Cadet Worksheet (CW) Design to understand how to determine the area of the water plane (WP) and tons per centimeter of immersion (TPC) using the Simpson 1/3 formula

The aim of this research is to determine the quality of the Cadet Worksheet (LKT) design and to find out how the LKT design is suitable for use to understand how to determine the area of the Water Plane (WP) and Tons per Centimeter Immersion (TPC) using the Simpson 1/3 formula. This research is a qualitative research type of intrinsic case study. Researchers develop the LKT design, then determine the quality of the LKT design based on the validator's opinion. The quality of the LKT design is in the very suitable category with a KyDr gain of 92%. In addition, an LKT design that is suitable for use to understand how to determine the area of the water plane (WP) and tons per centimeter of immersion (TPC) using the Simpson 1/3 formula must contain a course identity that contains learning objectives, an introduction, namely contextual problem orientation, activities that aims to understand prerequisite material, concept discovery activities, activities to apply concepts, practice questions to deepen concepts.
