Papua nutmeg (Myristica argantea Warb) is indigenous of Fakfak, West Papua. The use of Papua nutmeg is still traditional, i.e. dried fruit, seed, and mace. The seed of Papua nutmeg contains a lipid that could be developed as an emulsifier such as monodiacylgycerol (MDAG). The study aimed to investigate the synthesis of MDAG from Papua nutmeg seed oil and its bioactivity against Staphylococcus aureus and Saccharomyces cerevisiae. Approximately 13 treatments were conducted to optimize the synthesis of MDGA based on the Central Composite Design of Response Surface Methodology (RSM). The parameters evaluated were temperature and reaction time. The result showed that the optimal temperature and reaction time for MDAG production were 42°C and 17 hours which produced 35% and its purity was 93%. The MDAG produced inhibited S. aureus and S. cerevisiae at the concentration 25 mg/ml. The chemical properties of MDAG from the Papua nutmeg contained monoacylglyserol (MAG) (23.35%), diacylglycerol (DAG) (1.87%), and triacylglycerol (TAG) (5.37%), as well as other fatty acids. Physicochemically, the MDAG had a melting point 53.554 °C, iod value 17.34, peroxide value 47.25 meq/1000 g, and purity 93.3%.
