Abstract

The importance of pet adoption is very important in efforts to support the prevention of animal abandonment. Currently, the pet adoption system in Indonesia still largely relies on a manual approach. This process is carried out directly without paying attention to important aspects of the match between the pet and its adopter, which can result in a lack of information which has a long-term impact on the abandonment or return of the pet. Based on these problems, this research aims to design and create an application that can facilitate the pet adoption process. This application was built for Android-based mobile devices by utilizing Machine Learning methods to provide personalized pet recommendations based on user preferences using Content-Based Filtering and making it easier to identify pet breeds from photos uploaded or selected by users using Image Classification. The pet data collected was sourced from the Kaggle, TensorFlow, and GitHub websites. It is hoped that the results of this research can overcome the problem of pet adoption in a better and more sustainable way and will not only provide benefits for abandoned animals, but can also reduce cases of animal abandonment due to irresponsible owners.

Abstract

Unbalanced intersectional traffic flow increases vehicle delays, fuel consumption, and pollution. This study investigates the application of deep reinforcement learning (DRL) to optimize traffic signal timing at the Pamelisan intersection in Denpasar, Indonesia. Real-world traffic data were incorporated into a SUMO microsimulation environment to train DRL agents using the deep Q-network (DQN) algorithm. Experimental results show that DRL-based optimization reduced the average vehicle waiting time from 594.49 seconds (static control) to 169.44 seconds and 173.10 seconds for agents trained without and with noise, respectively. The average vehicle speed remained stable at 5.6–5.97 m/s across all scenarios, indicating enhanced traffic efficiency without adverse effects. The findings underscore the effectiveness and adaptability of DRL in addressing traffic inefficiencies, optimizing them, and offering a robust solution for dynamic traffic management at unbalanced traffic intersections in urban areas.

Abstract

Urban agricultural land conversion encourages the use of hydroponic systems. However, people's busy lives make it difficult to monitor the nutrition and environment of hydroponic plants. This study developed a monitoring system called Hydrotech, an IoT-based hydroponic monitoring system with an ESP32 microcontroller and pH, TDS, temperature (DS18B20), and water level sensors. Data from the sensors is sent to Firebase and displayed through a mobile application. The method used is an experiment and literature study. Testing was carried out by planting lettuce using the Hydrotech system to evaluate its performance. Primary data was obtained from device testing which includes data from research on the sensors used, while secondary data was obtained from previous research sensor data as a comparison with the current study. The results of this study indicate that the four sensors used, namely the pH, TDS, water level, and temperature DS18B20 sensors, can function properly. Hydrotech is also equipped with an Android application to display sensor data in real time and present historical data for each sensor used for further analysis on hydroponic plants. The Hydrotech application is also filled with a planting calendar as a reminder of planting and harvesting times for hydroponic plants. This Hydrotech monitoring system helps city residents manage hydroponics optimally and efficiently in terms of both energy and time.
