Abstract

Given a graph , super graceful labeling is bijective function  such that  for every edge . A graph  that has a super graceful labeling called a super graceful graph. In this  final paper discuss about super graceful labeling for special graphs graph Pn , graph Pm(n) , graph Pn+-e1 , graph Cn n≥3 graph Pn1,2,…,n , graph Km,n , and graph Coconut tree

Abstract

In this paper is discussed an algebraic structure which is called RG-algebra. The RG-algebra is a subclass of BCI-algebra and a sub subclass of K-algebra. Therefore, everyRG-algebra is a BCI-algebra, but conversly is not true. The RG-algebra andGroup Structure have a relation. Its relation is RG-algebra can be constructed by acommutativegroup and conversly commutativegroup can be constructed by a RG-algebra. The RG-algebra is a K-algebra with commutativegroupas generator group.

Abstract

 ABSTRACT. Game theory is a branch of mathematics that used to make some decisions in the competitive situations with goal to have an optimal profit. Game theory of matrix payoffs with parameters triangular fuzzy number called matrix games with payoffs of triangular fuzzy numbers. Resolving game theory problem with triangular fuzzy numbers must be converted before hand in the from of matrix game with payoffs of triangular fuzzy numbers. In this paper, we explain that this two person zero sum game mixed strategy  linier programming method and Deng-Feng Li’s model in that matrix game. We also explain about how to applicating two person zero sum model to solve the marketing problem.Keywords: Game Theory, Zero Sum Game, Fuzzy Number, Linier Programming Method, Deng-Feng Li’s model

Abstract

Derivasi BCC -aljabar merupakan pemetaan dari BCC -aljabar ke dirinya sendiri dengan pemetaan tersebut harus memenuhi derivasi-r,l sekaligus derivasi-l,r . Sesuai dengan konsep dari derivasi BCC -aljabar maka setiap derivasi BCC -aljabar  bersifat reguler. Dengan menggunakan sifat-sifat pada derivasi BCC -aljabar dan sifat-sifat pada BCC -ideal akan dipelajari pula mengenai konsep d -invariant.

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

Abstract

 ABSTRAK. Economic Order Quantity inventory model is a model that is widely used as a decision making tool for inventory control. EOQ model is used to find the optimal order quantity to minimize total inventory costs. This undergraduated thesis is about  Economic Order Quantity inventory model for deteriorating items that affecting to quality and product sale value, the constant demand rate without shortages in inventory, with permissible delay in payments. There are three cases in this inventory model. First, when permissible delay of payments period is less than the replenishment cycle period. Second, when permissible delay of payments period is greater than the replenishment cycle period. And third, when permissible delay of payments period equal to the replenishment cycle period.  Kata Kunci: Inventory, Economic Order Quantity model, delay in payments, deteriorating items.

Abstract

Suatu d -aljabar merupakan perumuman dari BCK -aljabar. Di dalam d -aljabar terdapat jenis-jenis ideal yaitu d -ideal, d# -ideal, dan d* -ideal. Dengan memanfaatkan konsep BCK -ideal dapat dibentuk d -ideal, d# -ideal, dan d* -ideal. Kemudian dengan menerapkan konsep d* -ideal dapat dibentuk d -aljabar kuosien. Kata kunci: d -aljabar, BCK -aljabar, d -ideal, d# -ideal, d* -ideal dan d -subalgebra
