This study provides an in-depth analysis of the benefits of implementing a SAP-based Enterprise Resource Planning (ERP) system for end-users at PT XY, an Indonesian airport management company. A qualitative case study approach was applied through comprehensive in-depth interviews and direct observations of accounting division staff who actively utilize the SAP Financial Accounting (FI), Controlling (CO), and Materials Management (MM) modules as part of their daily operations. The findings demonstrate that SAP implementation significantly enhances work efficiency, data accuracy, and overall operational productivity across multiple business processes. The system facilitates seamless cross-departmental integration, reduces manual errors, accelerates financial reporting, and supports real-time, data-driven decision-making. Furthermore, SAP strengthens internal coordination by providing consistent, centralized, and easily accessible information to all relevant stakeholders. Key challenges identified include limited network access, server congestion during peak hours, and difficulties with remote connections when accessing the system outside the office environment. The company addressed these issues through regular user training, provision of secure Virtual Private Network (VPN) access, expansion of server capacity, and a strategic plan to migrate to cloud-based SAP S/4HANA to improve flexibility, scalability, and long-term system reliability. The findings not only enrich the literature on ERP adoption, with practical guidance for other organizations seeking to plan, implement, and evaluate ERP systems to meet their own business needs, including effective human resource planning and change management strategies.

The increasing vulnerabilities of modern enterprise network security systems highlight the necessity of adopting a more comprehensive and adaptive security approach than traditional VPN infrastructures. This study explores the design and implementation of Zero Trust Network Access (ZTNA) using the Cloudflare platform at PT FHI, focusing on addressing the weaknesses caused by uncontrolled remote access and legacy security models. The research adopts an experimental methodology based on the Network Development Life Cycle (NDLC), which includes systematic phases such as needs analysis, architectural design, system implementation, testing, and performance evaluation. Data were collected through structured interviews with IT managers and security specialists, direct observation of network logs, and comprehensive testing involving three different categories of end users. The findings demonstrate significant improvements in role-based access control, granular authentication, and the elimination of unrestricted access to internal resources. Additionally, real-time monitoring and alerting features available through the Cloudflare dashboard enhance visibility and responsiveness to potential threats. The implemented system successfully applies the “never trust, always verify” principle by blocking unauthorized access attempts, enforcing continuous validation, and producing detailed audit logs. Performance evaluation results confirm stable connections, acceptable latency for critical business applications, and an overall improvement in network security posture while maintaining operational productivity across departments..

Android is an operating system whose capabilities continue to increase from year to year. The capabilities of Android currently match the capabilities of a computer. Not only limited to ordinary computers, what a server computer can do can now be done on Android, including making Android a web server. So it is possible for people who have Android to have their own web server. The problem that arises is that the web server on Android cannot be accessed directly via the internet. Cellular operators do not provide Public IP to their customers, so a way is needed so that the Android web server can be accessed on the internet, one of which is by using Virtual Private Network (VPN) technology. The aim of this research is to make the web server on Android accessible on the internet. The method used is to combine a Virtual Private Server (VPS) and Android using VPN. The research results showed that VPN can be a bridge so that the web server on Android can be accessed from the internet.

Building a computer network needs significant care in selecting a configuration to ensure its efficacy and efficiency. It involves decisions about network topology, types, and device use. Security measures are essential for protecting networks with internet access from external attacks. A study conducted at an Islamic university in Indonesia indicated the use of a star network architecture and a client-server network model. The servers utilize Debian Linux. The university's security infrastructure includes a server authentication system and the setting up of a Virtual Private Network (VPN). If the server authentication difficulty is caused by a power outage, it is recommended that you use an UPS (uninterruptible power supply) to preserve power stability. Overall, security methods show up to be more effective when firewalls are installed.

The development of science and technology in various fields in the era of globalization is felt to be very advanced. So that information is something that is needed in a fast, precise and accurate. Many conveniences are promised in a variety of information technologies. There is one fact that cannot be denied that this information has become an expensive commodity, if a company or agency cannot uphold the information that it needs most, then the procurement of information itself will obviously drain resources and funds. In doing business, PD. BPR BKK Demak Kota already has and uses an adequate accounting, deposit and credit information system. One of the strategies applied by PD. BPR BKK Demak Kota in collecting funds is the Ball Pick Up System, which is by visiting individual and institutional customers. While the institutions that have been served by PD. BPR BKK Demak Kota are schools, one of which is SMA Negeri 3 Demak. The service is in the form of an education fee payment. In serving the payment of school education costs in SMA 3 Demak, PD. BPR BKK Demak Kota still uses the conventional way, that is by receiving deposits from students, the data is recorded in the admission book and after adding up with a calculator, the result is that service is very slow. To overcome the problems mentioned above, it is necessary to build a system that can accelerate the process of receiving tuition fee payments and can produce a more detailed report on school fees both those who have paid and those who have not yet paid. One such system is utilizing VPN (Virtual Private Notwork) technology. Based on the description of the problem above, it becomes an impetus for the writer to be able to solve this system as well as possible and is very background for the writing of the Thesis which is planned to be realized using the Microsoft Visual Basic 6.0 program language
