Abstract

Measurement of the outcomes becomes a vital part in OBE system to ensure the attainment of each outcome. In Indonesia, OBE was adopted in 2015 for higher education level. However, the changes were not accompanied with clear method to measure the outcomes, which became the urgency of this research. In this study, a preliminary method to measure student learning outcomes (SLO) and course learning outcomes (CLO) was presented. The measurement of SLO and CLO attainment was started by SLO mapping to courses, which usually had been done at curriculum design. Based on the mapping, formulation of CLO with a set of direct assessment was planned at the start of each course. After the teaching learning activities, a series of calculation was designed to obtain the attainment of SLO and CLO for each student, course, and whole study program. In the same time the final mark for GPA calculation of each student could also be obtained. The designed method could play an essential part in teaching-learning quality assurance and curriculum continuous improvement, which is aligned with both international and national accreditation criteria and standards. Furthermore, this study could provide insight for other study program in SLO and CLO attainment measurement.

Abstract

This research presents a secure digital-signature framework for document authentication using QR Codes, combining three modern cryptographic primitives: RSA 2048-bit for digital signing, SHA-256 for document-integrity verification, and password-based AES encryption to protect the signer’s private key. The system addresses a recurring limitation in previous QR-Code-based signature schemes—the absence of secure private-key storage—by deriving AES keys from user passwords and salts, ensuring that RSA private keys are never stored in plaintext. A web-based implementation was developed to support user registration, signature generation, and document verification, requiring only a PDF file and the associated password from users. Functional testing demonstrates that the system accurately authenticates signer identities, detects any modification to document content, identifies incorrect document numbers, and rejects invalid or non-signature QR Codes. These results confirm that the combination of RSA 2048, SHA-256 hashing, and password-derived AES encryption effectively ensures confidentiality of private keys while preserving document integrity and authenticity. The approach also prevents common forgery scenarios, including document substitution, unauthorized content changes, and QR Code misuse.
