Abstract

This study aims to determine the effect of consumer trust on purchase intention on the online shopping site Shopee. This research uses a quantitative approach with descriptive methods. The population in this study were Economics Education students at the Faculty of Teacher Training and Education at the Syiah Kuala University (FKIP USK). The sample used was 47 respondents with the accidental sampling method. Meanwhile, data collection techniques used library research and field research. The data analysis technique used is simple linear regression analysis and t test. Based on the results of the regression test, Y = 4.576 + 0.435X. Then the t test at a significant level of 5%, the hypothesis is accepted, as evidenced by the value of t_count = 6.375 t_table = 2.0141. The coefficient of determination (R Square) of 0.475 or equal to 47.5% means that the consumer trust variable affects the purchase intention variable, while the remaining 52.5% is influenced by other variables. The conclusions from this study indicate that consumer trust has a positive and significant effect on purchase intention on the online shopping site Shopee among students.

Abstract

This study classifies the Seurapoh plant (Chromolaena odorata Linn) collected from various locations across Aceh Province. The analysis aims to determine the influence of geographic differences on the origin of Seurapoh plants by performing classification and authentication. Seurapoh leaf samples in this study were obtained from several locations, including Aceh Besar, Sabang, Southwest Aceh, South Aceh, Aceh Jaya, Bireun, Bener Meriah, and Central Aceh. Classification of Seurapoh leaf extracts was carried out using Principal Component Analysis (PCA), while authentication was conducted using Linear Discriminant Analysis (LDA). The PCA score plot analysis results indicate that it can explain a total data variance of 62%. Based on the PCA score plot, samples generally form three distinct groups: Group 1 consists of samples from the highland region of Gayo, specifically Central Aceh (TA) and Bener Meriah (BM); Group 2 consists of samples from the coastal areas of Aceh, namely Southwest Aceh (ABD), South Aceh (AS), Aceh Jaya (AJ), and Bireun (Br); and Group 3 comprises samples from geothermal manifestation areas of Seulawah Agam and Jaboi. The classifications derived from PCA analysis were subsequently authenticated using LDA. The LDA analysis results indicate that the LDA model, based on cross-validation, accurately predicts the origin locations of Seurapoh leaf samples with a 100% accuracy rate.
