Triple Helix-Based Applied Research for Strengthening Vocational Students’ Technological Competence: A Coffee Traceability System Case Study
This study demonstrates that a Triple Helix-based applied research model, exemplified by the development of a GPS-based coffee traceability system at Politeknik Negeri Medan, effectively strengthens vocational students' technological competence by integrating authentic project-based learning with real-world industry and community problem-solving.

Imagine a world where schools and the real world of work are like two separate islands. On one island, students learn how to build things in a classroom, using fake materials and made-up problems. On the other island, companies and farmers are struggling with real, messy problems that need real solutions. For a long time, these two islands didn't talk much, leaving students graduating with skills that didn't quite fit the jobs waiting for them. This paper explores a clever bridge called the "Triple Helix." Think of it as a three-legged stool where the legs are the School (the university), the Industry (the businesses), and the Government. When all three sit down together and share a single project, they create a super-powerful learning environment. The paper also uses a recipe called "ADDIE," which stands for Analysis, Design, Development, Implementation, and Evaluation. It's just a fancy way of saying: figure out what's needed, plan it, build it, try it out, and check if it works. The big question here is simple: Can we stop pretending in the classroom and let students solve real problems for real people, so they actually learn how to be experts?
This study dives into a specific adventure in Indonesia where a college team, some coffee farmers, and a couple of coffee companies joined forces to solve a tricky problem. The farmers were having a hard time proving where their coffee came from, which was becoming a huge issue because new international rules (like the ones from the European Union) require every bean to be traceable back to the exact spot it was grown. Without a digital way to track this, the farmers risked losing their best customers.
The researchers, led by a team from Politeknik Negeri Medan, decided to build a "smart" system called Sicafee.id. Instead of just writing a report about how to fix this, they actually built a GPS-based app that lets farmers track their coffee from the farm to the export ship. But the real magic wasn't just the app; it was how they built it. They treated the entire project as a giant, real-life classroom. Eight students worked side-by-side with six lecturers and industry partners, going through every single step of the ADDIE recipe.
The students didn't just guess what the farmers needed; they went into the fields to interview 79 farmers across five different regions. They designed the system using professional tools, coded the app, and then went back to teach the farmers how to use it under the coffee trees. It was a full cycle of real-world engineering.
The results were impressive. When experts checked the system, they gave it a "very good" rating of 88.8%. When the system was tested, every single one of the 20 functional tests passed. Most importantly, when the farmers tried it out, they loved it, giving it an average score of 90.4%. The farmers felt the system was useful, trusted it, and were willing to use it long-term. In fact, the farmers' opinions were so consistent that the researchers noted the farmers' feedback was even more uniform than the experts' technical feedback.
This paper argues that this "Triple Helix" approach is a winning formula. It shows that when students work on a project that actually helps real people, they learn technical skills (like coding and GPS integration) and soft skills (like talking to farmers and solving real problems) all at once. The project didn't just produce a working app; it also created new teaching materials and textbooks that other students can now use. The paper suggests that this model is a powerful way to fix the gap between school and work, proving that the best way to learn is to actually do the work, not just pretend to do it in a lab. The authors are confident that this method works because they measured the results with real data, but they also note that for this to keep working, schools need to keep making sure these projects turn into actual lessons for future students.
