Abstract

Numeracy is a person's ability to implement mathematics in the home, work and community environments. This research aims to measure the practicality and effectiveness of using E-LKPD in a socio-cultural context assisted by GeoGebra workbooks in improving students' numeracy skills in pyramid material. The type of research used was a quasi-experiment (Quasi-experiment) with research subjects 21 class VIII students at SMPN 1 Kalisat Jember. The practicality of E-LKPD is assessed from the results of student response questionnaires, while the effectiveness of E-LKPD is assessed from the results of students' numeracy ability tests. The use of E-LKPD is said to be practical if the average percentage of students' questionnaire responses is at least in the practical category, and effective if students' numeracy skills are at least in the medium category. Based on the practicality analysis, the results of the student response questionnaire regarding the use of E-LKPD obtained a percentage of 81.67% or were in the practical category. In addition, the use of E-LKPD shows an increase in students' numeracy skills on all numeracy indicators. This can be seen based on the results of the numeracy ability test which obtained an N-Gain score of 0.51 or at a medium effectiveness level. Therefore, the use of E-LKPD in a socio-cultural context with the help of GeoGebra workbooks is practical and effective for improving students' numeracy skills, especially in learning surface area and volume of pyramids.

Abstract

A graph is defined as an ordered set (V,E) where V is a non-empty set of elements called vertices and E is a set of edges which are finite and may be empty and each edge connects two different points of V(G).The r-dynamic coloring is defined as c:V(G)→{1,2,3,…,k} such that it satisfies the following conditions if uv∈V(G), then c(u)≠ c(v), and ∀v∈V(G), |c(N(v))|≥min⁡{r,d(v)}, for positive integers r and degree of vertex v. The purpose of r-dynamic coloring is to find the minimum chromatic number of graph coloring with unlimited parameter r. Dynamic coloring is performed on cricket graphs because no research has been done before. The method used in this research is the axiomatic deductive research method and the pattern detection method.

Abstract

One of the topics studied in graphs is graph coloring. The definition of a graceful coloring, namely $k$-elegant coloring of a graph G is the exact vertex coloring c:V(G)→{ 1,2,...,k} where k≥2 induces the exact vertex coloring c^': V(G)→ {1,2,...,k-1} which is defined by c(uv)=|c(u)-c(v)|. The exact vertex coloring c of a graph G is a graceful coloring if c is a k-elegant coloring for k∈N. The graceful chromatic number is the minimum k value where graph G has k-elegant coloring, the elegant chromatic number of graph G is denoted by X_g (G). This article will discuss graceful chromatic numbers in the centripetal graph family which includes octopus graph (O_n), sandat graph (St_n),dutch windmill graph (D_3^m) , and a volcano graph (V_n).

Abstract

The study aims to analyze the airflow in the trachea due to thyroid cancer. Thyroid cancer is a cancer that attacks the thyroid gland. The thyroid gland is located in the neck below the Adam's apple. In general, thyroid cancer causes stenosis of the trachea due to cancer compression of the tracheal wall. This problem is solved using the finite volume method with SIMPLE (Semi Implicit Method for Pressure Linked Equation) discretization. This method is well suited for the discretization of irregularly shaped fluid flows. The software used is Matlab and Ansys Fluent. Matlab is used to compute numerical solutions and display graphs, while Fluent is used to visualize the air flow. The result of this study is that the greater the percentage of stenosis, the velocity of the airflow is faster and the pressure of the airflow is lower. The most critical condition for respiratory power loss is when the airflow velocity exceeds the normal limit, i.e. when the narrowing is more than 50%, the initial velocity is more than 0,1 m/s.
