Abstract

Expert system is a system basic computerize which use knowledge, fact, and intellectual activity to solve problem as usually can be solve by an expert on that field. Application of fuzzy – Mamdani method on expert system purpose to explain expert knowledge on not absolute, not complete and so complicated field. One of expert system application is to detect heart coronary disease. Heart coronary disease is the first killer in Indonesia. The number of  patients is so many maked the role of medical personnel often have limitation in detecting heart coronary disease. In this final paper has been made expert system application program in detecting heart coronary disease by fuzzy – Mamdani. Risk factors that influence heart coronary disease are age, LDL, total cholesterol, HDL, triglycerides, sistolik blood pressure, and diastolik blood pressure. Based on that risk factors will be obtained output which is risk percentage a person who is infected heart coronary disease. Keywords : Expert system, fuzzy – Mamdany, heart coronary disease

Abstract

ABSTRACT.A Let G = (V, E) be a graph and bijection map f:V → {1,2,..| V |}. For every edge uv∈E assign the label 1 if either f(u)  divide out of f(v) or f(v)  divide out of f(u) and assign the label 0 otherwise. A mapping f is called divisor cordial labeling if the difference between the number of edges having labels 0 and the number of edges having labels 1 which is to equal or less one. A graph has a divisor cordial labeling is called divisor cordial graph. Some special classes of graphs such as full binary tree graph, G*K_(2,n) graph, G*K_(3,n) graph where n even, G=<K_(1,n)^((1)),K_(1,n)^((2))> graph, G=<K_(1,n)^((1)),K_(1,n)^((2)),K_(1,n)^((3))> graph and sun graph〖 C〗_(n ) (〖.K〗_1 ) ̅ are divisor cordial.Keywords :    divisor cordial labeling, full binary tree graph, G*K_(2,n) graph, G*K_(3,n) graph, G=<K_(1,n)^((1)),K_(1,n)^((2))> graph, G=<K_(1,n)^((1)),K_(1,n)^((2)),K_(1,n)^((3))> graph and sun graph

Abstract

ABSTRAK. Graf G dengan himpunan titik V(G) dan himpunan sisi E(G) dikatakan mempunyai pelabelan selisih kuadrat jika terdapat suatu fungsi bijektif f:V(G)→{0,1,2,…p-1}, dengan p adalah banyaknya titik sedemikian sehingga terdapat fungsi terinduksi f^*:E(G)→N dengan f^* (uv)=|[f〖(u)]〗^2-[f(v)]^2 | dimana setiap sisi mempunyai nilai pelabelan yang berlainan. Suatu graf G yang mempunyai pelabelan selisih kuadrat maka graf G dikatakan sebagai graf selisih kuadrat. Pada tugas akhir ini dikaji bahwa graf graf lengkap, graf sikel,  graf K_2+mK_1, graf nK_3, dan graf nC_5 merupakan graf selisih kuadrat. Kata kunci : Pelabelan selisih kuadrat, graf selisih kuadrat
