E-wallets such as ShopeePay and DANA have become popular in Indonesia due to the ease, speed, security, and flexibility of transactions they offer. This study aims to evaluate and compare the performance of the two e-wallets using the Simple Additive Weighting (SAW) method. The SAW method is used to analyze and compare alternatives based on a number of predetermined criteria, such as ease of use, security, transaction speed, costs, and user satisfaction levels. Research data was obtained from various sources related to the performance of the two applications, including usage statistics and user reviews. The results of the analysis show that both apps have advantages in certain criteria; for example, ShopeePay is superior in transaction fees, while DANA stands out in speed and security. However, an overall assessment based on the weighting of the criteria reveals a final score that provides important insights for both users and developers. However, analysis using the SAW method provides deeper insight into the advantages of each application based on the weight of the relevant criteria. This study is expected to help users choose an e-wallet that suits their needs and provide guidance for application developers to improve service quality.</em></p> Mhd.

However, budget limitations are often an obstacle in choosing a laptop that suits the needs and financial capabilities. This research aims to implement the Simple Additive Weighting (SAW) method in an economical laptop recommendation system for students. The way this method works is by calculating alternative choices based on predetermined weights and criteria then sorting to find the best alternative from all existing criteria. So that the results will get a laptop recommendation that is closest to the suitability of the needs of prospective laptop users. The criteria used in the study include price, processor, RAM, storage capacity, and battery life. Sample data is taken from 8 laptop models with a price range of 3-7 million available on the market. The results showed that the application of the SAW method successfully provided laptop recommendations that were in accordance with the needs and budget limitations of students. With this recommendation system, students can more easily choose a laptop that suits their academic needs and budget limitations. This research is expected to be a reference for the development of decision support systems in the selection of efficient and appropriate technology devices.</em></p> Yolanda Victoria Damanik Endang Kartika Sabrina Fadillah Muhammad Robbi Akbar Pohan Victor Asido Elyakim P Copyright (c) 2024 Yolanda Victoria Damanik, Endang Kartika, Sabrina Fadillah, Muhammad Robbi Akbar Pohan, Victor Asido Elyakim P https://creativecommons.org/licenses/by/4.0 2024-11-25 2024-11-25 3 2 96 108 10.55123/jumintal.v3i2.4836 Sistem Informasi Geografis Pemetaan Kepemilikan Tanah (Studi Kasus di RT 05 RW 03 Desa Klaling) https://journal.literasisains.id/index.php/jumintal/article/view/4842 <p><em>This research entitled "</em> <em>Geographic Information System for Mapping Land Ownership (Case Study in RT 05 RW 03 Klaling Village)" aims to develop a web-based application that facilitates public access to land information. In the era of information technology advancement, limited access to land information in Klaling Village is a SIGnificant problem, where people still have to visit the village office or land office manually, which is often inefficient. The research method used is the Waterfall method, which allows system development to be carried out in a structured and planned manner. The Geographic Information System (GIS) application developed in this study has succeeded in providing land ownership information online, allowing residents to search for and measure land easily. In addition, this system is expected to reduce the possibility of fraud in the shifting of land ownership rights. The results of the study show that the implementation of web-based GIS in Klaling Village increases the efficiency of access to land information. Residents can quickly and easily see the status of land ownership in their area, which reduces dependence on slow and inefficient traditional methods. The process of searching and verifying land data that previously took time can now be done online, increasing operational efficiency for all parties involved. The conclusion of this study confirms that the information system developed not only increases the accessibility of land information, but also supports better land management. Thus, this application has the potential to provide a positive impact on the community and government in making decisions related to land.</em></p> Wahyu Cahyoaji Muhammad Imam Ghozali Wibowo Harry Sugiharto Copyright (c) 2024 Wahyu Cahyoaji, Muhammad Imam Ghozali, Wibowo Harry Sugiharto https://creativecommons.org/licenses/by/4.0 2024-11-25 2024-11-25 3 2 109 117 10.55123/jumintal.v3i2.4842 Optimasi Pemilihan Smartphone Gaming Terbaik di Kelas Menengah Menggunakan Metode Simple Additive Weighting (SAW) Berbasis Preferensi Konsumen https://journal.literasisains.id/index.php/jumintal/article/view/4831 <p><em>The selection of middle-class gaming smartphones is a challenge for consumers because there are many choices with varying specifications.
