Abstract

Setiap pelaku usaha pasti menghadapi tantangan untuk mengoptimalkan keuntungan dengan sumber daya terbatas, terutama dalam menentukan jumlah produksi yang sesuai permintaan. Penelitian ini bertujuan untuk mengoptimalkan keuntungan penjualan gorengan pada usaha kecil di lingkungan perumahan Pagutan Barat, yang berfokus pada dua produk utama yaitu tempe goreng dan tahu isi. Proses optimalisasi menggunakan metode Simpleks dengan bantuan software POM-QM. Metode Simpleks dipilih karena mampu menentukan kombinasi produksi optimal dengan mempertimbangkan batasan sumber daya dan target keuntungan. Berdasarkan hasil perhitungan optimasi, diperoleh bahwa jumlah penjualan harian supaya mendapatkan keuntungan paling optimal adalah 30 pcs tempe goreng dan 90 pcs tahu isi. Penerapan metode ini menghasilkan keuntungan penjualan sebesar Rp. 90.000 per hari. Hal ini tentunya memberikan dampak positif pada total keuntungan usaha. Hasil ini membuktikan bahwa metode Simpleks mampu membantu pelaku usaha memperoleh keuntungan yang lebih optimal. Penelitian ini menunjukkan bahwa penerapan teknik optimasi matematis dapat menjadi solusi praktis bagi pelaku usaha dalam mengelola dan mengoptimalkan penjualan.

Abstract

Rumah Kaos convection is a manufacturing company that focuses on producing high-quality t-shirts with a variety of design options. This research aims to optimize turnover from t-shirt production by applying a linear programming approach using the simplex method. The data analyzed includes product type, raw materials, working time and selling price. The analysis process is carried out by compiling objective functions, constraint functions, and simplex table modeling. The results of this research show the optimal combination in raw material allocation that can maximize profits. It is hoped that these findings will serve as a strategic guide for entrepreneurs in planning production efficiently and achieving sustainable business growth.

Abstract

Food stalls are one form of culinary business that faces challenges in managing limited raw materials to maximize profits. This study uses a linear programming method with a Simplex approach to optimize the profits of Solo food stalls that sell three main menus: fried rice, fried noodles, and meatballs. The optimization model is designed by considering the limitations of raw materials such as vegetables, eggs, chicken, oil, sauce, and spices, as well as the selling price and cost of raw materials per portion. In this case, we use manual and software analysis, namely by using POM-QM for Windows. The results of manual and software analysis show the same results, namely by producing 25 additional packages of fried rice and 33.33 packages of meatballs. Because the requested results use integer numbers, we perform branch and bound analysis to produce the maximum value with all values ????of x1, x2, x3 are decimal numbers. The optimization results show that the Simplex method can determine the combination of the number of portions of each menu optimally to achieve maximum profit without violating resource constraints. Thus, this article was created so that we can determine the maximum profit with the availability of existing raw materials and with the capacity that traders have to make it easier for traders to manage.
