Marriage. Woman subject: L Education (General) description: This study aims to determine the effect of family dysfunction on student learning motivation in sociology subjects and how much influence. This research uses quantitative method with survey research type. The population in this study was class XII students of SMA Negeri 3 Kota Serang, with a sample of 85 students taken from classes XII-9 and XII-11 using purposive sampling technique. The data analysis techniques used include descriptive analysis and inferential analysis, which consists of prerequisite analysis and hypothesis testing using simple linear regression analysis. Based on simple linear regression analysis, the Constant (α) value is 174.907 and the regression coefficient (b) value is -1.045 with a significance value of 0.000 (p < 0.05). This means that every one unit increase in the family dysfunction variable will reduce student learning motivation by 1.045 units. In addition, the r-square value of 0.473 indicates that family dysfunction contributes 47.3% to the student learning motivation variable. Through a theoretical approach, it is found that dysfunctional families fail to perform the four structural functions optimally. The adaptation function does not work because the family is unable to fulfil the material and emotional needs of children; the goal achievement function is absent because there is no direction and support for the learning process; the integration function is disrupted by conflict and tenuous relationships between family members; and the latency function continues but is distorted, where dysfunctional values are inherited and considered normal. These failures are systemic and interrelated, creating a family environment that is not conducive to character building and student learning motivation. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/49638/1/Dede%20Annisa%20Fauziah_2290200051_FULLTEXT.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49638/2/Dede%20Annisa%20Fauziah_2290200051_CP.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49638/3/Dede%20Annisa%20Fauziah_2290200051_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49638/4/Dede%20Annisa%20Fauziah_2290200051_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49638/5/Dede%20Annisa%20Fauziah_2290200051_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49638/6/Dede%20Annisa%20Fauziah_2290200051_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49638/7/Dede%20Annisa%20Fauziah_2290200051_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49638/8/Dede%20Annisa%20Fauziah_2290200051_REF.pdf format: text language: id identifier: https://eprints.untirta.ac.id/49638/9/Dede%20Annisa%20Fauziah_2290200051_LAMP.pdf identifier: FAUZIAH, DEDE ANNISA (2025) Pengaruh Disfungsi Keluarga terhadap Motivasi Belajar Mata Pelajaran Sosiologi pada Siswa Kelas XII SMA Negeri 3 Kota Serang.
