The best presentations you will ever give are the ones where you genuinely love the topic and you're telling an entertaining story about the material. If it's at all possible, do the presentation on something you enjoy, or the parts of a topic that you enjoy. And dont be afraid to strip your presentation down. Go slow, tell one story with a narrative arc, otherwise you lose people.
Worst case, do your damndest to trick yourself into thinking you love the topic. I've had to do this a couple times for subjects I found absolutely boring, and had people comment afterward that I really seemed like I loved the material.
