Abstract

This research focuses on the development of a coffee fruit sorting system, which is a part of an embedded automation system for coffee processing and storage. The implementation of this system aims to improve and maintain the quality of coffee throughout the production and storage processes. The embedded automation system for coffee processing begins with the coffee fruit sorting system, which is responsible for selecting perfectly ripe and high-quality coffee fruits. Subsequently, the system proceeds with coffee bean production and storage processes. The developed system comprises small-scale subsystems capable of performing various coffee processing tasks. These subsystems can be integrated to form a larger system capable of handling coffee production and storage processes. The research utilizes software technology embedded in the hardware system. The employed software technology is a component of an intelligent control system, which utilizes artificial intelligence as its underlying control mechanism. The maturity classification of coffee fruits is divided into three classes: KM (immature), MM (mature), and MS (fully mature). This classification scheme simplifies the understanding of the sorting process.

Abstract

Absensi secara online adalah salah satu bentuk pemanfaatan dari kemajuan teknologi informasi yang kini telah banyak diaplikasikan di berbagai instansi, khususnya di bidang pendidikan. Meskipun demikian, sistem absensi mahasiswa Program Studi Teknik Informatika di Universitas Papua masih menggunakan metode manual yang rentan terhadap potensi kecurangan seperti titip absen atau manipulasi data kehadiran. Oleh karena itu, penelitian ini bertujuan untuk membangun dan merancang sebuah aplikasi absensi mahasiswa berbasis Android dengan memanfaatkan teknologi QR Code dan geolocation sebagai metode verifikasi kehadiran mahasiswa. Aplikasi ini mengimplementasikan fitur geolocation yang bergantung pada GPS, sehingga absensi hanya dapat dilakukan di lokasi Fakultas Teknik yang telah ditentukan. Selain itu, teknologi QR Code memungkinkan proses identifikasi dilakukan secara cepat dan akurat melalui pemindaian. Penelitian ini menggunakan metode Rapid Application Development (RAD) yang mendukung proses pengembangan perangkat lunak secara iteratif dan cepat. Prototipe aplikasi dirancang menggunakan Figma, kemudian dikembangkan menggunakan Android Studio sebagai Integrated Development Environment (IDE). Aplikasi yang dihasilkan diharapkan dapat meningkatkan efisiensi, akurasi, dan keamanan dalam proses pencatatan kehadiran mahasiswa serta mempermudah dosen dalam melakukan rekapitulasi data kehadiran secara digital.
