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.

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.

The development of UAV technology has reached the stage of implementing artificial intelligence, control, and sensing. Cameras as UAV data inputs are employed to ensure flight safety, search for missing persons, and disaster evacuation. Human detection using cameras while flying is the focus of this article. The application of human detection in pedestrian areas using aerial image data is used as the dataset in the deep learning input process. The architectures discussed in this study are YOLOv5 and YOLOv8. The precision, recall, and F1-score values are used as comparisons to evaluate the performance of these architectures. When both architecture performances are applied, YOLOv8 outperforms YOLOv5. The achieved performance of YOLOv8 is a precision of 84.62%, recall of 75.93%, and F1-score of 79.98%.

The development of application and network technology is currently so rapid. This technology is widely used as a solution to overcome data inspection problems in the field of Digital Forensics. The importance of Digital Forensics as evidence, especially on computers and mobile devices, is increasing, along with the rapid use of these mobile devices in daily communication. Data and files on computers and smartphones can be deleted intentionally or unintentionally. To recover the data, it is necessary to have Files Recovery. Furthermore, Logical Files Recovery can be made through password encryption, obtained through hack/attack password applications such as Password or even hacked with the "RecoveryMyFile" application. In addition, a search with a file that has a password description can be done. One of the file recovery applications that can be used is the Agent ransack search application, which is more powerful and convenient than Windows Search, which is more complicated if you need to search faster, indexing needs to be done, and restarts. By using Files Recovery analysis, the development of file or data deletion crimes can be overcome with increasingly rapid and advanced information technology, in this case through applications that can be used for file recovery and to restore deleted files.
