Impact of Land Size, Selling Price, and Production Expenses on Sales Volume in Red Brick Home Industries within Klangenan District: Lessons for Business Education

This research examined the influence of land area, selling price, and production costs on the sales volume of red brick home industries in Klangenan District. Using multiple linear regression analysis with data processed through SPSS 26, the study evaluates both partial and simultaneous effects of the independent variables. The results indicate that simultaneously, land area, selling price, and production costs significantly affect sales volume. Partially, land area has a positive and significant influence, while selling price demonstrates a negative and significant influence on sales volume. In contrast, production costs do not show a significant effect. The coefficient of determination (R²) reveals that the three independent variables collectively explain 5.3% of the variation in sales volume, with the remaining 94.7% influenced by factors outside the model, such as product quality, market demand, competition, and other external conditions. These findings suggest that land utilization and pricing strategies are critical for sustaining competitiveness, while cost efficiency alone does not directly drive sales performance.
