Generally lubricants that are often found in the market are made from petroleum or petroleum base oil. With the depletion of petroleum reserves, the basic raw material for making lubricating oil is less, which can meet the needs of Indonesia. This is predicted to lead to scarcity of lubricants in the market or the increasingly expensive lubricants due to imports from abroad. Palm Fatty Acid Destilate (PFAD) has a high enough potential to be used as a raw material for oleochemical products, one of which is solid lubricant. This is due to the composition of the fatty acids found in PFAD not much different from the composition of fatty acids found in palm oil. This research aims to determine the formulation of solid lubricants (grease) from PFAD and compound (Al-Ca) metal soap as thickener which has the characteristics of approaching SNI solid lubricants and knowing the quality of the solid lubricants produced. The method used in making solid lubricants (grease) consists of two steps. The first step is the process of making mixed metal soap (Al-Ca) by mixing PFAD and Al(OH)3 - Ca(OH)¬2 and analyzing the mixed metal soap. The second stage is the manufacture of solid lubricants (grease) from mixed metal soap (Al-Ca) and PFAD and analyzes the products produced. Based on the research that has been done, the optimum solid lubricant that is in accordance with SNI standards is obtained in the composition A1: B1, A1 is the ratio of Al(OH)3:Ca(OH)2 = 90%:10% and B1 which is the ratio of metal soaps: PFAD = 10 %: 90%, so the density is 0,95 gr / ml and the penetration value is 194 (25 0C), the dropping point is 9710C and NLGI 4.
