“…A maximum surface area of 148.3 m 2 g -1 was achieved at an activation temperature of 800°C. It has also been shown that increasing the carbon-to-metal oxide ratio in the ash matrix as well as the activation temperature can increase the surface area, pore volume, and hence the adsorption capacity [8][9][10][11][12][13][14][15]. These efforts were not focused on optimizing the experimental conditions to improve the surface properties of AC.…”

“…Nilai konduktivitas karbon sekam padi tertinggi yaitu 6,04 S.m -1 pada suhu kalsinasi 900 o C. Nilai konduktivitas tersebut terletak pada daerah nilai konduktivitas listrik yang dimiliki oleh material semikonduktor yaitu terletak pada nilai 10 . Hasil ini jika dibandingkan dengan carbon black dari sekam padi hasil penelitian Wang et al (2011) …”
