Sanitation is part of environmental health science which includes the methods and efforts of individuals or communities to control and manage the external environment which is dangerous to health and which can threaten human survival. Meanwhile, basic sanitation is the minimum sanitation required to provide a healthy environment that meets health requirements which focuses on monitoring various environmental factors that influence human health. Basic sanitation efforts include providing clean water, disposal of human waste (latrines), waste management (trash cans) and waste water disposal channels (SPAL). Through a preliminary survey conducted at the Sahabat Yatim Dormitory Orphanage and from interviews conducted by the community service team, it was discovered that several children at the Sahabat Yatim Dormitory orphanage had a fairly high history of dengue fever sufferers and there were still many conditions in the orphanage that did not meet health requirements. Thus, there is still the possibility of problems related to environmental sanitation and eradicating mosquito nests (PSN) at the Pekanbaru Orphanage Friends Dormitory orphanage. The aim of this activity is to increase the knowledge of children in orphanages about environmental sanitation and eradicating mosquito nests.This community service was carried out at the Sahabat Yatim Dormitory Orphanage on June 29 2022. The method used was health education through group counseling. The result of this community service is to increase the knowledge of children in foster care about environmental sanitation and making compost.

Garbage is a problem that often occurs everywhere. One example is in Tanjungpinang City with various types of waste problems, one of which is plastic waste. For this reason, it needs to be handled seriously. One of the measures that has been carried out by the Tanjungpinang City government regarding the handling of plastic waste is to create a Tanjungpinang Mayor regulation policy no. 14 of 2022 concerning reducing the use of plastic bags. This regulatory policy was implemented on July 7 2022 and the policy of this regulation has been in place for approximately 2 years now. However, the results of implementing this policy regulation are still not as expected, with the data that has been presented in the background proving that every year there is an increase and plastic waste is in second place among the number of types of waste that exist. For this reason, this research aims to evaluate all forms of activities in implementing this policy using a descriptive qualitative approach according to the evaluation theory of Abdulkahar Badjuri & Teguh Yuwono (2002) which consists of 4 indicators, namely: suitability evaluation, effectiveness evaluation, efficiency evaluation and meta evaluation. Based on this theory, this research hopes that in the future this problem can be resolved and that regulatory policies run as expected so as to produce the desired results.

Based on data from the United States Department of Agriculture (USDA), global coffee production reached 170 million bags per 60 kg of coffee during the 2022/2023 period. Indonesia is noted as one of the largest coffee-producing countries in the world in 2023. The plastic packaging waste from coffee shops is increasing, posing a potential threat to environmental sustainability, such as soil and water pollution. According to Bizhare Contributor in 2023, the Food and Beverage industry in Indonesia has already reduced plastic waste, but there are still plastic packaging, particularly for coffee beans, that cannot be replaced with environmentally friendly materials. From this, the problem of this research is "How is plastic pouch waste sorted in coffee shops and how is it processed to become selling goods?". This research aims to determine the sorting of coffee pouch plastic waste in coffee shops and the processing process to make it into selling goods. The data collected through interviews shows that from the various coffee shops that have mushroomed in Jakarta, there are also coffee shops that care about the environment by sorting plastic waste. This coffee shop, namely Brookland Coffee, participates in donating coffee pouch waste to Demibumi, the process of making coffee pouches Environmentally friendly by Demibumi starts with collecting coffee pouch waste, cutting off the top, and sewing the outside with patchwork, then attaching it with adhesive so it can be folded. The conclusions obtained by DemiBumi prove that concrete action can be taken to overcome this problem. The main conclusion from this issue is that even though it is a big challenge, efforts to manage plastic waste can be successful and have a positive impact on the environment as long as it is carried out carefully by the community, such as through education, awareness campaigns, and the development of innovative solutions to reduce the use of single-use plastics can be steps. significant step.  

The purpose of this community service project is to train kindergarten teachers who belong to the Abimanyu and Banowati groups in waste sorting. The Community Based Participatory Research (CBPR) approach is used to carry out community service. Using this approach, kindergarten teachers and researchers work together to teach kids how to sort waste. Since waste sorting is a novel approach to waste management, it needs to be promoted and established in society, particularly among students. Most of the kindergarten teachers who took part in the program had never instructed their kids in waste sorting. Teachers of kindergarten received instruction on how to segregate waste in bins with red, yellow, and green lids. Kindergarten teachers can more easily teach sorting bins with colored lids to their kids. By imparting good values linked to teaching discipline, upholding cleanliness, and recognizing the health of their pupils, waste sorting training helps kindergarten teachers understand the significance of waste sorting.

Nephrons are the smallest functional units in the kidneys that are responsible for filtering blood, regulating fluid balance, and excreting waste through urine. When nephrons are damaged or diseased, kidney function can be significantly impaired. Nephron damage is usually caused by various factors, such as hypertension, diabetes, kidney infections, or certain drug toxicity. In the early stages, nephron damage can cause a decrease in glomerular filtration rate (GFR). As a result, metabolic waste products such as urea and creatinine accumulate in the blood, known as azotemia. Over time, progressive damage to the nephrons can trigger chronic kidney disease (CKD). In more severe cases, when most of the nephrons are no longer functioning, the kidneys lose their ability to maintain the body's homeostasis. This results in electrolyte imbalance, metabolic acidosis, and excess fluid buildup, known as end-stage renal disease (ESRD). At this stage, patients require renal replacement therapy such as dialysis or kidney transplantation to survive. Prevention of nephron damage is very important, including through the management of comorbidities such as diabetes and hypertension, adequate fluid intake, and avoiding exposure to toxic substances that damage the kidneys. Thus, the risk of kidney failure can be minimized.
