dc.description.abstract | Limbah pertanian berupa kulit semangka merupakan salah satu sumber adsorben yang dapat digunakan pada adsorpsi zat warna. Limbah zat warna akan memberikan dampak negatif terhadap lingkungan, termasuk organisme di dalamnya. Dari berbagai zat warna yang digunakan dalam industri tekstil dan kimia, metil jingga menjadi salah satu pewarna azo anionik yang paling sering digunakan. Penelitian ini bertujuan menentukan kapasitas dan efisiensi adsorpsi metil jingga terbaik dan mempelajari kajian isoterm adsorpsi dari dari kulit semangka. Metode adsorpsi batch digunakan untuk mengamati proses adsorpsi metil jingga. Kadar air kulit semangka adalah 95,30%. Hasil spektrum FTIR menunjukkan adanya gugus fungsi O-H, C-H, C-C, C-O-C, dan N-H. Waktu adsorpsi terbaik diperoleh dengan kapasitas dan efisiensi adsorpsi berturut-turut 7,66 mg/g dan 76,65%, yang dihasilkan pada kondisi 15 menit, bobot adsorben 0,02 gram, dan konsentrasi metil jingga 5 ppm. Model isoterm adsorpsi metil jingga mengikuti isoterm Langmuir dengan nilai R2=0,5513. Hasil penelitian menunjukkan kulit semangka berpotensi sebagai adsorben alternatif untuk zat warna. | |
dc.description.abstract | Agricultural waste in the form of watermelon rinds is one source of adsorbent
that can be used for dye adsorption. Dye waste will have a negative impact on the
environment, including the organisms in it. Of the various dyes used in the textile
and chemical industries, methyl orange is one of the most frequently used anionic
azo dyes. This research aims to determine the best adsorption capacity and
efficiency of methyl orange and study the adsorption isotherm of watermelon rind.
Adsorption method batch used to observe the methyl orange adsorption process.
The water content of watermelon rind is 95.30%. The FTIR spectrum results show
the presence of O-H, C-H, C-C, C-O-C, and N-H functional groups. The best
adsorption time was obtained with adsorption capacity and efficiency of 7.66 mg/g
and 76.65% respectively, which was produced under conditions of 15 minutes,
adsorbent weight of 0.02 grams, and methyl orange concentration of 5 ppm. The
methyl orange adsorption isotherm model follows the Langmuir isotherm with an
R value2=0.5513. The research results show that watermelon peel has the potential
as an alternative adsorbent for dyes | |
