Along with human activities that continue to exist, it can be ascertained that the volume of waste will always increase along with the increasing consumerism of society every year. The impact is not only on the environment but also on human health. Therefore, a breakthrough in waste management is needed through the development of organic waste management in Kupang City into high economic value waste. The method used is a quantitative approach, namely to find out the stages of waste management in Kupang City and also the organic waste development model that needs to be done. Furthermore, a descriptive analysis was carried out on the opportunities for the use of organic waste in Kupang City, preceded by projecting the population of Kupang City. Afterwards, measurements of the composition and characteristics of household waste were carried out to determine the size of each component of the waste management system in Kupang City, which needed to be fixed from the source of waste. That was by sorting household organic and inorganic waste before being disposed of in a temporary dump according to the Government Regulation No. 81, year 2021, chapter 17, paragraph 1. However, the community does not comply with the existing regulations in reality. Therefore, it needs to be socialized to the waste-producing community. The stages of waste management in Kupang City are started by collecting waste from households, then the waste is transported using garbage carts or garbage motorcycles to temporary shelters at each point, and finally transported by garbage trucks to final disposal in Alak Village, Kupang City. The conversion of organic waste into high-value waste is accomplished by utilizing 67.5% of organic waste as biogas and compost.     

The state is an organization that has a purpose. The purpose of this study is to enforce the law regarding permits for waste water disposal in motor vehicle washing businesses and the sanctions imposed by the government on motorized vehicle washing businesses that do not have a waste water disposal permit. Normative juridical research, namely research originating from laws and regulations that present actual facts with the topic of study. Law enforcement of waste water disposal permits in motorized vehicle washing businesses through administrative instruments aims to prevent acts or omissions that violate the law or do not meet the requirements, stop or return to their original state (before the violation). So the focus of administrative sanctions is the actions of violators of the rules. In the Surabaya City Regional Regulation Number 12 of 2016 concerning Water Quality Management and Wastewater Control Article 34 explains the administrative sanctions referred to in the form of: written warning, Government coercion, Freezing of waste water disposal permits, Revocation of waste water disposal permits.

Waste is one of society's main problems in environmental management which until now does not have an appropriate handling solution. This is due to the community's habit of still implementing collection, transport and disposal in waste management, as well as the unavailability of suitable locations in each village that can be used as waste management sites. This waste problem is also experienced by residents of Sokawera Hamlet, Ciwuni Village, Kesugihan District. The waste produced by residents is usually collected and then burned. This waste management problem must be addressed immediately because it can affect the quality of life and the quality of the village environment. The effort taken is not to provide or create a waste disposal area, but rather to invite the public to start caring and being aware of the importance of managing waste wisely and correctly. This community empowerment activity is carried out by holding outreach and establishing a waste bank to change people's mindset about waste, mentoring, comparative studies, and establishing a Waste Bank to manage waste so that it can have economic value. With the formation of the Soka Resik waste bank, it is hoped that in the future it will become the spearhead in waste management.

Utilization of resources does not only focus on reforms but begins to enter into something that is even more unlimited, namely inspiration, ideas, talents or talents, and creativity. 3 main things form the basis of the creative economy, including creativity,  innovation,  and invention.  To support the creative economy  and the condition of the productive age population, the West Kotawaringin Regency government through the tourism office seeks to empower the community through a collaborative activity with one of the universities in Semarang, namely the Indonesian College of Tourism Economics (STIEPARI). The implementation  of activities ranging from identification, socialization to independent practice shows that there is an increase in awareness of the training participants to utilize local resources that can be processed into products even though they are made from waste which in this case is shells. This can be seen from the participants'  interest in applying the results of the counseling and training and continuing this activity to completion.

Chronic Kidney Diseases (CKD) is a disease condition where there is a decrease in kidney function, no longer able to carry out its function of filtering the blood, removing toxins and unable to remove waste products from the blood effectively, characterized by the presence of protein in the urine and a decrease in the glomerular filtration rate. Hemodialysis is a kidney replacement therapy method that is often used to manage CKD. The prevalence of CKD in Indonesia continues to increase every year with some patients undergoing hemodialysis. CKD patients undergoing HD are susceptible to anemia. Anemia in CKD patients can be caused by blood loss during dialysis procedures, and disturbances in iron metabolism. The aim of the study was to analyze changes in hemoglobin levels in CKD patients after undergoing hemodialysis. The research was carried out in a descriptive observational manner through an initial screening stage, an examination stage by measuring hemoglobin levels before and after the hemodialysis session and readings using a Mindray BC-5830. The examination results showed that the hemoglobin levels of CKD patients increased after undergoing HD. Hemoglobin levels in male CKD patients were higher than female patients both before and after undergoing HD. The conclusion of this study is that HD has an effect on increasing hemoglobin levels in CKD patients, both female and male patients.    

Snail Gong-gong (Strombus Turturella) is a typical food of the people of Riau Islands. The processed food produces the waste of a well-utilized shell. The main composition of the gong-gong slug is calcium carbonate (CaCO3). With the content of calcium, the waste shell of gong-gong can be used as raw material for the preparation of pharmaceutical preparations such as suction tablets. This study aims to obtain the formulation of a lozenges from the waste of gong-gong shell with good physical properties. A lozenges is made by a method of wet granulation in three formulas with variations in the concentrations of the case of the F1 gong-gong 15%, F2 30%, and F3 45%. The granules and tablets are evaluated. The results of the granule evaluation showed that the granule produced from the three formulas has fulfilled the requirements, the results of the tablet evaluation showed on organoleptic test, size uniformity, hardness, disintegration time of all three formulas have fulfilled good lozenges requirements. While the weight uniformity of F1 is not eligible, the friability test F1 and F2 are not eligible. The results of this study showed that the gong-gong snail shells can be formulated into a lozenges and have good physical properties.

