Digital images often experience noise disturbances that can reduce visual quality and interfere with the image analysis process. One common type of noise is salt and pepper noise, especially in grayscale images, which is characterized by the random appearance of black and white dots. This study applied the Deep Convolutional Autoencoder (DCAE) method with a skip connection mechanism to eliminate salt and pepper noise in grayscale images measuring 256×256 pixels. The dataset used consists of 300 pairs of clean images and noisy images that have gone through the preprocessing stage, including normalization and data augmentation. The model was trained using an Adam optimizer with a Mean Squared Error (MSE) loss function and validated through a train-test split scheme to avoid overfitting. Model performance was evaluated using Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index (SSIM) metrics. The test results showed that the DCAE model with skip connections was able to effectively reduce noise while maintaining the main structure of the image based on the PSNR and SSIM values obtained, and showed better performance than conventional median filters. In addition, the model was successfully implemented into a Streamlit-based application to perform the image denoising process interactively, making it easier for users to experiment and visualize results in real-time.

The legal relationship between doctors and patients is essentially based on an obligation of effort (inspanningverbintenis), rather than an obligation of result (resultaatverbintenis). In practice, however, dissatisfaction with the outcomes of medical services often leads to criminal reports alleging medical negligence, which implies the criminalization of healthcare professionals. On the other hand, Law Number 17 of 2023 concerning Health and the Regulation of the National Police of the Republic of Indonesia Number 8 of 2021 provide broader opportunities for the application of restorative justice in resolving criminal cases, including medical negligence. This research aims to analyze the criteria for applying restorative justice in medical negligence cases at the investigation level, examine resolution patterns oriented toward recovery and justice for all parties, and identify the obstacles faced by investigators in implementing this mechanism. The research method used is normative legal research with a statutory approach and a conceptual approach, conducted through a review of legislation, legal doctrines, and expert opinions in the fields of health law and criminal law. The results indicate that the application of restorative justice in medical negligence cases can, in principle, be carried out as long as it meets the formal and material requirements as regulated in Police Regulation No. 8 of 2021, and aligns with the restorative resolution paradigm promoted by Law No. 17 of 2023 concerning Health. Resolution patterns oriented toward mediation, reconciliation, and reparation are considered more capable of achieving substantive justice for victims while providing protection for medical personnel who lack mens rea. Nevertheless, the implementation of restorative justice at the investigation level still faces various obstacles, including subjectivity in determining compensation, differing understandings among law enforcement officers regarding the boundary between professional error and criminal offense, disagreement between parties, and the pressure of public opinion and social media. Therefore, it is necessary to strengthen regulations, increase the capacity of investigators, and harmonize understanding among stakeholders to optimize the application of restorative justice in medical negligence cases.

Health behaviors among youth have undergone a significant transformation, shifting from nightlife culture and alcohol consumption toward healthy lifestyles such as community sports (running and padel). This phenomenon, known as the sober curious movement, is triggered by massive interactions in digital spaces. This study aims to analyze the role of social media as a catalyst in the transformation of the sober curious lifestyle and the increased participation of youth in healthy living through a literature review. This research employs a narrative literature review method. Literature searches were conducted through the Consensus database, Google Scholar, and Garuda, covering the period from 2021 to 2026. Data analysis was performed thematically on articles relevant to the digital health behavior of young adults. Findings indicate that social media acts as a primary catalyst through social norm engineering, whereby health is now viewed as a prestigious social status symbol. Digital platforms provide a space for the younger generation to normalise alcohol-free lifestyles, so that they are no longer considered unusual by their peers. The synergy between educational content and online communities accelerates the continuous internalisation of preventive values. Social media effectively shifts the health paradigm of the younger generation from a mere medical obligation to an aspirational digital identity. Public health practitioners need to optimize this digital potential as a proactive health promotion instrument to foster a fitter society in the future.

