Silver nanoparticles (AgNPs) exhibit strong antimicrobial properties against plant pathogens. However, studies on the application of AgNPs, synthesized using the fungus Trichoderma harzianum, to control the growth of Ganoderma boninense Pat, which causes basal stem rot (BSR) in oil palm (Elaeis guineensis Jacq.), have not been reported. Therefore, this study aimed to assess the potential of AgNPs, biologically synthesized using T. harzianum, as a biofungicide and evaluate their effect on the growth of G. boninense in vitro and in vivo. Secondary metabolite compounds were identified using Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GC-MS), and the presence of AgNPs was confirmed by a brown color change, followed by UV-Vis spectroscopy, particle size analysis, and in vitro testing. The FTIR and GC-MS results showed that isothiocyanate (N=C=S) and n-hexadecanoic acid (20.51%) were present as the antifungal compounds. The AgNPs synthesized using T. harzianum were detected at approximately 410 nm and had a nanoparticle size of 77.3 nm. In vitro application of the AgNPs at a concentration of 100 mg·liter-1 exerted a significant inhibitory effect on the growth of G. boninense. This result was consistent with the findings on palm oil seedlings. The AgNPs-Th can suppress the severity of BSR disease and can stimulate the vegetative growth of oil palm plants. In conclusion, this study expanded the current understanding of antifungal effects of AgNPs synthesized using T. harzianum and revealed their potential to suppress BSR caused by G. boninense in oil palm plantations.

This research aims to analyze the implementation of the Protection and Rehabilitation Service Program for Juvenile Delinquents in Surabaya City, conducted by the Social Service of East Java Province. Juvenile delinquency remains a significant social problem requiring comprehensive intervention through protection and rehabilitation approaches rather than punitive measures. Drawing on George C. Edward III's policy implementation theory, this study examines four critical factors: communication, resources, disposition, and bureaucratic structure. This qualitative research employs a descriptive approach, with data collected through in-depth interviews, observation, and documentation at the Social Service of East Java Province during June-August 2025. Informants include program managers, social workers, psychologists, beneficiaries of the juvenile delinquency program, and their families. The results indicate that the program has successfully served 1,247 juvenile delinquents through integrated services, including psychological counseling, skills training, family therapy, and social reintegration support. The communication dimension shows effective coordination between provincial and city-level agencies, though information dissemination to communities needs improvement. Resource adequacy is generally sufficient with 35 certified social workers, adequate facilities, and an annual budget of Rp 3.2 billion. The disposition of implementers demonstrates a strong commitment to child-centered approaches. Clear SOPs and inter-agency collaboration protocols support the bureaucratic structure. The program achieves 72% successful rehabilitation rate with 68% of beneficiaries returning to formal education or productive activities. Challenges remain in stigma reduction, family involvement, and post-rehabilitation monitoring. This study recommends strengthening community-based prevention, expanding vocational training options, developing peer support networks, and establishing sustainable aftercare mechanisms.

Stunting remains a major nutritional problem affecting the quality of human resources in Indonesia, including in Madegondo Village, Sukoharjo. Although local food resources such as catfish, tempeh, moringa, and cassava are abundant, they have not been optimally utilized for family nutrition. The Smart Nutrition Kitchen program was designed to empower communities through nutrition education, training in local food processing, the establishment of a community nutrition kitchen, and strengthening fathers’ roles in household food security. The implementation methods included counseling, training, hands-on practice, mentoring, and continuous evaluation involving posyandu cadres, mothers, and fathers of under-five children. The results showed a significant improvement in nutrition knowledge among cadres (from 48% to 97%) and mothers (from 31% to 82%) after the intervention. In practice, 70% of mothers successfully applied innovative local food recipes, while 30% adapted them to family preferences. Fathers’ participation also increased, with 70% of families starting home food security practices through hydroponics, polybag gardening, or catfish farming. This program has proven effective in improving knowledge, skills, and family involvement in utilizing local food, while also creating economic opportunities through local food-based products. Therefore, the Smart Nutrition Kitchen has the potential to serve as a sustainable model for stunting prevention based on household food self-reliance.

This study uses the BSDS500 dataset, which consists of 500 natural images with different textures and illuminating conditions and then applied different image compression techniques such as Autoencoder, LZMA, JPEG, and JPEG2000. To compare these methods, we use performance metrics such as Mean Squared Error (MSE), Peak Signal-to-Noise Ratio (PSNR), Structural Similarity Index (SSIM), Compression Ratio (CR), Compression Factor (CF), Bits per Pixel (BPP), and Space Savings (SSs%). The study shows that JPEG2000 outputs the best image quality in terms of MSE, PSNR, and SSIM, while JPEG is the most efficient method, as it saves the most space in compressing the image. The Autoencoder, which is based on deep learning, can handle complex images, but its high computing cost and long training time make it less suitable for everyday image compression tasks.

