Abstract

Sumber tegangan searah didapat melalui rangkaian penyearah gelombang penuh satu fasa tidak terkendali dari sumber tegangan jala – jala PLN sebesar 220 Volt. Pemasangan kapasitor sebagai filter dengan nilai atau jumlah yang cukup besar dapat menyebabkan bentuk gelombang arus masukan menjadi tidak sinusoidal (terdistorsi) akibat dari harmonisa yang muncul sedangkan tegangan masukan dari jala – jala PLN berbentuk sinusoidal. Perbedaan bentuk gelombang tegangan dan arus masukan yang terjadi ini dapat berpengaruh pada nilai faktor yang dihasilkan. Berdasarkan masalah ini dibuatlah suatu penelitian mengenai perbaikan faktor daya menggunakan rangkaian Interleaved Boost Converter yang difungsikan sebagai rangkaian Power Factor Correction (PFC) dan regulator tegangan dengan metode pengaturan menggunakan logika Fuzzy. Rangkaian Interleaved Boost Converter ini dibuat bekerja pada kondisi Discontinues Conduction Mode (DCM) agar apapun beban yang dicatu pada rangkaian akan membuat sistem bersifat resistif. Sehingga diharapkan bentuk gelombang tegangan dan arus masukan sama yang akan menghasilkan nilai faktor mendekati nilai unity. Hasil dari penelitian ini adalah rangkaian Interleaved Boost Converter yang sudah dapat difungsikan sebagai rangkaian Power Factor Correction dan juga sebagai regulator tegangan. Nilai Faktor daya yang dihasilkan adalah sebesar 0.93 dimana jika dibandingkan dengan nilai faktor daya dari Power Supply Swicthing 48V sebesar 0.90 sudah jauh lebih baik.

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 vital capacity value of the lungs is very influential with the health of the human lungs because with the results the value of the vital capacity of the human lung can be diagnosed as normal or abnormal of the lungs. This study aims to make a means of detecting respiration gas flow rates in humans using an arduino uno-based YF-S201 flow sensor. From the results of data analysis of respiratory gas flow in adult male breathing with ages (20 years - 30 years), (30 years - 35 years), (35 years - 45 years) and (45 years - 50 years) as many as 15 users. there is an error of 3.86%, the value is generated from comparing the output of the equipment made by researchers with other tools of the brand Spirolab with as many as 15 users of different height and age. From 15 different users there are 2 users with abnormal lung conditions and 13 other users with normal lung conditions. The result of this error occurred because of the 15 users who were less relaxed when exhaling and breathing.

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

The automatic home control system is currently one of the interesting discussions to be developed, there are many innovations that can be done to facilitate human work in controlling the tools contained in the house. One of them is the use of android for controlling the tools that are inside the house and MIT Invertor is a software for making android applications with a design designed according to the design of the house. The control of home appliances / electronic devices that are often used nowadays are many that are integrated with mobile / smartphone devices. This study aims to design an automated home control system that can facilitate human activities in the home such as turning on and off lights and other electronics by using Android devices as a controller and using the HC-05 bluetooth module as a communication tool. The results of this study can show that the Android application can replace the function of the switch for controlling home appliances.

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

Abstrack - Optimal temperature and humidity greatly affect the growth of oyster mushrooms. Cultivation of oyster mushrooms in kumbung is an attempt to control the optimal temperature and humidity for fungal growth. Periodic manual watering was felt to be less effective in controlling temperature and humidity in mushroom kumbung. Current technological developments provide the potential to create automatic control systems to control temperature and humidity in mushroom kumbung. Therefore, in this research, a controller is designed to control temperature and humidity in kumbung mushroom automatically based on a microcontroller. This shows that the control system designed is able to control the temperature and humidity in the mushroom kumbung automatically
