“…Pita lebar yang terletak di rentang bilangan gelombang 300-3500 cm -1 menunjukkan regangan O−H, akan tetapi bergeser ke bilangan gelombang yang lebih tinggi. Hal ini dikarenakan adanya penguapam kandungan air (Erabee et al, 2017). Pita lebar pada 1411,95 cm -1 mengindikasikan adanya getaran C-C pada cincin aromatik.…”

Abstrak. Pengembangan sistem penyimpanan energi elektrokimia yang efektif dan efisien menjadi sangat penting pada era evolusi teknologi dan industri modern saat ini. Penelitian ini mengemukakan karbon aktif sebagai bahan dasar material elektroda untuk diaplikasikan pada piranti penyimpan energi, khsusunya superkapasitor melalui analisa densitas, X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) dan Cyclic Voltammetry (CV). Karbon aktif berbentuk monolit disiapkan dari ampas jus wortel melalui pendekatan pirolisis satu tahap terintegrasi dan aktivasi kimia KOH. Proses pirolisis satu tahap terintegrasi dilakukan melalui penggabungan karbonisasi dan aktivasi fisika dalam atmosfer gas N2/CO2. Berdasarkan analisis data, karbon aktif menunjukkan sifat amorf yang normal dan sifat porositas terkonfirmasi. Lebih lanjut, sifat elekrokimia dievaluasi menggunakan metode Cyclic Voltammetry (CV) pada sistem dua elektroda. Kapasitansi spesifik yang dihasilkan sebesar 155 F/g dalam elektrolit 1 M H2SO4 dengan energi spesifik dan daya spesifik adalah 21,52 Wh/kg dan 77,57 W/kg. Berdasarkan analisa ini maka ampas jus wortel terkonfirmasi berpotensi sebagai karbon aktif untuk elektroda yang diaplikasikan dalam piranti penyimpan energi superkapasitor.Abstract. The development of an effective and efficient electrochemical energy storage system is very important in today's era of technological evolution and the modern industry. This research suggests that activated carbon is the raw material for electrode materials to be applied to energy storage devices, especially supercapacitors through density analysis, X-ray diffraction (XRD), Fourier Transform Infrared (FTIR), and Cyclic Voltammetry (CV). Activated carbon in the monolith form derived from carrot juice waste was prepared through a one-stage integrated pyrolysis approach and chemical activation of KOH. An integrated one-stage pyrolysis process was carried out by combining carbonization and physical activation in an N2/CO2 gas atmosphere. Based on data analysis, activated carbon performed normal amorphous behavior with confirmed porosity features. Furthermore, the electrochemical properties were evaluated using the Cyclic Voltammetry (CV) method at the two-electrode system. The specific capacitance was found as high as 155 F/g in the 1 M H2SO4 aqueous electrolyte with specific energy and specific power as high as 21.52 Wh/kg and 77.57 W/kg, respectively. Based on this analysis, the carrot juice waste has been confirmed to have the potential as activated carbon for the electrodes applied in supercapacitor energy storage technology.Keywords: Carrot Juice Waste, Activated Carbon, Electrode Materials, Supercapacitor

“…In practice, coal and many agricultural biomass byproducts are commonly used as raw materials to produce commercial activated carbons. There are many studies relating to the preparation and characterization of activated carbons from agricultural wastes [16][17][18][19][20]. However, it has been perhaps only a few publications reporting on the preparation of effective activated carbon catalyst from coffee ground residues.…”

This study focuses on the production of acetaldehyde from ethanol by catalytic dehydrogenation using Co/C catalysts with different Co loading on the activated carbon derived from coffee ground residues. The simple impregnation was used to obtain the Co/C catalysts having Co loading of ca. 4 and 6 wt%. The catalysts were characterized using various techniques. The dehydrogenation of vaporized ethanol was conducted in order to measure the catalytic activity and product distribution at temperatures ranging from 250 to 400°C. Based on this study, it appeared that the Co/C catalyst having ca. 4 wt% of cobalt loading (4%Co/C) exhibited the highest ethanol conversion (54%) at 400 o C with the acetaldehyde yield of 50%. In addition, all catalysts behaved similar catalytic properties, where the ethanol conversion increased with increasing the reaction temperature having acetaldehyde as a major product. The high activity obtained from 4%Co/C and C catalysts can be remarkably attributed to the high acidity to basicity (~1.50). Hence, the 4%Co/C is promising catalyst for ethanol dehydrogenation to acetaldehyde.

“…due to its high degree of micro porosity, just one gram of activated carbon has a surface area in access of 500 m 2 , with 1500 m 2 being readily achievable as determined by adsorption of nitrogen gas [3]. Many previous studies investigated the using of different agricultural waste as a raw material to produce activated carbon, such as rice husk [4], jute and coconut fibre [5], coconut husk [6], sago palm bark [7], and modified activated carbon [8,9,10]. The activated carbon contractors generally consist of the activated carbon that will act as the filter bed inserted in the contractor, commonly fabricated from concrete or steel columns in rectangu-lar or cylindrical shape.…”

This study presents a water treatment process by using a down-flow fixed bed activated carbon contractor model. Two types of activated carbon (AC) used, powder and granular activated carbon from date pits as a raw material, the parameters tested are biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solid (TSS), total dissolved solid (TDS) and pH. The column diameter and bed depths are made constant, whereas the size of activated carbon is varies. The obtained removal efficiencies for sample of river water are 39.8% of BOD, 41.8% of COD, 81.8% of TSS and 67.7% of TDS for granular AC. For powdered AC the removal efficiencies of parameters are 34.7% of BOD, 17.6% of COD, 72.7% of TSS and 50% of TDS. The granular AC made from date pits is the best activated carbon because of low cost of raw material and it is widely applied for usage in the water or wastewater treatment, as it is very effective in terms of cost and performance to cater the increasing demand of clean water.
