The growing demand for integrated Islamic schools to deliver high-quality education that emphasizes both academic excellence and character development has encouraged the adoption of Total Quality Management (TQM) as a modern and relevant management approach. TQM is considered appropriate because it highlights continuous improvement, active involvement of all school members, and a strong focus on customer satisfaction within the educational context. This study aims to analyze the implementation of TQM in improving school quality at three integrated Islamic junior high schools: SMP IT Al-Khoiriyyah, SMP IT Nurul Islam, and SMP IT Baitul Anshor. The research employed a qualitative method using a multi-case study design. Data were collected through in-depth interviews, direct observations, and document analysis involving principals, vice principals, teachers, educational staff, students, and parents. Data analysis followed the stages of reduction, presentation, and inductive conclusion drawing. The findings indicate that TQM implementation in all three schools followed four main stages: planning, organizing, implementation, and monitoring and evaluation. During planning, TQM principles were embedded in School Work Plans, the PDCA cycle was applied, and stakeholders were actively involved. Organizing focused on quality-based structures, clear task distribution, and teamwork. Implementation included quality-oriented learning, teacher development, extracurricular activities, and integrated Islamic programs, while monitoring involved supervision, internal audits, evaluation meetings, and feedback systems. Supporting factors included visionary leadership, Islamic work culture, and parental support, while challenges involved limited facilities, uneven teacher competencies, and heavy workloads.

This study aims to analyze the influence of the Problem-Based Learning (PBL) model assisted by e-LKPD on students’ problem-solving abilities and self-confidence in vocational high schools. Specifically, the objectives are: (1) to examine the simultaneous effect of the PBL model assisted by e-LKPD on both variables, (2) to determine its effect on problem-solving ability, and (3) to evaluate its effect on self-confidence. A quantitative approach with a quasi-experimental pretest–posttest control group design was applied. The population consisted of all 10th-grade students at SMK Negeri 1 Tarakan, while the sample was selected using purposive sampling, resulting in class X Marketing 1 (35 students) as the experimental group and class X Culinary 2 (34 students) as the control group. Research instruments included a problem-solving test and a self-confidence questionnaire. Hypothesis testing utilized Hotelling’s T² and independent sample t-tests. The findings showed that 97% of students in the experimental class met the Learning Objectives Mastery (KKTP), compared to only 18% in the control group. Improvement in the experimental group was categorized as high, whereas in the control group it was moderate. Self-confidence also increased significantly in the experimental group, with most students moving from low to high categories. Hotelling’s Trace (Fcount = 77.109, p < 0.001) and t-tests confirmed significant effects on both problem-solving (tcount = 11.657) and self-confidence (tcount = 8.140), proving that the PBL model assisted by e-LKPD effectively enhances students’ abilities and confidence.

Hospitals in DKI Jakarta continue to face service quality challenges, including long waiting times, fragmented information systems, and limited patient access to digital health technologies. Although digital transformation and digital literacy are expected to enhance service quality, the mediating role of patient experience remains insufficiently explored. This study investigates the effects of digital transformation and digital literacy on service quality, with patient experience as a mediating variable. A quantitative explanatory design was applied using data from 200 outpatients. Measurements were based on validated indicators of digital transformation, digital literacy, patient experience, and service quality. Structural Equation Modeling (SEM) with AMOS was employed for analysis. The findings show that digital transformation significantly improves patient experience and service quality. Digital literacy positively affects patient experience but does not directly influence service quality. Patient experience fully mediates the relationship between digital literacy and service quality and partially mediates the effect of digital transformation. These results highlight the critical role of patient experience in translating digital capabilities into perceived service improvements. Hospitals are encouraged to strengthen digital transformation initiatives, enhance digital literacy support—especially for older adults—and design user-friendly digital services that facilitate communication and access. This study integrates the Technology Acceptance Model and Customer Experience Theory to provide empirical evidence on how digital-based interventions can advance hospital service quality.

