Abstract

The stability of the microclimate in the cage is a necessity in quail farming, since the temperature and humidity directly influence the comfort, growth, health and egg production of the animals. Manual monitoring is limited by farmer availability, reaction times, and inconsistent observations, particularly in the context of rapid environmental change. This work describes the development of an Internet of Things (IoT)-based temperature and humidity monitoring and control system with the K-Nearest Neighbors (K-NN) algorithm to categorize the quail cage environment states and to facilitate autonomous actuator management. The system was designed utilizing ESP32 microcontroller, DHT22 sensor, Incandescent bulb, Blower, Firebase real time database and a monitoring application based on Flutter. The temperature and humidity data were collected from the cage environment, identified by K-NN according to the established environmental classes and used to determine actuator responses. The experimental findings indicated that the system could monitor the cage conditions in real time and operate the lamp and blower according to the intended control logic. The DHT22 sensor produced an average temperature error of approximately 3.77% and an average humidity error of approximately 7.04%. The real-time monitoring delay ranged from 1 to 4 seconds, with an average delay of about 2 seconds. In preliminary classification testing, the K-NN results showed full agreement with manual decisions for the tested samples. These findings indicate that the developed IoT and K-NN-based system can support more efficient quail cage microclimate management and provide a practical low-cost smart farming solution for small-scale poultry farmers.

Abstract

Melon cultivation requires appropriate light intensity and photoperiod management because light directly affects photosynthesis, vegetative growth, and plant productivity. In conventional cultivation, additional lighting is often controlled manually, making it less adaptive to changes in sunlight intensity, temperature, and daily photoperiod. This study develops an Internet of Things (IoT)-based automatic light intensity control system using the Fuzzy Sugeno method to optimize photoperiodism in melon plants during the vegetative phase. The system integrates an ESP32 microcontroller, BH1750 light intensity sensor, DHT21 temperature sensor, real-time clock, AC light dimmer, LED grow light, LCD I2C, and Blynk application. The Fuzzy Sugeno method was implemented to determine the percentage of LED grow light output based on light intensity, temperature, and daily time period. Experimental results showed that the BH1750 sensor calibration reduced the average measurement error from 10.13% to 2.753%, while the DHT21 temperature sensor calibration reduced the average error from 3.95% to 0.31%. The AC light dimmer responded proportionally to PWM input, producing lamp outputs from 0 lux to approximately 28,000 lux. Data transmission to Blynk was successful with an average delay of about 1.01 seconds. Plant testing for 14 days showed that the IoT-based automatic lighting system produced better vegetative growth than the conventional method, with plant height reaching 19 cm and five leaves. These findings indicate that the developed system can support adaptive lighting control for melon photoperiodism optimization.

Abstract

Language barriers remain a significant challenge in the tourism sector, particularly in Indonesia, where communication between international tourists and local service providers often faces difficulties due to limited English proficiency. Existing translation tools, such as mobile apps and standalone devices, suffer from limitations like reliance on internet connections, one-way communication, and the need for additional devices. This research aims to develop a smart glasses prototype that integrates speech recognition, Long Short-Term Memory (LSTM)-based translation, and speech synthesis technologies to offer real-time, bidirectional communication. The prototype development involved several stages: literature review, design, tool collection, prototyping, and testing using the Tatoeba dataset, which includes 13,570 English-Indonesian sentence pairs. The smart glasses prototype was tested for translation accuracy, speech recognition, and synthesis performance, yielding BLEU scores of 36.5% for Indonesian-English and 39.8% for English-Indonesian, with accuracy rates of 80.8% and 87.8%, respectively. The prototype demonstrated effective real-time translation with speech-to-text and text-to-speech functionalities. These results show that the smart glasses prototype can significantly improve the quality of communication between tourists and local communities, enhancing the competitiveness of Indonesia's tourism industry. The study implies that wearable translation devices could become essential tools in tourism, reducing language barriers and fostering better cross-cultural interactions.
