    KONVERSI BATANG SAWIT MENJADI BIO OIL DENGAN KATALIS Ni.Mo/LEMPUNG CENGAR
    (2013-04-20) Dewi, Dyah Mustika; Bahri Syaiful; Sahan Yusnimar
    Petroleum is non-reneweble fuel sources, its production decline gradually, while consumption increase significantly. Therefore it is necessary to find a new alternative energy, such as bio oil from a waste of palm plantation such as stem palm. Stem palm can be converted to bio oil by pyrolysis process using Ni.Mo/Cengar Clay as a catalyst. This research is aimed to determine the ratio effect between weight of catalyst (grams) and sample weight (grams) (0:50; 0,25:50; 0,75:50; 1,25: 50) respectively. In the pyrolysis process is used 500ml silinap 280-M as heating media and temperature 330oC. The maximum yield of bio oil is around 70,54% under ratio catalyst : sample (0,75: 50). Bio oil properties having density of 0,988 g/ml, 10,74 cSt viscosity, flash point 52 0C, and the acidity content 71,34 g NaOH/g sample. Based on GC-MS analysis is found that bio oil contain several organic compounds, such as acids, ketones, aldehydes, phenols, alcohols, ect. It can be concluded that bio oil can be further processed into alternative energy sources instead of petroleum

    Recovery Minyak dari Spent Bleaching Earth (SBE)
    (2013-03-21) Saputra, Ade Berlian; Sahan Yusnimar; Zahrina Ida
    The highest waste of crude pulm oil (CPO) refinery industry is spent bleaching earth (SBE), which it usually handling by landfill. SBE still contain high vegetable oil approximately 20-40%, and can be potential for utilized. This research aims is to get the oil yield maximum by using solvent extraction under solvent and particle size variations. Oil recovered of this process can be used as a raw material for biodiesel production. Based on this result, it has been found that solvent and particle size variations were influenced of the oil yield. The oil yield is 22.01% whish obtained by using n-hexane, 19.58% by ethanol and 21.07% by acetone. The particle size variations is affected to the oil yield, for example the oil yield of SBE by using n-hexane are 18.57% for 60 mesh, 20.03% for 100 mesh, and 22.01% for 200 mesh. The analysed result of oil recovered under conditions n-hexane as a solvent with 200 mesh particle size are water content 0.068%, density 880.3 kg/m3, viscosity 45.69 cSt, and FFA content 14.50%. This oil properties is compared to raw material and biodiesel standard will be concluded that the oil recovered of SBE can be use as a raw material alternative for biodiesel production.

    Regenerasi Spent Bleaching Earth (SBE) dan Aplikasinya Pada Adsorpsi Ion Cu(II)
    (2013-01-16) Aulia, Barkatul; Sahan Yusnimar; Zahrina Ida
    Spent bleaching earth (SBE) is an adsorbent waste of bleaching units in the crude palm oil (CPO) refinery industry. Principally, the SBE can be regenerated and reused as an adsorbent. This research aims to regenerate SBE and determine the influence of particle size variations and temperature in the activation of regenerated spent bleaching earth (RSBE) adsorption on Cu(II) ionic. Particle sizes variations is used (60, 100 and 200 mesh) and the activation temperature (270, 370 and 470oC) to obtained the best conditions for the regeneration process. This regeneration process through the remaining stages of oil extraction using hexane solvent. Furthermore, the material is activated with 3% HCL acid and then reactivated using high temperatures. The result of SBE regeneration (RSBE) tested the adsorption ability in solution ion Cu(II) 20 mg/Liter for 10 hours. Based on the results showed that the best RSBE adsorption power on the condition that the particle sized of 200 mesh and activation temperature 470oC with adsorption 2,002 mg Cu/g RSBE.
