Abstract

The choice of transmission devices in the technology of the Wireless Sensor Network (WSN) is very important. At present one of the problems that is still being examined in WSN technology research is the speed of data transmission. Because the energy requirements used by the system are getting smaller, it will result in more data transmission. To overcome this problem, a low-power RF XBee S2C device is chosen but data transmission performance is better. By analyzing the throughput value and Range-test analysis to find RSSI values ​​and the percentage of data sent, XBee S2C was tested with a variety of test distance traveled scenarios, namely 10 meters to 400 meters, and variations in the number of load-throughput testing packages, namely 1 byte to 255 bytes, and the number of packages in the range-test is 1 byte to 84 bytes. Loss packages are detected at a distance of 400 meters. The results of the analysis of throughput, distance and size of the package do not really affect the performance of XBee S2C data transmission. Pearson test results on throughput produce the highest value of 0.961231 (delivery with a distance of 10 meters), and the lowest yield is -0.96648 (delivery with a distance of 150 meters Pearson field test results on maximum Range-test were valued at 0.863349 at 300 meters test and a minimum value of -0.87328 at a distance of 300 meters. The range of the test range greatly affects the RSSI produced. However, the data sent remains stable from a distance of 10 meters to 300 meters with an average of 80-90% of data successfully sent, and new connections will be lost at a distance of 400 meters.

Abstract

Blind is a condition where the both senses of sight do not work to receive information like the alert person, that's why it needs auxiliary tool like stick to carry out daily activities. However, the stick still has a deficiency too that can only be used to touch objects or obstacles with a limited range. One of technologies that enables blind people in carrying out daily activities is to use computer vision for processing of digital image that can detect a barrier object when a blind person walks in the room. This system uses a webcam camera as a censor attached in front of the user's chest at a height of 110cm and a camera tilt of 41áµ’, so that it can take the image in front of the user up to 125cm. The detection process of this barrier object is done in several steps, such as resizing the image, cropping, then thresholding. This thresholding process utilizes values from the RGB image of floor. To get a blob in the image uses connected component labeling 4 connectify used to label pixels. Pixels that have been labeled will be analyzed to be able to detect barrier object. From the study that has been done by the system, it can detect barrier object with accuracy of 91,66%. The result of study for accuracy of system integration with hardware is 98.33%, and the average time of system computing is 166.15 ms.

Abstract

Culverts are a water channel that is very beneficial for the environment in the community. With the culvert the public must be responsible to maintain well in order to avoid things that are not desirable like flooding due to clogged or overflowed. Clogged water channels because the people who often dispose of waste into culverts or other water channels so that plastic waste or organic waste clog water channels due to too much waste. Therefore, a blockage monitoring system was built on three aqueducts with each node using an ultrasonic PING sensor to measure the water level and the water flow G1 / 2 sensor to measure the rate of water velocity on the culvert. Data taken from the sensor will be processed by Arduino Nano microcontroller by using fuzzy method. Because the location of the culvert with a monitoring post is relatively far then the data processing will be sent using wireless NRF24L01, then LED RGB (Light Emitting Diode Red, Green, Blue) as output will produce conditions on the culvert with a red flame is stated danger, green declared alert and blue otherwise safe. in this study fuzzy method has been successfully applied on a system with 100% accuracy with average processing time of delivery is 1236, 1045 and 1133 millisecond.

Abstract

The human lung is an organ that is susceptible to disease because it is in direct contact with the air inhaled through the nose. Lung medicine is currently using CT scan and sputum tests which are checked manually by sputum experts. Many people still do not know about this treatment system, and finally they are reluctant to check their lung health, because they feel inefficient and besides that the results of the tests can't go out immediately. based on these problems, there is a need for research related to the automation system to detect the severity of lung disease from patients, so when a patient comes to check their lungs, the results can be immediately known. In this study the parameters used to compare the grade level of lung disease are nail color and body temperature of patients using the Naive Bayes method. It is known that the Naive Bayes method has good accuracy and can be used based on class classification at the beginning of the process. Based on several tests carried out on the system generated TCS3200 color sensor reading error of 1.478%, and the LM35 temperature sensor reading error against the thermometer measuring instrument is 1.13%. Furthermore, testing the system using the Naive Bayes method with the number of training data as many as 24 data and test data as much as 12 data, obtained an accuracy of 91.6% with an average computing time of 0.69 seconds.

Abstract

HTTP is a network protocol on the TCP / IP application layer that is used for communication or data exchange between the server and the client. There is a weakness in the HTTP protocol where the data or information transfer does not have a security or encryption process which can endanger the information or data sent on a network. There is already a development to overcome security issues on the HTTP protocol, namely by using the HTTPS protocol. However, the HTTPS protocol consumes a lot of memory and drains a lot of resources in processing so it is not recommended to be implemented in embedded systems. This study proposes to use one of the existing cryptographic algorithms implemented on the HTTPS protocol, which is the AES algorithm which plays a role in data encryption in the HTTPS protocol which fulfills the confidentiality. In this study using Arduino Uno as a microcontroller used to process DHT11 and NI Labview sensor data to display the output of the system. HTTP server and encryption process are implemented in Arduino IDE and HTTP client and decryption process at NI Labview. From the test results obtained the average value of encryption and decryption processing time is 13.048 milliseconds with the average delivery delay on the HTTP protocol by 0.091073 seconds. From the test results concluded that the AES algorithm can be implemented to secure the data transfer from the DHT11 sensor using the HTTP protocol.
