Sintesis Karbon Nanofiber Berbasis Serat Daun Nenas Sebagai Elektroda Karbon …
The purpose of this research is to synthesize carbon nanofiber from pineapple leaf fibers as supercapacitor carbon electrodes. The synthesis of carbon nanofiber was carried out using two steps, namely KOH concentration variations and a combination of pineapple leaf fibers with pineapple leaves. The first step was to vary KOH concentration of 0.3 M, 0.5 M, 0.7 M, and 0.9 M. The best KOH concentr…

Carbonization and integrated physical activation processes were offered as an alternative method of production of activated carbon electrodes with relatively short time, ie ± 10.5 hours. This process was started by heating of samples at room temperature up to temperature resistant of 352oC using N2 at a rate of increasing temperature of 1oC/min. This process was continued until a maximum carb…

. The increase in oil palm plantations area will increase the oil palm plantation crops. Besides the results in oil palm fresh fruit bunches, the oil palm also produces waste in the form of pulp stems, leaves and midrib. Results of waste in palm midrib are very much in keeping with the age of oil palm itself. Therefore, the growth of palm oil can be predicted by knowing the length of midrib cau…