Chronic renal failure is a progressive and continuous destruction of kidney structures. Chronic renal failure occurs in susceptible individuals, analgesic nephropathy, destruction of renal papillae associated with daily use of analgesic drugs for years. Whatever the cause, there is a progressive deterioration of kidney function which is characterized by a progressive decrease in the Glomelurus Filter Rate (GFR) (Corwin, 2009). Chronic kidney failure is a failure of kidney function to maintain metabolism and fluid and electrolyte balance due to progressive destruction of kidney structures with manifestations of accumulation of residual metabolites (uremic toxicants) in the blood (Muttaqin & Sari, 2011). as well as electrolytes and acid-base composition of body fluids, removing metabolic wastes that are no longer needed by the body, regulating blood pressure and hormonal function. Chronic Kidney Disease (CKD) is the final stage of chronic kidney failure where GFR <15 ml/min/1.73m2 so that the body fails to maintain metabolism and fluid and electrolyte balance, causing uremia, namely retention of urea and other nitrogenous wastes in the blood (Smeltzer et al. al, 2008; National Kidney Foundation in Kallenbach, et al, 2005). With the increasingly real decline in kidney function or worsening of symptoms of uremia, renal replacement therapy is required for survival, namely dialysis and organ transplantation. There are two methods of dialysis, one of which is Hemodialysis (Potter, 2005; Smelzer, 2008).     

The standard of living of the fishermen in Bandengan Village in general still lives below the poverty line. The condition of the houses which are semi-permanent as permanent residences even though the houses are close to each other accompanied by an environment that is still dirty and the unpleasant smell of fish waste whose drainage is not smooth adds to the poor environment. Healthy . Due to the slum and unhealthy environmental conditions, the fishermen of Bandengan Village are still able to survive in order to make a living even though they only fish to meet their daily needs.Regarding the position of deeper sea depths, generally fishermen have not been able to determine the exact position of fishing areas or have not mapped out exactly which areas have deeper depths and are thought to have lots of fish. From the data obtained, most of the overall fish catches have not increased. From the results of the analysis, this is because half of the fishing groups' fish catches have increased and half of the fishing groups' fish catches have experienced a decrease.Therefore, AMNI Maritime University has made the fishing community in Bandengan Kendal Village a Development Partner in order to improve the economy of the fishing community through optimizing fishing.

The main function of the kidneys under normal conditions is to regulate fluids and electrolytes and the acid-base composition of body fluids, remove metabolic wastes that are no longer needed by the body, regulate blood pressure and hormonal function. Chronic Kidney Disease (CKD) is the final stage of chronic kidney failure where GFR <15 ml/min/1.73m2 so that the body fails to maintain metabolism and fluid and electrolyte balance, causing uremia, namely retention of urea and other nitrogenous wastes in the blood (Smeltzer et al. al, 2008; National Kidney Foundation in Kallenbach, et al, 2005). With the increasingly real decline in kidney function or worsening of symptoms of uremia, renal replacement therapy is required for survival, namely dialysis and organ transplantation. There are two methods of dialysis, one of which is Hemodialysis (Potter, 2005; Smelzer, 2008). Cases of chronic kidney failure in the world have increased by more than 50%, in the United States which is a very developed country every year there are about 20 million adults suffering from chronic kidney failure and undergoing hemodialysis in more than 100,000 patients, while in Indonesia, according to the Indonesian Kidney Diatrans Foundation, YDGI), in 2007 there were about 100,000 chronic kidney failure patients but only a few patients were able to undergo hemodialysis. Kidney replacement therapy in Indonesia was started in 1972 in Jakarta (Dr. Cipto Mangunkusumo Hospital/FKUI), in Bandung in 1976 (Hasan Sadikin Hospital/FK UNPAD).

The purpose of this activity is to empower women by providing skills that can increase family income

Durian adalah tumbuhan tropis yang berasal dari wilayah Asia Tenggara, nama durian diambil dari ciri khas kulit buahnya yang keras dan berlekuk lekuk tajam menyerupai duri. Pohon durian merupakan pohon tahunan, yang berarti memiliki musim tertentu untuk berbuah. Pada musim raya durian pohon ini akan menghasilkan buah yang berlimpah, terutama sentra-sentra perkebunan di Indonesia. Pada 3 tahun terakhir tercatat rata-rata permintaan buah durian di Indonesia sebanyak 227,73 juta kg dan semakin meningkat pada tiap tahunnya. Pada umumnya masyarakat hanya memanfaatkan daging dan biji buahnya, dan membuang kulitnya begitu saja. Hal ini menyebabkan penumpukan limbah kulit durian. Dalam upaya mengoptimalkan pemanfaatan limbah kulit durian ini, perlu dibuat inovasi produk pangan berbasis kulit durian yang banyak diminati oleh berbagai kalangan. Kulit durian mengandung banyak lignin, selulosa, dan pati. Dengan adanya kandungan pati di dalam kulit buah durian, kulit buah ini dapat dijadikan tepung. Tepung inilah yang akan dijadikan bahan dasar dalam pengolahan pangan dan diharapkan dapat mendukung program diversifikasi pangan serta penurunan impor terigu. Salah satu inovasi olahan pangan kreatif dari buah durian ini, yaitu Makaroni Kulit Durian yang merupakan makanan ringan dengan berbagai rasa yang unik, membuat Makaroni Kulit Durian menjadi lebih populer dikalangan masyarakat sehingga dapat dijadikan alternatif buah tangan. Makaroni Kulit Durian juga memiliki masa simpan yang baik sehingga dapat meningkatkan nilai ekonomi dari kulit durian serta meminimalkan food waste.
