CV Indotani offers 67 agricultural chemical products, including fungicides,insecticides, bactericides, and nematicides. Some of these products can be used formultiple plant diseases, requiring consumers to consider various factors beforemaking a purchase decision. This process is often inefficient and time-consuming.Therefore, a system is needed to help consumers make purchasing decisions morequickly and accurately.This research aims to develop a web-based decision support system usingthe Simple Additive Weighting (SAW) method. The SAW method was chosenbecause it can provide clear and easily understood evaluations of various productalternatives based on predetermined criteria and weights.The methodology used in this research includes identifying systemrequirements, design, implementation, and testing. With the SAW method, farmersor consumers can input the desired criteria and weights, and the system willrecommend the most suitable products based on SAW calculations.The result of this research is a web-based decision support system that helpsfarmers or consumers choose the right agricultural chemical products moreefficiently and accurately. This system is expected to improve the effectiveness andefficiency of the purchasing decision process for agricultural chemicals at CVIndotani.
