Abstract

This study aims to identify the potential for landslides in the Ayudia housing location, Semarang. The data obtained in this study were apparent resistivity data using the geoelectric resistivity method of the Schlumberger configuration. Measurements were carried out on two tracks, namely the first track with a stretch length of 150 m and electrode spacing of 10 m and the second track with a stretch length of 75 m and electrode spacing of 5 m. Res2dinv software was used to display the resistivity value on each track so that a color image is seen that describes the change in resistivity in each rock layer. The results of the study indicated the identification of the location of the slip plane on the first track with a layer that is suspected to be the slip plane, namely limestone with resistivity values (307-939) Ωm and is at a depth of (19,9-26.9) m. This layer had a higher resistivity contrast than the top layer of the slip plane in the form of sandstone which can store water content. Thus, it could be concluded that the first track identified the potential for landslides to occur.

Populasi pada penelitian ini adalah seluruh siswa kelas IV dengan jumlah 71 terdiri dari kelas A, B, dan C.Teknik pengambilan sampel menggunakan purposive sampling dan terpilih kelas IVB dengan jumlah 24 siswa sebagai kelas eksperimen. Instrumen yang digunakan dalam penelitian adalah tes kemampuan pemahaman konsep dan angket respon siswa. Teknik analisis data yang digunakan dalam penelitian ini adalah uji t untuk mengetahui perbedaan kemampuan pemahaman konsep siswa SD antara sebelum dan sesudah menggunakan model pembelajaran CUPs pada materi sumber energi dan analisis persentase deskriptif untuk mengetahui respon siswa terhadap model pembelajaran CUPs yang diterapkan. Hasil penelitian menunjukkan bahwa (1) terdapat perbedaan kemampuan pemahaman konsep siswa antara sebelum dan sesudah menggunakan model pembelajaran CUPs dengan hasil thitung = 7,37302> ttabel = 2,07387. (2) Respon siswa positif terhadap model pembelajaran CUPs yang telah diterapkan dengan persentase 77% kategori baik sekali. Dengan demikian dapat disimpulkan bahwa terdapat pengaruh model pembelajaran Conceptual Understanding Procedures (CUPs) terhadap kemampuan pemahaman konsep siswa kelas IV SD pada materi sumber energi.The Effect of Conceptual Understanding Procedures (CUPs) Learning Model on Conceptual Understanding Ability of Fourth Grade Elementary School Students on Energy Source MaterialsAbstractThis study aims to determine the effect of the Conceptual Understanding Procedures (CUPs) learning model on the conceptual understanding ability of fourth grade elementary school students on energy sources. The type of research used was quantitative research with experimental research methods (Pre-experimental design). The research design used was one group pretest-posttest design. The population in this study were all fourth grade students with a total of 71 consisting of classes A, B, and C. The sampling technique used the purposive sampling and selected class IVB with a total of 24 students as the experimental class. The instruments used in the study were a test of the ability to understand concepts and student response questionnaires. The data analysis technique used in this study was the t-test to determine the difference in the conceptual understanding ability of students between before and after using the CUPs learning model on energy sources and descriptive percentage analysis to determine student responses to the CUPs learning model applied. The results showed that (1) there was a difference in the conceptual understanding ability of students before and after using the CUPs learning model with the results tcount = 7.37302> ttable = 2.07387. (2) Positive student responses to the CUPs learning model that has been applied with a percentage of 77% in the very good category. Thus, it could be concluded that there is an effect of the Conceptual Understanding Procedures (CUPs) learning model on the conceptual understanding ability of fourth grade elementary school students on energy sources.

Abstract

The partners of this service activity are teachers throughout West Kalimantan with partner problems, namely a decrease in the quality of learning in Merdeka Learning. Quality learning cannot be separated from the ability of teachers as planners, implementers, facilitators, and evaluators. One of the efforts that can be done to improve the quality of learning is to carry out lesson study. The purpose of this Community Service activity is the formation of a learning community that consistently makes self-improvement in the learning process to reduce the decline in learning outcomes in Merdeka Learning. The method of implementing this  activity is mentoring lesson study to teachers throughout West Kalimantan. The implementation follows the method of implementing lesson study, namely planning, implementation, and evaluation. Regarding the usefulness of the activity to the 300 participants, data obtained from 300 people felt that this activity was very useful or equivalent to 100% of the number of participants. This shows that the activity of "Lesson Study as an Effort to Improve the Quality of Learning in Independent Learning" has provided positive benefits for participants and its benefits have been felt. The supporting factor for this activity is the enthusiasm of teachers who take part in the service program activities carried out. The inhibiting factor of service activities is the limited time for carrying out activities

Abstract

This study aims to describe the mathematical communication abilities of fifth grade students on the material of flat shapes in terms of the gender of students at SDN 84 Singkawang. The research used is descriptive quantitative research. The population of this study was the fifth grade students at SDN 84 Singkawang consisting of VA and VB classes, which consisted of 44 students. The data collection technique used was the test technique and the data analysis technique used was quantitative descriptive analysis with percentages. The results showed that mathematical communication skills in terms of gender where the mathematical communication skills of fifth grade male students in solving problems, subjects with high abilities were able to fulfill all indicators of students' mathematical communication abilities. Subjects with moderate ability are less able to explain ideas, everyday situations and mathematical relationships in writing with pictures. While the mathematical communication abilities of fifth grade female students in solving questions on subjects with high abilities were able to fulfill all indicators of students' mathematical communication abilities. Subjects with moderate ability are less able to explain ideas, everyday situations and mathematical relationships in writing with pictures. Meanwhile, subjects with low abilities are less able to explain ideas, everyday situations and mathematical relations in writing with pictures and communicate the conclusions of answers to problems according to the results of the questions. Thus it can be concluded that students' mathematical communication abilities in terms of gender in this study averaged 74% in the moderate category.
