Abstract

Penelitian ini bertujuan membuat media pembelajaran yang interaktif pada submateri peranan bakteri SMA kelas X dengan informasi tambahan berupa uji antibakteri ekstrak daun salam pada bakteri Shigella sonnei. Penelitian ini menggunakan pendekatan kualitatif dan kuantitatif. Metode yang digunakan adalah Research and Development (R&D) model 4D yang direduksi menjadi 3D, yaitu define (pendefinisian), design (perancangan), dan develop (pengembangan). Media divalidasi oleh lima orang ahli menggunakan angket validasi dan analisis validasi diadaptasi dari Aiken’s V. Selanjutnya dilakkan uji reliabilitas dilakukan menggunakan ICC (Intraclass Correlation Coefficient) menggunakan aplikasi SPSS. Media animasi PowToon dinyatakan layak digunakan dengan nilai minimum Aiken’s V yang diperoleh sebesar 0,87 dan nilai ICC sebesar 0,799 dengan kategori baik. Hal ini menunjukkan bahwa terdapat kesepakatan antar validator dalam menilai video animasi PowToon.Kata kunci: Aiken’s V; Media Pembelajaran; Metode R&D; PowToon; BakteriDevelopment of Powtoon Media for Sub Material Role of BacterialABSTRACTThe research aimed to create interactive learning media the sub-material of the role of bacteria on the tenth grade of Senior High School with additional information in the form of antibacterial test of the bayleaf on bacteria Shigella sonnei.

This study aimed to determine the effect of using the Quizizz application on the learning outcomes of the cognitive domain of grade V elementary school students on the animal respiratory system. The type of research used was quantitative research with a quasi-experimental design in the form of a nonequivalent control group design. The population of this study was all grade V elementary school students totalling 74 students. Samples were taken by convenience sampling technique consisting of the VA class with 25 students as the experimental class and the VC class with 24 students as the control class. Data collection was carried out using cognitive learning outcomes tests on the animal respiratory system. The data were then analyzed using an independent two-sample t-test, an Effect Size test, and an N-gain test. The results showed that: (1) there were differences in student cognitive learning outcomes between classes that used the Quizizz application and classes that did not use the Quizizz application with tcount > ttable, namely 3.8133 > 2.0139; (2) the use of the Quizizz application had a high influence on the learning outcomes of the cognitive domain of students with the results of an Effect Size of 1.08, high criteria; (3) the use of the Quizizz application could improve students' cognitive learning outcomes with N-gain results of 0.5172, medium criteria. Thus, it could be concluded that there was an effect of using the Quizizz application on the learning outcomes of the cognitive domain of grade V elementary school students on the animal respiratory system.

Abstract

Kemampuan konsep-konsep operasi hitung dasar pada sekolah dasar merupakan materi matematika yang sangat penting. Rendahnya penguasaan konsep-konsep operasi hitung dasar pada siswa sekolah dasar disebabkan rendahnya kemapuan pemahaman konsep, keterampilan berhitung dan kemampuan memecahkan soal cerita. Untuk itu, guru di sekolah dasar diharapkan dapat menjelaskan konsep-konsep operasi hitung dasar dengan benar. Namun pada kenyataannya, masih banyak mahasiswa yang belum memahami konsep-konsep operasi hitung dasar yang disebabkan dalam pembelajaran matematika kurang medapatkan perhatian. Tujuan Pennelitian adalah untuk mendeksripsikan kemampuan penalaran matematis konsep-konsep operasi hitung dasar yang berkaitan pemahaman konsep keterampilan berhitung pada bilangan bulat dan pecahan. Penelitian ini menggunakan pendekatan kualitatif deskriptif. Subjek penelitian adalah mahaisswa semester 2 PGSD FKIP Untan dan PGSD STKIP Singkawang pada Mata Kuliah Matematika Dasar. Objek penelitian adalah kemampuan penalaran matematis mahasiswa. Teknik analisis data meliputi tahapan reduksi data, penyajian data dan penarikan kesimpulan. Hasil penelitian ini yaitu rata-rata kemampuan penalaran matematis konsep-konsep operasi hitung dasar adalah 78,8%, dengan tingkat kemampuan 0 yaitu 1,3%, tingkat kemampuan I yaitu 3,9%, tingkat kemamupuan II yaitu 42,1%, tingkat kemampuan III yaitu 39,5% dan tingkat kemampuan IV yaitu 13,2%. Secara keseluruhan mahasiswa belum menguasai konsep-konsep operasi hitung dasar. Kesulitan mahasiswa dalam menguasai konsep-konsep operasi hitung dasar ditunjukkan dari beberapa kesalahan mahasiswa dalam menyelesaikan soal.Kata Kunci: Tingkat Kemampuan; Penalaran Matematis; Konsep Operasi Hitung Dasar The Level of Mathematical Reasoning Ability in the Concepts of Basic Calculation Operations of StudentsABSTRACTThe ability to understand the concepts of basic arithmetic operations in elementary schools is very important mathematics material. The low mastery of the concepts of basic arithmetic operations in elementary school students is due to the low ability to understand concepts, numeracy skills and the ability to solve word problems. For this reason, teachers in elementary schools are expected to be able to explain the concepts of basic arithmetic operations correctly. However, in reality, there are still many students who do not understand the concepts of basic arithmetic operations because mathematics learning does not receive enough attention. The aim of the research was to describe mathematical reasoning abilities, concepts of basic arithmetic operations related to understanding the concept of counting skills in whole numbers and fractions. This research used a descriptive qualitative approach. The research subjects were 2nd semester students of PGSD FKIP UNTAN and PGSD STKIP Singkawang in the Basic Mathematics Course. The object of research was students' mathematical reasoning abilities. Data analysis techniques included stages of data reduction, data presentation, and drawing conclusions. The results of this research were that the average mathematical reasoning ability for basic arithmetic operations concepts is 78.8%, with ability level 0 being 1.3%, ability level I being 3.9%, ability level II being 42.1%, ability level III is 39.5% and ability level IV is 13.2%. Overall, students had not mastered the concepts of basic arithmetic operations. Students' difficulties in mastering the concepts of basic arithmetic operations were shown by several students' mistakes in solving problems.
