Small and medium scale industries that are newly developed have many obstacles due to their ability and experience compared to other large industries. Plastic bowls for collecting rubber latex is one of the products that made from the injection moulding process. The company wants to improve its competitiveness by reducing raw materials used along with considering the quality of the products produced, but due to lack of information, this process is carried out trial & error. This study aims to determine the combination of parameters that can minimize the net weight of the product but still meet the product strength standards, the method used in this study is general factorial design because this method can investigate the effect of each factor and its interactions as additional information. In the analysis of variance (Anova), the temperature barrel in this study is a factor that has a contribution of 88.41% and 90.66% for the net weight and tensile strength of the product. The optimum conditions for this product are A3B1C1D1 by using the regression equation, the net weight of product is 17.3gr with product tensile strength 938,285N.
