Abstract

The Segiri Sports Arena is an area that provides sports facilities for the people of Samarinda City and its surroundings. Various sports facilities are available, but as the city of Samarinda develops, the area has turned into a multifunctional area due to the activities carried out by the community. This transformation has caused the Segiri GOR area to look slum. In order to restore the main function and accommodate all these multifunctional activities with a better arrangement, as well as efforts to make a redesign that can become a landmark of the City of Samarinda, research is needed on the study of the redesign of the Segiri Samarinda GOR area with an approach to city landmarks. The parameters used are the landmarks and the characteristics of the sport building. This research would be useful for the government to improve and accommodate various functions of community needs for sports areas, and present new city landmarks for Samarinda City. This Samarinda City landmark brings elements of the distinctive character of the City of Samarinda in the form of the building.

Abstract

Beton merupakan salah satu bahan kontruksi struktur jalan, jembatan dan bangunan lainnya. Penelitian ini menggunakan tempurung kelapa dipecah secara manual sebagai pengganti agregat kasar batu pecah ½ . Pemilihan tempurung kelapa sebagai bahan campuran beton karena strukturnya yang keras, tahan air, tidak fleksibel dan tidak mudah dibentuk sehingga mampu mempertahankan kekuatannya sendiri. Kekuatan yang dimiliki tempurung kelapa diharapkan dapat mempertahankan atau bahkan meningkatkan nilai kuat tekan dan kuat tarik belah beton. Penelitian ini bertujuan untuk mengetahui pengaruh tempurung kelapa terhadap nilai kuat tekan dan kuat tarik belah dalam campuran beton normal. Dari hasil penelitian didapatkan bahwa penambahan tempurung kelapa sebesar 2,5% dapat meningkatkan nilai kuat tekan beton sebesar 7,7% dari beton normal. Sedangkan pada kuat tarik belah beton penambahan tempurung kelapa belum mempengaruhi kuat tarik hingga umur pengujian 28 hari, setelah umur beton 56 hari penambahan tempurung kelapa dengan kadar 2,5% dapat meningkatkan nilai kuat Tarik belah sebesar 0,08 MPa atau 1,7 % dari beton normal.Kata kunci : Tempurung Kelapa, Kuat Tekan Beton, Kuat Tarik Belah Beton.

Abstract

Pond ash concrete bond is expected to increase bond strength, because in previous studies pond ash concrete resulted in increased mechanical properties of concrete. Bond strength is the bonding mechanism between steel reinforcement and concrete in reinforced concrete construction as the main tool to transfer internal strength between reinforcement and concrete. In this study, a total of thirty-six cylinder concrete with a diameter of 15 cm and a height of 30 cm. Variations of the test parameters are three reinforcement diameters of 12 mm, 16 mm and 25 mm and two types of reinforcement namely plain reinforcement and deform reinforcement for normal concrete and pond ash concrete, using a 25 MPa normal concrete mix design and water cement ratio of 0.52. The results showed that the increase in bond strength on the plain reinforcement from 84.49 kg/cm2 to 91.33 kg/cm2 an increase of 8.09%, while for deform reinforcement there was in increase from 119.70 kg/cm2 in concrete normal to 131.32 kg/cm2 an increase of 9.71% in pond ash concrete. Split collapse occurs in deform reinforcement, whereas in plain reinforcement, slip collapse occurs.
