proper control of the kappa number, viscosity, and brightness to achieve optimal pulp quality. However, increasing kappa number reduction is often accompanied by a significant decrease in viscosity, thereby reducing oxygen delignification selectivity. Therefore, auxiliary chemicals in the form of surfactants are required to enhance the effecti…
Adolescents are the age group most vulnerable to the consumption of sugar-sweetened beverages compared to other age groups. This study aims to analyze the relationship between knowledge, attitudes, social media exposure, and the role of peers on sugar-sweetened beverage consumption habits among adolescents at State High School 11 in Palembang.

Water pollution caused by copper (Cu²⁺) ions is an environmental problem because these ions are toxic and can accumulate in organisms. One method that can be used to remove heavy metal ions from water is adsorption. This study aims to synthesize and evaluate biopolymer-based hydrogel composites of CMCS/sodium alginate and CMC/CMCS/sodium alginate as Cu²⁺ adsorbents. Chitosan is poorly sol…
