As As the automotive world in Indonesia has progressed, car vehicles are starting become a hobby item, car hobbyists consider their car is a life partner and want their car always in the best condition in terms of engine, interior, and exterior. In maintaining the condition of the interior and exterior, one solution is to use car detailing services, Java Detailing Workshop is a workshop that provides car detailing services to make the interior and exterior conditions return to prime after only being used for a while. As the number of car hobbyists in the Jabodetabek area grows, the workshop cannot meet the increasing demand for car detailing services every month so currently the company uses a reservation system and customers have to wait until the customer can be served after the customer has completed the reservation. To solve this problem, this research was made using the MEPIS productivity cycle method so that companies can increase their productivity in a sustainable manner assisted by an Objective Matrix to measure productivity and assisted by Fishbone Diagrams in conducting evaluations. It was found that the factors that affect productivity are the energy use and working time of each car, the improvements made in the fields of humans, machines, methods, and the environment with the results of electricity usage efficiency of 28% and car detailing time efficiency of 6% which can add service capacity one car per month.
