Abstract

Clean water is a fundamental necessity; however, many regions still struggle to access it due to contamination by suspended particles, organic matter, and harmful microorganisms. This activity aims to strengthen the practical competence of Biology Education students at Universitas Negeri Medan through training in making simple water filters. The training was conducted through demonstrations and simulations using turbid water from the Tembung River as a sample. The filter was constructed from readily available materials such as used plastic bottles, cotton, tissue, sand, small gravel, and palm fiber arranged in layers. The results showed that the filter effectively reduced water turbidity and enhanced students’ skills in clean water treatment technology. The training also encouraged students to develop 21st-century skills such as critical thinking, problem-solving, and collaboration, while preparing them as future educators capable of raising community awareness about the importance of maintaining water quality. Therefore, this training has the potential to be developed as an applicative environmental education model that contributes positively to clean water provision.

Abstract

Penelitian ini bertujuan untuk menyelidiki tanggapan mahasiswa terhadap konsep childfree dari perspektif Islam. Dengan menggunakan metode kuantitatif, data dikumpulkan melalui kuesioner yang disebarkan kepada 50 responden mahasiswa. Analisis data dilakukan menggunakan skala Likert untuk mengukur persepsi dan pemahaman mereka mengenai childfree dalam konteks ajaran Islam. Hasil penelitian menunjukkan bahwa mayoritas mahasiswa memahami childfree sebagai pilihan individu, tetapi sebagian besar tetap meyakini bahwa pernikahan dan memiliki keturunan adalah bagian dari ajaran Islam yang dianjurkan. Faktor-faktor seperti pemahaman agama, nilai budaya, dan pandangan sosial berperan dalam membentuk opini mahasiswa mengenai childfree. Oleh karena itu, penelitian ini memberikan wawasan mengenai bagaimana mahasiswa Muslim memaknai childfree dan implikasinya dalam kehidupan sosial serta keagamaan mereka.

Abstract

Zinc (Zn) is one of the most common heavy metal contaminants found in industrial wastewater and solid residues such as slag, electroplating waste, and metal ash. At excessive concentrations, Zn can cause environmental disturbances, including toxicity to aquatic organisms, disruption of microbial activity, and groundwater contamination. Long-term exposure may also lead to bioaccumulation and potential health risks to humans. This article presents a comprehensive literature review that discusses the chemical properties of Zn, its environmental behavior, and the development of recent treatment technologies within the last five years. Several techniques, including adsorption using modified or composite materials, biosorption utilizing microalgae and agricultural biomass, as well as solidification–stabilization with amendment agents such as biochar or iron-sulfide compounds, are evaluated and compared. The literature indicates that no single treatment method is universally effective for all waste types; therefore, hybrid or integrated treatment systems are considered more efficient and sustainable. Based on the reviewed evidence, this study proposes an engineering concept that emphasizes environmental safety, cost-effectiveness, and industrial applicability.
