Determining classes for outstanding students based on exam results is a crucial step in promoting the improvement of learning quality. This study applied a data mining method using the K-Means Clustering algorithm to group students based on their exam results. The process includes collecting exam score data, preprocessing the data, and applying the K-Means algorithm to form several student groups based on their achievement levels. Through this algorithm, students are clustered into groups with similar characteristics, such as excellent, average, and those requiring more attention. The study's results indicate that the K-Means Clustering approach can provide an accurate representation of the distribution of student abilities, serving as a basis for designing more effective and equitable learning strategies. This implementation is expected to help schools identify students' potential more objectively and enhance overall educational quality.

The COVID-19 pandemic has had a significant impact on the Small and Medium Enterprises (SMEs) sector, including Kirimi dessert, a home store located on Jalan Noja I, Kesiman Petilan Village, Denpasar. This study aims to identify problems and provide solutions for Kirimi dessert MSMEs in facing challenges during the pandemic. The business, which focuses on making mille crepes and various desserts, faces several main obstacles such as limited production space, inability to fulfil orders when demand is high, and lack of promotion and personal branding. The research methodology used a qualitative approach through interviews and discussions with the business owner. The solutions offered include the development of MSME innovation, business expansion, and increased promotion through logo design, packaging, and social media optimisation. The implementation of this solution is expected to help MSMEs increase market reach and sales during the COVID-19 pandemic.
 

The introduction and use of traditional medicine is an alternative step to carry out natural and effective treatment. Traditional medicine has great potential to improve people's health. Not many people use herbs for medicinal purposes, so the community service activity team aims to increase knowledge about Traditional Medicine (Herbal Medicine), especially for teenagers. Currently, teenagers prefer to use modern medicine, so their knowledge and experience regarding traditional medicine are still very lacking. Knowledge about herbal medicine is important for teenagers because it can help them use traditional medicine appropriately. Good knowledge of herbal medicine can also help prevent traditional medicine that can heal from becoming dangerous. The activity method is carried out using education through counseling about the introduction and use of traditional medicine (Herbal Medicine), which is carried out for students at Ummul Quro Al-Hamidiyah Foundation Middle School, Masjid Kyai Muara Ogan Street, Kertapati Palembang. This activity was held on December 19, 2024, with 50 participants from Ummul Quro Al-Hamidiyah Foundation Middle School students. The activity results stated that students understood the counseling about using traditional medicine (Herbal Medicine) well.

With the rapid increase in global population and the ongoing depletion of agricultural land, food security faces an escalating threat. CRISPR genetic engineering technology offers immense potential to enhance crop resilience and productivity. However, its application raises significant ethical concerns, both from a bioethical perspective and within the framework of Islamic values. This article examines core principles of bioethics and Islamic ethics to explore the morally conscious integration of genetic technology. Through a comprehensive literature review, it underscores the necessity of a collaborative approach involving scientists, policymakers, and religious leaders to establish ethical guidelines for its responsible use. The findings highlight the critical need to strike a balance between technological innovation and the preservation of moral principles. By adhering to ethical standards rooted in both modern bioethics and Islamic teachings, genetic technologies such as CRISPR can be harnessed to address food security challenges by improving crop productivity and fortifying resistance to diseases and extreme environmental stressors, without compromising moral integrity.

The structure of the Windows operating system plays an important role in supporting the operational performance of computers, especially in business environments and professional users. This system is designed with a modular and layered architecture, which includes various components such as Hardware Abstraction Layer (HAL), I/O device manager, virtual memory management, and an integrated security system. Windows also supports energy management and plug-and-play mechanisms, which improve power efficiency and hardware compatibility. This architectural approach allows Windows to optimize interactions between hardware and applications, supports multitasking, and provides an efficient user interface. Thus, the structure of the Windows operating system is able to significantly improve device performance, which leads to optimization of operational performance.

Agricultural microbiology plays an important role in supporting the sustainability of the agricultural sector, contributing to global food security. Microorganisms, such as bacteria, fungi and algae, have various roles in increasing soil fertility, controlling plant pathogens and supporting biodiversity. This research aims to explore the role of microbiology in supporting environmentally friendly and sustainable agriculture. Through observations of various applications of microorganisms in agriculture, it was found that microorganisms can function as biopesticides, biofertilizers and organic waste processors. The research results show that microorganisms are able to optimize agricultural yields, improve soil health, and reduce dependence on synthetic chemicals.

This research explores the impact of digitalization on Micro, Small, and Medium Enterprises (MSMEs) using a systematic literature review (SLR) approach based on the PRISMA method. The data collection process began with the identification of relevant scientific articles using the keywords "digitalization," "MSMEs," and "digital transformation," through leading academic databases, such as Scopus, Google Scholar, and JSTOR. The initial search identified 278 articles, of which 35 met the predetermined inclusion criteria. A thorough analysis of these 35 articles revealed that digitalization plays a pivotal role in fostering innovation within the MSME sector, offering benefits such as enhanced operational efficiency, expanded market access, and strengthened social, economic, and environmental sustainability. However, the implementation of digitalization in MSMEs is encumbered by several challenges, including limited resources, uneven digital infrastructure, and cyber security threats. The study underscores the significance of the government's role in establishing regulatory frameworks, offering financial incentives, and fortifying infrastructure to facilitate the sustainable digital transformation of MSMEs. This research provides strategic insights for policymakers, practitioners, and academics, offering guidance on the successful adoption of digitalization in the MSME sector.

Agricultural waste treatment is an organism that offers innovative solutions to reduce the negative environmental impact of waste while increasing agricultural productivity. By using microorganisms such as bacteria, fungi, and actinomycetes, wastes such as straw, manure, and coffee grounds can be effectively treated. This biological process accelerates the decomposition of organic matter into more benign substances and nutrients, such as nitrogen, phosphorus and potassium, which are essential for plant growth. In addition to improving soil fertility, the use of organic fertilizers also reduces dependence on chemical fertilizers, greenhouse gas emissions, and sustainable agriculture. The aim of this study was to investigate the role of microbiology in agricultural waste transformation by examining its mechanisms, potentials, and challenges. The results of this study show that microorganism-based technologies contribute to more environmentally friendly practices and reinforce fundamental economic principles. Processing agricultural waste into organic fertilizer is a strategic step in realizing sector sustainability.
