Pembuatan Biodiesel dari Minyak Sawit Secara Kontinyu Dalam Model Reaktor Berisian
Biodiesel is an alternative fuel made from tree-plants for diesel machine containing alkyl ester of fatty acids.
Generally, biodiesel process is carried out in batch with resident time about 90 minutes. For larger capacity,
biodiesel can be produced in continuous to make reaction time shorter. The aim of this research is to make
biodiesel in continuous using packed reactor model. The packed reactor model is designed to make the surface
contact between reactants with catalyst occurs in homogenizing stage. To evaluate the performance of reactor
followed by experiment, palm oil reacted with methanol catalysed by potassium hydroxide at 60oC, mole ratio of
palm oil: methanol are 5:1, 6:1, and 7:1, while the weight percentage of catalyst to palm oil are 0.5; 1; 1.5; and
2% respectively. The best characteristics obtained at mol ratio 7:1 with amount of catalyst 2%, i.e. density 0.864
g/cm3, flash point 1200C, viscosity 4.82 cst, pour point 130C, CCI 48.28, and FAME 98.14%.

On Yukawa Couplings in the Zee-Babu Model
The exact solution for neutrino mass matrix of the Zee-Babu modelis derived. The tribimaximal mixing imposes the conditions on the Yukawa couplings, from which the normal mass hierarchy ispreferred. The derived conditions give a possibility of maximal violation in the neutrino sector
