I. PENDAHULUANISNIS yang semakin berkembang bisa dipengaruhi banyak faktor seperti inovasi pada produk penjualan. Salah satu inovasi di bidang ritel adalah mencari asosiasi atau hubungan antar item produk sehingga dapat dipaketkan dan dijual bersamaan, memberikan rekomendasi produk kepada seseorang berdasarkan riwayat historis pembelian produk, menyusun rak display, dan menyusun halaman produk e-commerce. Inovasi ini akan banyak memecahkan masalah di bidang sales marketing dan inventory, karena produk yang tidak begitu laku jika dipasangkan dengan tepat akan naik nilai penjualannya. Namun mencari asosiasi membutuhkan proses yang rumit karena masalah kombinasi produk yang besar apalagi jika bisnis ritel tersebut memiliki ribuan produk. Diperlukan algoritma yang mumpuni, dan di dunia data science ini dikenali dengan tipe association rules, dan salah satu yang sangat populer adalah apriori.Algoritma apriori termasuk jenis aturan asosiasi pada data mining, algoritma apriori yang bertujuan untuk menemukan frequent item sets dijalankan pada sekumpulan data. Analisis apriori didefinisikan suatu proses untuk menemukan semua aturan apriori yang memenuhi syarat minimum untuk support B
The purpose of this research is to describe the representation of sixth grade students in solving mathematics word problems. The focus of the representation of this research is an external representation which is viewed from students with high mathematical abilities. The method used in this research is task-based interview, by giving a problem test of word problems. Students who have a high level of abilities, he makes pictures of all problems and successfully solve the problems. Students whose level of abilities is lacking, he only makes incomplete symbol / verbal representations, he has wrong when solving the problems. Various kinds of representations and increasing abilities in many problems such as multiplying exercises and solve the word pronlem. Applying various representations to students are very important to be improved by students in order to succeed in solving various mathematical word problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
