PERBANDINGAN KINERJA SVM, KNN, DAN NAÏVE BAYES PADA ANALISIS SENTIMEN TWEET MBG

2025-12-26T01:48:46+00:00

This study explores the effectiveness of three machine learning classifiers—Support Vector Machine (SVM), K-Nearest Neighbor (KNN), and Naïve Bayes—in analyzing public sentiment toward the Free Nutritious Meal Program using data from the X (Twitter) platform. Tweets were collected via Tweet Harvester by applying keyword-based filtering over the August–October 2025 period. Prior to model implementation, the textual dataset underwent comprehensive preprocessing, including data cleaning, case normalization, lexical standardization, tokenization, stopword elimination, and stemming. Sentiment labels were generated using a lexicon-based approach to distinguish between positive and negative opinions. The processed data were divided into training and testing subsets for classification. Model performance was evaluated using accuracy metrics derived from the confusion matrix. The results show that SVM outperformed the other models with an accuracy of 91.7%, followed by Naïve Bayes at 79.6% and KNN at 79.3%, indicating the strong capability of SVM in handling complex textual representations in social media sentiment analysis.

SISTEM INFORMASI MONITORING OUTPUT ASSEMBLY BERBASIS WEB DI CLEANROOM DENGAN METODE SCRUM

2026-01-20T13:37:21+00:00

The development of manufacturing industries operating in cleanroom environments requires a production monitoring system that is accurate, fast, and well integrated. Manual monitoring of output assembly using paper forms or spreadsheets often leads to delays in information delivery, data recording errors, and difficulties in decision making. These limitations are critical because cleanroom production processes demand high accuracy and strict control. This study aims to design and develop a web-based output assembly monitoring information system that provides real-time and structured production data. The research applies a Research and Development (R&D) approach using the Scrum software development method. Research stages include problem identification, literature review, system requirements analysis, system design, prototype development, and system testing. The system is developed using web-based technology with a centralized database to support data input, processing, and information presentation. The results show that the proposed system improves information accessibility, minimizes data recording errors, and provides real-time visualization of production performance through a monitoring dashboard. In conclusion, the developed system effectively supports output assembly monitoring in cleanroom environments and enables faster and more accurate production decision making.

2026-01-19T07:00:22+00:00

The availability of transaction data in culinary SMEs offers opportunities for data-driven decision-making, yet it is often underutilized. This study proposes a Smart Pricing and menu bundling recommendation system for Moon Cafe Batam using data intelligence. The research applies the CRISP-DM framework to analyze historical transaction data from a POS system. The FP-Growth algorithm is used to identify frequent itemsets and association rules that represent customer purchasing patterns. These patterns are combined with Cost of Goods Sold (COGS/HPP) calculations to generate menu bundling and pricing recommendations that consider profitability. The system is implemented as a web-based application using React.js, PHP, and MySQL, and evaluated through black-box testing. The results show that the system can support structured menu bundling analysis and pricing simulations, enabling managers to make more objective and data-driven decisions in culinary SMEs.

ANALISIS KUALITAS LAYANAN PEMESANAN TIKET ONLINE TAMAN HIBURAN MENGGUNAKAN METODE SERVQUAL STUDI KASUS: (TRANS STUDIO, DUFAN, TMII)

2025-07-31T06:47:53+00:00

The advancement of digital technology has driven many amusement parks to offer online ticket booking services. However, the quality of these services still raises concerns, such as unfriendly user interfaces, delayed payment confirmations, and slow customer service responses. This study aims to analyze the quality of online ticket booking services at three major amusement parks—Trans Studio, Dunia Fantasi (Dufan), and Taman Mini Indonesia Indah (TMII)—and measure the gap between user expectations and perceptions using the SERVQUAL method. This quantitative research involved distributing questionnaires to 390 respondents. The research instrument is based on five SERVQUAL dimensions: Tangibles, Reliability, Responsiveness, Assurance, and Empathy. The results reveal that all three amusement parks showed negative gap scores, indicating that the services did not meet user expectations. TMII recorded the highest average gap of - 0.44, while Trans Studio had the smallest gap of -0.27, making it the park with the best perceived service quality. Assurance and Reliability were identified as the most problematic dimensions. This study contributes by helping amusement park managers evaluate and improve their digital service systems to better meet customer expectations.
