Melt the butter in a saucepan over medium-high heat. Stir in onion, and cook until tender. Mix in rice, and season with cumin, garlic powder, onion powder, pepper, cayenne pepper, and salt. Cook and stir until rice is golden brown. Pour in orange juice and broth, and bring to a boil. Reduce heat to low, cover and simmer 20 minutes.
Remove cooked rice from heat, and gently mix in cilantro to serve.
