Abstract

PT. Sridatta Prastama Telecommunications (PRASTATEL) as a company in the field of telecommunications service providers must provide non-stop cell phone / VoIP servi-ces. Devices that work 24 hours non-stop by minimizing the damage that occurs, must be supported by monitoring to ensure the system is running properly. If there is a sig-nificant increase in temperature, it can affect system performance or cause damage to the hardware side. The cooler in the server room is felt to be not optimal because the cooler is often constrained by frequent power outages or the cooler turns off and avoids suspicious activities / activities that occur in the server room because the server room administrator is not always on site. From the problems described above, a solution is needed to monitor the system remotely. So that the system is able to know changes in room temperature (Monitoring) in real time and monitor whether there is activity oc-curring in the server room. By using Internet of Things (IoT) technology, the NO-DEMCU ESP-8266 device and the fuzzy logic method which basically maps an input space into an output space that is applied to the server room temperature sensor. This monitoring system uses the Telegram application to receive notifications in the form of text or images. So that it can monitor temperature changes and activities that occur in the server room in real time and accurately. Therefore the server room administrator does not have to be on the site.

Abstract

English vocabulary pronunciation is one of the important aspects that must be mastered by English learners. However, many people in Indonesia face difficulties in mastering basic vocabulary pronunciation, which can hinder their progress in the early stages of learning speaking and listening. Mistakes in pronunciation often cause ineffective communication, making the message difficult for the other person to understand. Even at the level of learners who have memorized many vocabularies and are able to have simple conversations, mispronunciation remains a significant obstacle and often hinders smooth communication. To address this challenge, this study aims to develop an application based on speech processing technology and Natural Language Processing (NLP) that is specifically designed to provide pronunciation correction for selected vocabulary. This application focuses on mastering the pronunciation of 500 basic vocabulary as a companion for learning speaking and listening at an early stage. This application does not only aim to memorize vocabulary, but also helps users learn to pronounce each word correctly. With this approach, users can get real-time corrective feedback for each vocabulary spoken, allowing them to correct mistakes directly and gradually improve their speaking ability. In addition, the application provides pronunciation analysis supported by speech processing technology to recognize and analyze user pronunciation errors, while NLP is used to provide relevant assessments and improvement suggestions automatically. The results of the study show that this application is effective in helping learners improve their pronunciation of basic vocabulary. By focusing on frequently used basic vocabulary, this application helps users improve their speaking skills more easily. This application is also a tool that supports independent learning for users, thereby increasing their confidence in speaking English. This study is expected to be a solution that supports more effective and affordable English learning, especially for beginners in Indonesia who want to start mastering speaking and listening with a stronger foundation.

Abstract

This research aims to address the issue of uneven bandwidth distribution in large organizational networks by implementing Quality of Service (QoS) using FIFO and the Hierarchical Token Bucket (HTB) algorithm on Mikrotik routers. Uneven bandwidth distribution can disrupt productivity and operational efficiency. This study creates a fair and efficient traffic management system, allowing bandwidth allocation according to user needs. The methodology involves detailed configuration of Mikrotik RouterOS to optimize QoS with adjusted HTB settings. Testing was conducted using IPerf3 to measure bandwidth variations received by clients in different conditions, including scenarios with two and three active clients. The results indicate that the HTB method provides more stable and consistent bandwidth distribution compared to FIFO. In the two-active client scenario, the unused bandwidth by the third client is allocated to higher priority clients, demonstrating HTB's effectiveness in managing traffic priorities. This research is expected to enhance user satisfaction by providing a network that is both stable and responsive to the needs of various operational applications, and contribute significantly to the development of best practices for bandwidth management in complex organizational environments.
