Excess or lack of nutrients contained in food will cause a problem in the body. To solve this problem easily, a computerized system is needed that can provide some advice on the amount and type of food that needed to be consumed. The aim of this study is to design an expert system which addresses individual diet based on calorie activities and body needs. This study uses the Prototype as a software development methodology and Data Flow Diagram (DFD) as a software model. This expert system uses a harmony search algorithm to determine the amount of food with Harris-Benedict formula to calculate the body’s calorie needs. The results of functional system testing and based on the assessment of nutritionists, this expert system have been worked well for people with normal body metabolism.

Teacher certification is a process of improving the quality and competency testing of educators regulated by the government through ministry of education. the education office, which it provides teacher certificates that have been declared to meet professional standards. It would not happen if the assessment is carried out using an effective method in selecting teacher certification participants. The purpose of this research is to make a decision support system by applying 2 methods, namely Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) methods.

Pathways admissions line independent achievement sports especially badminton was held in UIN Sunan Gunung Djati Bandung aimed to help athletes who want to proceed to a higher level and change the paradigm of athletes on the importance of continuing education to a higher level in accordance with the specified criteria. The process of input in determining the acceptance still uses old system by Microsoft Excel that sometimes causes confusion. To help determine an independent candidate of badminton accomplishment line, it is then required a decision support system. The Method that can be used for deciding support system by using Analytical Network Process (ANP). Using this method, the calculation was done by doing a comparison between the criteria and alternatives then produce supermatrics, then do the weighting process will determine the athletes who deserve to UIN Sunan Gunung Djati in Bandung. This research used 9 prospective registrants (alternate) as a sample after doing comparison calculation manually and the application of the method itself then acquired relative error of 0%. So the system has been made is said to be worth used relative error less than 50%.
