Transaksi penjualan merupakan suatu usaha penjualan yang dilakukan setiap menit, setiap hari, setiap minggu bahkan bertahun-tahun. Sehingga data akan semakin menumpuk bisa berasal dari proses manual maupun proses komputasi. Sehingga data yang ada belum dimanfaatkan dengan baik oleh pengambil keputusan. Tulisan ini bertujuan untuk memberikan laporan hasil penelitian mengenai implementasi algoritma apriori untuk analisis penjualan. Penelitian ini didukung dengan metodologi pengembangan perangkat lunak yang disebut linear incremental development. Pada proses yang dilakukan pada implementasi perangkat lunak ini terdapat beberapa langkah seperti penentuan masalah, identifikasi dan penyelesaian resiko, pengembangan dan test, serta perencanaan siklus berikutnya. Setiap langkah pada tahapan tersebut digunakan untuk memetakan permasalahan yang ada hingga terbentuknya suatu aplikasi sesuai kebutuhan. Sebagai hasil dari penelitian ini adalah aplikasi berdasarkan algoritma apriori yang terdiri dari pemilihan Itemset dan aturan asosiasi. Keluaran dari perangkat lunak ini digunakan untuk data acuan stok barang serta mengotomatisasi perhitungan analisis penjualan barang. Kata kunci: sequential linear incremental, algoritma apriori, penjualan, implementasi.

Ranking of an activity is very important to support work effectiveness. Previous works, ranking for distribution product is used by manual process or averaging value. Problem in this research, the research should be found the effective way to rank the distribution product. This research proposes assist the ranking with a computational model based on Fuzzy Multiple Decision Making (FMADM). Getting an effective ranking, a variable in FMADM computing is required. Variables is used in this research such as number of households, number of small-scale enterprises run by households, gross domestic regional income, and economic growth rate of a region. Research completion is assisted by using self-built research methods. Research method consists of determining value of origin, determining degree of membership, determining weight of each variable, calculation of relation matrix, calculation of the preference value in each village for ranking value, and last is sorting. Operationalized FMADM is gain a result with three priorities district. Priority number one is all of district that have a rank or Vij (alternative rank) higher than 0.4. It means only 7% or 5 villages with the highest rank. Priority number second s all of district that have rank between Vij = 0.26 and Vij = 0.4. It means only 62% or 44 villages. Priority number three is district that have a rank lower than Vij = 0.26, and only 31% or 22 villages. Impact in use of FMADM, calculated in rank, is the process runs effective and dynamic with changing of weighted. User can arrange of weighted as needed.

The transaction process in business is an important factor that must be maintained for a business increase. This activity can be maintained by computerized. Application of computer which help process business transactions is an important thing that should be provided. This research aims to provide a system that helps routine transaction in daily food sales. Transaction in this system has included activities such as ordering, fulfil orders, payment, recording, financing, and reporting to management. Implementation of the system, that have used a prototype system development method. At each stage of the prototype is assisted by object-oriented programming, namely UML (Unified Modelling Language). Use of UML diagrams includes use case diagrams, activity diagrams, sequence diagrams, class diagrams, and deployment diagrams. The results of this research are web technology-based transaction systems. The system has included order, delivery of an order, payment, order recording, and financial reporting for management. The system is made for the implementation of five main business processes that help the transaction system. The main business processes, that have created, is consisted of services, order, fulfil orders, financial services, and report for management.
