Introduction

The new student admission process (PPDB) is a critical gateway for any educational institution. However, SMKS Jakarta 1 Pondok Kopi faced a significant 35.4% decline in applicants between 2021 and 2024, caused by an inefficient and fragmented admission system.

The core problems include:

• Outdated information platforms — prospective students struggled to access accurate enrollment information.
• Complex multi-platform registration flow — applicants had to move between platforms, increasing the risk of input errors.
• Error-prone manual payment verification — payment records were matched one by one by hand.
• Insecure online exam system — vulnerable to cheating and unreliable.

Research Objectives

This research aims to develop an integrated web-based student admission (PPDB) information system that combines every stage into one complete flow:

1. Registration — enrollment of prospective students in a single unified platform.
2. Digital payments — payment gateway integration so payment verification is automatic and accurate.
3. Online exam with anti-cheating features — a secure and supervised selection process.
4. Centralized announcements — results are published through one official channel.

Methodology

The system was developed using the Waterfall model, applied in five stages:

1. Requirements analysis — collecting the school's admission workflow and pain points.
2. Design — modeling the integrated system and its database.
3. Implementation — building the web-based system, including the payment gateway and online exam modules.
4. Testing — verifying each feature against expected behavior.
5. Maintenance — supporting deployment and future refinements.

Evaluation was carried out in two stages:

Stage	Method	Result
Functional Testing	Black Box Testing	All functionality worked as expected
User Acceptance	User Acceptance Testing (UAT)	Average score of 4.48/5.00 from prospective students and 4.50 from the committee

The UAT results produced a final interpretation of "Very Good", showing that the system was very well received by both user groups.

Practical Implications

Implementing this system delivered significant improvements in:

• Administrative efficiency — registration, payment, and announcement processes no longer take a long time.
• Data accuracy — automated payment verification reduces human error.
• Modernized school services — an image of the school as a technology-adaptive institution.

Research Contribution

This research contributes by providing and validating an effective integrated PPDB system model, proving it as a comprehensive solution for vocational education institutions — not only for SMKs, but adaptable by other educational levels.

Conclusion

The integrated PPDB system with payment gateway and anti-cheating online exam proved effective in solving the previously fragmented enrollment problem. With a "Very Good" acceptance level, this model becomes a reference implementation for educational institutions that want to modernize their academic administrative services.
