This study aims to synthesize a zinc crosslinked chitosan (Chi/Zn) membrane as an adsorbent for amoxicillin in pharmaceutical wastewater. The Chi/Zn membranes were prepared over 14 hours at 50 °C with varying chitosan and zinc concentrations. FTIR analysis confirmed successful crosslinking by identifying hydroxyl (O-H), carbonyl (C-O), and amine groups (NH2), along with N-Zn and O-Zn interactions. XRD analysis indicated an amorphous structure, while SEM revealed rough, uneven surfaces. The highest adsorption capacity of a chitosan membrane occurs at a concentration of 60 mg/L. At this concentration, the pure chitosan membrane's adsorption effectiveness and capacity are 42.2% and 42.2 mg/L, respectively. The Chi/Zn membrane adsorbed amoxicillin with an adsorption efficiency of 58.86% with an adsorption capacity of 58.86 mg/g. Thus, it can be said that the chitosan/Zn membrane is quite effective in being applied as an amoxicillin adsorbent in pharmaceutical waste. © 2024, Rasayan Journ.....

Football is a popular community sport that provides numerous benefits, including the development of physical, mental, and social skills. In this context, the first touch technique is critical because it influences the player's ability to control the ball and determine the direction of the attack. However, many young players at the Tarogong Kidul club, particularly at SSB Anpal FC, are less effective at first touch due to a lack of use of modern training methods. The goal of this study is to determine the impact of the first touch training program on the fundamental techniques of the first touch, as well as the impact of the first touch training program on the player's com-petitive playing abilities. The method used in this study is quantitative (experimental), with a pre-experiment and one group pretest-posttest as the research design. The results showed that the first touch training program significantly improved players' technical skills and playing performance, with an average incre.....

Background. The development path of a football player toward becoming a professional player involves four main aspects: physical, technical, tactical, and psychological ones. Objectives. This study aimed to examine the psychological characteristics of the environment that influence and contribute to the development of football players under 17 years old in Indonesia and Malaysia. Materials and methods. This study used a qualitative approach, namely evolved grounded theory, and the data collection process was conducted using three distinct methods: semi-structured interviews, observation, and document analysis. Twenty-five coaches participated in this study, comprising fifteen coaches from various football academies in Malaysia and ten coaches from Indonesia. All coaches involved in this study have a license and at least five years of experience as coaches under 17. The data collected and analyzed began with open coding, axial coding, and selective coding, and the analysis was assisted .....

Mathematics is fundamental in the educational system, yet many pupils lack the required skills in the subject. Intervention is crucial for pupils with dyscalculia symptoms. This study evaluates the effectiveness of the Basic Arithmetic Skills (BAS) Module among pupils with dyscalculia symptoms. This is a quantitative study with a quasi-experimental design. One hundred twenty pupils aged between 7 and 14 years, who exhibited dyscalculia symptoms were involved in this study. They were divided into two (2) groups: the control group with 59 pupils and the treatment group with 61 pupils. The results showed that the BAS Module significantly improved the basic arithmetic skills among pupils with dyscalculia symptoms regardless of gender and age. In conclusion, the BAS Module effectively improved the basic arithmetic skills among pupils with dyscalculia symptoms in primary schools. The study emphasizes the importance of tailored instructional materials and the role of teachers in delivering in.....

This research aims to develop a tool for measuring catching-throwing skills using modern, effective, and efficient sensor technology. This tool is designed to increase accuracy in measuring catch-throwing skills. This type of research uses (R&D). This research involved three experts in their field: an electrical expert, an evaluation and measurement expert, and a physicist. A total of 30 participants participated in testing in a small group of 12 people and a large group of 18 people with an age range of 15-20 years. Testing is carried out with questionnaires and direct tests. The statistical analysis used is r-correlation with the help of the SPSS application. The test results show a high alpha coefficient, confirming that this tool is consistent and reliable in collecting data. Three experts carried out practicality testing: Electrical Experts, Evaluation and Measurement Experts, and Physicists. The results show that this tool is efficient, with practicality levels of 98%, 92%, and 8.....

The focus of this work is to establish a hydrometallurgical technique for efficiently extracting gold from the aggregated gold-rich concentrate produced by a mining facility in one of Kazakhstan's deposits. The leaching techniques applied to gravity-flotation concentrates include hydrometallurgical gold recovery processes using the surfactant sulfanol and the oxidizing reagent trichloroisocyanuric acid (TCCA). The findings indicate the effectiveness of leaching gravity-flotation concentrates with oxidizing (accelerating) reagents. Gold extraction through cyanidation of the blended concentrate, ground to 89–90% passing 10 µm with TCCA, averaged 84.0%, compared to 65.76–67.8% with conventional direct cyanidation. The advantage of employing chlorine-based oxidants, such as TCCA, in hydrometallurgical processing lies in their applicability in both acidic and alkaline environments, whereas other oxidants are constrained by specific technological conditions. Technical trichloroisocyanu.....

Bananas serve as a nutrient-rich energy source for human diets, and a valuable raw material for downstream products. Despite the high demand for bananas, they have a relatively short shelf-life. To mitigate these shortcomings, researchers have explored the use of edible coatings to extend the shelf-life of bananas. Nevertheless, only a few studies have assessed the integration of starch, gum, and zinc oxide nanoparticles (ZnONPs) in developing a coating solution that can preserve the qualities of bananas post-harvest. Therefore, the present work assessed the antibacterial properties of a novel edible coating formulation combining cassava starch, xanthan gum, and ZnONPs, and its impact on the physicochemical characteristics and shelf-life of bananas of the ‘Pisang Berangan’ variety (Musa acuminata). Firstly, coating solutions with compositions of cassava starch, xanthan gum, and varying concentrations of ZnONPs were prepared. Their antibacterial properties were then assessed using t.....

Background: Plagiarism is a serious academic misconduct demanding mitigation to uphold the integrity of original work. Undeniably, with the advancement of technological age, plagiarising becomes easier and harder to detect. However, the reliance on technology significantly rises the likelihood of fostering academic dishonesty among the students. Therefore, it is imperative to disseminate explicit education on plagiarism reduction strategies, particularly on the importance of mastering correct referencing techniques. Purpose: The present study applied a mixed-method approach to explore the effectiveness of an intervention called Educational Intervention (EI) on enhancing ESL students’ academic referencing skills namely in in-text citation abilities, paraphrasing skills and writing reference list using APA style. Method: The EI consisted of explicit instruction that involved structured teaching sessions integrated with two primary instructional strategies: lectures and practical exerci.....
