The use of moldboard plows in agricultural land preparation often faces wear problems on the share component, leading to increased maintenance time and reduced operational efficiency. This study aims to design and analyze a modular concept for the plow share to improve maintenance and repair efficiency without compromising structural performance. The research methods include field observation, component dimension measurement, design modeling using CAD software, and structural analysis using the Finite Element Analysis  (FEA) method. In addition, maintenance ease was evaluated through a questionnaire based on a rating scale. The results show that the modular design significantly improves maintenance and repair efficiency, with an average score of 4.59 categorized as very good. Structural analysis indicates that the modular design reduces maximum stress on the moldboard and slightly decreases deformation, reflecting improved structural stiffness compared to the conventional design. However, the Safety Factor on the share component remains below the acceptable limit, indicating the need for further development. Overall, the modular design provides an effective solution to enhance maintenance efficiency while maintaining the structural performance of the moldboard plow.

This study aims to examine how an online bajaj-based pick-up and drop-off service developed by a kindergarten is implemented. The bajaj application is considered an innovation in a community-based educational transportation system. The limitations of conventional pick-up and drop-off systems in providing optimal efficiency, transparency, and safety form the basis of this research. This study employed a qualitative approach using a case study method, with data collected through observation, interviews, and documentation. The results indicate that the use of the online bajaj application improves service quality through features such as booking services, real-time location tracking,and notifications to parents, which enhance time efficiency, transparency, and a sense of security. Compared to commercial transportation services, the community-based service model allows for more controlled operational management. However, challenges such as low digital literacy among users, limited network infrastructure, and potential data security risks were also identified. Critically, this innovation contributes significantly to the development of the smart mobility concept in the education sector, although it still requires improvement in terms of system sustainability and user data protection.

This study aims to comprehensively evaluate the potential pharmacological activities and safety profiles of seven secondary metabolite compounds (Caffeic Acid, Syringic Acid, Quercetin, Luteolin, p-Coumaric Acid, Ferulic Acid, and Epicatechin) identified in the Bajakah plant (Spatholobus littoralis Hassk.). The research approach integrates in silico analysis using the PubChem database, biological activity prediction via PASS Online, oral toxicity assessment through ProTox-II, and pharmacokinetic evaluation using pkCSM, which were subsequently validated through an empirical literature review. The results indicate that these compounds exhibit significant activity probabilities, particularly as antimutagenic, antiseptic, and antioxidant agents. Luteolin demonstrated the highest antimutagenic potential, while Quercetin showed dominant antioxidant activity. Toxicity profiling revealed that Luteolin and Caffeic Acid possess the highest safety levels (Class 5), whereas Quercetin requires special attention (Class 3). These computational findings strongly correlate with empirical evidence demonstrating that Bajakah extract exhibits broad-spectrum antibacterial activity against Staphylococcus aureus, antifungal activity against Candida albicans, as well as high antioxidant and anti-inflammatory capacities. This study provides a strong molecular foundation for the development of Bajakah as a safe and effective phytopharmaceutical candidate.

Copyright is an exclusive right granted to creators to protect their intellectual works. The importance of copyright protection has increased with advances in digital technology and the widespread use of social media as a means of content distribution. Digital platforms such as YouTube, Instagram, TikTok, and various other streaming services facilitate the distribution of digital works, but also give rise to problems such as piracy and the use of works without the permission of the copyright owner. This digital piracy can result in economic and moral losses for creators. This study aims to analyze the application of copyright in the context of social media and examine the legal regulations governing copyright protection to address digital piracy in Indonesia. The method used in this study is a normative legal research method with a statutory and conceptual approach. The results show that legal protection for digital works is regulated by Law Number 28 of 2014 concerning Copyright and is strengthened by Law Number 1 of 2024 concerning Electronic Information and Transactions. These two regulations provide a legal basis for protecting the moral and economic rights of creators and authorize the government to block access to content that infringes copyright. These regulations are expected to reduce digital piracy and create a digital ecosystem that respects intellectual property rights.

Teenage pregnancy remains a reproductive health issue in Indonesia, including in Batam City. According to data from the Batam City Health Office in 2024, there were 18 cases of teenage pregnancy (0.06%) with the Lubuk Baja Health Center being one of the highest areas. Pregnant teenagers are at high risk of complications such as anemia, malnutrition, and low birth weight (LBW), which contribute to high rates of maternal and infant morbidity. This study used a descriptive method with a case study approach on Ny. S, an 18-year-old teenager with a pregnancy in the Lubuk Baja Health Center area of Batam City in 2025. Data collection was conducted through interviews, observations, physical examinations, and SOAP documentation following the 7-step Varney obstetric management. The findings revealed that Ny. S experienced mild complaints such as nausea, reduced appetite, and anxiety about her pregnancy. After three visits, the mother's complaints decreased, appetite improved, anxiety decreased, and nutritional status was within normal limits. Comprehensive midwifery care with a biopsychosocial approach was proven effective in improving both the physical and mental health of pregnant teenagers and preventing pregnancy complications.

Digital copyright piracy remains a growing legal issue in Indonesia alongside the rapid development of information technology. This practice not only causes economic losses to creators and copyright holders but also reflects a gap between legal norms and social realities. This study aims to analyze legal protection for digital copyrights and to assess the effectiveness of Law Number 28 of 2014 on Copyright. This research employs a normative legal method using a library research approach by examining statutory regulations and relevant academic literature. The findings indicate that although Indonesia has established an adequate legal framework for copyright protection, its implementation remains ineffective due to low public legal awareness, weak law enforcement, and challenges in monitoring digital platforms. These findings emphasize that effective copyright protection requires not only comprehensive regulations but also synergy between the government, law enforcement authorities, and the development of a strong legal culture within society.
