Abstract

Penelitian ini merupakan tinjauan literatur sistematis yang bertujuan untuk menganalisis secara mendalam penerapan algoritma klasifikasi dalam data mining untuk memprediksi loyalitas pelanggan pada platform e-commerce. Penelitian dilakukan menggunakan metode Systematic Literature Review (SLR) yang mengacu pada panduan PRISMA. Sebanyak 15 artikel ilmiah terpilih dari periode 2018 hingga 2025 dianalisis berdasarkan jenis algoritma, metode, serta hasil evaluasi model. Hasil studi menunjukkan bahwa algoritma seperti Naïve Bayes, C4.5, Random Forest, dan Deep Learning sering digunakan karena keunggulan masing-masing. Naïve Bayes efektif untuk data sederhana dan cepat diimplementasikan, sedangkan C4.5 unggul dalam memberikan interpretasi yang mudah dipahami. Random Forest memiliki akurasi tinggi dan cocok untuk data besar dan kompleks, sementara Deep Learning mampu mengenali pola perilaku pelanggan yang kompleks tetapi memiliki kekurangan pada transparansi hasil. Selain itu, metode clustering seperti K-Means dan DBSCAN juga penting untuk segmentasi awal sebelum klasifikasi dilakukan. Dengan demikian, penerapan algoritma klasifikasi tidak hanya meningkatkan akurasi prediksi loyalitas pelanggan, tetapi juga mendukung perumusan strategi retensi yang lebih efektif dan personal. Hasil penelitian ini diharapkan dapat menjadi dasar pengembangan penelitian lanjutan dan penerapan praktis di industri e-commerce Indonesia.

Abstract

Expert systems are a branch of artificial intelligence designed to replicate the reasoning ability of specialists. This study applies the forward chaining method to build a web-based expert system for diagnosing laptop malfunctions. The system’s knowledge base was constructed from 20 common laptop malfunction symptoms, identified through literature review, user questionnaires, and interviews with repair technicians, and translated into inference rules. To evaluate performance, the system was tested on 50 malfunctioning laptops. Results show that the expert system achieved an accuracy rate of 85%, indicating its effectiveness in detecting various hardware and software problems. This research demonstrates that forward chaining can support non-expert users in performing early fault detection, thereby reducing repair costs and dependence on professional technicians

Abstract

Village potential-based social entrepreneurship through Village-Owned Enterprises (BUMDes) represents a social business model that optimizes natural resources, cultural assets, and community capacities to address socio-economic issues while increasing Village Original Revenue (PADes). This community service activity was conducted in Muara Tembesi Subdistrict, Batanghari Regency, Jambi, Indonesia. The study aims to analyze the role of Village-Owned Enterprises (BUMDes) in village development and improving community welfare through a social entrepreneurship approach. There are 15 actively operating BUMDes distributed across 12 villages in Muara Tembesi, engaging in various types of business activities. Although these enterprises have achieved progress in managing their business units, they still face several challenges related to social entrepreneurship, including a lack of innovation in the creative economy for resource management, inadequate mapping of village potential, suboptimal utilization of village websites, and limited effectiveness in marketing and promotional channels. Based on these issues, the service team conducted field observations and provided technical assistance to BUMDes managers, carried out village potential mapping, and analyzed appropriate strategies for developing business units and creative economic activities within rural communities. The results of the mapping indicate that each village possesses distinct potentials; however, natural resource outputs are still predominantly concentrated in the agricultural and plantation sectors. Several strategies were proposed to address the challenges faced by BUMDes, including enhancing understanding of the importance of BUMDes for village development, providing training and mentoring in social entrepreneurship and small and medium enterprise management, increasing community awareness of village potential, and encouraging subdistrict and village officials to utilize BUMDes operational funds more effectively.

Abstract

This community service activity aims to improve students’ competencies in the installation and configuration of operating systems through a practice-based approach at Universitas Muhammadiyah Jambi, involving 25 participants. The problem faced by the participants is the low level of practical skills in independently performing operating system installation and configuration, caused by the dominance of theoretical learning and the lack of direct practical experience. Therefore, a learning approach that integrates theoretical and practical aspects in a balanced manner is required. The method used in this activity is hands-on training combined with direct mentoring through the stages of preparation, implementation, evaluation, and follow-up. During the implementation stage, participants were provided with basic materials, demonstrations, and direct practice under the guidance of the implementation team. Evaluation was carried out by comparing pre-test and post-test results as well as observing participants’ skills during the activity. The results show a significant improvement in students’ competencies, indicated by the transition from conceptual understanding to the ability to independently perform installation and configuration of operating systems. In addition, participants demonstrated improvement in basic troubleshooting skills, learning engagement, and confidence during practice. This activity produced outputs in the form of improved technical skills relevant to industry needs and the development of independent problem-solving abilities among students. Therefore, practice-based training methods are proven to be effective in improving student competencies in the field of information technology and have the potential to be further developed in advanced training programs.
