Abstract

Business of buying and selling used cars in Indonesia is increasing and growing, so it demands a fast, precise and economical repair process. To increase the selling price of used cars, it is necessary to repair used cars or what is better known as refurbishment work pre-owned cars, which are mostly carried out by small-scale used car buying and selling businesses. This study aims to process of painting refurbishment work pre-owned cars a Toyota Avanza car bodypaint against the thickness of the paint using a spray booth tool by using the model of central composite design (CCD). The effect of spray-on booth temperature, interstice size of the spray gun, and time according to the thickness of the paint will be analyzed using the CCD method. This spray booth painting technology is expected to help reduce bodypaint lead time. The results of the ANOVA (Analysis of Variance) regression analysis, the temperature of the spray booth, interstice size of the spray gun, and time are the factors that most significantly affect the thickness of the paint. The operating conditions to produce optimal paint thickness is at temperature 55oC, interstice size of spray gun of 1.7 mm and time of painting and drying of 30 minutes, the resulted of a thickness of the paint for used and new cars are 130.2 μm and 81.84 μm., with a coefficient of determination for used and new cars of 90.78% and 96.19%.
