What is the ruling on one who watched pornography in the daytime during Ramadan, then masturbated?

The one who looked at what is forbidden, practiced masturbation, and broke their fast in Ramadan (definition) has committed a grave sin, because committing a sin in Ramadan is more severe. Therefore, they must repent and make up for the day they broke their fast, and there is no expiation (kaffarah (definition)) required besides that. Abu Hurayrah (may Allah be pleased with him) said: "Whoever breaks a day of fasting in Ramadan without a legitimate excuse or illness, then fasting for a lifetime will not compensate for it, even if he were to fast it." Allah accepts repentance and forgives the sin of whoever repents.
