Coal is the most important source of energy for electricity generation and serves as a basic fuel for industries such as steel and cement production as well as fuel for power generation. However, it is undeniable that the continuous use of coal also produces negative impacts from the mining process, namely acid mine drainage and coal processing in power plants, namely Fly Ash and Bottom Ash (FABA). Coal mining produces waste products in the form of acid mine drainage. FABA and Acid Mining Water (AAT) are two of the many negative effects of mining, so there is a need for awareness of the issues of damage that threaten the surrounding environment. FABA is solid waste produced from the coal combustion process for power generation. This study will discuss the use of FABA, alum and lime to neutralize acid mine drainage. Acid mine water obtained from PLTU X has a pH of 3.74. Neutralization of acid mine drainage is done by mixing AAT with FABA, AAT with alum and AAT with lime. Then proceed with mixing AAT with FABA and alum, mixing AAT with FABA and lime and mixing AAT with alum and lime. After that, mixing AAT with FABA, alum and lime. The results of this study provide variations in the composition of FABA, alum and lime which are good for neutralizing acid mine drainage Keywords: Neutraluzation, Acid Mine Water (AAT), FABA, Alum, Lime

The rapid growth occurring in the contemporary food and beverage industry during this era of globalization, driven by increasingly consumptive lifestyles, is the phenomenon examined in this study. One of the popular contemporary beverages today is Chatime. Chatime is widely known, especially among millennials such as college students. However, Chatime still receives negative responses from some of its customers. This may happen due to differences in individual preferences and varying customer expectations, meaning what is liked by most people does not always satisfy everyone, which is a problem addressed in this study. The factors suspected to influence customer satisfaction with Chatime are price, product quality, and service quality. The purpose of this study is to determine the impact of price, product quality, and service quality on Chatime customer satisfaction among Business Administration students at Politeknik Negeri Medan. This study uses quantitative methods, including validity tests, reliability tests, classical assumption tests, and hypothesis testing. The data analysis technique employed in this research is multiple linear regression analysis using SPSS version 26, with a sample of 94 respondents. Data collection techniques used in this study include questionnaires and literature studies. Based on the research results, price (X1), product quality (X2), and service quality (X3) simultaneously and partially have a positive and significant effect on customer satisfaction (Y). The results of the coefficient of determination (R2) test show that the variables of price, product quality, and service quality can explain 73.8% of the influence on customer satisfaction, while the remaining 26.2% is influenced by other variables not included in this study.

Currently, the problem of consumer behavior is the low level of consumer awareness of the needs of the goods they buy. Some consumers admit that the goods they buy are not what they really need, but they still make purchases. There are also those who reveal that they order goods on the marketplace just because they are visually tempted. This certainly contradicts the purchasing decision theory which explains that the higher the consumer's awareness of the need for the goods needed, the higher the purchasing decision will be, and vice versa. This research aims to analyze the influence of cultural factors, social factors and personal factors on purchasing decisions. The approach used in this research is a quantitative method. The sampling technique used simple random sampling with a total of 99 respondents, who were users of the Shopee application. Data was collected via an online questionnaire and processed using SPSS with multiple regression data analysis techniques. The results of this research show that simultaneously, cultural, social and personal variables have a significant and positive influence on purchasing decisions, as indicated by the significant value of the F test < sig value, namely <,0.001 < 0.05. And partially, social and personal variables have a significant and positive influence on purchasing decisions, which is aimed at the significance value of the t test for each variable < sig value, namely (0.005 and <0.001 < 0.5). Meanwhile, cultural factors are rejected which is aimed at the significance value of the t test variable > sig value, namely (0.132 > 0.05). They feel that although communities such as those for music lovers, gamers, or fashion can be a forum for sharing the same interests, not everyone feels the need or is interested in being active in the online environment in discussions or activities within it.
