Project Overview

This project aimed to create a streamlined online registration platform for the UTBK-SNBT exam, simplifying the application process for aspiring university students. Our project focuses on creating an efficient and user-friendly online registration platform for the UTBK-SNBT exam, addressing various complex requirements to accommodate a large number of applicants.

Problem Statement

The challenges encompass multiple aspects of the registration process:

  1. Comprehensive Application: Designing a user-friendly form for applicants to provide personal information, family details, and disabilities (tuna netra and tuna daksa), ensuring inclusivity.
  2. University Selection Constraints: Implementing logic that restricts KIP-K recipients from applying to PTKIN/UIN institutions due to specific regulations.
  3. Subject Portfolio: Developing a feature for applicants to submit subject portfolios where required.
  4. Pusat UTBK Seat Booking: Ensuring a queue-based seat booking mechanism for Pusat UTBK to prevent concurrency issues and ensure unique seat assignments and payment codes.
  5. Secure Cards and Certificates: Designing secure Kartu Pembayaran, Kartu Peserta, and Sertifikat UTBK with encrypted QR codes to prevent tampering.
  6. Handling High Traffic: Strategizing for optimal performance and minimal downtime while accommodating a significant volume of 800,000 applicants.
  7. Payment Expiry Management: Releasing exam seats within a specified time frame if payment is not made, allowing other applicants to utilize those seats.

Solution and Features

To address these challenges, our UTBK-SNBT registration platform provides:

  • Intuitive Form: A streamlined application form with sections for personal details, disabilities, and family information.
  • Dynamic University Selection: Logic to enforce university selection constraints based on KIP-K status.
  • Subject Portfolio Upload: A user-friendly interface for uploading subject portfolios where applicable.
  • Pusat UTBK Queue: A queue-based seat booking system at Pusat UTBK to ensure seat allocation integrity.
  • Secure Certificates: Sertifikat UTBK with encrypted QR codes to securely display exam scores.
  • Scalable Infrastructure: Employing robust architecture to handle high traffic and ensure performance.
  • Payment Expiry Handling: Automated release of unpaid seats to optimize seat utilization.

Technologies Used

The project was meticulously crafted using a comprehensive tech stack, including:

  • Frontend: Next.js, a powerful React framework, was chosen for its server-rendering capabilities, coupled with Chakra UI for a modern and consistent design language, resulting in a seamless and visually appealing user experience.
  • Backend: Laravel, a robust PHP framework, was employed to build the backend infrastructure, with OpenID Connect used for secure and seamless authentication, ensuring user privacy and data protection.
  • Database: Firestore, a scalable and real-time cloud database by Google Cloud Platform (GCP), was utilized to efficiently manage and store data, offering a reliable foundation for the application.
  • Infrastructure: Google Cloud Platform (GCP) served as the backbone for the project's infrastructure, providing a scalable and secure environment to host and manage the application.
  • Security: The implementation of encrypted QR codes added an extra layer of security, ensuring the integrity of critical data throughout the application.

Design and User Experience

The platform's design prioritizes simplicity and clarity, ensuring an effortless application process for all users. The user interface was optimized for both desktop and mobile devices.

Development Process

The project followed agile methodologies with continuous iterations and close collaboration between frontend and backend teams.

Results and Impact

Since its launch, the UTBK-SNBT registration platform has exhibited remarkable results and positive impact:

  • Enhanced User Experience: The integration of Next.js and Chakra UI contributed to a smooth and intuitive user interface, resulting in increased user satisfaction.
  • Streamlined Registration: The utilization of Laravel and Firestore allowed for efficient data management, leading to a seamless and error-free registration process for applicants.
