Abstract

The COVID-19 pandemic that occurred starting in early December 2019 had a major impact on the world of education. Therefore, it is necessary to develop a flipped classroom-based mathematical learning model. The purpose of this study was to find out the effect of flipped classroom-based mathematical learning model on students of the Mathematics Education study program on Multivariable Calculus courses. This research is a pseudo-experimental study. The subject of this study is a mathematics education student who is pursuing multivariable calculus courses that are directly involved in the learning model applied at West Kalimantan which is divided into two classes with each class consisting of 15 students. Experimental classes are given learning using Flipped Classroom-based learning models while control classes are given learning with online learning using google classroom. This research design uses a randomized control group posttest only design. Data analysis techniques also use Mann-Whitney nonparametric hypothesis tests. The results of the study that has been conducted show a significance value of 0.015 less than the significance level of 0.05 so it can be concluded that there is a real difference between the control learning model and the Flipped Classroom model or the flipped classroom learning model effective to improve student learning outcomes.

Abstract

Let G be a graph with a set of vertices V(G) and a set of edges E(G). The distance from vertex u to vertex v in G, denoted by d(u, v), is the length of the shortest path from vertex u to v. The eccentricity of vertex u in graph G is the maximum distance from vertex u to any other vertices in G, denoted by e(u). Vertex v is an eccentric vertex from u if d(u, v) = e(u). The eccentric digraph ED(G) of a graph G is a graph that has the same set of vertices as G, and there is an arc (directed edge) joining vertex u to v if v is an eccentric vertex from u. In this paper, we determine the eccentric digraph of a class of graph called the cocktail party graph and hypercube.

Abstract

SNMPTN merupakan salah satu jalur masuk perguruan tinggi negeri yang banyak diminati siswa karena hanya menggunakan parameter nilai raport, prestasi siswa, dan prestasi sekolah. Setiap jurusan mempunyai nilai diterima minimal yang berbeda-beda, besaran kuota yang ditetapkan LTMP 2019 minimal hanya 20% dari daya tampung program studi di setiap perguruan tinggi negeri. Besarnya minat siswa dan kecilnya jumlah kuota tidak sebanding sehingga menyebabkan persaingan diterima pada jalur ini semakin ketat. Namun, masih banyak siswa yang belum mempertimbangkan parameter tersebut saat mendaftar sehingga kemungkinan diterima pada jalur SNMPTN semakin kecil. Oleh karena itu diperlukan sebuah sistem yang dapat memprediksi kemungkinan diterimanya siswa pada jurusan SNMPTN berdasarkan atribut yang sudah ditentukan. Naïve Bayes diterapkan untuk mencari nilai probabilitas terbesar dalam setiap variabel yang ada. Variabel yang digunakan meliputi nilai rata-rata matematika, bahasa indonesia, dan bahasa inggris semester 1 sampai 5 serta prestasi siswa yang dilampirkan saat mendaftar dan prestasi sekolah. Hasilnya dengan naïve bayes mampu menghasilkan akurasi sebesar 83,3%.

Abstract

This research implements a fuzzy topsis based system for selecting the best employees at PT. Delta World Textil. One of the matters, especially in the management of Human Energy Resources (HR) is the selection of the best employees periodically, so that those who are elected will be given an award in the form of a bonus in order to motivate employees to improve their service and performance. The best and quality employees are the legacy of the industry that wants to make the industry grow rapidly. Several methods have been proposed for selecting the best employees. However, the method used is inaccurate because it only uses one method with few criteria. This study aims to select the best employees by looking at several criteria in the form of discipline, teamwork, attitudes, presence, skills, loyalty, tenure, and productivity for initial processing using fuzzy logic. Initial values are obtained in the form of membership function values which are used as input into the topsis method. The first stage of the topsis method is carried out in the normalized decision metric stage, the results of this stage are used to find a weighted normalized decision matrix according to the weight of the criteria for each criterion, the results of this stage are used to ensure positive ideal solving and negative perfect solutions after that the distance between the values is determined. each alternative with a positive perfect solution matrix and a negative perfect solution matrix. In the last session, the highest preference value was sought so that the best employees were obtained. The results show that the system established is very feasible in ensuring the best employees in performance evaluation. Keywords : Fuzzy Logic, Topsis, Best Employees, Decision Support System

Abstract:For example G (V, E) is a simple graph, a graph that do not contain of loops and parallel sides. Labeling of a graph is a mapping (function) that carries elements of a graph into positive or non-negative integers. Labeling power of irregular total point of a graph is a mapping f: VÈE ® {1, 2, 3, ..., k}which is called as labeling k total irregular point (vertex irregular total k-labeling) in G, if the weight of each different point at G is not the same, that is f(x) + ¹ f(u) + for each of the two points x and u that are different in G.Determination of exact value of irregular power of the total point is done by showing the value of lower limit and upper limit, both of them are proved to have equal value. The upper limit is decided by constructing a label, so that the largest label is obtained by minimum way. According to these two steps, a value for irregular power of the total point of a graph is obtained. In this paper, we will investigate irregular total labeling on barbell graph.Keywords:Point Irregular Total Labeling, Barbell.

Abstract

The covid-19 pandemic period like now requires to find an alternative learning that is effectively used. It drives a changing method of learning from face-to-face to online. One alternative in learning today is the use of smartphones or commonly referred to as mobile learning. This study aims to determine: 1) differences in student mathematics learning achievement with learning through mobile learning and google classroom, 2) interaction between learning through mobile learning and the ability to work together with students towards mathematics learning achievement, 3) differences in student mathematics learning achievement at the level of ability cooperate. The subjects of this study were students of the Mathematics Education Study Program STKIP Pamane Talino who took 68 Integral Calculus courses consisting of 2 classes. The research was conducted in 5 meetings. Each group was taught with the same material. The instruments in this study were test and questionnaire. The research method used was quasi experiment with 2x3 factorial design approach. The data analysis test used was the two-way ANAVA test with the analysis prerequisites in the form of a normality test and a homogeneity test. The results of data analysis show that the data are normally distributed and homogeneous. Thus, it can be concluded that: (1) learning with Mobile Learning media is more effective than learning with Google Classroom media, (2) the level of ability to work together high, medium and low gives different effects on student mathematics learning achievements and (3) students with all levels of ability to work with learning media Mobile Learning and Google Classroom provide equally good learning achievements.
