Abstract

Usaha Kecil dan Menengah (UKM) memiliki potensi yang cukup besar untuk dikembangkan, Kota Serang sebagai ibu kota provinsi Banten menjadi salah satu tempat yang strategis dalam mengembangkan Usaha Kecil dan Menengah, tercatat pada tahun 2018 terdapat 10.321 Usaha Kecil dan Menengah di Kota Serang. Angka tersebut membuktikan bahwa banyak sekali pelaku UKM di Kota Serang, salah satunya usaha kuliner yaitu Seblak Gaul Bpk. Pitra. Pengelolaan yang kurang baik dan perencanaan jumlah produksi yang belum optimal berdampak pada keuntungan yang diperoleh tidak maksimal dan sulit di prediksi. Perumusan masalah dalam penelitian ini adalah : "Maksimalisasi keuntungan pada UKM seblak Gaul BPK. Pitra di kota Serang menggunakan linear programming melalui metode simplek" . linear programming melalui metode simplek adalah metode yang tepat digunakan untuk mementukan jumlah produksi produk makanan agar keuntungan maksimal. Hasil penelitian diperoleh bahwa Jumlah produksi seblak mie dan seblak telur sebanyak 3 porsi, dengan keuntungan maksimal RP.750.000.00

Abstract

This study examines how algebra block support and the Numbered Head Together (NHT) learning paradigm affect secondary school students' mathematical creativity and self-efficacy. The literature review highlights the necessity of creative teaching strategies in mathematics education. In this study, a non-equivalent control group was utilized in a controlled experimental design, with one group implementing the NHT model with algebra block support and another group employing traditional teaching techniques. Pretest, posttest, and self-efficacy instruments were used to gather data. The study's results indicated a significant increase in students' mathematical creativity capacity when utilizing algebra blocks to support the NHT model. In addition, there was a noticeable increase in the pupils' self-efficacy. An examination of the data using statistical methods revealed notable distinctions between the experimental and control groups. The primary finding indicates that the NHT learning paradigm, in conjunction with algebra blocks, helps enhance secondary school students' mathematical creativity and self-efficacy capacity. The study's findings offer insightful information about initiatives to enhance methods for teaching mathematics.
