Abstract

In March 2023, the percentage of poor people in urban areas was 8.23% and in rural areas was 8.03%, with a decrease of 0.40 points in urban areas and an increase of 0.07 points in rural areas compared to September 2022. Based on these facts, it can be concluded that there has not been even development between villages and city. Cluster analysis is a tool that can be used to group cities and regencies in North Sumatra Province. This research analyzes the comparison of the K-Means, K-Medoids and Fuzzy C-Means methods in conducting cluster analysis. Where in the K-Means method, cluster 1 has 4 cities/regencies, cluster 2 has 8 cities/regencies and cluster 3 has 21 cities/regencies. In the K-Medoids method, the cluster results are the same as the cluster results of the K-Means method. Meanwhile, in the Fuzzy C-Means method, Cluster 1 has 9 cities/regencies, cluster 2 has 16 cities/regencies and cluster 3 has 8 cities/regencies. Then, based on the Davies Bouldin Index (DBI) values from the three methods, it was concluded that the cluster results of the K-Means method were more optimal compared to the K-Medoids and Fuzzy C-Means methods because they had the smallest DBI value.

Abstract

Population growth is the rate of change in the number of people living in an area at a given time compared to the number of people living in that area previously. Population changes have significant implications as they can influence the progress and welfare of a region. Population growth is one of the important factors that influence the social, economic, and environmental dynamics of a region. The prediction of population growth in Karo Regency aims to understand demographic dynamics and its implications for regional development. Karo Regency, located in North Sumatra, Indonesia, is experiencing a significant increase in population due to factors such as migration, births, and deaths. Based on data obtained from the Central Bureau of Statistics (BPS) of Karo Regency in 2020-2023, it can be assumed that the capacity (K) = 500,000. One alternative that can be used to forecast the population in Karo Regency is to utilize the logistic growth model. The results showed that the logistic model I with a relative growth rate per year of 7.26% so the results show that the population prediction of Karo Regency in 2025 is 425,385 and 2026 is 434,148.

Abstract

This study aims to examine the effectiveness of the Problem-Based Learning (PBL) model integrated with teacher feedback in improving students’ understanding of the topic of trigonometry in right triangles. Due to students’ difficulties in comprehending the abstract nature of right triangle trigonometry and memorizing formulas, an innovative learning model is required to facilitate their understanding. This model also provides opportunities for students to practice problem-solving skills in real-life contexts, fostering critical thinking abilities.The results indicate that the PBL model, combined with teacher feedback during the learning process, produced better outcomes, as evidenced by cognitive test measurements. The experimental method used in this study was a one-group pre-test post-test design conducted quantitatively. Data were collected from a population of Grade X students at a high school in Serang City. The study employed test instruments consisting of multiple-choice and essay questions for data collection, which were analyzed using the non parametric paired sample t-test method.The analysis showed a significant improvement in the average scores, with post-test scores being higher than pre-test scores. It can be concluded that the implementation of the Problem-Based Learning model, integrated with teacher feedback, effectively enhances students’ understanding of the topic.
