This study aims to determine the application of the entrepreneurship-based Project-Based Learning (PjBL) model to improve students' critical thinking and collaboration skills in Biology lessons at MAN 2 Tanjung Jabung Timur. This study used the Classroom Action Research (CAR) method, implemented in two cycles: Cycle I and Cycle II. Each cycle consisted of planning, implementation, observation, and reflection. Data collection techniques included observation, assessment, evaluation, reflection, and observation sheets for students' critical thinking and collaboration skills. The results showed that the implementation of the entrepreneurship-based PjBL model improved student learning outcomes, critical thinking skills, and collaboration. Assessment scores increased from 62 in Cycle I to 83 in Cycle II, representing a 33.87% increase. Evaluation scores increased from 73 to 93, representing a 27.40% increase, while reflection scores increased from 76 to 91, representing a 19.74% increase. Students' critical thinking skills also improved in the focus, reason, inference, situation, clarity, and overview indicators, which were dominated by categories 3 and 4 in Cycle II. Furthermore, students' collaborative skills improved across indicators of shared understanding, taking appropriate action, and team regulation. Based on the research results, it can be concluded that the implementation of the entrepreneurship-based Project-Based Learning (PjBL) model is effective in improving students' critical thinking and collaboration skills in Biology.

At SMP Negeri 2 Gucialit, teachers have difficulty designing and implementing learning models that can develop students to have skills in critical thinking and problem solving, creative thinking skills, communication skills, and collaboration skills. The aim of this community service is to expand understanding of concepts and improve the skills of Junior High School teachers in designing project-based learning through lesson study. The method used in community service consists of three stages, namely preparation, implementation and evaluation. In the preparation stage, field survey activities and coordination with service partners were carried out. At the implementation stage, material is provided, practice is carried out in developing project-based learning teaching modules through lesson study and discussion. At the evaluation stage, an assessment of the results of the activities was carried out using a questionnaire distributed to participants by the community service team. Based on the results of the questionnaire, it shows that the percentage of answers achieved was 59.3% strongly agree with the benefits of this activity, 37% agree, 3.7% neutral, and there were no answers strongly disagree or disagree. This shows that this service activity increases the understanding of the concepts and skills of Junior High School teachers in designing project-based learning through lesson study. Apart from that, this community service activity produces project-based learning teaching module products and aquascape learning media.

Development Module is the process of creating or refining an educational module. This module can consist of lesson materials, study guides, or learning packages designed to achieve specific learning objectives. A good learning module is usually organized systematically, refers to competency standards, and uses various engaging learning media. This research uses the Research and Development (R&D) method conducted at SMA Darun Najah.The purpose of the research is to increase students' interest in learning. The research results show that the PjBL-based module can enhance students' interest in learning. This was determined by giving a questionnaire to students containing several questions, and the students' responses indicated that the module could boost their enthusiasm for learning.
