Abstract

This research aims to determine a prediction model using Simple Linear Regression for time series data on the number of elementary school students in Cilacap from 2010 to 2023 and to obtain predicted results on the number of elementary school students in Cilacap for the following year. The data pattern of the number of elementary school students in Cilacap is known to have a decreasing trend. The time series data was subjected to the Durbin-Watson test to see whether there was autocorrelation. It was found that data on the number of elementary school students in Cilacap from 2010 to 2023 did not have autocorrelation with the Durbin-Watson (d) computing value of 1.385. The requirements for time series data have been met, so that forecasting analysis can be carried out using Simple Linear Regression and it is found that the regression equation is y ̂=168698.604-1600.519x. This regression equation is used to predict the value of the number of elementary school students in Cilacap for the next year. The forecasting accuracy level is 97.303% or with a MAPE error value of 2.697%, which means that the ability of the regression model to predict is very accurate. Thus, the predicted data on the number of elementary school students in Cilacap for the next period in 2024 is 144690 students. Keywords: Forecasting, Time Series, Linear Regression

Abstract

The Project for Strengthening the Profile of Pancasila students is a new paradigm for the independent curriculum. In the Project for Strengthening the Pancasila Student Profile (P5), there are several dimensions that are important to pay attention to. These dimensions include aspects of character that must be considered in an effort to strengthen students' understanding and practice of Pancasila values. The first dimension of character is Faith and Piety, Independence, Collaboration, Global Diversity, Critical Reasoning and Creative. Character education should start from an early age. This research aims to determine the implementation of the Pancasila Student Profile Strengthening Project (P5) and the impact of its implementation on the six dimensions of student profile character in PAUD. The research method used is a qualitative case study type with data collection techniques using observation, interviews and documentation. The research results show that the implementation of P5 at the TPA Raodhatul Jannah has been carried out with the theme "I Love Indonesia". Each theme implemented goes through the stages of initiation, development and conclusion. In general, starting from planning, implementing and concluding the project went smoothly and had a positive impact on the three dimensions of the project to strengthen the profile of Pancasila students, namely global diversity, mutual cooperation and creativity. Thus, the project to strengthen the profile of Pancasila students can familiarize students with the dimensions of child character. from an early age and can be one solution in producing a generation of Indonesians with character.

Abstract

This study aims to describe students' errors in solving math problem solving based on Newman's theory. This research method is qualitative with a case study approach. The subjects of this study were 18 students of the Elementary School Teacher Education Study Program in the odd semester of the 2023/2024 academic year who took Mathematics courses. Data related to student errors according to Newman's theory were obtained from tests and interviews to identify the types of errors made by students, which included errors in reading, understanding, transformation, process skills, and writing the final answer. Subjects were taken using purposive sampling technique and data validation using method triangulation. Data analysis techniques used data reduction, data presentation, and conclusion drawing. The results of this study showed that the most student errors made were process errors as much as 32.97% with fairly high criteria followed by errors in writing the final answer as much as 29.67%, transformation errors as much as 27.47% which were included in the criteria quite high and the last error understanding the problem as much as 9.89% with very low criteria. Based on the results of the study, it is suggested that students should practice more independently working on problems, especially story problems. In addition, before working on the problem, students should first write down the complete information in the problem.
