Incremental rotary encoder is a sensor that can be used to measure the degree of rotation in ship steering simulations. To create a ship steering simulation, Visual Basic software was used to simulate the movement of the rudder and ship. Meanwhile, to obtain incremental rotary encoder reading data, serial communication is used via Universal Serial Bus (USB) media bridged by Arduino which is programmed to convert incremental sensor signals into ASCII signals with a bolt rate of 9600 bps. The aim of this research is to test the accuracy level of the incremental rotary encoder sensor in ship steering simulations using Visual Basic software on commercial ships by using the Solas rule that a ship's rudder must comply when rotated from the midship position to the 35 degree port side position followed by the 35 degree position. starboard side and returning to midship, the rudder movement time was less than 28 seconds. Test results in terms of response speed of the incremental rotary encoder sensor are very good, while in terms of accuracy level for one degree of steering rotation, the result is 4.571 on the Arduino IDE serial monitor reading..

Creativity if poorly developed from an early age can adversely affect future life. A child who cannot develop his creativity will lose confidence in him in the future because he feels in him there is nothing to be encouraged about. Promoting a child's creativity requires stimulus using a teaching strategy or method. The need for creativity to be developed at an early age is because at this age the child-children have the ability to respond to everything from the outside quickly. In addition to clean and healthy living behaviors (PHBS) in the school ward are conscious efforts of students and teachers to prevent disease, freeing a healthy environment from illness. The stages of brain development in preteens occupy the fastest possible position of up to 80% of brain development. The goal of devotion is to foster creativity and deliver health education in children of an early age.
