- Motorcycle is a transportation with the most fans. Various types of motorcycle is used more, one of the motorcycle cub/moped. The underbone is one that is a favorite of the riders, especially men's riders. Some motor manufacturers such as Yamaha and Honda produces underbone, with a range of offerings and offered advantages from each manufacturer. It turned out to be one more attention from consumers, they started trouble choosing which underbone that best fits their criteria. In this case, the criteria taken into consideration, including the price, the use of fuel efficient, design body, and the dimensions of the motor frame. This needs to of a Decision Support System that could helped give any information and recommendations on underbone in accordance with criteria consumers. In the development of a decision support system there is one of the models that are commonly used, namely Fuzzy MADM (Multiple Attribute Decision Making). In this research will use one method problem solving of the model , that is simple additive weighting. This method was chosen because it can determine the best alternative of some alternatives so that in accordance with the criteria referred to. In this research will be carried out the calculation of the weighted alternative that will produce the best alternative, namely the underbone elected that could be a recommendation.

Praktek Kerja Industri (PRAKERIN) information system is a system used to record grades and other student data relating to the implementation of work practices in industry. This information system must be error free. If an error occurs can cause losses to stakeholders. To provide assurance that the information system developed has been free from errors, it is necessary to test. Testing is one level of the program implementation process that must be passed in order that an error can be found. Tests that can be said to be good are if the tests were initially found no errors and then errors can be found, even if only a small error. In testing the Praktek Kerja Industri (PRAKERIN) information system it is proposed as a Black Box. Black Box testing has various techniques. Of the many testing methods currently available, the current testing will use the Boundary Value Analysis method. The technique of determining the limits that exist in the lower and upper values to be able to produce the actual value. The test results show that the information system developed has been error free and has good quality.
