Abstract

ABSTRACT This study aims to determine the steps for the formation of religious character in children by Islamic Religious Education teachers at Tarbiyatul Falah Junior High School Ciampea Bogor. This type of research is qualitative descriptive. The subjects in this study were teachers of Islamic Religious Education at Tarbiyatul Falah Middle School, Ciampea Bogor, while the informants in this study were two class VIII students, one teacher at Tarbiyatul Falah Middle School Ciampea Bogor and the principal, Tarbiyatul Falah Junior High School Ciampea Bogor. . The results of the study concluded that: the pattern of religious character formation by Islamic religious education teachers in Tarbiyatul Falah Junior High School students in Ciampea Bogor was quite good because in the Tarbiyatul Falah Junior High School Ciampea Bogor environment, they were very accustomed to discipline, the pattern formed by Islamic Religious Education teachers. The discipline of worship can be applied in direct education for example through teaching and learning activities, example, motivation and supervision in performing worship, through the habituation of dhuha prayers in congregation and midday prayers in congregation and also indirect education by providing discipline to students so that students do not do bad things. in the environment. Keywords: Pattern of students' character formation

Abstract

Self compacting concrete (SCC) memiliki beberapa keuntungan dibandingkan dengan beton konvensional karena mengalir dan menyebar dengan berat sendiri dan mampu melewati celah-celah tulangan tanpa bantuan vibrator sehingga menghemat tenaga kerja. Abu batu merupakan hasil dari proses penghancuran bongkahan batu menggunakan alat pemecah batu (stone cuser). Tujuan penelitian ini untuk mengurangi sebagian semen dengan penggunaan abu batu yang divariasikan setiap variasinya. Penggunaan superplasticizer berpengaruh terhadap flowability dan workability. Pengujian beton segar dilakukan dengan 3 metode yaitu Slump Flow, V-Funnel, dan L-Shape Box. Pembuatan benda uji menggunakan silinderberukuran 100 mm x 200 mm dengan umur beton 28 hari. Hasil penelitian menunjukkan beton segar memenuhi karakteristik beton SCC dengan variasi SCCN, SCC 5%, SCC 10%, dan SCC 15% AB. Pada penelitian ini pemakaian abu batu tertinggi sebagai substitusi sebagian semen pada variasi 5% abu batu menghasilkan kuat tekan 25,72 MPa. Sedangkan pemakaian abu batu 10% mengalami kuat tekan yang menurun sebesar 21,15 MPa. Sehingga penurunan kuat tekan dapat diketahui berdasarkan rasio penurunan berturut-turut semua variasi terhadap beton SCC 5% yaitu sebesar 17,797%, 34,756%, dan 42,075%. Sedangkan pada beton SCCN nilai kuat tekan mengalami peningkatan terhadap beton SCC 5% sebesar 2,564%. Dapat disimpulkan bahwa semakin tinggi persentase abu batu pada penelitian ini dapat menurunkan kuat tekan beton yang diperoleh meliputipengujian Slump Flow, V-Funnel, dan L-Shape Box.
