Abstract
Poultry industry is an agricultural sector which contributed to the growth of economy
in Malaysia. According to the Department of Environment Malaysia 's reports, received
a total of 1082 cases concerning odor problems and emissions in relation to the livestock
farms. The pattern indicated a rise in odor problems per year. This is because manure
itself will produce bad gas that can lead to the bad illness. Poor management of the
manure is alleged to be the source of the problems. The odor comes from the chicken
manure attract the flies and cause problem to the surrounding area. The main purpose
of this project is to mitigate the problem by designing a system that can eliminate the
odor of the chicken farms. Moreover, this project also outlined the design process of
making fertilizer from the chicken manure, followed with the development of the most
efficient and rapid composting soil from the chicken manure. The project is designed
for smaller production to fit the capacity with a total of 450g of chicken manure which
equivalent to 3 chickens. The design of the project mainly consists of 3 components
which is conveyor, sheet metal slab and rotary dryer. The design is created using
SolidWork software which include the drawing of each parts, components assemble,
bill of materials, dimensions and also the stress strain analysis of the critical components
is generated using the software. In order to obtain the final product of the chicken
manure odor elimination system, the raw materials such as sheet metal, slotted angle
steel, steel rod and others is undergone the manufacturing processes of bending, cutting,
drilling, welding, labelling and painting. The stress strain analysis of the critical
components showed that the components are safe to work in the system as the Factor of
Safety is above the allowable limit of 1.5. Not just that, the motor selection study
resulted in a motor torque of at least 11.95 mNm or greater. In addition, the system
analysis on energy required to dry out a total of 450g of chicken manure resulted in a
total of 795.28kJ. The power requires for the system is 9.72kWh to work 3 hours a day
for 30 days in a month. The cost to produce the drying machine unit for chicken manure
is RM246.88. Project testing is executed following the procedures to validate the
reliability and effectiveness of the chicken manure odor elimination system.
