Abstract

This study aims to optimize production using linear programming with graphical and simplex methods accompanied by sensitivity analysis to determine the optimal product combination with maximum profit for the "Bawang Goreng Crispy Yuk Riris". The data are sales, inventory, use of raw and additional materials, operations, and selling prices. The data analysis technique uses linear programming, graphs and simplex methods, and sensitivity analysis with the help of QM for Windows. The result shows that production optimization using linear programming graphical methods or simple graphs obtains the same results as the optimal solution of producing 713 packs of original crispy fried shallot and 333 packs of spicy fried shallot with a maximum profit of IDR 3.304.500.Sensitivity analysis shows that the solution remains optimal with the tolerance limit for the original taste from 0 to 3.500 and the spicy taste from 3.000 to infinity, and five production inputs are not optimal.

Abstract

This study attempts to map the business models of construction service SMEs to recommend new business model formulations that are relevant to the company's needs and challenges. This research maps the existing business models of companies, then analyzes their environmental conditions so that relevant strategies can be recommended and are expected to contribute to business development. This research was conducted using descriptive analysis, mapping the company's business model using the Business Model Canvas (BMC) approach and a SWOT analysis. A cross-analysis used to formulate a new business model. The study results show that companies need to offer value propositions that are difficult for competitors to replicate, rather than relying solely on low prices. Furthermore, companies are also required to leverage online promotions to reach a wider customer segment. Internal training and certification can be implemented to enhance service delivery and implement continuous improvement across the company. The company's customer base is still relatively young, so additional promotional efforts are needed to expand its market segment, including through social media. The new business model suggests the company should further improve the quality of its work through internal training, certification, and collaboration with relevant parties. This research offers new insights into the business models of construction service companies to develop and strengthen their presence in the industry. It is hoped that the formulation of this business model will provide stakeholders with diverse perspectives for policymaking and contribute to a more comprehensive literature.