Nutritional imbalances caused by modern lifestyles and limited awareness of healthy eating remain widespread issues requiring technology-driven solutions. This study aims to design and evaluate a mobile application prototype, NutriWise, that provides daily meal recommendations tailored to users' nutritional needs and preferences. A User-Centered Design (UCD) approach was employed, involving users throughout the stages of requirement analysis, interface design, and initial prototype evaluation. The results indicate that the application is easy to use, delivers relevant meal suggestions, and supports nutritional monitoring through food logging and visual tracking features. These findings are supported by previous studies emphasizing the effectiveness of personalization and user-centered approaches. The study offers practical contributions to the development of adaptive digital solutions for daily nutrition management

Objective Suicidality is a critical public health concern, especially among emerging adults who have experienced trauma. However, limitations remain in understanding the associations of suicidal risk and stress-responding. The current study experimentally evaluated the extent to which suicidal thoughts and behaviors (lifetime ideation/attempts, past-year suicidal ideation, threat of suicide attempt, likelihood of suicide in the future) were associated with self-reported psychological and physiological reactivity to a trauma-relevant stress induction task via breathing tasks. Method The sample comprised 94 trauma-exposed undergraduate students (M age = 20.30; 61.7% women) who completed a laboratory-based, within-subjects study. Participants completed both a voluntary hyperventilation challenge and a normal breathing control task and reported psychological and physiological reactivity before and after each trauma-relevant stress induction task. Results An overall path model indicated past-year suicidal ideation was significantly positively associated with psychological reactivity (β = .51); no other associations were significant. Conclusions Identifying patterns between stress-responding and suicidal thoughts and behaviors may allow researchers and clinicians to develop programs to reduce the risk of suicide in young adults in the future, especially among those who are trauma-exposed.

This study explores the role of Strategic IT Planning (SITP) in fostering Sustainable Competitive Advantage (SCA) among firms operating in emerging economies. With the rapid pace of digital transformation reshaping global competition, aligning IT strategy with business goals has become critical. Drawing on a combination of primary and secondary datasets, the research examines the impact of SITP maturity on firm performance, the mediating influence of digital capabilities, and the moderating role of national digital readiness. The methodology includes firm level survey data integrated with national indicators across multiple emerging markets. Hierarchical Linear Modeling (HLM) is employed to analyze multi level panel data, capturing the nested relationships between organizational practices and country level digital infrastructure. The study applies Structural Equation Modeling (SEM) to validate the effects of SITP on SCA through digital capabilities. Results indicate that higher levels of SITP maturity significantly correlate with improved firm performance and long term competitive positioning. Digital capabilities such as ERP, CRM, and analytics mediate this relationship by enhancing business alignment and operational coherence. Furthermore, the National Readiness Index (NRI) and digital infrastructure metrics moderate the effectiveness of SITP, with distinct cutoff points observed across countries. The findings underscore the importance of aligning internal IT governance structures with external digital environments. Policymakers are encouraged to support firms through investments in infrastructure, cybersecurity, and workforce development. Meanwhile, firms are advised to adopt flexible, data driven strategic planning practices.

This research analyzes the administrative systems in Indonesia, Malaysia, and Vietnam, focusing on decentralization, regional autonomy, good governance, public service, accountability, transparency, efficiency, and effectiveness. These three countries have different approaches to managing public administration, influenced by their respective political systems, history, and socio-economic conditions. In Indonesia, decentralization and regional autonomy are prominent because of the strengthening of the role of local governments, although challenges in terms of accountability and coordination between levels of government still exist. With its federal system, Malaysia shows a high efficiency level in administration but faces issues of transparency and public participation. Meanwhile, Vietnam, as a socialist country, centralized administration in the central government, but started to reform to improve efficiency and accountability. This study found that the success of public administration reforms in the three countries depends on applying good governance principles, including strengthening accountability, transparency, and efficiency of the administrative system. The study makes an important contribution to developing public administration systems in developing countries to achieve effective governance that is responsive to the needs of the people. Although the three countries have made progress in some sectors, the main challenges still revolve around improving transparency, strengthening accountability, and managing resources efficiently
