Deep learning is a learning approach that emphasizes in-depth understanding of concepts and the development of critical, creative, collaborative, and communicative thinking skills. Although this approach aligns with the demands of a competency-based curriculum, its implementation at the elementary school level still faces various challenges. Based on a preliminary survey, 65% of elementary school teachers in partner schools admitted to experiencing difficulties in implementing deep learning effectively in the classroom. This study aims to identify innovative strategies that can improve teacher competency through a structured training program. The training activities involved 120 teachers from 10 elementary schools who are members of the teacher working group (KKG), with a focus on mastery of deep learning concepts, the application of interactive learning methods, and the use of educational technology. The training method was implemented continuously using a blended learning approach, including face-to-face sessions, practical workshops, mentoring, and the use of digital learning platforms. Evaluation results showed that 80% of training participants experienced significant improvements in their understanding of deep learning concepts, 70% were able to integrate interactive learning strategies into the teaching process, and 60% actively utilized learning technology to enrich students' learning experiences. These findings confirm that ongoing training integrated with technology support can improve teachers' capacity to implement deep learning in the classroom. Furthermore, the program's success is also influenced by intensive mentoring and collaboration among teachers through the Teacher Working Group (KKG). The implications of this research point to the need for educational policies at the elementary school level that encourage systematic, sustainable, and technology-based teacher professional development programs. Thus, the implementation of deep learning can be optimized to support the achievement of competency-based curriculum objectives and improve the overall quality of education

This study aims to analyze the performance of the Hospital Management Information System SIMRS in the pharmacy unit of RSU Fitri Candra Wonogiri using the HOTFIT model approach.

The Geothermal Power Plant (PLTP) project in Batukuwung Village, Padarincang District, Serang Regency, has raised concerns among the community about the threat of environmental damage and disruption of the sustainability of the local agricultural system. So far, the community has depended on traditional agriculture that is closely tied to local social, cultural, and ecological values. PLTP projects, which are framed as part of the clean energy transition, actually create tensions between development and environmental conservation. This research aims to examine the social and ecological impact of the PLTP project on the lives of the village community. The method used is a qualitative approach with case studies. Data were collected through purposive sampling techniques for in-depth interviews with affected residents, community leaders, and environmental activists, as well as analysis of online media content and policy documents. The results of the study show that the presence of the project has created ecological and social vulnerability. Disruption to access to clean water, degradation of soil quality, and disruption of agricultural ecosystems are serious threats. In addition, the space for public participation in the project-related decision-making process is very limited, thus triggering resistance and horizontal conflicts. These findings show that the clean energy narrative does not always align with the reality on the ground. Therefore, it is important to consider the principles of ecological justice and the sovereignty of local communities in any energy development policy. This study recommends participatory dialogue and a thorough environmental evaluation before the project proceeds, so that development does not compromise the right of life of local communities and the ecological sustainability of the region. The active involvement of citizens as subjects, not objects of development, is the key to creating sustainable and equitable solutions for all affected parties.

The number of school-age adolescent girls in Banggai Regency, Central Sulawesi, still faces serious challenges related to nutritional problems such as anemia and chronic energy deficiency (SEZ). Low nutritional literacy and unbalanced food consumption habits also worsen their nutritional status, especially during puberty when nutritional needs increase significantly. This service activity aims to increase the understanding and awareness of young women on the principles of balanced nutrition through a participatory educational approach. The implementation of the activity was carried out at SMP Negeri 2 Bunta, Simpang Raya District, involving 30 students in grades VII and VIII as well as UKS supervisory teachers. The intervention included providing material on "Fill My Plate", the 4 pillars of balanced nutrition, and the risk of nutritional disorders in adolescents. The material was delivered in the form of interactive counseling using leaflet media, accompanied by knowledge measurement through pre-test, post-test, and one-week post-activity evaluation. The results of the activity showed a significant increase in students' understanding of the principles of balanced nutrition, with the knowledge score of the good category increasing from 40% to 87%. Most of the participants were able to mention the composition of the meal portion, the importance of breakfast, restrictions on fast food consumption, and the need to drink enough water every day. This activity also has an impact on increasing the capacity of teachers in assisting and monitoring the health status of students through the UKS program. Teachers become more active in conducting periodic counseling and recording the nutritional development of female students on a regular basis. School-based balanced nutrition counseling has been proven to be effective in improving adolescent nutritional literacy. This educational model can be replicated in other regions with cross-sectoral support such as education offices, health centers, and village governments, to support the achievement of sustainable development goals in the health sector.

