description Biodiesel from the seed of nyamplung (Calophyllum inophyllum) is a promising business Indonesia, and large scale production is being developed. Even though the waste is still high protein content, the application is still limited. It is because of lack of information about the protein characteristic. The protein isolation process performed on the defatted seedcake to produce 22.09 ± 0.87 dB of protein concentrate with a brownish color, and the following Lab values are 44.37 ± 1.29, 9.68 ± 0.3 and 12.4 ± 0.78, respectively. The functional group of the extract and molecular weight were determined by FTIR and SDS-PAGE respectively. Chromatogram of FTIR showed that the protein concentrate of nyamplung has a group as a characterize of amide are C=O stretching at1658.78cm−1, N-H stretching at 3371.57cm−1, and NH bending at1543.05cm−1. The molecular size analysis showed the protein of nyamplung relatively have molecular weight were between 9.73 until 37.96 kDa.
