Rapid technological developments encourage the banking sector to continue to innovate so as not to be left behind. Tight competition in this industry is caused by customers' freedom to choose products and services that are considered more profitable. This phenomenon is known as Customer Churn, which is a condition where customers choose not to continue subscribing to a particular company. The method applied uses a machine learning approach and customer segmentation approach. The churn analysis results show that the machine learning model, especially the random forest model, has the highest level of accuracy with an F1-Score of 91%. This model has the potential to reduce churn rates from 20.4% to 5.61%, illustrating its positive impact. Apart from that, for the clustering results, the K-Prototype model was obtained for the clustering model with the highest Silhouette Score number of 0.1557 and 4 clusters were obtained.

The Freedom to Learn Program has various innovative programs in the education development. The old educational model is now transformed into a more flexible, explorative, and borderless. Thus, the readiness of the teacher is very important. The Mover Teacher Program is a challenge where teachers are required to be more creative and adaptive to change. However, this concept has not been fully understood by teachers outside Java Island. Therefore, the training of Mover Teachers needs to be carried out in SMP N 2 Barru South Sulawesi. This activity is carried out via online with expert as the initial stage and offline, mentoring as the final stage. With these two methods are expected to get more effective results to increase the capacity of teacher resources in Barru. The output of this dedication is that teachers can think innovatively and be ready to become mover teacher to success independent learning program.

One of the primary school subjects that is compulsory for students to study is Natural Sciences (IPA). In conducting the learning process a teacher needs to prepare models and methods as well as what media is chosen to help the teacher deliver the material. So that students can receive the material well and work the matter properly and improve the student's learning outcomes from before learning to after learning. This research is to find out what models and media can be applied in IPA learning on simple aircraft material. This article is written using the research method of a library review. This research includes the study of libraries to gather information and analyze literature. Of the eight articles scanned with one or two using similar learning models and other learning media showed positive results for students and teachers. Improved student learning about simple aircraft material became better. Some models and learning media on simple aircraft material are a reference to teachers in implementing the IPA learning process well and achieving the entire learning plan.

Students’ ability to communicate their mathematical ideas in various ways is not as expected. It is difficult for teachers to improve students’ mathematical communication skills by improving learning styles, improving the learning atmosphere, and using appropriate learning models. Therefore, it is important to know the factors that influence students’ mathematical communication abilities. The aim of this research is to describe the factors that influence students’ mathematical communication skills. The subjects of this research were four children aged approximately 11 years who live in Hamparan Perak District. The data collection techniques used were observation and interviews. Data were analyzed using a qualitative approach. The results of the research show that the factors that influence students’ oral communication skills are study partners, self-confidence, shyness, nervousness, group learning atmosphere, learning time, and gender. Factors that influence students’ written communication skills include the inability to write down known information and be asked about it, lack of concentration in studying and inability to understand the content, as well as question difficulty, which includes the level of composure and composure in solving questions.

Learning media is an important learning tool to consider in the learning process. The presence of learning media can make learning more interesting and active, so that the use of media can help increase student achievement and learning motivation. The presence of learning media in citizenship learning content is considered very important to reduce the verbality of citizenship learning material. The aim of this research is to develop wordwall-based citizenship learninglearning media that can be used by teachers to transfer material and carry out learning evaluations. The type of research used in this research is development research (Research and Development). Research and development is research that aims to produce a product that comes from research and testing the product that has been developed. The development research model is the ADDIE model which consists of five stages of development research. The five stages are analysis, design, development, implementation and evaluation. In this research, the development stage will be discussed up to the ADD stage. The subjects in this research were media experts, material experts, and three 6th grade elementary school students to test the level of appropriateness of the media. Based on the validation test, it can be seen that through the two stages of validation by experts, the wordwall media was declared very suitable for use in learning. This is because wordwall media can have a positive influence on the classroom climate and student learning outcomes.
