%X N-methyl glukamide surfactant has been synthesized from waste cooking oil  and N-methyl glukamine. Were synthesized via indirect amidation of methyl ester  used frying oil. Products was carried out by FT-IR and Furthermore, N-methyl  glukamide as synthetic product was characterized as surfactant.  Transesterification of used frying oil with base catalyst (NaOH) produced  mixture of methyl ester, Le methyl ester in 94,42%. From mixture of methyl ester,  i.e methyl ester of palmitate, oleate, isostearate, and trans-9-octadecinoic acid  withpercent conversion 33,28%. Amidation of methyl esters with N-methyl  glukamine (2:3) for 3 h produced the related N-methyl glukamide in 90.49%.  Characterization as surfactant showed that the N-methyl glukamide could  reduced the surface tension of water from 65,2 mN/m to16,27 mN/m. Foam was  stable until 1.5 hours of observed time, petrol-water- palm oil and surfactant system  has 100 % emulsion index, stability emulsions have observed until 4 days. Further  more, HLB value of surfactant is 8,045 with characteristic dispersion in the water  and can be applied as metting agent.  Key words: Surfactant, N-methyl glukamide, HLB value (Hydrophyle Lypophyle  Balance)
