Abstract

PT Dharmaputra Jaya Bersama is a company engaged in the sale of building materials such as nails, cement, sand, and ceramics, located in Palembang, South Sumatra. To improve the efficiency of sales strategies an inventory management, the company requires an analytical system capable of identifying customer purchasing patterns based on transaction data. This analysis applies data mining techniques using the FP-Growth algorithm to discover associations between products thatare frequently purchased together. The results can support decision-making in inventory control and sales strategies. By utilizing this approach, the company is expected to enhance operational efficiency, minimize overstocking or stockouts, and design more accurate promotional efforts based on customer purchasing behavior.

Abstract

This paper reports ZnPt bimetallic nanoparticles (ZnPtBNs) synthesis through the liquid phase deposition (LPD) of of Zn(NO3)2.6H2O onto the indium-titanium oxide (ITO) substrates at various concentrations. The Effects of growth solution, the morphology, structural, and sheet resistance were studied. After preparation, the materials were characterized by using field emission electron microscopy (FESEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD) and Four Point Probe (FPP) measurement by using Keithley 2401 source-meter. By inserting a growth solution into the ITO substrate the ZnPtBNs was successfully in-situ prepared. The synthesized ZnPtBNs exhibited homogeneous, fibrous at the (111) orientation with an average diameter of 100-700 nm. The atomic ratio of Zn:Pt and sheet resistance of ZnPtBNs decreased with the increase of Zn(NO3)2.6H2O concentration. The optimal elemental composition of the sample was at a ratio of Zn:Pt (1:25) obtained at 0.467 mM of Zn(NO3)2.6H2O. It showed the smallest sheet resistance (13.41 ?) which was 38% lower than the ITO sheet resistance (18.44 ?).
