Abstract

This study aims to determine the working principle of the Global Positioning System (GPS) as a technology that applies the concept of relativity, and its application to determine the geographic location of students' addresses. This type of research is a literature study. In general, the GPS system has three main components, namely the ground segment (control station), the space segment (satellite), and the user segment (receiver device). GPS determines the receiver's position using the trilateration method from a minimum of four satellites that are always visible from any point on Earth at any time. The results of the study state that information from three satellites is needed to determine location, while the fourth signal is needed to determine time accurately. Relativity causes the GPS system to experience a time lag. The relative motion of the satellite to the earth causes the time on the satellite to be slower than earth time, while earth's gravity makes the satellite time move faster than earth time. The novelty of the results and discussion of the study conducted is to find the coordinates of student addresses, thus facilitating mapping of student residences in the city of Lubuklingau and its surroundings.

Abstract

Abstrak This study aims to measure the learning outcomes of fifth-grade students at Trans Muara Megang Public Elementary School after implementing a problem-based learning model assisted by audiovisual media. This study is a quasi-experimental study with a one-group pretest-posttest design. The subjects of this study were 21 fifth-grade students at Trans Muara Megang Public Elementary School. Data collection techniques were carried out by administering tests to students and documenting the results. The research findings indicate that there was an improvement in students' learning outcomes after the implementation of the PBL model assisted by audiovisual media in the social studies subject matter on the causes of changes in natural conditions and efforts to address them. Based on the data analysis, the average pretest score was 58.82 and the average post-test score was 78.33, indicating an increase in student learning outcomes of approximately 19.51 after the implementation of the PBL model assisted by audiovisual media. Based on the z-test analysis, the value of Zcount ≥ Ztable was obtained, namely 6.59 ≥ 1.64. Therefore, it can be concluded that the learning outcomes of Grade V IPS students after the implementation of the PBL model assisted by audiovisual media were significantly improved. Keywords: Learning Outcomes, PBL,Social Studies   Penelitian ini bertujuan untuk untuk mengukur ketuntasan hasil belajar IPS peserta didik kelas V SD Negeri Trans Muara Megang setelah penerapan model problem based learning berbantuan media audiovisual. Penelitian ini merupakan penelitian eksperimen semu dengan desain one group pretest - posttest. Subjek penelitian ini adalah peserta didik kelas V SD Negeri Trans Muara Megang sebanyak 21 orang peserta didik. Teknik pengumpulan data dilakukan dengan memberikan soal tes kepada peserta didik dan dokumentasi. Hasil penelitian menunjukkan bahwa terdapat peningkatan hasil belajar peserta didik setelah diterapkannya model PBL berbantuan media audiovisual pada mata pelajaran IPS materi faktor penyebab perubahan kondisi alam dan upaya mengatasinya. Berdasarkan analisis data yang telah dilakukan, rata rata skor pre-test yaitu sebesar 58,82 dan rata-rata skor post-test sebesar 78,33 sehingga terdapat peningkatan hasil belajar peserta didik sekitar 19,51 setelah diterapkannya model PBL berbantuan media audiovisual. Berdasarkan analisis uji-z, diperoleh nilai Zhitung ≥ Ztabel, yaitu 6,59 ≥ 1,64. Sehingga dapat disimpulkan bahwa hasil belajar IPS Kelas V SD Negeri Trans Muara Megang setelah diterapkan model PBL berbantuan media audiovisual signifikan tuntas.
