Abstract

This research enhances data security for geolocation information derived from IP addresses using RSA encryption. In today’s digital era, protecting sensitive data is crucial, as personal information is often transferred and stored electronically. Encryption is a key security method that transforms readable data (plaintext) into unreadable code (ciphertext) without the correct decryption key, thereby safeguarding it from unauthorized access. The RSA algorithm, specifically with a 2048-bit key length, has proven effective in securing geolocation data against brute-force attacks, ensuring that only authorized users with the correct decryption key can access the information. This study confirms that RSA encryption allows encrypted geolocation data to be stored safely in databases, maintaining data confidentiality and integrity. Ultimately, this research contributes to the understanding of RSA cryptography's application in data encryption for IP-based location data, offering a reliable method to prevent data manipulation and unauthorized access.

Abstract

Dimsum Homemade's marketing strategy in the culinary field is one of them by increasing innovation in dimsum variants. However, some Homemade Dimsum business actors have shortcomings in understanding the purchasing patterns of dimsum products because there are too many variants of dimsum today. Dimsum Homemade business actors should know the most popular dimsum variants. This relates to the availability of which dim sum stock is the most so as not to experience large losses. So in this case technology is needed related to the dimsum variant purchase pattern algorithm so that sales data accumulates properly and it is easy to find out which dimsum variants are in great demand. One of the solutions needed is to apply the Association Rule Mining method using the a priori algorithm calculation. Application of Association Rule Mining (association rules), which is a data mining technique to find association rules for a combination of items. Based on the description of the problem above, the purpose and objectives of this study are to apply the Association Rule Mining method using the apriori algorithm to make it easier to analyze which dim sum variants have a high level of sales together. Thus the results obtained can be used to help make decisions in increasing accurate stock inventory and better product promotion. Association rules with apriori algorithm calculations can result in Homdemade dimsum purchase patterns, namely there are several association rule patterns that have a fairly high support and confidence value. For example, it is stated that the “Shrimp” dimsum menu has a tendency to buy the “Chicken” dimsum menu and vice versa. Then the “Chicken” dimsum menu becomes a menu associated with other dimsum menus, although the support and confidence values vary.

Abstract

The rapid growth of information and communication technology in Indonesia has heightened the need for fast, reliable data access, especially for organizations managing large, distributed workforces. This study proposes an Android-based attendance application using Location-Based Service (LBS) to address the limitations of the current web-based HR system at PT Infomedia Solusi Humanika (ISH), a Human Capital Services provider under the Telkom Group. ISH oversees over 28,000 employees across 420 cities, yet the existing system struggles to support attendance tracking for employees at client offices, affecting records such as leave, performance, and payroll. To solve this, an Android application utilizing the Haversine Formula for accurate location mapping within a 100-meter radius allows employees to log attendance remotely. Developed using the Rapid Application Development (RAD) method, the app enables employees to handle attendance, leave requests, and overtime tracking directly through their mobile device, removing the need to access a browser. This solution enhances usability, increases HR efficiency, and ensures accurate performance records, supporting ISH's reputation as a modern HR management provider.
