Student Worksheets (LKPD) are one of the teaching materials that play an important role in the learning process. In the data structure of mathematics subjects, LKPD is CTL-based with square and rectangular shapes. This research was conducted on grade IV students of SDN 106161 Laut Dendang. Elementary school students in the fourth grade were used as research participants. This study uses an analysis, design, development, implementation, and evaluation (ADDIE) model. The results of this study can be seen and proven by using the Likert scale to assess the material and aspects that are still being developed, namely: a) Validity that gets a score (4.8) from media experts and (4.43) from experts in materials. b) Efficiency, i.e. obtaining a score of 3.96 from students and 4.6 from teachers. c) Fairness of use of estimated N-Gain reaches value 0.8110. The study's findings, students' enthusiasm in learning math about square and rectangular shapes should be made easier for educators and prospective teachers. In addition, this development is expected to help students gain a deeper understanding of the subject matter they are learning, thereby increasing their interest in CTL-based LKPD exercises.

The minimum competency assessment is used in developing students' numeracy literacy skills to have 21st-century skills. However, students' difficulties in solving minimum competency assessment questions will cause unsatisfactory results. Therefore, it is necessary to analyze further students' difficulties in solving the minimum competency assessment questions, including mathematical communication skills. This study used qualitative research methods with descriptive analysis techniques to examine these difficulties. The data collection techniques used were observation, tests, and interviews. The research was conducted by giving students a minimum competency assessment test, and then the results were analyzed so that six research subjects were obtained. Then interviews were performed according to the guidelines that had been made for the six subjects. The results showed that subjects with high communication skill categories needed help compiling solution ideas and complete answers written by students. Then subjects in the medium category had difficulty in three indicators: linking the information given into mathematical concepts, compiling mathematical ideas, and generalizing. Meanwhile, subjects in the low category experienced difficulties in each indicator, and most did not answer the questions. So it is concluded that subjects with high communication ability categories have fewer difficulties when solving minimum competency assessment questions than subjects with medium and low levels.

Banyumas is one of the regencies that still experiences frequent fires. The fire caused physical or material losses. To minimize fire losses, many efforts can be made to prevent the occurrence of these potential causes, which are the cause of the failure of the firefighting process. This study aims to implement the Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA) methods in determining efforts to prevent fire suppression failures. The result of the FMEA is Risk Priority Number (RPN) values to assess critical potential causes that need to be analyzed using FTA. In this research, there are ten important causes of potential, namely burned assets, difficult assets to save, victims panicking, witnesses/owners were not present, officers slipping, water sources being far from the location, victims being rescued too late, victims being trapped, officers being hit by debris, and officers inhaled excess smoke (congested). The result FTA obtained eleven minimum cut sets, which can fail the firefighting process in the Banyumas Regency, namely lack of awareness from related agencies, the protection system is not up to the firefighting standard and lack of maintenance of the fire protection system, lack of knowledge about how to evacuate yourself, the water source is far from the location, the owner does not live in the place (location), the victim has responsibility for the assets saved, high-priority asset value, a witness has not reported because the incident is considered to be handled by the residents, fire smoke is thick and firefighters not using self-contained breathing apparatus (SCBA).
