Abstract

Program linear adalah suatu model yang melibatkan fungsi-fungsi linear dan dapat digunakan dalam pemecahan masalah pengalokasian sumber-sumber terbatas secara optimal. Pokok pikiran menggunakan program linear adalah merumuskan masalah dari informasi yang tersedia, kemudian menerjemahkannya dalam bentuk model matematika. Penelitian ini bertujuan untuk membantu perusahaan hijab Syara mencari penyelesaian dalam memaksimumkan keuntungan produksi hijab dengan memodelkan masalah produksi hijab kedalam metode grafik dengan menggunakan alat bantu Microsoft Excel, dan menentukan kuantitas masing-masing jenis produksi dengan mengoptimalkan penggunaan bahan baku untuk menghasilkan keuntungan yang maksimal. Berdasarkan hasil penelitian, perusahaan Syara memperoleh keuntungan maksimal yaitu sebesar Rp. 6.685.000,00 per bulan dari hasil jumlah produksi pashmina dan hijab segi empat.

Abstract

Mathematical literacy ability is one of the abilities that students must have. Mathematical literacy ability includes the ability to understand, use, and apply mathematical concepts and procedures in various situations, both in academic contexts and in everyday life. This study aims to analyze the effect of the Realistic Mathematics Education (RME) Approach Assisted by the PLSV Board on mathematical literacy ability. This research was conducted at one of the junior high schools in Tangerang City in the odd semester of the 2024/2025 academic year. This study used a quasi-experimental method with a randomized posttest only control design involving 30 students in the experimental group and 32 students in the control group. Data collection on mathematical literacy ability used a test instrument in the form of seven descriptive questions that had been tested for validity, reliability, discriminatory power and level of difficulty first. The indicators of mathematical literacy ability studied were formulate, employ and interpret. The results of the study showed that the mathematical literacy skills of students in the experimental class whose learning used the Realistic Mathematics Education (RME) Approach Assisted by the PLSV Board were higher than those in the control class whose learning used the scientific approach.
