Study Interest State Administrative Law, Implementation of Business Licensing for Laundry Services Activities in Barong Tongkok District, West Kutai Regency, under the guidance of Dr. Siti Kotijah S.H., M.H and Agustina Wati S.H., M.H. Business licensing is an important aspect in the implementation of business activities, including laundry service businesses that are increasingly growing in urban communities. Laundry businesses require official permits from the local government as a form of compliance with regulations governing economic activities and environmental protection. With licensing, the government can supervise business activities and ensure that business actors comply with operational standards, including in the management of domestic waste generated from the washing process. Laundry business licensing is also an instrument to ensure consumer safety and comfort. Business permits include technical and administrative requirements, such as location permits, environmental permits (UKL-UPL/SPPL), and operational permits from related agencies such as the Investment and One-Stop Integrated Services Agency (DPMPTSP). Without complete permits, business actors can be subject to administrative sanctions to criminal penalties, as regulated in various laws and regulations such as Law Number 32 of 2009 concerning Environmental Protection and Management. Research on laundry business permits is important to provide a comprehensive picture of the processes, obstacles, and legal and environmental implications that may arise if business actors do not comply with applicable licensing provisions. Social legal research, with field studies at the Investment and One-Stop Integrated Service Office of West Kutai Regency, Barong Tongkok District and Laundry businesses in Barong Tongkok, West Kutai. Laundry businesses that have permits are 7, while there are still many laundry businesses that do not have laundry business permits. Business actors do not have business permits, because the reason is that their business is small, and the permit process is very difficult, and business actors avoid paying local taxes.

The impacts of wastewater (liquid waste) include contamination and pollution of surface water and other water bodies utilized by humans, as well as disruption to aquatic life. Wastewater generated from plate washing processes in offset printing industries contains toxic substances that can harm the environment, such as ink pigments, additives, alcohol, and other hazardous chemicals. This study aims to reduce the environmental impact caused by plate washing wastewater. The method used in this research is the Jar Test, which is commonly applied to evaluate the effectiveness of coagulants in water and wastewater treatment. Based on the findings, this method successfully reduced the Total Dissolved Solids (TDS) level by 18%. These results indicate that the use of alum as a coagulant has a significant effect on altering the chemical composition of the plate washing wastewater, thereby contributing to pollution reduction

. PT. XY is a company engaged in the printing sector, especially in the security products sector, which is required to process its wastewater so that it can meet the required wastewater quality standards, especially in the processing of domestic waste originating from human waste and other consumption waste such as washing water, rinsing and so on. A Sewage Treatment Plant is a domestic liquid waste processing installation to process residual domestic liquid waste so that it becomes clear and is no longer harmful to the environment. The problem that arises is one of the measurement parameters in the wastewater quality standard, namely total coliform (coliform bacteria), which has not met the requirements for several months. This study aims to process domestic waste in the sewage treatment plant process with the six-sigma method to achieve results according to the requirements of the liquid waste quality standard. It is safe to be discharged into water bodies. The results of this study from 6 parameters 5 parameters meet the wastewater quality standards, namely: pH, Total Suspended Solids / TSS, Biochemical Oxygen Demand5 / BOD5, Chemical Oxygen Demand / COD, Oil and fat, while the average level of Total Coliform in a year is 6,448 MPN / 100 ml, not yet meeting the wastewater quality standards of 3,000 MPN / 100 ml. The results of the six-sigma calculation found a result of 1.5 Sigma (σ) where the process is in the non-competitive category

The presence of heavy metals in waste is one of the variables that can pollute and damage the environment. Lead is one of the chemical contents that can be found in hospital liquid waste. Hospital liquid waste comes from work unit processes throughout the hospital environment which contains dangerous chemicals so it needs to be processed before being discharged into the environment. Research has been carried out using the coagulation-flocculation method using sugar palm seeds as a biocoagulant. The aim of this research is to find out how the palm seed coagulant mass influences in reducing lead (Pb) levels. hospital wastewater with the addition of variations in coagulant mass, namely 0.3%, 0.4%, 0.5%, 0.6% and 0.7%. From the filtrate resulting from coagulation-flocculation which was then analyzed based on the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number P.68 of 2016 concerning Domestic Wastewater Quality Standards, from the results of this research it is known that sugar palm seeds as a biocoagulant are able to reduce the most optimal PB concentration when the coagulant concentration is added to 0.6%.

Car washes have become increasingly popular in some areas, but this growth has also had a negative impact on environmental quality, as untreated wash water is often discharged directly into car wash drainage systems without any prior treatment. This discharge of unfiltered wastewater can lead to high levels of COD (chemical oxygen demand) and surfactants in nearby water sources if carried out intensively. Much of the wastewater is often classified as waste. It is discharged by car wash operators into the drainage system and eventually into smaller waterways. In 2014, the Minister of the Environment highlighted the importance of managing cleaning waste due to its harmful effects on the environment and health. Based on the Pekanbaru Municipality's Regional Regulation No. 8 of 2003 on the payment of liquid waste treatment control permit, which stipulates that every industry must carry out waste treatment before discharging into the environment and each industry must also  pay a fee, this study will allow the design of absorption wells, which will be used to treat liquid waste from car washes, so that the wastewater absorbed into the ground is no longer a contaminated liquid waste. By treating the waste by the method of infiltration pits, it is hoped that the environment and the health of the residents around the laundry will be well preserved.
