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.

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).

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 %
