Rice Donation System in Orphanage Based on Internet of Things, Raspberry-Pi, and Blockchain

Abstract

IoT utilization in daily lives is very potential and can be applied in various fields, unfortunately the implementation in the social field still lacking. The large number of orphanages in Indonesia caused information distribution not easily available, however donors find it difficult to get the right information about food reserves, especially rice stock in orphanages. This paper proposes an IoT-based system where rice stocks in orphanages can be detected by Raspberry pi which is connected to sensors, data information from raspberry-pi connected to the network that can be accessed and monitored by mobile applications. This application designed for service providers, donors and rice suppliers. Donors send rice through financial transactions with service providers, and rice suppliers will ship items to the orphanage. Blockchain technology is applied to all parties in order to be transparent and reduce transaction manipulation.
