The coffee shop industry in Indonesia is experiencing rapid growth that requires business owners to optimize data-driven strategies. This study aims to analyze customer preferences at Semanis Coffee and Resto using data mining methods  to support more effective business decision-making. The method used is Market Basket Analysis with the FP-Growth algorithm for association rule mining and the K-Means algorithm for customer segmentation. The research data consists of 672 sales transactions during the March-May 2025 period. The results of the association analysis with a minimum support of 0.004 and a minimum confidence of 0.2 resulted in five valid rules with a lift ratio above 1. The strongest rule is the combination of Americano→Milk Choco with a confidence of 42.9% and an elevator ratio of 5.229, indicating a strong linkage between products. The most popular products are Milk Choco (10.8%) and Americano (8.5%). Customer segmentation analysis identified three clusters: Cluster 0 (Loyal Customers) 80% with high frequency but low transaction value; Cluster 1 (Occasional Customers) 10% with low activity; and Cluster 2 (Large Buyers) 10% with high transaction value but low frequency. This study concludes that product bundling strategies, loyalty programs, reactivation campaigns, and premium services can be applied to increase the effectiveness of coffee shop businesses.

Libraries play a crucial role in broadening the public's knowledge horizons by improving literacy skills. However, the reality at the Samaturu Library in Jambu Malea Village shows that manual management still dominates, leading to various administrative obstacles such as data irregularities, the risk of losing important information, and inefficiencies in tracking daily activities. This condition demands digital transformation to optimize public services at the village level comprehensively and sustainably. This research focuses on the development of a web-based library information system specifically designed to modernize administrative processes to be more systematic, fast, and organized. Built using the PHP programming language and MySQL database, this platform offers an intuitive interface for both staff and members. Its superior features include book data management, membership, activity agendas, announcements, and digitizing the borrowing and return process. Furthermore, the system is capable of automatically generating periodic reports to facilitate library performance evaluation. Based on the results of comprehensive testing using the Black Box Testing method, all system functionality was proven to operate optimally according to the required specifications. Direct user trials also showed very positive responses regarding aspects of ease of navigation and operational time efficiency. The implementation of this system is expected to improve the effectiveness of internal management, accelerate the quality of services to library users, and become a major catalyst in realizing superior digital literacy governance in rural areas.

The rise of the digital business era presents both opportunities and challenges for SME operators, particularly regarding legal aspects of business and unfair competition. This community service initiative aims to enhance the legal literacy and capacity of SME operators in Surakarta through educational and practical legal support. The methods employed included a pre-test to measure initial understanding, a legal needs assessment to identify participants’ legal requirements, the presentation of materials and interactive discussions as forms of intervention, and a post-test to evaluate improvements in understanding. The results of the activity demonstrated a significant improvement in participants’ legal knowledge and awareness, particularly regarding business contracts, digital transactions, and the risks of unfair competition. Furthermore, there was a shift in participants’ mindset, as they began to view the law as a strategic tool in running their businesses. Nevertheless, this initiative still faces challenges such as time constraints and the need for more intensive follow-up support. Consequently, legal support based on the actual needs of MSME operators has proven effective and requires continuous development to strengthen the competitiveness and legal protection of MSMEs in the digital age.

The rapid digital transformation in educational institutions demands an efficient student grade data processing system capable of handling workloads responsively. This study aims to analyze and compare the efficiency of sorting algorithms (Merge Sort and Quick Sort) and searching algorithms (Linear Search and Binary Search) on a web-based platform. The research method employed is laboratory experimental, testing algorithm performance across various data volume stratifications, ranging from 50 to 1000 entities, using the V8 JavaScript engine. Research findings indicate that Quick Sort possesses superior speed compared to Merge Sort due to its efficient in-place sorting architecture, which minimizes memory overhead and Garbage Collection activity. Furthermore, a performance anomaly was discovered where the Just-In-Time (JIT) Compiler mechanism optimizes execution on large data volumes through a warm-up phase. In the searching aspect, Binary Search demonstrates superior O(log n) logarithmic stability compared to Linear Search, which risks causing interface freezing on massive data. The implication of this study is the critical importance of implementing data pre-sorting protocols to exploit logarithmic search speeds to ensure academic information system scalability. The integration of appropriate algorithms proves to be a crucial foundation in maintaining web application responsiveness amidst the ever-increasing escalation of educational data.

This study aims to evaluate simple bookkeeping practices in traditional Micro, Small, and Medium Enterprises (MSMEs) through a comparative study between Nasi Padang and Warung Madura MSMEs. The background of this study is based on the still low level of financial literacy of MSMEs, especially in terms of recording and managing business finances, which are often not done systematically. The methods used in this activity include direct observation, simple bookkeeping training, and evaluation of the implementation of financial recording. The results of the observation indicate that Nasi Padang MSMEs have not kept complete financial records and still mix personal finances with business finances. Meanwhile, Warung Madura MSMEs have kept simple bookkeeping and separated business finances from personal finances, but the records are not organized neatly and systematically. The implementation of simple bookkeeping training has a positive impact on improving business actors' understanding in recording cash inflows and outflows and preparing simple profit and loss reports. The evaluation results show an increase in the ability of MSMEs to manage business finances in a more structured manner. Thus, simple bookkeeping plays an important role in increasing financial transparency, assisting business decision-making, and supporting the sustainability of MSMEs. This study recommends ongoing mentoring so that simple bookkeeping practices can be consistently implemented by MSMEs.

