Abstract

Data mining is a method of searching for previously unknown information from a large database. The important information found to be valuable and beneficial for the making of a decision. The information gained should be precise and accurate because it was highly influential in decision making as well as the outcome of the decision, as was the information required by the Minimarket 212 Mart Taman Carina Batam. The minimarket is located close to the residents' housing and the school. Minimarket 212 Mart requires an analysis to find out consumer purchasing habits that would later be useful for organizing store layouts, make inventory of product efisien in order for sales transactions to run smoothly also increase sales results in minimarkets. Market basket analys methods can be used to analyze the interrelationship of product that consumers buy at the same time to find out the consumer's purchasing habits. The study successfully found the combination of interrelated products that had the highest support value and confidence value on the combination of Snack, Baverage, Breakfast Food which were to have a 26,7% support value and 100% confidence

Abstract

Increasing customer bandwidth needs to be considered by companies by determining potential customers. Potential determination is needed because previously it was only done randomly. Therefore, first determining the potential is needed by grouping customers who have the same characteristics based on the data and attributes they have. This research will implement data mining technique with clustering method with K-means algorithm on 263 FTTH Broadband customer groups. Then the potency can be determined based on the final centroid point in the grouping. The results obtained are divided into 5 clusters consisting of 34 customers or 12.92% of the total potential customers, 29 customers or 11.02% of the total potential customers, 56 customers or 21.30% of the total potential customers, 54 customers. or 20.53% of the total fewer potential customers and 90 customers or 34.22% of the total non-potential customers. Comparison of the validity of the Davies-Bouldin Index cluster for 5 groups between K-Means and K-Medoids, the value of 0.538 for K-Means and 0.819 for K-Medoids is obtained. This method is used to streamline the distribution of bandwidth.

Abstract

Persediaan merupakan hal yang penting bagi perusahaan untuk menjalankan proses bisnis agar efektif dan efisien sesuai dengan tujuan yang hendak dicapai. Salah satu contohnya adalah persediaan suku cadang pada PT. XYZ yang bergerak dibidang pabrikasi dan distribusi logam berat yaitu Cooper Slag di Kota Batam yang sangat dibutuhkan oleh pihak galangan kapal maupun Offshore. Tujuan dari penelitian ini adalah memudahkan PT. XYZ dalam mengambil keputusan optimasi persediaan suku cadang. Sistem yang di pakai adalah Fuzzy Inference System yang penerapannya menggunakan metode Mamdani. Metode ini dapat dengan mudah diterapkan pada sistem yang dibuat dengan bantuan toolbox fuzzy inference system. Fungsi implikasi yang digunakan dalam proses ini adalah fungsi MIN. Hasil yang didapat dalam pengujian FIS sebesar 8, angka ini masih dalam parameter variabel output sedikit dan sedang. Maka, didapat kesimpulan bahwa FIS metode Mamdani dapat membantu PT. XYZ dalam membuat keputusan pada optimasi dalam estimasi pengadaan suku cadang.
