People are increasingly dependent on technology. On the other hand, companies’ large-scale investments to establish an ongoing loyalty with technology platforms and ecosystems show negative results. This is due to lower trust, concerns about risk, and increasing issues of privacy. Despite the continuous development of digital assistant applications to increase interactivity, however, there is no guarantee that the concept of interactivity is capable of gaining users’ trust and addressing their concerns. The purpose of the present study was to analyze the effects of controllability, synchronicity, bidirectionality on perceived performance and user satisfaction with digital assistant applications as moderated by perceived trust. Amos 22.0 was used to analyze a sample of 150 digital assistant users of brands Samsung Bixby, Google Assistant, Apple Siri, and other brands.Results show that bidirectionality is the most worrying feature in terms of perceived performance of digital assistants related to trust and privacy protection issues of personal data, whereas the other two features contribute to perceived performance and digital assistant users’ satisfaction. Perceived trust plays a role in moderating the relationship between controllability, synchronicity bi-directionality of perceived performance. Finally, perceived performance has an effect on digital assistant users’ satisfaction.

Older people risk poor nutritional status during natural disasters due to low intakes of energy, carbohydrates, protein, and fat. A food bar is a form of emergency food product that contains carbohydrate and protein, and is practical for disaster situations. The study aimed to investigate the effect of a broccoli-soybean-mangrove food bar on older people’s weight following natural disasters. A quasi-experimental pre-post intervention study was designed using 33 subjects at the treatment group of various nutritional status types of older people during two weeks with balanced nutrition education over two weeks. Bivariate analysis with a paired t-test used to test whether weight, macronutrient intakes, and balanced nutrition knowledge were significantly different before and after the study. The study showed broccoli-soybean-mangrove food bar consumption resulted in a significantly increased weight of 0.2 kg, energy (291.9 kcal), protein (6.1 g), carbohydrate (31.1 g), dan fat (15.6 g) intakes. Balanced nutrition education of older people could also substantially increase knowledge of older people regarding nutrition (11.8 points). The proportion of malnourished subjects who gained weight was more remarkable than normal subjects in the first and second weeks of the intervention. However, the proportion of normal nutritional status subjects having increased macronutrients intakes was higher than the malnourished subjects. These findings recommend broccoli-soybean-mangrove food bar consumption to significantly improve weight and macronutrients intakes in older people following a natural disaster. It is necessary to make the broccoli-soybean-mangrove food bar more available, accessible, and affordable to all people in emergencies, mainly for older people.

Indonesia is country with abundant high-risk areas for various disasters that can affect both the structural and non-structural safety of various vital establishments, particularly hospitals. This present study aims to examine the level of the hospital safety index in nine hospitals in four provinces based on the guidelines from the WHO/PAHO (World Health Organization/Pan American Health Organization). The Hospital Safety Index (HSI) guidelines consist of four parameters that include the types of hazards, structural safety, non-structural safety, disasters and emergency managements. This study was a cross-sectional study on data obtained through interviews, focus group discussions (FGDs), observations, and document reviews to assess the parameters of the HSI. Data were calculated for the HSI score, and descriptive statistics and multiple correspondence analysis (MCA) were carried out. The SPSS software version 25.0 was used for the statistical analysis. Results show that the overall safety index was 0.673 (Level A), meaning that it is likely the hospital will maintain functionality in emergencies and disasters. By province, the level A index was identified in DKI Jakarta (0.76), Yogyakarta (0.709), and West Java (0.673), showing that hospitals in these provinces will maintain functionality in emergency and disaster situations; however, in North Sumatera, the index was categorized in B category (0.507), demonstrating that the hospital’s ability to function during and after emergencies and disasters is potentially at risk. The multiple correspondence analysis shows that the hospitals in the provinces of Yogyakarta and West Java tend to achieve similar categories in almost all assessment modules; therefore, control measures of preparedness should be considered, such as improvements in equipment and facilities; hospital emergency and disaster response and recovery planning; communication and information management; training; and relevant stakeholders awareness.

