Abstrak
Sistem merupakan aspek yang penting dalam menjaga kelangsungan sebuah
perusahaan. Analisa dan perancangan sistem informasi persediaan dan pembelian ini
bertujuan untuk mencari kelemahan sistem dan memberikan solusi terbaik atas kelemahan
sistem itu. Maka dirasa perlu untuk adanya suatu sistem informasi persediaan dan
pembelian yang tepat di PT. Noorumi Catur Manunggal agar dengan terbangunnya sistem
informasi , informasi yang dihasilkan akan lebih cepat dan akurat.
Penulisan skripisi ini menggunakan metode analisis dan perancangan. Analisis
permasalahan dilakukan dengan cara melakukan survei terhadap sistem yang berjalan,
analisis terhadap temuan survei, identifikasi kebutuhan sistem informasi yang dibutuhkan
perusahaan dan identifikasi persyaratan sistem. Analisis dan perancangan sistem
dilakukan dengan menggunakan konsep Object Oriented Analysis and Design (OOA&D)
yang digambarkan dengan menggunakan notasi Unified Modelling Language (UML).
Hasil penelitian menunjukkan bahwa sistem persediaan dan pembelian yang
berjalan di perusahaan masih belum memadai dan informasi yang berjalan belum cepat
dan akurat. Perancangan sistem informasi persediaan dan pembelian akan memperbaiki
sistem yang sedang berjalan dan dapat mempercepat aliran informasi yang cepat dan
akurat dalam perusahaan.
Kata Kunci : Sistem Informasi, OOA&D, UML, Persediaan, Pembelian

perusahaan. Analisa dan perancangan sistem informasi persediaan dan pembelian ini
bertujuan untuk mencari kelemahan sistem dan memberikan solusi terbaik atas kelemahan
sistem itu. Maka dirasa perlu untuk adanya suatu sistem informasi persediaan dan
pembelian yang tepat di PT. Noorumi Catur Manunggal agar dengan terbangunnya sistem
informasi , informasi yang dihasilkan akan lebih cepat dan akurat.
Penulisan skripisi ini menggunakan metode analisis dan perancangan. Analisis
permasalahan dilakukan dengan cara melakukan survei terhadap sistem yang berjalan,
analisis terhadap temuan survei, identifikasi kebutuhan sistem informasi yang dibutuhkan
perusahaan dan identifikasi persyaratan sistem. Analisis dan perancangan sistem
dilakukan dengan menggunakan konsep Object Oriented Analysis and Design (OOA&D)
yang digambarkan dengan menggunakan notasi Unified Modelling Language (UML).
Hasil penelitian menunjukkan bahwa sistem persediaan dan pembelian yang
berjalan di perusahaan masih belum memadai dan informasi yang berjalan belum cepat
dan akurat. Perancangan sistem informasi persediaan dan pembelian akan memperbaiki
sistem yang sedang berjalan dan dapat mempercepat aliran informasi yang cepat dan
akurat dalam perusahaan.
Kata Kunci : Sistem Informasi, OOA&D, UML, Persediaan, Pembelian
