Abstract

Microplastic contamination in wastewater poses a serious threat to aquatic ecosystems and human health due to its persistence and limited removal by conventional treatment processes. This study evaluates a hybrid photocatalytic membrane reactor (PMR) integrating TiO₂-based photocatalysis with membrane filtration for the removal and degradation of polyethylene (PE), polypropylene (PP), and polyester (PET) microplastics. Photocatalytic membranes were fabricated via phase inversion using polyethersulfone (PES) and characterized by SEM, XRD, contact angle, porosity, and water flux measurements.TiO₂ incorporation significantly increased membrane hydrophilicity and permeability while maintaining the asymmetric structure and anatase crystallinity. The hybrid PMR achieved microplastic removal efficiencies above 99% for all polymers, outperforming membrane-only filtration and standalone photocatalysis. FTIR and SEM analyses confirmed oxidative polymer chain scission, while mineralization efficiencies reached 8.7%, 11.3%, and 18.9% for PE, PP, and PET, respectively. The degradation followed apparent first-order kinetics, with PET showing the highest rate constant. Hydroxyl radicals were identified as the dominant reactive species. The PMR also exhibited mitigated membrane fouling, stable performance over five cycles, and negligible TiO₂ leaching. The specific energy consumption ranged from 0.38 to 0.46 kWh m⁻³ with an estimated operational cost of USD 0.42–0.53 per m³. These findings demonstrate the technical and economic feasibility of the hybrid PMR for advanced microplastic treatment.

Abstract

Peningkatan kasus asam lambung pada remaja dipengaruhi oleh gaya hidup tidak sehat dan rendahnya pengetahuan mengenai pencegahan serta penanganannya, sehingga kegiatan ini bertujuan meningkatkan pemahaman remaja tentang penggunaan bahan alam dalam mengatasi asam lambung. Metode yang digunakan adalah edukasi melalui penyuluhan kesehatan kepada siswa SMA dengan media presentasi, brosur, serta evaluasi menggunakan pretest dan post-test. Hasil menunjukkan adanya peningkatan signifikan pengetahuan peserta dari rata-rata 65,15% menjadi 91,51% setelah diberikan edukasi. Remaja mampu memahami penyebab, gejala, pencegahan, serta pemanfaatan bahan alami seperti jahe, kunyit, sereh, madu, dan pepaya sebagai alternatif penanganan awal. Hasil analisis statistik menggunakan uji Paired T-Test menunjukkan adanya perbedaan yang signifikan antara nilai pretest dan post-test (p<0,001), sehingga edukasi kesehatan berbasis bahan alam dapat meningkatkan pengetahuan remaja mengenai pengendalian asam lambung.

Abstract

This community service activity aims to strengthen Posyandu services in Desa Gondang through the application of early anemia detection technology. Limited access to health examinations has caused anemia to be underdiagnosed in rural communities, especially among pregnant women and vulnerable groups. The implementation method involved technology transfer, participatory assistance for Posyandu cadres, and direct health service activities involving the community. Approximately 137 participants consisting of pregnant women, elderly individuals, and productive-age community members were involved. The results show that Posyandu cadres were able to independently conduct early anemia screening, while the community gained easier access to health examinations and increased health awareness. The activity concludes that the application of appropriate health technology at the community level is effective in improving service quality and supporting sustainable community-based health services.
