This study aims to explore the factors influencing individuals’ intention to use digital banking services and investigate the role of Resonance FOMO (Fear of Missing Out) in moderating the relationship between intention and actual usage behavior in Indonesia. Quantitative methodologies are implemented in the investigation, utilizing Structural Equation Modeling with WarpPLS for data analysis. A survey was conducted with 380 respondents in Indonesia using a Likert-scale questionnaire to measure various variables, including Effort Expectancy, Hedonic Motivation, Facilitating Conditions, Price Value, Performance Expectancy, and Perceived Risk. The results indicate that Effort Expectancy, Performance Expectancy, Price Value, and Perceived Risk significantly impact users’ intention to use digital banking services, while Facilitating Conditions and Hedonic Motivation did not have a significant influence. Furthermore, the study reveals that Intention to Use strongly affects actual Use Behavior, with Resonance FOMO acting as a positive moderator, the relationship between intention and behavior is improved. The results offer significant understanding of the psychological and environmental elements influencing digital banking adoption in emerging markets. These results offer practical implications for digital banking providers and policymakers seeking to increase user acceptance and engagement by addressing these key influencing factors.
Ambonese banana stem extract (Musa paradisiaca var. sapientum (L.) Kuntze) has been proven to contain the active compound Hexadecanoic acid (Hexa) which can suppress the growth of cancer cells through the apoptosis process. The aims to determine HA interaction to nuclear factor-kappa-B p65/RELA and tumor suppressor-p53 for the development of oral anticancer drugs through molecular docking. In silico molecular docking study carried out include prediction of activity spectra of substances (PASS), drug-likeness analysis based on the lipinski rule of five principles, absorption, distribution, metabolism, excretion, and toxicity (ADMET) study, molecular docking and Hexa bond visualization (CID: 985), along with the positive control comparison 5-fluorouracil (Fluo) (CID: 3385) and the derivative compound 9-octadecenoic acid (Octa) (CID: 445639) which bind to the proteins target RELA (PDB ID: 6NV2) and p53 (PDB ID: 2OCJ). The Hexa, Fluo and Octa compounds' tests were negative for AMES toxicity, indicating that these compounds do not cause genetic mutations. The acute oral toxicity tests yielded values of 1.44 mol/kg for Hexa, 1.939 mol/kg for Fluo and 1.417 mol/kg for Octa. Molecular docking results and bond visualization indicate that the affinity of 9-octadecenoic acid interacts better with RELA and p53 compared to the positive control, i.e. 5-fluorouracil. Hexa compound exhibits a superior binding pocket compared to Fluo and Octa, particularly against the p53 target protein. Hexadecanoic acid compound in Musa paradisiaca var. sapientum (L.) Kuntze represents a breakthrough in developing a new anticancer potential and effectiveness against RELA and p53.
Background While there is an urgent need worldwide to establish methods that prevent diabetic foot ulcers, the effectiveness of a prevention protocol using thermography has been reported. As the number of diabetic patients in Indonesia is increasing, an online program for wound care specialists was developed to disseminate this protocol. The present study evaluated the impact of an online program on wound care specialists' knowledge of diabetic foot ulcer prevention using thermography. Methods This single-group quasi-experimental study was conducted in cooperation with the Indonesian Wound Enterostomal Continence Nurses Association with regard to curriculum and content design, and the evaluation methods of online education for thermography-based diabetic foot ulcer prevention using the learning management system. A questionnaire with 50 multiple-choice questions previously validated for content and readability on the knowledge of diabetic foot ulcer prevention using thermography was used for training evaluations. Results Of 106 Indonesian wound care specialists evaluated, the paired t-test revealed a significant difference between the before and after training questionnaire scores on knowledge (52.0 ± 10.3, 85.2 ± 10.6, respectively, p < 0.001). Repeated measures analysis of variance revealed interactions between time (before and after training) and gender, and between time and type of certificate ( p = 0.046, p = 0.014, respectively). Conclusions An asynchronous e-learning program is an effective method to increase wound care specialists' knowledge of diabetic foot ulcer prevention. These findings suggest that online educational interventions are effective and can be tailored to meet the needs of healthcare professionals, thereby ultimately contributing to better patient care outcomes in preventing DFUs.
