Methane (CH4) is a highly flammable and potent greenhouse gas, wich has produced in landfills through the anaerobic decomposition of organic waste. Supit Urang Landfill in Malang receives approximately 500-700 tons of waste per day. Studies indicate that such daily waste input may result in methane emissions ranging from 8 to 12 tons per day, depending on the organic fraction and environmental conditions. This contributing to significant CH4 emissions that pose risks of fire, air pollution, and climate impact. Although a fixed gas capture system exists, emissions in uncovered areas and limitations in static monitoring systems hinder reliable detection and response. This study proposes a mobile multi-sensor system for real-time methane and air quality monitoring using a grid-based measurement approach. The system integrates gas and environmental sensors including MQ-4, MQ-135, TGS2611, MH-Z19B, PMS5003, HTU21D, and GPS mounted on a mobile robot platform. The robot navigates predefined paths, collects data at each node, and transmits readings to a cloud server while keeping local backups. Experimental results show that improved spatial coverage, consistency, and operational safety compared to static systems. The method offers a scalable and cost-effective solution for landfill monitoring, supporting early warning systems and more informed waste management decisions. © 2025 IEEE.
