Abstract

The use of technology in the application of Customer Relationship Management (CRM) becomes very important to build relationships between customers as well as providing information provided to customers. The benefits of implementing CRM are to help keep existing customers and to gain new customers. In this study the authors implement CRM in an information system E-commers on Bookstore Gapura. Where currently there is no E-commission information system available in Gapura Bookstore. The method used in this design is using Data Flow Diagram (DFD). This application is also created by using PHP programming language using MySQL. With this application so that facilitate Bookstore Gapura in providing information and promotion, so that information delivered more efficient and clear to the consumer.

Abstract

Mustard vegetables are classified as leaf vegetables from the Cruciferaefamily which have high economic value and are very popular among the people. Mustard vegetables are often used by people as processed ingredients in various types of cuisine. In general, Vegetable Vegetables are planted in the lowlands to the highlands and harvest is done at the age of 30 - 60 days after planting, depending on the variety. Expert systems are systems that try to adopt human knowledge to computers, so that computers can solve problems as usual by experts. Bayes method is one of the methods found in expert systems that can calculate or process the probability values of each symptom. The expert system detects mustard plant disease has 5 types of diseases found in mustard vegetable plants, namely seedlings, leaf rot, clubroot, leaf spot, alternaria rot.

Abstract

The limitations of humans to maintain the security and confidentiality of stored data can have a bad impact if it is used by unauthorized parties. One way to secure shipping is to convert data into one that is not understood by encoding and insertion using cryptographic techniques. Cryptography is the study of system security, where the system needs to be secured from interference or threats from irresponsible parties. One of the cryptographic algorithms is the Blowfish Algorithm. The Blowfish algorithm is a modern cryptographic algorithm symmetrical key shaped block cipher. The Blowfish algorithm is quite simple but strong enough because it has a long key space, making it difficult to attack. Encryption is done by using a certain key, so as to produce ciphertext (files that have been encrypted or encoded) that cannot be read or understood. The ciphertext can be restored as if it was decrypted using the same key when encrypting the file. The key length used can affect the security of the algorithm. The decryption flow is almost the same as the Blowfish Algorithm encryption, except in the P-array (P1, P2, …… .., P18) done by invading. Information of a system is certainly stored in a database that is always possible to attack, but using cryptography then the problem can be overcome. By using the Blowfish algorithm, information security in a MySQL database can be improved.

Abstract

Information technology has penetrated into various fields including educational institutions, then the need for information is currently increasing. Currently everyone needs information in a fast, short and accurate time, therefore it takes media and tools that can support the work with various applications, media, and easy ways to access the information, one of them is internet connection with hotspot service or wireless-based computer network (WiFi). SMA PGRI Aikmel is one of the private schools that have many enthusiasts because it has adequate facilities in conducting teaching and learning process. Along with the increase of public trust to this educational institution, hence required a wireless based computer network to support performance at academic part and to improve teaching and learning activity. By leveraging rapid technological advancements to enable equipment using cable technology to be replaced with wireless technology such as radio frequency media. This research is a qualitative research. Data were collected by observation, interview, documentation, and literature study. With the Network Development Live Cycle (NDLC) method, this study examines the development of wireless networks using Mikrotik devices and cisco packet tracer applications as simulation media from the development of network schemes.

Abstract

In order to increase customer satisfaction at Deli Serdang SME Corner, a study was conducted on the level of customer satisfaction in Deli Serdang SME Corner. To find out the extent to which UKM UKM's capabilities provide satisfaction through product, service, financial, shipping and company conditions, marketing research information from the results of marketing research is needed to find out the attitudes and behavior of customers towards what is most influential in making decisions at SME Corner customers Office of Cooperatives, Small and Medium Enterprises in Deli Serdang Regency. This research starts from the stage of analyzing existing systems that are obtained from direct interviews with related parties and observations. While the design method uses the Unified Modeling language (UML) to describe system design. In this case, to calculate the level of customer satisfaction, the AHP (Analytical Hierarchy Process) method is used. Using a decision-making system can provide convenience for Deli Serdang's UKM Corner to determine customer satisfaction in improving the quality to determine the level of customer satisfaction that is applied using PHP and MySQL Database programming .. The system was developed using a software engineering approach, including analysis, design and implementation . At the analysis stage, process analysis, input analysis, output analysis, ongoing system weakness analysis and needs analysis are carried out.

Abstract

Palang Merah Indonesia (PMI) is an independent and neutral organization in Indonesia whose activities are in the social field of humanity. PMI Medan City is overwhelmed by managing data on blood receipts from various places, this causes delays in information that should be informed to the public, the delay in disseminating information about blood stocks can have an impact on the difficulty of getting information on certain types of blood needs. The blood supply in PMI will later be distributed to the hospital. Many hospitals often have difficulty getting information or lack of public knowledge about how to obtain information about the availability of blood stock at PMI. Therefore we need an information system that can provide information quickly, well and accurately. To overcome this, a system will be developed that uses the concept of Supply Chain Management to control the blood supply in PMI. This system can control the blood donation process both during donation, the donation process, and finally for whom the blood is donated so that the blood stock information process can be maintained and will not lack.
