Abstract

Kompetensi mengajar sebagai acuan dalam mengelola pembelajaran. Kompetensi mengajar tidak secara instan bisa dimiliki oleh guru bahkan calon guru pun harus bisa menguasai kompetensi mengajar. Implementasi kompetensi mengajar dapat dilakukan melalui field study (praktik mengajar). Tujuan penelitian ini adalah mendeskripsikan field study dan hasil belajar calon guru IPA. Metode yang digunakan dalam penelitian adalah single subject research. Variabel penelitian terdiri dari field study dan hasil belajar calon guru. Pengumpulan data penelitian menggunakan observasi dan dokumentasi. Data penelitian dianalisis menggunakan uji t paired. Hasil penelitian menunjukkan (1) field study (praktik mengajar) calon guru dinyatakan baik dalam pelaksanaan kegiatan awal pembelajaran, kegiatan inti pembelajaran dan kegiatan penutup pembelajaran, (2) ada pengaruh pembelajaran field study terhadap hasil belajar calon guru IPA dengan nilai signifikasi 0.000 < 0.05. Dengan demikian, penerapan field study terbilang baik untuk diterapkan dalam pembelajaran karena sebelum calon guru melakukan field study, dosen pengampu memberi contoh terlebih dahulu tentang teknik mengajar, merencanakan pembelajar hingga mengontrol pembelajaran dan melakukan evaluasi pembelajaran.

Abstract

This research aims to examine the potential of light bricks made from plywood industry waste as a construction material with sound-dampening capabilities. Plywood sawdust waste was chosen as a mixing material due to its abundant availability and its lightweight and porous characteristics, which are expected to enhance the acoustic performance of the bricks. In this study, variations in the composition of plywood powder in bricks were made with the aim of evaluating its effect on physical, mechanical, and acoustic properties. The materials needed for this research are sand, cement, water, and plywood powder. The process of mixing and molding the bricks is done manually. Bricks are dried for 28 days to ensure the mechanical strength and stability of the bricks. Testing was conducted to evaluate physical properties through mass measurement and density testing, mechanical properties through compressive strength testing, and acoustic properties through sound absorption coefficient testing at various frequencies. The research results show that the addition of plywood powder significantly affects the reduction of brick density, making it lighter compared to conventional bricks. Based on the compressive strength test results, it is known that the addition of plywood powder has reduced the compressive strength value of the brick. However, bricks with an additional 10% and 20% volume of plywood powder still meet the minimum compressive strength requirements based on SNI 03-0349-1989. Meanwhile, the results of the sound absorption coefficient test indicate that the increase in the sound absorption coefficient is not significant, presumably due to the structural properties of the bricks that still require porosity optimization. In conclusion, lightt bricks with plywood powder filler have the potential to be environmentally friendly and lightweight construction materials, but they require improvement in optimizing sound absorption for more specific applications in buildings with acoustic insulation needs.

Abstract

The role of learning media was important to helped students for understood learning proccesed. The selection of learning media was concerned about the suitability of students and the material being studied. The earth layers materials in science lesson was materials that needed a learning media. For this reason, researchers developed a flash card puzzle learning media. This study aims to produced flash card puzzle learning media on class VII SMP/MTs earth layer material that is valid and practical. This development used the ADDIE development model which had step of analize, design, development, implementation, and evaluation. The validity test was conducted by media assessment by validator, they were media expert, material expert, and science teachers. The practicality test was carried out by assessing the activities of teachers (researchers) when was using the media, assessing the activities of students when was using the media, and filling out questionnaires of student responses about satisfaction after used flash card puzzle media. The results of the validity test and practicality test of flash card puzzle media obtained an average score of 3.44 with very valid criteria and 87% with very practical criteria. Based on these data, the development of flash card puzzle media learning media was valid and practical to be used in the learning process of class VII earth layer material.

Abstract

Learning media had an important role in the learning process. The selection of appropriate learning media can increased students motivation and understanding in the teaching and learning process. One of the media that often used was PowerPoint, which can presented text, images, and animated videos. However, in one SMPN Riau, still used whiteboard as a learning. The aims of this research was to produced PowerPoint-based interactive learning media on the excretory system material that was feasible to used. This research followed the ADDIE development procedure through analysis, design, development, implementation, and evaluation. The validator declared the results of this study were very valid with an average score of 3.72. The practical test results obtained from the implementation of the media usage sheet and questionnaire responses of students achieved an average score of 92.16%, indicating very practical criteria. The effectiveness of the media was then evaluated based on the results of the post-test, which showed an average value of 87.5, which indicated very effective criteria. Thus the PowerPoint-based interactive learning media that has been developed is deemed fit to be used as a learning media.
