Abstract

Concrete is a combination of constituent materials which consists of hydraulic cement (portland cement), coarse aggregate, fine aggregate, water, and additives. Generally, the use of concrete starts from the bottom construction to the top construction. In use in under construction, concrete will be in a variety of environments, one of which is an aggressive environment such as brackish water. This study aims to determine the ratio of the compressive strength of concrete and the split tensile strength of concrete in a mixture of brackish water and the concrete's compressive strength at various slump values (25–50 mm), 75–100 mm), 150–175 mm), and (> 175 mm). This research method uses an experimental research method at the Civil Engineering Laboratory, Faculty of Engineering, Muhammadiyah Parepare, in June–August 2022. The research results obtained show that the brackish water mixture in concrete results in a 10% decrease in the material's compressive strength compared to normal concrete and split tensile strength. The compressive strength of brackish water-mixed concrete with slump variation (75–100) is an average of 2.67 MPa, which is 10.68% of the normal concrete compressive strength value of 25 MPa. The compressive strength of brackish water mixed concrete with slump variation (75–100) is the result of the highest concrete compressive strength compared to other slump variations, and the compressive strength of brackish water mixed concrete with slump variation (> 175) is the lowest in concrete compressive strength results compared to other slump variations.

Abstract

The purpose of this study is to find facts that are compatible with the implementation of the independent curriculum on learning interest and also the character of elementary school students who have carried out the learning process by implementing the independent curriculum itself, this research uses the survey method with data collection techniques using observation and also questionnaires while for The population of this study is 10 teachers and 22 grade IV students. The analysis includes validity and reliability tests, normality tests, linearity tests and hypothesis tests with the research results showing a significant influence between the implementation of the independent curriculum on students' interest in learning and character values ​​with a sig value of 0.000 where <0.05, this shows that the implementation The independent curriculum has brought many changes and influences on elementary school students, including the interests and character of students. Therefore, teachers need to use more learning processes with independent curriculum designs in each class and schools can prepare facilities and infrastructure so that they can produce optimal learning processes so that they get the expected results in accordance with the goals of the school itself and improve the quality of existing education in Indonesia.
AL-IDHAFAH, AL-NA’AT, AND AL-TAUKID: STRUCTURAL RELATIONS BETWEEN ELEMENTS IN ARABIC SYNTAX Sulfadli; Muslimin Resi; Hamzah

Abstract

This research aims to explain the structural relations between al-idhāfah, al-naʿt, and al-tawkīd in Arabic syntax and to delineate how their interaction influences meaning formation and functional distribution within the nominal phrase. This study is conducted because previous research has tended to discuss these three elements separately, resulting in a lack of an integrated analytical model that describes the hierarchical and semantic relationships between them. The study employs a qualitative-descriptive approach, analyzing data drawn from classical nahwu texts, modern Arabic corpora, and relevant contemporary research. Data were classified based on the patterns of element occurrence and analyzed through structural syntactic analysis methods to identify their functions, positions, and i‘rāb (inflectional) implications. The results indicate that idhāfah serves as a marker of possessive relations and semantic restriction, naʿt functions to provide descriptive modification that clarifies the referent, and tawkīd reinforces the reference both structurally and semantically. These three form dependency patterns that influence each other when present within a single phrasal construction. The novelty of this research lies in the formulation of an integrative relational model that combines syntactic functions, hierarchical structures, and semantic implications into a single operational analytical framework. This model provides a more comprehensive understanding compared to previous fragmentary studies. These findings have important implications for the teaching of nahwu, the analysis of modern Arabic discourse, and the development of computational linguistic applications that require more accurate mapping of nominal structures.
