Abstract
Proses solvothermal menggunakan senyawa asam sulfat (H2SO4) dilakukan untuk doping sulfur pada limbah masker medis menghasilkan material S-Doped Porous Carbon. S�Doped Porous Carbon merupakan bahan karbon berpori yang memiliki luas permukaan yang esar. S-Doped Porous Carbon dapat dikombinasikan dengan semikonduktor CuO menjadi komposit fotokatalis yang dimanfaatkan dalam proses degradasi limbah zat warna Methylene Blue. Tujuan penelitian ini adalah menganalisis pengaruh penambahan massa S-Doped Porous Carbon terhadap struktur dan morfologi komposit S-Doped Porous Carbon/CuO dan kemampuan komposit S-Doped Porous Carbon/CuO dalam mendegradasi limbah Methylene Blue. Metode penelitian ini adalah eksperimen, terdiri sintesis CuO, sintesis S-Doped Porous Carbon, dan sintesis komposit S-Doped Porous carbon/CuO dengan variasi penambahan massa S-Doped Porous Carbon 0,3g, 0,5g, 0,7g. Kemudian dilakukan pengujian karakterisasi material
meliputi uji XRD, FTIR, SEM/EDX, BET, spektrofotometri UV-Vis dan GC-MS. Berdasarkan pengujian karakterisasi XRD, FTIR, SEM/EDX menunjukkan bahwa komposit S-Doped Porous Carbon/CuO berhasil terbentuk. Selanjutnya pada hasil uji BET diperoleh nilai surface area S-Doped Porous Carbon teraktivasi yaitu sebesar 902.098 m2 /g. Pada hasil uji fotokatalisis dan spektrofotometri UV-Vis menunjukkan bahwa komposit S-Doped Porous Carbon/CuO dengan penambahan massa S-Doped Porous Carbon 0,7 gram memiliki tingkat efisiensi degradasi paling tinggi dengan waktu penyinaran selama 2 jam yaitu sebesar 80,9%. Selanjutnya pada hasil pengujian GCMS menunjukkan bahwa senyawa methylene blue hasil fotokatalisis merupakan senyawa organik yang tidak berbahaya dan beracun.

The solvothermal process using sulfuric acid (H2SO4) was carried out for sulfur doping in medical mask waste to produce S-Doped Porous Carbon. S-Doped Porous Carbon is a porous carbon material that has a large surface area. S-Doped Porous Carbon can be combined with the degradation of the CuO semiconductor into a composite photocatalyst which is utilized in the Methylene Blue wastewater process. The purpose of this study was to analyze the effect of adding mass of S-Doped Porous Carbon to the structure and morphology of the S-Doped Porous Carbon/CuO composite and the ability of the S-Doped Porous Carbon/CuO composite in degrading Methylene Blue waste. This research method is experimental, consisting of synthesis of CuO, synthesis of S-Doped Porous Carbon, and synthesis of S-Doped Porous Carbon/CuO with variations in the addition of mass of S-Doped Porous Carbon 0.3g, 0.5g, 0.7g. Then the material characterization tests were carried out including XRD, FTIR, SEM/EDX, BET, UV�Vis spectrophotometry and GC-MS tests. Based on the XRD, FTIR, SEM/EDX characterization tests, it was shown that the S-Doped Porous Carbon/CuO composite was successfully formed. Furthermore, the BET test results obtained the surface area value of activated S-Doped Porous Carbon, which is 902,098 m2/g. The results of photocatalysis and UV-Vis spectrophotometry showed that the S-Doped Porous Carbon/CuO composite with the addition of 0.7 grams of S-Doped Porous Carbon mass had the highest level of degradation efficiency with an irradiation time of 2 hours, which was 80.9%. Furthermore, the results of the GCMS test showed that the photocataly
