Abstract

The application of Team Viewer application technology is one of the digital innovations to remotely control computers/laptops. The population of this training is all students of class X and XI Computer Network Engineering of SMK Swasta Cerdas Bangsa, North Sumatra Province, Deli Serdang Regency, totaling 40 students, while the sample of this study was taken from a population of 20 students. The sampling technique used is the purposive sampling technique. The practical technique used in this training is direct observation of the activity process and observations carried out directly by students during the practicum activities. The technique used by students is the number of students divided into 20 groups, 1 group of 2 people and each group must register on the teamviewer application in order to be able to log in to the application so that the process of implementing the practicum is successful. TeamViewer software is one step in helping students carry out practicum activities online. This training aims to determine students' understanding in implementing TeamViewer software. The purpose of this study was to determine how the process of implementing TeamViewer software is and to see students' responses to the results of using TeamViewer in practicum activities for the subject of Computer Network Systems. Based on the results of the training carried out, it is known that the implementation of the computer network system subject practicum can be carried out well by looking at the results of the observation of the implementation of activities at a percentage of 100% and the results of the observation of the use of the Teamviewer remote desktop application in the implementation of the implementation are also at a percentage of 100%. Thus it can be concluded that the implementation of remote practicums can be carried out by utilizing the Remote Desktop Teamviewer application.

Abstract

Population administration at the Tanah Merah Village Office, Pasir Penyu District, previously relied on conventional records that created duplicate data, inconsistent information, slow retrieval, and delayed report preparation. This study designed and implemented a web-based population data processing information system using observation, interviews, literature review, and the waterfall development model. Requirements were translated into use-case, activity, and class diagrams and a MySQL database. The implemented PHP-based system provides administrator authentication, user management, population and destination records, move-out requests, online birth-certificate registration, death-certificate registration, monitoring, document-completeness checks, and service outputs. Black-box testing covered seven navigation and data-management scenarios. All seven scenarios produced the expected results, yielding a 100% pass rate within the documented test scope. The system centralizes village records, reduces dependence on physical archives, and supports faster retrieval and reporting. Further work should evaluate usability, security, data validation, interoperability with higher-level civil-registration services, and operational performance after deployment.

Abstract

The wireless network at SMP Swasta GKPS I Raya Simalungun initially depended on a single modem/router installed in the administration room. Its corner position and concrete-wall obstructions produced uneven signal distribution and blank spots in several school areas. This study analyzed the existing condition and developed an optimized network configuration using the Network Development Life Cycle (NDLC). Cisco Packet Tracer supported logical design and simulation, while TP-Link access points and a MikroTik hAP lite router were configured for addressing, wireless service, routing, firewall functions, and queue-tree bandwidth management. The implementation expanded service planning to the principal's office, administration area, library, teacher room, and computer laboratory. Configuration verification confirmed successful router access, static addressing, SSID and channel definition, LAN integration, MikroTik management, and queue-tree activation. The resulting design provides a structured basis for fairer bandwidth distribution and continuous monitoring, although future work should add quantitative measurements of coverage, throughput, delay, jitter, packet loss, and user experience.

Abstract

Manual student admission at SMP Swasta Taman Siswa Sugarang Bayu required applicants and parents to visit the school, while staff recorded and searched paper forms. This study developed a web-based admission information system using a user-centered design procedure to align its functions with applicant and administrator workflows. The procedure covered understanding the context of use, specifying user requirements, producing design solutions, and evaluating the implemented functions. The system was modeled with Unified Modeling Language, implemented with Bootstrap and MySQL, and organized into applicant and administrator modules. Applicants can register accounts, authenticate, complete biodata, enter report-card scores, and print documents; administrators can manage users, menus, information, applicant records, scores, and contacts. Black-box testing across seven navigation and transaction scenarios produced seven successful outcomes (100%), with no broken links observed in the tested workflow. The system therefore provides a functional digital alternative to the former paper-based process. Because the evaluation was limited to functional verification, future work should quantify effectiveness, efficiency, satisfaction, accessibility, and security with representative users and deployment data.

Abstract

Raskin and social assistance data processing in Kutambaru Village, Munte District, Karo Regency, had relied on manual records that were vulnerable to human error, inconsistent entries, fragmented information, and slow report retrieval. This study aimed to design, implement, and functionally validate an information system developed in PHP that integrates population, household condition, demographic, and assistance data within an administrative environment. The system was developed using the waterfall model through requirements analysis, system design, implementation, testing, deployment preparation, and maintenance planning. Requirements were obtained through observation, document examination, and discussion with a prospective village office user, then translated into flowcharts, data flow and context diagrams, relational database structures, and interface modules. The resulting application provides administrator authentication; population, housing, and hamlet data entry; public program information and beneficiary searches; demographic summaries; an administrative dashboard; population and assistance classification; and printable reports. Functional validation was conducted directly with one prospective end user from the Kutambaru Village Office. Within this limited validation scope, the user confirmed that the documented functions operated in accordance with operational needs. The findings indicate that the application can centralize dispersed records, support more consistent data retrieval, and improve the organization of assistance administration. Nevertheless, the study does not establish targeting accuracy, usability across users, security robustness, or long term administrative impact. Future development should therefore formalize eligibility criteria, implement access controls and audit trails, expand structured testing scenarios, and evaluate processing time, data quality, user satisfaction, and beneficiary targeting outcomes after deployment.
