The graph used in this paper is a connected, bounded, and undirected graph G, is used which contains a set of vertex V(G) and a set of edge E(G). It is called the efficient dominating set of a graph if every point V in D or is adjacent to one vertex in D. For a set of solutions of G in an ordered set,...

A rainbow vertex antimagic coloring namely rainbow vertex coloring and antimagic labeling. For a bijective function f E ( G ) → ...

All graphs considered in this paper are simple, finite and connected graph. Let G(V, E) be a graph with the vertex set V and the edge set E, and let w be the edge weight of graph G. with | V ( G ...

For any graph G = ( V , E ) , the order and size of G are p and q. Let G(V, E) be a graph with the vertex set V and the edge set...

Previously we built a Max-Plus Algebraic model for the problem of the hierarchical structure of the Semi-Double Track railway line based on the Petri Net model. Then we also perform a delay simulation on the model obtained. Based on this research, we conclude that the Petri Net model does not reflect...

Let G(V(G), E(G)) be a connected, undirected, and simple graph with vertex set V(G) and edge set E(G). For a bijective function f : V ( G ) ⟶ ...

This study aims to develop rainbow antimagic coloring. A graph G is said to be a rainbow antimagic coloring if there is a bijection function f : V ( G ) → ...

Suppose G is a bounded, connected, and undirected graph. Let V(G) and E(G) be the vertex set and edge set, respectively. The subset D of V(G) is a subset of the graph G that dominates it efficiently if every vertex in G is either in D or adjacent to a vertex in D. The subset M of V(G) is the complete...

Literacy is an important skill in the 21st Century. The research aims to describe the ability of elementary school students with field dependent and field independent cognitive style in Mathematical literacy. Type of this research was qualitative research. The research subject was student of SDIT Ar-Risalah...

In this study, we explore the idea of rainbow antimagic coloring, which combines the notions of antimagic labeling with rainbow coloring. We consider a connected and simple graph G(V, E) with a vertex set V(G) and an edge set E(G). A vertex labeling of graph G is defined as a bijective function ...

A simple solution to solving the problem of alternating current circuit materials. Alternating current circuit material is a material that has many mathematical equations and depends on the type of circuit combination. The combination of circuits on alternating current material is RC, RL, LC, and RLC...

Electronic devices that are made from semiconductors have made a lot of progress in the size of basic components that are more practical and effective, meaning that the size is getting smaller with greater data storage. The progress of these electronic devices cannot be separated from the tunneling effect...

For any graph G = ( V , E ) , the vertex set V and the edge set E, and let w be the edge weight of graph G, with ...

We consider the following resource allocation problem on a directed acyclic graph (the precedence graph). Suppose we have a given X units of a resource that must be distributed among N activities with some of given return functions ri(x). The problem is to allocate all of the X units of resource to the...

Roads are often used to travel from one place to another. To shorten the trip, it is usually done via the shortest route. Choosing the shortest route cannot be separated from the risks that can occur, such as accidents. Risk management serves to minimize this from happening. Analysis of the feasibility...

Fertilizer is becoming a big subject among small farmers. Due to a lack of fertilizers, small-scale farmers have been obliged to purchase both subsidized and unsubsidized fertilizers. This issue has effects on farmers’ decisions to purchase fertilizers that are subsidized or not. This study intends to...

The price of cooking oil in Jember Regency, has continued to fluctuate over the past few months. These changes in cooking oil prices certainly have implications for the decline in people’s purchasing power and the producer’s selling power. Prices at the producer level must be properly transmitted to...

Biochar is a carbon-rich material that has various functions in improving soil properties. This research aimed to determine the characteristics of improvement in soil chemical properties and soybean plant growth by adding biochar from various biomass sources. The design used was a factorial complete...

This study aims to determine the effect of increasing the value of carbohydrate, protein, fat, and calories content in artificial feed added with fish oil and to find out the best composition of the addition of fish oil in artificial feed that provides optimal protein levels for the growth of laying...

Food security is a system consisting of three sub-systems, namely availability, distribution and consumption. The participation of horticultural farmers in efforts to support food security is needed to achieve food self-sufficiency. The purpose of the research is to analyze; (1) gender conditions and...

Rice products come from paddy cultivated by farmers. Farmers as upstream actors in rice agribusiness obtain lower exchange rates than paddy and rice traders. This condition reflects the low purchasing power of farmers from paddy farming for the products consumed (e.g., rice). This study aims to (1) determine...
