Skincare is a procedure or steps for skin care that is carried out using skincare products and beauty cosmetics with ingredients that are safe and well used according to the skin type of each individual face. Before doing skincare the most important thing is to know the type of skin on each of our faces.In the process of designing decision support system applications the selection of skincare according to facial skin type uses fuzzy logic. This research was chosen because it was able to select the best alternative from a number of alternatives. In this case the intended alternative is selected facial foam products based on the specified criteria. This decision support system can provide an alternative decision on selected products that can later be used as a reference to determine the product that suits the type of facial skin. Applications are made using Basic For Android (B4A), with Basic programming languages, and software support tools such as Paint and Photoshop. The design of this application is the best solution to solve problems that exist on facial skin.This application is expected to be more effective, especially in terms of making decisions.

AbstrakToko GOC Kosmetik adalah sebuah toko yang menjual berbagai macam merk kosmetik yang saat ini ramai dengan pelanggan. Begitu banyak transaksi yang dilakukan setiap harinya mengakibatkan penumpukan data transaksi. Toko GOC mempunyai beberapa masalah seperti rumitnya mengetahui produk (item) yang sering terjual sehingga toko GOC Kosmetik tidak dapat mengetahui kosmetik apa saja yang sudah tidak memiliki persediaan lagi. Sehingga penulis data transaksi  dapat diolah dengan menggunakan data mining agar dapat mengolah pengetahuan-pengetahuan data dalam skala besar secara efisien dan efektif. Dan menggunakan algoritma apriori sebagai metode yang melihat keterkaitan hubungan antar elemen. Untuk mengetahui hubungan item set apa saja yang terjadi pada proses transaksi dengan menggunakan algoritma apriori merupakan algoritma yang pertaman kali digunakan ketika melakukan proses asosiasi. Hasil Penelitian ini menunjukan bahwa bila membeli SS hingga hendak membeli KN dengan nilai support 69% serta nilai confidance 88% sehingga data ini bisa berikan saran kepada pihak toko buat tingkatkan produk serta lebih tingkatkan strategi penjualan produk buat menggapai nilai keuntungan yang besar. Kata kunci: Data Minning, Algoritma Apriori, Support, Confidence  Abstract  GOC Cosmetics Store is a shop that sells various cosmetic brands that are currently busy with customers.

Clustering is a method of dividing datasets into several groups that have similarity or the same characteristics. High-dimensional Datasets will influence the effectiveness of the grouping process. This study compares two dimension reduction algorithms, namely Principal Component Analysis (PCA) and Singular Value Decomposition (SVD) using K-Means clustering method to find out the best algorithm with the smallest Bouldin Davies Index evaluation. The dataset of this study involved public data from UCIMachine Learning which contains the number of weekly sales of a product. Data processing is performed by comparing the number of clusters from 3 to 10 and the dimension reduction from 2 to 10. From the data processing the RapidMiner tools, application with dimension reduction can provide better results than without dimension reduction. In particular, the PCA algorithm shows better results than the SVD, with which the best number of clusters is 5, and the number of dimensional reductions is 3 with a Bouldin Index of 0.376.
