Menghidupkan dan mematikan lampu penerangan jalan umum, biasanya dilakukan secara manual atau otomatis. Cara manual dilakukan dengan menggunakan saklar sedangkan cara otomatis dilakukan dengan menggunakan sensor cahaya (Light Depending Resistor=LDR) atau dengan Timer (Timeswitch). Dalam penelitian ini telah dirancang sebuah sistem pemantauan dan pengendalian lampu penerangan jalan umum (pju) melalui jaringan internet yang berbasis android. Penggunaan Modul Ethernet dalam hal ini Arduino sebagai system komunikasi data dan smartphone android sebagai pemantau dan pengendali. Aplikasi android akan mengirimkan dan menerima sinyal informasi melalui jaringan internet menggunakan modem ke website sehingga data diterima modul ethernet shield yang kemudian diolah oleh arduino untuk mengendalikan lampu penerangan jalan. Hasil pengujian system menunjukkan bahwa kondisi On menyatakan lampu menyala dan kondisi off menyatakan lampu padam. Rerata akurasi komparasi pengukuran arus sebesar 100% sedangkan rerata akurasi komparasi pengukuran tegangan sebesar 95.23%
<p>The objective of this present article is to describe the record of the ECG 12-lead examination in order to obtain the peaks of the P, Q, R, S and T from each cycle and also to present the Peak of the PQRST and the trajectory path of each cycle of the ECG 12- lead wave. The duration of the peak R to another is used as the period of each cycle, while the Phytagoras theorem is employed to count the trajectory path of the wave in each step. The Peak PQRST is utilized to diagnose the heart condition, and the trajectory path is the distance taken up by the impulses in the heart muscles. The discrete data from the MIT-BIH and the results of the measurement itself are employed as the data to obtain the values of the peak PQRST and the trajectory path of the wave of each cycle.</p>
Penyakit diabetes melitus harus dipantau secara kontinu dan pemeriksaan kadar gula darah secara invasive (melukai kulit), pasien berpenyakit diabetes sangat berbahaya karena dapat menimbulkan luka yang susah sembuh. Peralatan dalam bidang kedokteran untuk pemeriksaan gula darah dalam tubuh telah mengalami berbagai pengembangan, salah satunya pengukuran gula darah dalam tubuh dengan cara non invasive melalui media urine. Namun hal tersebut kurang akurat, maka diperlukan sensor yang dapat mendeteksi perubahan warna kemudian dibaca nilai RGB nya oleh mikrokontroler. Salah satu sensor warna yang digunakan salah satunya TCS3200 dan mikrokontroler Atmega8. Berbagai penelitian pengukuran kadar gula darah dalam urine hanya ditampilkan pada layar LCD dan tidak meyimpan data hasil pengukuran. Dengan permasalahan yang ada, diperlukan suatu alat yang mengeluarkan hasil output pengukuran kadar gula darah dalam urine dan ditampilkan dengan aplikasi database rekam medis pasien sehingga dapat di monitoring secara kontinu.
Proportional, Integral, Dervative (PID) controller is a simple and very reliable controller, but to determine the optimal control system parameters on the PID controller (Kp, Ki, and Kd) is not easy. This paper aims to determine the optimal parameters of the PID controller using Modified Quantum Behave Particle Swarm Optimization (MQPSO) to regulate the speed control of a DC motor. MQPSO is a method that has particle search behavior that is more detailed than its predecessor methods, namely Particle Swarm Optimization (PSO) and Quantum-Behaved Particle Swarm Optimization (QPSO). The test is done through Software In the Loop Simulation (SILS) by representing a DC motor in the transfer function, after the optimal control parameters are obtained then applied to the Hardware In the Loop Simulation (HILS) test using the actual DC motor. The test results show that the PID controller that has been optimized using MQPSO results in achieving DC motor response under steady conditions and is faster than the PID controller that is optimized using Ziegler-Nichols (ZN), PSO and QPSO. The completion time obtained by MQPSO is 41.0201 ms, which is also faster than using QPSO 42.8276 ms, PSO 43.7008 ms and ZN 61.8571ms.
Important parameters that need to b e known from the results of cardiac examination usingElectrocardiograph is the parameter value of PQRST amplitude peak on each lead. Peak P is associated with Atrium depolarization, QRS waves associated with ventricle depolarization and peak T associate d with ventricle repolarization. The PQRST peak values on each lead to date are still manually calculated using small b oxes on the ECG paper. Manual calculations lead to less accurate results and calculated waiting times. Less accuracy can lead to misdiagnosis while waiting times can result in increased disease stage. In this article we have b een ab le to represent the values of PQRST amplitude peak and cardiogram in each cycle on each lead of the electrocardiogram. Continuous signal Electrocardiogram (ECG) examination results, in sampling at certain frequencies to ob tain discrete data which is the amplitude as a function of integer numb ers (N). The maximum amplitude value of each cycle is peak R. The peak time duration R to peak R (dR) is used as the time period of each cycle. A 1.5dR reversal of RN + 1 reverses the starting point of the cycle (sc) while the 0.5dR duration reversal of RN + 1 will b e ob tained b y the end point of the cycle (ec). The maximum and minimum amplitude values b etween sc and peak R are peak P and peak Q respectively, while the minimum and maximum values b etween peak R to ec are peak Q and peak T respectively. Discrete data from Physionet MIT-BIH and b meuwg are used as data to ob tain PQRST peak electrocardiogram parameter values in each cycle.
In the boarding house the use of water for each person is different for each occupant of theboarding house. The increase in water use is not proportional to the increase in water capacity and theequalization of payments for each boarding house is different. Utilization of technology Internet ofThings (IoT) and the freechat application Telegram in the application to monitor water usageinformation for each boarding house occupant. In this study, a water monitoring device was made tomonitor information from two different platforms. The server can monitor water usage information forall residents of the boarding house. Telegram provides notification information when the water capacityof boarding houses is approaching empty from each device. Using Arduino and ESP8266 as controllersand wifi connection with the server. With this system, it is easier for the boarding house owner tomonitor the water usage of each boarding house occupant.
