Abstract

The electrospinning method is a method of making nanofibers using the influence of an electric field to produce a jet of electrically charged polymer solution. In this experiment, polyvinyl alcohol (PVA) nanofibers and ketapang leaf extract with various viscosities were made using electrospinning equipment with a static collector. Scanning using an electron microscope (SEM) shows that the morphology of the nanofibers formed looks homogeneous, continuous, and without beads (beads free). The SEM results were analyzed using ImageJ software, which was then carried out using Origin software to determine the fiber diameter. Diameter size distribution with fiber diameter size distribution ranging from 2000 to 8000 nm.

Abstract

Dr. Tengku Mansyur Regional Hospital, Tanjungbalai City, still has difficulty in grouping the intensity of diseases that often occur in Tanjungbalai City, in the exact grouping based on the results of patient medical data records. Medical records are documents that record information about the patient's condition, medical history, and previous treatment filled in by health workers who provide care and treatment. Medical records function to provide health information for all health workers involved in patient care. The goal is to minimize the increase in the intensity of the disease experienced by patients by providing counseling and solutions to diseases that have high intensity. administration in an effort to improve health services in hospitals and also increase the supply of drugs according to the drugs needed. This study uses the Jupyter Notebook application based on Python and data mining methods, especially the K-Means Clustering algorithm, to analyze patient medical record data based on age, blood pressure and disease diagnosis. With the K-Means Clustering Algorithm, it can also minimize variation in one cluster and maximize variation between clusters. With the research, Cluster C1 is a disease that often occurs with high intensity and has 49 members, Cluster C2 is a disease that occurs with intensity. Cluster 2 has 28 members, while Cluster C3 is a disease that occurs with low intensity and has 23 members.

Abstract

A reliable and efficient WiFi network is a crucial facility to support the activities of passengers and visitors at Kualanamu International Airport. This study aims to identify issues affecting WiFi network performance and provide optimization solutions based on technical analysis and user needs. Data collection was conducted by measuring network parameters such as throughput, delay, jitter, and packet loss across various strategic airport areas, including waiting rooms, departure terminals, and commercial zones. The analysis revealed key challenges, such as high user density during peak hours and uneven access point distribution. To address these issues, the study proposes optimization steps, including bandwidth capacity expansion, reconfiguration of network devices, and the adoption of advanced technologies like WiFi 6. Implementing these recommendations is expected to enhance the quality of the WiFi network at Kualanamu International Airport, improve user experience, and support overall airport operations effectively.

Abstract

PT. Labani faces challenges in improving the efficiency and flexibility of its application development service sales process. The traditional methods used so far have been inadequate in accommodating clients' changing needs quickly and efficiently. This research aims to address these issues by implementing the Agile Scrumban method, which combines the strengths of Scrum and Kanban. The study was conducted through a case study approach with qualitative methods, including direct observation, in-depth interviews with sales and development team members, and analysis of internal company documents. The implementation of Agile Scrumban began with intensive training for the team, followed by gradual application in sales and application development projects. The research results indicate that Agile Scrumban successfully improved inter-team coordination, reduced project lead time, and provided better visibility into sales and development progress. Issues such as team adjustment to the new method and synchronization between sales and development were addressed through ongoing training and enhanced communication. Thus, the implementation of the Agile Scrumban method at PT. Labani proved effective in resolving efficiency and flexibility issues and increasing customer satisfaction. Recommendations for the company include additional training and strengthening inter-departmental integration to ensure the smooth adoption of this method.

Abstract

The aim of this research is to determine the role of teachers and parents in implementing education for children with special needs (children with special needs) at school. This research uses a qualitative descriptive research method. Data collection techniques include: observation and interviews. The research subjects or informants were the school principal, class teacher/homeroom teacher and student parents. Collaboration between parents and teachers is very necessary in the formation and improvement of inclusive education. The research results show that: (1) In inclusive education, the role of the principal as the highest decision holder in an institution greatly influences the direction and goals to be achieved by the institution. (2) There are many factors inhibiting the management of inclusive education at SDN Talang Pantai from the beginning of management until now. The role of the teacher/class teacher is very important in learning, namely the teacher always provides motivation when starting the teaching and learning process, the teacher always pays more attention to children with special needs compared to other normal children and the teacher/class teacher always guides children with special needs when carrying out ongoing learning. (3) Efforts made by parents towards children with special needs, namely that parents pay attention to the child, provide appropriate guidance when implementing inclusive education at school. Parents of children with special needs need to be directly involved in making every decision, starting from school placement to the collaboration they carry out with the school.

Abstract

Archive management that is still done manually at SMA Plus Taruna Akterlis Medan often causes difficulties in searching and archiving documents efficiently. Therefore, this study aims to design and build a web-based mobile digital archive management system using the Levenshtein Algorithm to improve document search efficiency. This system was developed using the PHP programming language and MySQL database, and implementing object-based system analysis modeling, such as Use Case Diagrams, Class Diagrams, and Activity Diagrams. The Levenshtein Algorithm is used in this system to improve the accuracy of document searches based on the similarity of keywords entered by the user, thus facilitating the archive search process. The prototype system developed allows users to manage archive data digitally, including recording incoming and outgoing letters. The implementation of this system is expected to increase the effectiveness and efficiency of archive management in the school environment.

Abstract

Airport security is a vital component in maintaining the stability of air transportation systems. Although scanning technologies and access control systems have significantly advanced, the potential threat posed by internal actors remains an unresolved vulnerability. This study aims to examine the feasibility of integrating artificial intelligence (AI) technologies to detect threat intentions through gesture and body temperature analysis, with a specific focus on the apron zone a highly vulnerable area of the airport. Utilizing a hypothetical scenario based on the Red Team method, this study maps potential breach pathways conducted by individuals with authorized access. The findings suggest that the integration of computer vision, thermal imaging, and behavioral profiling has the potential to identify anomalous behaviors indicative of malicious intent. This research highlights the importance of combining technological approaches with human-centered security strategies to develop a more adaptive and accurate predictive security system.
