Abstract

Earthquakes are natural disasters that can severely affect human lives and infrastructure. This study aims to analyze and evaluate the effectiveness of the C4.5 decision tree algorithm in predicting earthquakes based on historical seismic data. Using a quantitative approach and systematic literature review, the study compiles information from previous research related to earthquake prediction models. The results suggest that the C4.5 model provides reasonably high prediction accuracy in earthquake-prone areas and could be integrated into early warning systems.

Abstract

In order to meet the needs of life, work is a very basic field in order to get money to meet the needs of life. With the development of the business world in the era of globalization, the breadth of opportunities and diversity of jobs offered, especially in the field of Information Technology (IT). This situation makes Informatics students of the University of Muhammadiyah Jambi confused in choosing future careers. One method that is relevant and has a consistency value calculation in determining the priority level of criteria is the Analytical Hierarchy Process (AHP) method. This study aims to build a Decision Support System website using the AHP method. The results showed a consistency ratio value of 0.06249 which means less than the consistency ratio value used in the AHP method, which is 0.1, so that the calculation results are valid, and can be used. The final result of this application provides a decision recommendation that BRI is the most ideal state-owned company in the career choice of UMJ Informatics students with a value of (0.544258) followed by PLN (0.239861), Telkom (0.149692) and Pertamina (0.066188). These results are obtained from the calculation of priority criteria and alternatives using the AHP method.
Studi Literatur Review Sistem Terdistribusi Keamanan Data Berbasis Blockchain Anisa Rizki Septia; Hetty Rohayani

Abstract

Sistem terdistribusi sering menghadapi tantangan keamanan yang kompleks, seperti akses tidak sah dan manipulasi data. Teknologi blockchain dengan karakteristik desentralisasi, transparansi, serta kriptografi menawarkan solusi efektif terhadap permasalahan tersebut. Penelitian ini bertujuan untuk menganalisis penerapan blockchain dalam meningkatkan integritas dan keamanan data pada sistem terdistribusi melalui metode Systematic Literature Review (SLR). Analisis dilakukan terhadap 15 literatur terpilih yang diterbitkan pada rentang tahun 2019–2024. Hasil penelitian menunjukkan bahwa blockchain mampu meningkatkan keamanan data dengan menghilangkan ketergantungan pada otoritas terpusat dan menjamin validitas transaksi melalui mekanisme konsensus. Meskipun demikian, tantangan seperti skalabilitas teknis dan kompleksitas implementasi masih menjadi hambatan utama. Penelitian ini diharapkan dapat menjadi referensi dalam pengembangan sistem terdistribusi yang memerlukan tingkat keamanan tinggi.
