Research on the adsorption of the N-Graphene from coconut shell has carried out. The purpose of this study was to determine the N-Graphene produced from coconut shell can be formed and to prepare an electrode in primary batteries. This study uses coconut shell charcoal to produce Graphene. N-Graphene is produced by the method of nitrogen dopant. XRD data indicate a change in the position of the diffraction peaks (Graphene with 2θ = 24.03o and 44.6o and N-Graphene 2θ= 26.11o), meaning that there is interaction with the nitrogen atoms of carbon. The presence of N atoms in the N-Graphene is shown by the data of the EDX, which is 0.49% of atoms, and at the peak of wave number 1396 cm-1 shows the interaction between C-N. Graphene by BET analysis results show the surface area of Graphene 1140.2 m2/g with pore volume and pore size is 0.06144 cc/g and 1.072 nm respectively. Determination of the energy gap by measuring the resistance R of semiconductor materials at various temperatures. The resistivity and conductivity affected by temperature, the higher the temperature, the smaller the resistivity whereas the greater conductivity. Graph ln σ versus 1/T is a linear curve with a slope for each b = 915.22, b = 1529, b = 2515.1 which is the value of Eg/(2kB) because it obtained Eg value of 0.15 eV, 0.26 eV , 0.43 eV. From the characterization showed that the results of N-Graphene coconut shell-based has generated.
