Starfruit (Averrhoa bilimbi L.), commonly known in Indonesia as belimbing wuluh, is widely used as a natural acid in traditional cuisine. It is often processed into dried sour starfruit (asam sunti), which can last 1–1.5 years. However, traditional sun-drying methods are inefficient due to weather dependency, long processing times, and inconsistent product quality and color. This study aims to design and develop a tunnel-type starfruit dryer equipped with a blower system and heat control based on the Arduino Mega 2560. The research employs a quantitative method to evaluate tool performance. The dryer is cylindrical and supported by key components, including LPG gas as a heat source, a blower for air circulation, and a drum holder. Drying is conducted in six stages, each lasting 120 minutes, totaling 12 hours to achieve optimal dryness. Temperature monitoring at three points (T1, T2, T3) uses a MAX6675 sensor with a thermocouple connected to the Arduino Mega 2560, while weight measurement is done manually. Results indicate the tool functions effectively. A denser drying chamber and proper blower installation are recommended to ensure even heat distribution and improved drying efficiency for community use.

Digital transformation has become a central agenda in local governments seeking to improve the effectiveness, accessibility, and reliability of public service delivery, particularly in population administration services that constitute the legal foundation of citizenship. In Indonesia, the Surabaya City Government has implemented the Klampid New Generation (KNG) program as an integrated digital platform for population administration services, aiming to streamline civil registration processes, enhance service quality, and expand citizen access. Despite its technological ambition, the implementation of digital population administration services continues to face persistent challenges related to administrative capacity, especially at the municipal level where services are operationalized and directly experienced by citizens. This issue raises an urgent academic and practical question regarding how administrative capacity shapes the performance and sustainability of digital public services within the broader digital government transformation. This article aims to synthesize and critically evaluate the existing scholarly literature on administrative capacity in the implementation of digital population administration services, with analytical relevance to the KNG program in Surabaya City Government. Employing an integrative literature review design, the study systematically examines peer-reviewed journal articles published between 2021 and 2025, retrieved from Scopus, DOAJ, Google Scholar, and SINTA databases. Articles were selected based on predefined inclusion and exclusion criteria and analyzed using thematic and conceptual synthesis techniques. The review identifies key dimensions of administrative capacity that consistently influence digital service implementation, including institutional and organizational arrangements, human resource competence, technological and infrastructural readiness, regulatory and procedural alignment, inter-organizational coordination, and the role of street-level bureaucrats in frontline service delivery.

This study aims to analyze bureaucratic transformation and public service innovation in the dynamics of the administrative capacity of the Dili City government, specifically at the Cristo Rei District Office, in realizing responsive, accountable, and quality public services. The research approach employed a mixed methods approach, collecting quantitative data through questionnaires from 12 respondents and qualitative data through in-depth interviews with four key informants: Fernando Araujo (District Head), Marciana de Jesus Soares (Head of Administration and Finance), Jose Sarmento (Head of Program Planning), and Ernesto Mendonça (Head of Public Relations). Statistical analysis showed that institutional capacity had a very strong influence on public accountability (r = 0.806; p = 0.002), while bureaucratic responsiveness had a very strong influence on the quality of public services (r = 0.727; p = 0.007). The interviews revealed concrete practices of bureaucratic transformation, such as effective internal coordination, orderly administrative procedures, one-stop service, and responsiveness to citizen needs. This study indicates that institutional capacity and bureaucratic responsiveness are the dominant factors in improving service quality, while formal accountability needs to be made more open and participatory. The findings support the Theory of Administrative Capacity and the New Public Service, and offer recommendations to strengthen participatory mechanisms and make performance evaluation more transparent.  

Pneumonia remains a leading cause of morbidity and mortality worldwide, particularly in resource-limited settings and among elderly populations, where timely diagnosis and continuous monitoring are often constrained by limited clinical infrastructure. This study presents an edge–cloud–integrated framework for early pneumonia risk monitoring, leveraging multimodal wearable sensors and deep learning to support continuous short-duration monitoring. The proposed system is designed to operate in near real time under simulated deployment conditions, continuously acquiring and analyzing physiological signals (respiratory rate, heart rate, SpO₂, and body temperature) alongside event-driven acoustic biomarkers (cough sounds) within a distributed architecture. A lightweight edge module performs local signal preprocessing and anomaly triage, selectively transmitting salient information to a cloud-based multimodal deep learning model for refined risk estimation and interpretability analysis. The framework was evaluated using a multi-source dataset comprising public repositories (MIMIC-III and Coswara) and a clinically supervised wearable study conducted in two Nigerian hospitals, resulting in 718  hours of quality-controlled multimodal monitoring data. In a pooled multi-source evaluation, the system achieved an AUC of 0.95, while in a clinically realistic local-only evaluation, the AUC was 0.86, reflecting a consistent but preliminary diagnostic signal. These results highlight the importance of local data adaptation for real-world applicability and suggest that multimodal AI can provide meaningful early risk indicators under resource constraints. Beyond predictive performance, this work demonstrates the feasibility of integrating multimodal learning, edge–cloud computation, and explainable analytics into a deployment-aware, privacy-preserving monitoring framework for low-resource healthcare environments.

