Abstract

The study aims to determine the impact of the Logistic Regression method on the classification of customer bank deposits, using a public UCI Bank Marketing dataset, which contains customer-specific information of bank deposit telemarketing activities. Data has a binomial label consisting of 'yes' for subscribers and 'no' for non-subscribers. The data preprocessing phase is done with downsampling to make the amount of data more symmetrical, then data selection and data transformation to ensure that the data used values are consistent, attribute selection to select the attributes most accurately used and give significant influence. Classification is done using the Logistic Regression algorithm. Data is shared using a split method with 90% training data and 10% testing data, with the aim of optimizing the training process. The performance result consists of an accuracy of 88.53%, a classification error value of 11.4%, can be categorized as low, showing only a few errors produced by the algorithm model, a kappa value of 0.68 close to 1, so it is categorized well, a low RMSE rating of 0.3 indicates a model accurate, and a high AUC percentage of 93.4% indicates the correct algority used in this dataset, because it produces a good performance value.

Abstract

Star Silver Jewelry Shop is a business entity that operates in the field of selling silver jewelry. It was discovered that this shop still uses handwritten manual transaction proof. When a business is run manually, of course many problems arise, one of which is difficulty in managing transaction data such as proof of sales, item data, item codes and large amounts of sales results. So this research is here to provide a solution. The type of research used is research and development (R&D). This web-based application was created using the CodeIgniter 3 framework, Tailwind CSS and MYSQL database, with the PHP programming language and a little JavaScript. This website contains a login page as an initial display, where users are required to log in to validate whether the operator behind it is an officer or not, then they will be forwarded to a dashboard page with several customized menus.

Abstract

The map archiving system in the Jambi Province DPAD is currently facing quite serious challenges because it still relies on manual recording methods. This reliance on manual recording has caused the process of searching for map archive data to be slow and inefficient. Employees have to spend quite a long time searching for and managing the necessary information, resulting in disruptions in productivity and a high potential for data errors. To address this issue, we designed a solution that we believe can provide significant improvements in the management of map archive data. This project is in the form of designing a Website-Based Map Archive Data Information System which will replace the existing manual method. By using web-based technology, this system is specifically designed to increase efficiency and accuracy in managing map archives. It is hoped that with the implementation of this system, the data search and management process will become faster, easier and more structured, thereby helping to increase productivity and reduce the risk of errors in information management.

Abstract

Optimal placement of culinary tourism centers is very important to increase the attractiveness of tourist destinations and support local economic growth. This study aims to implement the Multidimensional Scaling (MDS) method in determining the most appropriate location for culinary tourism centers in a city. The Multidimensional Scaling approach is used to map visitor and stakeholder perceptions of various location determinants, such as accessibility, supporting facilities, market potential, and environmental characteristics. Data collected from surveys and field observations are processed to identify dominant perception and preference patterns, and determine the ideal coordinates for the location of culinary centers. The results of mapping using multidimensional scaling are Group 1 consisting of SWK Babat Jerawat, SWK Balas Klumprik, SWK Bratang Binangun, SWK Dharmahusada, SWK Embong Sawo, SWK Indrapura, SWK Kapas Krampung, SWK Penjaringan Sari, SWK Rmi, SWK Tanah Merah and SWK Tandes.