As HIV transitions into a manageable chronic condition, optimizing lifestyle behaviors is key to achieving long-term health outcomes. This study aims to explore lifestyle behaviors in people with HIV (ODHIV) who participate in peer support groups as well as identify socioeconomic and clinical predictors of healthy lifestyle engagement. The research design was a cross-cutting analysis involving 250 ODHIV registered in a community support group. Lifestyle behavior was measured using  a modified Health-Promoting Lifestyle Profile II (HPLP-II) instrument. Multivariate logistic regression analysis was used to determine independent predictors, with Nagelkerke R² and Hosmer–Lemeshow tests  to assess model suitability. The results showed that 56.2% of respondents had a healthy lifestyle. Factors of higher education (OR = 2.77; p = 0.006), older age (OR = 2.32; p = 0.015), employment status (OR = 2.00; p = 0.029), and longer duration of ART therapy (OR = 1.17 per year; p = 0.003) were significant predictors. The model explains 32% of lifestyle variations, with ART compliance and substance control as the strongest behavioral domains. These findings confirm the role of peer support groups as a behavioural reinforcement environment, but socioeconomic disparities remain influential. The integration of theory-based lifestyle interventions into community-based HIV services is necessary to optimize chronic disease outcomes.

The industrial revolution 4.0 has brought rapid advances in technology, one of which is artificial intelligence (AI). AI has the ability to imitate the human thought and action process in solving various problems. However, the implementation of AI raises legal problems related to responsibility for the negative impacts caused, such as cybercrime, information manipulation, privacy violations, and misuse of technology. Indonesia, as a country based on law, is faced with the challenge of regulating AI to be in line with technological developments. Currently, legal regulations in Indonesia do not specifically regulate the legal responsibility of AI. Positive laws, such as the Civil Code and the ITE Law, can be used interpretively, but are not enough to address the complexity of AI. Legal responsibility related to AI is debatable, whether it is imposed on the developer, owner, or user of AI. In addition, AI does not have a “mens rea” in criminal law, so that unlawful acts are more relevant to be imposed on the responsible human. To overcome this problem, legal reform or the creation of special regulations that comprehensively regulate AI are needed. These regulations must include privacy protection, data security, and criminal and civil liability due to the use of AI. With a clear legal framework, the risk of AI misuse can be minimized and its use can be optimized for the welfare of society.

Coffee husk is an agro-industrial waste with significant potential to be utilized as a renewable energy source through the fast pyrolysis process. This study aims to analyze and optimize gas production from the fast pyrolysis of coffee husk biomass using a screw reactor through single-particle-based Computational Fluid Dynamics (CFD) simulations. The simulations were conducted by varying the operating temperature at 500°C, 600°C, and 700°C to examine pressure distribution, heat transfer, particle temperature, and the formation of pyrolysis products, namely bio-oil, biogas, and biochar. The modeling was performed using COMSOL Multiphysics 6.2 with a numerical approach to represent thermal phenomena and biomass decomposition reactions during the pyrolysis process. The simulation results indicate that increasing temperature significantly affects the rate of heat transfer and the temperature distribution of coffee husk particles. At 600°C, heat transfer and temperature distribution are more uniform compared to 500°C, although heating at the particle core is not yet fully optimal. The pressure distribution shows a stable flow of pyrolysis gas from the bottom to the top of the reactor. In terms of products, increasing temperature leads to a reduction in biochar and bio-oil formation due to the occurrence of secondary reactions, while biogas production increases. The highest gas production is achieved at 700°C, indicating the most optimal condition for maximizing gas yield from fast pyrolysis. Therefore, single-particle-based CFD simulation can be used as an effective tool to understand pyrolysis mechanisms and optimize process parameters in a screw reactor.

Community service with the theme of Socialization and Education of Legal Products for MSME and Creative Economy Actors in Temberan Village, Pangkalpinang City, is based on field conditions, where many MSME actors in the region do not have legal legality for the businesses they run and lack basic knowledge regarding product packaging and brand creation that have high marketability. As a result, their businesses are not developing to strengthen the creative economy and enhance the capacity of actors. The model used in this program is a direct dialogue method with the MSME actors. The discussion results showed that of the 26 participants, only 1 MSME actor had received guidance and had an NIB (Business Identification Number), but lacked a halal certificate and patent rights for their product brands. The other 25 participants were briefed for the first time regarding the importance of legal legitimacy for their business. Therefore, it can be concluded that these 25 MSME actors do not have legal legitimacy for their businesses. The team provided assistance to help register their businesses by collaborating with relevant agencies. Regarding product branding, it was found that all participants had not optimized their product branding, as most MSME actors in Temberan Village packaged their products simply without attractive branding, packaging, colors, or packaging materials. Many even used plastic wrapping without a brand. The team intervened intensively by providing further assistance to MSME actors in Temberan Village, utilizing information and communication technology to help determine product brands for those without one and to select packaging materials that follow current trends, shapes, colors, and materials to make the product more attractive and increase branding and consumer interest.

