Abstract

In poultry farming, particularly for Day-Old Chicks (DOC), maintaining an ideal environmental condition is a significant challenge due to the limited ability of mother hens to provide adequate warmth and care. This often leads to a high mortality rate among DOC, especially in broiler chickens. The research contribution is the development of an intelligent incubator system based on fuzzy logic to automate environmental control and reduce DOC mortality rates. The system employs a DHT22 sensor to measure temperature and humidity, and an MQ-135 sensor to detect ammonia levels. An ESP32 microcontroller is used for data processing, chosen for its built-in Wi-Fi capability and high processing power. The DHT22 sensor controls a fan and UVA+UVB lamp via an AC dimmer, while the MQ-135 sensor controls a DC motor through the L298N driver. The fuzzy logic method is applied to make more accurate control decisions, and the entire system is connected to an IoT-based monitoring platform that provides a real-time dashboard for farmers. Preliminary results show that the system successfully maintains temperature within the optimal range (30–34?) and humidity (40–70%), and responds efficiently to changes in ammonia concentration. Compared to conventional systems, this intelligent incubator offers better automation, lower energy consumption, and cost efficiency. In conclusion, the proposed system provides a scalable and efficient solution for DOC management. Future work includes AI-based prediction integration, mobile application development, and historical data analysis for smarter poultry farm management.

Abstract

The development of a microstrip antenna for digital TV applications at the center frequency of 598 MHz has been carried out to meet the needs for optimal signal reception in urban areas such as Surabaya. In this research, a microstrip antenna is designed, simulated, and fabricated to verify its performance. The simulation results show that the antenna has a return loss of -12.27 dB, VSWR 1.639, bandwidth 359 MHz, gain 2.26 dBi, and an omnidirectional radiation pattern. After the fabrication process, antenna performance measurements show a return loss of -25.78 dB, VSWR 1.849, and bandwidth 154 MHz. Discrepancies between simulation and fabrication results are mainly due to manufacturing tolerances and material variations. Nevertheless, the results obtained show that the developed microstrip antenna has good performance and is suitable for digital TV applications at the targeted frequency, with the ability to receive signals omnidirectionally which is very important in dense urban environments.
