Latar Belakang: Permasalahan gizi yang sering dialami wanita dewasa biasanya disebabkan oleh asupan zat gizi kurang yang berujung berisiko malnutrisi salah satunya KEK. Persiapan masa pra-konsepsi perlu diprioritaskan untuk wanita dewasa dalam menciptakan generasi berkualitas sehingga perlunya memerhatikan status gizi dan kesehatan.
Tujuan: Mengetahui hubungan tingkat kecukupan energi dan persepsi citra tubuh dengan kejadian KEK pada mahasiswi FISIP UIN Walisongo Semarang.
Metode: Penelitian analitik dengan desain cross sectional yang dilakukan di FISIP UIN Walisongo Semarang dengan sampel 77 responden. Menggunakan accidental sampling. Data tingkat kecukupan energi diperoleh menggunakan metode SQ-FFQ. Data persepsi citra tubuh menggunakan instrumen BSQ-16. Analisis bivariat menggunakan uji korelasi eta dan uji korelasi Koefisien Kontingensi. Analisis multivariat menggunakan uji regresi logistik.
Hasil: Hasil analisis bivariat hubungan tingkat kecukupan energi dengan kejadian KEK (p=<0.001) dan persepsi citra tubuh dengan kejadian KEK (p=0.012). Hasil analisis multivariat hubungan tingkat kecukupan energi paling berpengaruh terhadap KEK (p=<0.001; OR=53.046).
Kesimpulan: Terdapat hubungan tingkat kecukupan energi dan persepsi citra tubuh dengan kejadian KEK. Variabel paling berpengaruh terhadap kejadian KEK pada mahasiswi FISIP UIN Walisongo Semarang adalah tingkat kecukupan energi.

ABSTRACT:
Background: Nutritional problems that are often experienced by adult women are caused by insufficient nutritional intake which is at risk of malnutrition, one of which is CED. Pre-conception preparation needs to be prioritized to create a quality generation that needs to pay attention to nutrition and health status.
Objective: Analyze the relationship between the level of energy adequacy and body image perception with the incidence of CED in female FISIP students of UIN Walisongo Semarang.
Method: Analytical research with a cross sectional design conducted at FISIP UIN Walisongo Semarang with a sample of 77 respondents. Using accidental sampling. Data on energy adequacy level was obtained using the SQ-FFQ method. Body image perception data using BSQ-16 instrument. Bivariate analysis using eta correlation test and Contingency Coefficient correlation test. Multivariate analysis using logistic regression test.
Result: The results of bivariate analysis of the relationship between the level of energy adequacy with the incidence of CED (p=<0.001) and the perception of body image with the incidence of CED (p=0.012). The results of multivariate analysis of the relationship between the level of energy adequacy is most influential on CED (p=<0.001; OR=53.046).
Conclusion: There is a relationship between the level of energy adequacy and body image perception with the incidence of CED. The most influential variable on the incidence of CED in female FISIP students of UIN Walisongo Semarang is the level of energy adequacy.
