Abstract

Beton adalah campuran yang terdiri dari bahan material berupa agregat halus, agregat kasar, semen, air, serta bahan lain sebagai tambahan dengan dosis tertentu. Bahan tambah yang digunakan yaitu berupa silica fume dengan dosis 0-10% dari berat semen. Dan penelitian ini bertujuan untuk pengurangan penggunaan semen serta mengetahui kuat tekan yang dihasilkan penggunaan silica fume 5% dan 15% pada umur beton 7 hari dan 28 hari dengan masing-masing 3 benda uji silinder. Metodelogi yang digunakan dalam penelitian ini metode eksperimen. Bahan-bahan yang digunakan dalam membuat campuran terdiri semen tipe 1 OPC (Ordinary Portland Cemen). Agregat halus yang digunakan berupa pasir cimalaka. Agregat kasar yang digunkan berupa split 1-2 (70%) dan 2-3 (30%) ex Tomo. Bahan tambah mineral additive silica fume. Bahan yang digunakan sudah diuji sebelum dipakai. Dan dalam membuat mix design atau perhitungan komposisi campuran beton menggunakan metode DOE (Development of the Environment), dan dosis penambahan silica fume 5% dan 15%. Dari hasil pengujian kuat tekan silica fume powder powder 5% umur 7 hari diperoleh sebesar 23.46 MPa (78.21%) dan untuk silica fume powder 15% diperoleh sebesar 20.0 MPa (66.67%), dan silica fume powder 5% pada umur 28 hari diperoleh sebesar 32.12 MPa (107.05%) dan untuk silica fume powder 15% diperoleh sebesar 35.96 MPa (119.87%). Kesimpulan pada umur 7 hari kuat tekan dengan kandungan silica fume powder 5% lebih besar daripada 15% dan umur 28 hari kuat tekan silica fume powder 15% lebih besar daripada 5%. Ini menunjukan silica fume powder memiliki sifat mereduksi panas semen dan meningkatkan kuat tekan pada umur beton tua. Serta dapat mengurangi penggunaan semen sebesar 5%-15%.

Abstract

The research dealt with the texts of the reading subject in the Arabic language book for the third intermediate grade and its related rules. This is based on the observation of the researcher who discovered a lack of consistency between the sentence structures included in the reading subject and the structures studied in the grammar subject. The research aimed to identify the suitability of those texts contained in the reading subject and the rules accompanying them, and to come up with structural proposals in order to modify the researched book. The research followed the descriptive approach, using observation as well as qualitative analysis methods in processing the research data. The research reached two results, the first of which is that the reading material in the Arabic language textbook for the third intermediate grade in 2020 AD is not grammatically appropriate. Some of the texts included in the reading subject did not cover the most important topics explained in the grammar subject. The second is that the writing of educational books and the preparation of their materials must be based on psychological, cultural, educational and linguistic foundations, consistent with their cognitive, skill and emotional objectives, achieving the principles of harmony, progression and balance, and taking into account the desires of the learners and the individual differences between them

Abstract

Al-insyâ’ al-thalabiy is one of the rhetorical methods, and it is one of the chapters of the science of meanings. One of the methods of that section is the matter. The book Al-Hosn Al-Mukhtar from Sahih Al-Adhkaar includes this method, with different meanings according to the context of the hadith and the context. It is difficult to comprehend those intended meanings due to the inability of learners to understand them, especially in the science of rhetoric. This research aims to know the hadiths that include the style of the command and its meanings in the book Al-Hosn Al-Mukhtar from Sahih Al-Adhkar. And this research followed the descriptive analytical approach. The results of this research are developing the linguistic exercises learned from the imperative style in the book Al-Hisn Al-Mukhtar from Sahih Al-Azkar using the inductive method, which consists of observing examples of the style, then deducing the general rules for each style with the exercises

Abstract

This research discusses the concepts of population and sampling in quantitative research, as well as the selection of participants/key informants in qualitative research. The aim of this study is to provide a clear understanding of these concepts and how they are applied in different research methods. The method used in this research is a literature review, analyzing relevant and reliable sources. The results show that in quantitative research, the population refers to the entire group being studied, while sampling is the technique used to select a representative sample from the population. In contrast, qualitative research emphasizes the selection of participants/key informants who are considered to have in-depth and relevant information related to the research topic. Further discussion reveals the importance of selecting the right sample or informant to ensure the validity and relevance of the data obtained. In conclusion, sampling in quantitative research should follow strict procedures to ensure the results are generalizable, while selecting informants in qualitative research prioritizes the depth and quality of the information gathered.
