Abstract

This research aimed to describe the development process and results of the Construct 2 Android-based education math game on number pattern subjects to increase student's ICT literacy. This research employed the Research and Development method with a 4-D development model. The development model consisted of 4 stages: the Define stage, the Design stage, the Development stage, and the dissemination stage. Also, the researchers developed the Android-based application based on ICT literacy indicators. The application must be valid, practical, and effective. The results showed a correlation coefficient value of 0.87 and included in the valid category with very high interpretation. The level of practicality of the developed product was 83.96% based on a users' responses questionnaire. The effectiveness was determined based on the percentage of students' learning outcomes which was 83.33%. The increase in students' ICT literacy was determined based on the ICT literacy questionnaire and learning outcome tests' average N-Gain score. The average N-Gain value obtained was 0.75, with an average value for the ICT literacy questionnaire of 0.89 and the average value for the learning outcome test of 0.61. Based on these three criteria, it can be concluded that the Construct 2 android-based educational math game on the number pattern material can improve students' ICT literacy.

Abstract

Locating metric coloring is a variation of metric coloring in graphs that integrates vertex coloring with the uniqueness of metric representations. In this coloring, each vertex in a connected graph  is assigned a color such that the distance vectors to each color class are distinct for every pair of different vertices. Let  be a coloring function (not necessarily proper). The coloring ccc is called a locating metric coloring if, for any two distinct vertices , their distance vectors , so it is obtained represents the partition of vertices by color classes. Thus, for every vertex, the distance vector  are different. Vertices may share the same color, whether adjacent or not, as long as their metric representations are unique. The smallest number of colors required for such a coloring is called the locating metric chromatic number, denoted  T This study focuses on analyzing locating metric coloring for three specific graphs: the Cherry Blossom graph , the Sun Flower graph , and the Closed Dutch Windmill graph . These graphs were chosen due to the absence of prior research on their locating metric coloring properties. The research method combines pattern recognition and a deductive-axiomatic approach. The proof process begins by determining lower bounds, followed by the construction of upper bounds through coloring function analysis. The resulting locating metric chromatic numbers for each graph are then established.

Abstract

In the real life, electric energy has become an essential resource which is needed by men. The commonly used fossil-based fuel which needs very long time in forming can cause some researchers try to create new energy resource which exploits solar energy. Solar tower is one of the tools which has been established by researchers. Thus, there is volumetric receiver inside the solar tower which has function as heat exchanger. Mathematic model which is employed in this research focuses on the air flow on volumetric receiver by applying finite volume method. The design is built based on wind speed and temperature around the solar tower in order to know the effect of wind speed and the temperature around toward the temperature inside the volumetric receiver. Based on the simulation result using MATLAB software, it is found that of wind speed ; and has an average temperature value on the volumetric receiver , , and with relative error . On the other hand, the effects of temperature around are about , , and with relative error .

Abstract

Rainbow antimagic coloring is a combination of antimagic labeling and rainbow coloring. Antimagic labeling is labeling of each vertex of the graph with a different label, so that each the sum of the vertices in the graph has a different weight. Rainbow coloring is part of the rainbow-connected edge coloring, where each graph has a rainbow path. A rainbow path in a graph is formed if two vertices on the graph do not have the same color. If the given color on each edge is different, for example in the function it is colored with a weight , it is called rainbow antimagic coloring. Rainbow antimagic coloring has a condition that every two vertices on a graph cannot have the same rainbow path. The minimum number of colors from rainbow antimagic coloring is called the rainbow antimagic connection number, denoted by In this study, we analyze the rainbow antimagic connection number of snail graph , coconut root graph , fan stalk graph and lotus graph .

Abstract

This research focuses on the analysis of Resolving Efficient Dominating Set (REDS) and its application in solving Electronic Traffic Law Enforcement (ETLE) problems using the Spatial Temporal Graph Neural Network (STGNN). Resolving Efficient Dominating Set (REDS) is a concept in graph theory that studies a set of points in a graph that efficiently monitors other points. It involves ensuring that each point v ∈ V (G) - D is dominated by exactly one point in D, with no adjacent points in D, and the representation of point v ∈ V (G) concerning D is not the same, which is termed as a resolving efficient dominating set. In the context of Electronic Traffic Law Enforcement (ETLE), the analysis of REDS has a significant impact. The theorem resulting from the analysis of REDS enables the determination of the number of traffic violation sensors required. Furthermore, by taking simulation data from road points, violation forecasting can be performed. The accurate predictions from this forecasting can assist authorities in anticipating and addressing traffic violation issues more effectively.

Abstract

The rainbow connection was first introduced by Chartrand in 2006 and then in 2009 Krivelevich and Yuster first time introduced the rainbow vertex connection. Let graph be a connected graph. The rainbow vertex-connection is the assignment of color to the vertices of a graph , if every vertex on the graph is connected by a path graph that has interior vertices in different colors. The minimum number of colors from the rainbow vertex coloring in the graph is called rainbow vertex connection number which is denoted . The results of the research are the rainbow vertex connection number of bull graph, net graph, triangular ladder graph, and graph composition (Pn[P1]).
