Wiyono (often credited by his full name, Ari Wiyono or Sugeng Wiyono) is the highly versatile actor who plays Pak No Galino and Sentun in the viral Javanese YouTube comedy series Woko Channel. He is widely recognized as one of the channel's most talented character actors. His most prominent roles include Pak No Galino (a flirtatious, short-tempered older man with a long black mustache who hilariously tries to chase younger women), Sentun (a comedic character known for his signature catchphrase "Glogok njaran...") and Mbah Karso (an eccentric, long-bearded spiritual healer or shaman character). Like his co-stars, before transitioning to full-time YouTube creation, he was a professional dangdut orkes guitarist performing at neighborhood wedding celebrations (hajatan) around Kediri, East Java. Beyond acting, he works closely behind the scenes alongside director Pak Woko, often helping to flesh out script dialogues and inject the distinct, rapid-fire Javanese humor that the channel is known for.
