Abstract

Perkembangan pesat infrastruktur jaringan telekomunikasi, seperti Base Transceiver Station (BTS) dan perangkat transmisi, didorong oleh kebutuhan layanan digital dan IoT, namun meningkatkan konsumsi energi listrik yang tinggi. Di negara berkembang seperti Indonesia dengan bauran energi fosil dominan, hal ini berkontribusi signifikan terhadap emisi CO2, memperburuk pemanasan global, sementara implementasi Green ICT masih parsial tanpa kajian empiris terintegrasi. Permasalahan utama meliputi minimnya pemetaan pola konsumsi energi per komponen (BTS 45%, transmisi 24%, pendingin 23%), kurangnya target kuantitatif emisi, persepsi prioritas keandalan layanan daripada efisiensi, serta kesenjangan analisis teknik elektro dan kimia lingkungan. Penelitian bertujuan menganalisis konsumsi energi listrik dan emisi CO pada infrastruktur telekomunikasi dari perspektif teknik elektro-kimia untuk mendorong penerapan Green ICT melalui identifikasi pola, hambatan, dan peluang pengurangan emisi. Metode kualitatif deskriptif digunakan, meliputi wawancara informan kunci, observasi lapangan, studi dokumen teknis, serta estimasi emisi CO2 dengan faktor 0,85 kg CO2/kWh; analisis melalui reduksi data, triangulasi, dan integrasi data kuantitatif-kualitatif. Hasil menunjukkan konsumsi tahunan per klaster ~265.000 kWh menghasilkan 225 ton CO2, dengan potensi pengurangan 20-45 ton melalui upgrade perangkat, penyesuaian AC, dan solar hybrid; praktik Green ICT ada tapi tidak terukur, persepsi teknis vs manajerial berbeda. Disimpulkan bahwa integrasi perspektif elektro-kimia esensial untuk strategi Green ICT berkelanjutan, merekomendasikan target energi-emisi, monitoring rinci, dan komunikasi lintas level demi mitigasi iklim nasional.

Abstract

Water pollution from heavy metals, organics, and pathogens severely threatens ecosystems and public health, yet chemistry education often remains theoretical, limiting students' grasp of wastewater treatment and quantitative reasoning skills. This study aims to enhance undergraduate students' environmental chemistry understanding covering pollutant characteristics, treatment mechanisms, and Anaerobic Baffled Reactor (ABR) functions and mathematical reasoning through data interpretation, calculations, and modeling via Ethnoscience-Project Based Learning (Ethnoscience-PjBL) integrated with ABR, compared to conventional PjBL. Employing a quasi-experimental design with 74 East Java undergraduates (experimental n=38, control n=36), pre/post-tests, N-Gain analysis, normality (Shapiro-Wilk), homogeneity (Levene's), and ANCOVA (pretest covariate) were used. Results showed the experimental group significantly outperformed controls in chemistry understanding (adjusted mean 85.2 vs. 68.8; difference 16.4, Cohen's d=1.48, large effect; F=4.088, p=0.009), achieving 78.9% COD reduction, pH stabilization from 5.2 to 6.8, and robust reasoning. In conclusion, Ethnoscience-PjBL-ABR bridges local wisdom with engineering, fostering integrated cognitive skills for sustainable pollution solutions and warranting adoption in chemistry curricula worldwide.
