Abstract

Al-Quran adalah pedoman hidup umat islam. Di dalamnya mengandung aqidah, syariah dan akhlak. Al-Quran juga merupakan sumber ilmu pengetahuan. Banyak pengetahuan yang bersumber dari Al-Quran bertujuan untuk memberi pemahaman kepada manusia. Agama islam memerintahkan agar umatnya wajib menuntut ilmu. Semua ilmu tersebut berpangkal dari Al-Quran dan bermuara pada ketakjuban akan kekuasaan Allah. Al-Quran sebagai firman Allah berbicara tentang matematika. Konsep-konsep matematika yang terkandung dalam Al-Quran mengungkap strukturnya yang sangat indah melalui berbagai cara penyampaian yang salah satunya adalah kisah. Al-Kahf merupakan salah satu surat yang banyak menceritakan kisah-kisah terdahulu. Surat ini cenderung menyebutkan bilangan yang merupakan konsep matematika melalui pemaparan kisahnya oleh penceramah. Fokus penelitian ini mengungkap konsep matematika yang terdapat dalam surat Al-Kahf. Dimana Penelitian ini dilakukan dengan mengkaji secara kepustakaan dari berbagai sumber cetak dan digital terkait konsep matematika dalam Al-Kahf. Hasilnya ditemukan sebanyak 29 ayat berbicara tentang konsep matematika. Konsep ini diungkapkan secara langsung dan melalui tafsiran. Dari 29 ayat tersebut kemudian diklasifikasikan menjadi lima aspek umum dalam matematika yaitu himpunan, bilangan, geometri, logika dan statistika.

Abstract

One factor that is often happened is the learning objectives are difficult to achieve, because students often make mistakes in understanding the concepts and performing calculations. One way that teachers can do to minimize these errors is to classify between students who have been able to master the material and students who have not been able to master the material. Discriminant analysis is one way to facilitate the grouping of students according to their ability to master the material, by using the method of Fisher. The purpose of this study was determining how the percentage of students who have mastered the material prism and pyramid, getting the discriminant function of the prism and pyramid mastery of the material, and determining the factors that cause students difficult to understand the material prism and pyramid. The study population was the entire eighth grade students of SMP Negeri 1 Banda Aceh while the sample were students of class VIII-8 to 30 students. Based on the research that has been done using the fisher discriminant analysis method, 33.3% of students have mastered the material geometry and 66.6% of students have not mastered the material prism and pyramid. It means that from 30 students only 10 students were able to master the material well-prism and pyramid. End function that is formed is Y1 = 5,487X1 + 3,373X2 - 4,822X3 + 5,936X4 + 1,544X5 - 2,108X6 and Y2 = 5,486X1 + 3,373X2 - 4,823X3 + 5,937X4 + 1,544X5 - 2,107X6.

Abstract

Saat ini obesitas telah menjadi endemik global, dimana prevalensi obesitas tidak hanya meningkat pada usia dewasa namun juga pada usia anak hingga remaja. Obesitas terjadi jika ada energi yang masuk lebih besar daripada energi yang keluar. Energi sisa ini akan dideposit sebagai jaringan adiposa, sehingga terjadilah kenaikan berat badan yang salah satunya disebabkan oleh makanan siap saji. Makanan siap saji atau cepat saji adalah makanan yang tidak seimbang gizinya. Tujuan penelitian ini adalah untuk mengetahui pengaruh konsumsi makanan cepat saji terhadap peningkatan obesitas pada anak usia pra-remaja (10-12 tahun) di Banda Aceh. Penelitian ini menggunakan jenis penelitian studi pustaka dan data yang diambil berasal dari skripsi seorang mahasiswa sarjana Fakultas Kedokteran Unsyiah yang berkaitan dengan Makanan cepat saji dan tingkat obesitas pada anak pra-remaja di Banda Aceh. Pelaksanaan penelitian ini menggunakan bantuan software SPSS dalam mengelompokkan data variabel-variabel kedalam kategori obesitas dan tidak obesitas dengan metode Fisher. Adapun fungsi diskriminan dalam penelitian ini ada dua fungsi, yaitu untuk yang obesitas : 1,378x1 + 1,100x2 + (-4,234)x3 + 1,638x4 + 1,111x5 + 22,649x6 + 5,643x7 + 1,321x8 + 0,793x9 + 5,357x10 = 0. Dan untuk yang tidak obesitas :3,424x1 + 1,213x2 + (-5,536)x3 + 2,818x4 + 1,014x5 + 16,792x6 + 5,832x7 + 1,218x8 + 0,557x9 + 5,469x10 = 0.

Abstract

The Minimum Competency Assessment (MCA) is one of the components of the National Assessment (NA) in Indonesia, which aims to measure students' cognitive abilities, including numeracy skills. Students with low numeracy skills can be affected by not being used to working on MCA-type problems. This study aims to develop MCA items on algebra that meet valid, practical, and effective criteria using the Tessmer model, including preliminary, self-evaluation, expert reviews, one-to-one, small group, and field test stages. The subjects in this study were 36 Year 7 students of one junior high school in Banda Aceh, Indonesia. The instruments used were validation sheets, practicality sheets, and student response problemnaires. The findings indicated that 15 MCA problems on algebra have met the validity, practicality, and effectiveness criteria. It shows teachers can use MCA items to train students' numeracy skills. Future researchers are expected to develop multiple problems within a single stimulus with more varied content and context; they will need to consider the novelty of the stimulus in real conditions in the field.
