Abstract

At first, robots were created to replace routine human work, requiring a high level of precision, and also to replace humans in dangerous situations. Robots that have the ability to maintain self-balance are called Self Balancing Robots. The Self Balancing Robot is the result of the development of an inverted pendulum model which is positioned on top of a wheeled train. The robot is controlled using a remote control using NRF 24L01 which can be controlled remotely. And to find out the situation in running the robot which is controlled from the remote using To detect the tilt angle of the robot, the MPU6050 sensor is used which is a module that integrates three sensors, namely the gyroscope and accelerometer on three different axes.

Abstract

An Electrocardiogram (ECG) signal results from recording the heart's electrical activity. Currently, diseases originating from heart abnormalities still dominate the world. Therefore, doctors need to find an ECG signal that is free from noise, this cleaning process is called denoising. The denoising methods commonly used are the wavelet transform method, and the Fourier transform method. Testing was conducted on ECG signal data with abnormalities in Apnea with RR intervals filled with noise, making the QRS complex difficult to identify. As a result, the Discrete Wavelet Transform (DWT) method produces the best form of reconstruction, resembling the initial ECG signal, while the Fast Fourier transform (FFT) method produces the best signal-to-noise ratio (SNR) for the denoising process. So, we get a superior FFT method in the ECG signal denoising process.

Abstract

Gas is a molecule that is unbound, shapeless, invisible, and can transform into liquid or solid forms. Liquified Petroleum Gas (LPG) has become a part of people's lives, especially in cooking, and there are many benefits to using LPG. However, there are dangers posed by leaks of LPG gas that can lead to house fires. Improper installation of regulators is one such risk. Preventive measures against fire hazards caused by leaks can be anticipated by using the design and construction of an Early Warning System for LPG Gas Leaks based on the Internet of Things (IoT) using the Blynk application with the NodeMCU ESP8266 module. This device is equipped with an MQ-2 sensor, a relay, a 12V DC fan, and the Internet of Things. The system works as follows: when the MQ-2 sensor detects the presence of LPG gas, the relay turns on the fan, which will remove the gas from the vicinity of the open flame on the stove. The system can be monitored through the Blynk IOT application, which also provides notifications

Abstract

Infant development and growth at the age of 0 to 1 year. Babies are easily affected by malnutrition or, if parents ignore the development and growth of the baby. Generally, parents will take their babies to Posyandu or Midwives to have their weight weighed and the length of the baby's body measured. At the time of measuring the baby's body weight and length still using separate and manual measurements. Therefore we need a weighing device that is able to measure the baby's weight and baby's length simultaneously. Then an "Arduino Uno-Based Baby Weight and Length Weighing Device was made by Combining the HC-SR04 Ultrasonic Sensor and the Weight Sensor (Load Cell)" to simplify the process of measuring the baby's weight and length simultaneously and recording the results of these measurements. The benefit of making this tool is that it helps parents to know the growth and development of their babies aged 0 to 1 year. And the purpose of making this tool is to measure the baby's weight and length simultaneously, which in general the process of measuring the baby's weight and length is still not automatic, and still uses analog or digital scales but there is no tool that can measure automatically and simultaneously in the process of measuring the baby's weight and length. From here we submit a research proposal in which the results of this research proposal are expected to contribute well as a first step in our research so that in the process of designing the tool it can work well and be useful for parents and medical personnel

Abstract

As a country with a tropical climate, Indonesia stands out as a land rich in various types of animals and plants. The diversity of climates and environments provides fertile habitats, enabling the survival of various species that adorn Indonesia's natural beauty. To fulfill the desires of subtropical plant lovers whose hobby is agriculture, researchers have the idea of creating a research automatic planting system that can be used to grow subtropical plants in urban areas. The ESP32 acts as a monitoring device that produces vital information regarding environmental conditions, such as soil moisture, water acidity levels, and feed supplies in a system. Through this monitoring, research can collect relevant data to analyze conditions and optimize these factors. The data obtained will be processed and analyzed through daily development comparisons. The existence of intelligent systems, such as monitoring water pH and humidity, providing fish food, and regulating the water content in ponds and hydroponic growing media, can make it easier for those who want to develop farming and fish farming hobbies in urban areas where land is limited and busy with activity.

Abstract

This research aims to design and build a monitoring system capable of measuring voltage, current, and frequency on 3-phase electrical panels for audio-sound systems. This system uses an ESP32 device as a microcontroller and Ubidots as a cloud platform for real-time data visualization and storage. Equipped with a PZEM004t as a voltage, current, and frequency sensor, this system provides accurate and real-time monitoring of electrical parameters. An analysis was carried out on the ability of this system to be accessed remotely via the network, as well as the integration of notifications via the Telegram application for direct notification of disturbances in the electrical panel. Testing was carried out by comparing this system with existing electrical panel boxes as well as through observation and assessment by five sound engineers to evaluate the system's performance in monitoring voltage, current, and frequency accurately and stably. The test results show that the system is capable of measuring and monitoring electrical parameters well, providing useful information for the maintenance and management of electrical systems, as shown by the results of the average map test error on the parameters voltage (0.4%), current (10% and frequency (0.6% and in usability testing, a percentage score of 97.5%. The implementation of this system is expected to increase the operational efficiency and reliability of the audio-sound system.

Abstract

This Arduino-based automatic metal and non-metal waste sorting tool is designed to sort waste, making it easier to recycle waste. The main components of this tool include Arduino (as a tool control system), proximity sensor (as a metal scrap detector), servo motor (as a driver to isolate metal scrap) and LCD to display the type of metal scrap. In terms of waste sorting, the Proximity sensor will detect waste. If the waste is detected as metal waste, the servo motor will rotate to the right and direct the waste to a special metal waste bin. The LCD screen will display the type of metal waste. If the proximity sensor does not detect non-metal waste, the servo motor will rotate to the left and direct the non-metal waste to a special non-metal waste bin. This type of waste sorter is very helpful in reducing waste because it can be processed according to the type of waste.

Abstract

Seluruh data pemilu di Indonesia diolah dan disimpan oleh Komisi Pemilihan Umum Republik Indonesia-KPU dengan menggunakan Sistem Informasi Rekapitulasi Pemilu (SiRekap). Sistem SiRekap mematuhi undang-undang terkait, dan semua datanya ditangani dan disimpan di pusat data Indonesia. Pemilu rentan terhadap berbagai macam ancaman teknologi, mulai dari masalah keamanan siber tradisional, seperti peretasan dan pelanggaran data, hingga bentuk manipulasi yang lebih canggih, seperti deepfake dan disinformasi yang dihasilkan oleh AI. Pelaku ancaman dapat mengeksploitasi kerentanan dalam infrastruktur pemilu, dengan menargetkan sistem pemungutan suara elektronik dan basis data pemilih. Langkah-langkah pencegahan keamanan siber sangat penting untuk melindungi pemilu dari serangan siber yang selalu berubah, seperti: tanggung jawab bersama atas keamanan siber, menggunakan keamanan siber untuk mendapatkan keunggulan, kebutuhan hukum dan peraturan akan keamanan siber, praktik terbaik untuk keamanan siber, contoh- contoh keamanan siber di dunia nyata, cita-cita pilihan bagi perusahaan dan institusi. Pemerintah mempunyai peran penting dalam menjamin keamanan siber. Peningkatan keamanan siber akan sangat bermanfaat dalam mencegah kebocoran dan peretasan. Dengan harga yang wajar, sistem pemilu itu sendiri dapat diperkuat secara signifikan dalam hal keamanan.
