Abstract

Pencatatan kehadiran siswa secara manual membutuhkan waktu dan berpotensi menimbulkan kesalahan dalam rekapitulasi data serta praktik titip absen. Penggunaan QR Code statis dapat mempercepat proses absensi, tetapi kode yang sama dapat dibagikan kepada siswa lain sehingga kehadiran aktual siswa sulit dipastikan. Penelitian ini bertujuan memodelkan sistem absensi siswa berbasis QR Code dinamis di SMA Swasta IT Al-Fityah menggunakan Unified Modeling Language (UML). Pengumpulan data dilakukan melalui observasi dan wawancara semi-terstruktur dengan guru atau wali kelas, operator atau petugas piket, serta siswa. Data yang diperoleh digunakan sebagai dasar penyusunan lima diagram UML, yaitu use case diagram, activity diagram, sequence diagram, state machine diagram, dan class diagram. Model sistem mencakup mekanisme pergantian QR Code setiap 20 detik atau setelah dipindai oleh satu siswa. Selain itu, model mempertimbangkan kebijakan penitipan telepon seluler di sekolah dengan menyediakan mekanisme pencatatan kehadiran pada pagi dan sore hari. Pada class diagram, data absensi setiap mata pelajaran dibedakan dari data kehadiran harian, sedangkan hak akses sistem disesuaikan dengan tiga kelompok pengguna yaitu siswa, operator/petugas piket, dan walikelas/guru. Matriks keterlacakan disusun untuk memastikan bahwa setiap kebutuhan fungsional telah terhubung dengan use case, kelas, dan diagram UML yang relevan. Hasil penelitian berupa model UML yang dapat dijadikan acuan dalam pengembangan sistem absensi siswa berbasis QR Code dinamis, khususnya pada jenjang sekolah menengah.

Abstract

Good management in conducting business trips has a positive effect on employees who take business trips and also on the smooth operation of the company. There are so many business travel destinations that are financed directly by the company such as: Business visits, parties, general meetings, educational and training activities as well as socialization. The method used by the author in this study is the Waterfall method which consists of: Requirements, Design, implementation, Verification and Maintenance. The result of this research is to produce an information system for official travel orders that will assist employees in the process of submitting a letter of assignment and the process of calculating official travel costs.

Abstract

Cooperatives as a form of organization that is important in increasing economic growth. Savings and loans cooperatives are one of the alternatives for members to get funds in an effort to improve the standard of living, meet daily needs and develop a business. In addition, savings and loan cooperatives are also one of the options for investing funds (saving). People like to save in savings and loan cooperatives because in addition to the accused, they also get year-end interest or can also get residual business proceeds.  At the Office of Cooperatives and SMEs in Medan Helvetia District, the process of processing savings and loans data is currently still doing manual methods. This kind of data processing can cause insecure data in storage. Therefore, the research will create a data processing system with sufficient computerization. So that the report that will be needed can later be processed appropriately by the Office of Cooperatives and SMEs of Medan Helvetia District. From the problems that have been obtained so that a solution can be obtained from its handling by implementing a web-based savings and loans application, hopefully this application can help the Medan Helvetia District Cooperatives and SMEs Office in handling the problem of processing savings and loan reports so that it does not take time.
