Companies can help and improve communities in social, cultural, economic, and physical areas by carrying out corporate social responsibility. By doing so, they can make the community feel helped in improving their welfare If someone offers them help, they tend to see it positively because it is evidence of gratitude and empathy shown. The use of appropriate theories to study community empowerment and capacity building of the River School, including community empowerment through CSR programs, River Schools as a model of environmental education, the role of PLN CSR in environmental education at River Schools, early environmental awareness through CSR and River Schools, the impact of CSR programs on community empowerment and independence. This study uses a qualitative approach with a case study of community empowerment through PLN CSR to explore early environmental awareness The location of this research was carried out in Gunung Anyar Tambak Village Rt.01 Rw.01 Surabaya, which is an area used by Bank Sampah by PT. PLN (Persero). The PLN CSR program involving various parties in environmental education has a positive impact on shaping the mindset of the community who are more concerned about environmental sustainability. Awareness built early on, especially in children and adolescents, is expected to produce a generation that is more responsive to environmental issues. Counseling involving schools in this sub-district has proven effective in building a deeper understanding, which can then be passed on to their families. Therefore, it is important for PLN to continue to assist the community, provide adequate facilities and infrastructure, and provide incentives or awards for those who succeed in protecting the environment and managing resources wisely.

This research aims to determine the effectiveness of contextual learning approaches in subjects. Social Sciences (IPS) in Elementary Schools/Madrasah Ibtidaiyah based on literature review. The contextual learning approach is considered relevant because it allows students to connect lesson material with everyday life experiences, thereby improving students' understanding and critical thinking skills. The method used in this research is a literature study, where researchers collect and analyze various literature sources related to contextual learning and its application in social studies learning. These sources include books, scientific journals, and previous research that supports contextual learning theory and practice. The results of the literature review show that a contextual learning approach can increase student engagement, understanding of the material, as well as critical and analytical thinking skills. The contextual learning approach, based on evidence from the reviewed literature, is effective in improving learning outcomes and student involvement in social studies learning in SD/MI. Thus, this approach can be one of the recommended learning strategies to improve the quality of education in elementary schools.

<p>Sediment is material that is carried away and moves in the direction from flow of river water and settle downstream of a watershed. Changes in land use in the upstream watershed have the potential to increase sediment. Then, the increase in population will be proportional to the increasing need for land both for settlement and agriculture so that forest land will be looted and increase sedimentation. To overcome these problems, it is necessary to study the placement of sediment control buildings or check dams. Sedimentation is influenced by the amount of erosion. Erosion and sedimentation analysis were analyzed using Arc SWAT and from the results of the erosion analysis in the Tapin watershed, the average heavy class is less than 180 tons. Changes in sedimentation value from the dam plan to the present are 1.6 mm/yr until 1.8 mm/yr. Analysis used for selection of check dam locations is AHP (Analytical Hierarchy Process) Expert Choice. From the analysis of the selection of priority check dam locations Sub Watershed 1. The design flood discharge analysis for Q 50 years that uses ITB-2 method is 41.34 m³/second. The hydraulic aspect of the check dam in Sub watershed 1 is adjusted to the existing cross section of the river and prevous analysis, the results of analysis of sediment inflow are 6.592,05 m³/year and storage capacity is 49.132,00 m³, namely the building height is 3.75 meters.</p>
