Abstract

This study aims to model the factors that affect the financial performance of Bank Muammalat, including Capital Adequacy Ratio (CAR), Earning Asset Quality (KAP), Operational Expenses to Operating Income (BOPO), and Financing to Deposit Ratio (FDR) to Return on Assets. (ROA) This research uses secondary data taken based on time series. The analysis technique in this study uses multiple linear regression using SPSS software version 20 and Microsoft Office Excel 2010. The results of this study indicate that partially the CAR and KAP partially do not have a significant effect on Return On. Assets, while Operational Expenses to BOPO and FDR partially have a significant effect on Return on Assets. Simultaneously, these four variables have a significant effect on Return on Assets at PT Bank Muamalat Indonesia. Based on the results of the Determination Coefficient test, the value of Adjusted R Square (R2) is 99.00%, this means that the amount of Return on Assets can be influenced and explained by the variables CAR, KAP, BOPO, and FDR, while the remaining 1% is explained by variables not examined in this study.

Abstract

This study aims to describe students' mathematics learning outcomes through online learning for the 2019/2020 academic year on the subject of flat-sided space geometry. This descriptive study was conducted at SMP Negeri 5 Paguyaman involving 28 students of class VIII as a sample selected using the purposive sampling technique. Data collection techniques in this study were tests in the form of multiple-choice questions and student response questionnaires. The results of the research that refer to the cognitive domain of the revised Bloom taxonomy by Anderson and Krathwohl show that the C1 cognitive domain is remembering, the ability of students to remember, recognize or know a concept of the material being asked in the questions given an average of 77.36% is in a good category. C2 cognitive domain is understanding; students' ability to understand the material on average 35.75% is in the poor category. C3 cognitive realm applies, on this indicator, students' ability to apply the formula to the questions given an average of 17.85% is in the poor category. C4 cognitive domain analyzes students' ability to analyze the average question is 39.70% who are in the poor category. With the average percentage of all cognitive domains, namely 45.71%, students' mathematics learning outcomes through online learning on the subject of flat-side space geometry is still in the low category, and learning using Facebook Messenger has not provided maximum results.

Abstract

This paper discusses the determinants of a k-tridiagonal Toeplitz matrix using row reduction and cofactor expansion methods. The analysis was carried out recursively from the general form of the determinant of the tridiagonal Toeplitz matrix, the determinant of the 2-tridiagonal Toeplitz matrix, and the determinant of the 3-tridiagonal Toeplitz matrix. In the end, the general form of the determinant of the k-tridiagonal Toeplitz matrix is obtained.

Abstract

The study s a qualitative descriptive approach, and his research type is the study of library studies. Researchers aim to project sub-sub materials through the mathematical mind mapping of major semester ix classes, researchers are trying to collect data by reading, studying understanding and analyzing books as well as research journals, accessing Internet sites, or documents related to mind mapping. Mind mapping is the most effective and efficient way to input, store and extract data from the brain or into the brain. It works according to the natural workings of our brain, thus optimizing all the human brain's potential and capacity. The manufacturing of the mind mapping process requires that a number of basic characteristics are attained. There is also the basic characteristic; Paper, colour, line, letter, keyword, key image, and structure. Thus basically the mind mapping process is based on the development of the mind mapping process, resulting in a mind mapping that can help teachers and students in the mathematical process during the difficult part of the semester, and can make learning more meaningful and enjoyable because the learning material is visible to the whole so that students can readily understand the material given.

Abstract

Suppose there is a simple, and finite graph G = (V, E). The coloring of vertices c is denoted by c: E(G) → {1,2, ..., k} with k is the number of rainbow colors on graph G. A graph is said to be rainbow connected if every pair of points x and y has a rainbow path. A path is said to be a rainbow if there are not two edges that have the same color in one path. The rainbow connected number of graph G denoted by rc(G) is the smallest positive integer-k which makes graph G has rainbow coloring. Furthermore, a graph is said to be connected to rainbow vertex if at each pair of vertices x and y there are not two vertices that have the same color in one path. The rainbow vertex connected to the number of graph G is denoted by rvc(G) is the smallest positive integer-k which makes graph G has rainbow coloring. This paper discusses rainbow vertex-connected numbers in the amalgamation of a diamond graph. A diamond graph with 2n points is denoted by an amalgamation of a diamond graph by adding the multiplication of the graph t at point v is denoted by Amal (Brn,v,t).

Abstract

This study aims to analyze the independent learning of students in mathematics through e-learning in class IX SMP Negeri 10 Gorontalo. This research is a descriptive research type, with a population of all class IX students of SMP Negeri 10 Gorontalo, totaling 101 students, consisting of 4 classes. The sample in the study was 20 people using a simple random sampling technique. The data obtained were obtained from student learning independence questionnaire sheets, as well as interviews with students related to students' learning independence in mathematics through e-learning. Based on the results of the research and discussion that the researcher has described in the previous chapter, that the learning independence of students in mathematics through e-learning is seen based on five indicators of learning independence divided into three categories namely high, medium and low categories. There are 4 high category students with an answer percentage of 20%. Second, there are 13 students belonging to the medium category with an answer percentage of 65%. Third, there are 3 students in the low category with an answer percentage of 15%. Of the three categories, in general, students only fulfill part of the indicators of learning independence measured in this study. So based on this, it can be concluded that the independent learning of students in mathematics through e-learning in class IX SMP Negeri 10 Gorontalo is still classified as moderate, so it needs to be improved.

Abstract

Scheduling workers is one of the problems faced by every company. The regulations set by the company, the availability of the number of workers, and the division of labor are the determining factors in the scheduling system. This worker scheduling problem can be modeled as an Integer Programming problem. Integer Programming is an optimization technique with linear objective functions, linear constraint functions, and integer variables. This paper discusses the formulation of worker scheduling problems in the form of Integer Programming with workers in companies engaged in the production of Crumb Rubber with the objective function of minimizing the number of workers employed. The next model is implemented using the help of LINGO 11.0 software. The implementation results show that the model is able to produce optimal employee schedules.
