To compete with other stores, store owners need to design various strategies, one of which is understanding customer purchase patterns. This article examines the Squeezer algorithm and compares the performance of the Apriori and FP-Growth algorithms in forming customer purchase association patterns that can be used as a reference for store owners in planning sales strategies. The data mining process was carried out using Association Rules and Clustering methods. A total of 1256 sales transaction data samples were analyzed to understand the association patterns produced by each method. Based on the test results with a minimum support of 0.2 and a confidence of 0.6, the Apriori algorithm produced 194 association rules with a total rule strength of 1.16. Meanwhile, the FP-Growth algorithm produced 52 association rules with the same total rule strength of 1.16. The Clustering Method resulted in 7 clusters with a similarity value of 0.06322. After comparison, the FP-Growth algorithm proved to have better performance in generating association rules compared to the Apriori algorithm.

Grouping is a process or activity to develop a system that is more organized and easy to understand, making it easier to analyze, identify or manage data and can also be used to explore information so that it becomes new knowledge for anyone who wants to obtain it. and in this case the information we want to explore is about MSME data in Binjai City. Namely, it is difficult to know how to identify existing business development patterns, whether they are not yet developed, less developed, already developed, and very developed. Offline and online promotions have not been optimal in increasing the growth and change of a business from time to time. And most MSMEs still don't understand how to market their products and services effectively and efficiently. MSMEs are one of the most numerous community business groups in Binjai City. To obtain this information, one solution that can be implemented is by utilizing data mining using input data in the form of Binjai City MSME data. This data will be processed using the clustering method with the k-means algorithm using MSME business type variables, sales type variables and development pattern variables. .Based on the results of grouping Binjai City MSMEs using the K-Means Clustering Method from 20 grouped data, 3 clusters and 2 iterations were obtained where cluster 1 contained 4 data and was located in the MSME business type group, namely the businesses included in this cluster were businesses in the field of Fashion, for the sales type group, uses online and offline types, and for business development patterns, it has a development pattern that has developed. cluster 2 has 11 and is located in the MSME business type group, namely the businesses included in this cluster are businesses in the culinary sector, for the sales type group the offline type is used, and for the business development pattern it has a development pattern that has developed. and cluster 3 has 5 data and is located in the MSME business type group, namely the businesses included in this cluster are businesses in the culinary sector, for the sales type group it is using the offline type, and for the business development pattern it has a less developed development pattern. so it can be concluded that the pattern of business development of Binjai City MSMEs produces relevant data so as to produce designs that can be used for this research.

Coal mining activities often result in acid mine drainage (AMD), which can cause environmental pollution if not properly managed. This study aims to evaluate the potential use of fly ash from the Stream Power Plant (PLTU) Tenggarong to mitigate the impacts of AMD, specifically targeting iron (Fe), manganese (Mn), and pH parameters. Acid Mine drainage is formed when sulfide minerals oxidize, producing acidic compounds that can harm the environment. This research focuses on analyzing the ability of fly ash to adsorb iron and manganese from AMD solutions, as well its capability to increase solution pH. Based on the conducted research, the optimum pH value was achieved when using 10 grams and 15 grams of fly ash in the adsorption process. The optimum concentration of iron (Fe) was attained using 10 grams to 15 grams of fly ash, while for manganese (Mn), it was achieved with 20 grams to 25 grams of fly ash. The adsorption process using 25 grams of fly ash showed the highest efficiency in reducing iron (Fe) concentration by 93.78 % and manganese (Mn) concentration by 75.47 %.

The increasingly rapid development of the times has opened people's views to be more open to various kinds of world and national problems. Technology, which is one of the tools for thinking, has created innovative patterns of thinking in society that are mature in determining diverse perspectives and actions, as well as every outcome of views and attitudes that is permitted as long as it does not violate the rules and norms that have been regulated in state life. Customary forests are one of the categories of social forestry which are located in the living areas of local indigenous communities and can usually be found in inland areas. Customary forests are also regulated in Law Number 41 of 1999 concerning Forestry as stated in Article 1 number 6 "Customary forests are state forests that are within the territory of customary law communities." Conflicts between company interests and the rights of indigenous communities sometimes arise due to a lack of legal protection and unequal power, this is based on expansion which can be said to be irregular because quite a few mining companies expand mining areas outside the mine itself in order to exploit very natural resources. abundant in it.

Illegal mining in Indonesia isn't it things we just heard, In fact, illegal mining has become widespread in almost every region potentially rich in minerals. Illegal mining is the most common found is mining gold. Mining gold illegal or often in short for PETI (Unlicensed Gold Mining) is a mine amount pollution material the mine most tall. In Indonesia, gold mining without a permit is considered an unlawful activity, especially because miners do not have a mining business permit as a business entity. They do not pay taxes and royalties which are sources of state income from mining activities. Their activities also often cause social unrest and environmental damage. One that has gold mines is Jambi Province, precisely in the Merangin Regency area. Gold mines in this district are not only found on land but also in river basins (DAS). Merangin Police have carried out many prevention and law enforcement efforts to deal with mining activities without permits.

This study aims to evaluate the effectiveness of existing law enforcement related to environmental pollution in the Taluduyunu River. The method used in the study is normative and then analyzed in a descriptive qualitative. The results showed that the basis of law enforcement evaluation of the Taluduyunu River due to pollution of mining waste (Case Study Buntulia District, Pohuwato Regency). The results of this study revealed that law enforcement against river pollution due to mining waste is still not effective. Despite clear regulations regarding waste disposal, many mining companies have not fully complied with these regulations. Increased coordination between government agencies, the application of more stringent sanctions, as well as environmental awareness on the part of the industry are needed to thoroughly address this issue. To improve the effectiveness of law enforcement, there is a need for stricter policy reforms, increased capacity of law enforcement institutions, and closer collaboration between government, industry, and civil society in an effort to maintain environmental sustainability and public health affected by mining waste pollution.

Indonesia is one of the countries in Southeast Asia rich in nickel reserves, so this has become an attraction for foreign investors to compete to invest amid a drastic increase in market demand for lithium batteries for electric vehicles. Tesla, Inc. became one of the investors who showed interest in the potential for establishing a lithium-ion battery factory for electric vehicles. Indonesia is aware of Tesla's enthusiasm in trying to conduct intense negotiations and lobbying because these MNCs have several advantages in terms of advanced features and acceleration, as well as adhering to green principles. The author's aim in raising this issue is to reflect on Indonesia's long process of building government-to-business negotiations and lobbying with Tesla, where Indonesia sees this opportunity as a step to pursue national interests. The method used in this research is based on a literature study through secondary data collection. The findings from this research are that both Indonesia and Tesla use a rational approach and integrative strategy in negotiating investment cooperation. However, Indonesia's optimistic attitude is reflected in experiencing various challenges, including competition from competitors from other countries and unsustainable nickel mining problems.
