 Swarm Intelligence is an artificial intelligence developed by adapting the social beliefs of a group of animal. In the migratory birds community, information technology is known that the behavior of the birds during the flight forms a 'Five' germination that plays a role in optimizing the bird'southward energy saving. The bones principle of a swarm intelligence is the being of collective, decentralized and self-organizing behavior. This is the basis for the evolution of behavioral algorithms flocking birds called Particle Swarm Optimization (PSO).In this research used three mobile robot equally object to implement PSO algorithm. 3 pieces of this robot is homogeneous, which is similar hardware and software. A group of these robots volition complete the joint mission of defining the robot with the closest distance to the target TPr (robot handler). There are three TPr targets that accept to be executed by the robot handler co-ordinate to their position with the target point to be completed. The test is done by taking odometry data every 250 milisekon and data frame robot communication.At the end of this enquiry, the result of modeling system result of PSO algorithm implementation on mobile robot group to decide the robot closest to the target. The robot system that meets the principles of PSO, namely the process of data sharing and learning process.

During this time to clasify quality of cacao based on color and odour involving human taster. But this cacao tester still has weaknesses such every bit subjective. Besides that, the standard chemical analytical methods requires a high cost and demand expertise to analyzing it. Basically aroma of cacao is determined by volatile compounds such aldehid and alcohol. Electronic nose based on unselected gas sensor array has the ability to clarify samples with complex compositions that tin can be known characteristics and qualitative analysis of the samples. Stimulus smell is transformed by electronic olfactory organ into fingerprint information then it is used by characteristic extraction procedure using the differential method. The results of feature extraction is used to process the neuro fuzzy grooming to obtain optimal parameters. The parameters have been optimized is then tested on cacao. Based on test results, neuro fuzzy can clasify samples with 95,21% accuracy rate so that the clasification of cacao quality with electronic nose using neuro fuzzy has been successfully carried out.

This inquiry aims to classification of samples of green tea and black tea originated from different planting sites,  Tambi and Pagilaran. Samples of green tea and black tea; quality I (BOP), quality 2 (BP), quality Iii (Bohea) were each collected from Tambi and Pagilaran to clarify the charasteristic of both sample from both sites. Measurements of tea samples were performed using a dynamic due east-nose device based on a MOS gas sensor, with a maximum fix indicate temperature of 40ºC, flushing 300 seconds, collecting 120 seconds, and purging 80 seconds for 10 cycles repeatedly. The resulting sensor response is and then processed using the difference method for baseline manipulation. Characteristic of extraction procedure on the sensor response results is carried out in three methods; relative, partial change, and integral. Matrix data of the feature extraction results was reduced using the PCA method by mapping the aroma patterns of each sample using 2-PCA components. The PCA reduction results in integral feature extraction showed the largest percentage of cumulative variance in classifying greenish tea sample data past 97% and black tea past 100%. The large per centum value of cumulative variance indicates PCA can differentiate samples of green tea and black tea from Tambi and Pagilaran well.

Modulus of elasticity of physical unremarkably measured by Destructive Testing which is not considered as an effective way, because It will destroy the concrete. Ultrasonic Pulse Velocity tin be a solution to measure value of modulus of elasticity without destructing it. The concept of the system is to look for velocity of wave, then put the value into modulus elasticity formula.UPV system will transmit ultrasonic wave through physical. HC-SR04 used for generating 40 kHz wave, increasing voltage of wave on receiver, and calculating time travel. The voltage of wave sent by HC-SR04 is only about x volt, then that power and voltage of wave has to exist amplified. Piezoelectric is used as a transducer which tin converts electrical to mechanical free energy.  The results of this inquiry shows that fault value on wave velocity measurement have an boilerplate value for well-nigh eighteen,2% compared to event of UPV Pundit. Static modulus of elasticity from compressive examination is compared to value of dynamic modulus of elasticity that is obtained by UPV organisation with HC-SR04. Ratio between ii values is almost 45% - 249%.

Diabetic retinopathy is a vision disorder disease that tin can cause impairment to the retina of the eye that will have a directly impact on the disruption of vision of the patient. The diabetic retinopathy phase is classified into four types (normal, mild NPDR, moderate NPDR (Not-Proliferative Diabetic Retinopathy), and astringent NPDR). Retinal of heart data of diabetic retinopathy patients treated from the MESSIDOR database. Past applying image processing, the retinal image of the eye in extraction using the area features extraction from the detection of exudate, blood vessels, microaneurysms, and texture characteristic extraction Gray Level Co-occurrence Matrix. The extracted results classified using the Support Vector Machine method with the Radial Basis Function (RBF) kernel. Classification evaluated with these parameters: Accuracy, specificity, and sensitivity.The results of classification show the best value using 6 statistical features ie, contrast, homogeneity, correlation, free energy, entropy and inverse divergence moment in the direction of 45 degrees with the RBF kernel. The outcome of classification research system on 240 information training and 60 data testing yields an average accuracy is 95.93%, the value of specificity is 97.29%, and a sensitivity rating is  91.07%. From the enquiry consequence, using RBF kernel get the all-time accuracy result than using kernel polynomial or kernel linear.

 Measurement of water discharge using ultrasonic wave properties ensures the stability of measured h2o profile because of its non-intrusive nature. In this study, a water discharge measuring device has been developed by utilizing ultrasonic wave properties to determine its speed. The device is designed using two pairs of ultrasonic transmitters and receivers at upstream and downstream positions toward the direction of the h2o flow. forty kHz ultrasonic waves are generated with AD9850 DDS sinusoidal pulse generating module. The sensor data processor uses an Arduino Due microcontroller module by calculating the measured ultrasonic wave travel time deviation.             Measurements were made on a 57 mm bore pipe with menstruum rates varied using 25%, 50%, 75%, and 100% tap openings. The measurement resulte shows the lowest water debit calculation value of 4.42×10-4 m3/southward at 25% faucet opening and highest discharge of 2.15×10-3 m3/s at 100% faucet opening with the values of coefficient of correlation and coefficient of determination on 25%, fifty%, 75% and 100% faucet openings respectively 0.9715, 0.9669, 0.9604 and 0.9647 and 94.37%, 93.49%, 92 , 24%, and 93.07%.

Cognitive process show how brain piece of work from stimulus reception until stimuls reaction. With electroencephalogram (EEG) device, cognate process tin can be observerd in brain signal or EEG signal form. In cognitive process unlike kind of stimulus could touch on generated brain signal. Besides, given interference in cognitive prcess could bear on brain signal. In this enquiry, conducted ascertainment whether gender difference has effect in cognitive process. Numerical stroop task with three kinds of conditions (congruence, incongruence, and neutral) are used as reference in signal observation process which is generated when the cognitive procedure in difference genders are done. The resulting EEG indicate then conducted 3 kinds of analysis that is ERP analysis, reaction time, and energy analysis. The upshot of ERP analysis show both subject class have difference in response time that indicated with P3 peak time. On average, respons time in female (kongruent = 623,34 ms; inkongruent = 645,18 ms ; neutral = 614,91 ms)subject class is faster than male (kongruent = 709,67 ms; inkongruent = 745,00 ms; neutral =715,37 ms) bailiwick form. Energy analysis show when numerical stroop job takes identify, left side of the encephalon (51,36%) and cetral side of the brain (50,65%) more than ascendant than others parts of the brain.
