Abstract

The rise of books and theories of human development written by psychology experts from both western and Islamic scientists has encouraged writers to contribute to writing theories of religious development experienced by a person when they reach puberty. We still encounter children in society who have reached puberty but are not yet fully aware of their obligations in practicing religious law. This prompted the author to conduct an analysis regarding religious obligations in the puberty phase. An overview of this religious development as explained in the Al-Qur'an and Al-Hadith, with reference to the Book of Tuhfatu al-Maudud fi Ahkami al-Maulud chapter ahkamuhu 'inda Bulughihi al-'Asyirotu by Ibnu Qoyyim Al-Jauziyah. This research aims to analyze the phases of puberty based on the Al-Qur'an and Hadith which are then completed and clarified by a literature review referring to the book by the 7th century AH scholar, Ibnu Qoyyim Al-Jauziyah, and equipped with several references from books and journals relevant to the title. This research uses library research with the object of research being the Book of Tuhfatu al-Maudud fi Ahkami al-Maulud chapter ahkamuhu 'inda Bulughihi al-'Asyirotu by Ibnu Qoyyim Al-Jauziyah. The results obtained from this research are a written work that can be used as a guide for the general public in guiding the awareness of practicing their religion in children of puberty, which includes the initial steps in introducing religious cognition and daily worship practices until the end of their lives.

Abstract

Land subsidence in the areas of Pademangan, Ancol, Penjaringan, Cengkareng, Tanjung Priok, Cilincing, and Pulogadung is still ongoing. The land subsidence is influenced by the condition of the groundwater table and the effect of consolidation. The purpose of this research is to know the result of soil subsidence/ consolidation using conventional calculation methods and geodetic GPS observations on R.E. Martadinata Street on Bore Hole 3 with Point BM.CP.1 and Bore Hole 6 with Point BM.DKI.11 and to find out the results of the comparison of subsidence/ consolidation analysis methods between conventional calculations and geodetic GPS observations. The amount of soil subsidence/ consolidation with conventional calculation methods at Bore Hole 3 with Point BM CP.1 obtained 8.5 cm with a period of 2.3 years and at Bore Hole 6 with Point BM DKI.11 obtained 5.6 cm with a period of 0.4 years. The amount of soil subsidence/ consolidation with GPS Geodetic observations BM CP.1 point was obtained at 16.8 cm with a period of 3 years and at the DKI.11 BM Point obtained 17.5 cm with a period of 3 years. The results of soil subsidence/consolidation calculations using conventional calculation methods and GPS Geodetic observations there was a difference or deviation in Bore Hole 3 with Point BM CP.1 obtained 8.3 cm with a period of 0.68 years and in Bore Hole 6 with Point BM DKI.11 obtained 11.9 cm with a period of 2.64 years.

Abstract

Educational philosophy is an integral part of the principal or foundation that aims to promote education quality. Islamic education is the focus for most Muslims, so it is necessary to develop the values or philosophical principles of Islamic education itself. This study aims to determine the philosophy of Islamic education and the basic foundations of Islamic educational institutions. The research method uses qualitative with a literature study approach, emphasizing secondary sources obtained from books, journals and official reports. The study results explain that education requires a strong foundation or foundation for the majority of Muslims through Islamic educational institutions. It needs to be thoughtfully developed based on Islamic religious knowledge from the Al-Qur'an and hadith; then, Islamic scientific progress will progress. Building a philosophical orientation of Islamic education must pay attention to the concept of the growth of knowledge strongly driven by the Al-Qur'an and hadith as inspiration in achieving competitive Islamic educational institutions. Efforts to instil educational philosophy in Islamic educational institutions are required to guide and investigate knowledge from its source sincerely. The framework in Islamic educational institutions must contain the principles of ontology, epistemology, and axiology. The research implies civilization's progress in achieving Islamic education with an inseparable educational philosophy value. Keywords: Educational Philosophy, Basic Foundation, Islamic Educational

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui bagaimana kualitas audit dipengaruhi oleh profesionalisme, etika, dan fee audit. Partisipan dalam penelitian ini adalah auditor yang bekerja di Kantor Akuntan Publik (KAP) yang berbasis di Surabaya. Purposive sampling digunakan untuk melakukan pengambilan sampel, dan 50 responden merupakan keseluruhan sampel. Uji asumsi klasik, seperti multikolinearitas, heteroskedastisitas, dan uji normalitas, dilakukan sebelum analisis data. Uji statistik deskriptif, uji validitas, dan uji reliabilitas juga dilakukan. Regresi linier berganda juga digunakan dalam penelitian ini. Sementara itu, uji simultan (uji F), uji koefisien determinasi (R2), dan uji parsial (uji t) adalah jenis pengujian hipotesis yang digunakan. Hasil pengujian hipotesis penelitian ini menunjukkan bahwa, berbeda dengan fee audit yang tidak memiliki dampak yang nyata terhadap kualitas audit, etika dan profesionalisme memiliki dampak yang besar. Penyebaran kuesioner di wilayah Surabaya merupakan salah satu kelemahan penelitian ini.

Abstract

Mathematics education in Indonesia faces significant challenges, as reflected in the low performance of students in various international assessments. Traditional teaching methods, which are less interactive, are considered one of the key factors contributing to students' low problem-solving abilities in mathematics. This meta-analysis aims to evaluate the impact of Polya's heuristic model on students' mathematical learning outcomes and determine the extent to which this strategy can enhance students' learning abilities compared to conventional teaching methods. The study employs a meta-analytic approach, integrating data from 15 primary studies conducted between 2014 and 2023, and uses statistical analysis to calculate the average effect size of the implementation of Polya's heuristic model in mathematics education. The findings reveal a significant improvement in students' mathematical learning outcomes using Polya's heuristic model, with an average effect size of 1.13, categorized as "very high." The study suggests that the application of Polya's heuristic model is significantly more effective in enhancing students' mathematical learning outcomes than conventional teaching methods. The practical implication is that educators and policymakers in Indonesia could consider adopting this strategy in curricula and teacher training programs to improve the quality of mathematics education.
