Abstract

Salah satu teknik dalam Data Mining yaitu clustering. Clustering adalah pengelompokan sejumlah data atau objek ke dalam cluster (group) sehingga setiap dalam cluster tersebut akan berisi data yang semirip mungkin dan berbeda dengan objek dalam cluster yang lainnya. K-means mempunyai kemampuan mengelompokkan data dalam jumlah yang cukup besar dengan waktu komputasi yang relatif cepat dan efisien. Namun, K-means mempunyai mempunyai kelemahan yang diakibatkan oleh penentuan pusat awal cluster. Hasil cluster yang terbentuk dari metode K-means ini sangatlah tergantung pada inisiasi nilai pusat awal cluster yang diberikan.Ini menyebabkan hasil clusternya berupa solusi yang sifatnya local optimal. Penelitian ini melakukan pencarian pusat cluster yang paling optimum berbasis Sum Of Squared Error (SSE), diharapkan pusat cluster yang diperoleh nantinya akan menghasilkan cluster - cluster, dimana antar anggota cluster memiliki tingkat kemiripan yang tinggi. Perbaikan performa cluster K-Means akan diterapkan pada Analisis Penilaian Online Customer Review dan Rating pada Online Marketplace.

Small and medium-sized enterprises or better known as SMEs. SMEs are developing very rapidly and have an important role for the economy. The main obstacle faced by SMEs actors is the difficulty of promoting products widely and this occurs in almost all SMEs, including Karo Regency SMEs, in terms of overcoming this, various strategies have been implemented by the Karo Regency Cooperative and SMEs services including: holding exhibitions in various regions, collaborating with third parties and provide business consulting services. However, these strategies are considered less effective because there are still many weaknesses such as the large costs required, limited SMEs that can participate, short time, and small scope of promotion. The purpose of this study is to develop aweb-based e-Marketplace system as a medium for promoting SMEs products widely and to increase income for SMEs players in Karo Regency.

Abstract

The Information System is very useful for PT BPR NBP 8 Tigalingga Branch because it can simplify and speed up work processes on the system. The previous system still used the manual method, namely recording data by writing in a book. At PT BPR this is very useful in carrying out its activities so it is very helpful for officers. This information system assists officers in storing financial reports, data, and with this system it can be easier or safer. In making database information system databases at BPR, it really needs an implementation process design. The database information system will be used to record information on lending services and financial payments at bpr nbp. The process of making a loan and payment information system will be designed using a Web Server application, XAMPP, Sublimenttext 3, Web Browser. Based on the analysis of the previous system, it was very common to have errors in bookkeeping and experienced many errors, so currently using an information system that has been designed that will help officers more easily, quickly, even more secure and will not experience errors again.

Abstract

Inventory of goods is goods available in a shop or trading company for sale and purchase to meet consumer demand. However, the inventory of goods must be checked periodically so that there is no stock shortage of the goods. This will make the form of service to consumers worse. So making decisions regarding stock of goods becomes difficult because information regarding the availability of goods is not provided quickly and accurately. The aim of this research is to answer the above problems that UD still faces. Minang Traditional Home Snacks. UD. Minang Traditional House Snacks is a trading business that sells various snacks. There is a need for a web-based application to be able to manage the supply of these snacks. The results and conclusions of this research are that this application can operate regarding purchases (incoming goods) and sales (outgoing goods) in providing this stock. This results in an inventory card containing information on purchase transactions, sales expenses and inventory in the form of a report that can be printed. With this application, it becomes easier for the owner to run his trading business, especially managing snack supplies, compared to not using the application.
