N2 - Anaerobic Digestion (AD) is an alternative technology used for treating food waste. Sodium content in food waste with a concentration of > 3.100 mg/L has the potential to cause inhibition. Sodium inhibition can be controlled with magnesium. In steady state conditions, the control phase shows the average Chemical Oxygen Demand (COD) removal 94.2 ± 3.34%, Soluble Chemical Oxygen Demand (SCOD) 98 ± 1%, Particulate Chemical Oxygen Demand (PCOD) 94 ± 3.6%, and formation of Volatile Fatty Acids (VFA) 1,800 ± 200 mg/L and hydrolysis rate 6.92 ± 0.32 mg.PCOD/L/d. The addition of MgSO4 in the test phase showed a significant difference in the formation of VFA to 1,066 ± 57.7 mg/L. While the average allowance for COD, SCOD, and PCOD did not show a significant difference with a value of 84.7 ± 6.8% respectively; 96 ± 1%; 83.3 ± 7.3%. The hydrolysis rate in the test phase also did not show a significant difference to 6.24 ± 0.57 mg.PCOD/L/d.
