Abstract

This paper examines the correlation between compressive strength, porosity, and ultrasonic wave propagation in mortar. The research was conducted at the Yogyakarta State University Building Materials Laboratory. The study used an experimental method, mortar was made with variations in the ratio of cement and fine aggregate 1:3, 1:4, 1:5, 1:6, and 1:7 with a phase of 0.48. The manufacture of test objects in the form of a cube measuring 5x5x5 cm refers to SNI 03-6825-2002. Tests were carried out at the age of 3, 7, 14, 21, and 28 days with three samples per test age. The data was processed by quantitative descriptive method to determine the relationship between the variables, especially the relationship between wave propagation speed and compressive strength, as well as its relationship with the porosity value. The results of compressive strength and wave propagation speed are directly proportional to the age of the test. With the results of the compressive strength at 1:3, 1:4, 1:5, 1:6, and 1:7 variants, respectively 31.12 MPa, 19.83 MPa, 12.25 MPa, 5.38 MPa, and 3.89 MPa and wave propagation speed of 3827.67 m/s, 3641.7 m/s, 3561.3 m/s, 2019,0 m/s, and 1691.0 m/s. Then the porosity values are 11.12%, 12.88%, 16.36%, 17.60%, and 22.06%. The compressive strength has a correlation that is directly proportional to the logarithmic speed of wave propagation, the higher the value of the compressive strength, the higher the UPV value, and inversely proportional to the porosity value as well as the speed of the wave propagation which is inversely proportional to the porosity value. The higher the porosity value, the lower the compressive strength value and the UPV value.

Abstract

Pasar modal syariah di Indonesia menjanjikan potensi besar dalam mendukung pertumbuhan ekonomi yang inklusif dan berkelanjutan Penelitian ini menyelidiki evolusi pasar modal syariah dan pengaruhnya terhadap perekonomian Indonesia. Dengan menganalisis variabel yang mempengaruhi pasar modal syariah serta kontribusinya terhadap pertumbuhan ekonomi, penelitian ini bertujuan untuk memberikan pemahaman tentang peran pasar modal syariah dalam mendorong pertumbuhan ekonomi yang berkelanjutan. Penelitian ini menggunakan ulasan literatur sistematis (SLR), yang memberikan gambaran mendalam tentang tingkat pengetahuan saat ini tentang topik ini. Hasil penelitian menunjukkan bahwa pasar modal syariah telah berkembang pesat, tetapi potensinya masih belum dieksplorasi sepenuhnya. Pendanaan untuk sektor-sektor produktif, inklusi finansial, dan investasi berkelanjutan adalah beberapa cara pasar modal syariah membantu pertumbuhan ekonomi Indonesia. Perkembangan pasar modal syariah juga dipengaruhi oleh regulasi pemerintah, pendidikan masyarakat, dan kerja sama antarlembaga. Pasar modal syariah dapat memaksimalkan potensinya dengan meningkatkan literasi keuangan, menyederhanakan regulasi, dan memperkuat infrastrukturnya. Dengan demikian, pasar modal syariah memiliki kapasitas yang lebih besar untuk memajukan pertumbuhan ekonomi yang inklusif dan berkelanjutan di Indonesia. Kata Kunci : Pasar Modal Syariah, Kontribusi, Faktor-Faktor Pertumbuhan.