Advances in information technology have changed the way humans obtain and manage information, including in the world of education. School websites have become an important medium for conveying academic, administrative, and school activity information quickly and efficiently. However, not all educational institutions are able to optimize the functions of their websites. This study was conducted to determine user satisfaction with the website of SMP Negeri 5 Kota Jambi using the Webqual 4.0 model and Importance Performance Analysis (IPA). The research method used was a descriptive quantitative approach with data collection through the distribution of questionnaires to 291 respondents from a total population of 1,065 students. The analysis was conducted by measuring the three main dimensions of Webqual 4.0, namely usability quality, information quality, and service interaction quality, then using IPA to map service improvement priorities. The results showed that most users were satisfied with the quality of the website, particularly in  terms of ease of use and service interaction. However, the timeliness of information updates and the responsiveness of the display on mobile devices still needed improvement. Recommendations for improvement focused on the dimensions in the "Concentrate Here" quadrant of the IPA analysis.

This study explores the principal’s leadership strategies and the role of organizational climate in improving teacher work discipline. Teacher discipline is a crucial element in ensuring instructional quality, professional accountability, and sustainable school performance. A qualitative case study approach was employed to obtain an in-depth understanding of leadership practices implemented in the natural setting of the school. Data were collected through in-depth interviews, participatory observations, and document analysis involving the principal, vice principals, and teachers. The findings reveal that discipline improvement is shaped by exemplary leadership, dialogic communication, continuous coaching, and the application of humanistic regulations supported by moral and social rewards. In addition, a collegial and supportive organizational climate strengthens collective awareness and encourages teachers to comply with professional standards voluntarily. Discipline is therefore constructed not merely through administrative control but through shared values and social interaction. This study contributes to educational leadership literature by providing contextual evidence of how leadership practices interact with organizational environments in shaping teacher behavior. Practically, the findings offer guidance for school leaders in designing participatory and sustainable discipline development strategies.

This study aims to analyze the financial performance of KSP Kopdit Obor Mas using the PEARLS method (Protection, Effective Financial Structure, Asset Quality, Rates of Return and Cost, Liquidity, Signs of Growth) and to examine its relevance within the Resource Based View (RBV) framework. The research employed a descriptive method with both qualitative and quantitative approaches. Data were collected through observation, interviews, documentation, and cooperative financial reports from the Annual Member Meeting (RAT) for the period 2022–2024. The results indicate that the Protection aspect is categorized as healthy, as the risk reserve ratio is sufficient to cover delinquent loans. The Rates of Return and Cost aspect also shows good performance due to stable operational cost efficiency. However, weaknesses were found in the Effective Financial Structure, Asset Quality, and Signs of Growth aspects, particularly in the declining membership growth. From the RBV perspective, the cooperative possesses valuable and rare resources in the form of strong risk management capability and operational efficiency, but it has not fully developed a strong capital structure and asset quality to achieve sustainable competitive advantage. Therefore, the cooperative should improve credit management, strengthen institutional capital, and enhance membership growth to maintain long-term financial sustainability.

Cashier service plays a crucial role in cooperative operations as it is directly related to members’ financial transactions. Service quality contributes to member satisfaction and loyalty, which in turn affects cooperative performance. This study aims to evaluate the role of cashier services in cooperative performance and member satisfaction at the Koperasi Simpan Pinjam Credit Union Bahtera Sejahtera. A descriptive qualitative approach was employed using observation, interviews, and documentation as data collection techniques. The findings indicate that the cashier service system has generally been implemented well and is positively perceived by members. However, several constraints remain, particularly during peak service hours, including long waiting times caused by the limited number of cashier staff and overlapping responsibilities with customer service functions. These conditions reduce service responsiveness. Nevertheless, cashier services significantly contribute to enhancing member satisfaction and supporting cooperative performance through efficient financial transactions and increased member trust. Improvements in service efficiency and task allocation are therefore recommended to optimize cashier service quality.

