Abstract
Pengetahuan kesehatan tubuh merupakan salah satu faktor yang dapat memengaruhi perilaku seseorang dalam menerapkan pola makan sehat. Penelitian ini bertujuan untuk mengetahui pengaruh pengetahuan kesehatan tubuh terhadap perilaku makan sehat peserta senam Sanggar Julie. Penelitian ini merupakan penelitian kuantitatif dengan metode survei dan pendekatan cross-sectional. Sampel penelitian berjumlah 52 peserta senam aktif yang dipilih menggunakan teknik simple random sampling. Instrumen penelitian berupa tes pengetahuan kesehatan tubuh sebanyak 19 butir soal pilihan ganda dan angket perilaku makan sehat sebanyak 11 pernyataan menggunakan skala Likert yang telah memenuhi uji validitas dan reliabilitas. Analisis data dilakukan menggunakan analisis deskriptif, uji normalitas, uji linearitas, uji heteroskedastisitas, analisis regresi linear sederhana, uji parsial (uji t), dan koefisien determinasi (R²). Hasil penelitian menunjukkan bahwa tidak terdapat pengaruh yang signifikan antara pengetahuan kesehatan tubuh terhadap perilaku makan sehat peserta senam Sanggar Julie, ditunjukkan oleh nilai t hitung sebesar 1,908 yang lebih kecil daripada t tabel sebesar 2,009 serta nilai signifikansi sebesar 0,062 (p > 0,05). Nilai koefisien determinasi (R²) sebesar 0,068 menunjukkan bahwa pengetahuan kesehatan tubuh hanya mampu menjelaskan variasi perilaku makan sehat sebesar 6,8%, sedangkan 93,2% dipengaruhi oleh faktor lain yang tidak diteliti. Dengan demikian, dapat disimpulkan bahwa pengetahuan kesehatan tubuh tidak berpengaruh secara signifikan terhadap perilaku makan sehat peserta senam Sanggar Julie. Body health knowledge is one of the factors that may influence an individual's healthy eating behavior. This study aimed to determine the effect of body health knowledge on the healthy eating behavior of participants at Sanggar Julie Aerobics Studio. This study employed a quantitative research design using a survey method with a cross-sectional approach. The sample consisted of 52 active aerobics participants selected through simple random sampling. The research instruments included a 19- item multiple-choice test to measure body health knowledge and an 11-item healthy eating behavior questionnaire using a Likert scale. Both instruments met the validity and reliability requirements. Data were analyzed using descriptive statistics, normality test, linearity test, heteroscedasticity test, simple linear regression analysis, partial ttest, and the coefficient of determination (R²). The results showed that there was no significant effect of body health knowledge on the healthy eating behavior of Sanggar Julie aerobics participants. This finding was indicated by a calculated t-value of 1.908, which was lower than the t-table value of 2.009, and a significance value of 0.062 (p > 0.05). The coefficient of determination (R²) was 0.068, indicating that body health knowledge explained 6.8% of the variance in healthy eating behavior, while the remaining 93.2% was influenced by other factors not examined in this study. Therefore, it can be concluded that body health knowledge does not have a significant effect on the healthy eating behavior of Sanggar Julie aerobics participants.
