Abstract

Purpose: This study addresses the challenge of ineffective organic waste management in Indonesia by developing a technology-driven, community-based model. Method: An integrated system was implemented at an Integrated Waste Processing Facility (TPST), featuring an automatic sorter using color, infrared, and weight sensors, combined with an anaerobic bioreactor for biogas production. The process was monitored through an IoT platform for real-time control. Practical Applications: The system improved sorting efficiency and reduced processing time, while community training increased household waste segregation participation from 15% to 48%. Conclusion: The model achieved 92% sorting accuracy and produced an average of 22 m³ of biogas per ton of waste, demonstrating that combining automation with social empowerment creates an effective and replicable solution for sustainable waste management and renewable energy transition.

Abstract

A real-time biogas monitoring and control system was developed by integrating the K-Nearest Neighbor (KNN) algorithm into an IoT-based framework for methane pressure prediction and automated control. The system uses an ESP32 microcontroller connected to temperature, gas, and pressure sensors (DHT22, MQ-4, MPX5700) to continuously collect data, with cloud connectivity provided through Firebase and Blynk platforms. The predictive model operates within a live feedback loop, allowing immediate actuation based on forecasted methane conditions. With an optimal parameter of k=4, the KNN model achieved 93.33% accuracy, supported by a mean absolute error (MAE) of 0.18 and a root mean square error (RMSE) of 0.21. A comparative evaluation with Random Forest and Gradient Boosting algorithms showed that, although these models yielded slightly higher accuracy, KNN provided superior computational effi-ciency for embedded deployment. The system maintained stable operation during tests involving sensor anomalies, network interruptions, and data noise. However, redundancy mechanisms and improved vali-dation strategies are recommended to enhance robustness. The findings demonstrate that methane pro-duction can be effectively predicted using temperature and pressure data, with further accuracy im-provements possible through additional process variables such as pH and fermentation age.

Abstract

The broiler poultry industry significantly contributes to food security by supplying animal protein; however, it also generates harmful gases such as ammonia (NH?) and methane (CH?) from accumulated waste. These gases not only endanger poultry health but also contribute to environmental pollution and climate change. This research proposes the development of an Internet of Things (IoT)-based monitoring and control system for ammonia and methane gas levels in broiler chicken farms. The system employs MEMS NH? and MQ4 gas sensors integrated with an ESP32 microcontroller, and applies the Mamdani fuzzy logic method to classify gas levels into safe, unhealthy, or dangerous categories. Based on the fuzzy output, a water pump powered by a hybrid solar energy system is activated automatically to reduce gas concentrations. Data is transmitted in real-time to a Firebase database and can be accessed via an Android application supporting both manual and automatic control modes. Experimental results demonstrate the system's effectiveness in detecting gas levels accurately and responding efficiently to maintain a healthy farm environment while utilizing renewable energy sources.

Abstract

The design and implementation of an intelligent biogas quality monitoring and control system that combines machine learning, actuator automation, and Internet of Things (IoT) technology is presented in this research. The system uses a thermocouple type K, MPX5700, MQ-4, and MQ-135, among other environmental sensors, to measure temperature, pressure, CO?, and CH? in real time. An ESP32 microcontroller processes sensor data using the Gaussian Naïve Bayes algorithm to categorize biogas quality into three classification, namely Good, Moderate, and Poor. A servo motor is utilized to control a valve that either permits or prohibits the flow of biogas to a generator based on the classification output. Through the Blynk IoT platform, the system has the capacity to be remotely monitored. Results from experiments with 40 biogas data demonstrated that the system had good precision and recall in each category and an overall accuracy of 92.5%. The approach exhibits dependability, affordability, and suitability for community-based biogas management in rural and semi-urban evironments.

Abstract

Pengelolaan menjadi tantangan dengan jumlah sampah secara global mencapai 2,01 miliar ton per tahun, dan angka tersebut diproyeksikan meningkat menjadi 3,40 miliar ton pada 2050. Di Indonesia, sekitar 38,38% dari 38,4 juta ton sampah nasional pada 2023 masih belum terkelola dengan baik, yang memicu berbagai dampak negatif terhadap lingkungan dan kesehatan. Rendahnya tingkat pemilahan sampah di tingkat rumah tangga menjadi hambatan utama dalam sistem pengelolaan sampah. Penelitian ini mengembangkan sistem cerdas berbasis Artificial Intelligence of Things (AIoT) untuk pemilahan sampah otomatis menggunakan model YOLOv8. Metode yang diterapkan mencakup klasifikasi jenis sampah (organik, anorganik, B3, dan lainnya) dengan deteksi berbasis visi komputer dan pengukuran kapasitas menggunakan sensor ultrasonik. Hasil pengujian menunjukkan bahwa model klasifikasi YOLOv8 mendapatkan nilai Macro F1-Score sebesar 63,9% dalam identifikasi sampah. Sensor ultrasonik memberikan data akurat mengenai kapasitas sampah secara real-time, meningkatkan efisiensi pemantauan. Sistem ini terintegrasi dengan Website untuk memfasilitasi akses informasi secara otomatis dan mendukung pengelolaan sampah berkelanjutan. Penelitian ini memberikan solusi inovatif dalam meningkatkan efisiensi pengelolaan sampah melalui teknologi AIoT, yang dapat berkontribusi signifikan dalam mitigasi masalah sampah global.
