Abstract

Air pollution around Benda Sub-district, Tangerang has become a critical environmental issue due to the high intensity of traffic transportation and industrial activities that contribute to the emission of harmful gases. Prolonged exposure to air pollutants poses significant health risks, including adverse effects on the human immune system, particularly for communities residing. This study aims to examine the immune response, specifically leukocyte differentials (neutrophils, eosinophils, monocytes, basophils, lymphocytes) and C-Reactive Protein in individuals aged 25–35 years living in densely populated settlements. A cross-sectional approach was employed involving 24 volunteer participants, accompanied by air quality measurements at the sampling location, including TSP, SO₂, NO₂, Pb, CO, Ox, NMHC, PM₁₀, and PM₂.₅. The results highlighted the high MCV levels in all participants could causing the basic inflammatory response in the body. Furthermore, this study revealed that air pollution exposure indirectly affects the immune system.

Abstract

In the modern digital era, the concept of waste extends beyond the physical realm and into the digital domain, manifesting as redundant data, excessive computation, and continuous processing of unnecessary signals. This study introduces the application of zero-waste thinking to Digital Signal Processing (DSP), with a focus on minimizing computational, data, and energy waste in always-on audio systems. A lightweight, energy-aware Voice Activity Detection (VAD) method is proposed, utilizing signal energy and zero-crossing rate (ZCR) features to intelligently activate or suppress processing based on speech presence. MATLAB-based simulations were conducted to evaluate system performance under various noise conditions, measuring computational load, activation efficiency, and detection accuracy. The results show that the proposed approach significantly reduces unnecessary processing while maintaining reliable speech detection. This work offers a practical framework for sustainable and efficient DSP, contributing to the emerging paradigm of digital zero-waste systems.
