Abstract

Electromyography (EMG) instrumentation is essential in generating electrical signals from skeletal muscles. EMG sensors are helpful in various cases requiring the detection of human muscle contractions, neuromuscular disorders, and rehabilitation. EMG instrumentation is divided into two parts, namely, the analogue part and the digital part. The EMG instrumentation design comprises a digital-to-analog converter (DAC), instrumentation amplifier, filter, and analog-to-digital converter (ADC). Meanwhile, in digital signal processing adopting the Discrete Wavelet Transform (DWT) method, frequency analysis using DWT has proven superior. It is used in various research and has exceptionally detailed coefficient features for classifying neuromuscular disease signals. Therefore, this research aims to design analogue and digital EMG instrumentation and identify features in the form of detailed coefficients. The data used are two Physionet signals from the anterior tibialis body with myopathy and neuropathy disorders. The results obtained for EMG analogue instrumentation provide the expected results until they reach the filter component stage. The resulting signal forms a block in the filter component, different from the initial EMG signal. Meanwhile, the DWT decomposition results are of the Daubechies4 wavelet type with the highest level 17, which has a high detail coefficient at low frequencies, high dilation and the result of a mixture of neuropathy and myopathy EMG signals, or in other words, at low energies, this result is by the DWT theorem. Determining the efficiency of the DWT detailed coefficient feature requires further study with the same signal subject. The DWT features obtained can then be developed for various needs in EMG signal recognition.

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

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.

Abstract

Air conditioners are among the technologies that have been increasingly common, as time has gone on, from personal comfort to room comfort. A multi-story building is one location that requires air conditioning. This is because the structure's air pressure will rise until a certain level, making the temperature too low, so air conditioning is necessary to maintain a comfortable temperature. Similarly, in tropical areas where the temperature exceeds what is reasonably comfortable. However, the current air conditioner technology has the potential to harm the environment. Since Freon, which is used in it, can pass through the ozone layer. Eventually, global warming will happen and the world will get hotter. The SHT21 sensor is the kind of sensor that will be utilized in this final project since it has strong and steady chemical resistance over time and uses the I2C interface. This type of sensor is also capable of being utilized as a calibrated ambient temperature sensor, with a digital output form already comprised. This sensor will enable us to create a PID system with feedback that monitors the temperature produced by the Peltier module along with reacting to controlled PID by delivering PWM into the driver, then subsequently transmits the signal to the Peltier module for monitoring. When the duty cycle is 100 percent or the PWM value is set to 255, the Peltier module generates a 12-volt voltage at its best. When duty cycle 0 percent or PWM value 0 is selected, the module stops functioning. It is anticipated that this system will advance toward a Freon-free air conditioning system.

Abstract

Traditional authentication methods, primarily relying on passwords, face several critical challenges. Users often choose weak passwords, reuse them across multiple platforms, or struggle to remember complex combinations, leading to potential security vulnerabilities. As cybersecurity threats continue to evolve, traditional password-based authentication mechanisms have proven increasingly vulnerable to various attacks. Face detection-based login systems have emerged as a promising alternative, offering a balance between security and user convenience. This paper provides a detailed examination of implementing face detection-based login systems, focusing on using Python programming language. The research highlights both the advantages and potential vulnerabilities of such systems while proposing mitigation strategies for enhanced security.

Abstract

Blind people are often hampered in their mobility, while currently available assistive technology includes manual sticks and electronic mobility devices. Currently, the development of smart canes is still being carried out in many studies. Smart cane works by detecting the distance of the cane to obstacles in front of you. From detecting this distance, the response the user gets is generally in the form of vibrations and sounds from the buzzer. The sound provided by the buzzer cannot differentiate the distance between obstacles. Therefore, this study proposes the existence of additional sound playback responses to differentiate far, middle, and near obstacles. Apart from that, the design of the prototype refers to the shape of a flashlight. The smart cane is designed using an Arduini UNO microcontroller with a rechargeable battery power supply with three response components, namely two ISD 1820 modules connected to a speaker to detect long distances (201-300 cm) with a "Hati-hati" sound and medium distances (101-200 cm) with an "Awas" sound, as well as a buzzer and piezoelectric component in the form of a "beep" sound and vibration for close distances (1-100 cm) to obstacles. The result is that both the ultrasonic sensor and response components work according to design. Apart from that, the rechargeable battery supply feature and the implementation of the prototype design make it easier for users to store and use for daily activities.

Abstract

The increasing electricity consumption of the Indonesian population requires renewable energy as an alternative to electricity generation supplies. Renewable energy can be formed through mechanical energy in its simplest form, namely in the form of a footrest. Generally, energy-harvesting floors that utilise human footsteps are designed with piezoelectric sensors. This sensor is responsible for converting mechanical energy into electrical energy. However, the power generated from piezoelectrics is only around 0.041 μW to 240.59 μW. So, in this study, an alternative design for a footstep floor is proposed capable of harvesting electrical energy using a DC generator. The proposed platform consists of a platform design that utilises the translational motion of the gears on the gear rack and is assisted by four springs surrounding the sides of the iron plate. Apart from that, the platform has a power management and storage system. Unlike controllers in general, solar charger controllers are used for charging (voltage and current in the accumulator) and flowing current to the load (lights). The subjects used in this floor test ranged from 20-100 kg. Compared to floors that use piezoelectrics, the results are that floors with DC generators experience an increase in power of around 0.62%. Hence, DC generators are more effective in harvesting electrical energy.
