Abstract

To save energy nowadays is recommended to switch to renewable energy sources. In Indonesia, solar energy is abundant, so PLTS is made. The supply of PLTS is expected to reach maximum use. However, solar panels have many obstacles such as variations in temperature and sunlight intensity, MPPT systems are needed to find the maximum power point of the solar panels. Unfortunately, in Indonesia, the sunlight of short duration with the ideal irradiation time that can produce electricity from solar panels is 4 to 5 hours per day, so a PLN supply is still needed to support the continuity of the power supply. Because two sources are used, there is a problem where the load needs high continuity during power switching, so STS (Static Transfer Switch) is used for very fast power switching. Simulation results, when using EMR (Electromechanical Relay) the power transfer process takes 50ms or 5 cycles while STS takes 2ms or ¼ cycles. With very fast response to STS, sensitive equipment is kept safe from power quality disturbances such as voltage sag and voltage swell.

Abstract

In production, packaging is an essential factor. Especially if the product is in the form of food, the function of the packaging is to protect it from sunlight, dust, and other damage. There are still many who use the manual method in the home industry. The process still requires many human resources.For this reason, the design of an automatic powder packaging device based on the Atmega 16 microcontroller was made. This tool serves to package flour (flour, sugar, and coffee) packaged automatically using a microcontroller as the brain of the device. The initial packaging method was to put the powder in each container. Then the powder will come out automatically according to the input of the type of powder and the desired weight of the operator via the keypad. Then the powder enters the dose that Loadcell has installed as a weight detector displayed on the LCD. After the weight reaches the set point, the powder will enter the package. The package that has been filled with powder will be pressed using a sealer. From the tests carried out, the percentage of success reached 70%.

Abstract

Water is one of the human needs. There are many types of water that are needed and good for humans, including alkaline water and acidic water. Alkaline water has benefits, one of which is to improve the immune system. While acidic water has benefits, one of which is as an antiseptic or disinfectant. There are obstacles for this water-producing device, which is that it is still very expensive for water-producing equipment and it is still very rare to use solar energy as a source of electricity. The author will make a device that produces alkaline water and acid water with solar energy as a power source using a Solar Cell Module (MSS). Water ionizer is an instrument to ionize water and its mineral content by using water electrolysis method, so that the water ionizer can produce alkaline water and acid water. The tool in this study used a 20 WP solar cell module that stores electrical energy in a 12V 7AH battery. Other components used are the container water ionizer, PH4502C pH sensor, INA219 current sensor, DS18B20 temperature sensor which is connected to a microcontroller. The value of the current produced depends on the TDS of the water used, if the TDS of the water is high, the current generated is also high. Changes in pH obtained in this study with a maximum pH increase of 2.60 and a maximum decrease of 9,30 pH.

Abstract

In chopping Rebung for the home industry, they still use conventional methods and lack the application of technology. This, of course, causes the productivity and quality of the home industry products to be less than optimal. Productivity is influenced by several factors, including requiring workers to be more careful so that it requires a lot of concentration, worker fatigue, which makes it less optimal in using time, and the workers' speed. Therefore, the primary control system was made an automatic Rebung chopper based on the VFD with Arduino Uno. The 3-phase induction electric motor is used as a prime mover for chopping blades and control using VFD (Variable Frequency Drive). For the critical system, use a spring and open the pressing tube's lid using a servo motor and the buzzer as a monitoring medium. The test uses VFD to adjust the rotational speed of the electric motor. The test results show that at a frequency of 20 Hz with a speed of 147.8 rpm, it produces chops with a length of 3 cm in 2 minutes 54 seconds. At a frequency of 35 Hz with a speed of 221.2 Rpm, it produces 2 cm chunks in 1 minute 53 seconds. At a frequency of 50 Hz with a speed of 260.1 Rpm, it produces 1 cm chops in 1 minute 5 seconds. If chopping is done manually, it takes 5 minutes with an average length of 2 cm

Abstract

The shopping center switchboard system consists of several parts: a 20 kV cabinet to a 20 kV to 380 V step-down transformer, which is then provided to the user to control the newly upgraded LVMDP (low voltage main switchboard). Before distributing to users, they need to pay attention to the fixed power factor of the capacitor bank. Lack of an exemplary power factor will cause an inductive load on the capacitor bank, high temperatures due to high loads will damage the capacitor bank. A switchboard safety automation technology with a microcontroller control system has been proposed to complete this research. Microcontroller control system for switch safety includes Microprocessor (Arduino Nano), light sensor (LDR), temperature sensor (LM35DZ), LCD 16x2 I2C, actuator (fan, buzzer, three-phase network disconnect switch relay), switch (5 VDC relay), ADC As data input. The working principle of the microcontroller is: if the LM35DZ sensor detects the specified temperature, an alarm will be triggered, while the LDR sensor detects a spark, the alarm will be triggered as a danger warning signal and cut off the power grid. Equipment designed to prevent switchboard safety caused by high temperatures or sparks can prevent fires.
