This study aims to analyze the impact of corporate governance, renewable energy, and waste management on sustainable development goals (SDGs) at PT Rajawali Dwi Putra Indonesia. The three variables were chosen because they are closely related to sustainability activities that have become a global focus, especially in facing environmental, economic, and social challenges. This study uses a quantitative approach with data collection techniques through a 1-5 Likert scale questionnaire distributed to all company employees through the census method. Data analysis was conducted using multiple linear regression which includes validity, reliability, classical assumptions, and hypothesis testing (t test and F test). The results showed that partially, renewable energy and corporate governance have a significant positive effect on development goals. Meanwhile, waste management also has a significant effect yet a negative relationship direction. Simultaneously, the three independent variables have a significant positive effect on sustainable development goals. These findings are expected to be a reference for companies in formulating sustainability strategies and supporting the acceleration of achieving sustainable development goals, especially in developing countries such as Indonesia.

This study aims to determine the effect of obesity education videos on knowledge and attitudes towards obesity and their effectiveness in non health workers at Dr. Sardjito Hospital Yogyakarta. The research method used was quasi experimental with pretest-posttest control group design. The intervention test was carried out by giving obesity education videos to the intervention group. The results showed that there was a significant increase in knowledge in the intervention group after giving obesity educational videos (p = 0.000), while in the control group there was no significant change (p = 0.083). However, in the aspect of attitude, both intervention and control groups did not show significant changes (p> 0.05). This shows that educational videos are effective in increasing knowledge, but do not significantly affect changes in attitudes towards obesity. The conclusion of this study is that educational videos can be used as an effective medium in delivering health information to improve knowledge, but to achieve attitude improvement, comprehensive methods are needed, including social interaction and direct experience
