In the daily use of technology, humans cannot be separated from the internet as a need to exchange information. People at this time spend more time in front of computer screens, laptops, even smartphones to find out information, send data to some of their friends. One of the information that is often sought or sent is a file. Apart from that, image files are files that are much searched for and sent, and many also contain important information in them. Image file security is of course very important so that unauthorized parties do not hack or manipulate information from the image. There is a way to secure information so that it does not leak to unauthorized parties, namely by using cryptography and steganography. By combining these two methods, you can maintain the confidentiality and security of a file, especially image files. In this study the algorithm and method used is the AES cryptographic algorithm (Advanced Encryption Standard) 256 and the LSB (Least Significant Bit) steganography method. Data integrity needs to be tested to ensure that the encryption and decryption processes are running properly. Data integrity testing uses the SHA-1 method. Likewise, the image quality after insertion will experience a decrease in quality. To evaluate this, it is necessary to test using the PSNR method. From the results of data integrity testing by comparing the hash value of the decrypted image file with the original image file, there is no difference. So this shows that the encryption and decryption process was successful. While in testing using the PSNR method, the average PSNR value is 44.14086 dB and with an average error value of 2.830403 dB, which means there is a small decrease in quality. From the implementation and testing results, it can be concluded that the AES 256 cryptographic algorithm and the steganography method LSB can be implemented in maintaining the confidentiality and security of secret messages.    

The aim of this study is to design a production accounting information system for the determination of the cost of production that can help the SMEs Jepara carving in the determination of the cost of a product exactly. Information on the cost of a product is very important as a basis in determining the selling price of a product. so far the SMEs Jepara carving in determining the cost of a product is done by estimating the costs of production and often do not include a production cost that nominal little cost. So the cost of production does not reflect actual cost consumption. This can certainly cause the production cost to be undercost or uppercost. The approach in determining the cost of production using the method of ativity-based costing, activity-based costing method is the determination of the cost of a product based on activity. Research methods that Research method using Reseach and Development (R&D) method with prototype system development model. This study was conducted on SMEs carving Jepara. The result of this research is in the form of accounting information system product for determination of cost of production at SME Jepara carving which can assist in determination of cost of product. Implementation of the activity-based costing method as an approach in determining the cost of products is able to provide benefits that the charging over the cost can be more precise. Efficiency in costs can be obtained. The use of activity based costing method can also decrease the selling price of the product, so that Jepara carving SMEs will be better able to compete both for domestic market and international market.

Comput At this time in Buaran Subdistrict, Pekalongan District, there are many obstacles, one of which is the recording of cash receipts and disbursements which are very piling up because moreover in the implementation, it is still for manual recording, one of which is by means of counting, still using handwriting. Cash book, if you want to print financial statements and still use a lot of Microsoft Excel as data storage and printing a report, it takes too long for information system data to be a lot of completion data is not timely and makes it less efficient.
