Abstract

Water has an important role in maintaining life. Without water, humans cannot carry out their daily activities, because water is an inseparable part of their daily activities. Water that is good for humans is water that has met the requirements as suitable water for daily use. For this reason, there have been many studies on water classification in determining water quality. However, in determining the results obtained, the accuracy is less than satisfactory and can be improved again. In determining the classification of water, the K-Nearest Neighbor (FK-NN) fuzzy method is used. Some of the attributes or parameters that will be used in this research are the degree of acidity (pH), TDS, NO2, NO3, hardness, chloride, manganese. There are several tests carried out including testing the k value, the distribution of data ratios, and the distribution of data classes. From this test, the accuracy value is 95.52%, with the data ratio level consisting of 70% training data and 30% test data, with a K value of 10.At the level of data class distribution, 80% accuracy is obtained with the distribution of test data classes using 20 data with class 0 is 10 and class 1 is 10. From the accuracy obtained, it is concluded that the accuracy value obtained is much greater than the accuracy of previous research which is only around 78.70% and 85.70% in the Support Vector Machine and Naive Bayes methods..

Abstract

Indonesia is a country that is rich in natural resources, there are many pine trees that produce sap. Pine tree sap has many uses in the cosmetic, antiseptic and pharmaceutical industries. But pine sap produces a waste effect. There are still many things that need to be improved on the processing of gondorukem for wastewater treatment. Especially in the disposal section, it is not possible to predict a good standard of liquid waste disposal. The standard for wastewater disposal has several parameters such as pH, temperature and turbidity of the waste. With IoT technology, it makes it easier for us to reduce the pH, temperature and turbidity of the waste by using a pH meter water sensor, DS18B20 and Turbidity. The data of the three sensors are collected to the sensor node, then sent to the gateway via a websocket, then forwarded to firebase which will be displayed on the web interface. Testing uses Quality of Service, to determine a network speed performance when sending, which is useful for knowing the time of each delivery and packets lost during delivery. The water meter's pH sensor function, DS18B20 and Turbidity, worked well during research. Then obtained from the test results based on the throughput h-1 to h-4 testing is 17.01 bps, 20.89 bps, 19.83 bps and 18.86 bps. For packet loss h-1 to h-4, namely 0.1%, 0%, 0% and 0.%. Then the delay h-1 to h-4 is 0.08 s, 0.07 s, 0.07 s, and 0.07 s.

Abstract

The nRF24L01 module is more frequently used to send data on Wireless Sensor Network (WSN) compared to the ESP8266 module. This is because of the nRF24L01 module tend to be an Ultra Low Power (ULP) module which requires less power and can transmit data at speeds of 2Mbps. The nRF24L01 module can use 125 different channels and able to create 125 networks in one area and on each channel that has up to 6 addresses. The number of channels and adressess which can be made by the nRF24L01 will make the data traffic will be slightly harder to control and will having a chance to cause a security problem, such as it becomes more vulnerable to hack. Because there is an opportunity for the problem to occur, cryptographic method is needed to encrypt communications on the nRF24L01 module. The Light Encryption Device (LED) algorithm is a development of the Advanced Encryption Standard (AES) algorithm and it is compatible with hardware because this algorithm is a fairly light algorithm if compared to other symmetric block ciphers in its class such as the AES algorithm itself, so that this LED algorithm can implemented in WSN with nRF24L01 module which tend to be Ultra Low Power to fulfill the basic principle of confidentiality security. The implementation of the LED algorithm on the system makes this system resistant to even passive and active attacks. Keywords: Wireless Sensor Network (WSN), nRF24L01, Light Encryption Device (LED)
