Abstract

Out of all business company process using technology and one of them is inventory. By combining the process of inventory company business with technology, it will make a great contribution to the company itself. Which is one of the benefits is the managerial in the inventory management of the company. In the meant time, the company who use this inventory method by replacing the old and traditional one with the new one integrated with the information system, will reach the maximal effort of working in the company and will save a lot of time in terms of managing the inventory of company. Comparing between the two systems of the company, the old one and the new integrated one, of course the most updated one will be good and be implemented in almost all of the company in the world The change in the company system was conducted on PT. Nusa Sukses Jaya. The changes include replacing the system with the new one integrated by information system in order to answer the challenge of growing technology in the modern age.  Key wordsPerusahaan, the old system, the new integrated system, inventory

Abstract

Salah satu material yang bersifat feroelektrik adalah oksida logam Aurivillius. Pada penelitian ini, dilakukan sintesis oksida logam Aurivillius SrBi4Ti4O15 menggunakan metode hidrotermal selama 72 jam, konsentrasi NaOH 3 M sebagai mineralizer, dan variasi suhu 200°C, 220°C, dan 240°C. Hasil sintesis dikarakterisasi dengan difraksi sinar-X dan didapatkan bahwa suhu sintesis 240°C menghasilkan senyawa berfasa tunggal dengan sistem kristal ortorombik, grup ruang A21am, dan parameter sel satuan a = 5,5396 Å, b = 5,5800 Å, c = 40,9734 Å. Senyawa ini memiliki tingkat kristalinitas lebih bagus dan yang lebih tinggi daripada oksida logam sejenis yang dihasilkan dengan metode reaksi kimia fasa padat. Sifat feroelektrik menunjukan nilai polarisasi remanen Pr(+) 35,10 Ccm-2, Pr(-) 24,10 Ccm-2. Kata kunci: sintesis, oksida logam, Aurivillius, hidrotermal