Internal governance and psychological safety are key factors influencing employee performance in private universities in Indonesia. Internal governance ensures efficient and transparent operations aligned with institutional goals, whereas psychological safety allows employees to express ideas and take risks without fear of negative consequences. Organizational communication mediates the relationship between these factors and employee performance. This study aimed to assess the impact of internal governance and psychological safety on employee performance in private universities in Banten, with organizational communication as an intervening variable. This study explores how these elements contribute to performance through effective communication. A quantitative approach was employed with a sample of 50 respondents from private universities in Banten. Data were collected via structured surveys, and SmartPLS 4.0 software was used to analyze the relationships between internal governance, psychological safety, organizational communication, and employee performance. This study found that internal governance positively influenced organizational communication, which significantly enhanced employee performance. Psychological safety also contributes to organizational communication but has a minimal direct impact on performance. Organizational communication plays a crucial mediating role in linking governance, safety, and performance. These findings emphasize the importance of strengthening internal governance, fostering psychological safety, and improving organizational communication to optimize employee performance in private universities. By focusing on these factors, universities can create a more supportive environment that enhances employee engagement and effectiveness of the faculty.

Background: The postpartum period is a critical phase requiring optimal nutritional intake for maternal recovery and ensuring the quality of breast milk. In densely populated urban areas such as Semampir District, dietary quality is often influenced by the level of nutrition knowledge and household economic conditions. Objective: This study aims to analyze the relationship between nutrition knowledge and household food security with dietary quality among postpartum mothers in Semampir District, Surabaya. Methods: This was an observational analytical study with a cross-sectional design. A total of 340 postpartum mothers were selected using simple random sampling. Nutrition knowledge was measured through a structured questionnaire, food security was assessed using the Household Food Insecurity Access Scale (HFIAS), and dietary quality was measured using the 3-level Balanced Diet Index derived from 24-hour food recall data. Data were analyzed descriptively and through the Chi-Square correlation test. Results: The findings indicated that the majority of respondents possessed a good level of nutrition knowledge (average correct answers >75%), with the highest score in anemia prevention (81.2%) and the lowest in the functional role of Vitamin A (75.9%). Dietary quality assessment revealed that most respondents were in the [Select: Moderate/Poor] category based on IGS scores. Bivariate analysis showed a significant relationship (p < 0.05) between both nutrition knowledge and household food security with the dietary quality of postpartum mothers. Conclusion: Good nutrition knowledge and stable food security contribute positively to the dietary quality of postpartum mothers. Targeted nutritional education regarding micronutrients and strengthening food access at the household level are essential to optimize maternal health during the postpartum period in urban settings.

This systematic literature review examines the implementation of Content and Language Integrated Learning (CLIL) in Indonesian senior high schools. Following PRISMA guidelines, nine studies published between 2021 and 2025 were analyzed to identify the benefits and challenges of this approach. The findings reveal that CLIL effectively enhances student engagement, motivation, and the integrated development of subject knowledge and English proficiency. However, implementation is often hindered by limited teacher readiness, insufficient collaboration between subject and language teachers, and a lack of appropriate assessment methods. Analysis using the 4Cs Framework shows that while Content and Communication are prioritized, Cognition and Culture receive less explicit attention. The study implies that successful CLIL sustainability requires continuous professional development and stronger institutional support within the Merdeka Curriculum. These results provide a strategic basis for educators and policymakers to optimize bilingual instruction in Indonesia.

MSMEs Traditional culinary MSMEs play a vital role in the Indonesian economy through job creation, income equality, and preservation of local culture. However, limited capital, raw materials, and labor, as well as unsystematic production planning, mean that MSME production decisions are still intuitive, leading to inefficiencies and suboptimal profits. A case study of MSME Sostang Tijang Bruno, a Sundanese cireng producer, shows that cireng production is still based on experience without clear calculations, resulting in a mismatch between production and demand and waste of raw materials. This study aims to optimize cireng production volume using the Graphical Linier Programming method to maximize profits by considering constraints on raw materials, working time, and market capacity. Data were obtained through observation, interviews, and documentation. The decision variables were the production volume of original chicken-filled cireng and spicy chicken-filled cireng. The analysis results showed an optimal production combination of 2.93 kg of original chicken-filled cireng and 0.53 kg of spicy chicken-filled cireng with a maximum profit of Rp499,000 per day. This method is expected to help MSMEs make more efficient and rational production decisions
