Abstract

The increasing demand for efficient and accessible academic services has led higher education institutions to adopt innovative digital solutions. At STMIK Mulia Darma, students often experience delays and limited access to academic information due to manual service systems and limited staff availability. To address these challenges, this research proposes the development of an academic chatbot using Natural Language Processing (NLP) to automate and enhance student services. The chatbot is designed to understand and respond to student inquiries in Bahasa Indonesia, providing real-time information related to course schedules, registration procedures, tuition deadlines, and other academic matters. By integrating NLP with the institution’s academic information system, the chatbot delivers personalized and context-aware responses. The system was developed using a rule-based NLP model enhanced with intent classification and entity recognition techniques. Testing results indicate that the chatbot successfully answered more than 90% of user queries with acceptable response time and accuracy. This solution demonstrates the potential of NLP-powered chatbots to improve service efficiency, reduce administrative workload, and support the implementation of a smart campus ecosystem.

Abstract

Active involvement of church youth in ministry is essential for fostering spiritual growth and creativity among Christian youth. In today's digital era, social media serves as a powerful platform to promote church activities in an engaging and modern way. However, many youths lack the skills to design content that is visually appealing and aligned with digital trends. This community service activity aimed to enhance the ability of the youth at GPP Church, Jl. Pelajar, Medan, in creating creative social media content using design applications such as Canva and CapCut. The implementation method included initial observation, hands-on training, mentoring, and evaluation of the participants' work. The results showed high enthusiasm from the participants and their ability to produce creative content in the form of posters, reels, and promotional church event designs. This training successfully improved their understanding and skills in designing and using social media positively to support church events and outreach. Furthermore, it empowered the youth to become creative digital ambassadors for the church, staying relevant to current technological developments.

Abstract

The community service program entitled "Digitalization of MSMEs: Helping Small Businesses Use Technology" aims to increase the capacity of Micro, Small and Medium Enterprises (MSMEs) in utilizing digital technology to optimize operations and expand their market reach. MSMEs play an important role in the Indonesian economy, but often face challenges in adopting digital technology due to limited knowledge and resources. The program involves intensive training and hands-on mentoring on the use of digital technology, including online marketing tools, inventory management systems, and e-commerce platforms. The methods used include practical training sessions, workshops and individual mentoring. Evaluations show that participants experienced significant improvements in their technology understanding, digital skills and business performance. The program recommends the need for continued support and better access to technological resources to ensure the success and sustainability of MSME digitalization in the future.

Abstract

Penelitian ini bertujuan untuk menganalisa Pengaruh Minat Belajar, Motivasi Belajar, Perilaku Belajar Terhadap Pemahaman Akuntansi Dengan Kecerdasan Spritual Sebagai Variabel Moderating Pada Mahasiswa Universitas Imelda Medan. Minat belajar seseorang yang rendah untuk mengawali suatu kegiatan akan memiliki rasa malas dan tidak tertarik untuk melanjutkan aktivitasnya tanpa diimbangi motivasi belajar yang kuat dan semangat menyebabkan konsentrasi dan perhatian terhadap pelajaran akan menurun sehingga perilaku belajar yang rendah akan mencerminkan sikap kurang baik dari diri mahasiswa dalam menanggapi dan meresponi setiap kegiatan belajar mengajar yang terjadi, dan tidak bertanggung jawab atas kesempatan belajar yang diberikan kepadanya.. Variabel yang digunakan dalam penelitian ini adalah minat belajar, motivasi belajar dan perilaku belajar sebagai variable independen, pemahaman akuntansi sebagai variabel dependen dan Kecerdasan Spritual sebagai variable moderating. Jumlah populasi dalam penelitian ini sebanyak 220 mahasiswa. sampel yang digunakan adalah sebanyak 110 mahasiswa dengan menggunakan teknik penarikan sampel dengan metode Cluster Random Sampling. Kecerdasan spiritual bukan merupakan variabel moderating yang dapat memperkuat hubungan antara Minat Belajar, Motivasi Belajar, Perilaku Belajar terhadap Pemahaman Akuntansi Maka peningkatan minat oleh mahasiswa dapat diupayakan melalui peningkatan pemahaman tentang akuntansi secara mendalam. Perilaku belajar yang sesuai dengan tujuan pendidikan, dimana dengan perilaku belajar tersebut tujuan pendidikan yang dapat dicapai secara efektif dan efisien, sehingga prestasi akademik dapat ditingkatkan

Abstract

This study aims to analyze the influence of intellectual intelligence, learning motivation, and learning behavior on the learning interest of students in the Information Management Study Program at STMIK Mulia Darma. Higher education institutions play a strategic role in improving the quality of human resources, particularly in shaping intellectual and professional abilities. However, various problems still exist, including low-quality educators, limited educational facilities, and weak links between education and the needs of the workforce. Intellectual intelligence without the support of positive motivation and learning behavior cannot produce an optimal learning process. Students with low motivation and learning behavior tend to show a lack of responsibility and participation in academic activities. This study uses the Structural Equation Modeling (SEM) approach with the Partial Least Squares (PLS) method to test the relationship between latent variables. The results of this study are expected to contribute to efforts to improve the quality of learning and develop student interest in learning in higher education.

Abstract

This research aims to produce an optimal course schedule at STMIK Mulia Darma, with the aim of reducing the number of conflicting courses, equalizing the student burden, and maximizing the use of classrooms. The optimization process is carried out through determining the course schedule using a genetic algorithm. Genetic algorithms were chosen because of their ability to solve large-scale and complex problems, making them suitable for handling complex course scheduling problems that involve many variables and constraints. It is hoped that the results of this study will produce an optimal course schedule, taking into account course clashes, student loads, and classroom use efficiency. After research, the optimal course schedule was obtained.

Abstract

Financial literacy and personal cash flow management are critical components of individual economic stability. However, the volatility of daily transaction patterns often complicates manual monitoring, leading to liquidity deficit risks. This study aims to develop a Decision Support Model for personal cash flow monitoring by comparing the effectiveness of AutoRegressive Integrated Moving Average (ARIMA) and Holt-Winters Exponential Smoothing methods. Using the ANZ Virtual Internship transaction dataset, this research processes historical customer daily balance data through preprocessing, stationarity testing, and predictive modeling stages. Performance evaluation results demonstrate that the Holt-Winters method is more accurate in capturing customer balance trends with a Mean Absolute Error (MAE) of AUD 476.80 and a Root Mean Square Error (RMSE) of AUD 568.96, outperforming ARIMA which yielded higher error rates. Based on these results, the Holt-Winters algorithm is integrated into an Early Warning System (EWS) logic that maps balance predictions into three risk zones: Safe, Warning, and Critical. The proposed model is capable of providing future financial health status visualization as a risk mitigation instrument for banking customers
