The development of technology is increasingly rapid
and growing today, especially in learning media in schools. Along with the
times, training kits are tools needed in learning PJBL (Project Based
Learning), students can learn these tools and try how to use the tools. From
these problems, I made a water level sensor controller and water level.
This research uses research and development (R&D) methods which are
modified into seven stages of research, namely: (1) Analysis of potential and
problems, (2) Data collection, (3) Product design, (4) Product validation, (5)
Usage trials, (6) product revisions, (7) Product trials, (8) Design revisions,
(9) Product revisions and (10) mass products. The research used class XI
Industrial Electronics Engineering. The validation research instrument uses the
assessment of 4 Validators according to their respective field experts.
Based on the results of the study, it can be
concluded that the water level sensor water control system can work well as
expected, namely at the controller level and the water level in the water
reservoir automatically. The results of the statistical data from the one
simple T-test show that the calculated t value is 9,362, the df (degree of
freedom) value is 20. The sig (2-talled) value or
2-talled value or test value two-sided is 0.011 and from the data and results
of the binomial test.
