Heavy metal wastes cause water pollution. One of them is very toxic arsenic heavy metal waste; thus, treating them before they are released freely into the waters is necessary. In this case, the manufacture of carbon nanofibers (CNF) from sugar palm fiber waste is an innovation that can produce adsorbents to remediate heavy metals, thereby increasing the use value of sugar palm fiber waste. Carbon nanofiber from palm fiber (Arenga pinnata) was modified with ZnO metal, with varying concentrations of 0.1%, 1%, and 10%, in 1 gram of carbon nanofiber. Carbon nanofibers were made by carbonizing sugar palm fibers at 300oC for two hours. Furthermore, wet impregnation was carried out with Zn(CH3COO)2.2H2O and ended with calcination at 250oC for an hour, resulting in black nanofiber powder. This research was conducted to determine the effect of ZnO concentration on the characteristics of the carbon nanofiber produced and its effectiveness in remediating heavy metal arsenic. The ZnO/carbon nanofiber adsorbent material was then characterized using FTIR, XRD, and SEM analyses. Determination of the absorption of ZnO/carbon nanofibers on heavy metal arsenic was also assessed employing AAS analysis.

“…Sehingga, semakin lama waktu penyinaran maka energi foton yang diserap fotokatalis semakin banyak. Hal ini menunjukkan persentase degradasi rhodamin B semakin tinggi, karena semakin lama waktu fotosonolisis, maka rhodamin B yang terdegradasi akan meningkat sehingga banyak radikal OH yang dihasilkan untuk mendegradasi Rhodamin B(11).…”

Degradation of rhodamin B with ZnO-Fe impetus utilizing photosonolysis strategy has been finished with some variety. The objectives of this examination is to know impact of variety radiation times, groupings of doping Fe, and portrayal some spectrophotometer. The absorbance of tests when debasement was recognized by an UV-Visible spectrophotometer. The yield showed greatest season of irradation to degradate rhodamin B at 150 minutes, with the most rate debasement at any point is 91,19%. The occasions will used to figure out which the best fixation doping to degradate rhodamin B. For the variety of impetus fixation was acquired at ZnO-Fe 20% with a debasement level of 23,10%. Examination ZnO doping Fe utilizing UV-DRS(Diffuse Reflectance Spectroscopy) got the greatest band hole esteem is 3,24 eV.

Active carbon/rGO based on natural materials as coconut shell has been assembled with a coin cell in shape of prototype supercapacitor. The physical feature of active carbon/rGO electrode were characterized by FTIR, and FESEM. The Electrochemical performance of supercapacitor in 1 M LiPF6 electrolyte solution with density current of 12 mA/g until 163 mA/g were analyzed by galvanostatic charge-discharge test. The result showed that active carbon/rGO had absorption peaks at wave numbers 1592.27 cm−1 and 1288.45 cm−1 which were functional groups as C = C and C-O. The morphology of activated carbon has been covered by the presence of rGO that determines the agglomeration of rGO around the pore of activated carbon so that it affects the performance of supercapacitors. Supercapacitor has a specific capacitance charging of 20.5 F/g, and discharging of 19 F/g in density current 12 mA/g.
