Abstract
This study aims to study whether there is a linear and significant relationship, which is positive and greater than mathematical abilities on student chemistry learning outcomes. The population in this study were all students of class XI MIPA of SMA Negeri 1 Lubuk Pakam which consisted of 7 classes. The research sample is one class taken by purposive technique. This study uses 15 objective test instruments that have been questioned for validity, suitability, power differences and reliability of 0.806 (high) for mathematical ability data and reliability of 0.799 (high) for chemistry learning outcome data. For the first hypothesis test results namely linearity regression test using ANAVA regression test shows Fcount> Ftable (30.7503> 4.13), for the second hypothesis test result is a comparison test using the product moment test shows rcount> rtable (0.6891> 0.329). Based on hypothesis testing, then Ho is rejected and accepted that there is a linear and significant relationship and there is a positive conflict between mathematical ability and student chemistry learning outcomes. To test the coefficient of determination determines whether the ability of mathematical agreement with student chemistry learning outcomes is 47.49% while 52.51% is influenced by other factors.

Summary
Garam dalam mata pelajaran kimia merupakan materi pokok yang sebagian besar berisi hitungan matematika yang meliputi operasi tambah (+), kurang (-), bagi (:), kali (x), akar (√) dan logaritma (log). Pada beberapa materi kimia penguasaan konsep matematika merupakan prasyarat untuk dapat memahami pembelajaran kimia dengan baik. Kemampuan matematika diperlukan pada materi Hidrolisis Garam karena materi ini memerlukan pemahaman konsep dalam perhitungan matematika. Misalnya pada penelitian yang pernah dilakukan oleh Cahyono dkk., (2016), “Ada korelasi positif yang signifikan antara kemampuan numerik dan kreativitas dengan prestasi siswa pada materi Hidrolisis Garam”. Hal ini menunjukkan “Ada hubungan yang signifikan antara kemampuan numerik dan kreativitas dengan prestasi siswa kelas XI SMA Negeri 2 Karanganyar”. Pada penelitiannya menunjukkan bahwa tidak terdapat pengaruh kemampuan matematika tinggi dan rendah terhadap prestasi belajar kognitif dan afektif siswa pada materi pokok Hidrolisis Garam, yang ditunjukkan dengan hasi uji anava dua jalan dengan sel tak sama dimana p-value > nilai sig (0,05). Rancangan penelitian ini adalah rancangan penelitian korelasi dengan regresi linier sederhana
