Syaif Amrullah Alqusyairi *1 , Farida 2 , Suherman 3 1,2,3 Universitas Islam Negeri Raden Intan Lampung erysyaif@gmail.com *1 , farida@radenintan.ac.id 2 , suherman@radenintan.ac.id 3 Abstract The purpose of this study is to determine the relationship between environmental literacy and mathematical literacy on the ability of students' Computer Self Efficacy. This quantitative study uses a Correlational Design research design. The data collection techniques in this study were environmental literacy tests, mathematical literacy tests, and a Computer Self Efficacy ability questionnaire. The data analysis technique used is Simple and Multiple Linear Regression. Based on the results obtained from research and calculations of Simple and Multiple Linear Regression analysis, it was concluded that there is a relationship between environmental literacy and the ability of Computer Self Efficacy of students, there is a relationship between mathematical literacy and the ability of Computer Self Efficacy of students, and there is a relationship between environmental literacy and mathematical literacy with the ability of students' Computer Self Efficacy. The magnitude of the influence of environmental literacy and mathematical literacy on the ability of Computer Self Efficacy is 39.2%. Keywords: Environmental Literacy, Mathematical Literacy, Computer Self Efficacy Ability Abstrak Tujuan penelitian ini yaitu untuk mengetahui hubungan literasi lingkungan dan literasi matematis terhadap kemampuan Computer Self Efficacy peserta didik. Penelitian kuantitatif ini menggunakan desain penelitian Correlational Desaign. Teknik pengumpulan data dalam penelitian ini yaitu tes literasi lingkungan, tes literasi matematis, dan angket kemampuan Computer Self Efficacy. Teknik analisis data yang digunakan yaitu Regresi Linier Sederhana dan Berganda. Berdasarkan hasil yang diperoleh dari penelitian dan perhitungan analisis Regresi Linier Sederhana dan Berganda, diperoleh kesimpulan bahwa terdapat hubungan antara literasi lingkungan dengan kemampuan Computer Self Efficacy peserta didik, terdapat hubungan antara literasi matematis dengan kemampuan Computer Self Efficacy peserta didik, dan terdapat hubungan antara literasi lingkungan dan literasi matematis dengan kemampuan Computer Self Efficacy peserta didik. Besarnya pengaruh literasi lingkungan dan literasi matematis terhadap kemampuan Computer Self Efficacy yaitu sebesar 39,2%.
