The goal of this community service program (PkM) at SMA Negeri 11 Samarinda is to increase students' enthusiasm for reading by providing them with e-books that are based on QR codes. Students' lack of enthusiasm for reading and resources for reading led to the program's inception. E-books with QR codes embedded were presented as a workable approach to digital literacy that caters to the needs of students who were born into the digital age. Several steps were involved in the process, such as determining requirements, creating an e-book, creating QR codes, installing them at key school locations, and finally, monitoring and evaluating the results. Observations and questionnaires were given to 200 students as part of the assessment. Students' interest in and ability to access literature were both enhanced by the usage of QR Codes, according to the findings. In a survey, 82% of people said QR Codes were simple to use, and 85% said they were more motivated to read after using them. In terms of reading frequency, 76% of students saw an improvement, and 72% said they could understand what they read better.With an overall mean score of 4.35 (categorized as excellent), the digital literacy program proved to be effective and positively received. Overall, the implementation of QR Code–based e-books successfully strengthened digital literacy practices and created a more engaging, flexible, and sustainable reading experience, offering a model for digital literacy initiatives in other schools.

The concept of money in Islamic economics is grounded in the understanding that money is not merely a medium of exchange but a trust that must be managed according to the principles of justice, benefit, and ethical conduct. In this perspective, money cannot be treated as a commodity traded solely for profit without supporting real economic activities, making practices such as usury (riba), excessive uncertainty (gharar), and hoarding incompatible with Islamic values due to their potential to create inequality and economic instability. Islamic economics emphasizes that the circulation of money must be connected to the real sector to generate added value and support sustainable economic growth. Furthermore, the management of money aims to promote fairness and social balance through mechanisms such as zakat, infaq, and charity. Thus, the Islamic view of money provides an ethical foundation and practical framework for developing a financial system that is stable, inclusive, and oriented toward societal well-being.

This research examines the analysis of Return on Equity (ROE), Quick Ratio (QR), and Debt to Equity Ratio (DER) on corporate valuation, as assessed by Price-to-Book Value (PBV), within technology firms listed on the Indonesia Stock Exchange (IDX) during the period from 2022 to 2024. The primary aim of this investigation is to ascertain the effects of profitability, liquidity, and leverage both in isolation and in conjunction on market valuation in an industry characterized by innovation and intangible assets. This research employs panel data regression analysis utilizing EViews 13 as the quantitative methodology. The findings reveal that ROE significantly enhances PBV, indicating that investors place considerable importance on firms that are capable of generating substantial returns on equity for shareholders. Conversely, QR and DER appear to have no discernible impact on PBV. This observation can be attributed to the unique nature of technology companies, wherein investors prioritize factors other than short-term liquidity and leverage. Nonetheless, when assessed collectively, the three metrics illuminate the variations in corporate value. These results suggest that while financial stability indices exert a positive yet comparatively subdued effect on investor sentiment within the technology sector, profitability remains a paramount determinant. The study elucidates the financial determinants that influence corporate value in innovation-driven industries, providing valuable insights for managers and investors alike.

Hasil pengujian menunjukkan sistem mampu melakukan kontrol suhu dan kelembaban dalam ruang multi-kubikel serta mengirimkan notifikasi melalui Telegram dengan tingkat keberhasilan 100% dan rata-rata delay 5,6 detik.

Relational databases store information in interconnected tables and are widely used for data management and retrieval. However, in certain environments, the original values stored in a relational database cannot be exposed during data retrieval. This limitation creates a challenge because common encryption methods only transform data for storage and do not support mathematical operations needed for value matching. Partially Homomorphic Encryption is a cryptographic approach that allows specific mathematical operations to be performed directly on transformed data without restoring it to its original form. This study proposes the use of Partially Homomorphic Encryption to enable value-based data retrieval while keeping all stored values in their transformed form throughout the entire process. The method relies on homomorphic properties that allow mathematical comparison to be conducted on encrypted data, making the retrieval process possible without revealing the original values. The results show that this approach can perform data retrieval operations in a relational database while preserving the transformed structure of the stored data. The proposed method offers an alternative for environments that require data retrieval without exposing original values and demonstrates the potential of homomorphic techniques in supporting secure and functional data processing in relational database contexts.

The results of the mentoring program indicate that the teachers have a good foundation in writing scientific papers. However, they are still hampered by busy administrative routines. The training aims to stimulate writing enthusiasm and bridge the realization of book chapters among teachers. This mentoring is expected to have a positive impact on improving the quality of teachers' scientific work and improving the learning process at school. In addition, this program also aims to build a sustainable writing culture among educators.

This study aims to analyze the bread production system of UMKM Roti D’One using the Input–Process–Output (IPO) approach and to identify product defects through the application of the Seven Tools of quality control. Data were obtained through interviews, field observations, and production recording. The IPO analysis shows that the production process is carried out manually and relies heavily on worker skills and household-scale equipment. Based on the checksheet, two dominant types of defects were identified—non-soft texture and uneven color—resulting in 30 defective products out of 1,400 breads produced in one week. The Pareto analysis indicates that texture defects contribute the largest portion (56.7%) of total defects. Meanwhile, the fishbone diagram reveals that the main causes originate from raw material inconsistency, equipment limitations, variations in worker skills, and manual production methods. This study suggests improvements related to raw material standards, production consistency, and worker training to reduce defects and enhance the overall quality of Roti D’One products.

This study aims to improve the effectiveness of facility arrangement at Pabrik Oncom Bu Nana by analyzing interactions among production activities and designing spatial layouts based on their priority levels. The current layout presents several critical issues, particularly because the equipment sanitation area is combined with the toilet, creating a significant risk of contamination and reducing hygiene during production. In addition, irregular material flow and excessive worker movement lead to inefficient work processes and may affect the quality of the final product. To address these issues, this study employs the Activity Relationship Chart (ARC) to evaluate the functional closeness among production areas, as well as the Total Closeness Rating (TCR) to determine facility placement priorities based on the intensity of inter-stage relationships. The results of the ARC analysis indicate that the fermentation room has the strongest link to the main stages of oncom production, requiring its placement to be closer to the preparation and molding areas. Findings from the TCR further emphasize that fermentation should become the primary focus in the layout redesign. Based on both methods, a more organized layout design is proposed by relocating the fermentation room to the beginning of the production flow, separating the toilet and sanitation room into two distinct areas, and restructuring the storage, molding, and drying spaces. This redesigned layout is expected to enhance cleanliness, improve material flow, and strengthen the operational effectiveness of Pabrik Oncom Bu Nana.
