Determination of Optimum Operating Condition on the Extraction of Oil from the Seed of Jarak Tiang (Ricinus communis Linn) Using Organic Solvent

The increasing of demand for fuel oil is a problem that unavoidable and will continue to occur due to the increasing number of human population. Oil reserves would not be possible to grow despite of the increasing of continues exploration, which will result the opposite. It is necessary to look for other alternatives to replace these fuels. One is through the use of bio-diesel which can be obtained from plants that are environmentally friendly and renewable. The Jarak Tiang Plant (ricinus communis Linn) is one type of plant that can be used as raw material for bio-diesel.  Seeds from these plants have a high oil content, i.e 40-55%. Part of the Jarak plant that can be used to make bio-diesel is the seed. The first step of the synthesis of bio-diesel from the seed of Jarak plant is oil extraction using organic solvents. Results obtained from this study indicate that the solvent that gave the largest yield is a mixture of methanol-chloroform for 60 minutes. The lowest acid number and viscosity obtained from methanol-chloroform solvent mixture for 120 minutes. The lowest iodine number obtained from the solvent n-hexane for 120 minutes. While the flash point for every variation of the same value i.e.  190 deg. Celsius.

  1. mau tanya,ini ekstraksi minyak’y melauli sokletasi atau ekstraksi cair2??
    boleh tau??
    kebetulan TA saya jg menggunakan biji jarak,dan saya menggunakan metode sokletasi untuk isolasi minyaknya,namun saya masi bingung mengenai proses’y..
    mohon bantuannya…

  2. ekstraksinya pake sokletasi. biji dtumbuk dl sblm ekstraksi. stlh minyaknya dpt didistilasi….

  3. I think this website has some really excellent information for everyone. “To be able to be caught up into the world of thought — that is being educated.” by Edith Hamilton.