Background: WHO recommends the practice of early initiation and exclusive breastfeeding for the first 6 months of life followed by breastfeeding with complementary foods up to 2 years of age. However, currently, the global prevalence of breastfeeding in infants less than 6 months of age is under 50%. Objective: This study aims to predict the factors associated with breastfeeding self-efficacy in RSUD IA Moeis. Methods: A cross-sectional study with multiple logistic regression tests were used to analyze 56 postpartum women. Key variables analyzed included breastfeeding experience and observation of others, adjusted for occupation, education, verbal persuasion, and physical-emotional conditions. Result: Variables associated with Breastfeeding Self Efficacy (BSE) were breastfeeding experience (p-value 0.023) and observation of others (p-value 0.002) adjusted by occupation, latest education, verbal persuasion, and physical emotional conditions. The most dominant variable is the observation of others with Odds Ratio = 61.107 (95% CI OR = 5.478- 711.504). Conclusion: Observation of others is the strongest predictor of breastfeeding self-efficacy among postpartum mothers at RSUD IA Moeis. Mothers who observed others successfully breastfeeding were 61 times more likely to have high BSE than those who did not. Keyword: Breastfeeding self-efficacy, breastfeeding experience, postpartum, sociodemographic.
Breast cancer is one of the leading causes of mortality among women worldwide, prompting the exploration of alternative, natural therapies. This study examines the anti-breast cancer potential of traditional herbal plants used by the Dayak tribe, particularly Kleinhovia hospita Linn. Through in silico approaches, the study investigates the cytotoxic effects and binding affinities of key compounds, such as Scopoletin, Quercetin, and Eleutherol, with breast cancer-related proteins. Molecular docking analysis demonstrated that Quercetin and Eleutherol exhibit high binding affinities (−9 and −8 kcal/mol, respectively) with target proteins, indicating significant potential for inhibiting cancer cell proliferation by targeting proteins like EGFR, JNK, and NUDT5. The drug-likeness analysis confirmed that Quercetin and Eleutherol meet criteria for further therapeutic exploration. These findings suggest that compounds from Dayak tribal plants could be viable anti-cancer agents, providing a scientific foundation for developing culturally relevant and effective treatments for breast cancer. Further research is recommended to isolate and evaluate the bioactive compounds in preclinical and clinical settings. This work supports the potential of traditional Dayak herbal medicine as a natural therapeutic strategy against breast cancer.

Background The use of fat grafting has expanded to include cell and tissue regeneration, necessitating investigations to ensure the viability of stromal and adipose-derived mesenchymal stem cells (ASCs) within the transferred fat parcels. This study explored the impact of harvesting technique and centrifugation on the viability of stromal cells and ASCs in lipoaspirate. Methods Fat was harvested from patients undergoing fat grafting using 2 types of liposuction cannula: (A) a 3-mm blunt tip cannula with 3 smooth holes and (B) a 2.4-mm, sharp point port, multihole blunt tip cannula. Fat from cannula B underwent different processing methods: no centrifugation, 300 g , 600 g , and 900 g centrifugation. Stromal cells were isolated, quantified, and evaluated for viability. ASCs were cultured from these samples to confirm survival. Results Lipoaspirates from 21 patients were analyzed. The mean stromal cell counts were 0.937 × 10 ⁹ ± 0.346 × 10 ⁹ /mL for cannula A and 0.734 × 10 ⁹ ± 0.266 × 10 ⁹ /mL for cannula B ( P = 0.684), with viabilities of 98.79% and 98.22% ( P = 0.631), respectively. ASCs isolated and after 2-passage culture were also higher for cannula A. Stromal cell quantification and viability were lowest in the noncentrifuged group ( P < 0.05) and highest in the 600 g centrifugation group. Conclusions Fat harvesting using cannulas A and B showed no significant difference in stromal cell yield or viability. Handheld syringe liposuction preserved stromal vascular fraction cell and ASC viability. Centrifugation at different speeds did not significantly affect stromal cell viability.

