Abstract

The increased use of gaming apps on platforms like the Google Play Store has signaled the importance of user reviews as a source of app quality evaluation. However, sentiment analysis of Indonesian-language reviews faces challenges due to the peculiarities of language structure, emotional expressions, and the use of slang and specialized terms in game reviews. This study aims to classify reviews into three sentiment classes: positive, negative, and neutral, using the IndoBERT-base-uncased model. The type of research used is experimental by comparing the performance of the model using original and synthetic datasets. The total original dataset collected was 998 reviews. The k_neighbors SMOTE parameter used is 5. The IndoBERT-base-uncased epoch parameter is 10, with a batch value per device and a batch for evaluation of 16. Configuration variable warmup_steps is 500 with L2 weight_decay regularization at 0.01. Evaluation results after SMOTE implementation: the precision score increased from 0.44 to 0.45, and the F1-score from 0.46 to 0.47. However, the recall score did not increase. The evaluation results show that the model has variable performance between classes with an initial accuracy of 69.,5%. Data imbalance is a major challenge, especially in minority classes such as class 1 (neutral), which cannot be predicted by the model. The SMOTE technique successfully improved data balance and increased accuracy to 72.5%, as well as improving metrics such as precision, recall, and F1-score overall.

Abstract

Abstrak : Sebagian besar pelayanan publik di era ini masih menggunakan sistem konvensional. Yang mana, klien layanan mendapatkan tiket antrean, menunggu, dan dilayani di tempat yang sama. Penelitian ini bertujuan untuk memudahkan dan memungkinkan orang untuk mengantre dari jarak jauh. Dengan demikian waktu yang awalnya digunakan untuk dihabiskan menunggu, bisa digunakan untuk dihabiskan melakukan sesuatu yang lain lebih berguna.Berdasarkan kondisi yang dikatakan di atas, aplikasi yang menghubungkan agen layanan dengan klien layanan perlu dibuat. Aplikasi ini memanfaatkan internet dan smartphone yang dapat diakses melalui aplikasi Android atau browser web. Pengembangan aplikasi ini menggunakan kerangka kerja Ionic React. Aplikasi ini dirancang dan dibangun menggunakan metode Waterfall yang terdiri dari pengamatan dan pengumpulan data, analisis, desain sistem, bangunan dan pengujian, kesimpulan dan saran.Dari desain dan bangunan yang telah dilakukan, dibuat aplikasi yang memiliki ftur dasar untuk antrean online. Aplikasi ini dapat dijalankan di browser web dan perangkat Android dengan sistem operasi minimum Android 4.4 KitKat.Abstract : Most public services in this era still use conventional systems. Which is, service clients get queue tickets, wait, and be served in the same place. This research aims to ease and enable people to queue remotely. Thus the time that is originally used to be spent waiting, could be used to be spent doing something else more useful. Based on the conditions said above, an application that connects service agencies with service clients needs to be made. This application utilizes the internet and smartphone which can be accessed through Android application or web browser. The development of this application uses the Ionic React framework. This app is designed and built using the Waterfall method consisting of observation and data collection, analysis, system design, building and testing, conclusion and suggestion.

Abstract

Abstrak : Distro X, merupakan salah satu vendor konveksi dan suvenir. Distro X menghadapi berbagai tantangan, salah satunya adalah kebutuhan untuk meningkatkan visibilitas usaha di dunia digital. Salah satunya adalah memiliki website untuk memperluas jangkauan pasar dan meningkatkan omzet penjualan, serta memudahkan platform pencarian. Dalam perancangan ini menggunakan kombinasi metode Design Thinking dan Lean Startup, yang dikenal efektif untuk desain UI/UX di industri kecil dan menengah. Pendekatan Design Thinking menekankan pemahaman mendalam terhadap kebutuhan pengguna dan memungkinkan terciptanya desain yang berfokus pada user experience. Sementara itu, metode Lean Startup memfasilitasi iterasi cepat melalui prototyping dan validasi berulang, sehingga menghasilkan solusi yang lebih adaptif dan relevan dengan kebutuhan spesifik industri kecil dan menengah yang memiliki sumber daya terbatas. Kombinasi kedua pendekatan ini terbukti mampu menghasilkan desain UI/UX yang tidak hanya user-friendly, tetapi juga efisien dalam hal pengembangan dan biaya. Proses perancangan ini melibatkan tujuh tahapan, yaitu emphatize, define, ideate, prototype, test, learn, dan release. Setiap tahapan dilakukan dengan tujuan mendapatkan pemahaman mengenai kebutuhan pengguna, mengembangkan ide-ide inovatif, serta menguji desain secara langsung. Hasil dari tahapan tersebut adalah sebuah desain UI/UX website yang siap untuk dikembangkan oleh developer. Desain ini diwujudkan dalam bentuk prototype simulasi website yang memudahkan visualisasi sebelum implementasi penuh. Berdasarkan hasil usability test, desain UI/UX ini dinyatakan layak dengan tingkat kelayakan sebesar 80,2%. Secara detail hasil ini merupakan rerata dari faktor Learnability 73.4%, Flexibility 76.5%, Effectiveness 82.16%, Attitude 88.6%. Persentase ini menunjukkan bahwa desain yang dihasilkan telah memenuhi standar kelayakan usability yang baik, mengingat standar rata-rata tingkat kelayakan usability yang diterima secara umum adalah sekitar 70-75%. Dengan demikian, hasil ini menunjukkan bahwa desain UI/UX DIstro X berada di atas rata-rata, sehingga layak untuk dikembangkan lebih lanjut. Hal ini juga mengindikasikan bahwa pendekatan kombinasi Design Thinking dan Lean Startup memberikan kontribusi signifikan dalam menghasilkan desain yang efektif dan memenuhi ekspektasi pengguna, khususnya di industri kecil dan menengah.====================================================Abstract : Distro X is a vendor specializing in garment and souvenir production. Distro X faces various challenges, including the need to enhance its digital visibility. One of the key initiatives is to establish a website to expand market reach, boost sales, and facilitate discoverability through search engines. The design process for the website employed a combination of Design Thinking and Lean Startup methodologies, which are recognized for their effectiveness in UI/UX design within small and medium enterprises (SMEs). The Design Thinking approach emphasizes a deep understanding of user needs and allows for the creation of user-centered designs, while the Lean Startup methodology facilitates rapid iteration through prototyping and repeated validation, leading to more adaptive and relevant solutions tailored to the specific needs of SMEs with limited resources.The combination of these two approaches has proven effective in producing UI/UX designs that are not only user-friendly but also efficient in terms of development and cost. The design process involved seven stages: empathize, define, ideate, prototype, test, learn, and release. Each stage was undertaken with the aim of gaining a better understanding of user needs, developing innovative ideas, and directly testing the design. The outcome of these stages was a UI/UX design for the website, ready to be developed by the developer. This design was materialized in the form of a simulated prototype to facilitate visualization prior to full implementation. Based on the usability test results, the UI/UX design was deemed feasible with an overall usability score of 80.2%. Specifically, this result represents the average of the following factors: Learnability (73.4%), Flexibility (76.5%), Effectiveness (82.16%), and Attitude (88.6%). This percentage indicates that the produced design has met the standard for good usability, considering the general benchmark for usability acceptance ranges between 70-75%. Thus, these results show that the UI/UX design for DIstro X surpasses the average, making it suitable for further development. This also indicates that the combination of Design Thinking and Lean Startup approaches contributes significantly to generating an effective design that meets user expectations, particularly in small and medium industries.
