Abstract

The unidirectional voltage source is obtained through an uncontrolled 220 Volt single phase full wave rectifier circuit. Installation of large amount capacitors as a filter affect input waveform. Due to the harmonics distort sinusoidal input voltage from the PLN grid. The difference in voltage waveforms and input currents that occur can affect the value of the resulting factor. Based on this problem, a study was made on theimprovement of power factors using a series of Interleaved Boost Converter which functioned as a series of Power Factor Correction (PFC) and voltage regulators with a setting method using Fuzzy logic. This Interleaved Boost Converter circuit is made to work in the condition of the Discontinues Conduction Mode (DCM) so that any load that is supplied to the circuit will make the system resistive. So, it is expected that thevoltage and input current waveforms will produce a factor value close to the unity value. The results of this study are the Interleaved Boost Converter series that can be used as a Power Factor Correction circuit and also as a voltage regulator. It improves power factor from 0.9 to 0.93.

Abstract

The charging device usually uses a transformer and a diode bridge. Charging the battery is called direct charging. Because it does not have a safety for the battery it can cause heat to the battery. But over time, this is no longer effective, this work can be done digitally using a microcontroller.. However, this tool is still not perfect because at the time of testing it cannot be set, sooner or later, the charging is to cut time efficiency and there is no indicator that states that the charging is full or not. Therefore, based on the description above, the researcher aims to make a smart charging accumulator based on the Arduino Uno microcotroller that is smarter, more efficient and can be used easily, with the advantage of having a tap changer on the transformer that functions as a regulator of the output voltage. as desired and piezoelectric alarm as an indicator if a full charge or there is a problem with the equipment itself.

Abstract

Technological sophistication is growing in various ways, for example in the security system of an object. Basically, the security system of an object is done manually which is less practical than today's technological systems. One application of the security system is for locker safety. Therefore, to overcome the security system in the locker, the solution is to create a security system that uses ESP32-CAM as an Internet of Things (IoT) android-based microcontroller for the android interface for the security system in the locker and when someone forcibly opens the ESP32-CAM module it will take a photo. the person to notify the user about the current state of the locker via the telegram application on android.

Abstract

Security at the door is very important for everyone. because the door acts as access to enter or exit a private room. Therefore, the key as a door security plays an important role in implementing the security system. With the frequent occurrence of key loss and also the rise of increasingly sophisticated crime rates in breaking into or destroying conventional keys, it becomes a thought for the author to develop a security system that is more private in nature. That is by using an application that is expected to be a security in the form of a password which will certainly be more profitable. The design of this tool is made with Arduino as a processing center and a servo motor to function to move the doorlock. The next stage Arduino will give a command to the servo to open the door. Only certain people who have access passwords can open doors in rooms that use voice recognition. Meanwhile, those who do not have an access password will not be able to unlock the door in the server room. So that the design of a smart door lock tool that uses Arduino-based voice recognition will provide a more computerized level of security and access

Abstract

The human body requires sufficient oxygen levels for daily life, so it is important for humans to maintain oxygen levels in their bodies. Good oxygen saturation will facilitate the distribution of substances in the body, red blood cells carry oxygen from the lungs and are distributed throughout the body. It is very important for humans to keep oxygen within normal limits. Excess oxygen in the blood or hyperoxaemia: above 120 mmHg. The normal limits for oxygen levels in human blood are between: 75-100 mmHg. Lack of oxygen or hypoxaemia is less than 75 mmHg. A blood oxygen level below 60 mmHg indicates a very severe blood deficiency and you need supplemental oxygen. The design of an oxygen saturation monitoring tool through the Thingspeak server with a max 30100 sensor based on nodemcu 8266 aims to make it easier to monitor oxygen levels in the blood so that it can take early anticipation to avoid unwanted things. The design of this tool is equipped with monitoring using a Thingspeak server that can be connected to the internet or WIFI so that we can do it when we are there. This blood tool is designed using a MAX 30100 sensor as an oxygen detector which is clamped on a finger and then connected to NodeMCU 8266. After waiting for a while the sensor detects oxygen levels < 80% >, 100% NodeMCU 8266 sends data to the LCD and Thingspeak. On the Thingspeak server we can observe the oxygen levels in our bodies. We can use this tool far away so we don't need to go to the hospital or health center to measure the oxygen saturation in our bodies.

Abstract

Heart health is an important thing to monitor, because the heart is an important vital organ and is prone to disturbances, especially for the elderly. Such as stroke, arrhythmia and other heart diseases. Usually a heart rate detector is only owned by people who work as health workers and health agencies, and if someone who has heart disease such as stroke and arrhythmia wants to check his heart health, he must come to a doctor or health agency. Therefore, a measuring device and monitoring of heart rate are made on a regular basis. This heart rate measuring and monitoring device is based on a microcontroller and android with a periodic database-based monitoring system. By using the MAX 30100 sensor which has an average error of approximately 3% with a difference value of more than 3 bpm with existing standard measuring instruments.
