2025-04-22T08:19:35+00:00

Paloh Naga Agrotourism is a popular destination for domestic and foreign tourists. Data from the Village-Owned Enterprises (BUMDes) shows a decrease in the number of visits during the period 2021 to 2024. This study aims to apply a fuzzy matrix model with the CETD (Combined Effective Time Dependent Data) method in analyzing tourist motivation and identifying the most significant motivational factors based on age group. The analysis results show that intellectual factors are dominant in the 15-17 age group. Social factors have a strong influence on the 26-30 age group, at the age of 18-25 the influence of social factors decreases and continues to decline in the 36-60 age group. Competence factors have an influence at the age of 15-17 and lose their influence at the age of 18-30 years. The relaxation factor had a significant influence on the 15-17 age group, especially for the need to escape from daily activities, and for the 26-30 age group the relaxation factor was irrelevant. These insights provide valuable implications that tourism managers tailor to the needs of each age group. Future research could extend the analysis with other demographic variables or advanced quantitative approaches.

Understanding mathematical concepts is crucial to students' success in solving mathematical problems. Improving this understanding requires a contextual learning model that supports active student engagement. This study examines the Contextual Teaching and Learning (CTL) model, which emphasizes the connection between lesson material and real life, and Edpuzzle, which supports interactive learning through videos with embedded questions. This study aims to examine the differences in the effects of the CTL model with Edpuzzle assistance and the conventional model on students' ability to understand mathematical concepts, as well as to test whether the CTL model with Edpuzzle assistance yields better results than the conventional model. The study employed a quasi-experimental method with a nonequivalent control group design. The subjects were 83 seventh-grade students at MTs Walisongo Sugihwaras, divided into an experimental class (CTL assisted by Edpuzzle) and a control class (conventional). There were five meetings, and pre- and post-tests were administered. Data collection techniques included tests, observations, and documentation. The data analysis revealed that the post-test scores of the experimental class students (average 79.6) were higher than those of the control class students (average 55). The t-test at a 5% significance level yielded a value of t-calculated= 12.017 > t-table= 2.021. Since the post-test data were non-homogeneous, the test was conducted under the assumption of unequal variances. These results suggest that the CTL model, when assisted by Edpuzzle, improves students' ability to comprehend mathematical concepts. Compared to the conventional model. These findings suggest that using a digital, technology-based, contextual approach is a promising strategy for learning.
