Hi, I'm JK

(Jerald Justin Ko)

Age: 35

Height: 170cm

Languages Spoken: English, smattering of Chinese and Bahasa Melayu
Hosting Style: Flexible

JK is a Full Time Senior Producer Presenter @ Power 98FM

He hosts Power Lunch, 10AM to 2PM weekdays 

An instantly recognizable face on the local events stage and perhaps the loudest voice on air, JK has earned a reputation for being one of the most energetic radio jocks in Singapore Radio since 2010.

Named as one of The Straits Times’ “DJs under 30 to look out for”, he has hosted every time-belt at Power 98FM from the flagship morning show to Evening Drive, Nights, and everything in between.

In his time at the station, JK has spearheaded many campaigns for a variety of clients including Ben & Jerry’s, CLEAR Men, Red Bull, MOTUL, and Nestle. One of his many successful projects includes "Operation Command & Deliver" for SingTel, which won a Singapore Media Award for “Best Use of Radio”.

In addition to his on air duties, JK also hosts #JKAYA, a special interview series available on the Camokakis App, executes client production work, and produces a variety of digital content from long form videos to tiktoks.

He is also the go to man for station events, having organized and led a number of major projects including the annual Power Parties, CARVIVOR, Around the World, LIVE Broadcast Events and more.

The Amazing Race Asia

JK made his debut on television in late 2016 when he was chosen to represent Singapore alongside his co-host Michael Tan for the Amazing Race Asia season 5; making it to eight out of ten episodes, finishing 1st place in 2 consecutive legs.

TARA 5 was a record breaking production, and is the most watched English OP in Asia.

Ah Boys to Men 4

JK's first ever role (albeit tiny) in a Movie Production came in the hugely successful hit production, Ah Boys to Men 4; a film about the misadventures and tribulations of Singaporean men in the reservist phase of their Military National Service.  

Playing the role of a platoon commander who (spoiler alert) falls off a tank in an unfortunate mishap, JK's short but somewhat memorable role (for his friends and family) would forever be a highlight etched in his memory. 

May this be the first of many exciting roles to come.

One of Singapore's most recognized emcees

A familiar face in the events scene; JK's hosting repertoire stretches from intimate to large-scale events, with clients like BMW MINI, ADIDAS, Exxon Mobil, SONY, SENTOSA, American Express, NIKE, Prudential, BEKO, LG Electronics, CPF, MINDEF, UOB, and many more; having flown around the world for events, from Beijing to Kuala Lumpur, Tasmania to Vietnam, hosting shows for a variety of corporate organizations.

He is particularly well known for hosting races, with Asia's leading online running magazine RunSociety calling him "the voice of running events in Singapore". Some of his many events hosted include Nike’s We Run SG, the 2XU Compression Run, The SAFRA Singapore Bay Run, The Hello Kitty Run, SGX Bull Charge, The SWISSOTEL Vertical Marathon, and the Energizer Singapore Night Trail to name a few.

Major Event Highlights include the National Day Parade Celebrations @ Marina Bay Floating Platform, where he took the stage in front of 26,000 screaming Singaporeans for our Nation's Golden Jubilee.




In Demand, Well Traveled, Experienced.

the demand for JK to helm the stage for a variety of clients has seen him travel across the region to host events both immense and intimate. 

To date, JK has hosted for thousands at the heart of the Imperial Ancestral Temple in Beijing, marathons in Kuala Lumpur, as well as various Award Ceremonies, Launches, and Dinner x Dance events in cities like Phuket, Da Nang, Penang, Kuantan, Perth, Shanghai, and Hong Kong.  

Personal Life

JK is an alumnus of the University of Western Australia, and was the face for their UWA Open Day campaign in Singapore. He is currently pursuing his Masters (Media & Communication) at the Wee Kim Wee School of Communication and Information, Nanyang Technological University.

In his free time you can find him messing about in the kitchen in a quest for the perfect sear on a steak (accomplished since November 2017), cycling on night rides with his fellow uncles in tights, swimming at various SAFRA clubs, attempting to play like Scholes on the football pitch, cheering on Manchester United & Daniel Ricciardo, and getting chicken dinners on PUBG mobile.
JK is also an extremely passionate albeit mildly incompetent practitioner of Yoga, and as of 2023 is a father to an impatient 6 year old dinosaur addict and a demanding 3 year old princess.
