PERANCANGAN COOLER BAG ASI (AIR SUSU IBU) OTOMATIS MENGGUNAKAN THERMOELECTRIC BERBASIS ARDUINO

Breast milk (breast milk) is an important staple food for babies because it contains nutritional value, besides that breast milk can also maintain the baby's immunity and prevent babies from getting sick. The WHO itself also recommends that exclusive breastfeeding should be given to babies for the first 6 months. The importance of breastfeeding for babies has also received an appeal from the government, especially for working mothers, the obstacles experienced by working mothers are related to storing breast milk, because it is necessary to know that the shelf life of breast milk is short and the room temperature factor. Therefore, the author came up with an idea to design a smart device in the form of an Arduino Uno-based automatic cooler bag that is easy to carry anywhere. It also aims to make it easier for working mothers to store breast milk and provide exclusive breastfeeding to babies. This cooler bag is made using the Peltier module TEC-1706 series which uses a battery voltage of 12 Vdc 6 Ampere and this tool is also equipped with an expiration indicator using the RTC DS3231 module as a time clock system and a buzzer as a sound indicator, so that breast milk is kept safe before being given to baby.
