Abstract

Nowadays in Malaysia, the livestock industry has become the increasing demand over the past few years. Like agriculture, livestock is also a growing business that can help local farmers to generate their income. Thus, an economic and practical chopper machine for livestock feed is necessary to fulfil this demand. The machine is driven by an AC powered motor (1400 rpm, 1 Hp). It is divided into five major components, which are the fodder inlet, fodder outlet, power unit, cutting unit and frame stand. For safety reason, a cover made by clear acrylic Perspex were built in front of the blade to prevent any injuries. The machine structure is reasonable and practical as it is supported by four lockable wheels and handle for easy movement. Time taken to finish the chopping process will be analyzed for both methods. Three different weights of fodder will be used. For 500g, 1000g and 1500g of weight, average production time taken by machine is 15s, 33s and 42s respectively. While conventional method is 240s, 400s and 640s respectively. The percentage decrease of production time was calculated to evaluate the performance. Based on the result obtained, it shows that by using the chopper machine, it can help to reduce the production time to produce the chopped fodder compared to the conventional method. For weight 500g, it reduces the production time to 93.75%, for weight 1000g to 91.75% and lastly for weight 1500g to 93.44%. Hence, the chopper machine is practical, flexible and cost effective to use for chopping fodder.

Abstract

The demand for poultry products is seen increasing from year to year. This is a good thing for local chicken entrepreneurs. But the task of plucking chicken feathers is time-consuming and tiring. The production of machines to help simplify the process of removing chicken feathers is seen as a necessity for these small and medium industrial entrepreneurs. This is why we focus on producing chicken feather retractor machines (CFRM) that are capable of processing up to five chickens at once. This machine is portable and easy to move around and supported by four wheels that can be locked to ensure stability. This machine can perform effectively to remove feathers using friction concept between the chicken and the plucker fingers rubber which attached around the drum. The machine also environmentally friendly by filtering the feather from scattered everywhere and only allow water to come out. The result shows that this machine operates under the motor powered with 115.13 rpm with the rotating plate area is 0.166 m2 and drum volume of 0.158 m3. This machine managed to remove the feathers of up to five chickens within 30 seconds to 60 seconds.

Abstract

This project work is on design and fabrication of a plastic compressor machine to compress plastic waste. The objective of this project is to help to reduce plastic waste mostly from domestically usage and turn into a paving brick that can be uses as decoration in a mini garden or walkway. This plastic compressor machine works using a modified old conventional oven to melt shredded plastic waste in a mould and let the melted plastic cooled and turned to a paving brick. The temperature to melt the shredded plastic waste of 450 grams is 250 degrees Celsius in 1 hour. The machine fabricated using recycled materials, which makes it cheap, easy to maintain and affordable.
