Abstract

The GOBIS application, developed by the Surabaya City Transportation Department, is a digital service designed to provide public transportation information and reduce traffic congestion. Despite having exceeded 100,000 downloads, the application has received numerous complaints from users, as reflected in the multilingual reviews on its platform. To ensure analytical consistency, this research focuses solely on reviews in Indonesian and English. Using Aspect-Based Sentiment Analysis (ABSA), this study employs Latent Dirichlet Allocation (LDA) for aspect identification and Support Vector Machine (SVM) for sentiment classification. The aim of this research is to determine the dominant aspects in user feedback and evaluate the effectiveness of the Support Vector Machine (SVM) model in classifying multilingual reviews. The research results show six main aspects that frequently appear in reviews, namely Application Features and Development, User Suggestions and Service Innovation, Error and Location Accuracy, Delay and Application Usability, Comfort and Service Quality, as well as Route Tracking and Vehicle Information. The Support Vector Machine (SVM) model, tested with 10-fold cross-validation, demonstrates consistent performance, achieving balanced metrics accuracy (74.16%), precision (73.76%), recall (73.54%), and F1-score (73.63%). This highlights its capability in handling multilingual sentiment analysis for application improvement.

Abstract

The objective of this study is to provide an innovative solution to enhance communication between students and university administration by designing a student complaint management system. In this context, the system is designed to facilitate efficient and effective handling of student complaints. Through a web-based application, students can easily submit complaints anytime and anywhere using an internet-connected device. The key features of the developed system include online complaint submission, real-time notifications, complaint status tracking, and a complaint management system that enables university administrators to respond to and resolve issues more promptly. The success indicators of this system include a fast response time—where complaints can be processed quickly—and a high level of user satisfaction regarding the efficiency and ease of use of the system. In this study, we adopted the Waterfall development methodology due to its structured and systematic approach, which facilitates planning and testing at each stage of development. This method allows developers to focus on one phase at a time, reducing the risk of errors during implementation. Furthermore, the Laravel framework was chosen for its ease of management, Model-View-Controller (MVC) architecture—which separates application logic from the user interface—and robust security features to protect user data and system integrity. The results of this study demonstrate that a student complaint system can be successfully designed and implemented, offering an effective solution for complaint management in educational settings. With this system, communication between students and university staff is expected to improve, and issues can be resolved more efficiently.

Abstract

Dalam sebuah acara seminar nasional, evaluasi kepuasan peserta menjadi aspek penting untuk menilai keberhasilan acara dan mengusulkan perbaikan di masa mendatang. Salah satu metode evaluasi yang umum digunakan adalah survei online, yang sering kali mencakup pertanyaan terbuka (open-ended) agar peserta dapat menyampaikan opini dan pengalaman mereka secara bebas. Namun, respons survei open-ended bersifat tidak terstruktur, sehingga analisis manual menjadi kurang efektif karena memerlukan banyak waktu dan rentan terhadap subjektivitas. Analisis mendalam terhadap respons survei open-ended diperlukan untuk memahami opini peserta mengenai kualitas acara. Penelitian ini bertujuan untuk mengklasifikasikan sentimen dan mengidentifikasi aspek utama dalam respons survei open-ended dari peserta seminar. Penelitian ini menggunakan Metode Latent Dirichlet Allocation (LDA) untuk topic modeling, dan Support Vector Machine (SVM) untuk klasifikasi sentimen. Hasil penelitian menunjukkan bahwa kombinasi SVM dan teknik resampling Synthetic Minority Over-sampling Technique (SMOTE) menghasilkan performa terbaik dengan akurasi 85%, Precision 0.78, Recall 0.88, dan F1-Score 0.81. Analisis LDA berhasil mengidentifikasi 9 topik utama yang mencerminkan aspek penting dalam respons peserta, dengan mayoritas sentimen yang ditemukan bersifat positif, terutama dalam topik Manfaat atau Materi.

Abstract

Penurunan penjualan di Kopi Mesra Abadi, yang turun dari surplus 131,6% pada Oktober 2023 menjadi 37,96% pada Maret 2024, menunjukkan perlunya strategi promosi yang lebih relevan untuk mencapai target penjualan per bulan. Penelitian ini bertujuan untuk merancang strategi promosi yang lebih relevan dengan menggunakan analisis pola pembelian pelanggan dan menu yang sering dibeli bersamaan. Metodologi yang digunakan mencakup dua algoritma: FP-Growth dan K-Means Clustering. FP-Growth digunakan untuk menemukan Frequent Itemsets dan Association Rules guna mengidentifikasi kombinasi menu yang sering dibeli bersama. K-Means Clustering digunakan untuk mengelompokkan pelanggan ke dalam tiga klaster berdasarkan waktu pembelian di tiga sesi: Sesi 1 (09.00-13.59), Sesi 2 (14.00-16.59), dan Sesi 3 (17.00-23.59). Hasil penelitian menunjukkan bahwa pembagian pelanggan ke dalam klaster per sesi membantu merancang paket menu yang sesuai dengan preferensi mereka. Sebagai contoh, Sesi 1 Klaster 0 lebih memilih "Nasi Ayam Pedas" dan "Teh O" untuk makan siang, Sesi 2 Klaster 2 memilih "Nasi Ayam Telor Asin" dan "Nasi Goreng Mawut" untuk pulang kerja, dan Sesi 3 Klaster 2 memilih paket Executive Meeting dengan "Kopi Butter," "Kopi Karamel," dan "Kopi Baileys." Penerapan FP-Growth dan K-Means membantu merancang paket menu yang menarik dan mencapai target penjualan.

Abstract

In higher education, overseeing the execution of litabmas activities is a challenging and error-prone task, particularly when done manually through the physical submission of documents. Information is not always readily available, archives are frequently lost or even damaged, and tracing Litabmas external responsibility (articles, journals, patents/IPRs, etc.) from earlier periods can be challenging. This article describes how the Waterfall approach was used to construct the Litabmas management application. The Hierarchical Model-View-Controller (HMVC) technique is used to build the code architecture during the coding process. By reducing intermodular dependencies, this method makes it easier for a team to design an application. This application was developed to facilitate the management of the full cycle of Litabmas activity implementation for users, from generating Litabmas master data to initiating the Litabmas period, submitting proposals, conducting evaluations, and reporting Litabmas outputs and outcomes. The application has been tested using the black box method, and as a result, 23 use cases from six levels of users —administrator, head of institutional research, researcher, reviewer, auditor, and general visitor access rights —have been generated. All of these usecase have 100% of the expected output produced by the application.

Abstract

Technological developments and globalization encourage people to develop in the transaction process. Now, conventional technology is starting to be abandoned and switched to a digitalization system, thus strengthening the balance of trade on an international scale. As one of the global e-wallets, PayPal offers convenience in cross-border transactions, but there are not many studies that specifically evaluate the level of satisfaction of Indonesian users in the application of this service. This research focuses on analyzing the level of satisfaction of using PayPal in Indonesia in cross-border transactions and examining technology acceptance factors with the Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2) method. Data were collected through distributing questionnaires to active PayPal users in Indonesia and analyzed quantitatively using structural regression methods (SEM/PLS). The results showed that perceived ease of use, usefulness, and trust have a significant influence on user satisfaction. In addition, UTAUT 2 variables such as performance expectations, effort expectations, social influence, and hedonic value also contribute to forming positive perceptions of using PayPal. The findings are expected to contribute to the development of an international digital payment system that is more responsive to the needs of users in Indonesia.
