Since the launch of the “Bilingual Policy for all schools supported by Yayasan Pendidikan Katolik (YPK) Don Bosco KAM in 2030,” schools have debated its impact. Teachers of non-English subject express concern about adapting, while parents fear their children may struggle with bilingual instruction. This study investigates how students, teachers, parents, and staff at Private Senior High School of Santo Yoseph Medan perceive the Bilingual education policy decided by YPK Don Bosco KAM in 2030. The research explores key concerns: the necessity of the policy, its effect on local languages, feasibility by 2030, budget sufficiency, availability of qualified teachers, and whether non-English subject teachers can teach bilingually. A questionnaire with seven questions was distributed to 40 participants in Indonesian and later translated into English. Results show 60% believe bilingual education is essential, 10% disagree, 25% are uncertain, and 5% have no opinion. While over half support the policy, challenges remain, including limited funding, a shortage of trained bilingual teachers, and the need for more English classes and learning materials. Successful implementation requires the Don Bosco Catholic Education Foundation to increase funding and address these challenges to ensure smooth integration of bilingual education by 2030.

Stunting remains one of the major public health issues at the national level in Indonesia. As an archipelagic country, Indonesia faces unique challenges in tackling stunting, particularly in regions with limited access to healthcare services. Advances in information technology offer new opportunities to support stunting prevention efforts, including through the utilization of health data. Such data can be used to detect stunting risks early and to monitor children's nutritional status more effectively. The use of health data applications or systems by Posyandu cadres is influenced by various factors, including availability of time, cost, level of trust, and perceptions of ease of use and usefulness. This study aims to identify the determinants of health data utilization by Posyandu cadres for toddlers as a stunting prevention effort in Geneng Subdistrict, Ngawi Regency. This research is an analytical quantitative study with a cross-sectional approach. A sample of 80 Posyandu cadres for toddlers in Geneng Subdistrict was selected using purposive sampling. Data were collected through questionnaires and analyzed using univariate, bivariate, and multivariate logistic regression tests to identify the factors influencing the use of health data in stunting prevention. The results show that the significant determinants include the age of the Posyandu cadre, their education level, and the amount of time they dedicate to Posyandu activities. The determinants of age, education level, and time significantly influence the utilization of health data and thereby affect the optimization of stunting prevention. Strengthening cadre capacity in these aspects is necessary to support more effective stunting prevention.

Stroke is one of the leading causes of death globally and is particularly prevalent in Indonesia. Early prediction of stroke is critical to reducing the risk of long-term disability and mortality. This study aims to build a stroke prediction model using the Support Vector Machine (SVM) classification method. The dataset used is sourced from Kaggle, containing 5,110 records with class imbalance. To address the imbalance, the Synthetic Minority Over-sampling Technique (SMOTE) was applied during preprocessing. The study evaluates model performance across multiple data splits (70:30, 80:20, 90:10) and k-fold cross-validation values (k=5, 7, 10). The SVM was tested with various kernel types—linear, polynomial, and radial basis function (RBF)—along with parameter tuning for C, gamma, and degree. The results show that the polynomial kernel yielded the highest prediction accuracy of 92%. The model performance was evaluated using accuracy, precision, recall, and F1-score metrics.

This study aims to improve the learning outcomes of seventh grade students on the material of Linear Equation One Variable (PLSV) and Linear Inequality One Variable (PtSLV) through the application of the Problem Based Learning (PBL) learning model. This research is a Classroom Action Research (PTK) conducted in two cycles at Bustanul Ulum Pakusari Islamic Junior High School. Each cycle consists of planning, action, observation, and reflection stages. The results showed that in cycle I the average score of students was 69.3 with a completeness rate of 69%, while in cycle II there was an increase in the average score to 74.3 with a completeness rate of 74%. In addition, the activeness of students in the learning process increased from 76% in cycle I to 100% in cycle II. The application of the PBL model is able to increase the active involvement and learning motivation of female students, and has a positive impact on improving learning outcomes. Thus, the application of the PBL model is effective in improving the quality of mathematics learning, especially in PLSV and PtSLV material.

The high level of turnover intention in frontliner employees is a serious challenge for retail companies, including CV. Premium Indonesia. This study aims to analyze the effect of transactional leadership on turnover intention mediated by organizational commitment. This research uses a quantitative approach with survey techniques on 56 frontliner respondents. The results showed that transactional leadership has a negative influence on turnover intention. This means that the more effective the application of transactional leadership style, the lower the employee's intention to leave the company. In addition, organizational commitment also negatively affects turnover intention and is proven to be able to mediate the relationship between transactional leadership and turnover intention. These findings confirm the important role of leadership and commitment in retaining the workforce, especially in the dynamic and competitive retail sector.

Traditional medicine has been believed for generations to be effective in treating various diseases and is recognized for its safety. One reason people opt for herbal medicine is its affordability compared to chemical drugs. Additionally, herbal medicine is required to be free of medicinal chemicals (BKO). However, a public warning issued between 2020 and 2025 indicated that some herbal preparations still contained substances like sildenafil citrate and caffeine. The aim of this research is to establish a validated analytical method to detect the presence of sildenafil citrate and caffeine in stamina-enhancing herbal medicines using Thin Layer Chromatography (TLC) with densitometry. This method was selected due to its cost-effectiveness and its ability to separate two compounds. In this study, category II validation was conducted to identify impurities in the preparations, focusing on test parameters such as selectivity and Limit of Detection (LOD). The selected mobile phase for this study was a mixture of chloroform and ethanol (9.5:0.5 v/v). The TLC plate was analyzed with a densitometer at a wavelength of 254 nm. The Rf value for sildenafil citrate was found to be 0.32, while the Rf value for caffeine was 0.52, resulting in a separation (Rs) value of 2. The LOD for sildenafil citrate was determined to be 8.5418 ?l/ml (equivalent to 0.0854 mg in a 600 mg sample), whereas the LOD for caffeine was 4.7987 ?l/ml (or 0.0959 mg in a 600 mg sample).

This research examines the relationship between stock returns and the financial performance of State-Owned Enterprises (BUMN) listed on the Indonesia Stock Exchange (IDX) before, during, and after the Covid-19 epidemic (2018–2019, 2020–2021, and 2022–2023). Financial performance indicators are the return on invested capital (ROIC), earnings per share (EPS), working capital turnover, total asset turnover, cash ratio, debt-to-equity Ratio, debt-to-asset Ratio, Current Ratio, and cash ratio. The study's primary sources are BUMN's annual financial reports and stock price data. A multiple linear regression model examined the connection between stock returns and financial performance. According to the findings, the variables influencing stock returns varied throughout time. Before the pandemic, cash ratio and earnings per share (EPS) significantly enhanced stock returns, reflecting investor attention to liquidity and profitability during economic stability. During the pandemic, total asset turnover emerged as the key variable impacting stock returns, emphasizing the necessity for efficient asset management amidst economic uncertainty. After the pandemic, earnings per share (EPS) and return on invested capital (ROIC) became the most influential factors, indicating investors' focus on profitability and the ability to generate investment returns. The study concludes that the COVID-19 epidemic has significantly impacted the correlation between stock returns and financial performance. These results provide corporate management and investors with important information for creating flexible financial plans that adjust to shifting market conditions.
