Abstract

The random noise signal is widely used as a test signal to identify a physical or biological system. In particular, the Gaussian distributed white noise signal (Gaussian White Noise) is popularly used to simulate environmental noise in telecommunications system testing, input noise in testing ADC (Analog to Digital Converter) devices, and testing other digital systems. Random noise signal generation can be done using resistors or diodes. The weakness of the noise generator system using physical components is the statistical distribution. An alternative solution is to use a Pseudo-Random System that can be adjusted for distribution and other statistical parameters. In this study, the implementation of the Gaussian distributed pseudo noise generation algorithm based on the Enhanced Box-Muller method is described. Prototype of noise generation system using a minimum system board based on Cortex Microcontroller or MCU-STM32F4. The test results found that the Enhanced Box-Muller (E Box-Muller) method can be applied to the MCU-STM32F4 efficiently, producing signal noise with Gaussian distribution. The resulting noise signal has an amplitude of ±1Volt, is Gaussian distributed, and has a relatively broad frequency spectrum. The noise signal can be used as a jamming device in a particular frequency band using an Analog modulator.

Abstract

Physical exercise is an activity carried out to maintain a healthy body condition. Health is the most important part of all activities carried out by humans by paying attention to vital signs such as body temperature, heart rate, and others on a regular basis. Regular physical exercise for a long time, which is about 30 minutes, can cause changes in bodily functions. The acute effect of excessive physical exercise results in an increase in heart rate and body temperature. This study is designed to control and monitor body temperature as well as other vital signs of health during exercise, and to avoid excessive physical exercise. Research that has been conducted previously obtained the results of values before exercise for body temperature using infrared and ds18b20 which have a range between 34.550C - 36.090C and 35.060C - 36.190C, values for skin moisture range from 47% and heart rates between 94 Bpm - 118 Bpm. Meanwhile, during the exercise, the body temperature is between 36.380C - 36.810C, skin moisture between 47% - 15%, and a heart rate between 105 Bpm - 95 Bpm with a value of delay between 0.034897000s - 0.037563000 s during the live streaming. Based on this research, it can be concluded that the fan can turn on automatically and successfully reduce the user's body temperature gradually with a temperature range between 35,000C - 36.80C.

Abstract

According to the World Health Organization (WHO), an elderly person is someone who has entered the age of 60 years and over. Based on recorded data from Radio Suara Surabaya from January 2017 to July 2019, Radio Suara Surabaya has received 618 listener reports of missing people due to dementia or senility. This research aims to provide an alternative in order to keep an eye on the presence of the elderly by utilizing the U-Blox Neo 6m GPS module and the ESP8266 NodeMCU microcontroller. In addition, supervisors can use an android application to implement geofence technology. The results of the research conducted gave the results by testing the GPS U-Blox Neo 6m module placed in different locations and conditions resulting in receiving information signals obtained from 3-9 information satellites that send signals. The distance difference test was carried out at 10 different location points resulting in a difference in the distance from 1 m to 8 m. In addition, there is data transmission delay testing carried out at different times of the morning, afternoon, and night which results in delays ranging from 0.2 seconds to 1 second. Based on the research conducted, it can be concluded that the implementation of geofence results in a geofence application that can apply geofence to the elderly by depicting a circle radius of 100 m based on the center point of a specified location. The use of GPS U-Blox Neo 6m gives results by calculating the average distance difference of 3.7m.

Abstract

The use of digital filters is needed by electronic systems, such as in signal and audio processing. The use of digital filters is to filter frequencies and modify the frequency spectrum of a signal so that the desired goal is obtained. The purpose of the filter is a series that passes a certain desired frequency band and dampens other frequency bands. The method used in designing the FIR filter is using the windowing method. There are several techniques included in the windowing method, namely rectangular, hamming, hanning, and kaiser. For the windowing work system it really depends on the type of window used, therefore there is a comparison between the four. This research will be developed by designing a digital FIR filter that is implemented on the raspberry pi device which is expected to be well integrated using the simulink matlab. So a study was made that raised the problem of how to process digital signals to apply the FIR filter using the windowing method that was simulated using the matlab program and implemented on raspberry pi. From the test results, it can be seen that the Raspberry pi can be integrated well using the Simulink matlab. The bigger the ripple, the stopband attenuation, and the bandwidth width on the result of the signal output frequency response affect the resulting order, that is, the smaller it is.

Abstract

Tofu has the best quality vegetable protein because it has the most complete amino acid composition and is believed to have high digestibility (85% -98%). According to SNI 01-3142-1998 and SII No. 0270-1990 testing criteria for soy tofu based on smell, taste, color, appearance, or texture. Tofu soybeans are prone to physical or texture damage due to factors such as inappropriate pH levels and insufficient storage which results in damaged tofu. Therefore in this study, it is proposed to determine the elasticity of soy tofu with the parameters tested are the pH level in the manufacture of soy tofu, the storage temperature, and the capacitance value to see how thick the tofu is with a capacitive sensor using the capacitor principle. Where the parallel plate capacitor is a capacitor consisting of two parallel metal plates. The test results of all sensors are sent to the database and will be displayed on the page on the Android application which will provide real-time sensor output information to the user. Based on the results of testing on this system using a pH sensor, the pH value is around 3-4 which indicates that the pH level used is very good for use in tofu processing, at pH 4.56 with storage at 29 ° C the highest elastic capacitance value is 3.58. In testing data delivery, the throughput value is 4336,217 b / s and the smallest delay value is 0.017ms because the smaller the delay value, the better the quality of data transmission because there will be no delay in sending data.

Abstract

Toluene is one type of organic solvent that is widely used in industry. Organic solvents can have a negative impact on health when exposed to the human body through inhalation (breathing), digestion (swallowing) and adsorption (skin contact). This compound is widely used as a basic material for solvents, dyes, paints, resins, perfumes, nail polish, gasoline, glue, solvent thinner, immersion ink, and printing. The impact on each human will vary depending on the concentration, duration and toxicity of the solvent. The effects of exposure are generally long-term and short-term. Short-term effects include respiratory complaints and eye irritation in exposed humans. An ESP32 microcontroller, HCHO sensor, and DHT11 sensor were used in this study to construct a system to lessen the effects of toluene exposure on workshop personnel. Temperature and humidity sensors picked up by DHT11 have an average value for each node. Each node's average value for the temperature and humidity sensors detected by DHT11 is available. The average error value is categorized as accurate and good for nodes A and B, which are separated by 2 meters and 4 meters, respectively. Due to the DHT11's error rates, the temperature range is 20C and the humidity range is 5% RH.
