Abstract

The Point Of Sale (POS) business management system is an application program that can facilitate all trading processes, but this system can only be installed on low-spec computers with a fairly complicated installation process. Based on these problems, the authors try to find solutions on how to develop POS application programs into web programming so that they can be installed on all mainstream operating system products. The POS system developed is a management system that can manage several important functions in web-based business management using the PHP programming language with the Code Igniter 3 Framework, Apache web server and MySQL database. The research methodology used is an action research method with data collection techniques through interviews. The waterfall development model is designed using the UML design method, and tested using black box testing techniques. Through this development process, desktop-based POS application programs have been successfully developed into web programming and can be installed on mainstream operating system products such as Windows, Linux and Macintosh.

Abstract

The range of DC output voltage of the photovoltaic cell is about 20 - 45 Vdc. At generally electrical load use an AC voltage is about 220 Vac for one phase load and a 380 Vac for three phase load. So that the output voltage of the photovoltaic cell has to raise up to 400 Vdc and then it voltage changed to an AC voltage with an inverter. In this paper, the voltage conversion ratio of the DC to DC voltage with high gain cell power converter will be analyzed and simulated with PSIM software. From the analysis and simulations show that the output voltage of that converter can be achieved it about 400 Vdc from around input voltage 20 Vdc, the duty cycle of the semiconductor switch is 71 %.
