Abstract

Gereja Katolik Paroki St. Agustinus Karawaci sudah memiliki website yang dibuat dan dikelola mandiri. Namun sayangnya informasi yang tersedia pada website tersebut tidak pernah diperbarui. Bagi umat yang mengakses website tersebut cenderung tidak percaya karena konten yang ada dalam website tersebut statis, dan tidak up-to-date. Oleh karena itu kami berkeinginan untuk membuatkan aplikasi berbasis Android yang dapat dipercaya oleh para umat dalam mencari informasi yang berkaitan dengan Gereja Katolik Paroki St. Agustinus Karawaci. Kegiatan dilakukan dimulai dari melakukan survey awal bersama dengan pihak Gereja Katolik Paroki St. Agustinus Karawaci. Setelah melakukan survey awal, selanjutnya melakukan identifikasi permasalahan yang ingin diselesaikan dalam kegiatan pengabdian kepada masyarakat ini. Adapun hasil dari survey awal adalah Gereja Katolik Paroki St. Agustinus Karawaci membutuhkan suatu aplikasi berbasis Android yang dapat membantu umat Gereja mendapatkan informasi. Kegiatan yang telah dilakukan adalah memberikan pelatihan pembuatan konten video yang berkualitas. Kegiatan lanjutan adalah menyediakan aplikasi berbasis Android bagi Gereja Katolik Paroki St. Agustinus Karawaci agar dapat memudahkan dalam penyebaran informasi terkait acara Gereja.

Abstract

The use of System Application and Processing (SAP) software is becoming increasingly popular among businesses, and ensuring employees receive adequate training is essential for effective use. However, there are common problems associated with SAP training, such as the lack of adequate training materials, training module quality, insufficient training facilities, and inadequate coach quality. These problems can result in employees not receiving the training they need to operate the software effectively, leading to a lack of productivity and efficiency in the workplace. To address these issues, the development of a training recommendation application using XAMPP, HTML, PHP, and CSS has been successful. The application offers an integrated, secure, and accurate solution to select the most appropriate SAP Training Module for each employee based on their performance across different attributes. The User Acceptance Testing (UAT) carried out with the Human Resource staff showed that the application built using the Simple Additive Weighting (SAW) method was 100% effective in selecting the best module for each employee. The SAW method considers the weighted sum of performance rankings for each module, providing a reliable and accurate recommendation for the most suitable module for each employee.

Abstract

Our study aims to develop an effective bundled product promotion strategy for the office supply store to boost sales. The primary challenge is comprehending which product combinations align with customer preferences and cater to their needs. We leverage the Apriori and ECLAT algorithms for consistent rule generation, revealing robust associations between product purchases. Notably, a strong positive correlation rule emerges at a confidence level of 0.8, while at 0.9, no results are found. The identical rules derived from both algorithms signify their reliability. The shop owner employs two rules for bundled products based on a minimum Lift Ratio of 1.96. The first bundle focuses on 70gsm natural paper in Folio and Quarto sizes, capitalizing on their popularity, even though customers may prefer one size. The second bundle emphasizes notebooks, often bought together but in smaller quantities than paper products, reflecting diverse customer needs and behaviors.

Abstract

Currently, there are a lot of Solid-State Drives or SSDs that are running in the market. Each SSD can come with different features and prices from one another. Hence, this can confuse buyers planning to purchase one for their PC or laptop. It also applies to university students who depend on laptops to do college work and run on a limited budget. Any mistake in deciding which SSD to use can be costly. Henceforth, this paper aims to help decide what SSD would be best for an average university student. Two algorithms will determine which SSDs are best for university students to buy. The algorithms used are Simple Additive Weighting and Technique for Order of Preference by Similarity to Ideal Solution. The results of these algorithms are used to show the top three best SSDs for university students. Therefore, university students can make an informed choice based on the results from both algorithms.
