Tumbler Tuku is currently a hot topic among Indonesian netizens, with Andanu Prasetyo being at the center of it all. The disappearance of Anita Dewi’s Tumbler Tuku on a train caused quite a stir and led to a peaceful mediation between Anita and PT KAI officer, Argi. Established in 2015 by Andanu Prasetyo, Toko Kopi Tuku is now a successful coffee brand with over 72 stores across Indonesia. In fact, even Jokowi visited the Toko Kopi Tuku in Cipete, South Jakarta on July 2, 2017. The Tumbler Tuku incident involving Anita Dewi on the train has sparked a wave of discussions on social media lately. It all started with Anita reporting the disappearance of her Tumbler Tuku while traveling on a train. The incident went viral, causing repercussions for a PT Kereta Api Indonesia (Persero) officer named Argi. Argi, who works as a passenger service at Rangkasbitung Station in Banten, faced consequences due to the Tumbler Tuku incident. Rumors of Argi’s dismissal circulated, but PT KAI later denied the claims. Meanwhile, Anita Dewi faced criticism for making a fuss over the lost Tumbler Tuku. Some netizens blamed her for the incident. However, after a mediation on Friday, November 28, 2025, things were resolved amicably between Anita Dewi and Argi. Moving on from the previous news, who is the person behind Tumbler Tuku? Andanu Prasetyo’s Role. According to a report by Tribunnews.com, Tumbler Tuku’s success is closely linked to the presence of Toko Kopi Tuku, managed by PT Makna Angan Karya Andanu (MAKA).
