Abstract

One of the important skills for learning Arabic is the ability to write, or mahar al-kitabah. The purpose of this paper is to discuss the theories that support the scientific learning of Arabic writing skills. Methodologically, this paper is descriptive qualitative by investigating various relevant sources. The results of the study show that mastery of linguistic elements such as vocabulary, grammar, and writing rules is necessary to master writing skills. Students must also go through various steps, such as modeling, getting guidance, and independent writing, to achieve the learning objectives. By understanding this idea, it is hoped that the learning and teaching of maharah al-kitabah can be improved in educational institutions.

Abstract

This research aims to examine the use of the Muro'at al-Nazhir concept in the science of balaghah which is applied to Surah Ar-Rahman in the Al-Qur'an. Muro'at al-Nazhir is a rhetorical technique that emphasizes harmony in meaning, sound, structure, and even contrast of meaning in a text, thereby creating beauty and strengthening the message. Through a text analysis approach, this research identifies various forms of Muro'at al-Nazhir contained in Surah Ar-Rahman, including sound harmony through the repetition of the phrase "فَبِأَيِّ آلَاءِ رَبِّكُمَا تُكَذِّبَانِ" 31 times , harmony of meaning that describes the greatness of Allah and His blessings , harmony of structure through verses that have similar patterns, as well as harmony of opposing meanings that show the contrast between heaven and hell, as well as the creation of humans and jinn from different elements. The research results show that the use of Muro'at al-Nazhir in Surah Ar-Rahman not only adds to the beauty of the language, but also strengthens the spiritual meaning and messages of faith that are conveyed to humans and jinn. It is hoped that this study can deepen understanding of the art of balaghah in the Koran and inspire further study of rhetoric in this Islamic holy book.

Abstract

This study aims to analyze the perception of sounds in Arabic language learning at SMA Negeri 3 Medan. Sound perception refers to students' ability to recognize and produce sounds in Arabic, which often differ from sounds in the Indonesian language. This research identifies phonological difficulties experienced by students, the factors influencing their sound perception, and the teaching methods employed to address these challenges. The research methodology used is qualitative with a case study approach, involving observations, interviews, and phonology tests with 30 students and several Arabic teachers at SMA Negeri 3 Medan. The results show that students face major difficulties in distinguishing and producing certain sounds, such as the letters " ع " (ain) and " ق " (qaf), which do not exist in Indonesian. Psychological factors, such as lack of self-confidence, as well as teaching methods that lack structure in phonological instruction, exacerbate the difficulties students face. This study recommends giving more attention to phonological teaching, utilizing technology, and implementing blended learning methods to enhance students' sound perception in Arabic.

Abstract

Project construction is a type of activity where time, resources, and costs are controlled and discussed to achieve a goal in the form of buildings or infrastructure. The construction of infrastructure and project construction activities require about 70-75% of the national cement consumption. The use of cement in Indonesia will increase in line with the growth of the national economy and the development of infrastructure and property. To balance rapid growth, Kota Palangka Raya needs infrastructure development. The goal of this research is to understand the shape of the Causal Loop supply chain of cement in Kota Palangka Raya. In the research process, data analysis techniques using dynamic system methods with Vensim software are used.
