PARI (PApaya Ripeness Identification)

PARI is a system designed to classify the ripeness of papaya (Carica papaya) using ultra-high frequency electromagnetic waves. The system employs Radio Signal Strength Indicator (RSSI) technology to measure the interaction of electromagnetic waves with the fruit. By analyzing the RSSI values, PARI accurately determines the ripeness stage of the papaya in a non-invasive manner.

PARI is actively being developed as a Minimum Viable Product (MVP) for the "Gemastik 2024 XVII Smart Device, Embedded System & IoT" competition by Balai Pengembangan Talenta Indonesia (BPTI), Pusat Prestasi Nasional (Puspresnas) & Kementerian Pendidikan, Kebudayaan, Riset, dan Teknologi (Kemendikbudristek) and is not an application for production purposes.
