Cookies are a type of biscuit made from soft dough, high in fat content, relatively crispy when broken, and have a dense cross-sectional texture. The significantly increasing data on wheat flour consumption indicates a very high level of dependence on wheat flour. This is due to the high number of processed food products using wheat flour, necessitating the utilization of flour from local raw materials to explore local potential, one of which is by partially replacing wheat flour with purple swe...

Misconceptions still often occur when learning physics, especially in conducting research that is not consistently detailed in identifying an observation. In parabolic motion material, it is known that 45° is a special angle that produces the farthest distance. The misconception that 45° is the angle that produces the farthest distance has become a reference in learning in various educational institutions to date. The aim of this research is to identify and prove that the 45° angle is not an ele...
