Pada minimarket, produk merupakan bahan pokok yang dijual belikan. Produk di minimarket terdapat antara produk yang laku dengan produk yang tidak laku. Dengan adanya masalah ini, perlu untuk menciptakan sistem yang dapat mengelompokkan produk laku dan produk yang tidak laku, yang dilakukan di Minimarket MM.TIKA Bengkulu dan dilaksanakan pada bulan Juni sampai Juli 2015. Algoritma K-Means tidak terpengaruh terhadap urutan objek yang digunakan, hal ini dibuktikan ketika penulis mencoba menentukan secara acak titik awal pusat cluster dari salah satu objek pada permulaan perhitungan. Jumlah keanggotaan cluster yang dihasilkan berjumlah sama ketika menggunakan objek yang lain sebagai titik awal pusat cluster tersebut. Namun, hal ini hanya berpengaruh pada jumlah iterasi yang dilakukan. Tujuan untuk membuat aplikasi dan menganalisis penjualan produk pada swalayan MM.TIKA Kota Bengkulu menggunakan metode K-Means. Dengan adanya sistem ini dapat memberikan manfaat kemudahan untuk menganalisis pengelompokkan penjualan produk pada swalayan MM.TIKA Kota Bengkulu, menentukan dan mengklasifikasikan penjualan produk yang laku dan kurang laku. Algoritma K-Means Cluster Analysis pada dasarnya dapat diterapkan pada permasalahan dalam memahami perilaku konsumen, mengidentifikasi peluang produk baru dipasaran dan algoritma K-Means ini juga dapat digunakan untuk meringkas objek dari jumlah besar sehingga lebih memudahkan untuk mendiskripsikan sifat-sifat atau karakteristik dari masing-masing kelompok. Metode yang digunakan pengumpulan data adalah observasi dan wawancara. Dengan adanya aplikasi ini, pemilik minimarket dapat melihat hasil pengelompokkan produk yang laku dan tidak laku. Maka, bila terdapat produk yang tidak laku, pemilik minimarket dapat mencari alternative lain agar produk yang tidak laku dapat menjadi laku. Kata Kunci : K-Means, Clustering, Data Mining, Produk
This research aims to create a program to help facilitate the school in determining the students who are eligible for a scholarship. SMA Muhammadiyah 4 Kota Bengkulu serve as research place. The selection process of scholarship recipients in SMA Muhammadiyah 4 Kota Bengkulu is equipped with various criteria, such as family economy, family dependent, child status, School Achievement, out-of-school education and discipline. It should be noted in the assessment of the criteria and must be relevant because it will basically affect the outcome. In making this Program we use Visual Basic 6.0 software and apply SMARTER Inference Forward Chaining method. The results obtained from this study, have met the criteria desired by the SMA Muhammadiyah 4 Kota Bengkulu and the use of this method is considered effective to be used to anticipate the similarity of the ranking. So that the selection process of scholarship recipients in SMA Muhammadiyah 4 Bengkulu City on target.Keyword : Decision support system, Simple Multi-Atribute Rating Technique Exploiting Rank (SMARTER), Forward Chaining
Technological developments are increasing very fast along withcurrent development. It encourages every human being, especially tatabusiness as a provider of information to continuously follow developments and make decisions to improve,develop, and update any information presented to provide good service. The general section is part of the institution that is authorized to handle documents andfiling. In the General Section, verything related to archiving documents is archived and updated. The use of Microsoft Excel to handle documents in the General Section raises obstacles which include difficulties in searching for old data, formats in the documentation process that are still inconsistent, and difficulty knowing which documents will be processed. Therefore the researchers conducted this research aiming to produce an application that is able to manage document data so that managing document data is easier. From the research that the writer is doing, it will produce an application using the PHP programming language and SQL Server as the database, where the user of the application is the user. With this application, it can help users in the process of documenting, filing, and preparing document reports. The application can also be a solution in managing, storing, and archiving documents.
Academic activities are daily operational activities that occur in an educational institution, especially in universities. Academic activities must be carried out by students and lecturers. Within the scope of academic activities at the Faculty of Engineering, University of Muhammadiyah Bengkulu, the media used to convey information on the current academic schedule no longer uses bulletin boards but uses social media, namely whatsapp. Although academic activities are routine, it is still common for students and lecturers to forget the schedule of academic activities. To overcome this, the Faculty of Engineering requires a personal digital assistant application (virtual assistant) as an accurate, efficient and portable reminder. The virtual assistant application that is built consists of two platforms. First, the mobile platform used by lecturers and students to view some academic agenda information and receive real-time information/announcements and notifications/alarms related to academic activities. Second, the web platform used by the Administration to broadcast announcements or invitations to mobile application users. Based on the test results, the virtual assistant application can run on two platforms.
The development of technology is currently growing very rapidly which allows us to access various kinds of data and information, but there are lots of people who abuse this ability, for example phishing activities that often target data and information owned by individuals and companies. Loss of data and information is very detrimental to individuals and companies, where the data and information can be used as a tool for extortion, used as a fraud tool and even the information can be traded. The main reason for the importance of maintaining the security of information is to protect information from online crimes. One of the techniques designed to protect important and confidential information is a cryptographic technique using the Blowfish algorithm and also a QR Code which functions as second line security. where data and information that has been converted into a QR Code cannot be changed. The purpose of this study is to apply the Blowfish Algorithm for Encryption and Decryption of the QR Code into an android-based application system. The results of this study are: The blowfish algorithm can be implemented into an android-based application. Plaintext which is converted into ciphertext using the blowfish algorithm can be used as a QR Code using a QR Code generator. A QR code is up to 7089 numeric digits and 4296 alphanumeric characters. The amount of information will affect the QR Code module, so the symbols in the QR Code will become more complicated. This application has received an assessment from respondents from users with an average value (6.5) with the category of choice "agree".
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
