Abstract

Bulu ayam merupakan limbah yang dihasilkan dari ternak ayam potong yang memiliki nilai protein cukup tinggi tinggi. sehingga dapat digunakan sebagai bahan dasar pakan ikan lele (Clarias gariepinus). Penelitian ini menggunakan substrat limbah bulu ayam, bakteri Bacillus subtilis, dan ikan lele (Clarias gariepinus). Pada penelitian ini bertujuan untuk memanfaatkan limbah bulu ayam menjadi pakan ikan dengan fermentasi bakteri Bacillus subtilis, kemudian untuk mengetahui kuantitas proksimat pada tepung bulu ayam, dan pengaruh pakan tepung bulu ayam terhadap pertumbuhan bobot ikan lele (Clarias gariepinus). Penelitian ini menggunakan fermentasi selama 5 hari, dan dibagi menjadi 4 perlakuan, antara lain: P0 : Tepung bulu ayam non fermentasi; P1 : Tepung bulu ayam 250gram/250ml bakteri Bacillus subtilis; P2 : Tepung bulu ayam 250gram/500ml bakteri Bacillus subtilis; dan P3 : Tepung bulu ayam 250gram/750ml bakteri Bacillus subtilis. Parameter yang digunakan adalah uji proksimat yang meliputi kadar protein, kadar lemak, kadar karbohidrat, kadar serat dan bobot ikan lele (Clarias gariepinus) setelah diberikan pakan tepung bulu ayam. Hasil penelitian menunjukkan bahwa perlakuan P2 dapat meningkatkan kuantitas pakan ikan dengan hasil kadar protein sebesar 35,3%, kadar karbohidrat sebesar 4,42% dan lemak sebesar 2,09%, serta mampu   meningkatakan bobot ikan lele (Clarias gariepinus) sebesar 26,6 gram.

Abstract

This research is a literature study (library research) that uses a qualitative approach. The aim of this research is to examine the extent to which technology plays a role in mathematics learning from the perspective of the epistemology of mathematical philosophy. The study of the epistemology of the philosophy of mathematics that is being discussed is how does the development of the philosophy of mathematics influence technology? What is the relationship between the philosophy of mathematics and technology-based learning? As well as examples of technology-based mathematics learning models. The results and discussion of this article can be concluded: Philosophy is a science that has a close relationship in human life.The philosophy of mathematics influences the development of technology in general. Technological developments influence the development of learning. From a learning perspective, technology is not only something related to machines, but also related to people, ideas and activities in learning. The use of technology in the form of hardware and software can improve student learning outcomes. Currently, there are many software tools available for use in learning, such as GeoGebra. Choosing the right learning model and mathematics learning technology can make learning more effective

Abstract

This research aims to improve students' ability to understand mathematical concepts at SMP Negeri 21 Medan by applying the Discovery Learning learning model. This research is classroom action research carried out in two cycles. The subjects of this research were students of VIII-5 SMP Negeri 21 Medan with a total of 31 students. Each cycle consists of 4 stages, namely planning, implementation, observation/evaluation and reflection. The results of the research show that students' ability to understand mathematical concepts can increase after implementing the discovery learning model. The increase was obtained through the average student score from 57.52 in the poor category, increasing in the first cycle to 68.11 in the poor category and increasing in the second cycle to 77.81 in the sufficient category. Improvement was also obtained from students' classical abilities, where in the first cycle 16 students (51.61%) completed it. Then, in cycle II, it was found that 27 students (87.1%) had completed classically. So it is concluded that the application of the Discovery Learning learning model can improve the ability to understand mathematical concepts of students in class VIII SMP Negeri 21 Medan.

Abstract

Dalam proses pendidikan pembelajaran berdiferensiasi memiliki peran dalam pemenuhan kebutuhan individual peserta didik. Tingkat kesiapan, minat dan gaya belajar yang berbeda-beda tidak menutup kemungkinan bagi peserta didik untuk tetap menciptakan proses berfikir tingkat tinggi dalam pembelajaran. Dalam penelitian ini dilakukan pengembangan instrumen penilaian berbasis HOTS pada materi virus. Tujuan penelitian ini adalah mengembangkan instrumen penilaian pada materi virus berdasarkan tingkat pemahaman yang berbeda pada peserta didik SMA kelas X IPA. Metode yang digunakan adalah research dan development (R&D) dengan desain penelitian model 4-D, meliputi tahap Define, Design, Develop dan Dessaminate. Hasil yang diperoleh untuk validitas teoritis terhadap 1 dosen sebagai ahli pendidikan dan 2 guru sebagai ahli materi adalah sebesar 89,03 %, hasil validitas empiris terhadap 110 siswa SMA kelas XI dan XII  menyatakan r hitung lebih besar dari r tabel, nilai reliabilitas instrumennya sebesar 0,977, analisis tingkat kesukaran soal menyatakan 30% (mudah), 63,33% (sedang) dan 6,67% (sukar), analisis daya pembeda menunjukkan 93,33% cukup memadai dan 6,67% lemah. Dapat disimpulkan bahwa soal yang digunakan dalam pengembangan instrumen penilaian sudah sangat baik dan memenuhi kriteria HOTS sehingga dapat digunakan sebagai instrumen penilaian materi virus kelas X SMA. Implikasi dari penelitian ini adalah agar siswa SMA terlatih untuk memecahkan soal dengan berfikir kritis.

Abstract

This study aims to develop Augmented Reality (AR) learning media based on Assemblr Edu for the topic of flat-faced geometric shapes and to determine its feasibility, practicality, and impact on students' interest and learning outcomes. The research method used is Research and Development (R&D) with the 4D development model, which includes Define, Design, Develop, and Disseminate. The subjects of the study were eighth-grade students at SMP Swasta Cerdas Murni during the 2024/2025 academic year. Research instruments consisted of expert validation sheets, learning interest questionnaires, teacher response questionnaires, and learning outcome tests (pretest and posttest). The results of expert validation on the material obtained an average score of 84%, and media expert validation scored 95%, both categorized as "Very Valid," while teachers' responses to the learning media scored 84%, categorized as "Very Practical”. Based on the data analysis results, there was an increase in the average student learning outcomes from 59.11 in the pretest to 83.75 in the posttest, with a significance value of 0.000 < 0.05, indicating a significant improvement in learning outcomes. In addition, students' learning interest also increased from an average score of 43.75 to 62.71, with a significance value of 0.000 < 0.05, indicating a significant increase as well. Therefore, the Assemblr Edu-based Augmented Reality learning media is deemed feasible, practical, and effective in enhancing students' interest and learning outcomes in the material of flat-sided geometric shapes and can serve as an innovative alternative media in mathematics learning at school.
