Nyamplung (Calophyllum inophyllum L.) is a species of plant which is widely spread in Indonesia. Nyamplung plant has high productivity, reaching 20 tonne/ha/year. Research about Nyamplung plant usually focused on Nyamplung seed oil as biofuel, even though resin in Nyamplung seed has many potentials. Nyamplung seed oil contain resin up to 10-20%. Resin from Nyamplung seed oil can be used for other purposes, for example resin as cosmetic active ingredient or as medicine in pharmaceutical field. Separation method of resin and oil from Nyamplung seed used in this research is extraction with two type of solvents. Resin extraction from Nyamplung seed modelling is needed to determine the solvent ratio which gives the optimum gain of resin and oil. The purposes of this research are to study Nyamplung seed extraction equilibrium and to determine the best solvent ratio which gives the optimum gain of resin and oil. In this research, Nyamplung seed extraction is modelled using Aspen Plus and Microsoft Excel. This research used data from Kartika et al. in 2018; Afifah, N in 2019; and Mandiri, R & Saputri, D in 2019. In the equilibrium calculation, resin is represented with abietic acid and oil is represented with oleic acid. This research modelled the equilibrium of the components in the room temperature. The best oil yield (99%) is obtained when the solvent (n-hexane : methanol) ratio is 3:1. While the best resin yield obtained at solvent ratio 1:2. Optimum resin and oil yield obtained at solvent ratio 3:2, which gives resin gain in metanol phase of 73% and oil gain in hexane phase of 89%.
