Abstract

This research aims to describe the thinking process of students in creating concept maps based on visual, auditory and kinesthetic learning styles.This research is descriptive research with qualitative approach. The subjects consisted of 3 students based on the learning style questionnaire analysis. Data collection techniques are job-based interviews.The results showed that there are differences in students' thinking processes in creating concept maps. The three subjects perform the stage of creating a concept map completely but there are differences on how to make it. This happens because subjects with an auditory learning style can’t make a cross link so the resulting concept maps are different.The results of this research can be used as an alternative in developing learning by concept map method.

Abstract

The fixed point principle is very important in solving linear equation, ordinary differential equation, partial differential equation, and integral equation. The famous fixed point theorem is Banach's fixed point theorem. Kannan's fixed point theorem is generalisation of Banach's fixed point theorem. This article discusses some theorems that generalisations from Kannan's fixed point theorem with continuity mapping. Some theorems are discussed in this article guarantee the existence and uniqueness of a fixed point.

Abstract

The purpose of this study was to determine the maximum profit in Islah Convection. This study used the Kuhn-tucker method. The Kuhn-tucker method is a method used to determine the optimum value of a function with an inequality constraint. The steps of this research are forming decision variables, forming objective functions, forming constraint functions, forming mathematical models with linear programming, solving optimization problems using the Kuhn-tucker method, and drawing conclusions. The results of the completion of this study obtained a maximum profit of Rp. 273,562,325 in the production of 4 types of clothes, which include 200 units of male school uniform, 200 units of female school uniform, 60 units of alma mater coat, and 30 units of katelpak. . Based on the results of the optimization, it can be concluded that the profit of clothing production in Islah Convection is optimal

Abstract

Wavelet topics can be applied for image denoising. Wavelet transform is divided into discrete wavelet transform and continuous wavelet transform. Discrete wavelet transform is useful for image denoising, image compression, etc. In this research, we discuss image denoising using wavelets with hard thresholding and soft thresholding. We will also compare results of image denoising using VisuShrink, BayesShrink, and NormalShrink in determining threshold value. In this research, we use grayscale test image with size pixels. To measure algorithm, peak signal to noise ratio (PSNR) value is used. Image denoising uses hard thresholding: PSNR values of Haar, Daubechies 7, and biorthogonal 3.5 wavelets are same for three methods (VisuShrink, BayesShrink, NormalShrink). PSNR value of symlets 11 wavelet is highest for VisuShrink and NormalShrink methods. Whereas, PSNR value of coiflets 3 wavelet is highest for VisuShrink method. Fastest computing times of Haar, Daubechies 7, biorthogonal 3.5, and symlets 11 wavelets are for VisuShrink method. Whereas, fastest computing time of coiflets 3 wavelet is for NormalShrink method. Image denoising using soft threshoding: PSNR values of Haar, Daubechies 7, biorthogonal 3.5, and coiflets 3 wavelets are same for three methods (VisuShrink, BayesShrink, NormalShrink). Whereas, PSNR value of symlets 11 wavelet is highest for VisuShrink and BayesShrink methods. Fastest computing times of all wavelets (Haar, Daubechies 7, biorthogonal 3.5, symlets 11, and coiflets 3) are for NormalShrink method.

Abstract

This research gives more explaination in proof of theorem. The theorem is about existence and uniqueness a point is called fixed point in an extended b-metric space. Beside that, also we give example about extended b-metric space.

Abstract

Forecasting is a method in statistics that aims to estimate or predict a condition in the future. The results of forecasting can be used as a reference or indicator in predicting conditions at the next time. This research was carried out by predicting the unemployment rate in the city of Lamongan for the next period, using the Brown double exponential smoothing method based on data from 2001 to 2023. The forecasting accuracy method used in forecasting unemployment is Mean Absolute Percentage Error (MAPE) for calculate the percentage error for each ? parameter value. From the research results, the best ? parameter value was obtained for forecasting the unemployment rate in the city of Lamongan in the future by obtaining the smallest MAPE value chosen by trial and error.
