Micro, Small, and Medium Enterprises (MSMEs) play a vital role in supporting regional economic development. However, inefficient inventory management remains a significant challenge in operational effectiveness. This study aims to analyze raw material inventory control at Kebab & Burger Foursist MSME in Tarakan City using the Economic Order Quantity (EOQ) and Reorder Point (ROP) methods. A descriptive quantitative approach was employed, utilizing annual sales data, ordering costs, and storage costs of main raw materials. The results indicate that the implementation of EOQ and ROP effectively determines the optimal purchase quantity and reorder timing, thereby minimizing total inventory costs and reducing the risk of stockouts or overstocking. The use of POM-QM for Windows software enhances the accuracy of the analysis. The implications of this study offer practical solutions for MSME actors in managing raw material procurement more efficiently and systematically.

The rapid advancement of technology and globalization presents challenges for the education sector, particularly in shaping students' character and social skills. Islamic education in the digital era must adapt to learning methods that not only focus on cognitive development (hard skills) but also emphasize the enhancement of soft skills, which include social, emotional, and spiritual aspects. The hybrid IT-based learning method emerges as an innovative approach that integrates face-to-face learning with digital technology to enhance the effectiveness of Islamic education. This study aims to analyze the implementation of the hybrid IT-based method in shaping students' soft skills at SMP Islam Al Azhar Sragen and SMP Islam Al Abidin Surakarta, as well as to identify the supporting and inhibiting factors in its implementation. This research employs a qualitative descriptive approach using a comparative study method, with data collected through observations, interviews, and documentation. The findings indicate that the implementation of hybrid IT-based learning significantly contributes to the development of students' soft skills, such as communication, teamwork, independence, leadership, critical thinking, and responsibility. Key supporting factors include technological infrastructure, teachers’ readiness to utilize digital media, and a school environment that upholds Islamic values. On the other hand, inhibiting factors include limited technology access for some students, low digital literacy among students and parents, and challenges in objectively assessing soft skills. This study provides new insights into the effectiveness of the hybrid IT-based method in Islamic education and offers strategic recommendations for its optimization. The findings are expected to serve as a reference for Islamic schools in developing learning models that align with modern educational advancements while preserving Islamic values in character building.

Electroplating was the process of coating metal surfaces using the electrochemical method. We used alkaline zinc (Zn2+) plating that was anti-corrosion coating, cheapest, evenly adhesion, as well as better-looking crushing. This study aims to test and measure the thickness of the layer on spark plugs with variations in different electrical currents 300, 400, and 500A and increased hours during the coating process, investigate the corrosion resistance of white rust on the surface and analyze the changes in alkaline zinc concentration and temperature that affect the thickness of the layer, respectively. The results, such as 1st sample 13 pcs, 300A, and thickness of 7.26-micron with white rust 9 pcs. 2nd sample 13 pcs, 400A, and thickness of 9.15-micron white rust 5 pcs. 3rd sample 13 pcs, 500A, and thickness of 12.75-micron white rust 3 pcs. The high electric current (500A) and 45 hours of the experiment would influence the lowest white rust corrosion level. The high alkaline zinc solution with an optimum 36°C solution temperature and 500A electric current would undoubtedly deposit the white rust until 3 pcs.

Forensics has become an essential part of the disclosure of criminal evidence. A bioinformatics approach in the form of DNA forensics and digital forensics can be a good combination in disclosing digital-based criminal evidence. This study explains how the role of bioinformatics through the digital approach can be a means of forming new approaches in integration with digital forensics, called cyber-bioinformatics. Despite many hopes and challenges ahead, it does not rule out the possibility of criminal cases related to the privacy of human genomic data, so it proposes a new hypothesis, “cyber-bioinformatics.” The role of cyber-bioinformatics is very central in this regard.
