Swinged the baby is one way movement for all bodies and must be done smoothly because if not would generate situation of so-called with term ´ shaken baby syndrome´ which because of way candle or sway the too hard or too boisterous at baby. Sway the baby too boisterous will make the baby head terguncang forwards and rear. In this time there are some the baby cradle types for example; baby cradle with long string. To sway the baby with this type of have to be started with boisterous oscillation so that oscillation take place the llama, this matter rentan the happening of guncangan [at] brain and generate damage of brain. Oscillation with short string. Cradle this type of have to be swayed continuously so that the mother or nursemaid have to fixed reside in the place and cannot do the other work. Pursuant to the mentioned is innovate the healthy cradle for baby and can sway by self with speed and deviation remain to without needed to sway by using pendulum oscillation principle at with title Inovasi Ayunan Bayi Sistem Otomatis Dengan Prinsip Jam Bandul. Pursuant to designing to wake up the baby oscillation with pendulum system and result analyse and evaluate from the appliance test-drive inferential that is 1.Prinsip applicable pendulum [hour/clock] to make the oscillation can sway by self. 2.Energi to do the the oscillation is got from potential energy from pemberat which altered become energi oscillation motion through mechanism anchor and gear be like pendulum. Oscillation with this pendulum system still has weakness and need some completions to be able to work better.
