Janji Jangan Ngebul

A public campaign asking truck makers to stop the smoke and keep their promises: brand, message testing, collateral, and the website.

The ask

Purpose Indonesia wanted a public campaign that puts the pressure where it belongs: on the manufacturers who could bring affordable electric trucks to Indonesia and have not. It had to reach working-class commuters and worried mothers in relatable, witty Indonesian — no lecture, no NGO beige. The name was already set: Janji Jangan Ngebul, a promise not to ngebul.

What we did

  • Message testing — three audiences, five messages, carousel creative for Instagram, Facebook, Threads, and LinkedIn, so the campaign launched on lines that had been tried rather than guessed.
  • Logo and brand book — a tilted, street-pop logo family in twilight purple, tree green, and electric yellow, with the wit of Pantura truck-tailgate poetry and none of the pastiche.
  • Mascots and collateral — Rosie and the drivers; stickers (Ngeeeng tanpa ngebul, Gas sampai nol, Kutunggu truk listrikmu), e-money cards, caps, sunglasses, scarves.
  • Booth — a 3 × 2 metre stand for the soft launch at INZS 2026.
  • Website — janganngebul.com, a custom WordPress theme we built and host: the case, a library of the facts, and a “do something” page with newsletter sign-up and sharing.

What happened

Brief in late June; soft launch at INZS on 1 August 2026; full site and brand book delivered by mid-August. The campaign is live and young. We will add numbers here when there are numbers worth adding.
