Abstract

Biology education requires a learning strategy that can improve conceptual understanding while developing students' critical thinking skills. This study aims to analyze the influence of the Project-Based Learning (PjBL) learning model on the learning outcomes of class X students on biodiversity materials at SMA Negeri 1 Melonguane. The research uses a quasi-experimental method with a Pretest-Posttest Control Group Design, involving two classes, namely the X-A experimental class taught using the PjBL model with a mini ecosystem project, and the X-D control class. The control class is taught conventionally. The analysis results showed a significant increase in the posttest score of the experimental class with an average of 79.33 compared to the control class with an average of 73.39. These findings indicate that applying the PjBL model effectively creates active learning, increases student engagement, and develops problem-solving skills and creativity. The lower variability of scores in the experimental class showed that PjBL could accommodate differences in students' abilities. Project-based learning also arouses students' motivation and confidence, making Biology learning more contextual and meaningful. The implications of this study show that applying the PjBL model can be an alternative to Biology learning strategies to improve learning outcomes while supporting the development of 21st century skills. This research enriches the literature on Biology learning innovations. It opens opportunities for further studies related to the application of PjBL to other materials or long-term impact analysis on students' academic achievements.

Abstract

Payangka fish (Ophieleotris aporos) is a fish that lives in freshwater and has the ability to survive in the midst of competition with other fishes that are very tough. This study aims to analyze the structure of payangka fish and the growth pattern of payangka fish in Lake Limboto. Fish samples were caught using a 2 cm net with a net length of 7 m and then a 1 m serok (sibusibu) with a total sample of 1003 fish. The results of the length structure analysis of payangka fish obtained a length range of 9.15 - 19.05cm with an average of 12.45 cm and the results of the weight structure analysis obtained a range of 9.27 - 47.97 grams with an average of 13.57 grams. The results of the analysis of the relationship between length and weight of payangka fish obtained allometric growth pattern (b = 2.92), b < 3 which means that weight gain is faster than length gain..

Abstract

Dalam meningkatkan hasil belajar siswa, perlu diperkenalkan keberagaman yang lebih besar dalam pemanfaatan model dan proses pembelajaran yang tidak hanya berorientasi pada Guru. Tujuan penelitian ini adalah untuk mengetahui pengaruh model pembelajaran berbasis proyek (PjBL) terhadap hasil belajar siswa pada materi keanekaragaman hayati di kelas X di SMA Negeri 1 Motoling. Tujuan penelitian ini adalah untuk mengetahui apakah model project-based learning (PjBL) dapat meningkatkan hasil belajar siswa pada materi keanekaragaman hayati pada siswa kelas X SMA Negeri 1 Motoling. Penelitian dilaksanakan di SMA Negeri 1 Motoling pada bulan Maret 2024 dengan menggunakan pendekatan eksperimen semu. Penelitian difokuskan pada kelas X-A sebagai kelompok eksperimen dan kelas X-C sebagai kelompok kontrol. Kedua kelas akan menjalani penilaian hasil belajar berupa pre-test dan post-test. Hasil analisis data menunjukkan bahwa model pembelajaran berbasis proyek (PjBL) mempunyai pengaruh yang signifikan terhadap hasil belajar siswa pada materi keanekaragaman hayati di kelas X SMA Negeri 1 Motoling. Jika nilai signifikansi dua sisi (Sig.) yang diperoleh dari analisis uji-t menggunakan IBM SPSS for Windows lebih kecil dari tingkat alpha penelitian yang telah ditentukan yaitu 0,05, khususnya bila nilainya 0,00 yaitu kurang dari 0,05, maka hipotesis nol (H0) ditolak dan hipotesis alternatif (H1) diterima. Hal ini menunjukkan dampak penggunaan model pembelajaran project-based learning (PjBL) terhadap peningkatan hasil belajar siswa pada mata pelajaran keanekaragaman hayati kelas X di SMA Negeri 1 Motoling.

Abstract

Penelitian ini bertujuan untuk menghasilkan multimedia interaktif yang menggunakan PowerPoint (PPT), materi pertumbuhan dan perkembangan pada tumbuhan. Pengembangan multimedia pembelajaran dilakukan untuk meningkatkan minat belajar, meningkatkan pemahaman, dan membantu siswa menjadi lebih termotivasi untuk belajar. Penelitian ini dilaksanakan Di SMA Negeri 2 Tondano tahun ajaran 2024. Untuk mengembangkan multimedia interaktif peneliti menggunakan pengembangan Model Analysis Design Development Implementation and Evaluation (ADDIE). Alat yang digunakan untuk mengumpulkan data adalah Lembar validasi, Kuisioner atau angket. Dalam penelitian ini peneliti juga menggunakan lembar angket validasi sebagai penilaian subjek untuk mengetahui kelayakan kedua validator: validasi ahli materi, dan validasi ahli media. Untuk menentukan kelayakan multimedia interaktif yang dikembangkan. Subjek uji coba dalam penelitian yaitu, guru mata pelajaran biologi dan siswa kelas XI B Ruang 1 (R1) berjumlah 19 siswa. Pada hasil penilaian persentase berdasarkan penelitian yang dilakukan terhadap validasi ahli materi memberikan penilaian multimedia pembelajaran 92% kriteria sangat valid, validasi ahli media 95% kriteria sangat valid, dan guru mata pelajaran biologi 97% kriteria sangat valid serta hasil penilaian respons siswa 95% dengan kriteria sangat baik. Sehingga dapat disimpulkan bahwa pengembangan multimedia interaktif menggunakan PPT, yang telah dikembangkan layak untuk digunakan sebagai salah satu bahan ajar media pembelajaran Di SMA Negeri 2 Tondano.

Abstract

This classroom action research was conducted to enhance learning interaction and conceptual understanding among eleventh-grade students through the implementation of a jigsaw cooperative learning model supported by visual media at SMA Negeri 2 Tompaso. The study followed a cyclical research procedure comprising four distinct phases: systematic planning, strategic implementation, structured observation, and critical reflection. The research involved 25 participants from class XI F1 during the odd semester of the 2025/2026 academic year. The findings demonstrated substantial improvement in both student engagement and comprehension between the initial and subsequent cycles. The classical mastery percentage showed remarkable progress, increasing from 40% in Cycle I to 88% in Cycle II. This significant enhancement provides compelling evidence that the jigsaw cooperative learning approach, when effectively integrated with visual media, serves as a powerful pedagogical strategy for improving both interactive learning dynamics and conceptual mastery of human digestive system material among senior high school students. The research outcomes clearly indicate that the synergistic combination of cooperative learning structures and visual media support creates an optimal learning environment that fosters active participation and deepens conceptual understanding in biology education
