Abstract

Niat membeli dapat dipengaruhi oleh pemasaran tradisional maupun digital. Penelitian ini memiliki tujuan untuk mengetahui pengaruh pemasaran tradisional dan digital, serta efek moderasi pandemi Covid-19 terhadap niat membeli vitamin. Dalam penelitian ini, sampel yang terkumpul sebanyak 245 respondenyang diperoleh dari kuesioner yang dibagikan secara online melalui google form. Untuk analisis data, penelitian ini menggunakan Partial Least Square – Structural Equation Modeling (PLS-SEM) dengan bantuan software SmartPLS. Hasil penelitian ini menunjukkan bahwa pemasaran tradisional dan digital memiliki pengaruh terhadap niat membeli. Sementara itu, pemasaran tradisional yang dimoderasi oleh pandemi Covid-19 tidak memiliki pengaruh terhadap niat membeli, namun hasil yang berbeda untuk pemasaran digital dimana pandemi Covid-19 memoderasi hubungan antara pemasaran digital dan niat membeli. Purchase intention can be influenced by both traditional and digital marketing. This study aims to determine the effect of traditional and digital marketing, as well as the moderating effect of the Covid-19 pandemic on the intention to buy vitamins. In this study, the sample collected was 245 respondents obtained from questionnaires distributed online via google form. For data analysis, this study uses Partial Least Square – Structural Equation Modeling (PLS-SEM) withSmartPLS software. The results of this study indicate that traditional and digital marketing have an influence on purchase intention. Meanwhile, traditional marketing moderated by the Covid-19 pandemic had no effect on purchase intention, but the results were different for digital marketing where the Covid-19 pandemic moderated the relationship between digital marketing and purchase intention.

Abstract

Water is one of the important or basic needs for human life. The availability of water in Indonesia is an advantage that our nation has that has not been optimized. Generally, water pumps are driven by electrical energy, but it is possible to be driven by other energy, namely petroleum energy (with a combustion motor). Alternative energy that can be used is thermal energy. Thermal energy can come from coal, solar energy, geothermal or waste heat from industries that are no longer used. The purpose of this study was to determine the discharge, pump power and maximum efficiency. The working fluid used is diethyl ether. The heat comes from an electric stove which will heat the working fluid, namely diethyl ether. The variables measured were temperature, volume and pumping time. Variables that are varied are variations in the height of the pumping head, (1) 170cm, (2) 244cm and (3) 325cm. Variations in the volume of diethyl ether in the reservoir tube, (1) 653ml, (2) 717ml and (3) 844ml. Variations in the volume of compressed air in the compressed tube, (1) 5.49 liters, (2) 4.71 liters, and (3) 3.14 liters. Variations in the use of compressed air tubes, (1) one compressed air tube and (2) two compressed air tubes. The results showed that the maximum discharge of 0.63 liters/minute was obtained at variations in the height of the pumping head 1.7m, ether volume 653ml, compressed air volume 3.14 liters, and using one compressed air tube. The maximum pump power of 0.185 watt and the maximum pump efficiency of 0.047% were obtained at variations in pumping head height of 3.25m, volume of ether 653ml, compressed air volume of 3.14 liters, and using one compressed air tube.
