Abstract

Linear programming (LP) plays a significant role as an analytical tool in environments where decision-making must be conducted under resource constraints. As an optimization method, LP models problems by defining decision variables, objective functions, and constraints to identify the most efficient solutions within given limits. In managerial and operational contexts, LP assists in allocating scarce resources effectively to maximize outcomes such as profit or operational efficiency, enabling stakeholders to make objective, data-driven choices. Recent applications of LP span from business planning to decision support systems that optimize promotional strategies, demonstrating how structured mathematical models can guide complex decision processes. Moreover, LP is integrated into educational contexts to strengthen analytical reasoning, helping learners link theoretical formulations with practical economic choices. This article synthesizes findings from recent literature to illustrate how LP fosters systematic decision-making, enhances clarity in trade-offs between alternatives, and supports rational choices in constrained environments. The reviewed studies confirm that LP not only serves as a computational optimization technique but also reinforces structured thinking essential for decision quality when resources are limited. Hence, LP remains a valuable method for both practitioners and scholars in decision sciences.

Abstract

The tofu industry is a type off small and medium enterprise that requires optimal production management to maximize profits generated with limited resources.This study aims to optimize tofu production volume using a linear programming approach with the simplex method.The matematichal model developed in this study is in the form of an objective funcition ti maximize profits with limitations such as limited raw materials raw materials,labor,andlimited production capacity.The data used is tofu production data analyzed quantitatively. The model is solved using the simplex method to obtain an optimal solution.

Abstract

This study aims to determine the mathematical reprentation ability of students in class VIII MTs. Swasta Al-Ittihas Aek-Nabara. The research subjects were students of MTs. Swasta Al-Ittihas Aek-Nabara and the sample used amounted to 25 students. The method applied in this research is descriptive qualitative with tests and interviews as a research data collection technique. Data analysis techniques used in the study consisted of data reduction, data presentation and conclusion drawing. The results showed that the mathematical representation ability of class VIII students in the school on the material of the system of linear equations of two variables was in the low category
