Pengaruh Komunikasi Interpersonal terhadap Keberlanjutan Sebuah Hubungan Melalui Metode Split Bill

Abstract

Komunikasi interpersonal memegang peranan penting dalam hubungan romantis. Penelitian ini mengkaji pengaruh komunikasi interpersonal terhadap keberlanjutan hubungan melalui metode split bill pada mahasiswa Fakultas Psikologi Universitas Medan Area. Menggunakan pendekatan kuantitatif dengan survei, penelitian ini melibatkan 499 mahasiswa sebagai populasi dan 83 mahasiswa sebagai sampel yang dipilih melalui cluster sampling. Data dikumpulkan melalui kuesioner yang diuji validitas dan reliabilitasnya, kemudian dianalisis menggunakan uji T parsial, regresi linear sederhana, dan uji koefisien determinasi berganda (R²). Hasil uji T parsial menunjukkan thitung sebesar 6,547 lebih besar dari t-tabel sebesar 1,989 pada tingkat signifikansi 5%, sehingga H1 diterima dan H0 ditolak. Ini mengindikasikan bahwa komunikasi interpersonal memiliki pengaruh signifikan terhadap keberlanjutan hubungan melalui metode split bill. Analisis regresi linear sederhana menunjukkan adanya hubungan linier yang signifikan antara komunikasi interpersonal dan keberlanjutan hubungan, dengan koefisien regresi (b) positif. Uji koefisien determinasi berganda (R²) menunjukkan bahwa 45,6% variabilitas dalam keberlanjutan hubungan dapat dijelaskan oleh komunikasi interpersonal melalui metode split bill. Kesimpulannya, komunikasi interpersonal berpengaruh signifikan terhadap keberlanjutan hubungan melalui metode split bill. Interpersonal communication plays an important role in romantic relationships. This research examines the influence of interpersonal communication on sustainability relationship through the split bill method among students at the Faculty of Psychology at the University Medan Area. Using a quantitative approach with a survey, this research involving 499 students as a population and 83 students as a sample selected through cluster sampling. Data was collected through a questionnaire tested for validity and reliability, then analyzed using the partial T test, simple linear regression, and multiple coefficient of determination (R²) test. T test results partial shows that the tcount is 6.547 which is greater than the t-table of 1.989 at a significance level of 5%, so H1 is accepted and H0 is rejected. This indicates that interpersonal communication has a significant influence towards the sustainability of the relationship through the split bill method. Linear regression analysis simple shows the existence of a significant linear relationship between communication interpersonal and relationship sustainability, with a positive regression coefficient (b). Test the coefficient of multiple determination (R²) indicates that 45.6% variability in the sustainability of the relationship can be explained by interpersonal communication through split bill method. In conclusion, interpersonal communication has a significant effect towards the sustainability of the relationship through the split bill method.
