Abstract

This study aims to investigate the impact of STEM-integrated Project-Based Learning (PjBL) on Grade 10 students' creative thinking skills. A quasi-experimental method with a non-equivalent control group design was employed. The research population comprised 324 Grade 10 students at SMA Negeri 1 Lingsar during the 2025/2026 academic year. Using a purposive sampling technique, two classes were selected: Class X8 (n=36) as the experimental group and Class X2 (n=36) as the control group. The experimental group was treated with the STEM-PjBL model, while the control group followed a conventional learning model. Data were collected using an instrument consisting of seven essay items focused on renewable energy topics. The results indicated that the experimental group achieved a higher average score (74.31), categorized as "creative," compared to the control group (66.19), categorized as "moderate." Hypothesis testing using a pooled variance t-test yielded tcount = 2.44, exceeding the ttable value of 1.99 at a 5% significance level. Consequently, Ha was accepted, confirming that the STEM-integrated Project-Based Learning model significantly enhances students' creative thinking skills in physics.

Abstract

This study examines the communication styles of female leaders in a local print media company, the Metropolitan Daily, in Bogor, which is transforming along with current digital developments. Leadership is a fundamental element in organizations, and effective communication is key to success, especially for female leaders. This study examines the leadership communication style of the Metropolitan Daily Production Manager, Febriula Sindisari. This study uses a descriptive qualitative method with a case study approach. The purpose of the study is to identify the communication styles of female leaders in the media company and the interpersonal interactions between female leaders and employees. The main theories used are leadership communication theory and gender communication theory. The results show that Sindisari's communication style tends to be equalitarian, flexible, situational, and familial, prioritizing discussion and deliberation in decision-making. The communication flow is vertical (top-down and bottom-up) and horizontal, often utilizing informal channels to absorb staff aspirations. Sindisari's leadership style is transformational and participatory, encouraging collaboration, empathy, and objectivity in problem-solving. Subordinate perceptions indicate clear communication and openness to input. Female leaders in the media industry have the potential to be agents of change in facing the challenges of the digital era.
