<![CDATA[Library facilities play a crucial role in fostering students' reading interest; comprehensive and adequate facilities generate greater enthusiasm, interest, and a willingness to read among students. This study aims to determine the influence of library facilities on students' reading interest at SMKS St. Nahanson Parapat Sipoholon during the 2025/2026 academic year. An inferential quantitative research method was employed. The study population consisted of all 354 students at SMKS St. Nahanson Parapat Sipoholon. A sample size of 54 students was determined based on Arikunto's guidelines, utilizing a purposive sampling technique (sampling based on specific criteria). Data were collected using a closed-ended questionnaire comprising 55 items. The analysis results indicate that library facilities do influence students' reading interest at SMKS St. Nahanson Parapat Sipoholon for the 2025/2026 academic year. This is evidenced by the following analyses: 1) Analysis requirement tests: a) Normality test yielded an Asymp. Sig. (2-tailed) value of 0.200 (> 0.05); b) Linearity test yielded a significance value for deviation from linearity of 0.780 (> 0.05). 2) Hypothesis testing: a) Correlation coefficient test between variables X and Y yielded an rxy value of 0.733 (> 0.263), indicating a positive relationship between variable X and variable Y; b) Significance test of the relationship yielded a tcount value of 6.877 (> 1.675), indicating a significant relationship between variable X and variable Y; c) Regression equation test yielded the equation Ŷ = 47.311 + 0.318X; d) Hypothesis testing using the F-test yielded Fcount > Ftable (47.299 > 4.023), meaning the alternative hypothesis (Ha) was accepted and the null hypothesis (H0) was rejected. 3) Regression coefficient of determination (R²) test = 47.6%. Thus, the research results indicate that library facilities account for 47.6% of the influence on students' reading interest at SMKS St. Nahanson Parapat Sipoholon]]>
