ABSTRAK
Penelitian ini bertujuan (1) Untuk mengetahui perbedaan pencapaian antara Problem Based Learning (PBL) dan Model Kooperatif tipe Student Team Achievement Division (STAD) terhadap hasil belajar biologi peserta didik  SMA Negeri di Kabupaten Grobogan (2) Untuk mengetahui perbedaan minat belajar tinggi dan minat belajar rendah terhadap pencapaian hasil belajar biologi peserta didik SMA Negeri di Kabupaten Grobogan (3) Untuk mengetahui interaksi model pembelajaran dengan minat belajar peserta didik terhadap pencapaian hasil belajar biologi SMA Negeri di Kabupaten Grobogan.
Penelitian ini dilaksanakan di SMA Negeri di Kabupaten Grobogan. Metode yang digunakan dalam penelitian ini adalah penelitian eksperimen dengan rancangan faktorial 2x2.
Hasil penelitian menunjukkan bahwa (1) Perbedaan Pencapaian Model PBL dengan Model Kooperatif tipe STAD terhadap Hasil Belajar Biologi. Hasil analisis Two-Way Anova menunjukkan terdapat perbedaan yang signifikan hasil belajar Biologi pada kelompok dengan menggunakan model pembelajaran PBL dan kelompok kooperatif tipe STAD, dengan nilai F = 4.669 dengan p < 0,05; dimana hasil belajar peserta didik pada mata pelajaran Biologi dengan model PBL lebih baik daripada peserta didik yang menggunakan model kooperatif tipe STAD (2) Perbedaan Minat Belajar Tinggi dengan Minat belajar Rendah terhadap pencapaian hasil belajar Biologi. Hasil analisis Two-Way Anova menunjukkan terdapat perbedaan yang signifikan hasil belajar Biologi pada kelompok peserta didik dengan minat belajar tinggi dan kelompok peserta didik dengan minat belajar rendah, dengan nilai F = 5.554 dengan p < 0.05; dimana hasil belajar peserta didik pada mata pelajaran Biologi yang memiliki minat belajar tinggi lebih baik daripada peserta didik yang memiliki minat belajar rendah. (3) Interaksi Model pembelajaran dan Minat belajar dalam kaitannya dengan pencapaian hasil belajar Biologi. Hasil perhitungan analisis Two-Way Anova diketahui terdapat interaksi antara model pembelajaran dengan minat belajar terhadap pencapaian hasil belajar Biologi dengan nilai F = 4.434 dengan  p <0.05 ; dimana nilai rata-rata hasil belajar Biologi pada kelompok model PBL dengan minat belajar tinggi mempunyai nilai rata-rata tertinggi sebesar 83.88 sedangkan kelompok model PBL dengan minat belajar rendah mempunyai nilai rata-rata terendah sebesar 74.47.

ABSTRACT
The objectives of this research are to investigate: (1) the difference of effect between the PBL model and the cooperative learning model of the STAD type on the Biology learning outcome of the students of Senior Secondary Schools of Grobogan Regency; (2) the difference of effect between the high learning interest and the low learning interest on the Biology learning outcome of the students of Senior Secondary Schools of Grobogan Regency; (3) and the interaction of effect between the learning models and the learning interests on the Biology learning outcome of the students of Senior Secondary Schools of Grobogan Regency.
This research used the experimental research method with the factorial design of 2x2. It was conducted at Senior Secondary Schools of Grobogan Regency.
The results of this research are as follows: (1) there was a significantdifference of effect between the PBL model and the cooperative learning model of the STAD type on the Biology learning outcome of the students of Senior Secondary Schools of Grobogan Regency where the former had a better effect on the Biology learning outcome than the latter as indicated by the result of the two-way analysis of variance (ANOVA) in which the F-value was 4.669 and the p-value was smaller than 0.05; (2) there was a significant difference of effect between the high learning interest and the low learning interest on the Biology learning outcome of the students of Senior Secondary Schools of Grobogan Regency where the former had a better effect on the Biology learning outcome than the latter as indicated by the result of the two-way analysis of variance (ANOVA) in which the F-value was 5.554 and the p-value was smaller than 0.05; and (3) there was an interaction of effect between the learning models and the learning interests on the Biology learning outcome of the students of Senior Secondary Schools of Grobogan Regency as indicated by the result of the two-way analysis of variance (ANOVA) in which the F-value was 4.434, and the p-value was smaller than 0.05.The highest average score in Biology learning of the students with the PBL model and with the high leaning interest was 83.88, whereas the lowest score in Biology learning of the students with the PBL model and with the lowlearning interest was 74. 47.
