The increasing demand for housing in tropical regions requires building materials that are fast to apply, environmentally friendly, and resilient to extreme climate conditions as well as disaster risks. Conventional interlocking bricks are often chosen for their ease of construction, yet they still face challenges such as moisture and early cracking. This study proposes the innovation of the Hybrid Living Green Brick, a combination of lightweight bricks made from rice husk ash and fly ash waste (FRCB) with a biological layer of cyanobacteria. FRCB improves compressive strength by approximately 30% with the addition of 5% rice husk ash, achieving 65 kg/cm², thereby meeting Class 50 requirements (≥50 kg/cm²) according to SNI-15-2094-2000. The incorporation of 3% cyanobacteria provides an additional though not significant strength improvement, while still within the Class 50 category. It also reduces brick weight by 4.3%, with further optimization potential through cyanobacteria integration, and lowers carbon emissions from the firing process. Cyanobacteria induce the formation of CaCO₃ layers that seal pores, reduce water absorption by an average of 10%, and provide self-healing properties for microcracks. Preliminary observations indicate that FRCB offers stable mechanical performance, while biological activity was observed on the 7th day with the formation of pale-white mineral layers continuing until the 28th day. This hybrid innovation shows potential to support sustainable and disaster-resilient tropical construction by combining the mechanical strength of waste-based materials with the biological durability of cyanobacteria against extreme climates. Despite challenges related to moisture control and production standardization, the Hybrid Living Green Brick concept opens new pathways for developing environmentally friendly construction materials that are more adaptive to disaster-prone tropical conditions.

Exercise is a planned physical activity that not only contributes to physical fitness but also plays a significant role in maintaining and improving mental health. This study aims to explore the relationship between physical exercise and mental well-being among adolescents and university students with diverse backgrounds of physical activity. The research employs a qualitative approach using in-depth interviews with five informants, consisting of university students who engage in recreational exercise, recreational runners, middle- and long-distance runners, and a sprinter. Data collection was conducted in several public sports spaces in the city of Bandung, focusing on participants’ subjective experiences related to their psychological conditions before and after engaging in exercise. The findings indicate that all participants perceive exercise as an effective means of emotional regulation. Physical activity is consistently associated with improved mood, reduced stress, enhanced sleep quality, stable energy levels, and increased academic concentration and focus. In addition, exercise contributes to the development of self-confidence, self-efficacy, and self-control through structured routines. The social aspects of exercise, such as support from peers, communities, and coaches, were shown to strengthen the sustainability of physical activity while also providing essential emotional support for mental health. However, among competitive athletes, performance-related pressure was identified as a factor that may negatively affect psychological well-being, although this effect can be moderated by adequate social support. Overall, the findings of this study emphasize that exercise functions as an adaptive coping mechanism operating through biological, psychological, and social pathways, and highlight the importance of consistency and balance in physical activity to achieve optimal mental health benefits.  

Financial literacy is an important skill that needs to be introduced from an early age so that children can understand the value of money and manage it wisely. This activity aims to improve basic financial literacy among children at LKSA Santa Anna Bojonegoro through a participatory educational approach.

Objective: Autoimmune diseases are complex disorders that arise when the immune system loses tolerance to self-antigens, leading to chronic inflammation and tissue damage. To understand disease pathogenesis and to evaluate therapeutic efficacy, animal models are widely used in autoimmune research. This review aims to analyze various types of animal models employed in studies of autoimmune diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), type 1 diabetes mellitus (T1DM), and multiple sclerosis (MS), with a particular focus on reproducibility and clinical applicability. Methods: This study was conducted through the selection and analysis of scientific literature published over the last ten years (2015–2025), using specific keywords including “clinical application,” “autoimmunity,” “animal models,” “humanized mice,” “lupus,” “rheumatoid arthritis,” “reproducibility,” and “translational research.” Literature searches were performed in major databases such as Google Scholar, PubMed, ScienceDirect, and Scopus. Results: Spontaneous models, such as NOD and MRL/lpr mice, exhibit close resemblance to human disease pathogenesis but are influenced by strain variability and environmental factors. Induced models, including collagen-induced arthritis (CIA) and experimental autoimmune encephalomyelitis (EAE), allow greater control over disease onset but do not fully capture the clinical complexity observed in humans. Humanized models demonstrate high translational relevance; however, their use is constrained by high costs and technical limitations. Conclusion: No single animal model is universally ideal for studying autoimmune diseases. Model selection should be based on biological relevance, reproducibility of outcomes, and the potential for clinical translation in autoimmune disease research.

The advancement of social media platforms, especially TikTok, has drastically changed the behavioral patterns and lifestyles of Generation Z. One psychological impact of intensive social media use is Fear of Missing Out (FoMO), which is the worry of missing out on news, trends, or viral social activities. This study aims to reveal how FoMO affects the lifestyle of Generation Z active on TikTok, focusing on aspects of mental health, shopping habits, and the balance of social interactions. This research uses a literature study approach with a qualitative descriptive method, through in-depth analysis of 21 scientific articles published between 2019 and 2025. The findings show that FoMO is associated with increased anxiety, depression, personal dissatisfaction, and excessive social media use among Generation Z. Furthermore, FoMO also drives impulsive consumption patterns and purchases triggered by online trends as well as the desire for social approval. On the other hand, internal factors such as self-confidence and self-control ability have proven to reduce the level of FoMO and its negative effects. This study concludes that FoMO is a complex phenomenon that impacts the mental health and lifestyle of Generation Z, thus requiring measures such as increasing digital literacy, strengthening self-control, and using social media wisely to reduce the negative impacts of FoMO in the long term.

Millennials aged 25 to 40 are currently the largest consumer group. Their dynamic lifestyles and social demands make them highly consumptive. The ease of obtaining credit, such as loans and credit cards, through advances in financial technology (FinTech) has further accelerated this trend. Unfortunately, exposure to social media that portrays a consumptive lifestyle encourages many of them to follow trends and buy non-essential items. The lack of financial literacy among young Indonesians often makes them unaware of the consequences of debt, which ultimately erodes the financial independence that is so badly needed in this era. This study aims to prove the relationship between Financial Technology, Lifestyle, and Self-Control that influence Debt Behavior. In addition, it is seen that men and women have different levels of self-control, and this is input for researchers to add gender as a moderating variable in their research. The research method used is a mixed method, more precisely a Sequential Explanatory Design, in which quantitative data is collected and analyzed, then combined with qualitative data to explain or enhance quantitative findings. Primary data was collected through questionnaires and interviews with experts, while secondary data was collected from articles and other reference data. The population used was the community in the city of Jakarta. The sample was collected using accidental sampling techniques, and the statistical test tool used Structural Equation Modeling (SEM) with SmartPLS software.
