Abstract

A computer network is a collection of devices connected to communicate and exchange data. The internet is a global network that connects users worldwide. To access the internet, Mikrotik network devices and LAN cables are commonly used. However, LAN cables are less efficient for multiple users, especially smartphone users, as Android devices do not support LAN connections. Mikrotik offers a hotspot feature that allows users to connect wirelessly. To ensure security and prevent unauthorized access, login authentication is required. This can be achieved by integrating the RADIUS feature on Mikrotik with FreeRADIUS and MySQL on an Ubuntu server. User accounts for authentication can be managed through the daloRADIUS web application. The integration of FreeRADIUS, MySQL, and daloRADIUS with Mikrotik simplifies user account management and prevents unauthorized users from accessing the network. This system enhances security and ensures only registered users are able to access the internet via the hotspot.

Abstract

The development Internet of Things (IoT) technology has been widely used in daily life, especially in the use of electronic devices in homes, such as lights. To create an automatic lighting control system for a room from a distance, a PIR (Passive Infrared Receiver) sensor is needed as input to turn the light on and off automatically based on movement detected in the room. To control the light automatically and connect the devices to the internet, the ESP8266 is used. The results show that the PIR (Passive Infrared Receiver) sensor can detect movement within the room. Thus, the automatic lighting control system can be monitored remotely using a smartphone.

Abstract

Serangan hama tanaman merupakan salah satu faktor utama yang mendegradasi produktivitas padi (Oryza sativa) dan mengancam ketahanan pangan. Identifikasi hama secara konvensional oleh petani sering kali bersifat subjektif, lambat, dan rentan terhadap kesalahan diagnosis. Penelitian ini bertujuan untuk melakukan analisis perbandingan performa antara arsitektur deep learning efficientnet-B0 dan arsitektur berbasis residual block (ResNet-50) untuk klasifikasi hama padi otomatis berbasis visi komputer. Dataset yang digunakan mencakup lima kelas utama, yaitu Wereng Cokelat (Nilaparvata lugens), Ulat Grayak (Spodoptera frugiperda), Rice Hispa (Dicladispa armigera), Walang Sangit (Leptocorisa oratorius) dan Padi Sehat. Pendekatan transfer learning dengan bobot pre-trained dari ImageNet diterapkan untuk mengoptimalkan proses pelatihan pada kondisi data yang terbatas, dikombinasikan dengan teknik augmentasi gambar on-the-fly untuk menyimulasikan kompleksitas latar belakang lahan persawahan. Hasil eksperimen terkontrol menunjukkan bahwa EfficientNet-B0 memberikan performa yang jauh lebih unggul dengan pencapaian akurasi validasi tertinggi sebesar 97,25% dan F1-score 97,65%, dibandingkan ResNet-50 yang hanya mencapai akurasi 95,85%. Inovasi Compound Scaling pada EfficientNet-B0 terbukti efektif dalam mempertahankan fitur-fitur spasial mikro morfologi serangga sekaligus menekan tingkat misklasifikasi antarspesies hingga di bawah 3%. Selain unggul dalam akurasi, efficientnet-B0 menghasilkan ukuran file model akhir yang jauh lebih ringkas, yaitu 25 MB, berbanding terbalik dengan ResNet-50 yang mencapai 98 MB. Penelitian ini menyimpulkan bahwa efficientnet-B0 merupakan arsitektur yang paling optimal untuk diintegrasikan ke dalam sistem pertanian pintar (smart farming) karena menawarkan keseimbangan terbaik antara akurasi tinggi dan efisiensi memori.

Abstract

In this design a tool is made to monitor the quality of water suitable for use using Arduino Uno. This design uses a pH meter sensor which functions to monitor acid levels in water and a turbidity sensor which is used to see the level of water turbidity. The use of these two sensors is based on the suitability of the water for consumption based on the acid level and the level of turbidity of the water. The results obtained in the design show that Arduino can read the acid levels in the water and see the level of turbidity of the water well so that the designed tools can be used directly to monitor the quality of water suitable for use.
