The German tactician, who only spent 81 days in charge of Yanga, was on the touchline for Saturday's Super Clash.
Alger raced into a two-goal lead in the first half through goals from Sofiane Bayazid and Ayoub Abdelloui.
Ramovic's side hit back in the 72nd minute after Aymen Mahious converted a penalty, before the same player sent the game to penalties after scoring the equaliser in the 88th minute.
South African striker Khanyisa Mayo managed to score his penalty in the shoot-out, while Naoufel Khacef and Mahious saw their spot-kicks saved as Alger triumph 4-3.
Ramovic will now turn his attention to the Ligue 1 campaign, where Belouizdad currently sit two points behind Alger in second spot.
