One of the negative impacts of the mining process is acid mine drainage which is formed from the oxidation of minerals containing iron sulfur, such as pyrite (FeS2) and pyrothite (FeS) by oxidizers such as water and oxygen. To handle or control acid mine drainage, one way is to use activated carbon or often referred to as activated charcoal, which is a type of carbon that has a very large surface area. Charcoal is a porous solid that contains 85% to 95% carbon, produced from materials containing carbon by heating at high temperatures without oxygen (pyrolysis). Activated carbon made from palm shells is an adsorbent that can be used to treat coal mine acid water, so that the water meets standards for flowing into the environment. This study used concentration variants of 4 grams, 6 grams, 8 grams and contact times of 30 minutes, 60 minutes and 150 minutes. The results of this study show that the concentration of palm oil shell activated carbon adsorbent influences the reduction of iron (Fe) and manganese (Mn) metal levels as well as the pH conditions in acid mine drainage water. The higher the concentration and the longer the contact time, the more heavy metals are adsorbed, the contact time is the highest. The optimal concentration in this study was 150 minutes and the optimal concentration was 8 grams with physical activation.

Inquiry learning strategy is an educational approach that places students at the center of the learning process by encouraging them to actively seek, discover, and conclude knowledge through questioning, observing, and critically analyzing. In this strategy, students are not passive recipients of information from the teacher but are directly involved in learning activities that demand critical and analytical thinking skills. Through inquiry learning, students develop critical thinking abilities by engaging in stages such as problem formulation, hypothesis development, data collection, and drawing conclusions based on observations and analysis. This approach has been proven effective in enhancing students’ critical thinking skills as it promotes active and independent participation in learning, while also boosting motivation and self-confidence. The teacher acts as a facilitator who guides and motivates students to sharpen their critical thinking skills in solving problems systematically and logically. Thus, inquiry learning strategy not only enriches students’ understanding of the subject matter but also equips them with essential thinking skills to face future life and learning challenges.

This article discusses the implementation of negotiation strategies and lobbying techniques as participatory communication approaches in the context of community service in Parigi Village, Cikande Sub-district, Serang City. Through intensive community organizing, this activity aims to strengthen the capacity of residents in facing the challenges of cross-interest communication and collaboration, especially in terms of policy advocacy and local resource management. The service subjects consisted of local community groups who had been less involved in the decision-making process at the village level. The service process is carried out through several stages, starting from joint problem mapping, training in negotiation and lobbying techniques, to the preparation of collaborative action plans that involve active participation of residents. The findings from this activity show that interest-based negotiation and ethical lobbying can strengthen the community's bargaining position towards external actors such as the government and local stakeholders. The dynamics of the activity also resulted in initial social changes, such as the formation of an internal advocacy group, increased participation in public forums, and the emergence of collective awareness of the importance of strategic communication.

General Elections (Pemilu) are one of the important moments in democratic life in Indonesia. Indonesian elections are a true expression of democracy and a means for the people to declare their sovereignty over the state and government.

Settlement is a basic human need that is closely related to the feasibility of life and well-being. The purpose of this study is to gain a better understanding of settlement patterns that occur in rural and urban areas, and to investigate the factors that influence these patterns. This study collects, analyzes, and synthesizes related literature. The results show that settlement patterns in urban areas are denser and develop vertically, while settlement patterns in rural areas tend to be spread out and horizontal. Various factors, such as natural conditions (such as climate, topography, water and land availability), socio-economic factors (such as employment, education, and income), and government policies and local cultural developments, influence these differences. These results emphasize that understanding settlement patterns as a whole is essential to building areas that are equitable, sustainable, and responsive to community needs.
