IMPLEMENTASI ALGORITMA APRIORI UNTUK MENCARI POLA TRANSAKSI PENJUALAN PADA KD CAKE
Get PDFKD Cake, sebuah usaha kue dan jajanan pasar di Kabupaten Ponorogo, menghadapi tantangan dalam menarik minat pelanggan di industri makanan yang sangat kompetitif. Selama ini, data transaksi penjualan hanya disimpan sebagai arsip, padahal data tersebut bisa diolah menjadi informasi yang bermanfaat untuk meningkatkan penjualan dan inovasi produk. Penerapan teknik data mining, khususnya Algoritma Apriori, dapat membantu mengidentifikasi pola transaksi penjualan dengan menemukan produk yang sering dibeli bersamaan dalam satu transaksi. Algoritma Apriori digunakan untuk menganalisis hubungan antar item dalam data penjualan dan menemukan aturan asosiasi berdasarkan data transaksi penjualan. Informasi ini memungkinkan penjual memberikan rekomendasi produk yang lebih tepat kepada pembeli, meningkatkan penjualan produk yang kurang laku dengan strategi seperti potongan harga, bundling produk, atau diskon pembelian. Dengan demikian, KD Cake dapat mengoptimalkan transaksi penjualan dan merencanakan strategi bisnis yang lebih efektif untuk mencapai peningkatan transaksi penjualan dan laba maksimum sesuai tujuan perusahaan. Hasil dari apriori data sebanyak 100 setelah dilakukan perhitungan menghasilkan rekomendasi produk yang sering dibeli yaitu jika pembeli membeli Lemper, Donat, maka konsumen juga akan membeli Risol dengan nilai Confidance 100% dan nilai lift 1.43 dengan keterangan kolerasi positif

PENGARUH PENAMBAHAN PANI/t-ZrO2 PADA CAT TERHADAP KEMAMPUAN MENGHAMBAT LAJU KOROSI LOGAM BAJA ST-42
Get PDFCorrosion is a major problem in industry, causing material damage and reducing the lifespan of components. To address this issue, the development of effective anti-corrosion coatings is crucial. This research aims to analyze the effect of varying PANI/t-ZrO2 composite additions to paint on the corrosion resistance of the coating layer. PANI is known for its conductive and anti-corrosive properties, while ZrO2 is a refractory ceramic with low thermal conductivity, high hardness and density, and excellent corrosion resistance. The substrate used is ST-42 steel, a metal commonly used in everyday applications. Concentrations of t-ZrO₂ at 2.5%, 5%, 7.5%, and 10% were tested to determine the optimal composition. Corrosion testing was conducted using the Tafel polarization method in a 3.5% NaCl solution over 21 days to evaluate corrosion protection. Results show that the addition of PANI/t-ZrO₂ significantly improves the corrosion resistance of ST-42 steel compared to paint without composite additives. A concentration of 5% t-ZrO₂ in the PANI/t-ZrO₂ composite provided the best protection, with the lowest corrosion rates recorded at 0.0000653 mpy on the first day and 0.00089 mpy on the 21st day. However, at higher concentrations of 7.5% and 10%, the effectiveness of the corrosion protection layer tends to decrease
