Abstract

As technology develops in today’s age, there are many radio equipment easily found in the market. Certainly, there is a stereo decoder module inside a FM radio receiver which operates to return radio signal that previously was modulated and broken apart into stereo audio signal (L+R) and (L-R). There are many stereo decoders already presented inside FM radio receivers. Based on this premise, there is a problem that can be studied, which is how to design a decoder stereo in a stereo FM radio receiver that functions as the demodulation in stereo FM radio and operates to release L+R audio signal to a receiver radio. Therefore, it needs a signal demodulatorof encoder stereo that converts L and R audio signal. Based on the testing result, it showed that sideband frequency from the result of DSB-SC demodulator process, which was produced through R and L channels, still had frequency value differences with average percentage of 1.416% out of the expected frequency value. This was due to the frequency oscillator from the generator function.

Abstract

Parallel series is very suitable to be used to overcome the ups and down of voltage caused by the supply of sunlight to the solar cell. The series circuit can be used to overcome the lack of voltage on the solar cell, while the parallel circuit is used to flow larger currents with a constant voltage when the supply of sunlight on the solar cell is at its maximum. Solar cell as converters of sunlight into electrical energy in the form of DC voltages, which are connected in parallel series by utilizing relay contacts that are controlled using atmega 16 microcontroller, where the voltage generated by the solar cell in the sensor uses a voltage sensor. Switching regulator as lowering the voltage over solar cell for battery charging. The test results using a series of series and minimum lighting produces a voltage 14,8 Volt, parallel circuits and maximum lighting produces a voltage of 20 volts, and a combination of parallel-series under moderate lighting conditions produces a voltage of 23.3 VoltDOI : https://doi.org/10.26905/jeemecs.v3i2.4731

Abstract

Parfume is a tool that we often use in our daily life. The fragrance of the perfume we use is also diverse to prevent user boredom. In addition, the smell of perfume is also a match for the consumer itself. The rapid development of technology lately indirectly affects the changes in the broader community. The many sophisticated inventions evidence the development of this technology.Along with developing this technology, the equipment can be created to facilitate and provide production speed. In other words, it can increase the quality and quantity of producing goods for the users of these tools. With these technological advances, it can be used to make perfume-ingredients mixing tools to manufacture one type of perfume using a microcontroller. The test results of this tool after manual settings are obtained automatically on measuring cup 1 containing 19cc, cup 2 containing 10cc, cup 3 containing 19cc, cup 4 containing 18cc, and cup 5 containing 29cc. With an average error rate from testing the entire system of 4,8%, the system is declared to be able to work well

Abstract

The river cleaning system is very concerning because of the amount of garbage that accumulates in the river, causing odor, dirt and flooding. In this regard, the idea arose to create a miniature river cleaning tool that is placed in the river or sluice channel. The way it works is that the tool is installed in the river or sluice channel, the tool is like an iron spoke. Then a sensor is installed in front of the iron spoke and there is also a stepper motor that is tasked with rotating the iron spoke. If there is garbage that blocks the sensor, the sensor gives a signal to the Arduino, then the Arduino gives a command to the motor and the motor rotates the iron spoke to lift the garbage from the river and throw it into the trash can that has been provided. Based on the test results, when the garbage sensor is not blocked by garbage, the stepper motor turns off and does not rotate. If the garbage sensor is blocked by garbage, the stepper motor turns on and rotates clockwise.
