About Technical & Sustainability Digest

Where automation meets sustainability, and field notes become shared knowledge.

Technical & Sustainability Digest is an independent publication founded in July 2025 by Ketut Kumajaya. It shares technical insights, sustainability perspectives, and field‑based documentation drawn from real industrial experience.

The author works professionally in the industrial gas and process automation sector, where real‑world challenges often inspire the topics discussed here. However, this site is an independent work — not affiliated with or endorsed by any company or organization. All opinions and analyses are entirely personal and shared for educational and documentation purposes.

A mirror site, Automation Blog, hosts an identical copy of all articles. It safeguards the archive against infrastructure risks and ensures long‑term availability through GitHub Pages.

All content is openly published and accessible to everyone — no paywalls. No subscriptions. No algorithms deciding what you should read. The goal is simple: to share knowledge, preserve learning, and keep curiosity alive.

Powered by Open‑Source

Access and Updates

Transparent, versioned, and open for learning.

The full archive of posts is freely available on this site. You can follow updates through the RSS feed or by visiting the connected GitHub repository. The repository itself is part of this philosophy — transparent, versioned, and open for exploration.

A Space for Practitioners and Thinkers

Not a corporate channel — a workshop of ideas.

This blog welcomes readers who share interests in industrial automation, system design, and sustainability. For engineers who see beyond schematics, and for thinkers who value the lessons hidden in field notes.

Every reflection, comment, and discussion is valued — because knowledge grows stronger when it flows, not when it’s locked away.
