Narrative:
Approach called to ask if small aircraft X had changed to my frequency advising that he had come over on his own and did not have small transport Y (who I was talking to) in sight. During that conversation with approach, small aircraft X called in. I answered with instructions to turn right 10 degrees and called traffic. The pilot did not respond. I then called traffic to small transport Y followed by instructions to small aircraft X to turn right 15 degrees, again no response. I then issued a traffic alert to small transport Y who stated he had small aircraft X in sight. I continued to call small aircraft X. He acknowledged a turn but turned left instead of right as instructed. Small transport Y was cleared to land. Small aircraft X to follow traffic. In my opinion he followed too close and I instructed small aircraft X to make a right 360 degree turn. After 3 calls he then executed a left 360 degree turn but it did provide adequate spacing to the runway.

Title: TRAFFIC CONFLICT OCCURRED BETWEEN AN SMA AND SMT WHEN THE SMA DID NOT FOLLOW DIRECTIONS.
Narrative: APCH CALLED TO ASK IF SMA X HAD CHANGED TO MY FREQ ADVISING THAT HE HAD COME OVER ON HIS OWN AND DID NOT HAVE SMT Y (WHO I WAS TALKING TO) IN SIGHT. DURING THAT CONVERSATION WITH APCH, SMA X CALLED IN. I ANSWERED WITH INSTRUCTIONS TO TURN R 10 DEGS AND CALLED TFC. THE PLT DID NOT RESPOND. I THEN CALLED TFC TO SMT Y FOLLOWED BY INSTRUCTIONS TO SMA X TO TURN R 15 DEGS, AGAIN NO RESPONSE. I THEN ISSUED A TFC ALERT TO SMT Y WHO STATED HE HAD SMA X IN SIGHT. I CONTINUED TO CALL SMA X. HE ACKNOWLEDGED A TURN BUT TURNED L INSTEAD OF R AS INSTRUCTED. SMT Y WAS CLRED TO LAND. SMA X TO FOLLOW TFC. IN MY OPINION HE FOLLOWED TOO CLOSE AND I INSTRUCTED SMA X TO MAKE A R 360 DEG TURN. AFTER 3 CALLS HE THEN EXECUTED A L 360 DEG TURN BUT IT DID PROVIDE ADEQUATE SPACING TO THE RWY.
