Abstract

Abstrak Salah satu bentuk kemajuan di bidang teknologi informasi adalah platform Internet of Things (IoT). Salah satu aspek yang dapat menerapkan konsep ini adalah aspek industri pertanian. Para petani biasanya menggunakan tanah sebagai media tanam, tetapi dalam kemajuan infrastruktur di Indonesia membuat lahan pertanian kian berkurang. Akan tetapi kebutuhan akan pangan harus tetap terpenuhi. Hidroponik adalah salah satu metode budidaya tanaman menggunakan air dan larutan nutrisi sebagai media tanam. Kondisi air dalam hidroponik sangat penting untuk di periksa secara berkala karena berpengaruh terhadap serapan hara dan ketersedian nutrisi, hal tersebut dipengaruhi oleh kondisi pH larutan, konduktivitas listrik, komposisi nutrisi dan suhu. Untuk menghasilkan keputusan yang tepat petani membutuhkan data realtime tentang kondisi air. Pada penelitian ini NodeMCU ESP8266 diimplementasikan sebagai mikrokontroller pada sistem pemantauan kondisi air hidroponik berbasis IoT. Sensor yang digunakan antara lain Sensor Ultrasonik HC-SR04, Sensor Suhu DS18B20, dan Sensor pH E-201C. Data hasil baca dari seluruh sensor dapat di lihat secara realtime di dalam sebuah website yang dapat diakses melalui smartphone.

Abstract The Internet of Things (IoT) platform is a form of advancement in the field of Information Technology applied in the farming industry. Farmers often use soil to grow crops. Though the soil is essential for farming, the use for agriculture steadily reduced because of Indonesia's infrastructure advancement. However, the country's have to fulfill their food needs. Hydroponics is a method of growing crops using water and nutritious solutions as a growing media. In this method, monitoring water conditions from time to time is a must to ensure the crops absorb enough nutrients. The water parameters are pH, electrical conductivity, temperature, and nutritions composition. The real-time values of those parameters are important to decide the treatment of the crop. In this experiment, NodeMCU ESP8266, a microcontroller, was implemented as a monitoring system based on IoT. The sensors for this system are Ultrasonic HC-SR04, DS18B20 temperature sensor, and E-201C pH sensor. The results of all sensors can be accessed in real-time on a website by smartphone. Keywords: NodeMCU ESP8266, Ultrasonic, pH E-201C, Internet of Things, Hydroponic.

Abstract

During a pandemic like now, many workers are being expelled by the company, resulting in a decline in the economy in various regions. To meet the needs of a person may do bad things such as curanmor (motorcycle theft). Even though the motorbike is equipped with a fairly strict security system, it is still sometimes broken by thieves. This study aims to create a motor vehicle security system based on Arduino R3 and RFID as an e-KTP sensor. Where this system can turn on or turn off the motorbike using an ID card or using its RFID Pin. even though the thief managed to break into the ignition, the motor still couldn't start because it needed other access. Based on the results of observations and tests carried out, the authors can conclude that the performance of the motorcycle safety device system using e-KTP works quite well. When the contact is on, it will activate the safety device system before activating the motor electrical system. RFID needs access to the appropriate e-KTP and is forwarded to the microcontroller (Arduino) then produces output to the relay to turn on the motor's electricity so that the motor can be turned on/started
