<![CDATA[This study aimed to determine the level of students' spiritual intelligence, the level of students' self-control, and the influence of spiritual intelligence on students' self-control at SMKN 1 Luwu Timur. This study employed a quantitative approach using an ex post facto research design. The population consisted of all Grade X and Grade XI students of SMKN 1 Luwu Timur, totaling 609 students. A sample of 86 students was selected using the Slovin formula with a 10% margin of error. Data were collected through questionnaires and documentation. The data were analyzed using descriptive statistics and inferential statistics, specifically multiple linear regression analysis, with the assistance of SPSS version 26. The results of the study indicated that: (1) the students' level of spiritual intelligence was in the moderate category, as reflected by the indicators of self-awareness (60%), purpose in life (51%), and holistic thinking (63%), all of which were predominantly classified as moderate; (2) the students' level of self-control was also in the moderate category, with 64 students (74%) classified as moderate, 14 students (16%) as high, and 8 students (9%) as low; and (3) spiritual intelligence had a significant influence on students' self-control. The simultaneous test showed an F-value of 1308.239 with a significance value of 0.000 < 0.05. The coefficient of determination (R²) of 0.980 indicated that spiritual intelligence contributed 98.0% to students' self-control, while the remaining 2.0% was influenced by other factors not examined in this study. Partially, the indicators of self-awareness and purpose in life had a significant effect on students' self-control, whereas the holistic thinking indicator did not have a significant effect. Therefore, the alternative hypothesis (Ha) was accepted, and the null hypothesis (H₀) was rejected.]]>
