Abstract

Penelitian ini merupakan pengembangan dari makalah yang telah dipresentasikan pada Seminar Internasional namun menggunakan tipe cermin yang berbeda dan berbasis Graphical User Interface (GUI). Penelitian ini bertujuan untuk menghasilkan simulasi pembentukan bayangan pada cermin cembung sebagai media pembelajaran Fisika yang dapat digunakan secara mudah dan efektif. Penelitian ini bersifat studi literatur, dengan menggunakan metode komparatif antara hasil simulasi dan hasil analitik. Simulasi dalam penelitian ini dibuat menggunakan aplikasi Scilab 5.5.0 dengan GUI Builder versi 3.0, dengan memanfaatkan konsep Fisika dan Matematika, di mana cermin cembung disimulasikan menggunakan persamaan parametrik untuk lingkaran, sedangkan sinar-sinar istimewa disimulasikan menggunakan persamaan garis lurus dengan gradien tertentu. Dalam penelitian ini disimulasikan pembentukan bayangan dari sebuah benda dengan tinggi 7cm yang diletakkan pada jarak 15cm dari sebuah cermin cembung yang memiliki radius kelengkungan -30cm. Cermin cembung yang disimulasikan dalam penelitian ini diasumsikan sebagai sebuah permukaan datar. Simulasi yang telah dibuat dapat berjalan dengan baik pada Scilab 5.5.0. Dari hasil simulasi ini, diperoleh tinggi bayangan sebesar 3.5cm dan jarak bayangan sebesar -7.5cm. Hasil perhitungan ini dibandingkan dengan hasil perhitungan secara analitik, dan diperoleh error perhitungan sebesar 0%, dengan kata lain hasil tersebut sama dengan hasil yang diperoleh dengan cara analitik, dan sekaligus membenarkan pernyataan bahwa proses pembentukan bayangan pada cermin cembung lebih mudah untuk digambarkan apabila cermin tersebut dianggap sebagai sebuah permukaan datar. Dengan demikian, simulasi ini dapat digunakan dalam proses pembelajaran Fisika.

Abstract

The implementation of this Community Service activity is motivated by the problems experienced by partners at SMP Kristen Payeti. The teachers in that school have not been able to take advantage of online learning applications such as Google Classroom and Google Meet. Therefore, to overcome the partner's problems, training was carried out by the PkM Team of Program Studi Pendidikan Matematika Universitas Kristen Wira Wacana Sumba, which aims to educate the teachers so that they can increase their knowledge and skills related to the use of the two applications. The training activities were carried out using lectures, demonstrations, and simulations using Google Classroom and Google Meet. While the stages of implementation include the preparation of training modules, preparation of training rooms, and implementation of training. The results of this service activity indicate that there is an increase in the knowledge and skills of teachers as trainees in using the two applications. Thus it can be concluded that the purpose of this service activity has been achieved. The follow-up carried out was to monitor the use of these two applications by teachers in the implementation of online learning.

Abstract

Universitas Kristen Wira Wacana Sumba is one of the universities that organizes online learning. This happened as a result of the COVID-19 pandemic. This situation requires all lecturers to be able to conduct online learning by utilizing the available facilities, namely Google Classroom and Google Meet, both permanent and adjunct lecturers. Permanent lecturers have used the application since the beginning of the covid-19 pandemic, while adjunct lecturers who held lessons this semester have never used the Google Classroom and Google Meet applications. If this is allowed, then learning will not be held properly. Therefore, this training is carried out in several stages, namely analyzing the needs of non-permanent lecturers, implementing activities, and following up. This training makes the online learning by adjunct lecturers can be carried out properly. Based on the results of the follow-up, the participants proposed further training on the use of Google Classroom, especially in making assignment assessment rubrics and quizzes.

Abstract

This study aims to describe the numeracy ability profile of high school elementary school students in Malumbi, East Sumba Regency. This numeracy ability was carried out at a grade 5 school in the high class area as a reference point used to analyze comparisons before finally moving on to a larger stage of research scope. This type of research is qualitative with the instrument used in data collection is the Numeral Test, namely the test uses EGMA (Early Grade Mathematics Assessment) measurements, interviews and observations. The results of the research on the school's numeracy skills which were collected through the numeration test found that elementary school students were in the low category with an average score of 18.43. This is caused by several factors such as textbooks which so far have only been provided while at school, learning media that are less interesting so learning becomes boring, and students are not used to being given story questions, so that students' numeracy skills in solving number pattern problems, recognizing and comparing numbers and there are still many mistakes in word problems, as well as follow-up on teacher competence in teaching mathematics so that there are no misconceptions in learning.
