During this time the mother in pumping breast milk using manual Breastpump, where the manual Breast Pump does not adjust to pressure or time. This study aims to design an “Portable Breast Pump Elektrik dilengkapi Pengatur Tekanan dan Pengatur Volume ASI” in order to facilitate nurses, midwives and mothers in pumping breast milk. Making modules using the photodiode sensor as a volume detection sensor.In the results of testing this module, obtained an average value of pressure at low 55.14 mmHg, medium 98.7 mmHg and hight 130.42 mmHg n each interval. this causes pressure selection to be adjusted to the user's needs
