Renal failure was the standard end line of various urinary and renal tractus. Malnutrition among hemodialysis patients can be estimated using Subjective Global Assessment (SGA)-Dialysis Malnutrition Score (DMS) which is simple and reliable. The purpose of this research was to know the relationship between energy intake, protein, and potassium with nutritional status SGA in renal failure patients who were treated by hemodialysis in hospital Dr. M. Yunus Bengkulu. The design of this research was analytical observational by using prospective cohort approach. The number of respondents was 57 patient. Recall method was used to measure intake of energy, protein, and potassium with 2 × 24 h recall a week, as well as the measurement of SGA-DMS. Bivariate statistical tests using correlation are testing the significance of the relationship or difference with a 95 % confidence level and with α = 5 %. There was a relationship between the protein intake (p = 0.035) with SGA, there was no relationship between the energy intake (p = 0.242) with SGA, and there was no link between intake of potassium with SGA (p = 0.603) in chronic renal failure patients undergoing hemodialysis. This study showed which is no significant relationship between energy intake with SGA, there was a relationship of protein intake with SGA and there was no relationship between intake of potassium with SGA.
