Much of the work reported in the literature on cellulose acetate reverse osmosis membranes has raised new and important questions with regard to the dense or “active” layer of these membranes. Several thickness values and structures have been attributed to the dense layer. To ensure the correct interpretation of the cellulose acetate structure thirteen different preparative techniques have been used in this investigation. These thirteen methods included various combinations of water substitution, freeze drying, freeze sectioning, fracturing, embedding, and microtomy techniques with both transmission and scanning electron microscope observations.It was observed that several factors can cause a distortion of the structure during sample preparation. The most obvious problem of water removal can cause swelling, shrinking, and folds. Improper removal of embedding materials, when used, can cause a loss of electron image contrast and, or structure which could hinder interpretation.

Sales that go so far encounter obstacles in the process of marketing from consumers to consumers, the sale of goods still use a system of sales in the form of book-shaped catalogs, very tight competition, locations adjacent to other printing, and constraints from distance and time to obtain information on shopping in printing . It makes the sale less cost saving, energy and time because the system used still manually. The method used in the design of information systems sales of goods is waterfall method. From the manufacture of web-based goods sales system, is expected to solve the existing constraints, simplify, accelerate the sales system and hopefully can increase profits on the sale of goods Rahayu Bekasi Printing.   Keywords: Goods, Information, Sales, Printing, Waterfall.                                                                   Abstrak                                                                  Percetakan Rahayu merupakan sebuah badan usaha yang menyediakan jasa penjualan barang seperti undangan pernikahan, undangan khitanan, kartu nama, nota, kop surat, yasin dan lain-lain. Berdasarkan hasil penjualan yang telah dicapai selama ini, Percetakan Rahayu merasa belum puas dengan hasil yang didapat dan berupaya ingin meningkatkan penjualan serta pelayanan melalui sistem penjualan secara online. Penjualan yang berlangsung selama ini menemui kendala dalam proses pemasaran dari konsumen ke konsumen, penjualan barang masih menggunakan sistem penjualan berupa katalog berbentuk buku, persaingan yang sangat ketat, lokasi yang berdekatan dengan percetakan lainnya, serta kendala dari jarak dan waktu untuk mendapatkan informasi belanja di percetakan. Hal tersebut membuat penjualan kurang menghemat biaya, tenaga dan waktu karena sistem yang digunakan masih secara manual. Metode yang digunakan pada perancangan sistem informasi penjualan barang tersebut adalah metode waterfall. Dari pembuatan sistem penjualan barang berbasis web, diharapkan dapat memecahkan kendala yang ada, mempermudah, mempercepat sistem penjualan dan semoga dapat meningkatkan keuntungan penjualan barang pada Percetakan Rahayu Bekasi.   Kata kunci: Barang, Informasi, Penjualan, Percetakan, Waterfall.
