This research aims to create effective biology teaching to improve student learning outcomes and activeness using project-based learning (PjBL). Classroom action research (CAR) was used to create effective learning. A total of 24 students became the subject of this CAR. They are in class XI IPA. Students were observed for three meetings using the observation sheet to measure attitudes, skills, and activity. We were measuring students' cognitive learning outcomes using tests. The CAR results showed that 79.16% of students achieved a minimum standard of 70. A total of 66.67% achieved skills from good to very good. Student activity and teacher activity has increased. This CAR concludes that PjBL effectively improves biology learning and improves students' learning outcomes. Some students have not reached the good category, so further research in the use of PjBL can be improved.

This study aimed to analyze the validity and student responses to the supplement book developed in the animal diversity course based on the identification of fish species caught by fishermen in Warido Amberimasi Village, Biak Numfor Regency. This development research refers to the ADDIE development model; this study is limited to ADD stage. Research subjects include 4th-semester biology education students at the University of Papua. The object of research is a complementary book. The instruments used to assess the validity and practicality of teaching materials include a validity assessment sheet by expert validator one and a validity assessment sheet by expert validator two. Based on the validity of the supplement book with validity criteria with a percentage value of 81.82% (very valid) and the results of student responses to supplement books with an average response value of 86.80% included in the very good category, the supplement book developed can be used as a reference in the student learning process Biology education for 4th-semester students at the University of Papua.
