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

Landslide is a natural disaster caused by activities or processes that disrupt the balance that causes the movement of soil and rock masses from high areas to low areas. To avoid high losses due to the disaster hazard, efforts are needed to minimize one of them by mapping areas of potential landslide disasters. This study aims to obtain the zone of potential landslide disaster area based on the data of slope class, rainfall and regional geology of the research area. The results of processing based on DTM (Digital Terrain Model) obtained slope classes, namely flat (0° – 2°) 19.36%, undulating slope (2° – 4°) 30.65%, undulating-rolling slope (4° – 8°) 19.72%, rolling-hilly slope (8° – 16°) 16, 4 %, hilly-steeply dissected slope (16° – 35°) 8.03%, steeply dissected-mountainous slope (35° – 55°) 4.58%, and mountainous slope (>55°) 1.27 %. Based on the analysis of slope class data, annual rainfall data and regional geological maps, there are potential landslide areas with areas marked with orange to red color symbols with a total area of ​​0.866 ha with hilly-steeply dissected slope (0.501 ha), steeply dissected-mountainous slope (0.286 ha) and mountainous slope (0.079 ha). The rainfall is 2800 – 3200 mm/year, and the regional geology is dominated by tuff.

Abstract

This study aims to determine the effect of holding time artificial aging on the hardness and microstructure of Al-2024. This study used a specimen in the form of Aluminum 2024 series which was heat treated at a temperature of 500°C for 60 minutes, then quenched with a cooling medium in the form of water. Subsequently, it was reheated with variations in holding time, namely 3 hours, 5 hours and 7 hours with a temperature of 190°C. Then the specimen is slowly cooled to room temperature. The results of the chemical composition test using Spectromax showed the percentage of Al was 90.6% and Cu was 5.90%. The results of the hardness test using the Rockwell Hardness Tester obtained a hardness value without heat treatment which has a hardness value of 71.4 (HRB), a hardness value after quenching of 66.9 (HRB). The highest hardness value is found in heating with a holding time variation of 5 hours with a temperature of 190°C, the hardness value is 84.6 (HRB) where the hardness value at a holding time of 5 hours has increased by 8.48% from the hardness value of the material without heat treatment. Microstructure testing showed that the Al-Cu material after the artificial aging process at a holding time of 5 hours had a precipitate phase (θ) with a higher amount and the Al-Cu grain boundaries tended to be more dense and regular. This means that the material that has been treated with artificial aging has precipitated deposits or the formation of a second phase which causes the material to be harder and have better mechanical properties.

Abstract

Bioprinting has grabbed attention in recent years. To study the behavior of living organisms on the basic level, bio-medical engineers have introduced bioprinting as a cheap and affordable method to construct and fabricate tissues using cells and positioning methods along with cell culture techniques. The applications such as the use of perfused three-dimensional (3D) human cardiac tissues for toxicological research, drug testing, and screening or personalized medicine. Moreover, it helps to develop in-vitro tissue test systems, with which one can explore basic cellular behaviors, disease progression, and treatment options. A standard thermal inkjet printer was modified to accomplish the bioprinting. Cell viability was determined. We made two types of printing 3D and 2D. The 3D printing is much closer and mimics the in vivo condition and allows more cells to be printed per unit space.
