For Ruben, this action is not just an ordinary participation, but a historical note in his life journey. He feels proud because the diving certificate he has had for a long time can finally be useful for something noble.
"Yes, this is the first time in my life journey that I can give something to Indonesia, especially on this independence day, and the diving certificate I have is finally useful as well," said Ruben Onsu.
2. Holding a License for Over a Decade
The diving skills of this father of three are indeed impressive, as he has been engaged in this hobby for quite some time. He revealed that he has held the diving license for over a decade.
"Yes, since 2010. This is still one of the things that always accompanies me when I go diving," said Ruben.
3. Unexpected Risks
Even with experience, the underwater world always holds unexpected risks. This famous presenter reminisces about a tense incident he experienced in Labuan Bajo, which he admits was due to his own mistake.
"Once, once. When I was in Labuan Bajo. But that was my own stubbornness. So I was with Luna Maya at that time in Labuan Bajo. At that time, I was about to test a depth of 40 meters in Tulamben, Bali, but I didn't train in Bali, I trained in Labuan Bajo, and then I flew to Bali from Labuan Bajo," he explained.
4. Incident of Nearly Running Out of Oxygen
Ruben further recounts the moment he got separated from his group, including Luna Maya, due to his overenthusiasm. His overconfidence in diving deeper made him unaware that his friends were left behind, until he panicked upon realizing he was alone with dwindling oxygen.
"My oxygen was supposed to last only at a depth of 5 to 7 meters. Because I was going for a depth of 40, Luna was still at 5 meters. 'Ah, this is taking too long', I’ll just dive down alone," he said.
"Eh, I looked around and there was no one. I only realized my oxygen was running out. But that was at that moment. I panicked and got lost, took a long time to surface. Wow, we’re not getting anywhere," he recounted while laughing.
5. Hope for Indonesia
This experience certainly serves as a valuable lesson that makes him much more vigilant and disciplined while diving, including when carrying out the task of raising the flag this time. Closing the discussion, Ruben Onsu expressed his hopes for Indonesia on its 80th anniversary, wishing that all people can feel the true meaning of independence.
"Yes, the hope is that Indonesia is truly independent. Indonesia can really do it, especially all Indonesian people can truly live freely in their own country," he concluded.
