13. The Process of making
biodiesel

14. 1. Collecting the Kapok
seeds
Kapok seed oil is
obtained from pressing the kapok seeds.
kapok seeds itself are getting
from Pasuruan, with a land area of kapok tree
is 12,604 ha and with the number
of 2,048,757 trees and the production reaches
4170 tons with a yield reached 7900 tons
of kapok seeds.

15. 2. Pressing the Kapok Seed
 Pressed kapok seeds were conducted to
obtain kapok seed oil. This pressing using a
screw press equipment because it
can produce maximum kapok seed oil.

17. 3. Oil filtering
 Oil filtering is done
to get more clean
oil and
free from particles or
dirt, this filter use the
filter press tool.

18. 4. Biodiesel Production
Process
 The process of making biodiesel is made from
the esterification process or
reaction processes from cotton seed
oil with methanol that catalyzed
by H2SO4 (sulfic acid) then continue with the
transesterification process
of esterification process
result with methanol that catalyzed
by NaOH (Natrium Hydroxide).

19. Esterification and
Transesterification Process

21. Economic Analysis
 Production cost of biodiesel from kapok seeds
oil for the capacity 65.000 Ton/year
- kapok seeds oil prices......Rp 10.000 per kg
- Catalist prices (NaOH)............$ 0,22 per Kg
- Methanol prices......................$ 0,46 per Kg
- H2SO4 prices.........................$ 0,35 per Kg
- Energy prices..........................Rp 4.500 per liter
- Glycerol prices........................$ 26,15 per liter
 Potensial convertion of kapok seeds oil become
biodesel in high capacity of production.

22. Feasibility study
 For the feasibility study, we still do the
calculation but we get the value from our
calculation is :
 ROI : 104 %
 POT : 0,89 year
 POS : 32,31 %
 BEP : 10,61 %
 SDP : 5,64 %
 i Factor : 28,36 %

27. Optimization
 Composition of methanol and catalist of
NaOH (reaction temperature sets in 55 C – 60
C)
 Stirring process
 Heating temperature
 The purity of catalist
 Convertion of biodiesel reaction.
