Tujuan penelitian ini untuk mengetahui adanya hubungan antara kemampuan memori terhadap hasil belajar biologi ranah kognitif, hubungan antara motivasi belajar terhadap hasil belajar biologi ranah kognitif, dan hubungan antara kemampuan memori dan motivasi belajar terhadap hasil belajar biologi ranah kognitif siswa kelas X SMA Muhammadiyah Tarakan Penilitian ini dilakukan selama bulan Mei 2015 di SMA Muhammadiyah Tarakan. Penelitian ini menggunakan metode penelitian deskriptif korelasi dengan populasi seluruh siswa kelas X SMA Muhammadiyah Tarakan Tahun Ajaran 2015/2016, dan sampel yaitu kelas X MIA 1 dan kelas X MIA 2. Teknik pengambilan sampel menggunakan Purposive Sampling dan teknik pengumpulan data menggunakan teknik penelitian ini adalah uji normalitas, uji homocedastisistas, uji linearitas, uji multikolinearitas, uji korelasi, uji linearitas regresi, uji regresi sederhana, uji regresi ganda, dan uji hipotesis. Pengujian dilakukan dengan bantuan software SPSS 16.0 for windows. Berdasarkan hasil analisis data uji korelasi kemampuan memori terhadap hasil belajar biologi ranah kognitif siswa kelas X dapat dilihat yaitu sebesar 0.436 ? 0.187. Hasil uji korelasi motivasi belajar terhadap hasil belajar biologi ranah kognitif siswa kelas X dapat dilihat yaitu sebesar 0.468 ? 0.187. Hasil uji korelasi kemampuan memori dan motivasi belajar terhadap hasil belajar biologi ranah kognitif siswa kelas X dapat dilihat yaitu sebesar 0.584 ? 0.187. berarti rhitung lebih besar dari rtabel (1.734 ? 0.187) artinya terdapat hubungan yang signifikan antara kemampuan memori dan motivasi belajar terhadap hasil belajar biologi ranah kognitif.

The objective of this research is to know the relationship between memory ability to the learning outcomes cognitive biological sphere, the relationship between motivation toward the learning outcomes cognitive biological realm, and the relationship between memory ability and motivation to learn the learning outcomes of cognitive biology at the tenth grade students of SMA Muhammadiyah Tarakan. This research was conducted during the month of May 2015 at SMA Muhammadiyah Tarakan. This research uses descriptive method correlation with the population of the all students at SMA Muhammadiyah Tarakan 2015/2016 academic year, and the sample is the tenth grade MIA 1 and the tenth grade MIA 2. The sampling technique used purposive sampling and data collection techniques using research techniques are normality test, homocedastisistas, linarite test, multicollinearity test, correlation, regression linearity test, simple regression, multiple regression test, and hypothesis testing. The testing is done with the help of software SPSS 16.0 for windows. Based on the analysis of data correlation test memory ability to the learning outcomes of cognitive biology at the tenth grade can be seen in the amount of 0.436> 0.187. The results of correlation test motivation toward learning outcomes cognitive biology at the tenth grade can be seen in the amount of 0.468 > 0.187. The results of correlation test memory ability and motivation toward learning outcomes cognitive biology at the tenth grade can be seen in the amount of 0.584> 0, 187, it means that rcount larger than rtable (1.734 0.187) it means that there is a significant relationship between memory ability and motivation to learn to biology cognitive learning outcomes.
