aktorperlakuandantiga kali ulangan. faktorpertama (p) jenis pelarut dengan 3 taraf yaitu air, metanol 50% dan metanol 70%.faktorkedua (s) suhu ekstraksidengan 3 taraf yaitu 30, 45, dan 60oc. setiap ulangan diulang sebanyak 3 kali sehingga diperoleh 27 satuan percobaan. hasil penelitian menunjukkan bahwa rendemen oleoresin tertinggi diperoleh dari ekstraksi menggunakan pelarut air dengan suhu 30oc yaitu sebesar 22,17%. ekstrak oleoresin daun kari memiliki rendemen (6,7%-22%), bobot jenis (1,335-1,445), indeks bias (1,3338-1,3353), sisa pelarut (9,6%-36%), nilai total fenol (0,033 mggae/ml 0,053 mggae/ml) dan aktivitas antioksidan (22,6%-51%). setelah dilakukan analisis statistik diperoleh perlakuan yang paling berpengaruh adalah jenis pelarut diikuti suhu ekstraksi dan interaksi antara pelarut dan suhu ekstraksi. kata kunci : ekstraksi, oleoresin, pelarut, suhu ektraksi, abstract curry leaves or leaves koja is a leaf that often used in cooking as the scent of the vegetables , curry leaves contain volatile oil which can be extracted into oleoresins. product oleoresin indonesian market is still lacking, so it needs to be studied variations in temperature and solvent to produce a high yield of oleoresin. the advantage of oleoresin products can be used at low concentrations and have better thermal stability than essential oils. this study was conducted using a randomized block design consisting of two treatment factors and three replications. the first factor is solvent (p) with 3 levels of solvent : water, 50% methanol and 70% methanol. the second factor is temperature extraction (s) with 3 levels, namely 30, 45, and 60°c. each repetition was repeated 3 times to obtain 27 units of the experiment. the results showed that the highest yield of oleoresin was obtained from solvent extraction using water with a temperature of 30° c is equal to 22.17% . oleoresin extract of curry leaves has a yield ( 6.7 % -22 % ), the specific gravity ( 1.335 to 1.445 ), the refractive index ( 1.3338 to 1.3353 ), residual solvent ( 9.6 % -36 % ), the total value phenol ( 0,033 mggae / ml 0.053 mggae / ml ) and antioxidant activity ( 22.6 % -51 % ). after statistical analysis obtained by the treatment of the most influential is the type of solvent followed by the extraction temperature and the interaction between the solvent and the extraction temperature. keywords : extraction, oleoresin, solvent, temperature extraction.
