Abstract

The room temperature depends on the intensity of light. Low light intensity is not proper for the room because it causes bacteria or fungus on the room’s walls. We create a telemonitoring system and air quality control in semi-indoor rooms using wireless sensors as a support system. It can provide real-time information to the user on the screen display. In this study, we use a wireless sensor as monitoring, VEML6070, DHT11, and BH1750 as sensors to determine the air quality in the semi-indoor room. Data will be sent from Arduino Uno to a server through raspberry pi 3 and NRF24L01. Client-server communication techniques are designed for communication between the node and the server, so the data transmission errors can be pressed. The display of the work system will be monitored using a display in the android application. From the experimental results, the system between the node and the server runs well. The experimental results obtained varying Delay with an average delay of 0.318 seconds when there is no change in conditions on the fan and UV lamp. The average Delay is 0.491 seconds when there is a change in conditions on the fan and UV light

Abstract

A humanoid robot is a robot that has a human-like shape, which has a body and head, two arms and two legs that allow it to move and interact with the environment created by humans [1]. The humanoid soccer robot system currently used still uses the Robot Operating System (ROS) system, which is basically in the system without any encryption or data security every time communication is made by sending and requesting or what is commonly called Publish and Subscribe. In order to develop the humanoid soccer robot, this research is designed for "Implementation of Advanced Encryption Standard (AES-128) Cipher Block Chaining (CBC) Mode as Communication Security for Humanoid Robot Movement KRSBI". Which is designed to operate in low quality connectivity, with network bandwidth that secures every node running on the ROS which includes features for subscribing to topics and also publishing topics. Then with the addition of cryptography can keep data or messages safe when sent, from sender to receiver without experiencing interference from third parties. According to Bruce Scheiner in his book "Applied Cryptography", cryptography is the science and art of keeping messages secure. [2] So all communications are encrypted using Secure Sockets Layer (SSL), or more specifically Transport Layer Security (TLS).

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.