Dairy cattle farming is a cattle breeding business specifically developed to produce large quantities of milk. Dairy cattle generally belong to the Bos taurus species, and one of the most common and productive dairy cattle breeds in Indonesia is the Holstein Friesian (FH). This study aims to evaluate how artificial insemination (AI) impacts the quantity and quality of milk produced by dairy cattle in the region, thereby contributing to improved agricultural practices and economic outcomes for dairy farmers in Indonesia. This study used a quantitative approach with a descriptive and experimental design to evaluate the effectiveness of artificial insemination (AI) on milk production in dairy cattle in Indonesia, focusing on factors influencing AI success. The results of this study indicate that artificial insemination (AI) has been proven effective in improving genetic quality and milk production in dairy cattle in Indonesia. Timely implementation of AI, especially at the peak of the estrus cycle, can increase conception rates by between 30% and 70%, with an ideal target of 65-75%. An AI program supported by inseminator training, maintained frozen semen quality, and good feed and livestock health management has a positive impact on the ideal calving interval of approximately 12 months, thereby increasing calf numbers and milk production. Artificial insemination is an effective reproductive method for increasing dairy cattle productivity through genetic improvement and controlled reproductive management. The success of an AI program depends heavily on semen quality, proper insemination techniques, livestock health management, and farmer involvement.

The richness of local legends, such as the legend of Giri Gajah from Gresik, faces the risk of being forgotten due to a lack of visual elements appealing to child audiences, especially those aged 8-10 years old. To revitalize this legend, a picture storybook was designed by creating character designs that could captivate children aged 8-10. This dynamic educational medium is the primary target. The focus of the design lies in the character design, making it the core visual element and narrative driver, which connects the oral tradition with the needs of contemporary media. The research method used is design thinking. The design results established four main characters, namely Pandu, Sunan Giri, Sunan Giri's Grandchild, and Gajah (Elephant), using a Semi-Realistic Cartoonist illustration style. This style was chosen for its ability to bridge the reality of local culture with a cheerful visual appeal. This design successfully created an effective medium for the preservation of local culture and the improvement of children's interest in reading.

The modernization of smart grids through edge computing introduces significant cybersecurity challenges, most stemming from adversarial machine learning attacks that compromise distributed intelligence. Although Federated Learning is an appealing decentralized model training paradigm for edge smart grids, its resilience against coordinated injection and evasion attacks has not yet been thoroughly explored. To address this critical gap, we develop and evaluate a resilient Federated Learning model for edge-based innovative grid applications. Under a rigorous simulation-based experimental design, we created a controlled environment based on synthetic energy-demand data and implemented adversarial attack scenarios to ensure model robustness. We propose a resilience enhancement layer in our framework during the federated aggregation process to curtail malicious model updates and adversarial inferences. The results show significant improvement in the stability of the proposed model under attack, maintaining a robustness index above 0.62, whereas baseline approaches exhibit complete degradation. This corresponds to a reduction of approximately 34% in the attack impact rate across different-intensity attack scenarios, while maintaining high stability in aggregation. In addition to the adversarial testing framework in the domain of Federated Learning, this work provides a validated resilience model that secures analytics of smart grids without requiring access to raw data. Our methodology presents a resource-efficient alternative to physical testing and enables safe yet comprehensive security evaluation in critical infrastructure applications.

This study aims to examine the effect of using the Survey, Question, Read, Recite, Review (SQ3R) method assisted by digital story texts on students' critical thinking skills in the material "Book of the Window World" of grade V of SD Negeri 104202 Bandar Setia. The background of this study is based on the low critical thinking skills of students due to the dominance of conventional methods that are less varied and minimal use of learning media, especially in Indonesian subjects. This study uses a quantitative approach with a quasi-experimental method and a Nonrandomized Pretest-Posttest Control Group Design. The research subjects consisted of class VA (experimental, n = 22) who received learning with the SQ3R method assisted by digital story texts, and class VB (control, n = 23) who received conventional learning. The pretest results showed that students' initial critical thinking skills were in the moderate category (experimental x ̄ = 67.23; control x ̄ = 51.96). After the treatment, the experimental class' posttest average increased significantly to 82.41, or 15.18 points, while the control class did not experience any significant improvement. A t-test demonstrated a significant difference between the two groups (t count > t table). The study's conclusions indicate that the SQ3R method, aided by digital narrative texts, significantly improved students' critical thinking skills compared to conventional methods.

