MICROCONTROLLER APPLICATIONS BASED FUZZY LOGIC CONTROLLER FOR TEMPERATURE ON BREEDING FISH POND carp Dian Efytra Yuliana
Journal of Telematics and Informatics Vol 5, No 2: September 2017
Publisher : Universitas Islam Sultan Agung

Carp is a freshwater fish that have economic opportunities to be cultivated. In the maintenance required carp control well to temperatures that are too low can affect the ability of the organism to bind oxygen so stunted. To overcome this, do a system that can keep the working temperature automatically. This tool works on the basis of the readings of the temperature sensor into the ATmega16 microcontroller through ADC port. ADC readings used fuzzy logic control input on the program. Results defuzzification program is used to set the amount received by the circuit pwm solid state relay. Pwm magnitude proportional to the voltage received by the heater, so that the heat of the heater can be set large. The water in the aquarium box (prototype pool) will be in circulation by the pump. This device has a high degree of accuracy in monitoring the temperature inside the pool, while the difference in temperature with the thermometer sensor has an average percentage error with high accuracy level. Keywords : Fuzzy logic, heater, pompa, AT Mega 16, Solid State Relay

Implementation Speech Recognition for Robot Control Using MFCC and ANFIS Trima Mustofa

Speech recognition is one of machine intelligence field that grow rapidly, it is recognized by almost all technology devices that equipped by voice command. The process of converting voice patterns into text through complex transcription process. There is an enormous complexity involved in analyzing speech input, such as variations in pronunciation, accent, speaker physiology, emphasis and acoustic environmental characteristics in generating hundreds of different phoneme classifications for each sound. A sound pattern recognition system is required to process sound signals quickly and realtime in recognizing voice input with accurate results. In this case MFCC is an appropriate method to apply sound extraction because it presents the signal well. While ANFIS is needed for sound characteristic learning because it has advantages possessed by fuzzy inference system and artificial neural network system. In this research tested through robot control. Keywords: ANFIS, MFCC, Speech Recognition, Robot Control

Hodotermitidae Optimization Algorithm for Reduction of Real Power Loss Lenin Kanagasabai
Journal of Telematics and Informatics Vol 5, No 2: September 2017
Publisher : Universitas Islam Sultan Agung

In this paper, a unique technique, called Hodotermitidae Optimization (HO) algorithm, is utilized for solving reactive power problem. Hodotermitidae Optimization (HO) algorithm is an population based optimization method which is inspired from rational behaviours of Hodotermitidae. The projected Hodotermitidae Optimization (HO) algorithm provides an option making model which is used by Hodotermitidae to adjust their progress trajectories. Hodotermitidae move arbitrarily in the search space, but their trajectories are inclined towards regions with more pheromones. The proposed Hodotermitidae Optimization (HO) algorithm has been tested in standard IEEE 57,118 bus systems and simulation results demonstrate the commendable performance of the projected Hodotermitidae Optimization (HO) algorithm in reducing the real power loss.

So many publications are increasing every year and it causes an overflow of data and it makes the information function on the site cannot be delivered entirely to the visitors. As a scientific publication site, the IPI garuda portal (Index of Indonesian publications) has more than 4000 Indonesian journals in the database. Therefore it will be designed a system that can provide information and knowledge for the user. The system can also provide recommendations related articles and relevant for users. Recommendations are made by calculating similarities between related documents. The similarity calculation method used in this research was cosine similarity. The steps taken were pre-processed, weight calculation, vector length and then they were calculated using cosine similarity so that the value would be achieved that ranged from 0 to 1. Performance testing of recommendation system used precision and recall. Performance system with average precision value about 0.664 meant that the document had good system accuracy, and then the average recall point with value about 0.962 meant that documents were successfully returned by the system.

In water treatment process, highly temperature and humidity can lead to rapid evaporation, thus increasing uses of coagulants. It influence degree of acidity or pH. Therefore, it is necessary to monitor its conditions gradually. This work proposes a real-time monitoring of temperature, humidity and pH in the water treatment plant using internet of things. The system prototype was implemented using DHT22 and pH sensors to measure the physical conditions, Arduino UNO to process the data, ESP8266 to send the data into Internet Cloud Server over MQTT protocol. The prototype was measured in the plant comparing with the conventional instruments. The results show that error of temperature is 1.92%, humidity is 9.55%, and pH is 0.97% comparing with the conventional instruments. It is possible applying the prototype in the plant, but needs improving accuracy of humidity sensors.Keywords: Humidity, internet of things, pH, temperature, water treatment.
