Abstract. Educational environment is needed in the education process, because the educational environment serves to support the process of teaching and learning, a comfortable environment and support for the implementation of an education is needed. The environment is distinguished into the biological environment, the non-living natural environment, the artificial environment and the social environment. Education is one of the first obligations for parents. In Islam, the person most responsible for the education of the child is the parent. The family is the "smallest people" who have leaders and members, has a division of work and work, and the rights and obligations of each member. The best exemplary education for children is if both parents are able to connect their child with the example of Rasûlullâh SAW, as uswah of all mankind. A positive school environment is a school environment that provides facilities and motivation for religious education. Keywords. Environment, Education   Abstrak. Lingkungan pendidikan sangat dibutuhkan dalam proses pendidikan, sebab lingkungan pendidikan berfungsi menunjang terjadinya proses belajar mengajar, lingkungan yang nyaman dan mendukung bagi terselenggaranya suatu pendidikan sangat dibutuhkan. Lingkungan dibedakan menjadi lingkungan alam hayati, lingkungan alam non-hayati, lingkungan buatan dan lingkungan sosial. Pendidikan merupakan salah satu kewajiban pertama bagi orang tua. Dalam Islam, orang yang paling bertanggung jawab dalam pendidikan anak adalah orang tua. Keluarga adalah “umat terkecil” yang memiliki pimpinan dan anggota, mempunyai pembagian tugas dan kerja, serta hak dan kewajiban bagi masing-masing anggotanya. Pendidikan keteladanan terbaik bagi anak, ialah jika kedua orang tua mampu menghubungkan anaknya dengan keteladanan Rasûlullâh SAW, sebagai uswah seluruh umat manusia. Lingkungan sekolah yang positif yaitu lingkungan sekolah yang memberikan fasilitas dan motivasi untuk berlangsungnya pendidikan agama. Kata Kunci.

<p>Avoiding faradaic side reactions during the operation of electrochemical devices is important to enhance the device stability, to achieve low power consumption, and to prevent the formation of reactive side‑products. This is particularly important for bioelectronic devices which are designed to operate in biological systems. While redox‑active materials based on conducting and semiconducting polymers represent an exciting class of materials for bioelectronic devices, they are susceptible to electrochemical side‑reactions with molecular oxygen during device operation. We show that this electrochemical side reaction yields hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>), a reactive side‑product, which may be harmful to the local biological environment and may also accelerate device degradation. We report a design strategy for the development of redox-active organic semiconductors based on donor-acceptor copolymers that prevent the formation of H<sub>2</sub>O<sub>2</sub> during device operation. This study elucidates the previously overlooked side-reactions between redox-active conjugated polymers and molecular oxygen in electrochemical devices for bioelectronics, which is critical for the operation of electrolyte‑gated devices in application-relevant environments.</p>

The Coastal Engineering Research Center at Fort Belvoir, Virginia, is responsible for research that supports the U.S. Army Corps of Engineers' Civil Works program. This research involves coastal navigation, channel design and maintenance, storm flooding, shore erosion control, and coastal ecology. The ecology research is focused on two major areas: (1) use of coastal vegetation for engineering purposes and (2) effects of coastal engineering activities on the biological environment. The objectives and accomplishments of the ecology research are discussed and specific examples of field guidance are presented.
