Design and build a head circumference measurement system for toddlers

Abstract

Growth and development are events that every living thing will experience. These events are two events, namely growth, and development. These two events are related to one another, where growth refers to a change in the shape of the body, or cell size and effect change an organ or limb's function in its operation. Every parent must consider child development because this will significantly determine and influence how the child develops in the future. Measurement of height, weight, or head circumference is carried out at the Posyandu to aim that the development of children under five in an area can be monitored and make it easier to determine policies. The results of this measurement will later be recorded on a card called the "Kartu Menuju Sehat"(KMS). Technological developments bring about considerable changes in the world of health. This paper discusses the design of a head circumference monitoring system. The use of a rotary sensor is an option in designing a head circumference gauge. The measurement results using a rotary sensor show that the measurement accuracy is 100%. Testing the system with a black box shows that 100% of the structure built is acceptable and according to the design scenario.
