Abstract

This paper focuses on using self-compacting concrete (SCC) as a material in the repair technique given the advantages it presents in the fresh state, namely: stability, homogeneity, and deformability, because it perfectly matches the shapes of the surfaces to be repaired. The interest is mainly focused on the evaluation of bond strength at the interface: Repair/Substrate. The assessment is made via a repair applied to a half-cylinder of the ordinary concrete substrate (OC), by using as a repair material two classes of self-compacting concrete (SCC) of different strength (30 and 40 MPa), the interface bond strength obtained in this case is compared to that of a half-cylinder (BO) repaired with vibrated concrete (OVC) used as a reference control concrete. The rheological properties of the (SCC) used were determined with the aid of the Slump-flow, L-Box, V funnel, and stability under sieve tests. Mechanical properties include compressive strength, and tensile strength. The test to assess the interface bond strength of the specimens is based on a splitting tensile test (indirect tensile). Finally, to determine the type of failure produced after the test. The results obtained showed that self-compacting concrete appears to be a very promising material in the repair and rehabilitation of concrete structures. SCC offers good interfacial bonding and therefore gives satisfactory interface bond strengths.

Abstract

Lansia atau seseorang dengan usia di atas 60 tahun adalah kelompok rentan keluhan kesehatan dengan 40,7 persen dari populasinya mengalami masalah kesehatan. Tingkat kepatuhan minum obat lansia terhitung rendah menurut beberapa penelitian. Untuk memperbaiki kondisi ini, diperlukan sarana pendampingan untuk menjaga kepatuhan konsumsi obat pada lansia. Pemanfaatan teknologi dalam menyelesaikan masalah ini sangat mungkin, mengingat 46,7 persen lansia di Indonesia telah menggunakan telepon genggam. Penelitian ini bertujuan untuk merancang sebuah aplikasi bergerak yang dapat digunakan untuk menjaga konsistensi minum obat dan melakukan pencatatan minum obat pada lansia. Rancangan ini dibuat dengan menggunakan metode Double Diamond yang dikembangkan oleh Design Council pada 2005. Ada dua aturan utama yang harus dipenuhi dalam perancangan, yaitu simplify dan increase the size of interaction button. Rancangan ini dievaluasi menggunakan dua metode pengukuran usabilitas, yaitu Single Ease Question dan System Usability Scale dengan memberikan skenario penggunaan yang harus diselesaikan kepada calon pengguna.
