Abstract

Advances in science and technology play a role in realizing a better human life. one of them is theadvancement of electronic technology that has been inherent in human life. Studying diligently is anobligation of a learner, not only to pursue an achievement, but learning also helps to be more focusedon doing something. However, not a few people easily experience fatigue in studying, one of which isfatigue in the eyes, this fatigue arises due to the lack of lighting in the room where we study. Lightingrequirements are regulated based on the decree of the minister of health No. 48 of 2016 regarding theamount of irradiation needed to be able to carry out activities effectively and SNI 6197: 2020 wherevarious kinds of activities and work carried out have the required lighting standards. In this study,looking for the set point value and the amount of lux needed to be accessible through the androidapplication, looking for the amount of pwm value needed for each % of the manual setting of thelamp, and looking for the size of the voltage input measured in each test.

Abstract

Motorcycles are two-wheeled vehicles that are very common and widely used in Indonesia. At the same time, the criminal rate of motorcycle thieving also has the possibility to increase. The standard security system that motorcycles have is still ineffective. One solution to secure motorcycle from theft is adding a security system. The security system used in this research is a tracking system using a Quectel L80-R GPS connected to an ESP8266 NodeMCU which then installed on a motorcycle. The GPS then integrates with the Telegram application. Users can request the location of the motorcycle by pressing the button on the Chatbot that was previously created. Then the GPS will send a link containing the coordinates of the motorcycle location which can be opened via Google Maps. In this research, the location obtained from the GPS response is quite accurate with an average error distance of 3,06 meters in outdoor tests and 3,51 meters in indoor tests with each 30 trials in 3 different places. Thus, the tracking system using Quectel L80-R GPS can be used properly as a motorcycle security system and has been integrated with the Telegram application.

Abstract

Abstract  This study aims to design and construct an Arduino- based HC-Sr04 Ultrasonic sensor in reducing the spread of Covid- 19 in this new normal era. The ultrasonic sensor will be used as a device that can detect the presence of object in front of it by utilizing ultrasonic waves emitted by the transmitter on the sensor. Through these advantages, the device is used as a warning medium to keep a distance according to the Covid-19 prevention protocol in the new normal era. As is often campaigned, social distancing is one of the efforts that greatly affects the spread of the corona virus, so that through the design and implementation of this system, it is hoped that this can be achieved. In the research process, an ultrasonic sensor is used to measure distance, then the data will be sent to Arduino as the microcontroller or brain of this system. Simply put, when the object approaches the sensor at a predetermined distance limit, Arduino will process the data and then immediately give a command to activate the buzzer. The results of the research carried out are a product of automatic distance limiting technology using the HC-Sr04 ultrasonic sensor based on Arduino Uno which of course can provide benefits, especially in a pandemic situation like today.Keywords: Ultrasonic HC Sr 04, Arduino, Covid-19, New Normal

Abstract

Perkembangan teknologi yang semakin maju khusus nya bidang elektronika dapat dimanfaatkan dari segala bidang salah satu contohnya yakni perangkap tikus otomatis dengan memanfaatkan teknologi IoT yang dapat mempermudah pekerjaan manusia menjadi mudah dan efisien. Tingkat pertumbuhan tikus pada daerah padat penduduk sangat tinggi dikarenakan tidak ada nya predator alami. Untuk mengatasi hal tersebut dibutuhkan inovasi agar dapat mengurangi tingkat pertumbuhan populasi tikus pada daerah padat penduduk.  Dengan memanfaatkan teknologi IoT , perangkap tikus konvensional dengan pengendali pintu otomatis dan pengendali relay untuk menyetrum , diharapkan dapat menjadi alat bantu dibandingkan dengan perangkap tikus konvensional. Cara kerja dari perangkap adalah dengan menggunakan arduino uno sebagai mikrokontroler dan NodeMcu untuk menghubungkan perangkap dengan device user untuk mengirimkan informasi bila ada objek yang masuk kedalam perangkap, jadi user tidak perlu repot untuk memeriksa secara manual. Perangkap dapat dipantau dari jarak jauh selama perangkap nya terhubung dengan WiFi..

Abstract

Transmisi pada energi listrik merupakan sistem energi listrik tegangan tinggi hingga tegangan rendah. CVT bagian alat proteksi dari sistem transmisi yang ada pada Gardu Induk yang berfungsi sebagai penyambung antara pembangkit listrik dengan distribusi seperti Gardu Induk sebelum disalurkan ke beban yaitu konsumen. Pada Gardu Induk juga bekerja untuk menaikkan atau menurunkan tegangan listrik dan sebaliknya. Maka dari itu, instalasi Gardu Induk merupakan objek yang vital dalam menyalurkan energi listrik sampai ke tangan konsumen. Terdapat banyak komponen dalam lingkup Gardu Induk untuk kinerjanya, salah satunya seperti Tranformator dan Capacitive Voltage Transformer (CVT) berfungsi untuk alat pengaman yang dapat mengubah tegangan listrik  dari tegangan tinggi menjadi tegangan yang lebih rendah untuk menjamin dan memastikan tenaga listrik berjalan sesuai standarisasi, maka dilakukan pemeliharaan salah satunya melakukan pengujian tahanan isolasi dalam upaya meningkatkan proteksi pada alat menjadi perhatian khusus pada komponen di Gardu Induk.  Capacitive Voltage Transformator (CVT) adalah salah satu peralatan inti di gardu induk, maka dari itu penelitian ini memberikan pengetahuan pemeliharaan CVT untuk menjaga sistem proteksi kinerja CVT itu sendiri masih layak digunakan atau tidak secara keseluruhan dengan melakukan 2 pengujian, pengujian terhadap pentanahan dan isolasi.

Abstract

Abstract  The interconnectedness of the times includes all aspects, one of which is the temperature of the earth which is getting warmer, the annual prediction of increasing by 1 ° to 1.5 ° Celsius. In addition, there are technological updates with ideas that are a daily necessity. Evaporative Cooler is a conventional air conditioner throughout the world with various types and types, DEC (Direct evaporative Cooler), for example works by converting sensible heat into latent heat, whose main circuit consists of an electric motor, swing cooler motor and 24V DC water pump, a actuator module used in the implementation of this system. The idea that came up was that not many people paid attention to the system its use. This research will apply one of the wireless communication, namely the Bluetooth HC-05 Module in the control model design using ECOSYSTEM (Evaporative Cooler System) where the input is integrated with an artificial application installed on a smartphone with Bluetooth devices in it with the android operating system so that it can communicate between systems. Focusing on the communication performance applied by the HC-05 with a 2.4GHz frequency as a receiver or sender of commands with a range of signal distances that can be given, equipped with an Arduino UNO ATMega328 microcontroller for core system controllers. Over-the-air communication model that does not require other media devices in the process of working. Measurement of the performance of the signal coverage is proven horizontally and vertically, intended because there is a difference in the capture power of the transceiver and receiver signals as well as the conditions when bluetooth is controlled, it is connected and not yet connected. In the test, bluetooth only captures two conditions when it is working, when it is still affordable, bluetooth will connect and remain connected with a delay of not more than 0.02 seconds or not connected at all when the range is getting farther.
