Abstract

Perpustakaan Universitas Kristen Petra yang berperan sebagai pusat layanan informasi bagi sivitas akademika tidak dapat lepas dari pengaruh teknologi informasi (TI). Untuk memastikan kelangsungan pelayanan informasi maka dibutuhkan sistem keamanan, pengelolaan data, pengelolaan masalah, dan pengelolaan lingkungan fisik yang memadai baik dari segi hardware maupun software. Ketergantungan ini mengakibatkan TI menjadi titik yang paling rawan dalam memastikan kelangsungan pelayanan informasi di perpustakaan. Dalam memastikan sejauh mana dukungan TI terhadap proses bisnis perpustakaan maka perlu diketahui seberapa baikkah kualitas layanan TI. Untuk mengukur kualitas layanan TI di perpustakaan dibutuhkan suatu proses audit.Pada penelitian ini, dilakukan proses audit operasional untuk mengumpulkan data guna menunjang penilaian audit. Pedoman yang digunakan dalam mengukur aspek – aspek tingkat kedewasaan TI ialah COBIT 4.0 pada bagian delivery and support 4, 5, 10, 11, dan 12 yang terdiri dari pemastian kelangsungan layanan TI, pengelolaan sistem keamanan, pengelolaan masalah, pengelolaan data, dan pengelolaan lingkungan fisik di perpustakaan.Penelitian ini menghasilkan temuan dan nilai tingkat kematangan TI di perpustakaan. Proses audit membantu perpustakaan dalam mengevaluasi kinerja layanan TI dan memberi masukan untuk perbaikan.

Abstract

PD. X merupakan perusahaan yang memproduksi biji plastik, yaitu mengolah sampah plastik bekas menjadi biji plastik. Semua pencatatan terkait pembelian bahan baku, penjualan, dan persediaan dicatat secara manual. Dalam menentukan harga pokok produksi, terkadang owner melakukan perhitungan berdasarkan estimasi harga pokok produksi atau terkadang melakukan perhitungan dengan menggunakan Microsoft Excel. Apabila melakukan perkiraan, owner kadang tidak terlalu memperhatikan biaya overhead. Perhitungan harga pokok produksi secara akurat merupakan hal yang penting karena hal ini membantu perusahaan untuk memastikan harga jual yang telah ditetapkan dengan menutup semua biaya yang digunakan. Perhitungan secara manual tentunya dapat meningkatkan kemungkinan perhitungan harga pokok produksi yang tidak akurat.Berdasarkan latar belakang permasalahan tersebut, maka dirancang sebuah aplikasi untuk melakukan perhitungan Harga Pokok Produksi dengan menggunakan metode Job Costing. Hasil yang diperoleh dari aplikasi yang telah dibuat, yaitu 66,67% user menilai baik dari segi desain interface aplikasi, 66,67% user menilai baik dari segi kemudahan dalam pemakaian aplikasi, 66,67% user menilai baik dari segi kelengkapan informasi yang dibutuhkan perusahaan, 100% user menilai baik dari segi keakuratan informasi dan data, dan 100% user menilai baik dari segi kesesuaian program dengan kebutuhan perusahaan.

In this application, there are also tests made, so the user can remember about the material that has been provided. This application is created using Adobe Flash CS6 and actionscript 3 as a programming language. Based on the results of testing of the applications and questionnaires, applications can be run by fully and strongly supports the process of understanding the historical material. This application adds to the interest in learning from the user, because of the interesting animation, and easy to use application. Users who doesn’t read narrative and do the applications in haste would have some difficulties to obtain a good final score.
