Evaluasi Infrastruktur Jaringan Komputer Menggunakan PPDIOO pada Badan Pendapatan Daerah Kabupaten Majalengka

Abstract

This study aims to evaluate the computer network infrastructure and formulate a redesign at the Regional Revenue Agency of Majalengka Regency to mitigate system failure risks due to reliance on a single internet service provider. The novelty of this research lies in the execution of the complete network development lifecycle, encompassing the preparation, planning, design, implementation, operation, and optimization phases. Given the critical nature  of  government  agency  operations  requiring  zero  downtime,  the  implementation, operation,  and  optimization  phases  were  fully  realized  within  a  virtual  simulation environment using Cisco Packet Tracer software. Evaluation results indicate that although the  existing  infrastructure  has  adequate  logical  network  segmentation  and  automated addressing, the absence of a backup connection line remains a primary vulnerability. As a solution, this study produces an architectural recommendation that integrates a secondary internet  service  provider  with  an  automated  connection  switching  configuration. Simulation  results  prove  that  the  proposed  design  successfully  maintains  smooth  data traffic  during  disruptions,  thereby  ensuring  the  continuous  availability  of  digital  tax services.
