Abstract

The Integrated Statistical Service (PST) at BPS East Lampung Regency handles a high volume of data requests from researchers, government agencies, students, and private institutions through its front-line channel, TANGKIS. This service currently relies on walk-in visits, manual logbook recording, and unstructured WhatsApp or email correspondence, causing delayed processing, inconsistent follow-up, difficult status tracking, and the absence of formal notification when requested data is ready. This study aims to design and develop a web-based TANGKIS information system with an automatic email notification feature to digitize and streamline the request workflow. The system was developed using the SDLC Waterfall model, with UML-based design, PHP and Laravel implementation, a MySQL database, and PHPMailer integrated with SMTP, then evaluated through Black Box Testing and a dedicated notification reliability assessment. Black Box Testing of 20 functional features achieved 100% validity, while 30 simulated requests reached a 100% email delivery rate with an average latency of 4.8 seconds, reducing data-readiness awareness time from one to three days to under one minute. These results imply that a low-cost, event-driven email notification architecture can meaningfully strengthen the efficiency, transparency, and responsiveness of statistical public service, supporting the digital transformation of regional government statistical services.

Abstract

Student attendance recording at MTs Wasilatul Huda Sukadana, East Lampung, is currently managed manually using paper-based attendance books, resulting in delayed attendance recapitulation, the risk of document loss, and the absence of real-time communication with parents. Consequently, parents often remain unaware of their children's attendance status until the end of the semester, reducing opportunities for timely intervention. This study aims to develop an Android-based student attendance information system integrated with real-time parental notifications. The system was developed using the Software Development Life Cycle (SDLC) with the Waterfall model, including requirements analysis, UML-based system design, implementation using Flutter, Laravel RESTful API, MySQL, and Firebase Cloud Messaging (FCM), followed by Black Box Testing. The developed application enables teachers to record attendance through manual input or QR-code scanning, while parents instantly receive notifications containing attendance status, recording time, and remarks. Testing of 24 functional features achieved a 100% validity rate. Notification performance evaluation across 50 simulated attendance events showed a 100% delivery success rate with an average latency of 2.3 seconds. The average time for parents to receive attendance information decreased from several hours to less than five seconds. The study concludes that the system significantly enhances the timeliness, accuracy, and transparency of attendance communication between schools and parents, while supporting more effective monitoring of student attendance.

Abstract

The management of incoming and outgoing official correspondence at the Regional Finance and Asset Agency (BPKAD) of East Lampung Regency is still carried out conventionally, in which letters are recorded manually in a logbook, physically distributed between divisions, and archived in paper-based filing cabinets. This practice has led to delays in letter disposition, frequent loss or misplacement of physical documents, difficulty in tracking letter status, and inefficiency in the archiving and retrieval process. This study aims to design and implement a web-based electronic correspondence information system to digitize the administration of incoming and outgoing letters at BPKAD East Lampung Regency. The system was developed using the Software Development Life Cycle (SDLC) with the Waterfall model, consisting of requirements analysis, system design using Unified Modeling Language (UML), implementation using the PHP programming language with the Laravel framework and a MySQL database, and testing using the Black Box Testing method. The results show that the developed system is able to digitize the letter disposition workflow, provide real-time tracking of letter status, generate an automatic letter numbering mechanism, and produce a centralized digital archive that can be accessed based on user authorization levels. Black Box Testing on 15 functional features showed a 100% valid result, while a System Usability Scale (SUS) evaluation involving 20 respondents yielded an average score of 81.4, which is categorized as "Excellent" in terms of usability. The system reduced the average letter disposition time from approximately 1–2 days under the manual process to less than 10 minutes. It is concluded that the web-based electronic correspondence system significantly improves the efficiency, accountability, and transparency of administrative correspondence management at BPKAD East Lampung Regency, with future development directions including integration with a digital signature mechanism and a mobile-based notification system.
