Microfinance Institutions Agribusiness (LKMA) Prima Agung Kenagarian Sungai Duo Kecamatan Sitiung Kabupaten Dharmasraya is one form of cooperatives engaged in the field of micro-credit. In management, conventional systems are still used in the form of a book. This method is less effective for savings and loan transactions in large quantities because it required precision in processing accounting data such as repetition of writing that can lead to wastage of working time. With the existence of these problems, LKMA Prima Agung needs to use a savings and loan applications that can assist in data processing. The research method used in this study is the identification of the problem, literature, and the establishment of data collection, system design, analysis, design and implementation of the system. The results of this study are expected to be an alternative solution, especially for LKMA Prima Agung in completing various transaction processes effectively and efficiently.

Electronically data interchange between institutions or companies must be supported with appropriate data storage media capacity. MySQL is a database engine that is used to perform data storage in the form of information, where the data can be utilized as needed. MYSQL has the advantage of which is to provide convenience in terms of usage, and able to work on different platforms. System requirements that must be reliable and multitasking capable of making the database not only as a data storage medium, but can also be utilized as a means of data exchange. Dropbox API is the best solution that can be utilized as a technology that supports the database to be able to Exchange data. The combination of the Dropbox API and database can be used as a very cheap solution for small companies to implement data exchange, because it only requires a relatively small Internet connection.

Electronic mail is a communication model that is fundamental in the era of globalization. Proven on any form of registration data or information requires the presence of email address(electronic mail). The use of email itself cannot be separated from the abuse (such as stelling password and mail spoofing) from some parties so it needs security form in email communication. Communication security on mail server such as ZIMBRA mail server has been well-implemented, such as the use of ssl certificate. But the security is still standard. So, when user and password have been found out by third party, email content will be read easily (in cryptography technique it is called plaintext reading). On research that was conducted with pretty good privacy (PGP) method email communication security was focused on the email content by encrypting mail text along with the attachment file. In a study conducted, using the mail engine Zimbra mail server. Result of research shows that PGP security is able to secure email content whether the text or the attachment, showing difference of attachment file size is bigger on PGP using and change mail header from the standard mail.

Perencanaan Search Engine E-commerce dengan Metode Latent Semantic Indexing Berbasis Multiplatform Ni Made Ari Lestari; Made Sudarma

E-commerce is a sale and purchase transactions that occur through electronic systems such as the Internet, WWW, or other computer networks. E-commerce involves electronic data interchange and automated data collection systems. In all e-commerce search engine provided a column for the search items desired by the user. In e-commerce such as Tokopedia, Lazada, MatahariMall, Amazon, and other search engines that provided just use a regular search engine technology. In the usual search engines getting longer sentences from the input or output of goods search results will be more extensive and more. However, by utilizing the semantic indexing technology, the longer and clear input desired goods, the number of searches will be few and accurately in accordance with the input that helps the user in decision making. In this study discussed how to build a search engine on the web e-commerce by using Latent Semantic Indexing. The first starts from the use of Text Mining methods for word processing, and the method Levenshtein Distance to repair automatic word and the last Latent Semantic Indexing for information processing and input expenditure.

The hassle of analytical and numerical solution for liquefaction modeling, repetitive laboratory testing and expensive field observations, have opened opportunities to develop simple, practical, inexpensive and valid prediction of wave-induced liquefaction. In this study, Artificial Neural Network (ANN) regression modeling is used to predict the depth of liquefaction. Despite of using Back Propagation (BP) to train ANN, a modified Genetic Algorithm (called as Wide GA, WGA) is used as ANN training method to improve ANN prediction accuracy and to overcome BP weaknesses such as premature convergence and local optimum. WGA also aim to avoid conventional GA weaknesses such as low population diversity and narrow search coverage. Key WGA operations are Wide Tournament Selection, Multi-Parent BLX-? Crossover, Aggregate Mate Pool Mutation and Direct Fresh Mutation-Crossover. ANN prediction accuracy measured by Median APE (MdAPE). Global optimum solution of WGA is best ANN connections weights configuration with smallest MdAPE.

Information technology is the result of a human mind to develop ordinances or specific systems and use them to solve problems in life. Submission of information today is no longer through the print media, but will gradually shift to the use of digital electronic media. The announcement can be interpreted as a message delivered to every person who is the target destination or destination information. This study discusses the announcement of information systems that can replace conventional media announcements still. With this information system of this announcement makes any lecturer and secretariat in one program studi in College X no longer need to print and posting notices on board the information available, but may be digital by entering the announcement into the system to afterwards the announcement will be displayed on each screen television or monitor the spread and available in every area of ??the campus. This can make the process of delivering information to become more effective and efisien if compared to the print media.
