Abstract

The online gaming platform Roblox has become a significant player in the gaming industry, providing a space for user-generated content. Predicting the popularity of Roblox games can help developers design better games and optimize user engagement. This study explores the use of machine learning models to predict the popularity of games on Roblox using gameplay features and metadata. A dataset of 9,734 games was collected, including variables such as likes, visits, game age, and active players. Three machine learning models, Decision Tree, Random Forest, and Gradient Boosting were employed to predict the number of favorites, which serves as a proxy for game popularity. Among the models tested, Gradient Boosting outperformed the others, achieving the highest R-squared score (0.85) and the lowest Root Mean Squared Error (11,470). Key features such as likes, game age, and visits were identified as the most influential in predicting game popularity. Based on these findings, this study recommends that developers focus on features that increase player engagement, such as regular updates and optimizing game exposure. Additionally, incorporating additional data sources, such as user reviews, and exploring explainability methods like SHAP can further improve model accuracy and transparency. This research contributes valuable insights into how machine learning can support decision-making in the development and optimization of Roblox games.

Abstract

Kemampuan menulis ilmiah merupakan keterampilan esensial bagi dosen di bidang data science untuk meningkatkan produktivitas dan kualitas publikasi di jurnal internasional bereputasi.. Permasalahan utama yang dihadapi oleh dosen di Fakultas Ilmu Komputer Universitas Amikom Purwokerto adalah kurangnya keterampilan dalam menulis artikel ilmiah yang memenuhi standar jurnal internasional, yang berdampak pada terbatasnya publikasi mereka. Sebagai solusi, kegiatan pengabdian ini menyelenggarakan pelatihan dan pendampingan penulisan artikel ilmiah dengan tujuan untuk meningkatkan kapasitas dosen dalam menulis secara sistematis dan sesuai standar jurnal internasional. Workshop interaktif yang diadakan diikuti oleh 25 dosen dari empat program studi, dengan sesi teori, praktik langsung, dan peer review. Hasil evaluasi menunjukkan peningkatan signifikan pada kemampuan peserta: aspek struktur penulisan meningkat dari 60% menjadi 80%, bahasa ilmiah dari 58% menjadi 82%, serta pemahaman standar jurnal dari 52% menjadi 76%. Selain itu, 8 peserta berhasil menghasilkan draf artikel yang siap disubmit ke jurnal internasional. Kegiatan ini juga berhasil mendorong terbentuknya komunitas penulis ilmiah yang menjadi langkah awal dalam membangun budaya akademik kolaboratif secara berkelanjutan di Fakultas Ilmu Komputer.

Abstract

The rapid growth of Artificial Intelligence (AI) industries worldwide has increased the demand for skilled professionals and highlighted the need to understand salary determinants in this sector. This study aims to analyze the factors influencing the compensation of AI professionals globally, with a particular focus on the effects of company location, experience level, and required technical skills. Using a dataset of 15,000 AI job postings collected from multiple countries, a Multiple Linear Regression (MLR) model was developed to identify predictive relationships between independent variables—location, experience, and skills—and the dependent variable, annual salary in U.S. dollars. Data preprocessing included one-hot encoding for categorical variables, standardization of numerical attributes, and vectorization of text-based skill descriptions. Model evaluation produced strong predictive results, with an R² of 0.82, a Mean Absolute Error (MAE) of 18,677 USD, and a Root Mean Squared Error (RMSE) of 25,704 USD. Statistical tests confirmed that company location and experience level significantly affected salary outcomes (p 0.05), while technical skills contributed only marginally. These findings suggest that structural factors such as geography and seniority play a more decisive role in determining AI salaries than specific technical competencies. The study concludes that MLR offers a transparent and interpretable analytical framework for exploring salary disparities in the global AI workforce. The results provide practical implications for organizations designing fair compensation policies, professionals assessing market value, and educators aligning training programs with evolving industry demands.
