Universitas Indonesia memiliki organisasi paguyuban daerah untuk memfasilitasi mahasiswa rantau dalam menghadapi kehidupan kampus. Namun masih ada kasus mahasiswa rantau yang meninggal karena sakit dan kurang mendapat layanan kesehatan. Penelitian ini bertujuan untuk mengetahui determinan perilaku mencari layanan kesehatan pada mahasiswa rantau Universitas Indonesia tahun 2024. Penelitian ini menggunakan desain cross-sectional. Data dikumpulkan menggunakan self-administered questionnare oleh mahasiswa S1 Reguler Universitas Indonesia yang terdaftar sebagai anggota di paguyuban daerah hingga Mei 2024 yang berjumlah 299 mahasiswa. Data dianalisis menggunakan uji chi-square untuk mengetahui hubungan antara variabel independen terhadap variabel dependen. Hasil penelitian menunjukkan bahwa 217 (76,2%) responden pernah mencari layanan kesehatan di kampus selama berkuliah di Universitas Indonesia. Penelitian ini juga menunjukkan hubungan yang signifikan secara statistik antara asuransi kesehatan (p<0,001; OR=6,32; 95% CI=3,59–11,13), literasi kesehatan (p=0,004; OR=2,12; 95% CI=1,26–3,56), dan dukungan sosial (p=0,011; OR=0,51;95% CI=0,30–0,86) dengan perilaku mencari layanan kesehatan. Saran yang dapat diberikan berdasarkan penelitian ini adalah meningkatkan sosialisasi layanan kesehatan di lingkungan kampus oleh kakak asuh dari masing-masing paguyuban, terutama saat masa Orientasi Kehidupan Kampus sebagai bentuk peningkatan promosi kesehatan di lingkungan Universitas Indonesia.

The University of Indonesia has regional community organizations to facilitate overseas students in facing campus life. However, there are still cases of overseas students who have died due to illness and lack of healthcare services. This study aims to determine the determinants of health service-seeking behavior among overseas students at the University of Indonesia in 2024. This study uses a cross-sectional design. Data were collected using a self-administered questionnaire by undergraduate students of the University of Indonesia who were registered as members of regional communities until May 2024, totaling 299 students. Data were analyzed using the chi-square test to determine the relationship between independent variables and the dependent variable. The results showed that 217 (76.2%) respondents had sought health services on campus while studying at the University of Indonesia. This study also showed a statistically significant relationship between health insurance (p<0.001; OR=6.32; 95% CI=3.59– 11.13), health literacy (p=0.004; OR=2.12; 95% CI=1.26–3.56), and social support (p=0.011; OR=0.51; 95% CI=0.30–0.86) with health service-seeking behavior. Therefore, the recommendations based on this study are to enhance the socialization of health services within the campus environment by senior mentors from each regional community, especially during the Campus Life Orientation period, as a form of health promotion improvement at the University of Indonesia.
