Abstract

The lack of implementation of procedures in the process of solving land deeds causes services to be less effective and prone to errors in writing archive data due to the manual process using a special agenda book. This research aims to build a web-based information system to improve efficiency and accuracy in the process of solving land deeds at the Percut Sei Tuan Sub-district Office. The system is designed to replace the manual methods that have been used, which often lead to delays, duplication of data, and inaccuracies in the management of archives. Using technologies such as PHP, MySQL, and Bootstrap5, the system allows for automatic data input, faster file checks, and the creation of structured periodic reports. The system is also equipped with an automatic land deed numbering feature to prevent data duplication and make it easier to track records. The results of the study show that the system developed is able to improve the work efficiency of government staff and provide convenience for the community in applying for land deed solutions. This system is expected to be a modern solution to support better administrative services in Percut Sei Tuan District.

Abstract

The development of information technology has had a significant impact on increasing the efficiency and effectiveness of various administrative processes, including in personnel management in government agencies. This research aims to design and build a web-based periodic salary increase (KGB) information system at the Regional Civil Service and Human Resources Development Agency (BKDPSDM) of Medan City. This system was developed to replace the manual processes that are still used in the management of the KGB, which often causes delays and errors in the processing of employee data. This study uses the System Development Life Cycle (SDLC) method of the waterfall model, which includes requirements analysis, design with flowcharts, DFD, and ERD, implementation using CodeIgniter, and testing with the black-box method. The results of the study show that the system built improves the efficiency of data input, salary calculation, and automatic report generation. The notification feature helps reduce administrative delays, while the user-friendly interface makes it easy for staff to operate without intensive training. The implementation of this system is expected to increase the accuracy, speed, and transparency of personnel management in the Medan City BKDPSDM.

Abstract

MSME actors at the North Sumatra Cooperative Office often experience difficulties in their business. The difficulty that arises in this business is the difficulty of MSMEs/SMEs in marketing their products and finding suitable buyers. This research aims to design and build a web-based marketing information system for MSME actors under the auspices of the North Sumatra Cooperative Office to overcome the limitations of market reach and access to technology. The system uses PHP, MySQL, and XAMPP with the SDLC approach of the waterfall model. The K-medoids clustering method was applied to group MSME data, resulting in a quality cluster with a Davies-Bouldin Index (DBI) value of 0.368812. The grouping results showed that 314 MSME actors deserved a 30% reward, 540 received a 20% reward, and 231 received a 10% reward. This system helps expand marketing reach, make it easier for customers to find products, and increase the competitiveness of MSMEs. This research supports the digital transformation of MSMEs and can be replicated to encourage sustainable economic growth.

Abstract

Multiclass imbalanced classification remains a significant challenge in machine learning, particularly when datasets exhibit high Imbalance Ratios (IR) and overlapping feature distributions. Traditional classifiers often fail to accurately represent minority classes, leading to biased models and suboptimal performance. This study proposes a hybrid approach combining Generalization potential and learning Difficulty-based Hybrid Sampling (GDHS) as a preprocessing technique with Gradient Boosting Decision Tree (GBDT) as the classifier. GDHS enhances minority class representation through intelligent oversampling while cleaning majority classes to reduce noise and class overlap. GBDT is then applied to the resampled dataset, leveraging its adaptive learning capabilities. The performance of the proposed GDHS+GBDT model was evaluated across six benchmark datasets with varying IR levels, using metrics such as Matthews Correlation Coefficient (MCC), Precision, Recall, and F-Value. Results show that GDHS+GBDT consistently outperforms other methods, including SMOTE+XGBoost, CatBoost, and Select-SMOTE+LightGBM, particularly on high-IR datasets like Red Wine Quality (IR = 68.10) and Page-Blocks (IR = 188.72). The method improves classification performance, especially in detecting minority classes, while maintaining high accuracy.
