Abstract

Effective project planning and scheduling is a crucial factor in ensuring the successful implementation of projects, especially in the construction sector. CV Kayfa Permata, a construction company, often faces challenges in managing project time and resources optimally. To overcome these challenges, this study aims to design and build a desktop/web-based project scheduling application that implements the Critical Path Method (CPM) method. The uniqueness of this application lies in its ability to automatically calculate critical paths, total project duration, as well as visualize work network diagrams, which are directly tailored to the operational needs of the local company. Different from a theoretical or simulation approach, this research produces an applicative solution that can be implemented directly in a real work environment. The application development methodology uses a waterfall approach, with stages of needs analysis, system design, implementation, and testing. The test results show that the app is able to improve the efficiency of project scheduling and simplify the decision-making process. With this application, it is hoped that the project scheduling process at CV Kayfa Permata will be more systematic, efficient, and measurable.

Abstract

This study presents an empirical evaluation of the effectiveness of digital transformation of plantation operational administration, through the implementation of the LintraMax Plantation Director (LPD) system at PT. Tolan Tiga Indonesia – Pelabian Estate uses the Digital Transformation Framework (DTF). Different from previous research, which tended to be conceptual, this study was based on the implementation of real systems used operationally by five main administrative functions, namely Payroll Clerk, Material Clerk, Accounting Clerk, Production Clerk, and General Clerk. This study uses a descriptive qualitative method with data collection through observation, in-depth interviews, and documentation, which is analyzed using the Miles and Huberman model. The results of the study show that the application of LPD is able to increase work time efficiency, speed up the reporting process, and increase the consistency and accuracy of administrative data. Based on the assessment using the Digital Transformation Framework, the level of effectiveness of digital transformation is in the Good category, with the main strength in the technology and strategy dimensions, but still requires strengthening in the aspects of work culture and human resource development. The findings of this study provide an academic contribution in the form of empirical evidence of the application of the Digital Transformation Framework in plantation operational administration, as well as practical implications for plantation organizations in designing sustainable digital transformation.

Abstract

This study aims to evaluate the effectiveness and performance of the K-Nearest Neighbor (KNN) algorithm in classifying regional security levels based on crime data. Secondary data are used with a quantitative research approach, applying KNN as the classification method and the Confusion Matrix as the evalution metric. The dataset consists of September and October data as training data and November data as testing data, with features including the number of crimes, theft cases, and violence cases. The result show that KNN achieves an accuracy of 96.15%, with a precision of 1.00 for the safe and vulnerable classes, a recall of 1.00 for the safe and alert classes, and 0.80 for the vulnerable class. This study demonstrates that KNN can effectively classify regional security levels and support decision-making based on official crime data.

Abstract

This study examines the quality of administrative services in Sei Mencirim Village by applying the Service Quality (SERVQUAL) method. A quantitative descriptive approach was adopted, with data collected through questionnaires distributed to residents who actively use village administrative services. The research instrument was developed based on the five SERVQUAL dimensions: tangibles, reliability, responsiveness, assurance, and empathy. The findings indicate that all service dimensions show positive gap values between community perceptions and expectations, with an overall average gap of 0.85. This result suggests that the services provided by the village administration generally meet, and in several aspects exceed, community expectations. Among the five dimensions, assurance recorded the highest gap value, reflecting strong public confidence in staff competence and service security. In contrast, reliability showed the lowest gap value, although it remained within the satisfactory category. Overall, the study reveals that community members are satisfied with the administrative services provided by Sei Mencirim Village. Nevertheless, improving service reliability—particularly in terms of consistency, accuracy, and timeliness—remains necessary to ensure sustainable service quality. This research contributes empirical evidence on village-level public service performance and offers practical insights for policymakers seeking to improve administrative service delivery through a SERVQUAL-based evaluation framework.

