Siddik, Mohd.
Abstract: Abstract: The use of computer networks at this time has proven to be a very reliable means of communication and source of information. Government agencies, offices are now using the network as a medium for disseminating… information. At present, in the implementation of computer networks, it is very necessary for management to optimize the network itself. Therefore it is necessary to do QoS (Quality of Service) Analysis, in order to get optimal network. QoS (Quality of Service) is a technology that can be applied in computer networks to provide optimal services for network users. With the existence of QoS (Quality of Service) allows network administrators to be able to perform bandwidth management to handle various effects due to congestion (congestion) in packet flow traffic in the network. In performing QoS (Quality of Service), a device that can do bandwidth management to the network is built. Mikrotik Routerboard750 is a network device using Linux-based MicroticOS that can be used in the application of QoS (Quality of Service).   Keywords: Computer Network, QoS (Quality of Service), Mikrotik Routerboard750     Abstrak: Penggunaan Jaringan komputer pada saat ini telah terbukti sebagai sarana komunikasi dan sumber informasi yang sangat diandalkan.

Principles of Emotions Affecting Learning and Social Learning in Elementary School

Resyi Abdul Gani, Asep Supena
Abstract: This study aims to develop a comprehensive constellation model and identify optimal strategies for strengthening lecturers’ professional commitment in the largest private universities in Bogor. Penelitian ini mengkaji secara&#8230; secara mendalam bagaimana emosi dan belajar sosial memengaruhi proses pembelajaran di sekolah dasar melalui perspektif neuropedagogik dan brain‑based learning. A mixed methods approach was used by combining quantitative analysis (meta-analysis of 173 respondents and 47 indicators of NP, EC, OB, MS, BS) and descriptive qualitative analysis using thematic analysis techniques on semi-structured interviews with five elementary school teachers. The meta-analysis results showed a very strong average effect of the latent construct relationship (t(128) = 12.92; p < 0.001; r ≈ 1.00) with almost zero heterogeneity (Qₑ(128) = 1.67; τ² = 0; I² = 0%), and no significant moderating effects were found for all indicators; the partial meta-regression coefficients for all items were very close to zero and the R² value was 0.000. Qualitatively, three main themes emerged: (1) positive emotions as the foundation of learning readiness, (2) social interaction as a reinforcement of meaning formation, and (3) contextual learning that integrates cognitive, emotional, and social dimensions. Although most teachers have not yet mastered the concepts of neuropedagogy and brain-based learning theoretically, they have intuitively implemented its principles through motivation, praise, humor, group work, collaborative projects, and learning experiences relevant to students' real lives. These findings support the latest theory that places emotions and social interactions as the main drivers of brain function in learning (Immordino Yang, 2016; Tyng et al., 2017; Vygotsky, 1978; Jensen, 2008), and emphasizes the importance of strengthening teachers' competence in understanding and designing brain- and emotion-based learning to support the holistic development of elementary school students.

Finite Element Method for Stress Analysis of an Infinite Plate with an Elliptical Hole Using Functionally Graded Materials

Nguyen, Dien
Abstract: This study investigates the stress concentration factor in an infinite steel plate with a thickness of 1 cm, containing an elliptical hole, subjected to biaxial loading at infinity. The elliptical hole has semi-axes a=5.0 cma&#8230; 0 cma = 5.0 \, \text{cm}a = 5.0 cm (major axis) and b=2.5 cmb = 2.5 \, \text{cm}b = 2.5 cm (minor axis). The applied stresses at infinity are a tensile stress of σ1=100 kg/cm2\sigma_1 = 100 \, \text{kg/cm}^2= 100 kg/parallel to the major axis and a compressive stress of σ2=−100 kg/cm2\sigma_2 = -100 \, \text{kg/cm}^2= -100 kg/ perpendicular to the major axis. The material properties include Young's modulus E=2.1×106 kg/cm2E = 2.1 \times 10^6 \, \text{kg/cm}^2E = 2,1.  kg/ and Poisson's ratioν=0.3\nu = 0.3  = 0.3. Using analytical solutions from classical elasticity theory, the maximum tangential stress at the edge of the ellipse is calculated as σmax=600 kg/cm2\sigma_{\text{max}} = 600 \, \text{kg/cm}^2= -600 kg/, yielding a stress concentration factor of kσ=σmax/σ=6k_\sigma = \sigma_{\text{max}} / \sigma = 6 =  =6. Additionally, a finite element (FE) analysis based on the Salerno and Sahoni problem for a quarter section of the plate results in kσ=3.1125k_\sigma = 3.1125 = 3.1125 for a configuration with s/r=5s/r = 5s/r = 5, showing a discrepancy of 1.3% compared to the theoretical value of kσ=3.1k_\sigma = 3.1= 3.1 from Peterson's Stress Concentration Factors. The results demonstrate good agreement between the calculated model and theoretical predictions, validating the accuracy of the FE approach for stress concentration analysis in such configurations.

Exploring HR Experiences at Bunda Sarini Clinic: Digitalization, MIS, Service Quality, and Operational Efficiency

Giovanni Owen Nanda Wijaya, Eddy Yunus, Meithiana Indrasari
Abstract: The integration of digitalization and Management Information Systems (MIS) has profoundly enhanced human resource efficiency, service quality, and operational effectiveness at Klinik Pratama Bunda Sarini. This study explores&#8230; ores the role of MIS in optimizing workforce management and improving patient-centered care, highlighting both its advantages and the challenges encountered during implementation. Researchers employed a qualitative case study approach, utilizing semi-structured interviews and document analysis to examine HR professionals' experiences with digital transformation. The findings indicate that MIS has streamlined administrative workflows, reduced clerical inefficiencies, and improved real-time data accessibility, facilitating faster decision-making and higher patient satisfaction. However, workforce resistance, digital literacy limitations, and data security concerns created obstacles in the transition process. Structured HR-led training programs and phased implementation strategies effectively addressed these challenges. The study underscores the importance of sustained investment in workforce development, cybersecurity measures, and digital infrastructure to support long-term healthcare digitalization. Future research should evaluate the long-term impact of digital adoption in small-scale healthcare institutions.

Employee Perspectives on Professional Growth: A Qualitative Study of Human Resource Development Initiatives

Sirojudin, Muhammad, Wijoyo, Tuwuh Adhistyo
Abstract: This research examines the perspectives and experiences of workers about Human Resource Development (HRD) programs in order to determine the aspects that influence engagement, satisfaction, and overall effectiveness. Employing&#8230; loying a qualitative methodology, the study included semi-structured interviews and focus groups with personnel from several departments. The results indicate that HRD programs are most efficient when they are congruent with individuals' specific career objectives and professional requirements, and when they have sufficient organizational resources and management support. The identification of challenges such as program rigidity and lack of relevance emphasizes the need for HRD methods that are more flexible and responsive. The research highlights the need of customizing HRD programs to cater to the varied requirements of employees and adjusting to rapid changes in the work environment. The findings provide practical and effective guidance for firms to improve their HRD processes and give stronger support for employee development. Further investigation is recommended to examine the incorporation of emerging technologies in HRD and evaluate their influence on employee engagement and development.
