There are two basic ways of making a Half Hitch. It can be tied off with a running end, or it can be tied off with a bight, which makes it a Slipped Half Hitch.

1 Bring the running end around the ring and then around its standing part. Then, tuck the end inside the crossing turn, next to the ring.

2 Another option is to make a last tuck with a bight, making it a Slipped Half Hitch.

The Half Hitch makes a very quick and temporary tie off. It is also tied as the first step of other more secure hitches. The slipped version unties completely with just one pull.
