Anisa Humairah (2025). The Influence of Family Environment and Self-Efficacy on the Academic Achievement of Students at SMPN 1 Lhoknga. Under the supervision of Dra. Musfiana, MM and Dr. Irsyadillah, S.Pd., M.Sc. This study was motivated by the low academic achievement of students, which is presumed to be influenced by the family environment and self-efficacy. A lack of support from the family environment and students’ low confidence in their learning abilities may negatively affect their academic performance. This study aimed to examine the influence of the family environment and self-efficacy on the academic achievement of eighth-grade students at SMPN 1 Lhoknga. The research employed a quantitative approach with a descriptive research design. The population consisted of all eighth-grade students at SMPN 1 Lhoknga, totaling 80 students. The sample size was determined using the Slovin formula with a 5% margin of error, resulting in a sample of 66 students selected through simple random sampling. Data were collected using questionnaires, while the data were analyzed using simple linear regression and multiple linear regression. Hypothesis testing was conducted through the t-test and F-test. The results of the analysis revealed that the regression equation obtained was Y = 19.851 + 0.420X₁ + 0.592X₂. The t-test results indicated that both the family environment and self-efficacy variables had a significant influence on academic achievement, with t-count values of 6.404 and 6.133, respectively, which were higher than the t-table value of 1.669 (α = 0.05). The F-test results also showed that the F-count exceeded the F-table value, with a significance level of < 0.05. Therefore, it can be concluded that the family environment and self-efficacy have a significant positive effect on the academic achievement of eighth-grade students at SMPN 1 Lhoknga.
