Abstract

This study applies the K-Nearest Neighbor (K-NN) algorithm to classify customer sentiments from online reviews about Ngeboel Vapestore, a local MSME in the vape industry. A total of 175 reviews from Google Review and Instagram were processed using standard NLP techniques and TF-IDF for feature extraction. The best K-NN model (k=3) achieved 85.4% accuracy. Although Logistic Regression achieved higher accuracy (92.6%), it failed to detect negative sentiment. The findings highlight the potential and limitations of K-NN for sentiment analysis in underexplored MSME contexts like vape retail. The study recommends further model improvements and broader MSME applications.

Abstract

In an increasingly competitive global market, accurately identifying untapped market potential in small to medium-sized regions, often overlooked by traditional single-indicator analyses, presents a significant challenge for strategic decision-making. This study addresses this by proposing a hybrid analytical framework integrating K-Means Clustering with Multi-Criteria Decision-Making (MCDM) methods, utilizing population size and land area as core indicators. The primary objective is to develop a robust market potential analysis model capable of systematically classifying regions and providing actionable insights for resource optimization and market expansion. The methodology involves determining the optimal number of clusters using the elbow method (k=3, with a silhouette score of 0.8862), followed by K-Means clustering to segment Asian countries into distinct groups. Subsequently, three MCDM methods SAW, WP, and WASPAS are applied to rank countries within the most relevant cluster (low population and area) under various weighting scenarios. The results consistently demonstrate Turkey's top ranking across all MCDM methods, highlighting its robust market potential regardless of weight variations. Crucially, a very strong agreement in rankings between the MCDM methods was observed, evidenced by Spearman's correlation coefficients consistently above 0.98, with the highest correlation between SAW and WASPAS (0.998379 for [0.3, 0.7] weights). This high correlation confirms the reliability and consistency of the model, concluding that SAW and WASPAS are highly suitable for this analysis, and identifying Turkey as the leading country in market potential among 50 Asian nations based on the criteria studied.

One of the key units within PKT's organizational structure is the Plant Services Division (Jasa Pelayanan Pabrik or JPP), which is primarily responsible for ensuring the uninterrupted and optimal operation of all plant facilities. JPP provides a range of essential services, including routine maintenance, the production of spare parts, and the upkeep of factory equipment. Vendor selection is a critical stage in the procurement process, as it directly impacts the quality and operational efficiency of the company. However, in practice, the selection process is often still carried out manually, making it vulnerable to subjectivity, inefficiency, and lack of transparency. This study aims to develop a web-based system designed to support the vendor selection process in a more objective, efficient, and structured manner by applying the Analytical Hierarchy Process (AHP) method. AHP serves as the primary decision-making approach in this system, allowing for multi-criteria evaluation based on several key aspects such as price, implementation time, experience, technical proposal quality, and the capability of human resources and equipment. The results of system testing indicate that integrating AHP into a web-based platform significantly accelerates the selection process, minimizes human error, and enhances decision-making accuracy. With the implementation of this system, the company can conduct the tendering process more transparently and efficiently, leading to more optimal outcomes in selecting the best vendor.Keywords: AHP Method; Tender; Company; Vendor.

Abstract

Incoming mail management is an important part of higher education administration because it is related to document storage, classification, and retrieval in a fast and accurate manner. However, the incoming mail archiving process at the General Administration and Finance Bureau (BAUK) of STMIK Widya Cipta Dharma is still carried out manually, making document grouping inefficient, slowing down archive retrieval, and potentially causing inconsistencies in determining mail categories. This study aims to implement the Naïve Bayes algorithm in a web-based incoming mail archiving system to support automatic mail classification. The system was developed using Laravel and Livewire as the main application, and Flask as the classification service. The dataset consisted of 79 incoming mail documents divided into four categories: requests, invitations, notifications, and reports. The preprocessing stage included case folding, text cleaning, tokenizing, stopword removal, and stemming. The results show that the system is able to automatically classify incoming mail and present detailed classification processes through training reports and classification results. Based on testing on 16 incoming mail documents, the model achieved an accuracy of 75.00%, an average precision of 63.89%, and an average recall of 72.22%. These results indicate that the Naïve Bayes algorithm is sufficiently effective in supporting a more structured and efficient incoming mail archiving process.

Abstract

The computer laboratory is one of the important facilities in supporting practical activities and technology-based learning at STMIK Widya Cipta Dharma. This study aims to analyze the level of student satisfaction with the computer laboratory facilities and to determine improvement priorities that need to be addressed. The method used in this study is Importance Performance Analysis (IPA), which measures the relationship between the level of importance and the performance level of each laboratory service attribute. Data were collected through questionnaires distributed to 129 students who use the laboratory. The results show that, in general, students are satisfied with the laboratory facilities, especially in terms of room comfort, practicum module suitability, and software availability. The overall satisfaction level reached 93%, indicating that most facilities have met student expectations. However, several attributes require greater attention, such as internet connection speed, hardware condition, and peripheral functionality including monitors, keyboards, and mice. Based on the IPA Cartesian diagram analysis, these attributes are located in the main priority quadrant for improvement because they are considered highly important but their performance is still below expectations. Meanwhile, attributes related to assistant responsiveness and module clarity were included in the maintain performance quadrant. The findings of this study are expected to provide useful input for laboratory management in improving service quality and optimizing facilities to better support student learning activities.
