This study aims to examine the relationship between curriculum quality, educational facilities, and time management on student satisfaction in the learning process at High Schools. Using a quantitative approach with a stratified random sampling technique, the study involved 250 students from various High Schools. Data were collected using a structured questionnaire and analyzed through multiple linear regression with the help of SPSS software. The results showed that all three independent variables—curriculum quality, educational facilities, and time management—have a simultaneous and significant influence on student satisfaction. Among the three, curriculum quality has the most dominant effect, followed by educational facilities and time management. The coefficient of determination (R²) indicated that 37.7% of the variance in student satisfaction can be explained by the three variables. These findings highlight the importance of a relevant and flexible curriculum, adequate school facilities, and effective learning time management in improving students' learning experience.

Tax avoidance is an activity that minimizes tax funds incurred by a company. This activity is legally effective, but goes against the government's efforts to increase state tax revenues. One of the tax avoidance practices that businesses can do is to implement external funds through debt costs. Debt costs are the rate of return arising from the company's debt transactions to external parties. This study attempts to determine the relationship between tax avoidance and debt costs in mining companies in 2021-2024. The data from this study use secondary data obtained from the Indonesia Stock Exchange for the period 2021–2024. The total sample used in this study was 84 samples. Sampling using purposive sampling technique. Data analysis using simple linear regression analysis using the SPSS 25 program. The results of the study indicate that the Tax avoidance variable has no effect on debt costs.

This study entitled the effect of work motivation on employee performance (empirical study of CV. Ayna Factory Sumedang and CV. Seven Brave Sumedang). The problem of these two companies is the lack of optimization in improving employee performance. This study aims to determine the effect of work motivation on employee performance at CV. Ayna Factory Sumedang and the effect of work motivation on employee performance at CV. Seven Brave Sumedang. This study uses quantitative methods with a survey approach, documentation, data collection techniques, namely by observation and questionnaires. Sampling was carried out by saturated sampling with a total of 54 respondents from CV. Ayna Factory Sumedang and 44 respondents from CV. Seven Brave Sumedang. The data analysis technique uses simple linear regression analysis, correlation test, correlation coefficient, determination coefficient and t test with data processing using the Statistical Product and Service Solution (SPSS) version 25. The results of the discussion of the coefficient of determination test (R Square) show that the effect of work motivation on employee performance at CV. Ayna Factory Sumedang of 67.9% and the influence of work motivation on employee performance at CV. Seven Brave Sumedang is 23.7%, and the rest is influenced by other factors such as leadership, awards, structure, job design, resources, work environment, and others that are not discussed in this study. The results of the t test show that work motivation has a positive and significant effect on employee performance at CV. Ayna Factory Sumedang. And also work motivation has a positive and significant effect on employee performance at CV. Seven Brave Sumedang

Kemajuan teknologi menuntut siswa memiliki keterampilan berpikir komputasional sekaligus karakter yang kuat. Namun, belum tersedia model pembelajaran yang mengintegrasikan kedua aspek tersebut secara simultan. Penelitian ini bertujuan melakukan analisis kebutuhan untuk mengembangkan model pembelajaran DELPHI-STEAM (Deep Learning Project Hypnoteaching-STEAM) berbasis Learning Management System (LMS). Menggunakan model pengembangan ADDIE, penelitian saat ini berada pada fase analisis. Data dikumpulkan melalui instrumen penilaian berpikir komputasional, survei karakter, protokol observasi, dan wawancara terhadap guru serta siswa di 15 sekolah negeri dan swasta di Kabupaten Sumedang. Hasil penelitian menunjukkan bahwa pengembangan model DELPHI-STEAM berbasis LMS beserta perangkat pendukungnya sangat esensial dan layak diimplementasikan. Model ini terbukti dapat meningkatkan kemampuan berpikir komputasional dan pengembangan karakter secara bersamaan. Selain itu, model ini mampu mentransformasi matematika dalam proyek STEAM menjadi pengalaman belajar yang lebih bermakna dan menyenangkan bagi siswa. Technological advancements demand that students possess both computational thinking skills and strong character development. Currently, pedagogical models that simultaneously integrate these two aspects remain scarce. This study aims to conduct a needs analysis for developing the LMS-supported DELPHI-STEAM (Deep Learning Project Hypnoteaching-STEAM) model. Adopting the ADDIE development framework, the research is currently in the analysis phase. Data were collected through computational thinking assessments, character surveys, observation protocols, and interviews involving teachers and students across 15 public and private schools in Sumedang Regency. The findings indicate that the development of the LMS-based DELPHI-STEAM model and its supporting tools is both essential and feasible. This model is designed to concurrently enhance computational thinking and character growth. Furthermore, it transforms mathematics, traditionally utilized as a mere computational tool in STEAM projects, into a more meaningful and engaging learning experience for students.