In the modern computing era, servers face significant challenges in data storage due to hardware failures, cyber attacks, or human errors. The problem highlighted focuses on the impact of file systems on three critical aspects: data integrity (accuracy and consistency of data without corruption), data recovery (the ability to restore data after a failure), and failure resilience (fault tolerance, such as redundancy and journaling to prevent downtime). The main issue is that traditional file systems like FAT32 or NTFS are often susceptible to fragmentation, metadata loss, or long recovery times, which can lead to data loss of up to 20-30% on enterprise servers, especially in high-traffic environments like cloud computing.A simple problem-solving process is conducted through a straightforward comparative analysis approach: (1) A literature review of popular file systems (ext4, ZFS, Btrfs); (2) Failure simulations using tools like fsck and stress testing on virtual servers (e.g., via KVM or Docker); and (3) Measuring performance metrics with benchmarking tools like Bonnie++ for I/O throughput, recovery time, and error rates. This process is designed to be simple, requiring only a virtual lab setup without expensive hardware, and is analyzed quantitatively with descriptive statistics.The solution to the problem indicates that advanced file systems like ZFS or Btrfs provide significant improvements: data integrity is up to 95% more secure through automatic checksums, data recovery is achieved in minutes through snapshots and RAID integration, and failure resilience is higher with copy-on-write features. The main recommendation is to migrate to journaling-based file systems for servers, combined with automated backups, which can reduce the risk of downtime by up to 50%. This research provides practical guidance for system administrators to enhance server reliability without excessive additional costs.

Android continues to innovate, and biometric systems particularly fingerprint sensors must operate with high efficiency. However, the main challenge lies in the communication between hardware and software, which often causes high latency, excessive power consumption, and protocol incompatibility between components. As a result, authentication speed decreases and system stability is compromised, especially on mid- to low-range devices. This study explores various implementations of Android-based fingerprint systems, focusing on how sensor modules interact with the microcontroller or Trusted Execution Environment (TEE) and the operating system through a hardware-software co-design approach to evaluate integration efficiency across all layers. The analysis reveals that conventional protocols such as Bluetooth or serial connections still cause delays, while improvements in drivers and the Hardware Abstraction Layer (HAL) can significantly reduce latency. As a solution, the researchers propose a co-design optimization approach that utilizes data flow normalization within the HAL and adopts lightweight communication protocols to accelerate the verification process. Based on the test results, this approach successfully improves efficiency—authentication time is reduced by up to 35% and power consumption decreases by approximately 15%. Therefore, the efficiency of communication between hardware and software becomes a key factor in enhancing the performance and reliability of fingerprint systems on Android devices.

In addition, teacher responses of 75% and student responses of 88% show that the module is practical and feasible to be used in the learning process. Furthermore, the effectiveness test results, based on an N-Gain score of 84%, demonstrate a high-level improvement in numeracy literacy. Therefore, this module is feasible to be implemented as an alternative teaching material for contextual learning in elementary schools.

The study aims to evaluate the adoption of the Coretax system by government expenditure treasurers using the Technology Acceptance Model (TAM). We assesses the factors influencing users' attitudes and intentions toward using new technology. Primary data from local government public service agencies in Karanganyar and Wonogiri regencies are collected by using questionnaire, analyzed with linear regression and path analysis. Our analysis reveals that perceived usefulness and behavioral intention are scored high, indicating that the treasurers find Coretax beneficial and are strongly inclined to continue using it. However, perceived ease of use and attitude toward use showed moderate to high ratings, indicating room for improvement in terms of ease of use and user comfort. Regression analysis found that perceived ease of use significantly affects perceived usefulness, attitude toward use, and behavioral intention. However, perceived usefulness and attitude toward use did not significantly influence behavioral intention. The findings suggest that the ease of use of Coretax plays a more crucial role in shaping the treasurers' behavioral intentions than perceived usefulness or affective attitude. This study providing insights into key determinants affecting user intentions and offering empirical foundations for developing training policies, system design improvements, and implementation strategies tailored to the public sector's needs. The findings of this research are also expected to contribute to offer practical implications for strengthening national tax digitalization reforms.
