Abstract

SMAS Setia Budi is a private school in Sungailiat that wants to improve the quality of its educational services by using information technology systems. In carrying out its business processes, schools have not maximized the information system architecture in accordance with the needs of school business processes. Researchers found several problems that occurred in schools such as in terms of new student data collection, administrative and financial processes, problems with procurement of goods, and others. To help plan the development of information systems at SMAS Setia Budi, researchers designed a business architecture (enterprise architecture) using the TOGAF framework with the (ADM) method as a problem solving. In this study, an analysis of each phase in TOGAF was carried out, namely preliminary phase, vision architecture phase, business architecture phase, information systems architecture phase, technology architecture phase, and opportunities and solutions phase. The purpose this study is to recommend blueprints, namely five application blueprint consisting of Academic Systems, Non-Academic Systems, School Procurement Management, School Financial Management, and School Data Management. Design is expected to be a benchmark for the development of information systems at the SMAS Setia Budi school and assist the school in carrying business processes in schools to be effective.

Abstract

Rural areas that may still be difficult to get 4G signals are caused by the diversetopography of the region and uneven landscapes, especially in mountainous areaswhich result in weakness in signal reception in the area. To get 4G signal coveragein this area, it is necessary to have a repeater in the form of an antenna thatfunctions as a signal booster in the area. In this study, a helix antenna consistingof ten windings at the uplink (1710-1785 Mhz) and downlink (1805-1880 Mhz)4G LTE frequencies was designed. It is hoped that this antenna can produce highergain and a more focused beam, with the aim of strengthening 4G signals in ruralareas. The antenna design was tested through the use of CST Studio Suitesoftware. The antenna design has been simulated using CST Studio Suitesoftware. After optimizing the simulation results, a return loss of -14 dB, VSWRof 1.49, a gain of 12.47 dBi, and HPBW of 500 were obtained. From themeasurement results obtained, the helix antenna with ten turns shows goodperformance at a frequency of 1880 Mhz with a return loss of -17.75 dB, VSWRof 1.32, gain of 12.15 dBi, HPBW of 440, and unidirectional polarization.