Introduction: Presently, the development of effective vaccines against SARS-CoV-2 is absolutely necessary, especially regarding the emerging of new variants that cause increasing fatalities. Methods: In the present study we designed a mosaic vaccine targeting the mutational spike protein of coronavirus disease 2019 (COVID-19) using a bioinformatics approach. Various immunoinformatics tools were utilized to provide the highest potential for a mosaic vaccine that could activate immune responses against COVID-19. Results: The evaluation of the constructed vaccine revealed that it is antigenic and immunogenic as well as nonallergenic. The physicochemical properties also show promising characteristics, including being highly stable and hydrophilic. As expected, the vaccine shows strong interactions with several important receptors including angiotensin-converting enzyme (ACE)2, Toll-like receptor (TLR)3 and TLR8 by the lowest energy level, docking score and binding free energy. The vaccine binds to receptors via certain amino acids using various types of binding including salt bridges, hydrogen bonds and other means. As shown in computationally derived models, the interactions promote activation of the immune response by eliciting the release of various cytokines, antibodies, memory B and T cells, as well as increasing of natural killer cell and dendrite cell counts. Conclusion: Therefore, the novel designed mosaic vaccine could be considered as a potential vaccine candidate for immediate production to stem the continuing and tragic effects of the COVID-19 pandemic. However, several advanced experimental studies should be conducted to ensure and verify the effectivity and safety against SARS‑CoV‑2 in vivo.
This study responds to concerns about under-five nutrition in Indonesia, especially the levels of stunting, overweight, underweight and wasting recorded in the Indonesia Nutrition Status Survey 2022. In an effort to address these issues and for continued monitoring after toddlers pass the Kartu Menuju Sehat (KMS) at the age of more than 5 years, this study developed the "Gizi SD" application. This application is specifically designed to monitor the health and nutrition of school-age children. The application development process went through Focus Group Discussion (FGD) and prototype testing, which showed good responsiveness to user needs. The app has 5 main menus in nutrition monitoring, successfully integrating the roles of parents, schools, and health centers. Through qualitative and quantitative testing, the app has succeeded in functionality, security, and performance, with prototype evaluation results showing optimal functionality and performance. A satisfactory level of accuracy and a positive level of feasibility were met. The calculation of Body Mass Index for age (BMI/U) in the app is close to the manual calculation with a conformity rate of 0.76%, superior to the WHO AnthroPlus app. Positive user acceptance marks the maturity and readiness of the app for the next step, making it a potential solution in the prevention of nutritional problems in school-aged children in Indonesia.
The discrepancy between students’ preferences and teacher practices for feedback on writing has created difficulty on the side of teachers and confusion on the side of the students. What teachers believe and practice as effective feedback for students may not be the one that students perceive as useful and effective feedback for them. This paper investigates the types of written feedback preferred by the students and the types of feedback provided by the teachers on students’ writing. This study employed a survey design which involved 54 students and 22 teachers using convenience sampling technique. The instrument used in collecting data was a questionnaire in the form of Feedback Scale. The results showed that there were some points of compatibility between students’ preferences and teachers’ practices and some other points were incompatible. The data showed that both students and teachers preferred to have or to give direct feedback but the data also indicated that students liked to have more direct feedback than the teacher could provide. It was also found that the teachers provided more indirect feedback than the students expected to have. The students also preferred unfocused feedback to focused feedback. The findings of the study have crucial implications on writing instruction. There is a need to design writing instructions which accommodate both teachers’ practices and students’ preferences for written feddback. Based on the profile of students’ preference and teachers’ practices, a model of feedback provision in teaching writing is proposed. This model is called preference-based feedback on writing instruction.
