The background of this research is the importance of mathematics in daily life and the difficulties experienced by students in understanding mathematical concepts, especially division. This study aims to analyze the difficulties of students in solving integer division using the porogapit method in grade IV of SD Negeri Legok II, Indramayu Regency. This study uses a qualitative approach with a descriptive method. The research subjects were 6 people who were selected using the purposive sampling technique. Data was collected through observation, interviews, tests, and documentation. Data analysis uses qualitative data analysis consisting of data reduction, data presentation, and conclusion drawn. The results showed that students experienced difficulties in three main aspects: understanding problems, performing division calculation operations, and solving problems. Most students have difficulty in the division calculation operation even though they already understand the porogapit method. This difficulty has an impact on the understanding and application of mathematical concepts in daily life. This research provides recommendations for improving learning methods that can improve students' understanding and ability in integer division

Teachers play a determining role in students' success in achieving learning goals. Therefore, Pedagogical Content Knowledge is an ability that teachers and prospective teachers must have. This research aims to describe the Pedagogical Content Knowledge profile of prospective mathematics teachers in collaborative online learning, especially in courses evaluating mathematics learning processes and outcomes. This research is descriptive qualitative research. Prospective mathematics teacher students who contracted courses in evaluating the process and results of mathematics learning from Wiralodra University and Nahdlatul Wathan University of Mataram, were the subjects of this research. The instruments used in this research were a test of understanding the concept of evaluating mathematics learning processes and outcomes, questionnaires, and learning documentation via the Phytagoras LMS. The data analysis techniques used include data reduction stages, data presentation, and drawing conclusions. Based on the research results, it was found that students in the mathematics learning process and outcome evaluation course whose lectures were held collaboratively online had a very good Pedagogical Content Knowledge profile and gave a positive response to the implementation of collaborative online learning.

The limited student understanding of arithmetic sequences and series, along with the minimal use of interactive Android-based learning media, served as the foundation for this study. The main objective of this research was to develop and evaluate the effectiveness of an Android-based learning application called BETAMATH in enhancing students' comprehension of the topic. This study employed a Research and Development (R&D) approach, using the 4D development model, which includes the stages of Define, Design, Develop, and Disseminate. The developed product was validated by subject matter experts, media specialists, and pedagogical experts, and was tested on tenth-grade students. Validation results indicated that BETAMATH is suitable for use in the classroom. Practicality testing revealed that the application is easy to use, based on student feedback and teacher observations. The effectiveness of the media was confirmed by a significant improvement in students' understanding, as shown by pretest and posttest results. Therefore, BETAMATH is considered valid, practical, and effective for improving student understanding of arithmetic sequences and series, and holds promise as an innovative alternative to support mathematics instruction in schools.

The work of each head of family in the Anjatan Baru Village community includes farming, entrepreneurship, livestock farming, civil servants, and others. Activities between residents and early childhood are quite good. Because of the large number of residents, the amount of household waste produced is also increasing. However, this is due to the lack of awareness of residents to dispose of waste in its place and manage the waste properly. Most residents still litter, especially in the drainage area which should be a water drainage channel, and residents still bury waste in the ground or burn it which may have a negative effect on the surrounding life. This problem causes clogged drainage channels, which has the potential to cause flooding, especially during the rainy season. Therefore, this program aims to increase public awareness of the importance of environmental cleanliness and good drainage maintenance. Activities carried out in this program include counseling, environmental cleaning, and procurement of trash bins. Counseling aims to provide information to the public about the right way to manage waste and the importance of maintaining environmental cleanliness. In addition, environmental cleaning is carried out to reduce the amount of scattered waste and improve the condition of existing drainage. The provision of trash bins is expected to make it easier for the community to dispose of trash in its place, thereby reducing the possibility of blockages in the drainage channels. The approach used in this supporting program is a qualitative approach in the form of surveys and observations. This is done to directly find out the condition of the cleanliness of the drainage channels and the environment around Anjatan Baru Village and to find out the drainage channel maintenance activities carried out by residents. Based on the analysis of the situation in Anjatan Baru Village. So we propose one of the supporting programs for the Real Work Lecture (KKN) activity in the form of drainage maintenance and procurement of trash bins. In addition to inviting the community to work together to clean the surrounding environment and drainage channels, this activity also provides counseling to the community that sediment and garbage that clogs drainage channels can cause water flow to be blocked so that it can cause flooding. With this drainage maintenance program and procurement of trash bins, it is hoped that the community will realize the importance of good drainage conditions and clean environmental conditions so that flooding can be avoided. The target of this program is the community of Anjatan Baru Village, especially people whose drainage conditions are blocked by garbage. The output target to be achieved in addition to compiling activity reports is to increase public awareness of the importance of a clean environment and cleaner drainage conditions that are not clogged with garbage. After this activity is completed, an evaluation will be carried out regarding the obstacles encountered during the implementation of the activity and how residents responded to the activity. Because this activity is carried out once, the evaluation of the implementation of the activity can be used as a learning experience so that obstacles during the first stage of the activity can be minimized in the second activity. The level of success of this activity itself is based on the condition of the environment and drainage channels before and after the implementation of the activity.