The transformation of payment systems from cash to digital through the Quick Response Code Indonesian Standard (QRIS) is part of financial transaction modernization in Indonesia. This transformation has begun among Micro, Small, and Medium Enterprises (MSMEs) in the Baduy community, particularly in Baduy Luar, which has higher interaction with external communities. However, the adoption of digital payment systems has not been fully supported by adequate financial management capabilities. This community service activity aims to identify the transformation process of payment systems and describe the financial literacy conditions of Baduy MSMEs. The method used is a descriptive qualitative approach through in-depth interviews and field observations. The results show that some MSMEs have adopted QRIS through Bank BRI as an alternative payment method alongside cash and have utilized social media such as TikTok Live and Instagram for product marketing. The main sources of income include handicrafts, traditional clothing, accessories, and food products. However, financial management practices remain simple and lack systematic recording. This indicates improved financial inclusion but not yet accompanied by adequate financial behavior. Therefore, strengthening financial literacy is essential to support sustainable financial modernization in the Baduy community.

This community service activity aimed to enhance human resource management (HRM) literacy among congregation members through weekly religious study sessions at Kramatwatu Mosque. HRM literacy is important not only in formal work environments, but also in family life, social organizations, and religious activities. The problem identified was the congregation’s limited understanding of basic HRM concepts, such as planning, organizing, role distribution, discipline, communication, and individual potential development. The community service program was carried out through an educational-participatory approach in the form of material presentation, interactive discussions, simple case studies, and reflection on Islamic values relevant to human resource management. The activity was implemented gradually in weekly religious study forums by taking into account the characteristics of the congregation. The results showed an improvement in the congregation’s understanding of the importance of HRM in daily life, particularly in the aspects of responsibility, cooperation, discipline, and self-capacity development. Weekly religious study sessions proved effective as a medium for community empowerment because they were able to integrate religious values with practical HRM concepts. Therefore, strengthening HRM literacy through weekly religious study sessions can serve as a relevant educational strategy to improve mosque-based human resource quality.

This research is based on the reality that classroom management often tests teachers' emotional stability, especially when dealing with highly active students. This study focuses on how teachers use emotional intelligence to control themselves when facing challenging learning situations. The purpose of this study is to describe the forms of emotional regulation carried out by teachers and their influence on the effectiveness of classroom management. The research was conducted using a qualitative descriptive approach through observations and interviews with teachers. The results show that effective emotional management is carried out through several methods, such as increasing self-awareness to recognize stress triggers, pausing before responding to student behavior, and trying to understand the background of student activity through empathy. Teachers with good emotional intelligence tend to be able to direct student activity into more positive learning participation, rather than responding to it with reactive or authoritarian responses. This study emphasizes the importance of strengthening psychological aspects and emotional management skills in teacher professional development programs. Emotional maturity not only helps create a more harmonious classroom atmosphere but also forms the basis for inclusive learning interactions and supports the continuous development of student character.

Pumpkin seeds (Cucurbita spp.) are a byproduct of pumpkin that has great potential to be developed as a functional food ingredient due to their high nutritional content and bioactive compounds. This article aims to examine the valorization (utilization) of pumpkin seeds in various food products and their potential as a functional food. The method used was a narrative literature review through a search of the Google Scholar, ScienceDirect, PubMed, and MDPI databases for the period 2016–2026. The results of the study indicate that pumpkin seeds have been applied in various food products such as cookies, crackers, bread, biscuits, cakes, muffins, and snack bars. The addition of pumpkin seeds generally increases the content of protein, fiber, unsaturated fatty acids, minerals, and bioactive compounds that contribute to antioxidant activity. However, increasing the proportion of pumpkin seeds also affects the physical and sensory characteristics of the product, such as darker color, decreased volume, and changes in texture due to reduced gluten content in the dough. Therefore, formulation optimization is needed to achieve a balance between increasing nutritional value and consumer acceptance. Overall, pumpkin seeds have the potential to be used as an ingredient in the development of functional foods.

Learning fiqh is a very important thing to learn because fiqh regulates all the laws of Allah related to human work where the laws are taken from the Qur'an and Sunnah by means of ijtihad. However, in the field there are still many students who do not understand how to perform tayammum taharah correctly. This happens due to lack of understanding and insufficient habits. Thus, this PKM activity aims to educate students related to taharah so that students not only understand theory, but can apply it in daily life according to Islamic law. The method used is Asset Based Community Development (ABCD) with the stages of discovery, dream, design, define, and destiny. To optimize local potentials such as the competence of ustazah and TPQ facilities, through lectures, demonstrations, discussions, hands-on practice, and evaluation based on interactive quizzes. The results of the tayammum mentoring activities show that TPQ Darul Falah students are very active and interactive during learning. Students who initially did not understand the procedures of tayammum properly and perfunctorially, are now able to do it according to Islamic law. In addition, this training activity provides direct understanding and experience to ustazah and students of TPQ Darul Falah in learning tayamum practice.
