Abstract

Programming through computer technology in this day a rapid growth experience. This shows a tendency that led to the creation and development of an automated technology means a more practical, efficient and economical to facilitate and accelerate all human activity. The spread of information technology, which is less than optimal and uneven, felt weakness in the agency's workforce and East Manggarai district, especially in the data collection job seekers. Where many job seekers are difficult to list themselves as job seekers in the Department of Workers and East Manggarai Circle. This study describes how application data collection job seekers at the Department of Labor and Transmigration East Manggarai Regency, who design a new information system based sites for data capture job seekers in the solution of the problems faced by the office of the Department of Labor Aims, and emigration East Manggarai district. The collection of data obtained by conducting library research, interviews and observations. The result of this research is a web-based application searcher data capture job. Vocational training and job information for job seekers These applications can be easily accessed by anyone who wanted to gain employment as a job in East Manggarai district to win.

Abstract

badi Collection Shop is a business entity engaged in the sale of clothing located on the roadRoundabout PU Tuak Daun Merah II. In conducting its business processes the Abadi Collection Shopstill uses the conventional mechanism, the customer must come directly to the outlet to see and searchfor products sold by Abadi Collection Shop. In order to support the business run by Abadi CollectionShop, the existence of customers is not only a source of company income but also as a long term assetthat needs to be managed and maintained through Customer Relationship Management. The purposeof this research is to design and build an Application Service E-commerce Web Based Clothing Salesby applying Customer Relationship Management at Abadi Collection Shop. Data collecting method bywriter is literature study, observation and interview, tool of analysis of system design in the form ofdocument flow, context diagram, data flow diagram, and proposed database of entity relationshipdiagram. While making the software in this thesis, the writer uses PHP and Adobe Dreamwaver CS6and MySQL database. The results of this study system designed to support order transactions as wellas a promotional event that can facilitate customers in communication and provide input for AbadiCollection Shop.

Abstract

The escalating complexity of computer networks and cybersecurity threats demand analytical approaches capable of systematically and measurably representing network structure. Discrete mathematical graph theory offers a formal framework for modeling network topology as nodes and edges, thus potentially supporting more effective intrusion detection and firewall placement optimization. This research aims to conduct a Systematic Literature Review of publications from 2022–2026 to identify graph theory applications in intrusion detection, evaluate the most effective graph-based firewall optimization methods, and map research gaps and future development trends. The methodology employed follows the SLR protocol with stages of systematic search across reputable databases, selection based on inclusion-exclusion criteria, and analysis through descriptive-comparative meta-analysis, thematic meta-synthesis, and content analysis. Results show the dominance of weighted graphs and structure-based learning approaches for network anomaly detection, as well as firewall optimization modeling through integer linear programming and graph heuristics. This research contributes to presenting an integrated synthesis between intrusion detection and firewall optimization within discrete graph framework, and provides conceptual foundation for developing adaptive network security models based on mathematical structure.
