Analisis Perbandingan VPN Tunneling Pada Multi-Cloud Untuk Optimalisasi Performa dan Skalabilitas
Multi-cloud infrastructure is increasingly being used in network service provisioning due to its ability to improve availability and reduce reliance on a single provider. However, the performance of VPN tunneling services in multi-cloud environments can vary significantly across providers due to differences in infrastructure characteristics, data centre locations, and network capacity. This study aims to compare the performance of SSH Tunneling and Xray VMess Non-TLS across five cloud providers, including DigitalOcean, UCloud Global, Biznet GioCloud, PT Media Antar Nusa, and CV Atha Media Prima. The method used was a comparative experiment with quantitative descriptive analysis, measuring four key metrics: latency, jitter, download throughput, and upload throughput, with each scenario repeated three times. The results show that Xray VMess Non-TLS outperforms in latency and upload throughput, with Biznet GioCloud recording the lowest latency at 31.30 ms and the most stable jitter at 7.00 ms, while PT Media Antar Nusa recorded the highest upload throughput at 62.60 Mbps. Conversely, SSH Tunneling demonstrated superiority in several download throughput scenarios, with PT Media Antar Nusa recording the highest value of 45.20 Mbps. These findings indicate that the selection of protocols and cloud providers should be tailored to the specific needs of the workload, and a multi-cloud approach offers significant flexibility in optimising VPN tunneling performance.

Prediksi Risiko Stunting Prakehamilan Menggunakan Sistem Pakar Certainty Factor Berbasis Mobile
Stunting still a serious public health issue, and the risk often originates as early as the pre-prenant phase. However, digital solutions that specifically integrate individual risk screening, expert-based reasoning, and mobile access for expectant mothers are still limited, which hinders the ability to effectively address the stunting risk during the critical pre-prenant phase. This study aims to develop a Certainty Factor-based expert system mobile application capable of independently, quickly, and educationally predicting the risk of stunting during the pre-prenant phase. This study employs a design and development research approach encompassing needs identification, knowledge acquisition, the formulation of a knowledge base and inference rules, system design, and mobile application implementation. The knowledge base was designed for three user categories: women in the pre-prenant stage, women who have given birth, and 19-year-old adolescents. Evaluation results showed that system performance varied across groups, with an accuracy of 0.67 for the adolescent and postpartum groups and 0.52 for the pre-prenant group. The precision and recall values also show a similar pattern, indicating that the system performs better in groups with more structured risk characteristics than in groups with more complex risk determinants. These findings suggest that the integration of a CF-based expert system with a mobile platform is not only capable of supporting the early detection of stunting risk but also provides an adaptive approach to differences in user characteristics, so that it has potential to increase the effectiveness of life-cycle-based screening.

Implementasi dan Pengujian Performa Server High Availability Menggunakan Metode Horizontal Scaling dengan Studi Kasus: Marketplace XYZ
Online marketplaces have become popular among the Indonesian public lately. This trend has an impact on the increasing visitor traffic, making the server's performance in handling requests heavier. Another impact that arises is the decline in web server performance accompanied by lag or network disruptions that cause web page responses to become slow. This issue can be addressed using load balancing, which is a method that distributes traffic across multiple servers to prevent load accumulation on a single server. Testing 10,000 requests with Apache Bench resulted in a response time of 7.725 ms for a server cluster (3 servers) using the round-robin algorithm. In comparison, the least connection algorithm produced a response time of 7.496 ms, while a single server resulted in 119.656 ms. In a stress test using JMeter with 10,000 requests, the server cluster produced a response time of 60 ms, while a single server resulted in 39.418 ms. In the failover implementation, load balancing works well in distributing requests to the available servers, ensuring that even during high traffic or server failures, the system maintains optimal performance and minimizes response times. Failover is the process of redirecting requests from a dead/broken server to another active server.

The calculation process is carried out by weighting each criterion and normalizing the data using the SAW method to determine the highest total score as an indicator of the best employee. The research results indicate that the application of the SAW method can produce objective, transparent, and efficient assessments, thereby assisting management in accurately determining high-performing employees. The implementation of this system is expected to enhance work motivation, strengthen the performance appraisal system, and support strategic decision-making within the company environment.

Perancangan Pembelajaran Online dengan Fitur Simulasi Tes Kerja Menggunakan Metode Simple Additive Weighting (SAW) pada SMK Ganesa Satria 2 Depok
Vocational High School graduates are required to have well-prepared work readiness to face competition in the industrial world. However, at SMK Ganesa Satria 2 Depok, the process of evaluating students' readiness through work test simulations is still conducted conventionally, making the assessment tend to be subjective and time-consuming. This research aims to design an online learning system that integrates a work test simulation feature by applying the Simple Additive Weighting method as a decision support system to evaluate student readiness. The system development method used is the Waterfall model, which includes requirements analysis, design, implementation, and testing. The SAW calculation is performed by considering criteria such as answer accuracy, completion speed, and understanding of basic concepts. The research results indicate that the system developed is capable of automatically processing simulation data and providing an objective ranking of student readiness. The implementation of this system is expected to assist the school in monitoring student progress and to make it easier for students to prepare for actual job selection processes.

Analisis Sentimen Kenaikan Pbb Berbasis Tiktok Menggunakan Support Vector Machine
The increase in Land and Building Tax for Rural and Urban Areas (PBB-P2) has generated diverse public reactions that are widely expressed through social media platforms. TikTok, characterized by high user engagement and informal communication patterns, provides a relevant medium for observing public sentiment toward fiscal policies. This study examines public sentiment regarding the PBB-P2 increase by applying a Support Vector Machine (SVM)–based classification approach. Two kernel configurations, Linear and Polynomial, are compared to identify differences in classification behavior when handling social media text data. User comments were collected automatically and processed through text cleaning, feature extraction, and sentiment labeling stages prior to model training. Model performance was analyzed using confusion matrix–based evaluation to observe prediction patterns across sentiment classes. The findings indicate noticeable differences in classification stability between the two kernel types, with the Linear kernel showing more consistent behavior when applied to imbalanced sentiment distributions. These results suggest that selecting a kernel aligned with the characteristics of textual data is an important consideration in social media–based sentiment analysis of public policy issues
