Abstract

Low motivation to learn is often a serious challenge in one's academic development. Excessive use of social media can have both positive and negative impacts on learning motivation, depending on the usage policy. This study aims to analyze the magnitude of the relationship between the use of social media and the motivation to learn mathematics of class VIII students of SMP Negeri 6 Percut Sei Tuan. This study uses a quantitative approach with a correlational method. The sample consisted of 58 grade VIII students who were given video supplements related to learning materials at school through TikTok before formal learning was carried out. Based on the data analysis used using the Spearman correlation, the correlation coefficient value is + 0.744, it can be seen that the motivation to learn mathematics with the use of social media has a unidirectional relationship. This shows that if there is an increase in the value of using social media in learning, the value of math learning motivation will also increase linearly. By treating relevant learning videos through TikTok social media before learning takes place, educators are able to create a more interesting and intimate learning experience to increase student motivation in learning mathematics.

Abstract

Ketahanan pangan merupakan kondisi di mana setiap orang memiliki akses terhadap pangan yang cukup, aman, dan bergizi. Penelitian ini bertujuan untuk menganalisis aplikasi dan penerapan matematika, khususnya fungsi penawaran dan permintaan, dalam konteks ketahanan pangan. Metode yang digunakan adalah analisis deskriptif eksploratif dengan mengumpulkan data melalui studi literatur. Fungsi permintaan pangan menggambarkan hubungan antara jumlah pangan yang diminta dengan faktor-faktor seperti harga, pendapatan, selera, dan jumlah populasi. Sementara fungsi penawaran pangan menggambarkan hubungan antara jumlah pangan yang diproduksi dengan faktor-faktor seperti harga, biaya produksi, teknologi pertanian, dan kondisi geografis. Keseimbangan pasar terjadi ketika jumlah pangan yang ditawarkan sama dengan jumlah pangan yang diminta. Perubahan pada faktor-faktor yang mempengaruhi penawaran dan permintaan akan berdampak pada ketahanan pangan. Pemerintah memiliki peran penting melalui kebijakan produksi pangan, harga dan pasar, distribusi, pendapatan dan perlindungan sosial, lingkungan dan perubahan iklim, serta koordinasi dan kemitraan. Hasil penelitian menunjukkan bahwa pemahaman terhadap fungsi permintaan dan penawaran pangan serta faktor-faktor yang mempengaruhinya dapat membantu dalam merancang strategi yang efektif untuk meningkatkan ketahanan pangan secara berkelanjutan.

Abstract

This research examines the influence of the existence of zoned schools on equal access to education in Malang district. The problems in this research are the pros and cons of school principals, teachers, parents and students regarding the school zoning system in Malang district. Based on research conducted by researchers, many school principals, teachers, parents and students do not agree with the existence of a school zoning system. Because students who excel and are competent do not get favorite schools to support their long-term careers. On the other hand, from the teacher side, teachers are very depressed and stressed because they find so few talented and high-quality students in the learning process at school. This research uses qualitative methods in the form of interviews with school principals, teachers, parents and students in the school environment. The research results prove that in the absence of an educational zoning system in Indonesia, you will find many students who excel and excel in elementary, middle and high school. Because with the student zoning system there tends to be no competition between students and other students. However, this has led to a decline in the quality of education in Indonesia through the school zoning system.
