Abstract

This study adopts a mixed-methods approach, combining qualitative and quantitative techniques, to evaluate household hazardous waste management practices. Data were collected through surveys, in-depth interviews, and direct observations. Quantitative data were analyzed using descriptive statistics to measure community awareness levels and the effectiveness of waste management infrastructure, while thematic analysis was applied to qualitative data to identify key issues and patterns in community behavior. The findings highlight the effectiveness of community empowerment programs in improving knowledge and practices, with recognition of hazardous waste types increasing to 85%, understanding of associated hazards to 82%, and a reduction in littering behavior from 65% to 20%. These results underscore the importance of multi-stakeholder collaboration, infrastructure enhancement, and the integration of circular economy principles to achieve sustainable waste management. The study provides actionable, data-driven recommendations for reducing health and environmental risks associated with hazardous waste, emphasizing the need for continuous monitoring and community engagement.

Abstract

The post-pandemic shift in education has accelerated the adoption of hybrid learning, which integrates both online and face-to-face instruction. Within this setting, indoor air quality (IAQ) plays a vital role in affecting students’ comfort, health, and productivity. This study investigates the relationship between IAQ and student productivity in the hybrid learning era. A quantitative approach was employed using a correlational survey design, involving several schools selected through purposive sampling. IAQ parameters measured included carbon dioxide (CO₂), temperature, relative humidity, and particulate matter (PM2.5 and PM10), using standardized digital instruments. Student productivity was evaluated via a structured questionnaire addressing concentration, focus, and academic performance. Descriptive analysis revealed that average levels of CO₂ (1185.6 ppm), PM2.5 (41.7 µg/m³), and PM10 (64.2 µg/m³) exceeded health standards, whereas temperature (28.3°C) and humidity (61.2%) remained within moderate limits. Productivity scores were in the fair-to-good range (average concentration 3.7; focus 3.5; academic achievement 77.8), with notable differences observed across classes. Pearson correlation analysis indicated significant negative associations between CO₂, PM2.5, and PM10 with all productivity indicators (p < 0.05). Multiple linear regression identified CO₂ (β = -0.412) and PM2.5 (β = -0.387) as the most influential factors in reducing student productivity. These results suggest that poor indoor air quality, particularly elevated CO₂ levels and fine particulate matter, is a key determinant that can impede the effectiveness of hybrid learning.