The implementation of conflict resolution phase III study showed that a win-win solution is beneficial to both sides of the conflict. The whole area is selected based on the amount of the most numerous mining and oil palm plantations which are plagued by the problem of external conflict, both with agencies and communities around the mines and plantations in East Kalimantan.The results of the implementation indicate that the conflict resolution is done through an integrated way with the principle of "win win". This has been proven through focus group forum that has agreed on a settlement process which is not detrimental to all parties though maximum expectations are not quite achievable. Several successfully resolved cases are disputed lands (mines and plantations) and the negative impact of the exploitation of the mine.In general, this is well received by all participants of the FGD, however, there are input / suggestions as follows: 1) the government must engage all elements and take responsibility for CSR programs that have been agreed, 2) agreed decision is not only tripartite coordination, but should include aspects of Coordination, Integration and Synchronization, 3) the Court should modify the rules based on Regional Acts, in which all decisions is not only relying on litigation, but also on the non-litigation, 4) It should incorporate aspects of mental development and HR potential of the local community through a variety of training (workshops) required by the surrounding community.Based on observations and FGD, it shows that this design can be done and turns out to be beneficial for all parties concerned, though there is an obstacle when claims for compensation are too high (replacement land with a maximum price) whereas the companies only want to replace with a low price supported by evidences are not owned by the local residents. However, the principle of "win-win solution" works well on solving the conflict that has been happening.
This study aims at collecting data on adults’ knowledge and behaviour on environmental degradation, government’s programs in resolving environmental degradation, and alternative solution to resolve the environmental degradation through holistic management design for adults.Qualitative research using interview guidelines as a reference for the interview was implemented in order to collect data on the adults’ knowledge; sample cases of environmental degradation completed with photos and interview guidelines were used to collect gather adults’ behaviour (response) toward environmental degradation; interview guidelines were used as a reference for FGD to collect data on government programs which were implemented to resolve environmental degradaion after coal mining The alternative solution to resolve environmental degradation was the outcome of research and development conducted by Hardoko et al. in 2016 in different districts; however, these disricts shared similar problem characteristics since they are located in the same province of East Kalimantan.The location of this research is Berau District, East Kalimantan Province. The research respondents were 10 adults who were above 40 years old and lived around the coal mining site. The respondents of government programs were 4 staff from Mining and Energy Agency and Environment Agency. It applied the descriptive analysis and categorisation in tables which was interpreted. The adults’ average knowledge on environmental degradation was in the category of good; while their behaviour on it was in the category of sufficient. The government programs which were implemented to resolve environmental degradation were in form of material assistance; however, there was not any non formal program to alter adults’ behaviour from destructive behaviour to protective behaviour.This study found that the government programs were not suitable to resolve the environmental degradation in which behaviour was the root cause for the problems.. Having found this, a solution was offered in form of the knowledge and behaviour management design based on holistic approach for adult learning program as an alternative solution for government in solving environment problems after coal mining activities. The design is holistic because it includes knowledge, attitude, and behaviour aspect with contextual environment media which is covered in three stages of learning activities.This research has never been conducted before; particularly on the topic of adults knowledge and behaviour after mining in Berau District, East Kalimantan Province. The three stages of learning in the holistic management design for adults in solving the environmental degradation were the outcomes of the developed research conducted by Hardoko et al. 2016.
The influence of Environmental, Social, and Governance (ESG) risks on bank stability has become a critical area of study in the banking sector. This study examines the influence of ESG risks on bank stability using unbalanced panel data from 134 commercial banks in Indonesia from 2003 to 2022. Employing a fixed effects model, the findings reveal a significant negative effect of ESG risks on bank stability, where higher ESG risks significantly reduce bank stability. Specifically, government-owned banks face a greater stability decline than private banks due to their often higher exposure to regulatory and reputational pressures. Smaller banks are more adversely affected than larger ones because they lack the resources and diversification to effectively mitigate ESG risks. Additionally, non-listed banks experience a larger decrease in stability than listed banks, as the latter tend to have stricter governance structures and more robust risk management practices. These findings underscore the need for tailored risk management strategies to address ESG risks, particularly for government-owned, smaller, and non-listed banks.
