Abstract

The learning process can use the surrounding environment as a learning resource with a view to optimizing student learning outcomes on ecosystem materials. This research is classroom action research (CAR) which is made in 2 cycles where each cycle consists of 4 stages, namely planning, action, observation and reflection. The materials used are class VII-B students with a total of 26 students. The results showed that from cycle I to cycle II, student learning outcomes increased. The percentage of passing learning outcomes in the first cycle is 65% and the average grade is 67, while in the second cycle it is 88% and the average grade is 87. learning increased by 20 points. Utilizing the environment as a learning medium can make teaching and learning activities more memorable, because students are faced with real situations. The lessons learned by students will be more concrete, more precise, and their authenticity will be accountable so that it can be concluded that learning by using the environment as a learning resource can improve student learning outcomes.

Abstract

This study analyzes the effect of atmospheric drag perturbation at two different magnetic index (active and severe storm) conditions, on the motion of NOAA 15 weather satellite, the Celestial Mechanics software results were plotted with the assistance of the MATLAB program. From the results it is noticed that for short period of time the effect of atmospheric suppression disturbance at different geomagnetic activity had the same effect on the orbital elements and orbital motion components , for a long period there is a slight variation in the effect of the perturbation at two different geomagnetic activities, which can be seen in the orbit's inclination as well as its size and shape. The results demonstrated that motion components were significantly impacted by geomagnetic activity over relatively extended time scales.

Abstract

The aim of this research is to determine the effect of using comic media on students' reading interest at SD 1 Menawan. This research uses quantitative methods with the research method being Quasi Experiment (quasi experiment). Data collection techniques used in this research include interview guides, comics and questionnaires. The respondents in this study were all students in grades IV and V as the control and experimental classes at SD 1 Menawan. Data analysis techniques were processed and analyzed using SPSS 20 data processing software. The research data obtained was carried out by normality test, hypothesis test, and t-test. The sig value was obtained from the results of the t-test of the two variables of the experimental class and the control class of 0.000 < 0.05, it can be concluded that Ho was rejected, which means that the use of comic media as a teaching material has an effect on the increase in students' interest in reading at SD 1 Menawan.

Abstract

This study aims to estimate the population in Minahasa Regency at t=7 or t=8 in 2026-2027 using a logistic population model. Based on data obtained from the Minahasa Regency Central Statistics Agency (BPS) from 2019 to 2022, it can be assumed that the capacity limit (K) = 400,000. The results of this research show that the accurate model to use in determining the estimated population of Minahasa Regency is the model with k = 0.0588644467, and the relative growth rate is 5.88% per year. Then, using the logistic method, the general form of the solution is obtained, namely P(t )=400,000/(e^(-0.0588644467t) (0.16921458)+1). Furthermore, the results obtained show that the predicted population of Minahasa Regency in 2026-2027 is 359,690 and 361,774 people.
