Patient safety is a fundamental component of healthcare quality and a key indicator of hospital performance. Ensuring its implementation requires not only technical competence but also psychological and organizational support. This study aims to analyze the effect of motivation and coaching on the implementation of patient safety among nurses, with responsive culture as a mediating variable at Hospital X, Bekasi. A quantitative approach was employed using a cross-sectional design. Data were collected from 162 nurses in inpatient units using a structured questionnaire and analyzed with Structural Equation Modeling–Partial Least Squares (SEM-PLS) using SmartPLS software. The results showed that both motivation and coaching have significant direct effects on the implementation of patient safety. In addition, both variables significantly influence the development of responsive culture, which in turn also has a significant effect on patient safety. Responsive culture serves as a strong mediating factor, reinforcing the relationship between individual-level factors (motivation and coaching) and organizational safety outcomes. These findings indicate that motivated nurses who receive structured coaching within a responsive organizational environment are more likely to engage in safe practices. This study contributes to the growing evidence that human and cultural factors are critical in improving patient safety outcomes. It also provides practical recommendations for hospital leaders to focus on motivation strategies, coaching mechanisms, and cultural transformation to build safer healthcare systems. Future research is suggested to involve multiple institutions and integrate qualitative methods for deeper contextual understanding.

Background: The COVID-19 pandemic has significantly altered children's daily routines, particularly increasing screen time, decreasing physical activity, and changing sleep duration, which may impact their physical and mental health. It is important to know how changes in physical activity and screen time can affect children's sleep duration before, during and after the COVID-19 pandemic.
Methods: This study used a quantitative analytical observational cohort study method with 240 child samples aged 6–12 years in Semarang City. The sampling technique used simple random sampling. The research instrument used the SMALLQ® questionnaire. Data analysis techniques used normality tests, Spearman-Rank tests to determine correlations, and Kruskal-Wallis tests to compare data.
Results: The correlation between screen time and sleep duration was not statistically significant (p>0.05), while physical activity showed a significant positive correlation with sleep duration (r = 0.253 on weekdays, r = 0.21 weekly, p<0.05). Significant differences were found in screen time, physical activity, and sleep duration across the three periods (p<0.001), with increased screen time and decreased physical activity and sleep duration persisting post-pandemic. 
Conclusions: The pandemic led to lasting increases in screen time and decreases in physical activity and sleep duration among children. Promoting healthier routines is essential to mitigate these impacts in the new normal era.

Secondary metabolites are compounds produced by plants, microorganisms and animals through the process of biosynthesis or derivatives from primary metabolites. The maceration method is a simple way to separate bioactive compounds from plant material. Guava leaves contain secondary metabolite compounds which have medicinal effects such as antibacterial, antioxidant and anti-inflammatory. This simplicia leaf is soaked in 96% ethanol (using the maceration method) for 24 hours and concentrated using a rotary evaporator. Alkaloid, flavonoid and saponin tests show that guava leaves contain these three compounds. These compounds have potential for development in the pharmaceutical field.

Nipah Panjang Village in Kubu Raya Regency, Indonesia, has diverse mangrove forest vegetation. Meanwhile, the mangrove forest in Nipah Panjang Village has the potential threat of deforestation, so it is necessary to develop a management strategy. A mangrove management directive can be compiled with mangrove biophysical data and the social conditions of the surrounding community. Therefore, this study aims to examine the distribution of mangrove forest areas and their utilization by the community in Nipah Panjang Village. The method used in this study was GIS analysis to determine the distribution of mangrove forest areas. In this study, observations and interviews were carried out to determine the use of mangrove forests. The study results show that from 2013 through 2018, there was around 3.12 Ha of deforestation. Deforestation that occurred was much lower than the previous year. It was due to the implementation of a devolution policy that granted village forest permits in Nipah Panjang Village. Currently, the forms of utilization of mangrove forests in Nipah Panjang Village are the farming (apiculture)  of kelulut honey, forest honey farming, and crab farming with the concept of silvofishery and the development of ecotourism. This form of utilization needs to be maximized so that the community's welfare increases, ultimately maintaining the mangrove forest.

Indonesia, a leading palm oil producer, generates 1,250 tons of Oil Palm Empty Fruit Bunches (OPEFB) waste daily, typically disposed of through polluting combustion. This study explores repurposing OPEFB as a substrate for erythritol production, a popular sweetener with minimal impact on blood sugar. The research utilized Moniliella pollinis mutant SP5, a yeast capable of producing erythritol from various substrates. The process involved acid hydrolysis of OPEFB followed by fermentation. When fortified with 15% v/v molasses, OPEFB successfully served as an optimal carbon source for erythritol production, achieving a mass yield of 0.2878 g/g. Further improvement came through the use of ethyl methane sulfonate (EMS) mutagenesis, with the best mutant (mutant 7) reaching a yield mass of 0.3298 g/g and volumetric productivity of 0.0534 g/L/h. This research aims to advance Indonesia's self-sufficiency in erythritol production while providing a sustainable solution for OPEFB waste reduction, simultaneously addressing economic and environmental concerns.
