The Pacific Plate
Mauna Loa is not located on a plate boundary. Mauna Loa is caused by a stationary hot spot in the Earth's mantle.
Mauna Loa is on the Pacific Plate. It is not near any other plates.
What type of magma is produced in mauna loa?
If we consult a map showing tectonic plates, we can see that Mauna Loa is on the Pacific plate. The general rule is that volcanic activity usually appears along plate boundaries, but Mauna Loa and the Hawaiian Islands sit on what is called a hot spot in approximately the middle of Pacific plate.
The tectonic plate that Mauna Loa sits on is moving northwestward over a hot spot in the Earth's mantle, creating a chain of volcanic islands in the Hawaiian archipelago. As the plate moves, new lava erupts on Mauna Loa, adding to its size and height. The volcano periodically erupts, releasing pressure from the magma chamber beneath it.
It's on a hot spot, not a plate boundary.

Mauna Loa is on a hotspot known as the Hawaiian hotspot. This hotspot is responsible for the formation of the Hawaiian Islands, including Mauna Loa, due to the movement of the Pacific tectonic plate over a stationary mantle plume.
