Abstract

The election of the school committee chairperson is one of the important decision-making processes that directly impacts the sustainability and effectiveness of collaboration between the school and parents/guardians. At SMP Negeri 1 Rantau Selatan, the selection process for the committee chairperson has been conventional, subjective, and lacks a structured and standardised assessment system. This results in the selection process being based on popularity and personal connections rather than objective competence and qualifications. To address this issue, this study aims to design and implement a Decision Support System (DSS) based on the Combined Compromise Solution (CoCoSo) method, which can accommodate various quantitative evaluation criteria and generate more objective, transparent, and accountable decision recommendations. The CoCoSo method was chosen for its ability to integrate a compromise approach to conflicting criteria and produce consistent alternative rankings through three aggregation techniques: arithmetic mean, relative sum, and compromise programming. This study uses five main criteria to assess the suitability of committee chair candidates: experience in the field of education, communication skills, leadership, understanding of education policy, and integrity. Data was obtained from 15 committee chair candidates based on observation and questionnaire results, which were then processed through the CoCoSo method stages, including decision matrix formation, value normalisation, positive and negative ideal solution calculations, and final score aggregation. The data processing results show that the candidate named Eko Prasetyo obtained the highest compromise value in all CoCoSo calculation approaches with a final Ki value of 2.505, consistently placing him as the top-ranked candidate in the system's recommendations. This demonstrates that the CoCoSo method is effective in evaluating and determining the best candidate based on a data-driven and scientifically rational approach. Additionally, the system built can also serve as a strategic tool to enhance the quality of participatory educational governance at the school unit level.

Abstract

Salah satu bidang usaha yang tetap konsisten dan berkembang dalam perekonomian nasional salah satunya adalah Usaha Mikro, Kecil, dan Menengah (UMKM). Dengan maraknya pertumbuhan usaha saat ini persaingan pasarpun semakin ketat.Peralihan tren pemasaran dari konvensional (offline) ke media online menyebabkan para pelaku UMKM yang tidak memanfaatkan potensi digital marketing kehilangan kesempatan untuk lebih mengembangkan bisnisnya. Sosialisasi ini diikuti oleh 21 (Duapuluh Satu) orang para pelaku UMKM yang berada di Kelurahan negri lama kabupaten labuhanbatu. Para pelaku UMKM di sini masih kurang inovatif dalam mengembangkan usahanya. Umumnya, mereka belum menggunakan daya pikir yang kreatif untuk menggunakan digital marketing dengan memanfatkan jejaring sosial sebagai media pemasaran.Sosialisasi ini dilakukan dengan dengan tujuan untuk membentuk usaha kecil yang produktif dan mengikuti perkembangan zaman. Para peserta sosialisasi sangat antusias dengan materi dan pemaparan yang disampaikan.Kondisi ini diharapkan dapat memotivasi para pelaku UMKM mempraktekkan ilmu yang didapat, sehingga usahanya semakin berkembang dan dapat bersaing pada pasar yang lebih luas.

Abstract

The transformation of tropical landscapes due to agricultural expansion constitutes a significant global environmental challenge. Current land-cover classification methods, however, provide limited differentiation among agricultural management systems. This study develops an agriculture-focused land-cover classification workflow that fuses Landsat 9 optical imagery and PALSAR-2 L-band SAR across a ≈2,500 km² study area in Jambi Province, Sumatra, Indonesia, to enhance discrimination of crop systems and improve spatial coherence via object-based enhancement. A 22-class land-cover taxonomy was supported by 14,029 strategically collected training points. Feature engineering produced 29 predictor variables, including conventional vegetation indices, agricultural-specific metrics, water indicators, and SAR-derived structural features. Models were evaluated on an independent test dataset comprising 4,209 samples. An agriculture-weighted Random Forest classifier with strategic class weighting was implemented and followed by Simple Linear Iterative Clustering (SLIC) object-based enhancement to suppress speckle and enforce spatial contiguity. The classification achieved an overall accuracy of 53.7%, with exceptional performance for estate crop systems (F1 = 94%) and reliable forest discrimination. SLIC reduced salt-and-pepper noise by 99.5% and substantially improved spatial coherence metrics, transforming fragmented pixel-based outputs into operationally viable products. Despite these gains, discriminating smallholder mosaics remains challenging and likely requires additional temporal or higher-resolution inputs.

Abstract

The implementation of a Web-Based Library Information System at the Rantauprapat Public Library aims to increase efficiency and effectiveness in managing library resources. This information system integrates various library functions, such as book cataloging, borrowing, returns, and member management, into a single web-based platform. By using web-based technology, libraries can make access easier for visitors to search for information and borrow online, without being limited by time and place. This research identifies the system's technical and functional requirements and evaluates its impact on library services and visitor satisfaction. The results of implementing this system show an increase in data accuracy, a reduction in service times, and a reduction in administrative errors. Apart from that, this system also makes it easy for visitors to access library information more efficiently. It is hoped that the implementation of this web-based library information system can become a model for other libraries in an effort to improve the quality of library information services in the digital era.

Abstract

The development of information technology and data analytics has encouraged business actors to leverage historical data as a basis for decision-making. In the small and medium enterprise (SME) sector, particularly in the culinary field, the ability to predict sales is a crucial aspect of production planning and stock management to ensure operational efficiency. Rayyan Bakery Simpang Marbau, as a bakery SME, faces challenges due to fluctuating sales that have traditionally been managed based on experience rather than systematic data analysis. The main problem addressed in this study is the absence of a data-driven sales prediction method that can assist the business owner in estimating sales accurately. Therefore, a predictive approach that utilizes historical sales data is required to support managerial decision-making. This study employs linear regression and decision tree methods. The analyzed data consist of historical sales records of Rayyan Bakery Simpang Marbau over a specific period. Linear regression is used to model the linear relationship between sales variables, while the decision tree captures non-linear patterns and produces easily interpretable decision rules. The performance of both methods is analyzed and compared based on the accuracy of the predictions they generate. The results indicate that both linear regression and decision tree methods can be effectively used to predict sales; however, the decision tree provides greater flexibility in capturing fluctuating sales patterns. These findings are expected to assist Rayyan Bakery in production planning and stock management, as well as serve as a reference for applying sales prediction methods in similar SMEs.

Abstract

The rapid development of information technology has pushed various business sectors, including Aman Store Rantau Prapat, to adapt digital technology to enhance operational efficiency and market reach. Currently, Aman Store still relies on a manual system, which results in inefficiencies in monitoring transactions and stock, as well as a limited market reach. This research aims to design and build a web-based shoe sales information system using PHP and a MySQL database. The system development follows the Waterfall method, which includes stages of requirement analysis, system design, implementation, testing, and maintenance. System modeling is represented using the Unified Modeling Language (UML), including Use Case, Activity, and Sequence Diagrams, to visualize actor-system interactions and business processes. The result of this research is a web-based application that provides digital product catalogs, online ordering and payment features, and automated stock management. Implementation of this system is expected to accelerate the transaction process, reduce human error, and expand market coverage beyond the local area, thereby increasing the store's competitiveness.
