Abstract

The growing demand for energy-efficient and sustainable solutions has positioned Green IT-based cloud computing as a pivotal strategy for technology companies aiming to balance operational efficiency with environmental stewardship. This study conducts a systematic literature review of 15 Scopus-indexed documents to explore the benefits, challenges, and strategies associated with the adoption of Green IT-based cloud computing. The findings reveal that these practices significantly enhance energy efficiency, reduce operational costs, and minimize carbon footprints. However, challenges such as high implementation costs, technological complexity, and intermittent renewable energy sources impede widespread adoption. Strategies including the use of AI and machine learning, collaborations with renewable energy providers, and the establishment of standardized policies are identified as effective solutions. This study contributes to the growing discourse on sustainable IT practices and provides a roadmap for technology companies aiming to integrate Green IT principles into their cloud computing operations.

Abstract

This study aims to optimize the performance of fuel-injected motorcycles through the application of a Deep Neural Network (DNN) in the Electronic Control Unit (ECU) and the use of ethanol-pertalite fuel blends. The ethanol blends used in the study were 0%, 5%, 10%, 15%, and 20%. Fuel consumption tests were conducted using the standard ECE/324 driving cycle, and emission tests were performed according to Euro 4 standards. Tests were conducted on a real track to evaluate fuel consumption performance and exhaust gas emissions. The results indicate that the 15% ethanol blend (E15) provided optimal engine efficiency, while the 20% ethanol blend (E20) resulted in the largest reduction in carbon monoxide (CO) and hydrocarbon (HC) emissions. Furthermore, the DNN model with 50 neurons and a Sigmoid activation function demonstrated the best balance between accuracy (R=0.9868) and generalization (MSE=0.3843) in optimizing ignition timing and injection timing. In conclusion, the ethanol blends and the application of DNN in the ECU have proven effective in enhancing fuel efficiency and reducing exhaust emissions, supporting the development of more sustainable transportation technologies.

Abstract

Penelitian ini bertujuan untuk mengembangkan sistem pakar yang mampu mendiagnosa gangguan somatisasi menggunakan metode K-Nearest Neighbors (KNN). Gangguan somatisasi merupakan kondisi psikologis yang sulit didiagnosis karena gejalanya yang bersifat fisik namun berasal dari masalah psikologis. Ketidakjelasan gejala ini sering kali mengarah pada pemeriksaan medis yang tidak diperlukan dan mahal, menambah beban bagi pasien dan sistem kesehatan. KNN dipilih karena kemampuannya untuk melakukan klasifikasi dengan membandingkan data uji dengan data pelatihan berdasarkan kedekatan menggunakan Euclidean Distance. Euclidean Distance digunakan untuk mengukur jarak terpendek antara dua titik dalam ruang fitur, yang dihitung dengan mengakar kuadrat dari jumlah perbedaan kuadrat antara nilai-nilai fitur dari dua titik tersebut. Hasil penelitian menunjukkan bahwa sistem pakar yang dikembangkan memiliki akurasi yang tinggi, yaitu mencapai 92,5%, yang mengindikasikan bahwa metode KNN dengan Euclidean Distance efektif dalam mendiagnosa gangguan somatisasi. Faktor-faktor seperti pemilihan nilai K yang optimal dan normalisasi data berperan penting dalam keberhasilan sistem ini. Kontribusi signifikan dari penelitian ini adalah pembuktian bahwa KNN dapat diimplementasikan secara efektif dalam sistem pakar untuk mendukung tenaga medis dalam melakukan diagnosis gangguan somatisasi dengan akurasi yang tinggi dan keandalan yang baik.
