BIODIESEL FROM KAPOK seed OIL By Group 8 Agus Aktawan (Chemical Engineer) Bram Styawan (Electrical Engineering) Humaidi Usman (Mechanical Engineering)

Background... Total world oil reserves is going down Total World Energy Demand is going up The increasing of Environment destruction Increasing in unemployment Supporting “Green Energy” Solution in renewable energy

Objectives Growing awareness of the importance of environmental Optimizing the usefull of renewable energy Increasing the public knowledge and skill in renewable energy Motivating people to prefer using the renewable energy

The Process of making biodiesel

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.

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.

Oil Pressing Diagram Kapok seeds are from Pandaan, East Java. Screw press The screw pressing tools used diesel motor as a power and this tools can optimally press the kapok seeds. The pressing process is continue and produce oil and waste. Oil This product is like crude oil that still contaminate with a few of kapok seeds.

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.

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).

Esterification and Transesterification Process

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.

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 %
