Abstract

This study aims to utilize the support vector regression (SVR) method as a machine learning technique to predict the selling price of laptops and their level of accuracy. Data collection is done through literature, internet and evaluation with MAPE. In this study the authors made the Laptop Price Prediction application using Pycharm with the Python programming language. The test results show that the calculation of the analysis performed by the application produces the same optimization value as the calculation done manually by the MAPE formula, which is 98%. This research was conducted on several online laptop sales webs, such as Tokopedia and Bukalapak. Laptop sales data are collected from online sales webs, used as a basis for experiments. Evaluation The results show that from testing 8 test data the best percentage of accuracy was obtained using MAPE, which is 74%.

Abstract

The aims of this study are to apply design patterns for developing library information system and analyze them from re-usability aspect. The applied design pattern consists of Factory Patterns and Façade Patterns. Factory Patterns are used to separate the process of making objects from other purchased objects. The Façade Patterns are used to reduce connectivity among classes and the complexity of the system being built. To evaluate the patterns, object-oriented metrics were used, both system that do not apply the design pattern and the proposed system (system that apply the design pattern). The results of the Object Oriented Metrics analysis using the Coupling Between Object parameter showed the decrease of the connectivity among classes so that the system is easy to reuse, in which the parameter Response for a Class (RFC) showed the reduction of the method in the class on a system that applied the design pattern which made it easier to be understood and tested. In addition, using the parameter Line of Code (LoC) showed the reduction of 228 lines code of program, from 4410 to 4182 so that the system made the program size smaller and the library information system become easier to be maintained, reused, and understood.

Abstract

The purpose of this study is to design an e-STNK prototype for payment of vehicle tax using RFID technology. Data collection was carried out through evaluation of prototypes developed by researchers and involving 20 respondents. After the evaluation is conducted, respondents are asked to answer the questions raised on the questionnaire and the results are used as a basis for drawing conclusions. In this study the authors made the e-STNK system to facilitate tax payments using RFID. The system consists of two major parts. The first part consists of the web server and MySQL database. The second part consists of the STNK card (e-STNK) in the form of RFID and the reader (RFID Reader). Server side is used by admin in processing e-STNK data. For its development, the authors use HTML, PHP programming language, and Javascript. While the RFID / STNK cards are used by users, which are developed using RFID devices, RFID readers, and Arduino microcontrollers. Development on the RFID system side uses the C / Arduino programming language. The results of the first evaluation, based on ISO 9126 testing, the prototype e-STNK runs as expected that the system is able to make tax payment transactions, store data transaction history of payment of taxes, a history of violations, and a history behind the name of the vehicle registration. While the second evaluation involving 20 respondents showed that all questions were given good responses except questions number 1.7 and 8 which were included in the good enough category.