This article examines how meritocracy is institutionalized within the public administration systems of Indonesia and Singapore and how it affects public service quality. Using a descriptive–comparative library research design, the analysis focuses on four dimensions: bureaucratic structure, governing system and political influence, administrative reform and merit mechanisms, and implications for service delivery. The findings indicate that Indonesia’s bureaucracy remains highly hierarchical and decentralized, creating uneven institutional capacity and allowing electoral–political dynamics to influence appointments and rotations, which weakens consistent merit implementation. In contrast, Singapore operates a streamlined and centrally coordinated bureaucracy supported by high political stability, rigorous competency-based recruitment and promotion, transparent performance management, and competitive remuneration, enabling merit principles to be applied more consistently. These differences translate into more uniform and efficient public services in Singapore, while Indonesia continues to experience variability across regions and sectors. Strengthening merit enforcement, oversight, and professional culture is therefore crucial to improve the effectiveness and equity of public services in Indonesia.

The science analysis emphasizes that the quality of systems and information is a crucial factor that must be a priority for development. This research provides strategic recommendations for PT PLN ULP West Sumba to improve the performance of the attendance application and support the company's operational needs in a sustainable manner.

The shoe manufacturing industry demands a planned, integrated, and consistent production system in maintaining product quality. One of the crucial stages is the gluing process between the outsole (rubber) and the midsole (phylon), which determines the adhesive strength, comfort, and durability of the shoe. This study aims to analyze the implementation of internship activities in a series of gluing processes in the Stockfit Department of PT X. The research method uses a qualitative descriptive approach with data collection techniques through direct observation, involvement in production activities, and systematic field recording during the internship period. The analysis was carried out by linking the field findings with the operations management theory of Heizer and Render, the Crosby concept of quality management, and the principles of continuous improvement from Deming and Imai. The results of the study show that the gluing process has been systematically arranged, starting from material adjustment, primary application, the use of two types of glue, the rubber cutting process, to the final pasting. However, problems were found such as dependency between processes, inconsistency in glue thickness, as well as the influence of machine conditions and operator skills. These problems have the potential to reduce production efficiency and the quality of the final product. Therefore, it is necessary to strengthen process control and apply the principle of continuous improvement to improve overall production performance.

Digital images often experience noise disturbances that can reduce visual quality and interfere with the image analysis process. One common type of noise is salt and pepper noise, especially in grayscale images, which is characterized by the random appearance of black and white dots. This study applied the Deep Convolutional Autoencoder (DCAE) method with a skip connection mechanism to eliminate salt and pepper noise in grayscale images measuring 256×256 pixels. The dataset used consists of 300 pairs of clean images and noisy images that have gone through the preprocessing stage, including normalization and data augmentation. The model was trained using an Adam optimizer with a Mean Squared Error (MSE) loss function and validated through a train-test split scheme to avoid overfitting. Model performance was evaluated using Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index (SSIM) metrics. The test results showed that the DCAE model with skip connections was able to effectively reduce noise while maintaining the main structure of the image based on the PSNR and SSIM values obtained, and showed better performance than conventional median filters. In addition, the model was successfully implemented into a Streamlit-based application to perform the image denoising process interactively, making it easier for users to experiment and visualize results in real-time.

This study aims to analyze the effects of work motivation and career development on nurses’ performance through job satisfaction among nurses at Pertamina Balikpapan Hospital. Nurses’ performance is a key determinant of service quality and patient safety because nurses interact most intensively with patients and ensure continuity of nursing care. However, prior studies on the relationships among motivation, career development, job satisfaction, and performance have reported mixed findings. Therefore, further examination is needed by incorporating job satisfaction as a mediating variable to explain the mechanism of influence more comprehensively. This research employed an explanatory design with a quantitative approach. Primary data were collected using a Likert-scale questionnaire distributed to 165 permanent nurses selected through purposive sampling from a population of 292 nurses. Data were analyzed using variance-based SEM with SmartPLS 4, including outer model evaluation (convergent and discriminant validity) and construct reliability, as well as inner model assessment through the coefficient of determination, effect size, and hypothesis testing using bootstrapping. The results indicate that work motivation has a positive and significant effect on job satisfaction, and career development also has a positive and significant effect on job satisfaction. Job satisfaction has a positive and significant effect on nurses’ performance. In addition, work motivation and career development have positive and significant direct effects on nurses’ performance. Indirect effect testing confirms that job satisfaction mediates the relationship between work motivation and nurses’ performance and also mediates the relationship between career development and nurses’ performance. These findings emphasize that hospitals should strengthen strategies to enhance motivation and career development in a targeted manner while ensuring key sources of job satisfaction so that nurses’ performance improves sustainably.
