African leaves (Vernonia amygdalina Del) is a plant that can be used as a medicinal plant because it contains flavonoid compounds that are effective as natural antioxidants that can suppress free radicals. The purpose of this study was to determine the antioxidant activity of the purified extract of Vernonia amygdalina Del. Antioxidant activity test of purified extract of Vernonia amygdalina Del leaves against 1,1-diphenyl-2-picrylhydrazil (DPPH) was measured with a UV-Vis spectrophotometer at a wavelength of 516nm using Vitamin C as a comparison. The results of the non-specific parameters of Vernonia amygdalina Del leaf Simplicia were drying shrinkage of 0.79±0.02%; water content of 7.33±2.08%; water-soluble essence content of 20.5±1.73 %; and ethanol of 14.5±4.35 %. The results of purified extract screening of Vernonia amygdalina Del leaves, contained chemical compounds, namely the class of flavonoid compounds, tannin compounds, steroid compounds, and saponin compounds. Testing for flavonoids using the Thin Layer Chromatography method on the purified extract contained two spots with Rf values of 0.68 and 0.5 while in quercetin there was one spot with an Rf value of 0.68, thus the purified extract of Vernonia amygdalina Del leaves contained flavonoids. Vernonia amygdalina Del leaf purified extract has a very strong antioxidant activity with an IC50 value of 13.54±0.10 µg/mL. The results showed that the purified extract of Vernonia amygdalina Del leaves had very strong antioxidant activity.
Salah satu tujuan SDG’s keenam adalah pada tahun 2030 mewujudkan 100 persen akses universal dan merata kepada air minum aman dan sanitasi yang terjangkau bagi semua. Secara umum, definisi ketahanan telah ada dan dirumuskan oleh UN-Water (2013), dimana ada enam aspek yang terkandung didalamnya. Belum ada suatu ukuran di Indonesia mengenai ketahanan air rumah tangga. Untuk mengetahui dan menggambarkan kondisi ketahanan air rumah tangga di Indonesia diperlukan indeks yang sampai saat ini belum tersedia yaitu Indeks Ketahanan Air Rumah Tangga (IKART) dengan mengacu kepada definisi ketahanan air UN-Water. Metode pembentukan indeks yang digunakan mengacu pada metode yang dikembangkan oleh OECD (2008) dengan menggunakan analisis faktor. Hasil yang diperoleh dari analisis faktor terbentuk dua faktor, yaitu faktor sarana air dan faktor sosial-ekonomi. Secara keseluruhan IKART yang dimiliki Indonesia sebesar 58,20 dan berada pada tingkatan cukup terpenuhi kebutuhan air rumah tangga. Papua menjadi provinsi dengan IKART terendah yaitu sebesar 9,56, sedangkan provinsi dengan IKART tertinggi adalah DKI Jakarta sebesar 83,82.
