Let G = (V(G),E(G)) be a graph with the nonempty vertex set V(G) and the edge set E(G). Let Zn be the group of integers modulo n and let k be a positive integer. A modular irregular labeling of a grap... see more

Indonesia has an abundant agricultural sector. The agricultural sector is very abundant, one of which is coconut oil, palm oil. Oil prices are often uncontrolled fluctuations that cannot be determined based on parameters. The ups and downs of oil prices c... see more

The purpose of the article is to detect crop production on agricultural enterprises clusters at a price by defining their amplitude of price fluctuations. Methodology. The study is based on grouping of statistical data from agricultural enterprises using ... see more

Let G and H be two given graphs. The notation F?(G,H) means that any red-blue coloring on the edges of F will create either a red subgraph G or a blue subgraph H in F. A graph F is a Ramsey (G,H)-minimal graph if F satisfies two conditions: (1) F?(G,H), a... see more

We use Rosa-type labelings to decompose complete graphs into unicyclic, disconnected, bipartite graphs on nine edges – namely, those featuring cyclic component C4, C6, or C8. For any such graph H, we prove there exists an H-design... see more

Let G = (V, E) be a simple undirected graph. A labeling f : V(G)?{1, …, k} is a local inclusive d-distance vertex irregular labeling of G if every adjacent vertices x, y ? V(G) have distinct weights, with the w... see more

In this paper, the vertex-degree function index Hf(G) is considered when function f(x) belongs to four classes of functions determined by the following properties: strictly convex versus strictly concave and strictly increasing versus ... see more

Let G be a connected, simple, and undirrected graph, where V (G) is the vertex set and E(G) is the edge set. Let k be a natural numbers. For graph G we define a total k-labeling ? such that the vertices of graph G are labeled with {0, 2, 4, . . . , 2kv} a... see more

ABSTRACT. The purpose of this study was to examine replacement rice bran (RB) with the mixture of Aloe vera flour (AVF) + sunflower seed flour (SFS) within the fermented feed of which with the addition of other feed ingredients used to replace 25% of the ... see more
