The availability of electricity is very important to meet people's basic needs. Including island communities and remote areas. In September 2020, the South Sulawesi government stated that electricity was one of the triggers for investors to be interested in investing. Tanakeke Island is an agrotourism island area that does not yet have electricity supply but is rich in marine biota, especially turtles. Turtles are one of the marine biota that are conserved and cultivated to ensure their survival. Hatching turtle eggs is not easy, considering that there are criteria that must be met in determining the quality of temperature and humidity of hatching turtle eggs. The ideal temperature for hatching turtle eggs is around 24°C to 32°C with humidity around 68%RH. This research aims to design and manufacture a Mini Gasebo Smart System using photovoltaic as alternative electrical energy in island areas. This system is integrated with a turtle egg hatching system which is controlled using a microcontroller connected to the internet and uses Firebase as a database and Android platform to display the controlled variables. This mini gassebo system for hatching turtle eggs can become an agrotourism system for Tanakeke Island for turtle conservation. The turtle hatching room is designed to be a unique transparent table that allows you to see the condition of the turtle eggs. The system can control ideal air temperature and humidity via an Android application in real time and displays a history of previously measured temperatures. [ABSTRACT FROM AUTHOR]

Infusion is a health device which, under certain conditions, is used to replace lost fluids and balance the body's electrolytes. The current situation is that almost every inpatient in polyclinics, health centers and hospitals use Intravenous fluids. The use of conventional infusion sets is actually not that problematic, patients can be controlled and monitored periodically for a short time by nurses. However, this often causes problems due to several factors such as a lack of human resources in hospitals, negligence by nurses, and even the actions of the patients themselves. From this problem, a system was created to detect the minimum limit for infusion fluids using a WEMOS microcontroller. The system created is capable of measuring the capacitance value of infusion fluids using a Non-Contact Liquid Sensor and is connected to an Android application based on a microcontroller and cloud storage. The system will provide notification to the nurse station in the form of information about the room where the infusion must be replaced immediately. The system also provides notifications in the form of sound and vibration so that the patient's guardian can immediately know the condition of the IV fluid that must be replaced immediately.