The application of the MOORA (Multi-Objective Optimization on the basis of Ratio Analysis) method in employee promotion decisions at PTPN 4 aims to enhance efficiency and objectivity in decision-making. This method allows managers to evaluate employees based on multiple criteria simultaneously, such as performance, experience, contributions, and other relevant factors. By considering these various aspects, MOORA helps make promotion decisions more transparent and fair. One of the primary advantages of applying the MOORA method is its ability to reduce bias that may occur during the promotion process. Bias can arise from subjectivity or imbalance in employee assessments, which are often based on individual judgments or personal perceptions. By using MOORA, promotion decisions are based on more objective and measurable data, making the process more systematic and structured. The MOORA method can also increase employee motivation. A transparent promotion process based on clear criteria provides employees with a strong incentive to continuously improve their performance. When employees know that promotions are based on fair evaluation, they are more motivated to work harder. This, in turn, will increase overall productivity and performance at PTPN 4. The implementation of MOORA at PTPN 4 also provides advantages in better human resource management. With the MOORA-based decision support system, managers can easily identify employees who have the best potential for promotion. This process involves several steps, such as data normalization, determining criteria weights, and calculating final values that reflect overall employee performance. The end result is the selection of employees who meet the qualifications and have outstanding performance for promotion, supporting the sustainable development of the organization.

Arginine deiminase (ADI) is a promising enzyme with significant therapeutic potential, particularly for its anticancer effects through the depletion of arginine in cancer cells that are auxotrophs. In this study, we aimed to optimize the production of ADI using clinical Escherichia coli isolates and to evaluate its antioxidant activity. A total of 25 E. coli isolates were obtained from 45 hospital samples collected in Wasit Province, Iraq. Optimization of ADI production was performed by systematically testing various factors including culture media, pH, carbon and nitrogen sources, incubation temperature, and time. The antioxidant activity was assessed using the DPPH radical scavenging assay. The highest ADI production was achieved using a modified M9 medium supplemented with 1% w/v sucrose as the carbon source and 5% w/v yeast extract as the nitrogen source. The optimal enzyme activity of 1.6 U/mg protein was observed at pH 7.0, 37°C, and after 24 hours of incubation. The crude ADI extract exhibited high antioxidant activity, with 79.28 ± 1.06% DPPH scavenging at 200 µg/mL, comparable to ascorbic acid, which showed 86.11 ± 1.45% DPPH scavenging. The study successfully optimized the conditions for enhanced ADI production based on clinical E. coli isolates, demonstrating its potential as both an anticancer enzyme and an antioxidant. The dual therapeutic potential of ADI warrants further research, including clinical trials, to explore its application in cancer therapy and as an antioxidant in medical treatments, offering promising avenues for future drug development and improved therapeutic strategies, particularly for targeting cancer and oxidative stress-related diseases.

Divorce has a significant impact on a child's psychological and social development, particularly in the aspect of determining custody rights, which should prioritize the principle of the child's best interests. This study aims to analyze the balance between Islamic legal norms as stipulated in the Compilation of Islamic Law (KHI) and positive law in Indonesia, in cases where children under the age of 12 express a desire to live with their father after the divorce. The research approach used is a juridical-normative with a qualitative analysis method that focuses on a literature review of laws and regulations such as the KHI, the Marriage Law, the Child Protection Law, and the Convention on the Rights of the Child, as well as relevant legal and jurisprudential literature. The results of the study indicate that although normatively the KHI prioritizes the mother as the caregiver of children under 12 years old, there is room for flexibility that allows the court to consider the child's wishes if it better ensures the child's welfare and safety. This approach is supported by the principle of maslahah mursalah in Islamic law, which allows adjustments for the benefit of the child. The main challenges in its implementation include the minimal involvement of professionals such as child psychologists in the evaluation process, the existence of gender stereotypes that influence judges' decisions, and emotional conflicts between parents that often override the interests of the child. Therefore, this study recommends that judicial institutions actively involve psychologists and mediators in custody proceedings, improve training for judges in understanding the psychosocial dynamics of children, and update legal guidelines so that children's wishes can be assessed objectively. Furthermore, education to the wider public about the importance of gender non-discrimination in child care is also needed so that custody decisions truly reflect the principles of comprehensive child protection and welfare.

Self-evaluation is an important instrument in teacher professional development, as it can help identify strengths and weaknesses in learning practices.

This study examines social ecology from the perspective of hadith science (‘ulum al-hadith), with the aim of exploring the environmental and social values contained in prophetic hadiths. The main focus of this study is the methodological analysis of hadiths related to ecological issues, such as environmental conservation, social justice, and natural resource management. This study uses a hadith criticism approach, namely by examining aspects of authenticity through analysis of sanad (chain of narrators), criticism of matan (the content of the hadith), and contextual and semantic interpretation of hadiths relevant to environmental themes. In this study, the hadiths analyzed were selectively selected based on their relevance to the principles of Islamic social ecology. The analysis process was carried out thoroughly to assess the validity of the hadith and understand its meaning and normative objectives. This approach integrates classical evaluation methods of hadith science with a contemporary ethical perspective, resulting in a comprehensive framework for formulating hadith-based environmental ethics. Research findings indicate that many authentic hadiths contain strong social ecological principles, such as the concept of caliphate (human leadership over the earth), mizan (balance), and distributive justice. These values emphasize the importance of human responsibility in preserving nature and creating harmony between humans and their environment. These hadiths also demonstrate the close relationship between the spiritual dimension and socio-ecological responsibility. This study makes a significant contribution to the development of hadith-based Islamic environmental jurisprudence. With a methodological and academic approach, this study enriches understanding of Islamic ecological ethics and opens up opportunities for integrating religious values into just and sustainable environmental management.