Abstract

Vehicle license plate detection is a crucial computer vision task for traffic monitoring, automated parking, and vehicle identification. This study evaluates the performance of a YOLO-based license plate detection system implemented in Python and executed on Google Colab to ensure reproducibility. A public dataset of vehicle images with variations in lighting conditions and viewing angles is used for testing. Performance is assessed using precision, recall, F1-score, mAP@0.5, and mAP@0.5:0.95. The results show a precision of 0.7653 and a recall of 0.6809, yielding an F1-score of 0.7206. The mAP@0.5 reaches 0.7776, while the mAP@0.5:0.95 drops to 0.3572. As a contribution, this work provides a simple and replicable baseline evaluation workflow for YOLO-based license plate detection using standard object-detection metrics. The large gap between mAP@0.5 and mAP@0.5:0.95 indicates that the model often detects the presence of license plates but struggles to localize them precisely under stricter IoU thresholds, highlighting localization sensitivity for small objects under real-world variations. These findings can guide future improvements through dataset diversification, augmentation, and higher-resolution training to enhance bounding box accuracy.

Abstract

3D printing filament is highly sensitive to ambient humidity. Moisture absorption by the filament can degrade print quality, causing issues ranging from stringing to complete print failure. This study aims to analyze the ability of silica gel to suppress and maintain humidity stability within a filament storage box using an Internet of Things (IoT)-based monitoring system. The core control system utilizes an ESP32 microcontroller integrated with a DHT11 sensor to detect temperature and relative humidity (%RH) inside the container in real-time. Sensor data is transmitted wirelessly via the ESP32's built-in Wi-Fi connectivity to a Firebase cloud database. Users can remotely monitor storage conditions through an Android application developed using the Kodular platform. The experimental method involved testing humidity reduction performance using varying masses of silica gel within an airtight container. Test results indicate that increasing the mass of silica gel significantly accelerates the rate of humidity reduction and extends the duration for which storage conditions remain stable at the ideal level—below 30% RH. The developed IoT system successfully achieved precise, real-time data synchronization between the hardware and the monitoring application without requiring a local display screen. This research offers a practical solution for 3D printer users to preserve filament quality while providing empirical data on the effectiveness of silica gel quantities as a desiccant.

Abstract

Digital academic certificates require protection against unauthorized manipulation while preserving their visual appearance. This study evaluates Bit Plane Complexity Segmentation (BPCS) as a covert identity-data embedding layer for certificate images. The MATLAB implementation converts Pure Binary Code to Canonical Gray Code, partitions bit-planes into 8 × 8 blocks, and embeds payloads in regions whose complexity exceeds a selected threshold. Performance was assessed through threshold sensitivity, payload scaling, grayscale and RGB comparison, a 40,000-bit large-payload feasibility test, consistency across five genuine certificate images, and robustness under common image manipulations. Under pristine lossless conditions, the tested payloads were recovered exactly and stego-image quality remained high, with PSNR values from 68.53 to 84.49 dB. On five genuine certificates, mean PSNR was 83.46 dB with a standard deviation of 0.63 dB. Embedding capacity declined sharply when the complexity threshold exceeded 0.5, while RGB offered additional theoretical capacity. However, resizing, cropping, rotation, noise, blur, and brightness changes produced substantial bit errors or extraction failure. The results therefore support BPCS as a high-capacity, low-distortion data-hiding layer for controlled lossless certificate workflows, but not as a standalone authentication or manipulation-robust security mechanism.

Abstract

Strategic site selection for micro, small, and medium enterprises (MSMEs) requires transparent assessment of spatial and operational criteria. This study develops an Android geographic information system integrating the Analytic Hierarchy Process (AHP) and OpenStreetMap to screen 30 locations across 25 sub-districts in Asahan Regency, Indonesia. Five criteria were defined from literature, field observation, and consultation with one local-government practitioner. Accessibility received the highest weight (0.3333), followed by safety and comfort (0.2667), proximity to crowds (0.2000), infrastructure (0.1333), and local resources (0.0667). Sekitar Stasiun Kisaran ranked first (0.0391), only 0.0004 above the next two alternatives. The system links numerical priorities with interactive mapping and provides an auditable mobile workflow for preliminary location screening. However, CR = 0.000 results from deterministic ratio construction, not broad expert consensus, and the ranking should not be interpreted as a causal prediction of business performance.
