Biology learning in Indonesia is still predominantly teacher-centered, limiting students’ opportunities to actively develop critical thinking, creativity, collaboration, and other 21st-century competencies. Students often receive information passively, resulting in low engagement and limited ability to apply concepts in real-life contexts. Therefore, innovative learning models are needed to support more meaningful and student-centered learning. This study aims to review the implementation of Project-Based Learning (PjBL) in Biology education and analyze its contribution to the development of students’ 21st-century skills. The study employed a literature review method by analyzing 20 research articles published between 2022 and 2026. Articles were obtained through Google Scholar searches and selected based on relevance to Biology education, focus on PjBL implementation, and open-access availability. Data collection involved identification, screening, selection, and documentation of related studies, while data analysis used a qualitative descriptive approach. The findings indicate that PjBL effectively improves students’ cognitive achievement, conceptual understanding, scientific literacy, creativity, and critical thinking skills. In addition, PjBL enhances collaboration, communication, problem-solving abilities, learning motivation, and life skills through contextual and authentic project activities. Students become more actively involved in investigating real-world problems, designing solutions, and producing meaningful learning outputs. Furthermore, the integration of STEM approaches, digital media, blended learning, and Culturally Responsive Teaching (CRT) strengthens the effectiveness of PjBL in Biology learning. Overall, PjBL is highly relevant for supporting the Merdeka Curriculum and improving the quality of Biology education in developing 21st-century competencies.

Human resources are the most important asset in an organization/business, especially in an educational institution, so they are very important. It is important that existing human resources can be planned as well as possible to achieve the goals of the organization/institution. Careful human resource planning will ensure smooth operations. Yes or no, this is the operational process of an organization/institution. There are many effective and efficient human resource planning models, but effective human resource planning and effective intentions are sometimes not realized optimally, only limited to imagination and desire. just a hope. Therefore, this research was conducted to analyze human resource planning and find solutions to problems that influence HR planning at Mis Al-Washliyah Greahan. The research method used by researchers in this research is a qualitative approach with descriptive methods using interview techniques, observation and document study. After the data is collected, classify, edit and present the data based on each data type. Before data is collected, it is first analyzed and checked for validity. The research results show that human resource planning is carried out through programs, activities, planning stages, including quality indicators or goals to be achieved in a process of improving the quality of education. This form of planning includes resource management which includes developing human resources, developing the learning process and increasing the capacity of human resources to improve the quality of education.

The problem in this research is the lack of variation in learning carried out by teachers in the classroom, due to the inappropriate selection of learning models, so that learning is less than optimal. The aim is to evaluate how effective the Discovery Learning learning model is in increasing student understanding compared to conventional learning methods. The method used is an experiment with a quasi-experimental design, namely Nonequivalent Control Group Design. In this study, there were two groups: an experimental group that was taught using Discovery Learning and a control group that was not given this treatment. The population of this study were all 5th grade students at MIN 1 Soppeng. The research hypothesis analyzed using the T test is the statement that the Discovery Learning learning model influences student learning outcomes. The sample in this study was determined by a saturated population, namely 5th grade students consisting of 45 people. The data collection techniques used in this research were multiple choice tests and observation sheets, with pre-tests and post-tests to measure students' cognitive learning outcomes. The instruments used in this research were tests and non-tests. The average pretest score in the experimental class and control class was almost the same, 71.78 and 71 respectively, but in the posttest, the experimental class increased to 88.65, while the control class only reached 77.55. Thus, the experimental class experienced a more significant increase in the average posttest score compared to the control class, indicating that the intervention or treatment applied in the experimental class was more effective in improving student learning outcomes. Hypothesis testing based on t-test analysis shows significant differences between the two groups, where the calculated t value (11.22771) is greater than the t table (2.016692), so the null hypothesis (H_0) is rejected and the alternative hypothesis (H_1) is accepted. These findings show that the Discovery Learning learning model has a greater positive impact on improving student learning outcomes compared to conventional methods, so it can be concluded that this method is effectively used in science learning at MIN 1 Soppeng.
