Mine acid water is acidic water and contains iron and sulfate, which is formed under natural conditions when geological strata containing pyrites are exposed to an oxidizing atmosphere or environment. One of the impacts of the mineralization zone where there is a mining process is the potential for the formation of acid mine drainage, especially in the Cibaliung gold mineralization area and its surroundings, Pandeglang Regency, Banten Province. Acid-forming sulfide minerals include pyrite (FeS2), headquarters (FeS2), picoliters (FexSx), calcocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), galena (PbS) ) and sphalerite (ZnS). Of all these minerals, pyrite is the most dominant sulfide in acid formation. Alkaline mine water (alkaline mine drainage) is mine water that has an acidity level (pH) of 6 or more, containing alkalinity but still containing dissolved metals that can produce acids. The quality of mine water, acid or alkali, depends on the presence or absence of acid mineral content (sulfides) and alkaline materials in the geological strata. Acid water formation tends to be more intensive in mining areas. This can be prevented by avoiding exposure to sulfide-containing materials in the free air. Acid-forming sulfide minerals include pyrite (FeS2), headquarters (FeS2), picoliters (FexSx), calcocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), galena (PbS) ) and sphalerite (ZnS). Of all these minerals, pyrite is the most dominant sulfide in acid formation. Formation of potential acidic water also occurs in tailings which are residues/processing residues containing sulfide minerals. The formation of acid mine drainage does not always develop in every sulfide-ore mining. In certain types of ore deposits, there are neutralizing agents which prevent the formation of acid mine drainage.

Indonesia, Indonesia is a nation of law that uses a rule of law country (rechtstaat) concept. The concept of rule of law Indonesia set forth in its Constitution, the 1945 Constitution, Article 1 paragraph (3). There is an important element of democracy stated on the Constitution, namely the protection of human rights, that every citizen has the right to enjoy it. One of the rights protected in the Constitution is right to access a good and healthy living environment. For this, the environment needs to be preserved and function through administrative law enforcement. The study uses normative juridical approach with descriptive-analytics, which describes the norms and associated with theories, and opinions of legal experts. The development of a democratic nations of law can be seen from the aspect of law enforcement in particular with environmental administration. In Indonesia, it can be reviewed through the theory of organic states and the theory of pluralist states. Based on the theory of an organic state and looking at the aspects of environmental administration law enforcement in Indonesia, the state has regulated the enforcement of environmental administrative sanctions whereby the state can regulate every activity and/or business in the environmental issues. Therefore, the pluralist state theory recognized a variety of diverse interests in society that the state has accommodated all citizens rights to a good and healthy environment through pro-environment government policies

Independence is a crucial asset that children must develop from an early age to face the challenges of the digital era, yet studies that specifically evaluate the success of the 9 Pilar Karakter program of the Indonesian Heritage Foundation (IHF) in fostering independence among young children remain limited. This study aimed to examine the implementation and effectiveness of the 9 Pilar Karakter program in shaping independence in early childhood at BA Islamiyah Pesen, Kanor Subdistrict, Bojonegoro. A qualitative case study approach was employed with 14 children in Group A as the research subjects. Data were collected through observation, interviews, and documentation, and were analyzed using the interactive Miles and Huberman model, which includes data reduction, data display, and conclusion drawing. The findings show that implementation of the program through three main activities—knowing feeling, tell a story, and acting feeling—contributes to transforming children into more independent and self-confident individuals in their daily activities and learning context. These results affirm that the 9 Pilar Karakter program plays a strategic role in strengthening independence and socio-emotional character in early childhood. The implications of this study highlight the importance of optimizing the implementation of the 9 Pilar Karakter program as a foundation for children to navigate learning processes at subsequent educational levels as well as in everyday life.
