Abstract

Biji kopi yang diolah oleh home industri masih banyak yang belum memiliki mesin pengayak biji kopi, dan produk yang dihasilkan masih banyak ukuran yang belum memenuhi standar, sehingga daya jual biji kopi murah.Untuk mengatasi masalah tersebut akan dirancang mesin pengayak biji kopi dengan skala home industri 300 kg / jam. Penelitian ini bertujuan mendesain dan mensimulasikan mesin sortir biji kopi agar dapat memisahkan ukuran biji kopi yang memenuhi standar, sehingga dapat menghasilkan biji kopi konsumsi dengan ukuran yang memenuhi SNI biji kopi konsumsi, mesin sortir ini khusus digunakan untuk biji kopi jenis robusta. Desain alat menggunakan 3 buah wadah alumunium yang disusun secara bertingkat. Setiap wadah memiliki lubang-lubang dengan diameter yang berbeda yaitu 7 mm, 5 mm, dan 3 mm. dan di harapkan mesin ini mampu mensortir 300kg/jam. Kata kunci: Desain mesin sortir, biji kopi kering, kopi robusta

Abstract

Student attendance is a crucial component of school administration, directly linked to discipline and attendance evaluation. At MA Nurul Falah, attendance recording is still conducted manually, which takes approximately ±10 minutes per class. This method is not only time-consuming but also prone to recording errors, negligence, and data loss. These issues can affect the accuracy of attendance data, which in turn impacts academic assessment and student discipline evaluation. This study aims to design and develop an Android-based student attendance information system that enhances the efficiency and accuracy of attendance recording. The research employs a Research and Development (R&D) approach using the Waterfall development model, which is suitable for building systems in a structured and systematic manner. The application is developed using Java and PHP programming languages, with MySQL as the database and Android Studio as the development environment. System testing is carried out using the BlackBox method to ensure all functionalities work as expected, along with a usability evaluation using the System Usability Scale (SUS) to measure user satisfaction and ease of use. The testing results show that the application reduces attendance recording time to approximately ±2 minutes per class (an efficiency improvement of around 80%), with a 100% success rate in functionality across various Android devices. This system offers a digital solution that is effective, efficient, and modern for managing student attendance. It is expected that the system can be further adopted and expanded by other educational institutions as a reference in implementing digital-based administrative processes in schools.
