Hal ini dikarenakan keuntungan yang diperoleh dari penjualan ikan koi sangat menjanjikan. Faktor utama berhasilnya penjualan ikan koi adalah kualitas ikan dari hasil budidaya itu sendiri. Untuk mendapatkan hasil budidaya berkualitas, tentunya kolam-kolam tersebut harus selalu dalam keadaan bersih (memiliki tingkat kekeruhan air < 400 NTU). Oleh karena itu dibuatlah suatu sistem untuk dapat memonitoring tingkat kekeruhan air dan pemberi pakan otomatis pada kolam budidaya ikan koi dengan tujuan membantu pembudidaya ikan koi meningkatkan kualitas hasil budidaya mereka. Prinsip kerja sistem monitoring tingkat kekeruhan air kolam budidaya koi ini adalah dengan membaca nilai kekeruhan air kolam menggunakan sensor kekeruhan (Turbidity Sensor). Pembacaan nilai sensor tersebut akan diproses mikrokontroler NodeMCU kemudian mengaktifkan modul relay pompa drainase untuk menguras air keruh. Di...

Every year in Indonesia and other countries experience a continuous increase in the number of cars. The intensity of cars especially in parking areas often become a challenge for drivers to park cars and increases the risk of a crash. This research aims to design and build a distance sensor device that helps to park cars based on Arduino Uno microcontroller which is hoped to help decrease the risk of cars crashing to another car or object. This device will will produce three types of input that will inform the driver on the distance detected, between the car and another object. The first output is in text form displayed on an LCD screen, then the second output is a buzz produced by a buzzer and the third output is produced by a speaker which produces sound of audio recordings voicing the distance detected by the sensor.

Negligence in turning off lights and air conditioners in class is one example of the waste of electricity that occurs in school and campus institutions. By using the PIR (Passive Infra Red) sensor and LDR (Light Dependent Resistor) on the automatic control system of lights and air conditioners, it is expected to reduce excess electricity consumption. All uses of sensors are connected directly to Arduino Nano as the center of automatic system controllers. Software design uses the basic programming language C Arduino and utilizes the timer library function which functions as a room timer. From the results of the research, this tool can already be used as an automation while saving electricity consumption in the use of electronic devices such as lights and air conditioners.

Taekwondo comes from Korea, Tae means "kicking or destroying with legs"; Kwon means "boxing"; and Do means "road" or "art". The taekwondo match is led by a referee and a judge who is responsible for giving scores to athletes who get points. During taekwondo match training, the assessment is still done in a manual way so that electronic score equipment is needed that is portable and easy to operate. Based on this, there is a desire to make electronic score equipment used for taekwondo match training by creating a scoring board using an Arduino-based joystick. The Arduino-based scoring board uses two PS3 sticks that are connected to Arduino wirelessly using Bluetooth and received by the joystick receiver.
