Abstract
PT Wijaya Karya Beton Tbk merupakan sebuah anak perusahaan dari PT Wijaya Karya (Persero) Tbk yang bergerak di bidang industri beton pracetak. PT Wijaya Karya Beton Tbk melaksanakan kegiatan audit internal untuk mengevaluasi kinerja perusahaan. Kegiatan audit internal pada PT Wijaya Karya Beton Tbk masih dilaksanakan secara konvensional sehingga menyebabkan permasalahan seperti paper waste, waktu yang kurang efisien dalam menyelesaikan suatu proses, dan keterlambatan pengiriman laporan hasil audit maupun RTP. Dari masalah yang ada, maka penelitian ini dilakukan dengan tujuan untuk melakukan analisis dan perancangan sistem informasi yang dapat mempermudah pelaksanaan audit internal. Metode yang digunakan pada penelitian yaitu model Waterfall. Pada tahap analisis kebutuhan dilakukan diskusi, wawancara, dan studi dokumentasi dengan Biro Quality, Safety, Health, Environment & Sistem Manajemen (QSHE & SM) untuk menggali kebutuhan, lalu pada tahap perancangan sistem dilakukan perancangan berdasarkan hasil analisis kebutuhan dengan pendekatan berorientasi objek. Setelah analisis dan perancangan selesai, maka dilakukan evaluasi terhadap hasil analisis dan perancangan tersebut. Dalam penelitian ini, dihasilkan pemodelan proses bisnis saat ini (as-is) dan usulan proses bisnis (to-be) yang menjadi acuan untuk mengidentifikasi aktor, kebutuhan pengguna, fitur, dan kebutuhan fungsional sistem sehingga use case dapat dimodelkan. Penelitian ini juga menghasilkan rancangan sistem yang terdiri dari class analysis, activity diagram, sequence diagram, Logical Data Model, Physical Data Model, dan rancangan antarmuka. Hasil analisis dan perancangan tersebut kemudian dievaluasi, evaluasi menggunakan Traceability Matrix menghasilkan kesimpulan bahwa seluruh fitur pada sistem telah memenuhi kebutuhan pengguna, seluruh kebutuhan fungsional sistem berasal dari fitur pada sistem, use case telah didefinisikan sesuai dengan fitur pada sistem, dan use case dapat ditelusuri ke activity diagram dan sequence diagram, sedangkan evaluasi menggunakan System Usability Scale (SUS) menghasilkan skor 76,4 atau nilai “C” menurut grade scale, “good” menurut adjective scales, dan “acceptable” menurut acceptability ranges sehingga dapat diartikan bahwa perancangan Sistem Informasi Audit Internal memiliki usability yang baik dan dapat diterima oleh pengguna.
English Abstract
PT Wijaya Karya Beton Tbk is one of subsidiaries of PT Wijaya Karya (persero) Tbk, which is engaged in precast concrete industry. PT Wijaya Karya Beton Tbk conducts an internal audit to evaluate company performance. Internal audits of PT Wijaya Karya Beton Tbk are still carried out conventionally, causing problems such as paper waste, inefficient time in completing a process, and delays in sending audit reports and RTP reports. From the existing problems, this research is conducted with the aim to analyze and design an information system that will be able to facilitate the implementation of internal audits. The method used in this research is the Waterfall model. At the requirements analysis stage, discussions, interviews, and documentation studies are executed with the QSHE & SM Bureau to explore the requirements, then at the system design stage, the design is carried out based on the requirements analysis and carried out with an object oriented approach. After the analysis and design is complete, an evaluation of the results of the analysis and design is carried out. This research results in modelling the current business process (as-is) and proposed business processes (to-be) which serve as a reference for identifying actors, user requirements, and functional requirements of the system so that the use case can be modelled. This research also produces a system design consisting of class analysis, activity diagrams, sequence diagrams, Logical Data Model, Physical Data Model, and interface design. The results of the analysis and design are then evaluated, in which the evaluation using the Traceability Matrix concludes that all features on the system meet user requirements, all functional requirements of the system come from features on the system, use cases have been defined in accordance with the features of the system, and use cases can be traced to activity diagrams and sequence diagrams, whereas the evaluation using System Usability Scale (SUS) produces a score of 76.4 or “C” value according to grade scale, "good" according to adjective scales, and "acceptable" according to acceptability ranges so that it can be interpreted that the design of the Internal Audit Information System has good usability and can be accepted by the users
