Thanks for the alert, Christine. I know nothing about grass, so I would definitely have overlooked this post.
The plant is a type of Chamaedorea Palm. It looks to be in a good location for light and appropriately potted.
The brown leaf tipping does not appear to be extensive and is within the realm of normal tipping which can occur in less than ideal light or less than perfect watering. It is not a humidity issue.
Trim off the brown tips so you don't have to continue looking at them. You may be letting the soil get a bit too dry between waterings. But don't make any major changes in your watering. Afterall, it looks great after a year so you are only slightly less than perfect!
If you ever see new fronds coming in discolored, that is a good indication of the soil staying too wet.
