Difficulties in choosing a used car, a reference is needed as a rationale for choosing a used car. Decision support systems offer a solution for referrals in choosing a used car. Decision support systems offered using Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) in solving problems. Problems can be solved using a ranking system based on global weighting. Buyers of used car vehicles can choose used cars based on references or recommendations from expert decision support systems. Based on the results of the calculation of the assessment criteria proposed to the system, the determination of used cars is obtained through calculating the priority weight values for the selection of used cars to be purchased. With the Decision Support System to choose used cars using the Analytical Hierarchy Process (AHP) method and Simple Additive Weighting (SAW) in determining used cars the accuracy rate is 73% compared to using the Simple Additive Weighting (SAW) method which has a level of accuracy only 60%.

The objective is to assist prospective doctors, general practitioners and specialists in diagnosing disorders of the endocrine system like an expert, to provide information quickly, and to create an interactive application that can be easily understood by the users. The expert system is created using the Best-First Search method and using the Forward Chaining technique. The system contains the knowledge of an expert obtained during research at Permata Ibu Hospital and a knowledge base designed to be able to store new diseases. The expert system is developed based on smartphone technology or more specifically Android on the client side, PHP (Hypertext Preprocessor) and MySQL base on the server side. The system contains 6 disease data and 10 disease symptom data. It also has been tested and validated by experts and several users. The result reaching a percentage of 83.3% shows that the expert system application is quite efficient and effective.
