This study aims to analyze the reflection table in the book Wonderful Insight English class VII published by Erlangga in 2023 based on the perspective of Wilhelm Wundt's structuralism psychology. The reflection table contains five main statements, namely Now I know about, I wonder about, It is confirmed that, My misconception so far was that, and I have learnt about, which are designed to help students evaluate their learning experiences. The research uses a descriptive qualitative method with a document analysis approach, and utilizes the concept of introspection and elements of consciousness in Wundt's theory of structuralism. The results of the analysis showed that each statement of reflection represented a different stage of consciousness. Now I know about marking the emergence of new knowledge, I wonder about reflecting curiosity and further thinking process, It is confirmed that it shows the strengthening of the understanding that has been had, My misconception so far was that it reveals awareness of misconceptions, while I have learnt about affirming the final result of learning. These findings confirm that the reflection table in the book has facilitated the process of student introspection, while strengthening learning awareness in line with the principles of structuralism psychology Wilhelm Wundt. Thus, reflection is an important instrument in building students' cognitive awareness in 21st century learning.

Dermatophytosis is a superficial fungal infection of the skin, hair, and nails that is often found in tropical climates such as Indonesia, including Jambi City, which has high humidity and community habits that can support fungal growth. This study aims to describe the demographic characteristics of dermatophytosis patients who received treatment at a private dermatologist and venereologist in Jambi City throughout 2023. This study used a descriptive design using secondary data from patient medical records. A total of 399 patients who met the inclusion criteria were analyzed univariately and the results are presented in the form of a frequency distribution table. The results showed that tinea corporis was the most common type of dermatophytosis, followed by tinea cruris and tinea capitis. The majority of patients were male, aged 17–25 years, had a high school education, and worked as students. The most common locations of lesions were on the trunk and groin. These findings suggest that the productive age group is more susceptible to dermatophytosis, possibly related to high physical activity, excessive sweating, and suboptimal personal hygiene. This research is expected to be the basis for planning health education regarding the prevention of fungal infections and improving clean and healthy living behavior in the community.

Oxytocin massage is a technique used to stimulate the release of the hormone oxytocin, which plays a vital role in breastfeeding. Spinal massage stimulates the parasympathetic nervous system, which then triggers the release of oxytocin. This hormone causes contractions in the muscle cells surrounding the milk ducts, thereby promoting breast milk production. The purpose of this study was to determine the effect of oxytocin massage on increasing breast milk production in postpartum mothers. This study used a quantitative design with a quasi-experimental approach, namely a one-group pretest-posttest design. The study population was postpartum mothers with breast milk flow problems at the Bandarharjo Community Health Center, Semarang City. The sampling technique used was purposive sampling, where researchers selected samples based on certain characteristics. Data collection was carried out using a questionnaire. Data analysis used the Chi-Square test. The results of the study showed that the calculated Chi-Square value on the first day (62,000) was greater than the Chi-Square table (12,591), on the second day (54,866 > 23,684), and the third day (58,117 > 32,670). Based on these results, H0 was rejected and Ha was accepted, which means there was a significant effect of oxytocin massage on the smooth production of breast milk in postpartum mothers at the Bandarharjo Community Health Center.

Digital transformation in Indonesia's financial sector has accelerated the adoption of cashless payment systems, with QRIS (Quick Response Code Indonesian Standard) as the main innovation since its introduction by Bank Indonesia in 2019. Generation Z, as a digital native group, is the dominant user of QRIS due to their preference for fast, practical, and connected services. This study aims to empirically analyze the influence of lifestyle, ease of use, trust, and financial attitudes on the decision to use QRIS by Generation Z in Bogor Regency, as well as test the role of financial literacy as a moderation variable. The research approach uses quantitative methods through inferential statistical analysis. The results showed that only the variables of ease of use and financial attitude had a significant effect on the decision to use QRIS, with a significance value of < 0.05 and t calculated > t table. These findings reinforce the Technology Acceptance Model (TAM) model, which emphasizes the importance of the perception of convenience in driving the adoption of digital payment technology. Meanwhile, the variables of lifestyle and trust did not have a significant effect, which may be due to the level of general trust that has been formed in QRIS and the digital lifestyle of respondents who have not fully developed. These results confirm the need to develop a more intuitive user experience and increase education related to digital financial literacy to strengthen the sustainable use of QRIS among Generation Z.

CPU scheduling is a core function in modern operating systems that significantly impacts system performance and efficiency. Among various scheduling algorithms, Priority Scheduling is widely used and exists in two main variants: non-preemptive and preemptive. The non-preemptive mode allows a process to run to completion, while the preemptive mode can interrupt a running process for a higher-priority one. Understanding the behavioral differences between these modes is crucial but often challenging through manual calculations. To address this, an interactive web-based application was developed to simulate and visualize both preemptive and non-preemptive Priority Scheduling algorithms. The research method involved designing the system logic based on the core principles of each scheduling variant, followed by implementation using standard web technologies: HTML, Tailwind CSS, and JavaScript. The application allows users to input custom process data or load predefined case studies, select the scheduling mode, and instantly receive a comprehensive analysis. The results include a dynamically generated Gantt chart, a detailed performance metrics table (including turnaround time and waiting time), and a step-by-step execution log. Through a comparative analysis of a specific case study, the application is proven to be an effective educational tool. It accurately simulates both modes and visually demonstrates the impact of preemption on execution order, resource utilization, and key performance metrics, thereby simplifying the learning process for students and educators.
