Abstract

This study focuses on observing how much damage to concrete in the mixing and maintenance process using brackish water with variations in the type of cement brand and its effect on the compressive strength of concrete K-175 (Normal Concrete) with curing 28 days and knowing the relationship between the modulus of elasticity and strain on the compressive strength of concrete. The results showed that the highest compressive strength of concrete at the design age of 28 days was 253.790 Kg/cm² or 20,447 MPa using brackish water and a mixture of Gresik cement materials followed by Tiga Roda cement of 20.313 MPa, Conc cement of 19,506 MPa and Holcim cement of 17,236 MPa. So that the relationship between compressive strength and modulus of elasticity and strain due to cement variations shows a value of R = 0.9999 or reaches a value of 1 so that it has a very significant effect.

Abstract

In general, the water used for making concrete is water with a pH of 7, as well as the standard testing in the Lab, but in reality sometimes the work of making concrete in the field does not pay attention to the pH of the water used, such as the use of swamp water or well water made around the project site. The use of concrete structures that are in direct contact with sulfuric acid compounds will affect the quality of the compressive strength of concrete because sulfuric acid can corrode concrete. This study observes how much damage to the concrete if in the mixing and maintenance process using acid water with a pH level <7 and the effect on the compressive strength of concrete with curing duration of 3, 7, 14, and 28 days. The highest compressive strength of concrete at a design age of 28 days is 240,196 Kg/cm² or 19,237 MPa using acid water in a concrete mixture using Conch brand cement, followed by Gresik cement at 18,167 MPa, Tiga Roda cement at 16,837 MPa and Holcim cement at 16,837 MPa.

Abstract

The addition of other materials, especially natural fibers in normal concrete, certainly has its own way of analysis. The addition and in certain proportions may affect the behavior of the concrete structure as a whole. The effect of this change needs to be investigated to provide accurate information about the behavior and capacity of fibrous concrete, especially palm fiber. This study was to determine whether the addition of nipa fruit fibers increased the compressive strength of normal concrete mixtures, to determine the optimum level of addition of nipa fruit fibers that could affect the compressive strength of normal concrete. The compressive strength of concrete has increased with the addition of palm fiber as a substitute for some of the volume. The compressive strength of concrete with a variation of 0% is 19.640 MPa, a variation of 0.2% is 15,648 MPa, a variation of 0.4% is 11.875 MPa and a variation of 0.6% is 7.224 MPa. Partial replacement of nipah fruit fibers in the concrete mixture gave an increase in the compressive strength of concrete at 28 days with a variation of 0.2%. The design compressive strength fc' = 13.53 MPa while the resulting compressive strength is 15.648 MPa or an increase of 13.535%.

Abstract

Organisasi Pendidikan, Keilmuan, dan Kebudayaan Perserikatan Bangsa-Bangsa (United Nations Educational, Scientific and Cultural Organization/UNESCO) menunjukkan data persentase minat baca anak Indonesia berada di angka 0,01 persen. Angka itu berarti, dari 10.000 anak Indonesia, hanya satu anak yang senang membaca. Tentunya hal ini sangat memprihatinkan. Tidak hanya itu, disebutkan juga bahwa minat baca di Indonesia menempati urutan ke-63 dari 70 negara. Oleh karena itu, orangtua memiliki peran penting untuk menumbuhkan minat baca kepada anak, terutama anak yang masih berusia dini. Membaca sejak dini itu sangatlah  penting, orang tua sering menganggap bahwa masa kanak-kanak adalah masa bermain sehingga masa kecil mereka dihabiskan untuk bermain bersama teman sebaya.  Jika ada taman bacaan yang didirikan di lingkungan sekitar, hal itu bisa mengundang anak untuk datang dan membaca buku yang menarik sesuai dengan usia mereka. Orangtua bisa melakukan beberapa hal untuk menumbuhkan minat baca kepada anak, Salah satunya dengan membelikan buku yang menarik dan disukai anak. Sesuai minat anak-anak yang senang melihat gambar dan warna, Akan tetapi di era digital seperti sekarang ini, tidak semua sumber bacaan terutama buku dapat diakses dalam bentuk fisik, bisa juga diakses dan dibaca  dalam bentuk buku digital (ebook). Membuat dan mengembangkan sebuah Web yang mana Web tersebut berisi berberpa ebook (buku digital), dikarenakan tidak semua sumber bacaan terutama buku dapat diakses dalam bentuk fisik, Akan tetapi bisa juga diakses dan dibaca  dalam bentuk digital, Penelitian ini dilakukan dengan menggunakan metode penelitian kualitatif. penelitian yang digunakan untuk meneliti pada kondisi obyek yang alamiah, Sedangkan untuk teknik pengumpulan data menggunakan teknik  obeservasi, dokumentasi, dan wawancara mendalam. Dengan kehadiran buku digital telah mengubah kebiasaan membaca terutama dalam dunia pendidikan. Adanya buku digital tidak untuk menggantikan buku konvensional, ebook menjadi alternatif yang memudahkan seseorang untuk membaca buku.  Selain itu buku digital adalah media berbagi informasi yang mudah disebarluaskan. Sejauh ini buku digital merupakan pilihan alternatif sebagai sumber referensi, buku digital menyajikan informasi berupa teks, gambar, video, audio, maupun bentuk multimedia lain yang bisa dibuka melalui laptop, komputer, dan smartphone
