Abstract

This study investigates the influence of price and product quality on consumer purchasing decisions for local rice, utilizing a case study approach and multiple linear regression analysis. The objectives are to determine (1) the partial impact of price and product quality, (2) the extent of their individual influence, and (3) the combined effect of these variables. The findings reveal that both price and product quality significantly and positively affect consumers’ decision-making, both when evaluated independently and jointly. The coefficient of determination (R²) is 0.375, indicating that 37.5% of the variation in consumer decisions can be explained by the combined influence of price and product quality. This highlights the relevance of economic and qualitative factors in shaping consumer behavior, suggesting that improvements in either attribute could enhance market competitiveness for local rice. Overall, the results emphasize the strategic importance of understanding and leveraging pricing and product standards in agricultural marketing efforts.

Abstract

This study investigates the technical and economic aspects of Plant Growth-Promoting Rhizobacteria (PGPR) production at CV. Banua Sejahtera Lestari in Danau Karya Village. Using a case study approach, the analysis covers production methods, cost structure, profitability, and operational challenges. PGPR production follows strict Standard Operating Procedures (SOP), utilizing laboratory-grade equipment in hygienic conditions under supervision by qualified personnel. Each cycle spans 15 days and is repeated twice monthly, yielding 200 liters per cycle. The production cost per cycle is IDR 2,600,000, while revenue reaches IDR 4,000,000, resulting in a net profit of IDR 1,400,000. The Return Cost Ratio (RCR) of 1.53 indicates economic feasibility and a favorable return on investment. Challenges include maintaining consistent product quality and managing production risks. Overall, PGPR production at CV. Banua Sejahtera Lestari demonstrates strong potential for sustainable agribusiness development in Barito Kuala Regency.
