Preservation Principles
Kelajak International Group adheres to the following principles of digital preservation:
Long-Term Accessibility
Digital content is maintained in widely accepted, sustainable formats. Regular reviews are conducted to ensure compatibility with evolving technologies.
Integrity and Authenticity
Digital files are stored securely to prevent unauthorized modification. Checksums and other validation tools are used to verify file integrity.
Redundancy and Backup
Multiple copies of all digital content are maintained in geographically distributed storage locations. Regular backups ensure that data can be restored in the event of system failures or disasters.
Metadata Preservation
Comprehensive metadata is maintained for all digital content to facilitate discovery, retrieval, and understanding. Metadata follows established international standards to ensure interoperability.

Standards Compliance
Kelajak International Group follows internationally recognized preservation frameworks such as:

• OAIS (Open Archival Information System)
• Digital Preservation Coalition (DPC) best practices

Preservation Strategies
File Formats
We prioritize the use of open, non-proprietary, and widely supported formats, such as:

• PDF/A for documents
• TIFF or PNG for images
• CSV/JSON for datasets

For proprietary formats, migration plans are in place to ensure future readability.
Migration and Emulation
Regular format migration is performed to prevent obsolescence.
Emulation approaches may be used when necessary to maintain the functionality of complex digital objects.
Partnerships
Kelajak International Group collaborates with trusted third-party preservation networks and archives to enhance the long-term security of published content.
All papers are archived within reputable digital preservation services (e.g., PKP Preservation Network and similar long-term repositories), ensuring that publications remain secure, stable, and accessible.
Access and Dissemination
Preserved digital content remains accessible through:

• Kelajak International Group journal websites
• Partner preservation platforms

Any access restrictions (e.g., for copyrighted or sensitive materials) are clearly documented and justified.

Monitoring and Review
This Digital Preservation Policy is reviewed annually to ensure its continued relevance and effectiveness. Updates are made as necessary to reflect technological advancements, international standards, and organizational priorities.

Commitment
Kelajak International Group is dedicated to preserving the scholarly record and ensuring that published research remains accessible, authentic, and usable for future generations.
