DESIGN AND DEVELOPMENT OF AN ANDROID- BASED APPLICATION FOR INSPECTING GROUND AND AIR FACILITIES AT BETOAMBARI AIRPORT IN BAUBAU, SOUTHERN SULAWESI

Abstract

Airports play a vital role in the mobility of people and goods, making flight safety highly dependent on the
condition of landside (FSD) and airside (FSU) facilities. Therefore, Betoambari Airport in Baubau requires an integrated
inspection mechanism. This study aims to design and develop an Android application to support the inspection process
using a Research and Development (R&D) approach combined with the 4D model (Define, Design, Develop,
Disseminate). The Define stage involved field observations and interviews to identify user needs. The Design stage
produced a client-server system architecture, a minimalist user interface, and a database schema. In the Develop stage,
a prototype was built using Flutter and Firebase. Testing showed that all functions operated as intended. During the
Disseminate stage, the application was implemented at Betoambari Airport. The application supports daily and monthly
inspections and features damage recording, photo uploads, status updates, and automatic reporting. Data is stored in
JSON format within Firebase and is compatible with Android 10 and above.
