Data centers are major contributors to global energy consumption, with significant implications for operational costs and environmental sustainability. As energy demand increases, optimizing energy usage within these facilities has become essential. This study investigates the application of machine learning-based predictive analytics to enhance energy efficiency in data centers. By leveraging models such as Random Forest, Neural Networks, and Deep Learning, predictive analytics forecasts energy demands based on variables like temperature, workload, and time of day. Results from multiple case studies reveal that machine learning models can reduce energy consumption by up to 20%, offering a sustainable solution without compromising data center performance.

Blockchain technology presents a decentralized and transparent solution for secure voting systems. This paper provides a comparative analysis of consensus protocols, such as Proof of Work (PoW), Proof of Stake (PoS), and Delegated Proof of Stake (DPoS), to evaluate their effectiveness in a secure voting environment. Results show that PoS offers optimal security with reduced energy consumption, making it suitable for public elections.

PT Link Pasipik Indonusa Cabang Surabaya sebagai freight forwarder memiliki peran penting dalam proses impor muatan pestisida di jalur merah.

Hal ini diatasi dengan melakukan follow up kepada Bea Cukai; b) Delivery Order (DO) yang expired, dapat diatasi dengan meminta free time lebh lama ke pelayaran; c) Timbul SPTNP, dapat diatasi dengan melakukan penyesuaian harga; d) Karena pestisida termasuk ke dalam dangerous goods kelas 6.1, maka dalam penanganannya diperlukan perlakuan yang khusus, antara lain: dalam memindah drum yang berisi pestisida harus hati-hati, tutup yang telah dibuka karena diambil sampelnya harus ditutup dengan rapat, lalu membuka drum yang berisi pestisida harus di ruang tertutup agar terhindar dari matahari.

Python programming language is a popular programming language in the field of data analysis. In this research, researchers will analyze data on the cause of lung cancer, because lung cancer has the highest death case among other cancer types. The purpose of the research is to explore how dataset processing related to lung cancer-causing factors using the Python programming language and the datasets used are derived from Kaggle. The research method used is quantitative with a population of 462,000 people and a sample of 999 people. The analysis technique used is an explorative data analysis technique. From the results of the research, the highest cause of lung cancer was found in people aged 32-42 years, level 7 genetic factor, 7th level in dust allergies, level 7 obesity and male sex has higher risk than women.
 

<p style="text-align: justify;"><strong>Abstract. </strong><em>Long-distance relationship are common on these day. Based on the latest data from the Central Statistics Agency for 2015 in Indonesia, especially in the North Sulawesi province there were 35.851.00 individuals who migrated outside the region and lived separately from their families.

Student satisfaction at a university could predict the continuity of the university. Therefore understanding and improving student satisfaction needs to be done. This study provides an alternative model of student satisfaction instruments at private universities. The research methodology consists of a series of literature reviews, interviews, expert validation and testing the validity of the instrument using the Rasch model. The respondents of this study were 543 students from 6 faculties in a private university. Research findings include: (1) student satisfaction instrument models; (2) items that are difficult to approve; and (3) items perceived differently based on respondents' demographics. This research has implications for the management of private universities to improve some domains of student satisfaction.
