Simulasi Pemograman Pengendali PWM Kecepatan dengan Mikrokontroler Arduino berbasis Sensor Ultrasonik HC-SR04 pada Purwarupa Mobil Listrik
Get PDFThe braking process is the basis in the making of the PWM speed control system in order for electric cars to be able to stop automatically and increase the driving safety. The usage of an electric motor as a wheel drive for an electric car allows controlling with a microcontroller. Based on the journal about electric motor control, it is necessary to study the use of PWM as a speed controller. The C language as a coding language can be understood by the Arduino microcontroller with the aim of regulating the speed of the electric motor. The research objective was to use the C language programming as a PWM speed controller with the Arduino microcontroller. The methodology used in this study was to modify a remote control car (RC) made as a prototype electric car. The Arduino microcontroller system was installed and programmed in C language as a PWM speed controller. The main sensor tool used was the ultrasonic distance sensor as the microcontroller input data. Direct current (DC) motors on RC cars were regulated with a pulse width modulation (PWM) signal as the output from the Arduino. LCD and buzzer were used as display devices and indicators of safe distances between prototypes and obstructions. The test results showed that the detection distance of the ultrasonic sensor reached 2 cm to 500 meters. Then the acceleration data obtained by pulse width modulation 64 at 1 meter distance, 127 at 3 meter distance, 191 at 4 meter distance, 225 at 5 meter distance and was made in graphic form. In a speed control system, the usage of the Arduino UNO microcontroller was easy to apply and had complete features. The series of speed control systems could be applied to electric cars with the PWM slow reduction criteria in two stages. The PWM lowering process took 1 second after the sensor detects an obstruction object

Implementasi Electronic Customer Relationship Management pada Aplikasi Layanan Pelanggan Hotel
Get PDFThe interest of hotel visitors has decreased since the Covid-19 pandemic. So it is recommended that hotels implement Customer Relationship Management (CRM) which has three stages: getting new customers (Acquire), improving customer relationships (Enhance), and retaining customers (Retain). However, hotels currently do not have practical service applications that help to maintain the relationship between hotel management and consumers, so it requires research that implements E-CRM by designing a prototype of web-based Hotel customer service applications. This study aims to standardize hotel customer service applications that implement E-CRM. It uses qualitative research methods by applying the prototype system development method. The research contribution is to make an E-CRM prototype in a hotel customer service application with several features such as complaints, testimonials, promotions, and point redemption. Based on experiments and testing from a user using UAT and interview, the implementation of E-CRM using a prototype of web-based Hotel customer service applications helps the staff to find customer complaints. The promotion feature helps staff add promotional information that appears on the website\u27s front page. Hotel customers can use the feedback feature in complaints, testimonials and redeem points exchange with prizes. In future research, sentiment analysis on hotel customer reviews using a classification algorithm can be carried out

Desain Alat Smart Farming Penyiram Bawang Merah Menggunakan Arduino Uno Berbasis Android
Get PDFOne of the technological developments in agriculture is smart farming. Shallot farmers still carry out the process of watering shallot plants manually. This takes a long time because farmers have to go around the agricultural land during the watering process. To solve these problems, an automatic shallot sprinkler machine was designed that can be applied by farmers. The Arduino Uno ATMega328 microcontroller is used on this machine as the control system, while Android is used for the interface. The android interface on this machine can provide a graphical display, therefore farmers can give direct orders to drive a DC motor (Direct Current) and a DC pump on/off switch (Direct Current). The results of the smart farming research on this automatic onion sprinkler help farmers get 72% efficient time. The comparison can be seen in the manual watering process on 10,000m2 agricultural land that takes 7 days, on the other hand, it only takes 2 days when it is done with smart farming technology.Salah satu perkembangan teknologi dalam pertanian adalah smart farming.
