Ignatius Rosoinaya Penyami, better known as Igor and professionally as Saykoji, is an Indonesian rapper born on June 8, 1983, in Balikpapan, East Kalimantan, and is currently 35 years old.
Saykoji gained public recognition with his debut single "So What Gitu Loh" in his first album, released in 2006, which marked a successful comeback after the era of Iwa K dims. The album also featured successful singles "Jomblo" and "Deep Debut" that resonated with the younger generation.
Following the success of his first album, Saykoji released a second album, which included singles "Cockroach Ngesot" and "Jomblo", and also participated in a compilation album released by EMI.
Saykoji, initially consisting of only Igor, was previously not a fan of rap music, considering it unclear in chanting poetry. However, after listening to Indonesian rap musicians Black Skin, Iwa K, and Neo, he developed a liking for the genre and further studied it. He chose the name Saykoji, derived from his nickname as a loner student, which was once called "psycho" by his peers.
In his stage formation, Saykoji often collaborates with Guntur Simbolon and Della MC from Batik Tribe. Igor also has a spiritual group called Disciples, consisting of three friends: JFlow, Guntur Simbolon, and Rendy Rainhard.
In mid-2009, Saykoji released a new single titled "Online", which quickly gained popularity and was even used as a theme song for a cell phone product. He also released a controversial single titled "Copy My Style", which addresses the issue of copyright infringement.
In 2010, Saykoji released an album titled "Narcissistic".
