Abstract
This study describes an automated Kuih Loyang’s simulation machine that was
developed to replace the manual process and thereby boost Kuih Loyang production.
The pneumatic cylinder and Arduino UNO were utilised by the machine to accomplish
the automatic system. The machine is programmed to do the dipping stage, which
includes shaking parts of the mould frame to remove all of the Kuih Loyang from the
mould. It was discovered to be capable of properly completing the tasks coded in the
Arduino IDE. This research compares the vibration value of the simulation machine
to the manual machine in the factory by measuring the vibration produced by the
shaking of the mould frame. As a result, a system capable of measuring the
acceleration of the mould frame during shaking has been created to measure the
vibration in terms of acceleration. The MPU6050 was used to measure the acceleration
in terms of the metre per second squared. The device takes raw data from an
accelerometer mounted on the mould frame and processes it using an Arduino UNO
controller to compute gravitational values. The gravitational values then minus with
the offset values to obtain the actual data for the acceleration in g unit. Next, the
machine shaking is analysed by determining the frequency and amplitude of the mould
frame. Data from the Arduino is serially delivered to the monitoring system, where it
is saved in an excel file. Then, in Excel, the Fast Fourier Transform (FFT) is used to
convert the time domain G-values to the frequency domain. After executing the Fast
Fourier Transform (FFT), the frequency and amplitude are obtained. Excel was used
to create a graph of acceleration versus time and frequency versus amplitude.
According to the statistics, the simulation machine shakes three times, resulting in
maximum accelerations of 1.01g, 0.79g, and 0.57g, while the manual machine at the
factory shakes only once. The manual machine's maximum acceleration at the factory
is 1.03g. The simulation machine's highest frequency is 79 Hz followed by 10 Hz,
while the manual machine's highest frequency is 12 Hz followed by 53 Hz. This
demonstrates that the simulation machine, like the manual machine, was able to
remove all of the Kuih Loyang from the mould during the dipping stage. This study
successfully demonstrates this.
