<![CDATA[Electrocardiograph (ECG) is a recorder of human heart signals with signal output on a monitor or graph paper. The ECG records the measurement of the electrical activity of the heart from the surface of the body by a set of electrodes that are installed in such a way that reflects the tapping point activity. The pattern of ECG output signals in one heartbeat produces a pattern with a peak point P, Q, R, S and T or QRS complex. ECG signal waveform results were analyzed using Learning Vector Quantization (LVQ) Artificial Neural Networks, and grouped into two classes, namely normal and abnormal heart patterns. The normal heart condition that is trained is a medically normal heart categorized as healthy as 10 data, while an abnormal heart (Heart, Coronary Heart, and Aortic Regurgutation) is 20 data. The LVQ method recognizes the input pattern based on the proximity of the two vectors, namely the vector of the input unit or neuron with the weight vector produced by each class. Online LVQ identification (using ECG) recorded from 25 direct trials resulted in 80% accuracy.]]>

<![CDATA[Shopping Mall merupakan area pusat perbelanjaan yang besar dan memiliki sistem keamanan seperti sistem layanan informasi yang dapat dimanfaatkan oleh konsumen untuk mendapatkan informasi yang dibutuhkan. Penggunaan sistem layanan informasi pada area Shopping Mall bagi konsumen terkadang sangat tidak efektif. Hal ini dikarenakan konsumen membutuhkan waktu yang lama dalam mendapatkan informasi, dimana konsumen terlebih dahulu harus mencari lokasi tempat sistem layanan informasi tersebut. Hal ini menjadikan sistem keamanan pada Shopping Mall menjadi lemah. Indoor Positioning System (IPS) merupakan sistem yang dapat digunakan untuk mengetahui posisi pengguna melalui kekuatan sinyal Wi-Fi yang didapat dalam gedung. Pada penelitian ini, penulis membuat suatu aplikasi android yang dapat digunakan untuk mengetahui posisi konsumen pada area Shopping Mall tersebut.]]>

<![CDATA[Diabetes mellitus and gastric infections can be detected through bad breath bad breath (halitosis). Halitosis is a condition where the smell of bad breath occurs when a person exhales (usually smells when talking). This study aims to create an oral health identification and classification system (halitosis). TGS-2602 gas sensor will detect gas levels in the mouth of the patient, and send data in the form of an analog signal to the ATmega 328 microcontroller. By programming the data read on the Raspberry Pi, the data from the microcontroller is stored in a file and then the data is processed using the Fast Fourier Transform method. (FFT) so that the desired data pattern is obtained. The data pattern of the Fast Fourier Transform (FFT) output will be used as input data on the Learning Vector Quantization (LVQ) neural network method. System testing is done to people with halitosis and not halitosis bad breath. The results showed that the percentage success rate of sensor responses to mild halitosis samples was 25%, moderate halitosis samples were 50%, acute Halitosis samples were 50% and non-halitosis samples were 100%.]]>

<![CDATA[In this study, the total dissolved solid (TDS) in water was made using conductivity sensor which the sensor works by using the principle of conductance that is the ability of the solution in delivering the electric current, so the more content of solute contained in the water the greater also the value of its conductance. The measurement results of the sensor will be compared with the next setpoint value will be used to turn on the booster pump which will do the filtering process in order to decrease the TDS water content by using RO membrane. The performance of sensor readings when first used is boosted by the time at which the system takes 3 minutes to reach a stable state, while for the whole system is influenced by the volume of water that will decrease its TDS level. The test results are presented in the form of graph of change of TDS water content over time, the difference of time required to decrease the TDS level by 15 ppm for 1 liter of water for 6 minutes, 2 liter of water for 10 minutes and for 3 liters of water for 16 minutes.]]>

<![CDATA[The development of computer technology in Indonesia is currently growing rapidly. In line with this the development of the Potato Seed Center (BBI) of potatoes was also developing, as was the case at the Kerinci Regency mother's seed plant. Processing of potato hatchery and hatchery development reports has not been computerized because it still uses Microsoft Excel, causing some problems including making reports on the development of potato hatcheries and searching for data takes quite a long time. This led to a weak processing of hatchery data processing systems and the development of reports on the development of Kerinci Regency potato seeding. Seeing the above problems, a potato seeding information system at the Central Seed Agency (BBI) was made using a C # programming language that had used a database and used Crytal Report to assist in the development of a report on the development of potato seedlings in the potato seed plant in Kerinci district.]]>
