Abstract

The purpose of this study is to develop a decision support system to support supplier selection process in PT Guna Elektro and also to develop a system that could provide alternatives to the selection of the best suppliers. The methodologies used in this study are analysis, design, and literature study. Analysis will be done by conducting a survey about the current company system, conducting interviews with system users, and then analyzing the survey results. The literature study is conducted by searching reference sources related to the study while the design is conducted by designing a data management subsystem, model, knowledge base, and user interface. The result on the development of the decision support system application can be used to select the most appropriate supplier which are suitable with the criteria required. The developed decision support system helps support the decision making process for supplier selection.

Abstract

Cell phones are now a cheap means of wide-ranged wireless communication. One feature widely used is the short message service (SMS). The cellular communication system is more appropriate for long-distanced applications than high speed data transfer. This study aims to develop a GSM modem interface with AVR microcontroller using C programming language. The tools controlled by the microcontroller system can gain more benefit if it is linked with GSM mobile communication system. The results of this study can be applied whether in a remote monitoring system, remote control system, or communication between the microcontroller via SMS. Many additional benefits can be obtained for the tools controlled by the microcontroller when connected to a GSM system.
