Perspektif Analisis Pengujian Kualitas Air Sungai sebagai Bahan Pembelajaran Aplikatif Green Chemistry di Kelas X

Abstrak

The purpose of the study, Perspective of River Water Quality Analysis as an Applied Green Chemistry Learning Resource for Grade X Students, was to assess how wastewater from the beverage industry affects river water quality and investigate its use as a contextual learning resource in green chemistry education. An integrated location sampling technique was used in a quantitative descriptive approach. Water samples from the river's upstream, midstream, and downstream segments were gathered, combined, and examined for colour, odour, turbidity, pH, and Chemical Oxygen Demand (COD). The results revealed thbehaviourver water was brownish, muddy, and had an unpleasant odour, indicating low water quality. Chemical examination indicated a pH of 6 and a COD content of 8,000 mg/L, indicating significant pollution from organic and inorganic toxins resulting from industrial activity. The high COD concentration indicates a significant oxygen demand for pollutant oxidation, posing a risk to aquatic ecosystems. These findings show that river water quality analysis can be a valuable contextual learning resource for Green Chemistry, increasing students' environmental awareness, critical thinking skills, and understanding of sustainable chemical practices while encouraging environmentally responsible behaviour.
