Abstract
Abstract: This study aims to design a web-based employee performance information system at Masa Coffee, Halat Branch, Medan, to replace manual recording of staff attendance and daily task achievement. The system was developed using the Agile Development method in three sprints, each consisting of planning, development, testing, and evaluation. Data were collected through observation, interviews, and document review, and analyzed descriptively together with a requirement analysis. The application was built with Node.js and the Express.js framework and stores its data in a JSON file. Functional testing used Black Box Testing. The result is a system with four modules: user authentication with two access levels, digital attendance, a daily task target form, and a performance recap dashboard for management. All nine test scenarios, covering both valid and invalid inputs, were declared valid. The study concludes that short iterations produced a system that satisfies the functional requirements of a small food and beverage business and is ready for further trial, while its adaptivity to changing requirements and its performance under heavier data loads remain to be tested. Keywords: information system; employee performance; agile development; digital attendance; black box testing. Abstrak: Penelitian ini bertujuan merancang sistem informasi kinerja karyawan berbasis web pada Masa Coffee Cabang Halat, Medan, untuk menggantikan pencatatan manual presensi dan capaian tugas harian staf. Sistem dikembangkan dengan metode Agile Development dalam tiga sprint, dan setiap sprint terdiri atas perencanaan, pengembangan, pengujian, dan evaluasi. Data dikumpulkan melalui observasi, wawancara, dan studi dokumen, kemudian dianalisis secara deskriptif bersama analisis kebutuhan sistem. Aplikasi dibangun menggunakan Node.js dengan framework Express.js dan menyimpan data dalam berkas JSON. Pengujian fungsional memakai Black Box Testing. Hasilnya berupa sistem dengan empat modul, yaitu autentikasi pengguna dua level akses, presensi digital, formulir target penugasan harian, dan dasbor rekapitulasi kinerja untuk manajemen. Seluruh sembilan skenario uji, baik masukan valid maupun tidak valid, dinyatakan valid. Penelitian menyimpulkan bahwa iterasi singkat menghasilkan sistem yang memenuhi kebutuhan fungsional usaha makanan dan minuman skala kecil serta siap diuji lebih lanjut, sedangkan sifat adaptif terhadap perubahan kebutuhan dan kinerja pada beban data yang lebih besar masih perlu diuji. Kata kunci: sistem informasi; kinerja karyawan; agile development; presensi digital; black box testing.
