																		When someone enters old age, symptoms such as senility or difficulty remembering new information often appear. This condition is known as dementia, a syndrome characterized by decreased cognitive function, behavioral changes, memory impairment, disorientation, and difficulty communicating and making decisions. This community service program aims to provide information and understanding about how to handle dementia that can be done at home. Activities are carried out through a counseling method consisting of a pre-test, education, and post-test, using leaflets and questionnaires containing questions to measure the level of understanding of participants. The results of the counseling showed an increase in participant knowledge, as seen from the comparison of the graph between the pre-test and post-test results. Education accompanied by brain gymnastics practices has been shown to have a positive impact on increasing participants' understanding of dementia and how to handle it. It is hoped that this counseling will continue to provide benefits to participants and can be applied in everyday life.

																		This study aims to analyze the implementation of project-based learning through the creation of clipping envelope(KLIPOP) of norms in the Pancasila Education subject, as well as to evaluate its impact on improving the learning outcomes of fifth-grade students at SDN Kutorejo 1 Tuban. The background of this research is the low student achievement in Pancasila Education, often caused by conventional, theoretical teaching methods that lack connection to students’ real-life experiences. The research method used is Classroom Action Research (CAR) with a descriptive quantitative approach. Data were collected through observation, interviews, documentation, and the results of pre-tests and post-tests. The findings show that project-based learning is effective in improving students’ learning outcomes. This is evidenced by the increase in the average test score from 74.8 (pre-test) to 91.3 (post-test). Students also demonstrated greater engagement, creativity, and collaboration in understanding the norms contained in Pancasila. By involving students in contextual activities, such as collecting information and creatively designing norm envelopes, learning becomes more meaningful and applicable. Therefore, this learning model can serve as a strategic alternative to enhance students’ understanding and academic performance in Pancasila Education at the elementary level.

																		Abstrak:
																		Air quality in Western Java is highly dynamic and shaped by environmental changes influenced by intense human activities. Aerosols—tiny particulate matter that affects air quality, weather, and climate—can be quantified using Aerosol Optical Depth (AOD), which measures aerosol concentrations in the atmospheric column. This research uses spatial regression analysis to examine the spatial distribution of AOD from GEE’s platform (Google Earth Engine) and its relationship with rainfall and wind patterns during both the wet and dry seasons. The findings indicate that wind speed does not significantly impact AOD values, but wind direction does affect the distribution of rainfall and AOD, likely due to the monsoon system. During the wet season (December to March), high-intensity and widespread rainfall effectively cleanses the atmosphere of aerosols, leading to no significant effect on AOD (p-value > 0.05). In contrast, during the dry season, rainfall significantly influences AOD spatial patterns (p-value < 0.05). These results highlight the intricate interplay between meteorological factors and aerosol’s behavior, emphasizing the seasonal variability in their interactions.

																		This research seeks to examine the effect of service quality on revisit intention, with customer satisfaction acting as a mediating variable, at Adiksi Coffee in Bandar Lampung. The study employed a survey method using questionnaires, gathering responses from 160 individuals who had previously visited Adiksi Coffee. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to assess the relationships among service quality, customer satisfaction, and revisit intention. The analysis utilized the SERVQUAL dimensions for measuring service quality, alongside performance, expenses and overall expectation dimensions for customer satisfaction, and the Theory of Planned Behavior (TPB) dimensions for revisit intention. The findings revealed that service quality significantly and positively influences customer satisfaction; service quality also directly and positively impacts revisit intention. Additionally, customer satisfaction was found to have a significant positive effect on revisit intention and served as a mediator in the relationship between service quality and revisit intention. This study highlights the critical role of service quality in shaping customer satisfaction and revisit intention within the coffee shop sector, particularly at Adiksi Coffee. These insights offer valuable practical implications for coffee shop operators aiming to enhance customer satisfaction and encourage repeat visits by focusing on service quality improvements.
