The rice straw waste is a byproduct of rice processing and is a plentiful natural resource in Indonesia. It has been utilized as a renewable energy source to decrease reliance on fossil fuels and tackle worldwide energy concerns. Rice straw waste contains various organic compounds, such as 36.6% cellulose, 25.3% hemicellulose, and 14.3% lignin. These compounds can be converted into various types of bioenergy, such as bioethanol, biogas, biomass, and bioelectricity through fermentation and pyrolysis processes. Rice straw waste has significant potential as a raw material in bioethanol production, biogas and bio-oil. rice straw waste also has the potential to produce bio-oil through the pyrolysis process. Tiny organisms, like bacteria and fungi, have a crucial part in the creation of bioethanol, biogas, and bio-oil. These microscopic organisms will be used in the process of fermentation, decomposition, or other biochemical reactions to convert rice straw waste into the desired renewable energy source. In the production of bioethanol, the use of enzymes such as amylase or cellulase may be required to break down the raw materials into simpler components that can be converted through the fermentation process into bioethanol. The process of producing biogas involves utilizing an anaerobic digester, which is a controlled environment devoid of oxygen. In this environment, microorganisms decompose the organic material found in rice straw waste and generate biogas. The methods used in the production of bioenergy (bioethanol, biogas and bio-oil) from straw waste may vary depending on the context and available technology.

The combustion of fossil fuels causes an increase in the release a group of gases found in the earth atmosphere that trap heat and contribute to the greenhouse effect, which in turn contributes to the occurrence of global warming. The advancement of sustainable energy sources plays an important role in human life due to renewable and environmentally friendly. This problem can be resolved by using alternative fuels as renewable sources of energy that are more environmentally friendly, such as bioethanol. Empty fruit bunches (EFB) constitute a portion of the solid waste that cause problems in storage, transportation, and processing costs. This is because EFB is waste in a solid that is produced from a processing facility where the fruits of the oil palm tree are processed to extract palm oil in large quantities. The process of producing bioethanol by utilizing coconut fruit bunches that are devoid of their contents as a raw material involves two essential stages: hydrolysis and drying. Hydrolysis with an acid catalyst results in a lower yield, but the catalyst itself is inexpensive. Conversely, when using enzyme catalysts, hydrolysis produces a greater quantity of reducing sugars. Enzyme catalysts can be employed in the simultaneous saccharification and fermentation (SSF) process using S. cerevisiae yeast, while chemical catalysts can be used in separate hydrolysis and fermentation (SHF) methods. The SSF method provides a comparatively elevated ethanol yield, demands less enzyme usage, has a shorter duration for ethanol production, and is environmentally friendlier when compared to the SHF procedure.

This study examines the work engagement of millennial employees at PT Jamkrindo in 2022. The work engagement level at PT Jamkrindo is reported to be high and has shown an improvement compared to the previous year. However, there are key areas that need to be the company's top priority, namely providing an adequate work environment and ensuring certainty in employee career development. Self-determination acts as a mediation factor, allowing the research to explore and understand the internal processes that occur in the minds and emotions of individuals. How individuals respond to and interpret the work environment and career development personally can explain why and how work engagement is formed, involving psychological factors such as individual goals, values, and self-perceptions. Based on the research findings, the work environment at PT Jamkrindo has a significant impact on the level of work engagement. Similarly, career development at PT Jamkrindo also significantly influences the level of work engagement. The work environment at PT Jamkrindo has a significant impact on the level of work engagement through self-determination as a mediating factor. However, career development at PT Jamkrindo does not have a significant impact on work engagement through self-determination. There is potential for further in-depth research, including a deeper understanding of specific factors in the work environment and career development programs that have the most significant impact on millennial employees.

