Judul: Pelabelan Super Edge Magic pada Graf Cycle dan Graf Wheel
Abstrak: This manuscript proves that cycle graph and wheel graph have a super edge magic labeling. Super edge magic labeling on a graph is labeling that has an edge magic labeling with a set of vertices were mapped in to {1,2,… ,𝑝} and a set of edges were mapped in to {𝑝+1,𝑝+2,… ,𝑝+𝑞}, in which 𝑝 is order and 𝑞 is size on the graph. There are one lemma and two theorems to be discussed. The lemma is used to prove the two theorems. The first theorem proves that cycle graph 𝐶𝑛 is super edge magic if and only if 𝑛 is odd. The second theorem proves that wheel graph 𝑊𝑛 of order 𝑛 is not super edge magic. Moreover 𝑊𝑛 is not edge magic if 𝑛≡0 mod
