Abstract

This study aimed to investigate how activator hydrochloric acid (HCl) concentration affects the adsorption capacity of corncob-activated carbon in Methylene Blue (MB) dye.  This was followed by immersion in HCl solutions with various concentrations (2.5 M; 3M; 3.5 M; and 4 M) as chemical activating agents. Next, FTIR and XRD were used to characterize the activated carbon that had been activated and unactivated. The study analyzed the reduction of methylene blue dye concentration in the air to evaluate the effectiveness of activated carbon as an adsorbent. It examined various factors influencing the adsorption process, including different initial concentrations of the azo dye (20 ppm, 30 ppm, 40 ppm, 50 ppm, and 60 ppm) and contact times (15, 30, 45, and 60 minutes). The experimental results indicated that a 3 M concentration of HCl was the most effective activator, leading to a maximum dye removal rate of 80.77%. For an initial concentration of 20 ppm of the azo dye, the highest adsorption results were achieved at 85.67%. Furthermore, the optimal contact time for maximum adsorption was found to be 30 minutes, with a peak adsorption rate of 70.08%. The Langmuir adsorption isotherm model demonstrated a better fit for the adsorption of methylene blue onto corncob-activated carbon. It can be concluded that activated carbon produced from corn cobs and treated with HCl is an effective adsorbent for reducing methylene blue levels in the solution.

Abstract

Exploration of the chemical profile and antioxidant properties of ethanol extract derived from Ruellia napifera leaves is very important, considering the usefulness of these leaves for use in natural therapy products. This research investigates the identification of secondary metabolite compounds and the antioxidant activity of ethanol extract from Ruellia napifera leaves. The objectives are to determine the types of secondary metabolite compounds present and to evaluate the antioxidant potential using the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging method. Ethanol extracts were prepared using the maceration method at durations of 24 hours. Phytochemical tests revealed the presence of flavonoids, alkaloids, saponins, and steroids. Antioxidant activity was measured through IC50 values, indicating the extract’s ability to inhibit 50% of the DPPH radicals. The IC50 values obtained were 10.66 μg/mL. For comparison, vitamin C as a positive control exhibited an IC50 of 2.49 μg/mL. These results suggest that the Gempur Batu leaf extract has strong antioxidant potential. These findings suggest that this extract from Ruellia napifera leaves holds potential for developing natural antioxidant-based therapeutic products or herbal medicine formulations.

Abstract

Penambahan aktivator kimia dimaksudkan untuk meningkatkan luas permukaan karbon dan membuka pori-pori yang tertutup, sehingga meningkatkan kapasitas adsorpsi karbon aktif. Penelitian yang menggunakan tiga aktivator kimia yang berbeda - HCl, NaOH, dan Na?CO? - bersama dengan aktivasi fisik pada suhu 750°C menunjukkan peningkatan kualitas dibandingkan dengan proses tanpa aktivasi. Ketika memproduksi karbon aktif dari tebon jagung, hasil yang tinggi sebesar 80-82% dapat dicapai. Uji evaluasi terhadap karbon aktif menunjukkan parameter berikut: kadar air berkisar antara 6% hingga 8,79%, kadar abu antara 2,89% hingga 4,49%, dan bilangan iodin bervariasi dari 751,11 hingga 812,16. Hasil ini memenuhi standar yang ditetapkan oleh SNI 06-3730-1995. Temuan ini mengindikasikan bahwa HCl merupakan aktivator kimia yang paling efektif untuk mensintesis karbon aktif dari tongkol jagung. Kesimpulan ini didukung oleh karakterisasi FTIR dan XRD. Analisis FTIR menunjukkan adanya gugus fungsi yang khas dari arang aktif, seperti O-H, C=O, dan C-C. Selain itu, analisis XRD menunjukkan adanya SiO? amorf, yang merupakan sifat yang menguntungkan untuk adsorben yang terdefinisi dengan baik, yang diamati pada sudut 2? 20-30 derajat.   The addition of chemical activators is intended to increase the surface area of carbon and open closed pores, thereby enhancing the adsorption capacity of activated carbon. Research utilizing three different chemical activators—HCl, NaOH, and Na?CO?—along with physical activation at 750 °C demonstrated improved quality compared to processes without activation. When producing activated carbon from corn stover, a high yield of 80-82% was achieved. Evaluation tests on the activated carbon revealed the following parameters: the moisture content ranged from 6% to 8.79%, the ash content was between 2.89% and 4.49%, and the iodine number varied from 751.11 to 812.16. These results meet the standards set by SNI 06-3730-1995. The findings indicated that HCl is the most effective chemical activator for synthesizing activated carbon from corn cob. This conclusion is further supported by FTIR and XRD characterization. FTIR analysis revealed the presence of functional groups typical of activated charcoal, such as O-H, C=O, and C-C. Additionally, XRD analysis revealed the presence of amorphous SiO?, a favorable property for a well-defined adsorbent, observed at 2? angles of 20-30 degrees.
