Abstract

Sheshop is a business activity engaged in the field of hamper making services. Since the last 2 (two) years, sales transactions in Sheshop have been increasing, the transaction data is only used as a report and is not used to regulate business strategies. The transaction data should be used to see the attachment of each type of product purchased by the customer simultaneously. The amount of sales transaction data on Sheshop can be used as an analysis of customer behavior in making purchases of hampers at Sheshop. This study performs data analysis by implementing the Apriori algorithm method because this algorithm handles data mining processes quickly on large amounts of data, from the results of this study Sheshop can make decisions on what items need more inventory compared to other items by looking at the value confidence and support by using the RapidMiner application. The results of this study indicate that the association rule formed from 568 Sheshop sales data uses a minimum support value of 10% and a minimum confidence of 50% produces 6 (six) association rules with a confidence value of 58% to 75% with all rules having a positive correlation level. Based on the 6 (six) association rules obtained, 2 products are often purchased at the same time, namely the Koran and tasbih with a confidence value of 75%.

Abstract

Science ability is one of the students' potentials that can be developed and can be competed. Every student's potential in the field of science can be excelled and directed to become ability. Science Olympiad is a forum to show students' abilities so that every elementary school is expected to participate. Schools must, of course, determine prospective participants for the science olympiad, with the selection of potential students with predetermined assessment criteria. In this study, implementing decision support with fuzzy logic for the conversion of criteria values ??and the Profile Matching method in determining the ideal profile of prospective Olympic participants, each student's alternative value on the criteria is obtained by the difference in value with the ideal profile, the smaller the value of the GAP difference, it indicates the best alternative. The results showed that the results of fuzzy and profile decisions were the three best alternatives for students who participated in the science Olympics.

Abstract

Pemenuhan kebutuhan stok persediaan barang merupakan salah satu dari pilar utama proses bisnis yang rutin dilakukan pelaku bisnis secara umum. Peluang akan terjadinya kesalahan perhitungan yang dilakukan secara konvensional tanpa adanya sebuah analisis mendalam yang menyebabkan tidak akuratnya penentuan jumlah persediaan yang harus dipenuhi. Hasil penelitian menyajikan sebuah solusi dengan pendekatan Data Mining menggunakan teknik aturan asosiasi (association rule). Pendekatan data mining dibangun dengan menggunakan sebuah kerangka kerja pupuler data mining CRoss Industry Standard Process for Data Mining (CRISP-DM) yang dikerjakan dalam 6 tahapan yaitu Business Understanding, Data Understanding, Data Preparation, Modeling, Evaluation, dan Deployment. Sampel UMKM kota samarinda menjadi objek pada penelitian dengan menggunakan 1000 data dari riwayat transaksi penjualan dalam kurun waktu tertentu yang diidentifikasi dengan menjalankan algoritma Frequent Pattern Growth (FP-Growth) untuk memaksimalkan kinerja komputasi dalam proses ekstraksi pola item barang. Ekstraksi pola aturan dari dataset transaksi penjualan dilakukan dengan 9 kali percobaan dengan melakukan perubahan nilai support (S) dan confidence (C) dengan hasil percobaan trbaik menghasilkan 9 best rule dengan rentang nilai S sebesar 9% - 14% dan C sebesar 60% - 75% yang mencakup aturan 2-itemset dan 3-itemset. Masing-masing rule diterapkan uji lift yang menghasilkan rentang nilai 2.790 – 3.698 dengan rata-rata nilai lift sebesar 3.26, dimana setiap aturan memenuhi nilai minimum (lift > 1.00) yang menunjukkan setiap kombinasi aturan memiliki peluang cross-selling yang baik
