Climate change has had a significant impact on various aspects of life, including air temperature in urban areas such as Medan City. This study aims to analyze changes in air temperature in Medan City during and after the COVID-19 pandemic, especially related to social restriction policies such as PPKM. Temperature data was obtained from UPT BMKG Medan for the period 2020 to 2025 and analyzed using I-MR (Individual-Moving Range), Cusum, and EWMA (Exponentially Weighted Moving Average) methods. The results of the analysis are expected to be able to show significant temperature differences as a result of the decline in human activities during the pandemic as well as the trend of post-pandemic temperature changes. This study is important as a basis for future environmental planning and climate change mitigation policies.

Soil moisture is a crucial factor in agriculture that affects plant growth and crop productivity. In modern agricultural systems, accurate soil moisture monitoring is essential for optimizing water usage and enhancing the efficiency of automatic irrigation systems. This study aims to develop an Internet of Things (IoT)-based soil moisture monitoring system and evaluate the performance of three types of soil moisture sensors: Soil Moisture FC-28, Capacitive Soil Moisture Sensor, and Soil Moisture Hygrometer Module Sensor. The evaluation compares the accuracy and effectiveness of each sensor in measuring soil moisture. The research methodology involves measuring soil moisture in ten different soil samples using the three sensors simultaneously. The system is based on the ESP32 microcontroller, where data from the sensors are processed and displayed on an LCD Liquid Crystal I2C 20x4. Data analysis is conducted using the one-way ANOVA statistical method to determine whether there are significant differences among the measurement results of the three sensors.The results indicate that each sensor exhibits different measurement characteristics based on its working principle. The Soil Moisture FC-28 sensor, which operates on resistance, shows high sensitivity to changes in soil moisture but is susceptible to corrosion. The Capacitive Soil Moisture Sensor is more durable as it does not have direct contact with the soil, yet it requires more precise calibration. Meanwhile, the Soil Moisture Hygrometer Module Sensor provides more stable results under various environmental conditions. The one-way ANOVA analysis reveals no significant differences in the measurement results among the three sensors.

Immunization is an effort to provide immunity to infants and children by introducing vaccines into the body. This vaccine stimulates the body to produce antibodies that function to prevent certain diseases. The coverage of Complete Basic Immunization in Banda Aceh City/District from 2022 to 2024 has decreased each year by (43.9%) in 2022, (37.8%) in 2023, and (34.9%) in 2024. The immunization coverage is still very low and below the national target of (95%). To determine the factors influencing maternal behavior in basic immunization within the working area of the Banda Aceh City Health Center. Research. Quantitative research with a Cross Sectional Study approach using primary data. The population in this study consists of all mothers with infants aged 6-11 months within the working area of the Banda Aceh City Health Center. The sample in this study consisted of 200 respondents, with data collection methods using questionnaires and analyzed univariately to describe the distribution and proportion, as well as bivariately. Bivariate data analysis with Spearman correlation test. This study found a relationship between each variable and maternal behavior regarding basic immunization with the variables Attitude Toward Immunization (p=0.000), Subjective Norm of Immunization (p=0.000), Perceived Behavioral Control of Immunization (p=0.000), Actual Behavioral Control of Immunization (p=0.000). All variables are related to maternal behavior in basic immunization within the working area of the Banda Aceh City health center.

Principal This study aims to analyze the principal's leadership management in building the character of students at SD Negeri 27 Palembang.
