Abstract

Sumber energi merupakan sesuatu yang terjadi pada sekitar yang dapat menghasilkan sebuah energi. Sumber energi dibagi menjadi dua bagian,  yaitu sumber energi terbarukan dan  sumber energi tidak terbarukan. Sumber energi terbarukan yakni energi yang dapat dikembangan atau diperbarui dengan mengkolaborasi suatu energi, sedangkan energi tidak terbarukan yakni energi yang tidak dapat diperbarui. Contoh dari sumber energi tidak terbarukan yaitu minyak bumi, gas alam, batu bara, dan nuklir. Dalam Penelitian ini akan menggunakan metode studi literatur dari berbagai macam jurnal yang telah dikumpulkan. Jurnal tersebut berisi tentang informasi dari bahan satu dengan yang lainya sehingga dapat mengetahui perbedaan dari masing masing jurnal. Kincir angin ialah sebuah alat yang dapat dimanfaatkan oleh manusia, kekuatan angin untuk diubah menjadi energi mekanik sehingga akan terjadi pergerakan pada alat tersebut. Pada proses ini yang menghasilkan energi gerak menjadi energi energi listrik. Untuk membuat kincir angin membutuhkan alat dan bahan yang harus disusun melalui sebuah proses, sehingga dapat diketahui proses cara kerja dari kincir angin tersebut.

Abstract

Physics is a science that studies objects, their motion, and their benefits to human life. Measurement in physics is the activity of comparing the measured quantity with another quantity that has been established as a unit. Regular objects, such as spheres, blocks, and cubes, have shapes that can easily be calculated using geometric formulas. In contrast, irregular objects pose a greater challenge because their shapes cannot be simply represented by geometric equations. This study aims to identify the measurement techniques used for both regular and irregular objects in terms of accuracy and efficiency. The methods discussed include techniques for determining the volume and density of objects. This experiment provides better insights into the selection of appropriate measurement methods based on the characteristics of the object being measured. The results of the experiment show that measuring regular objects is easier with simple measuring tools, while irregular objects require more careful and precise approaches to obtain accurate results. Measurement errors can occur, especially when measuring irregular objects, which can be minimized by using proper measuring tools and following correct procedures.

Abstract

The purpose of this research is to test the validity and feasibility of physics textbooks that have been developed based on Problem Based Learning (PBL) on Newton's gravitational force material. This research uses development research methods. The validation sheet is used as a research instrument. The validation sheet was validated by two experts and declared valid according to predetermined criteria. Textbook validation data was collected from two experts, one textbook media expert and one physics material expert. There are two aspect criteria that are tested for validity, the form of dialogical and interactive presentation of language and the contextual nature of textbooks. The purpose of this research approach is to describe the effectiveness, validity and feasibility of using physics textbooks. The research results obtained are the percentage of aspects of dialogic and interactive language validation as well as aspects of contextual nature that have been tested by material experts obtained an average percentage of 87.5%, which means that the physics textbooks that have been developed are included in the feasible criteria. The results of the research tested by media experts on aspects of dialogic and interactive language as well as on aspects of contextual nature both obtained an average percentage of 100%. This means that a physics textbook based on Problem Based Learning (PBL) on Newton's gravitational force is very feasible to be tested based on validity testing by one material expert and one media expert.

Abstract

Penelitian ini bertujuan untuk mengembangkan dan menguji validitas buku pedoman mengenai differentiated instruction untuk penguatan Profil Pelajar Pancasila bagi guru IPA. Penelitian ini menggunakan pendekatan penelitian dan pengembangan (R&D) dengan model 4D, yang meliputi tahapan Define, Design, Develop, dan Disseminate. Teknik pengumpulan data dilakukan melalui lembar validasi oleh para ahli dan dianalisis secara deskriptif. Hasil validasi menunjukkan bahwa komponen konstruk memperoleh rata-rata skor sebesar 71,5%, komponen isi 75%, dan komponen bahasa 78%, yang seluruhnya berada pada kriteria valid. Rata-rata skor validasi keseluruhan adalah 74,8%, sehingga buku pedoman dinyatakan layak digunakan. Berdasarkan hasil tersebut, buku ini dapat menjadi acuan bagi guru IPA dalam mengimplementasikan pembelajaran berdiferensiasi untuk mendukung integrasi nilai-nilai Pancasila dalam kegiatan pembelajaran di kelas. Kata kunci: buku pedoman; differentiated instruction; profil pelajar pancasila
