Abstract

Transportasi online memberikan dampak positif bagi sebagian besar masyarakat, namun penggunaan aplikasi oleh penyandang disabilitas masih menghadapi sejumlah tantangan. Belum adanya fasilitas yang memadai dan pengalaman pengguna yang baik menjadi kendala utama. Realitas ini menunjukkan bahwa perlunya perhatian khusus terhadap prinsip aksesibilitas untuk meningkatkan pengalaman pengguna dan kenyamanan bagi penyandang disabilitas. Melalui ulasan pengguna dapat diidentifikasi aspek-aspek aksesibilitas untuk mendukung peningkatan pengalaman pengguna. Penelitian ini bertujuan mengekstraksi informasi dari ulasan pengguna terkait aksesibilitas menggunakan metode NER dengan pendekatan CNN dan LSTM. Data yang dikumpulkan melalui web scraping terdiri dari 6.255 ulasan aplikasi Gojek, Grab, Maxim, dan Indriver. Hasil evaluasi menunjukkan bahwa kedua model memiliki akurasi tinggi yaitu CNN 99,84%, dan LSTM 99,48%. Namun memerlukan perbaikan dalam mendeteksi entitas yang jarang muncul atau berkonteks kompleks. Hasil analisis menunjukkan bahwa ulasan lebih banyak membahas fitur aplikasi dan keluhan yang berkaitan dengan aksesibilitas. CNN lebih efektif dalam menangkap pola spesifik, sedangkan LSTM lebih kuat dalam menangkap variasi kata.

Abstract

Mobile banking atau M-banking menjadi semakin populer seiring dengan meluasnya penggunaan ponsel pintar. Pertumbuhan ini didorong oleh beberapa faktor, seperti kebijakan pemerintah melalui Gerakan Nasional Non-Tunai (GNTT) dan inovasi dari bank. Latar belakang penelitian ini berangkat dari pentingnya merespons keluhan pengguna terhadap aplikasi M-banking. Ulasan negatif mencerminkan masalah yang dialami pengguna dan bisa memengaruhi kepercayaan terhadap layanan. Sayangnya, platform seperti Google Play Store tidak menyediakan fitur untuk mengidentifikasi tren dari ulasan negatif. Oleh karena itu, penelitian ini menggunakan metode Latent Dirichlet Allocation (LDA) untuk memodelkan tren topik dalam ulasan negatif guna memberikan wawasan bagi penyedia layanan untuk meningkatkan kualitas aplikasi mereka. Penelitian ini dilakukan melalui beberapa tahap, dimulai dengan pengumpulan data ulasan negatif dari tiga aplikasi M-banking populer. Selanjutnya data akan melalui tahap preprocessing, meliputi: tokenizing, stopwords removal, dan stemming. Sentimen dari ulasan dianalisis menggunakan algoritma Support Vector Machine (SVM) dengan akurasi mencapai 93%, untuk memisahkan ulasan positif dan negatif. Selanjutnya, LDA digunakan untuk memodelkan topik pada ulasan negatif, dengan mengidentifikasi sejumlah topik optimal melalui Coherence Score, yang menunjukkan struktur topik yang logis dan terorganisir. Hasil penelitian menunjukkan bahwa pada BRImo, topik yang dominan adalah biaya dan kecepatan layanan aplikasi. Pada BCA mobile, pengguna lebih banyak membahas fitur dan kemudahan penggunaan aplikasi, sedangkan pada Livin’ by Mandiri, topik utama yang dibahas berkaitan dengan fitur transfer dan jam transaksi. Kesimpulan dari penelitian ini adalah bahwa metode LDA berhasil digunakan untuk menemukan tren utama dari ulasan negatif pengguna, yang diharapkan dapat membantu bank dalam meningkatkan kualitas layanan dan keamanan aplikasi mobile banking.

Abstract

COVID-19 has spread to various countries and affected many sectors, including education. New challenges arise in universities with study programs related to computer programming, which require a lot of practice. Difficulties encountered when students should setting up the environment needed to carry out programming practices. Furthermore, they should install a text editor called Integrated Development Environment (IDE) to support it. There is various online IDE that supports computer programming. However, students must have an internet connection to use it. After all, many students cannot afford to buy internet quotas to access online learning material during the COVID-19 pandemic. According to these problems, this study compares several online IDEs based on internet data usage and the necessary supporting libraries' availability. In this study, we only compared eleven online IDEs that support the Python programming language, free to access, and do not require logging in. Based on the comparative analysis, three online IDEs have most libraries supported. They are REPL.IT, CODECHEF, and IDEONE. Based on internet data usage, REPL.IT is an online IDE that requires the least transferred data. Moreover, this online IDE also has a user-friendly interface to place the left and right sides' code and output positions. It prevents the user from scrolling to see the results of the code that has been executed. The absence of advertisements also makes this online IDE a more focused appearance. Therefore, REPL.IT is highly recommended for users who have a limited internet quota, primarily to support the learning phase of computer programming during the COVID-19 pandemic.

Abstract

Purpose: Twitter related to mental health has great potential as a medium to provide important information to the public and health organizations on a large scale, but an evaluation of tweet data related to mental health disorders has not been carried out. This study aims to classify tweet data to determine the most common mental health disorders in Indonesia based on the symptoms experienced.Methodology: The classification process is carried out using cosine similarity calculations between tweets data and keywords which are compiled based on theoretical studies and optimization of the LDA topic modeling results.Findings/result:The classification results show that the most discussed issues on Twitter are depression, bipolar, schizophrenia, dementia, and PTSD. Based on these results it can be interpreted that the level of prevalence and public attention to depressive diorders is quite high compared to other disorders. From the results of the classification, it is also possible to identify the most discussed symptoms throughthe emergence of keywords from each category.Originality: Classification is calculated based on the cosine similarity between tweets and keywords compiled from human judgement and enriched using the results of LDA topic modeling to improve classification performance

Abstract

Mental health education in Z Generation still receives less attention, even though mental health disorders in adolescents can develop into serious problems if not treated early. Many students do not understand or recognize the early symptoms of mental health disorders, and there is a lack of school involvement in providing related education. Technology can be a solution to help with early detection, one of which is through the Beck Depression Inventory (BDI)-based platform from Pijar Psikologi. This activity is expected to provide an understanding of the importance of mental health and how to recognize the early symptoms of mental health disorders. Pengabdian kepada Masyarakat (PkM) activity aims to introduce early detection tools for mental health disorders for students of SMK N 02 Yogyakarta. The methods used include pre-test, socialization and dissemination of research results, the practice of using early detection platforms, and post-test. Based on the results of the comparative analysis of pre-test and post-test scores, there was an increase in participants' knowledge regarding mental health by 90%. This shows that the delivery of the material provided is effective in increasing participants' knowledge. This increase in knowledge can be the basis for students to become cadres who are directly involved in disseminating digital literacy related to the use of information technology in mental health.

Abstract

Mobile banking has become one of the most popular choices compared to other online banking services. Google Play Store is an online application store platform provides a review section for users to give ratings and comments on the applications they use. Positive reviews typically contain good experiences that reflect user satisfaction, while negative reviews usually contain poor experiences that indicate complaints and user dissatisfaction. However, Google Play Store does not yet have a feature to automatically map the main topics in both positive and negative reviews. Specifically for negative reviews, this can make it difficult for developers to understand the root problems and take appropriate corrective actions. In some situations, negative reviews need to be handled more quickly. Slow handling of negative reviews can impact the decline in reputation and customer loyalty. This research aims to identify user dissatisfaction topics based on negative reviews of several popular mobile banking applications in Indonesia, namely BCA Mobile and BRImo.
