Server monitoring is the process of monitoring server system resources such as monitoring server performance also helps identify other performance-related problems such as resource utilization, application downtime, and response time to a service. File Integrity Monitoring (FIM) is the activity of monitoring the integrity of a file to maintain the integrity of a file from unauthorized changes, by utilizing Wazuh as one of the open source applications to monitor has various features to perform monitoring. Computer network security becomes something that needs to be considered as technology develops rapidly. It is the responsibility of a network administrator to monitor system security at any time. Given the various threats that can enter the system at any time, an application is needed that can detect and prevent the threat in real time. The problem raises the idea for the author to utilize one of the applications, namely Suricata in which there is an IDS (Intruction Detection System) method that will serve as an attacker detection. Suricata will display an alert when there is a suspicious package. The resulting alert will be stored in the file log. Then the log will be displayed on the Wazuh web interface. Alerts that appear on Wazuh will be sent to network administrators via e-mail

According to UU No. 26 of 2007, zoning laws are one of the mechanisms for regulating spatial usage. Supporting tools that are in line with the characteristics and social dynamics of the community are required, specifically through the development of mobile applications, in order to increase public awareness of how space is used and the active participation of the community in monitoring the use of space. The Global Positioning System (GPS) output on an Android mobile device will be compared with the zoning area using this application. Map-Matching, which compares the path geometries of two sources, is the technique employed. using adapting the projected raw position using GPS to the closest zoning segment, the Map-Matching method matches maps. This application is intended to provide information on spatial use zoning regulations, which include clauses governing the use of space and the space envelope that must, may, and may not apply. On the basis of the Payakumbuh City Detailed Spatial Plan (RDTR), application testing was done there. This program uses a map matching method to determine coordinates for spatial use zoning and has a responsive web client server approach

Conventional PDAM water meter systems, which often employ post-paid techniques, frequently lead to payment delinquencies, challenges in consumption regulation, and delayed leak detection. This study creates a prototype of an IoT-enabled prepaid water meter system utilizing the ESP32 microcontroller, YF-S201 flow meter sensor, TDS sensor for water quality assessment, and a relay-operated solenoid valve, combined with a PHP/MySQL website hosted on AWS Academy for digital token transactions and remote monitoring. The technique employs a Research and Development (R&D) framework including analysis, design, implementation, and testing phases. The test findings indicate that the system efficiently conducts real-time monitoring of water consumption and quality while successfully addressing payment arrears; nevertheless, a significant constraint is present in the solenoid valve, which produces an insufficient water flow, failing to satisfy typical home flow rate requirements. The prototype has significant promise for updating PDAM water distribution by offering transparency and comprehensive control to consumers; however, enhancements to the solenoid valve components are necessary before practical adoption

The rapid advancement of language-based artificial intelligence, particularly Large Language Models, has enabled the development of adaptive and context-aware virtual assistants. This research aims to develop an interactive chatbot for Politeknik Negeri Padang utilizing the Sahabat-AI model (Gemma2 9B CPT), a large-scale model specialized in Bahasa Indonesia and local dialects (Javanese, Sundanese), combined with the Retrieval-Augmented Generation (RAG) method to enhance document-based answer accuracy. The system architecture integrates a Streamlit-based user interface supporting text/voice input and multilingual output, an automated web-scraping module using Scrapy to update institutional data, a structured knowledge base in Supabase, and a semantic vector search with FAISS. The development process followed a systematic design and implementation approach, with the RAG pipeline incorporating all-indo-e5-small-v4 embeddings to ensure semantic relevance. Performance evaluation using LangSmith demonstrated that Sahabat-AI outperformed Llama 3, achieving an average score of 0.84 (correctness: 0.89, relevance: 0.90, groundedness: 0.80, retrieval quality: 0.77) in Indonesian language testing. The chatbot exhibited strong local language understanding, scoring 0.74 for Javanese and 0.71 for Sundanese, while reducing hallucinations through RAG integration. Black-box testing confirmed the reliability of multimodal features such as speech-to-text and text-to-speech. The findings contribute to the development of the first Sahabat-AI–based multilingual chatbot for Politeknik Negeri Padang, integrating automated document retrieval and embedding pipelines for efficient information services.
