The development of information technology has increased the need for efficient and accurate athlete data management systems. In Ju-Jitsu, the athlete classification process is still performed manually, making it prone to errors and time-consuming. This study develops a web-based Ju-Jitsu athlete classification system capable of automatically grouping athletes based on weight, gender, and age in accordance with official competition regulations. The system was developed using the Agile method, with React.js for the frontend and Node.js with Express.js for the backend. Classification rules were implemented in a structured manner to ensure consistent calculations and reduce manual errors. System testing using Black Box Testing achieved a 100% success rate, while expert validation produced scores of 3.55 in the first iteration and 3.7 in the second iteration, indicating that the system functions properly and is feasible for use. The system effectively improves the accuracy, consistency, and efficiency of the athlete classification process and supports better data management during competitions

Diversification of food sources is crucial for enhancing national food security. Potatoes are an accessible source of carbohydrates for households; nevertheless, their prices frequently exhibit significant volatility. This study aims to examine the determinants affecting the demand for potatoes. The study was performed in East Java Province, utilizing secondary data from the Central Bureau of Statistics, namely the National Socioeconomic Survey (SUSENAS) for 2023. The study's sample size included 32,454 households. The data analysis employs a Multiple Linear Regression. The research findings indicate that the primary carbohydrate source for households is rice (78.5%), followed by wheat flour (36.7%) and subsequently potatoes (25.8%). The prices of potatoes, rice, shelled corn, cassava, and sweet potatoes affect the demand for potatoes. Simultaneously, the prices of sticky rice, wheat flour, sago, taro, and gaplek do not affect the demand for potatoes. Household income exerts a positive and significant influence on potato demand. The quantity of household members does not influence the demand for potatoes. Substitutes for potatoes include rice, cassava, and sweet potato, whilst corn is a complement to potatoes. This study's findings indicate that households in East Java utilize potatoes as a carbohydrate source alongside rice, particularly as household income rises.

This research presents the development of SiPuTiH (Handwritten Hijaiyah Character Recognition System) using the Convolutional Neural Network (CNN) algorithm to address the challenges of handwriting variability in Arabic scripts. The methodology includes dataset acquisition and preprocessing, CNN architecture design, model training, and performance evaluation. The dataset consists of 1,680 handwritten images representing 30 Hijaiyah characters, divided into 80% training and 20% testing data. The proposed CNN architecture employs four convolutional and pooling layers with a total of 6.8 million trainable parameters. Experimental results show that SiPuTiH achieved a 99.7% accuracy rate in recognizing Hijaiyah characters, with only one misclassification between ‘ta’ (ت) and ‘tsa’ (ث) due to morphological similarity. The trained model was implemented in an interactive Streamlit-based application that includes learning modules, quizzes, and real-time handwriting prediction. SiPuTiH demonstrates high reliability not only as a handwriting recognition system but also as an engaging educational platform for learning Arabic letters. This study confirms the effectiveness of CNNs in handling the morphological complexity of Hijaiyah characters and contributes to the development of intelligent educational tools. Future work may explore larger datasets, transfer learning architectures, and contextual (word-level) recognition to enhance system scalability and performance.

This study examines the role of symbolic interactionism within Integrated Marketing Communication (IMC) at Batik Nimas Sekarsari Gandusari Blitar (BNSGB), Indonesia. In a competitive business landscape influenced by technological advancement and shifting consumer behaviour, small enterprises must employ integrated approaches combining advertising, sales promotion, direct marketing, and personal selling. This qualitative descriptive research explores how BNSGB integrates IMC strategies to promote its products, strengthen its brand image, and build trust among consumers. Data were collected through interviews, observation, documentation, and literature review. The findings show that BNSGB effectively utilizes social media, exhibitions, promotional discounts, and institutional collaborations to engage consumers and expand market reach. Through the lens of symbolic interactionism, the study highlights how producers and consumers create shared meanings through communication symbols, both verbal and non-verbal, that shape perceptions and influence buying decisions. The interaction between sellers and buyers fosters mutual understanding and enhances marketing effectiveness. Ultimately, this study demonstrates that symbolic interactionism provides a deeper understanding of how communication strategies contribute to sustaining consumer loyalty and preserving the cultural and economic significance of traditional batik entrepreneurship.

Vocabulary learning is a fundamental component of language mastery, as it underpins students’ ability to communicate effectively and comprehend texts. With the rapid advancement of technology, Mobile-Assisted Language Learning (MALL) has emerged as an innovative approach that enables flexible, accessible, and interactive learning experiences. However, despite its potential benefits, many university students still face challenges in expanding their English vocabulary due to limited study time, low motivation, and the lack of engaging learning resources. This study aims to explore university students’ experiences in learning English vocabulary through MALL. Employing a qualitative exploratory design, ten students from the Management Study Program at on of the private universities in Indonesia who were enrolled in an English for Specific Purposes (ESP) course participated in the research. Data were collected through semi-structured interviews and participatory observations, then analyzed using thematic analysis to identify recurring patterns and themes. The findings revealed five main themes: (1) flexibility of time and place in learning, (2) increased motivation and engagement through gamified features, (3) independent learning strategies in vocabulary acquisition, (4) technical challenges and digital distractions, and (5) the need for support from lecturers and the academic environment. Students valued the flexibility and autonomy MALL offered, as well as the motivation gained from interactive and gamified elements. Nevertheless, issues such as unstable internet connections and distractions from social media often hindered learning consistency. The study concludes that MALL enhances flexibility, motivation, and learner autonomy in vocabulary learning, yet its effectiveness depends on students’ self-discipline and institutional support. It underscores the essential role of lecturers in guiding and integrating MALL effectively into classroom instruction.
