Water hyacinth has been used as a precursor for activated charcoal with H3PO4, KOH and ZnCl2 activators. After the activation process, the activated charcoal samples were treated without calcination and calcination at a temperature of 800 oC for one hour in an Ar gas atmosphere. Each sample of activated charcoal was characterized by N2 absorption at 77 K to determine the specific surface area, specific total pore volume and pore radius formed. From the test results, it was found that the calcination had a very significant effect on the properties of activated charcoal. Calcination of activated charcoal with KOH activator has the greatest effect on the properties of activated charcoal compared to other activators. Activated charcoal with KOH activator which was calcined had a specific surface area of 365.62 m2/g, a specific total pore volume of 0.42 cm3/g and a pore radius of 2.28 nm

“…Salah satu faktor yang mempengaruhi tingkat keefektifan superkapasitor adalah penggunaan bahan elektroda. Karbon aktif adalah salah satu jenis bahan yang secara luas telah digunakan sebagai bahan elektroda untuk superkapasitor karena memiliki luas permukaan spesifik yang tinggi, ketahanan kimia, konduktivitas listrik yang baik dan harga yang terjangkau (Babel dan Jurewicz 2004;Fellman 2010;Aripin et al 2010). Bambu dapat dijadikan sumber bahan baku dalam pembuatan karbon aktif.…”

“…Ketika dibandingkan dengan kontrol (arang tanpa perlakuan penambahan KOH dan steam) didapatkan bahwa arang yang telah diaktivasi dengan KOH dan steam 25 mL/bar, menunjukkan nilai daya jerap iodin yang cenderung lebih besar. Hal ini disebabkan dengan meningkatnya rasio penambahan KOH dapat menyebabkan peningkatan porositas (Aripin et al 2010;Babel dan Jurewicz 2004 ;Kierzek et al 2004).…”

PEMANFAATAN KARBON AKTIF DARI BAMBU SEBAGAI ELEKTRODA SUPERKAPASITOR ABSTRAKPada penelitian ini, karbon aktif berbasis bambu telah digunakan untuk pembuatan superkapasitor. Uji daya jerap iodin dilakukan untuk mengukur tingkat serapan pori sampel karbon aktif yang ukurannya relatif kecil (mikropori). Karakteristik bahan karbon aktif yang meliputi struktur kristal dan morfologi permukaannya diuji dengan menggunakan SEM dan XRD. Bahan elektroda dengan komposisi (Karbon aktif : PVDF = 9:1 (b/b)), kolektor arus dan separator telah dirangkai untuk diuji kinerjanya sebagai perangkat penyimpanan muatan listrik. Metode siklik voltametri digunakan untuk melihat kinerja perangkat superkapasitor dengan mengukur nilai kapasitansi spesifik berdasarkan kurva voltammogram. Berdasarkan hasil perhitungan nilai kapasitansi spesifik diperoleh nilai kapasitansi spesifik tertinggi pada superkapasitor dengan elektroda bambu yang diaktivasi dengan steam 50 mL/bar yaitu sebesar 59.50 F.Kata kunci: Karbon aktif bambu, siklik voltametri, kapasitansi spesifik, superkapasitor. UTILIZATION OF BAMBOO BASED ACTIVATED CARBON AS SUPERCAPACITOR ELECTRODE ABSTRACT In this study, bamboo based activated carbon has been used for fabrication of supercapacitors. Iodine absorption test is performed to measured absorption level porous activated carbon sample size is relatively small (microporous). Characteristics of the activated carbon material covering the surface morphology and structure were tested using SEM and XRD. Electrode materials with composition (Activated charcoal: PVDF = 9: 1 (w / w)), the current collector and separator has been assembled to be tested its performance as an electrical charge storage device. The test results by cyclic voltammetry method was to look at the performance supercapacitor devices at once to obtain the value of the capacitance curve obtained voltammograms. Based on the results of the calculation of the capacitance, the highest capacitance values obtained in the supercapacitor with activated carbon electrodes in bamboo steam 50 mL / bar with a capacitance value is 59.50 F / g.Keywords: Bamboo activated carbon, cyclic voltammetry, the specific capacitance, supercapacitor.

“…A typical device in which they are used is the electric double-layer capacitor (EDLC) [1]. In particular, the demand for EDLCs is growing rapidly because they are unique electrical storage devices that can provide a large amount of energy in a short time, have a high power density, and have a long cycle life as compared to that of conventional batteries [2].…”

A novel flat, wood-based carbon material with heterogeneous pores, referred to as flat lignocellulosic carbon material (FLCM), was successfully fabricated by carbonizing samples of the softwood Picea jezoensis (Ezomatsu or Jezo spruce, a Japanese conifer). Simultaneous improvements of the specific surface area of the FLCM and the affinity of electric double-layer capacitor (EDLC) for electrolyte solvents were achieved by vacuum ultraviolet/ozone (VUV/O 3 ) treatment. The specific surface area of the VUV/O 3 -treated FLCM showed a 50% increase over that of the original FLCM. The spectra measured by X-ray photoelectron spectroscopy (XPS) indicated that the number of O-C=O (carboxyl or ester) bonds increased, whereas the number of C-C bonds decreased. Additionally, the feasibility of using the FLCM as a self-supporting electrode in EDLCs was examined by measuring the electrochemical properties in a threeelectrode system. The FLCM was confirmed as an appropriate self-supporting EDLC electrode material without warps and cracks. In addition, the FLCM can be used without any binder. Realization of FLCM-based EDLC electrodes with bendability, an area of several tens of square centimeters, and no risk of warp or crack formation, were indicated. Thus, FLCMs present a fascinating class of self-supporting carbon electrode materials for EDLCs.