Elections are a means to determine the fate of the nation for the next five years. For this reason, it is necessary to provide understanding through political education to the public, especially students who are classified as beginner voters with the aim of building student participation to participate in elections. As educators who have an important role in providing education in the field of politics to students, this research will analyze the role of political education in building student participation in elections. The aim of this research is to find out the role of political education in increasing student participation in the 2024 elections. The method used in this research is descriptive qualitative. The respondents or samples for this research were 120 FISIPOL UGN students. Based on the research results, it was concluded that students' understanding and knowledge of elections is still lacking due to the lack of political education provided. Student participation in taking part in the upcoming elections is in the good category, but still needs improvement because students' awareness of election participation is still limited to exercising their right to vote. Good education and students' low political attitudes will influence students' mindsets about things that can be followed in the implementation of elections.

Self-healing is healing that is called natural, because basically, humans are able to heal themselves in certain ways that are simple and comfortable.

Based on population projection data, it is estimated that in 2017 there will be 23.66 million elderly people in Indonesia (9.03%). The number of elderly people is predicted in 2020 (27.08 million), 2025 (33.69 million), 2030 (40.95 million) and 2035 (48.19 million) (Ministry of Health RI, 2017). The prevalence of dementia (per 1000 people) in Indonesia in 2005 was 191.4 incidents, in 2020 it is estimated to be 314.1 incidents, and will increase in 2050 to around 932 incidents. The data obtained in the work area of the Telaga District Public Health Center were 134 elderly , of which 38 had dementia. From the results of interviews obtained from health workers at the puskesmas and families, they said that often the elderly forgot many activities such as bathing, taking medicine and others, so the family had to remind them to take a bath, take medicine and so on . Further interviews conducted by researchers on the elderly, some said that they rarely consume vitamins, especially vitamin D, are lazy to exercise, do light activities or sunbathe every morning which can increase the risk of developing dementia.

According to WHO (2019), in the Southeast Asia region the elderly population is 8% or around 142 million people. In 2050 it is estimated that the elderly population will increase 3 times from 2013. In 2000 the number of elderly is around 5,300,000 (7.4%) of the total population, while in 2010 the number of elderly is 24,000,000 (9.77%) of the total elderly reached 28,800,000 (11.34%) of the total population. Data from the Central Bureau of Statistics shows that the elderly population in Indonesia in 2007 increased to 18.7 million people, then in 2010 it increased to 23.9 million people (9.77%). In 2020 it is predicted that the number of elderly people will reach 28.8 million (11.34%). Based on data from the Republic of Indonesia Ministry of Health (2019), Indonesia is entering a period of aging population, where there is an increase in life expectancy followed by an increase in the number of elderly people. Indonesia has experienced an increase in the number of elderly people from 18 million people (7.56%) in 2010, to 25.9 million people (9.7%) in 2019, and is expected to continue to increase in 2035 to 48.2 million people (15.77%) .

 
 
Abstract . A hospital is an institution or health service organization with broad and comprehensive functions, dense in expertise and capital intensive. Hospitals carry out broad functions so they must have resources, both capital and experienced and professional humans. Nursing service is part of the health service system in hospitals which has the function of maintaining the quality of service, which is often used as a barometer by the community, in assessing the quality of hospitals, thus demanding the professionalism of nurses in their work as shown by the results of the performance of nurses, both implementing and nursing nurses. management in providing nursing care to clients. Maximum implementation of nurse work in quality health services occurs when the nursing care implementation system supports professional nursing practice according to standards (RI Law No. 38, 2014). Motivation is the factors that exist within a person that moves and directs his behavior or encouragement that causes him to do something or do something to satisfy individual needs to achieve certain goals (Rini, 2015).

Trauma requires immediate and appropriate treatment. Because if the handling is not right or wrong it will result in further complications, such as infection, damage to nerves and blood vessels so that it can result in further soft tissue damage. Knowledge is the result of knowing and this has happened after a person runs his senses on a certain object. This sensory process occurs based on the five senses of every human being, namely the sense of sight, hearing, smell, taste and touch ( Notoadmodjo , 2014).
