Abstract

To take the employees? absences in a company, a variety of invented tools or technologies are and already used, for example, attendance cards, fingerprints attendance tool, and attendance tool that uses facial recognition. Attendance tool with a facial recognition uses iris recognition of those employees. Iris code has many properties that hard to forge. Thus, the detection and iris recognition is one of the most secure and accurate for identification.

Abstract

Japan currently has been successful to provide housing for low to high-income people in urban areas. Almost everyone in Japan can access their homes, either public housing or private one, depending on the level of their welfare status. The study discusses about development of public housing in Japan and why the Japanese people can accept the design of the vertical housing built by their government. The study is conducted with descriptive approach through literature study and field observations in the city of Tokyo and its surrounding areas to provide knowledge about the development of public housing in Japan started from traditional residential and then developed into a modern residential horizontally and vertically according to the needs of his hometown community. Despite of the development from time to time, the design of residence still considers the local culture of Japan. So the Japanese people can receive residential design, although it is developed into vertical housing. This study is expected to give inputs for the Indonesian government as an effort to achieve the successful provision of public housing in Indonesia.

Abstract

July 11, 2012 was chosen as an appropriate day in constitution terms to hold the election of Jakarta?s regional head for the next five years. There are many assumptions and opinions from some people about who would be elected as the governor of Jakarta. A lot of criteria from the candidates of governor and vice governor can be the parameters to be the success key in becoming Jakarta?s number one man. This research is discussing about decision making methods from many options by using AHP (analytical hierarchy process) method. Tthe case model is the election of Jakarta?s governor. The research utilizes two comparative components namely Jakarta?s governor and candidate of vice governor, as well as five criteria such as issues about  flood, transportation, economic, public services and credibility. The result of this research is the candidate with number six that should be most chosen in the election.

Abstract

Graphic Computers are widely used in various fields, especially in industries, companies, banks and hospitals. At hospital, computer graphics with leading edge techniques support images related to patient's needs. Graphic computer can also be used for shipbuilding and automotive design, as well as decision-makers in an institution, using pictures or images that can be analyzed to produce good forms which the accuracy is still investigated (CAD and CAM). The purpose of research is linking algorithms by creating the right picture or image to a form required by decision makers to associate algorithms Hermite, Bezier, B-Spline in harmonious function of each, so that the curves, images or images are produced better, and can be used in the field of engineering drawings. This research produces an image/ shape/ image which are suitable for designers? need.

Abstract

Designing car audio that fits user?s needs is a fun activity. However, the design often consumes more time and costly since it should be consulted to the experts several times. For easy access to information in designing a car audio system as well as error prevention, an car audio system based on expert system and web is designed for those who do not have sufficient time and expense to consult directly to experts. This system consists of tutorial modules designed using the HyperText Preprocessor (PHP) and MySQL as database. This car audio system design is evaluated uses black box testing method which focuses on the functional needs of the application. Tests are performed by providing inputs and produce outputs corresponding to the function of each module. The test results prove the correspondence between input and output, which means that the program meet the initial goals of the design.

Abstract

Bombings occurred in Indonesia mostly attack high-rise buildings. This fact should be a consideration for the structural engineer when designing high-rise building structures since the design of the structure does not include bomb blast burden in the calculation. This article discusses the dynamic response of buildings with of two plate stiffeners which are then given blast loads. The purpose of this study is to determine the effects of damping and the boom duration of the dynamic response of the plate. The plate is modeled damped orthotropic rectangular with semirigid placement on all sides. A decrease in plate element equilibrium equation is based on moment balance and forces on the plate. Meanwhile, the plate motion equations are derived using Newton's second law. The natural frequency of the plate system is obtained using the Modified Bolotin Method (MBM) as the numerical calculation process is completed with Microsoft Excel 2003 and Mathematica 5.2. Plates will be given damps as much as 0%, 5% and 10%. Each plate with each damp will be given blast loads for 1 ms, 2 ms, 10 ms and 20 ms. The research results shows that the greater the damp is used, the smaller system dynamic response will be. The longer the blast load works, the greater system dynamic response will be.

Abstract

Credit sales in a company have greater risks than cash sales do. An excellent internal control is needed over the accounting system of credit sales, receivables and cash receipts to reduce the occurrence of these risks. This study aims to evaluate, identify weaknesses and limitations of internal control and suggests some improvements as needed. The methods used are literary study on books, textbook, and other related literatures; field research by interviewing the relevant parts and observing the company activities, forms and accounting records used.

Abstract

Technology is one important factor that supports accuracy result of a disease in health. Along with technology, one?s knowledge could be broadening so he can make one exact decision about specific disease to get maximal result. Based on above considerations, it is designed a supporting decision-making system based on entered data, processed using weighting in AHP to know the result. The programming language is using PHP and the database using MySQL. The designing result could help doctors to choose specific medicine for the patients and help them to find information about cardiac failure and what stages to be done to help the patients healing.
