Abstract

The aim of the study was to determine the pattern of relationship between the sales turnover variables of cake vendors, the use of wheat flour, and gender. Knowing the best equation model that shows the relationship pattern of cake vendor sales turnover variables, the use of wheat flour, and gender. Determine the cells that cause the relationship between variables to be dependent. The data analysis method used in this research is the Linear Log Model with the best model using the Backward method. The data in this research is secondary data from a survey at PT. BOGASARI in November 2022. The conclusions obtained in this study are that there is a relationship between the variable sales turnover of traders every day and the use of wheat flour for golden carriages. The best model showing the pattern of relationship between the sales turnover variables of cake vendors, the use of carriage golden flour, and gender is log . Male traders whose daily turnover is < Rp. 500,000.00 tend to use Kereta Kencana flour, while female traders whose turnover is < Rp. 500,000.00 per day tend not to use Kereta Kencana flour.

Abstract

The rapid development of technology causes the use of mobile phones and the need for pulses to increase. East Lombok is the area with the largest population in NTB and high users of information technology. East Lombok also has an internet network or smooth communication signal, which shows that there are many providers in the area. To see the types of providers that are widely used in Masbagik District, East Lombok, taking into account the largest population, a classification is made of whether these providers are in demand or not using the Naïve Bayes method. This study aims to determine the classification results and the accuracy of the sales classification of credit providers. The data is split into two categories: training data (90%) and testing data (10%). According to the findings of the study, 225 of the 309 testing data were correctly classified. The resulting APER value is 27.2%, which indicates that the accuracy of the classification results using the Naïve Bayes method is 72.8%. An AUC value of 0.804 was also obtained, which means that the accuracy of the classification of selling pulse providers that are in demand, moderately in demand, and not in demand was sufficient.
