Abstract

Penelitian ini bertujuan merancang dan mengembangkan Sistem Informasi Penjualan berbasis web untuk Gerai Oleh-Oleh Bali yang selama ini masih menggunakan pencatatan manual dengan buku besar dan perhitungan menggunakan kalkulator. Sistem manual tersebut menyebabkan risiko kesalahan pencatatan, lambatnya proses pencarian data, serta kesulitan dalam pengarsipan data penjualan, pembelian, pemesanan, dan pengelolaan stok barang. Penelitian menggunakan metode pengembangan perangkat lunak Waterfall dengan pendekatan pemodelan Unified Modeling Language (UML). Tahapan yang dilakukan meliputi analisis kebutuhan melalui wawancara dengan pemilik gerai, perancangan sistem (Use Case Diagram dan Class Diagram), implementasi, pengujian unit, pengujian sistem menggunakan metode black-box testing, serta tahap pemeliharaan (maintenance). Sistem yang dibangun mencakup fitur login, dashboard, pengelolaan data master (supplier dan barang), transaksi penjualan dengan dukungan scan barcode, transaksi pembelian, laporan penjualan dan pembelian, serta pengelolaan user. Hasil pengujian black-box menunjukkan seluruh test case berstatus Valid dan sistem berfungsi sesuai harapan. Pada tahap maintenance dilakukan contoh corrective maintenance dengan perbaikan bug pada query laporan penjualan harian.Sistem informasi penjualan berbasis web yang dihasilkan mampu mempercepat proses transaksi, mengurangi kesalahan manusia, meningkatkan akurasi data, serta memudahkan pengelolaan stok dan pembuatan laporan secara real-time. Implementasi sistem ini memberikan solusi efektif bagi Gerai Oleh-Oleh Bali dalam meningkatkan efisiensi operasional dan interaksi dengan pelanggan.

Abstract

Online marketplaces in Indonesia generate massive unstructured consumer reviews laden with slang and informal language, posing challenges for standard sentiment analysis systems. This Systematic Literature Review (SLR), following PRISMA 2020 guidelines, synthesizes 32 primary studies from Google Scholar, Scopus, and IEEE Xplore (2014–2025) to address four analytical research questions on slang normalization effectiveness, LSTM performance relative to dataset characteristics, trade-offs of imbalanced data handling methods, and contexts where F1-Score outperforms accuracy. Results show dictionary-based normalization achieves 87.3% accuracy versus 59% for automated methods. LSTM consistently outperforms traditional models on large, long-text datasets but remains sensitive to preprocessing quality. SMOTE is the most adopted technique yet underperforms at imbalance ratios exceeding 10:1. F1-Score is confirmed as the most representative metric for skewed datasets. This study proposes an integrated conceptual framework and identifies future research gaps including sarcasm detection, code-mixing, and Transformer-based approaches.

Abstract

The development of information technology has brought significant changes in various aspects of life, including in the field of religious services. The church as a religious institution has a responsibility to convey information, coordinate activities, and establish effective communication with the congregation. The GKPB Philadelphia Legian Congregation Church has so far relied on conventional communication media such as bulletin boards and direct information delivery during services. This method has limitations in terms of reach and speed of information dissemination. Therefore, a digital media is needed that can facilitate the delivery of information, increase congregation participation, and support church service activities on an ongoing basis. Utilizing the church's official website as an information and communication center is one way to solve these problems. This community service activity is carried out through several stages including Needs Analysis, Website Design and Development, as well as Socialization and Training for church administrators on how to manage and update website content. Community service activities through the use of the website at the GKPB Philadelphia Legian Congregation Church can improve the effectiveness of church communication and services. This website is a strategic tool in supporting information dissemination and increasing congregation involvement.

Abstract

Pembelajaran Bahasa Inggris menjadi salah satu bahasa yang wajib diperkenalkan kepadaanak-anak. Model pembelajaran konvensional mengenalkan Bahasa Inggris seringkali tidakberhasil karena kurang menariknya proses pengenalan dan pembelajaran Bahasa Inggristersebut. Untuk itu, diperlukan metode pembelajaran yang memanfaatkan teknologi dalampembelajaran, salah satunya dengan gamifikasi. Penelitian ini bertujuan untuk membuatperancangan aplikasi berbasis Android untuk mengimplementasikan gamifikasi pada prosespembelajaran Bahasa Inggris menggunakan aplikasi yang dinamakan Gamebira.

Abstract

The use of Augmented Reality (AR) in learning is becoming increasingly widespread, especially for introducing cultural and historical material in a more interesting way. However, many AR applications are still built without a structured design, making them difficult to develop when content is added. This study uses a Model-Driven Design (MDD) approach to organize the design of the ARrupiah application to make it more modular and easier to expand. After the prototype was completed, testing was conducted through surveys and interviews. The Kano survey involved 50 students to evaluate the main features of the application, while semi-structured interviews were analyzed using NVivo software to explore response patterns and user experiences, with a code saturation level of 80%. The survey results showed that around 70% of the features fell into the Attractive category, with a System Usability Scale (SUS) score of 82/100, indicating ease of use. Qualitative analysis reinforced the quantitative results through a triangulation process, in which features categorized as Attractive also emerged as a dominant theme of visual engagement in the NVivo results. This combined approach strengthens the validity of the findings and provides a more comprehensive understanding of user perceptions and satisfaction. Overall, the application of MDD not only helps refine the technical design but also improves the quality of the learning experience through ARrupiah-based interactive media.

Abstract

The application of Augmented Reality (AR) technology in library services has the potential to enhance the user experience through more interactive and engaging information presentations. This study aims to create an augmented reality (AR) book search system that uses marker-based tracking to help students find references at the Dhyana Pura University Library, while also measuring how satisfied users are using the Kano Model. The system was created using the waterfall approach for developing software and used Unified Modeling Language (UML) to outline how activities flow and how different parts of the system connect. The satisfaction test involved 54 respondents, with attribute analysis using the Kano Model and Customer Satisfaction Coefficient (CSC). The results of the study show that most of the application features fall into the Attractive category, which indicates that these features provide added value and a positive experience for users. The combination of UML-based system design and evaluation with the Kano Model was successful in creating a library application that is functional, easy to use, and focused on user satisfaction.
