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.

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).
