Abstract

The well water in Bajarum Village contains high levels of dissolved iron (Fe), requiring filtration using Malang Sand. This study aims to analyze the effectiveness of Malang Sand in reducing Fe levels with varying filter media volumes. An experimental method was employed using two filtration systems that combined aeration and filtration techniques. Groundwater samples were collected from several wells and tested for Fe levels before and after filtration. The results showed that the filter with 50% Malang Sand reduced Fe by an average of 11.7 mg/L (73.87%), while the filter with 100% Malang Sand reduced Fe by an average of 15.69 mg/L (91.16%). Statistical analysis confirmed a significant reduction in Fe levels after filtration (p<0.05); however, no significant difference was found between the 50% and 100% media volumes (p>0.05). In conclusion, Malang Sand filtration effectively reduces Fe levels, but increasing the media volume does not result in a significant difference.

Abstract

Air adalah merupakan sumber daya alam yang diperlukan untuk hajat hidup orang banyak, bahkan oleh semua makhluk hidup. Oleh karena itu sumber daya air harus dilindungi agar tetap dapat dimanfaatkan dengan baik oleh manusia serta makhluk hidup yang lain. Sungai merupakan sumber daya alam yang bersifat mengalir (flowing resources), sehingga pemanfaatan air di hulu akan menghilangkan peluang di hilir. Pencemaran dihulu sungai akan menimbulkan biaya sosial dihilir (extematily effect) dan pelestarian di hulu memberikan manfaat di hilir. Kegiatan stockpile pertambangan batubara PT. Nantoy Bara Lestari di Kabupaten Barito Utara yang terduga berubahnya kualitas dan baku mutu air Sungai Pendreh, perubahan sifat fisik kimia air. Metode yang digunakan dalam penelitian ini yaitu metode kuantitatif mengenai persepsi masyarakat dan analisis air sungai yang memberikan penjelasan tentang kondisi aktivitas stockpile pertambangan batubara dan pengaruhnya terhadap kualitas air. Melakukan kuesioner skala Likert dan pengambilan sampel air. Hasil penelitian menunjukkan bahwa terjadi perubahan sifat kimia air terhadap kondisi alami Sungai Pendreh. Perubahan sifat fisik-kimia air yang terpengaruh akibat kegiatan stockpile tambang yaitu pada parameter Total Suspended Solid (TSS), tingkat keasaman (pH) dan Mangan (Mn).
