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.

Utilizing a mixed-methods approach, the study analyzes quantitative data from employee surveys and qualitative insights from interviews with public sector employees. The findings reveal a significant positive correlation between PSM and EP, indicating that employees who are motivated by a desire to serve the public tend to exhibit higher performance levels. Additionally, the research identifies key factors that enhance this relationship, including organizational support, leadership styles, and job design. The study highlights the importance of fostering a motivating work environment to improve employee performance in the public sector. Based on these findings, recommendations for future research and practical implications for public sector management are provided, emphasizing the need for targeted training programs and employee engagement strategies. This research contributes to the understanding of how intrinsic motivations can drive performance outcomes in public service settings.

This article examines various aspects related to khamar, including its linguistic meaning, definitions, impacts, and the Islamic legal perspective on it. In Arabic, khamar means something that conceals or covers, referring to intoxicating beverages that impair rational thinking. Scholars provide various definitions of khamar, encompassing intoxicants derived from fermented grapes and other substances. From an Islamic perspective, khamar is considered to have more harmful effects than benefits, affecting social, economic, and health aspects. Although the trade of khamar may provide worldly profits, it is deemed contrary to Islamic teachings due to its potential to promote immorality and corrupt morals. The impact of khamar consumption on minors is particularly damaging, affecting their physical and mental health as well as causing broader social repercussions. Islamic legal sanctions against the consumption of khamar emphasize strict prohibition to prevent its use, although specific worldly punishments are not elaborated upon. This study highlights that despite the financial advantages it might offer, the negative consequences of khamar far outweigh its benefits and should therefore be avoided for the well-being of society.
 
 

Waste management is a global issue and not a glamorous topic. On the global stage, climate and development discussions related to waste management have not yet become a top priority. Despite facing a global climate crisis, pollution, and biodiversity loss, the issue of waste management remains neglected, even at the household level. In Indonesia, the Integrated Waste Management Sites (TPST) are still predominantly managed through operational systems such as controlled landfills, open dumping, and sanitary landfills, which create mountains of toxic waste that pollute the air, contaminate water, harm public health, and accelerate environmental degradation. 54.43% of waste in Indonesia comes from households, with the total in 2024 reaching 19,502,650.23 tons, and 8,046,428.49 tons (41.26%) of household waste remains unmanageable. The impact of the COVID-19 pandemic has led to a decrease in household income, prompting community service activities aimed at solving two problems simultaneously: waste management and efforts to increase household income. As part of this initiative, the introduction of maggot farming technology (Hermetia illucens larvae) was implemented to improve household income. The community service was carried out at Posbindu Dahlia RW 001, Petukangan Selatan, as the area is a residential neighborhood with available vacant land not yet utilized by the operators of the Jakarta Outer Ring Road toll. This community service activity ran smoothly, achieving all its targets and bringing about changes in the knowledge and behavior of the participants, as well as enabling them to optimize small land areas for maggot cultivation, thereby increasing household income.

The problem of household waste management is one of the pressing environmental issues in various countries, including Indonesia. The high volume of waste that is not properly processed contributes to environmental pollution, such as soil, water, and air pollution. Tasik Rejo Village is one of the villages that focuses on waste management, this village has a BUMDes that is active in waste management but is only piled up at the TPS. Through Community Service activities, the service team carries out activities to change waste so that it can be utilized properly. The purpose of this service is to provide education and skills to Tasik Rejo village residents about the importance of maintaining environmental sustainability and a healthy lifestyle through waste processing, one of which is into fertilizer, so that waste can have value that can be utilized. This service method uses the ABCD method where the community plays an active role in every stage. Based on the results of the service, it can be said that the community is not fully aware of the importance of sorting waste, therefore further assistance is needed, but this service activity has a positive influence on changes in healthy living behavior in the community.

This research was conducted in order to participate in resolving the problems that occur in UMKM Processed Mina in the coastal areas of Central Java, especially the Sayung area. Many fish processing businesses in the area only pursue profits to help the household economy, considering that their business productivity has not developed/increased, which is likely due to a lack of attention to conscious efforts to carry out or comply with Occupational Health and Safety (K3), such as using personal protective equipment such as hand straps, boots, or in processing fish related to stoves, there are no manual extinguishers for home businesses. K3 attitudes and behaviors for those whose workers are mostly women, are not/may not yet aware of this. Efforts to foster K3 attitudes and behaviors are things that affect economic businesses, especially mina because productivity is increasing. The results of the study are expected to help the local village government to strive to improve their business.

One of the most profitable agricultural commodities is eggplant. Eggplants also need to be large enough to be eaten as vegetables or vegetables. Eggplant farmers in Indonesia often experience crop failure problems due to excessive use of chemical fertilizers, which make the soil acidic and harmful to the environment. Efforts to help the growth and development of eggplants by using compost. The focus of the research is to determine the effectiveness of various compost fertilizers on the growth and production of eggplant plants. It was carried out from July-September 2023 in Sidorejo Village, Langsa Lama District, Langsa City. In this study, a Non-Factorial Group Random Design (RAK) was used. The observed factor is various compost fertilizers, which consist of 11 composts with 1 variety of Mustang F1 eggplant which is repeated 3 times. The results showed that the treatment of various types of compost fertilizers had a real effect on the plant height parameters of 15 HST and stem diameter of 45 HST. However, it had an insignificant effect on the parameters of average fruit weight, fruit weight, number of fruit planted, average fruit size and production per hectare at harvest time. The benefits of this research are improving the quality of soil fertility, plants becoming fertile, and improving plant quality and productivity. The best result was obtained from K8 (gamal leaf compost), but it was as good as K7 (petai leaf compost). The application of compost fertilizer is effective for all parameters of eggplant plants, except for the treatment of K5 (bagasse compost) because the average value is below 100%, the most effective compost fertilizer is obtained in the treatment of K8 (gamal leaf compost), but it is as good as K4 (straw compost) and K7 (petai leaf compost). To cultivate eggplant plants, it is recommended to use gamal leaf compost, straw compost, petai leaf compost.
