Abstract
Permintaan energi yang terus meningkat telah mendorong adanya pengembangan energi alternatif. Nyamplung (calophyllum inophyllum) merupakan tanaman yang dapat dijadikan sebagai sumber daya untuk pengembangan energi alternatif. Minyak dari biji nyamplung dapat digunakan untuk produksi fatty acid methyl esters (FAME). Ester asam lemak dapat diperoleh dengan cara hidrolisis lipid dan esterifikasi asam lemak melalui LP-HTL. Minyak biji nyamplung diperoleh dengan cara pengepresan biji nyamplung kering sebagai feedstock. Minyak biji nyamplung dengan pelarut metanol diproses melalui LP-HTL pada suhu 250ºC selama 60 menit dan tekanan bervariasi yaitu 1; 1,5; dan 2 MPa. Karakterisasi produk minyak LP-HTL meliputi densitas, viskositas kinematik, nilai kalor, serta komponen kimia yang dianalisis dengan GC-MS. Didapatkan yield tertinggi produk minyak LP-HTL pada variasi tekanan 1,5 MPa, yaitu 80,2097%. Nilai densitas dan viskositas kinematik tiga produk minyak LP-HTL berada dalam rentang ASTM D6751. Nilai viskositas kinematik produk minyak LP-HTL dengan variasi tekanan 1 dan 1,5 MPa juga berada dalam rentang SNI 7182:2015. Sementara itu, nilai kalor produk minyak LP-HTL dengan variasi tekanan 1 dan 1,5 MPa berada dalam rentang EN (14214). Komponen kimia minyak biji nyamplung didominasi oleh asam lemak linoleat sedangkan komponen kimia produk minyak LP-HTL didominasi oleh metil elaidat/oleat. Persentase FAME yang didapatkan dari tiga produk LP-HTL dengan variasi tekanan 1; 1,5; dan 2 MPa, masing-masing adalah 95,69; 88,73; dan 91,04%.

The increasing demand for energy has encouraged the development of alternative energy. Nyamplung (calophyllum inophyllum) is a plant that can be used as a resource for alternative energy development. Oil from nyamplung seeds can be used for the production of fatty acid methyl esters (FAME). Fatty acid esters can be obtained by lipid hydrolysis and fatty acid esterification through LP-HTL. Nyamplung seed oil is obtained by pressing dried nyamplung seeds as feedstock. Nyamplung seed oil with methanol solvent was processed through LP-HTL at 250ºC for 60 minutes and varied pressures of 1; 1.5; and 2 MPa. Characterization of LP-HTL oil product includes density, kinematic viscosity, calorific value, and chemical components analyzed by GC-MS. The highest yield of LP-HTL oil product was obtained at a pressure variation of 1.5 MPa, which was 80.2097%. The density and kinematic viscosity values of three LP-HTL oil products are within the ASTM D6751 range. The kinematic viscosity values of LP-HTL oil products with pressure variations of 1 and 1.5 MPa is also within the range of SNI 7182:2015. Meanwhile, the calorific value of LP-HTL oil products with pressure variations of 1 and 1.5 MPa is within the EN (14214) range. The chemical components of nyamplung seed oil are dominated by linoleic fatty acids while the chemical components of LP-HTL oil products are dominated by methyl elaidate/oleic. The FAME obtained from three LP-HTL products with pressure variations of 1; 1.5; and 2 MPa were 95.69; 88.73; and 91.04%, respectively.
