VOLLEYBALL REFEREEING SCORE SHEET LEARNING DEVICE APPLICATION-BASED

The purpose of this research is to produce a new product in the form of the use of score sheet application devices in the learning of volleyball refereeing courses. In volleyball matches, there is a match organizer that records the flow of the line-up, the executor of the service, rotation of players, game points, substitutions, final set, a captain in the team, libero players, and the results of the overall match which at the end of the match will be recorded in the form of print outs.

According to Sugiyono (2017: 407), who uses 10 steps, namely: (1) identification of potentials and problems, (2) collection of information data, (3) designing, (4) design validation, (5) design improvements as validation results, (6) product trials in the form of prototype, (7) product revisions, (8) usage trials, (9) product revisions, (10) product mass production. The approach used in this research is a qualitative approach and quantitative approach.
