Chili peppers are an agricultural product with high commercial value, primarily due to their quality and ripeness. Chili color is the most important indicator for determining ripeness and marketability. However, there are limitations in sorting chili peppers by hand. For example, it is time-consuming, has varying degrees of accuracy, and relies on human effort. Therefore, this study aims to design and develop a prototype of a color-based chili sorting and classification system by combining the TCS3200 sensor with the Internet of Things (IoT). The TCS3200 sensor is used to detect the color of chili peppers. These colors are then processed by a microcontroller to sort chili peppers into green, red, and yellow categories. Classification data is sent and transmitted in real time through an IoT platform, enabling remote monitoring and more effective data analysis. The system is also equipped with mechanical actuators for automatic chili sorting. Tests were conducted to determine the depth of the sensor in detecting color and the system's efficiency in the sorting process. The experimental results show that the system can perform classification with high accuracy and improve sorting efficiency compared to manual methods. This technology is designed to make the chili sorting process faster and more accurate and can be applied on an industrial scale to increase the productivity and quality of agricultural products.

Sistem Pakar Diagnosa Penyakit Ispa Menggunakan Metode Certainty Factor
Respiratory disorders are one of the health problems that can have serious consequences if not properly detected and treated. One of the most common respiratory diseases is Acute Respiratory Infection (ARI). According to data from WHO, ARI is classified as a disease with a high incidence rate and can be fatal if not treated appropriately. Therefore, a system that can assist in the early detection and diagnosis of ARI is needed, one of which is an expert system. An expert system is an artificial intelligence-based system capable of mimicking an expert’s reasoning process in analyzing a disease. One of the methods used in expert systems is the Certainty Factor method. This method has the advantage of handling uncertainty, particularly in diagnosing diseases based on given symptoms. This study discusses the application of the Certainty Factor method in an expert system for diagnosing ARI to support a more accurate and efficient diagnostic process
Implementasi Sistem Kunci Pintar 2FA Berbasis IoT Menggunakan RFID dan Bot Telegram pada ESP32
This study designs and implements a smart keyless prototype with two-factor authentication based on the Internet of Things (IoT) using ESP32, RFID RC522, Telegram bot, relay, and a 12V solenoid lock. The system restricts physical access through two authentication stages: validating the RFID card UID and verifying a one-time password (OTP) sent through the Telegram bot. Testing was conducted in three scenarios: registered RFID with valid OTP, registered RFID with invalid OTP, and unregistered RFID. The results show that the system worked according to the design, achieving 100% success in 10 trials for each scenario under limited prototype testing conditions. The average solenoid activation response time after valid authentication was 0.26 seconds. The prototype can perform basic two-factor authentication according to the tested scenarios, although further security testing is required before deployment in real operational environments.
