Abstract

The estimated rice sales at Perum Bulog Sub Divre Medan is crucial information in planning and managing rice supplies. In this study, we apply the Double Exponential Smoothing forecasting method to estimate rice sales at Perum Bulog Sub Divre Medan. This approach allows us to identify complex sales patterns and generate accurate forecasts to aid in informed decision making. We use historical rice sales data to train a forecasting model and evaluate its performance. Experimental results show that the Double Exponential Smoothing method can provide reliable estimates of rice sales, with a satisfactory level of accuracy. The implications of these findings are discussed in the context of inventory management and operational planning of Perum Bulog Sub Divre Medan.

Abstract

This study aims to analyze the impact of problem-based learning on student learning styles. The research approach used is experimental by adopting observation and questionnaire methods. Data was collected from students who engaged in problem-based learning and students who followed conventional learning approaches. Analysis was carried out to compare differences in student learning styles before and after implementing problem-based learning. The results showed that problem-based learning had a significant impact on changes in students' learning styles, with more students tending to adopt active, collaborative, and reflective learning styles.
