Abstract

Pesatnya perkembangan e-commerce menghadirkan tantangan berupa banyaknya pilihan produk yang dapat menimbulkan information overload bagi konsumen. Untuk mengatasi permasalahan tersebut, penelitian ini mengembangkan sistem rekomendasi produk berbasis Content-Based Filtering dengan Cosine Similarity. Metode ini memanfaatkan kombinasi fitur teks (judul dan deskripsi produk) yang direpresentasikan dengan TF-IDF, serta fitur numerik (harga, rating, dan jumlah rating) yang dinormalisasi menggunakan StandardScaler. Selanjutnya, seluruh fitur digabungkan dan dihitung tingkat kesamaannya dengan cosine similarity untuk menghasilkan rekomendasi produk yang relevan. Hasil penelitian menunjukkan bahwa pendekatan ini mampu memberikan rekomendasi yang logis, di mana produk dengan spesifikasi serupa ditampilkan secara berurutan berdasarkan tingkat kesamaan. Analisis tambahan juga memperlihatkan bahwa mayoritas produk memiliki rating tinggi meskipun harga bervariasi, menunjukkan harga bukan satu-satunya indikator kualitas. Dengan demikian, sistem ini terbukti efektif membantu konsumen dalam menemukan produk sesuai preferensi sekaligus memberikan insight bagi pelaku e-commerce.

Abstract

Teknologi Informasi (TI) menjadi esensial dalam operasi bisnis modern, mempengaruhi daya saing, efektivitas, dan efisiensi organisasi. Keberhasilan tata kelola TI terletak pada kesesuaian dengan tujuan organisasi dan adaptasi terhadap perubahan teknologi. COBIT 2019, sebuah framework yang membantu manajemen bisnis dalam mengelola TI, menjadi kunci dalam memandu strategi pengembangan. Penelitian di Dinas Kominfo Sulawesi Utara menemukan tiga proses prioritas: APO12 - Managed Risk, DSS01 - Managed Operations, dan DSS05 - Managed Security Services. Hasil penelitian menunjukkan tingkat kapabilitas dan keefektifan masing-masing proses, dengan APO12 berada pada kapabilitas level 2 dan rating 66%, DSS01 pada level 4 dengan rating 83%, dan DSS05 pada level 2 dengan rating 84%. Evaluasi ini memberikan wawasan yang berharga untuk meningkatkan kinerja dan keamanan TI di institusi tersebut, serta memastikan kontribusi TI yang optimal terhadap tujuan organisasi. Dengan demikian, pemahaman yang mendalam tentang aspek TI yang spesifik dan perannya dalam konteks bisnis lokal menjadi kunci dalam mengambil langkah-langkah yang relevan dan efektif dalam pengelolaan TI.

Abstract

This community service activity aims to introduce information technology to students in grades 1 to 3 at SD Madison School Mobuya. Through an interactive workshop approach, students were introduced to information technology tools and basic computer components. A total of 28 students participated in this activity, starting with a pretest to assess their initial understanding of technology. The pretest results showed that 80% of students were not familiar with technological tools and 90% were not familiar with the parts of a computer. After participating in the educational sessions, the posttest results revealed that all students had gained a solid understanding of information technology tools and basic computer components. This activity proves that early introduction to information technology can improve students' understanding of technology and equip them with basic skills needed to face the challenges of the digital world. It is hoped that this activity can be replicated in other schools to broaden the positive impact on the development of technology literacy among students.

Abstract

This research focuses on analyzing the global company market capitalization dataset using the FP-Growth algorithm combined with a load-balancing constraint approach. The main objective is to identify association patterns among different market capitalization categories Small, Medium, Large, Mega, and Ultra to understand their distribution and interrelationships. The study begins with data preprocessing, cleaning, and categorization of companies based on their market values. The FP-Growth algorithm is applied with a minimum support threshold of 0.02, and a load balancing constraint is introduced by filtering rules with support ≥ 0.05 and lift > 1, ensuring balanced and significant association patterns. The analysis results show that the most dominant categories are Medium and Small, representing the majority of companies worldwide, while Large, Mega, and Ultra categories are relatively rare. The strongest rule indicates that countries with “Large” companies are very likely to also have “Small” and “Medium” companies. Evaluation metrics show an average lift of 1.171 and an average confidence of 1.000, confirming strong and reliable associations. Overall, this study provides insights into global market capitalization patterns and demonstrates the effectiveness of FP-Growth with constraints in revealing meaningful, balanced relationships within large-scale business data.   Keywords – FP-Growth, Load Balancing Constraint, Market Capitalization, Association.

Abstract

At Klabat University, the conventional method of deducting Sabbath points poses challenges for students and supervisors due to its inefficiency. To address this, the GREENPOIN smartphone application was developed as an innovative solution for managing Sabbath points. The application enables administrators to approve point redemptions, add supervisors, manage tasks, and monitor students' total Sabbath points. Students earn points by completing environmental cleaning tasks assigned by supervisors. The system was designed using prototype models and use case diagrams to evaluate user requirements. Key features include Mission Management and Validation for supervisors; Supervisor Management, Point Management, and Point Redemption Approval for administrators; and Login, Registration, Point Viewing, Mission Viewing, Task Submission, Point Redemption, History, and Point Reset for students. GREENPOIN has proven to enhance the efficiency of Sabbath point management, accelerate task validation, and streamline mission oversight. The application increases process transparency and encourages student participation in campus cleanliness initiatives. Future enhancements will include push notifications, an iOS version, mission-specific comments, and API integrations, such as Google Maps, to further improve functionality.
