Abstract

Early warning system of door security based on IoT with piezoelectric sensor, this was an early warning system wich could detect a threat on the door and send a notification to the owner smart phone to do preverentive action. This system was made with affordable cost, wich anyone can own this not only the rich one. This system will classified wich a safe knkck and a threat. This system used piezoelectric sensor to monitor a threat and buzzer to make some noise around. This system was equiped a relay to control the solenoid lock as your primary lock. This system used blynk cloud as the based wich could be operated on smart phone. The test used one room and one door. Take a survey to decide wich a normal knock and a stroke. And as got the result, then set the set point based on the output voltage of the sensor, as a threat to the door. Wich that the microcontroller could send a notification to the blynk apps on smart phone. After tahat we did some test to the respond time of, notification, buzzer, and the relay. Wich the respond time of notification was 2,15 second, the buzzer was 1,1 second, and the relay was 1,15 second. This system has 80% accuracy. This system might be well monitored the door with blynk apps.

Abstract

Abstrak - Implementasi Energi Baru dan Terbarukan (EBT) tenaga surya di Indonesia sudah banyak berkembang. Dari penentuan tarif hingga stabilitas jaringan distribusi, masih banyak kekurangan – kekurangan dari sistim distribusi dengan menggunakan panel surya atau modul PV bila digunakan dalam skema penghasil tenaga listrik atau berperan sebagai Independent Power Producer (IPP)-Residensial. Salah satu kekurangan proses pembangkitan tenaga surya konvensional adalah tidak adanya fungsi kompensasi daya reaktif (Q) karena modul panel surya umumnya digunakan untuk memenuhi keperluan daya aktif (P) baik itu pada jaringan ataupun pada modul beban yang terhubung pada grid utama. Hal ini mengakibatkan rendahnya faktor daya pada beban sehingga sistem harus mengambil kebutuhan daya reaktif dari grid sehingga biaya operasional akan bertambah besar dan mengurangi faktor daya dari jaringan utama. Pada penelitian ini diharapkan dapat memberikan ilustrasi terhadap implementasi sistem PV-Inverter menggunakan kendali Artificial Neural Network (ANN). Injeksi daya aktif dan reaktif pada grid akan diregulasi melalui inverter yang dikendalikan mengunakan ANN dengan referensi daya dari Photovoltaic.

Abstract

In the electricity generation business in Indonesia, power plants requiring to be reliable when operating and ready when needed due to network load requirements. It has been written in the performance target contract for each unit, therefore the protection system installed at the power plant must be well. The problem that occurs at the PLTGU PT PJB Gresik Generation Unit is a malfunction in the HV Line protection system that causes the generator unit to trip, thus causing questions regarding the cause of the problem that occurs. Therefore, the authors compile a thesis proposal with the title "Identification of HV Line Protection Interference at PLTGU PT PJB Gresik Generation Unit Using RCFA and FDT Methods" which can find out the source of the problem that occurs so that it does not occur repeatedly. The benefit that can take is knowing the problem cause of the HV Line protection system malfunction so that it can be done correctly and on target for future unit reliability.

Abstract

Serial Peripheral Interface (SPI) is a synchronous serial communication whose data or signal transmission involves Chip Select (CS) or Slave Select (SS) pins, Serial Clock (SCK), Master Out Slave In (MOSI), and Master In Slave Out (MISO). In the Arduino Uno, there are four pins that allow Arduino Uno to perform SPI communication. In this research, SPI communication is implemented to expand the output of the Arduino Uno by using the features of the MCP23S17 IC so that the Arduino Uno, which initially has 20 output pins, can expand to 36 output pins.The results of the research show that the Arduino Uno manages to control 36 output pins. 16 output pins from the MCP23S17, 16 output pins from the Arduino Uno, and 4 pins are used for the SPI communication line. The results of this study also show the form of the SPI communication signal from Arduino Uno in declaring 21 registers on MCP23S17, declaring the MCP23S17 pin register as output, and implementing the output using LEDs.

Abstract

Technology in the modern day has led to the development of agricultural robots that helps to increase the agriculture productivity. Numerous research has been conducted to help increasing the capability of the robot in assisting agricultural operation, which leads to development of autonomous robot. The development aim is to help reducing agriculture’s dependency on operators, workers, also reducing the inaccuracy caused by human errors. There are two important development components for autonomous harvesting. The first component is Machine vision for detecting the crops and guiding the robot through the field and the second component actuator to grab or picking the crops or fruits.

Abstract

This article addresses the study of the Vivaldi Antipodal Antenna (AVA) seeking to improve the gain, decrease the Side Lobe Level (SLL) and the squint, to make the antenna more directive and obtain a more stable radiation pattern. Its intended application lies in the generation of biological microwave imaging to detect brain tumors. With this objective, the Fractal Slot Edge (FSE) technique was applied with a new fractal developed and based on the Cantor set. The application of this fractal, called Cantor Neogothic Fractal (CNG), formed different-sized cavities resulting, in this work, in three antennas that were analyzed through numerical computational simulation together with AVA. The antennas, called CNG9-FSE-AVA, CNG18-FSE-AVA, and CNG27-FSE-AVA, in which 9, 18, and 27 define the maximum height that the fractal reached in each antenna, have areas equal to 354.66 mm2 , 709.33 mm2 and 1064 mm2 , respectively. All antennas achieved the goal, however, CNG27-FSE-AVA presented the best results at 2 GHz, with a gain of 7.84 dBi, SLL -19.80 dB, and squint of -0.10 degree. Additionally, it was proved that the antenna is suitable to generate a near field microwave imaging of tumors in a brain model.

Abstract

Abstrak - Bagi militer, sebuah sistem yang dapat menawarkan dukungan keputusan dalam proses komando dan kontrol sangatlah dibutuhkan dalam pertempuran, alat yang dapat memberi ruang untuk menjalankan perintah dan kemampuan pengendaliannya selalu menjadi tujuan akhir. Ini bukan hanya karena kompleksitas masalah yang dihadapi saat pertempuran tetapi juga karena kesulitan mendapatkan bantuan dari pengetahuan sebelumnya dan memperluas pengetahuan sebelumnya untuk memecahkan masalah baru. Penelitian ini difokuskan untuk mewujudkan sebuah alat pengkonversi koordinat peta berbasis Raspberry Pi-3 dan bahasa pemrograman Phyton. Dengan meggunakan alat ini diharapkan pasukan militer dapat menentukan koordinat lawan atau kawan secara tepat dan cepat.
