| dc.description.abstract | Calcium lactate (C6H10CaO6) ia an organic salt derrived from lactic acid.
Calcium lactate is a GRAS (Generally Recognized As Save) compound so that
calcium lactate has wide applications in industry, health and food.
The raw material used in this pre-factory design is breadfruit. The process
starts with the raw material preparation stage. At this stage the breadfruit will be
cleaned and then shredded. The second stage is the hydrolysis process where the
breadfruit will be hydrolyzed with the help of catalyst HCl in the hydrolysis reactor
to produce glucose. The hydrolysis reaction condition is at 30°C with 1 atm. The
third stage is the separation process to separate glucose from breadfruit that is not
hydrolyzed using a centrifuge. The fourth stage is the neutralization process where
the HCl content in glucose will be neutralized using NaOH to produce NaCl. Then
NaCl will be separated from glucose using Reverse Osmosis Membrane. The fifth
stage is the bacterial breeding process where 10% glucose will be used to breed
Lactobacillus delbruckii bacteria in the Culture Tank. The breeding process lasts
for 9.31 hours with a temperature of 45°C. The sixth stage is the glucose
fermentation process to produce calcium lactate in the Fermentation Reactor using
Lactobacillus delbrueckii bacteria for 9.31 hours at 45°C and 1 atm pressure. The
seventh stage is the sterilization process where the calcium lactate will be sterilized
by heating the calcium lactate to 82°C to kill the bacteria. After neutralized, the
calcium lactate is flowed to Decanter to separate the water-insoluble components
from the calcium lactate. Then the water content in calcium lactate will be removed
using an Evaporator. After the calcium lactate becomes powder, the calcium lactate
product is stored in the production warehouse
The preliminary plant design of calcium lactate production plant from
breadfruit using fermentation process has a capacity of 3,200 tons/year and
operates for 330 days a year. The plant is planned to be established in Tugu
District, Semarang City, Central Java Province with a plant area of 13,900 m2.
The water requirement for this plant is supplied from Beringin River as much as
13,140.199 kg/hour. The planned form of business entity is a Limited Liability
Company (PT) with a total workforce of 120 people.
The results of the economic analysis of this calcium lactate manufacturing
plant from breadfruit are as follows:
- Total Investment Capita : Rp 361,098,170,592,-
- Total Production Cost : Rp 115,351,363,803,-
- Sales Proceeds : Rp 230,397,785,088,-
- Net Profit : Rp 79,782,169,950,-
- Profit Margin (PM) : 49,43%
- Break Even Point (BEP) : 47,41 %
- Return on Investment (ROI) : 22,09 %
- Pay Out Time (POT) : 4.53 Years
- Return on Network (RON) : 36,82 %
- Internal Rate of Return (IRR) : 22,95 %
From the results of the economic aspect analysis, it can be concluded that
the calcium lactate manufacturing plant from breadfruit is feasible to establish | en_US |