The World Health Organization (WHO) defines the primary healthcare center (PHC) as a whole-of-society approach to health that aims at ensuring the highest possible level of health and well-being and their equitable distribution by focusing on people’s needs as early as possible along the continuum from health promotion and disease prevention to treatment, rehabilitation, and palliative care, and as close as feasibly possible to people’s everyday environment. PHCs are expected to remain operational when disasters occur. This study aimed to assess the PHC disaster preparedness level in Indonesia using The Hospital Safety Index (HSI) from WHO/PAHO. Eleven PHCs located in four provinces in Indonesia, i.e., Jakarta, Yogyakarta, North Sumatera, and West Java, were selected. Data were collected through interviews, focus-group discussions (FGDs), observations, and document reviews. The parameters assessed were all types of hazards, structural or construction safety, nonstructural safety, and functional attributes. The results show that the overall score of HSI for PHCs in Jakarta (0.674) and North Sumatera (0.752) fell into the “A” category, meaning that these PHCs would likely remain operational in the case of disasters. Meanwhile, the overall HSI scores for PHCs in West Java (0.601) and Yogyakarta (0.602) were between 0.36 and 0.65, or in “B” category, meaning that these PHCs would be able to recover during disasters but several services would be exposed to danger. The results suggested that there are several gaps that need urgent interventions to be applied for the structural safety of buildings, water supply systems, fuel storage, disaster committee organization, furniture and fittings, offices and storage equipment, as well as increasing the capacity of workers through a structured and systematic training framework for disaster readiness. The results from this study can be used for prioritizing budgets and resource allocation, cost planning, providing specific solutions for local and national government, and efforts to achieve disaster risk reduction.

The elderly population is of utmost importance amongst vulnerable populations during disasters because they experience reduced functional abilities, cognitive disturbance, dementia, weak physical conditions and various degenerative diseases. This study aimed to assess the effect of disaster preparedness training on knowledge regarding flood disaster preparedness and management in families with older people. This study was conducted using a quasi-experimental pre-post design with 30 participants in natural hazard preparedness training using purposive sampling. The results of this study showed a significant change in general knowledge on disaster and flood (12.9 and 20 points, respectively). Disaster preparedness practice was good, as reflected in actions performed before, during and after disaster. Before a flood occurs, families prepare a disaster preparedness bag for important documents as well as logistics (e.g. food) for emergencies and equipment for evacuation whilst also storing valuable goods in a safe place. During floods, families prioritise older people’s evacuation whilst seeking information about the flood through neighbours, walkie-talkies, handphones, television and radio as well as ensuring that the necessary logistics are taken care of. After the disaster, families clean their properties, provide clean water and toilet facilities for the family, check the health of family members that may be impacted by the flood and make sure that all electrical panels are safe. It is concluded that disaster training affects the knowledge of flood management in families with older people.

As there is a high number of urban communities and residential activities like electricity uses, transportation, food consumption, garbage production, and knowledge on climate change and carbon emissions, these affect the resulting carbon emissions in the city. However, the studies learn about the association between household and human activities, socio-demographic characteristic, carbon emissions and climate change knowledge on urban communities carbon emissions at Jakarta are still rare. This study aimed to assess whether daily human behavior, demographic variables, climate change knowledge, and carbon emissions knowledge affecting carbon emissions of urban communities. A cross-sectional study design was performed via a structured questionnaire survey and a jejakkarbonku application towards 200 respondents who were living in the two selected urban villages of Jakarta, Indonesia (Jatinegara and East Cengkareng). The results revealed that the mean urban communities’ carbon emissions in the region were 4.4 tonnes CO₂ eq/th. Electricity consumption in the kitchen and dining room produced the most carbon emissions (38.6%), and waste disposal activity produced the least (0.68%). Urban carbon emissions affected by employment status and income level, but not according to food consumption, garbage production, climate change and carbon emission knowledge. Climate change and carbon emissions knowledge influenced by marital and employment status. Although not significant, in theory, these two types of knowledge contribute indirectly to carbon emissions. Further research on the low carbon diet, intervention studies to increase deep awareness on the carbon emissions and climate change is needed to develop strategies reducing carbon emissions at urban communities.
