Published: May 2023

Purpose- The purpose of this study is to find the location of errors in students' Arabic speaking skills and then overcome these errors with the error analysis method, and this research focuses more specifically on showing the analysis of verbal errors.
Design/Methodology/Approach- The method used in this research is descriptive qualitative, data obtained from interviews, observations, and documentation at the Pondok Pesantren Nurul Jadid Probolinggo. This study used a sample of 7th grade students with a total of 30 students.
Findings— During the process of learning Arabic, especially speaking Arabic skills, students are not able to distinguish and pronounce the sounds of Arabic letters properly and correctly. This causes phonemic errors that occur in the students of the Nurul Jadid Probolinggo Islamic Boarding School during the Arabic learning process. There are many phonetic errors that are often found in speaking Arabic, including errors in pronouncing the letters. Arabic has long vowels and consonants that other languages ​​like Indonesian don't have. There are even sounds that are close together and sounds that are firm are characteristics of Arabic which are often problematic in learning Arabic.
Research Limitation/Implications- Therefore the author divides from the mistakes made by the students to overcome them. This research could not be deeper because of the limited time given, even so this research got satisfactory results and it is hoped that it can help develop the maharah kalam learning process at the Nurul Jadid Islamic Boarding School Probolinggo.

Alih Kode dan Campur Kode Guru-Guru Bahasa Arab Pada Grup Whatsapp Majma’ Al-Lughah Al-‘Arabiyyah
Authors: Fauzan Ahyar , Nasrullah Ahmad , Hidayat Tatang
Published: May 2023

Objective: This study aims to mention examples of code switching or code mixing for Arabic teachers in the Majma' Al-Lughah Al-'Arabiyyah Whatsapp group, explain the meaning of code switching or code mixing used, and mention the factors that encourage the use of code switching and code mixing.
 Design/Methodology: This study uses a qualitative approach and a descriptive method. The researcher collected chat data from the Majma' Al-Lughah Al-Arabiyyah WhatsApp group related to code switching and code mixing, then performed data classification, analysis, and conclusion.
Findings: Researchers found 22 code mixing, and 6 code switching. While the factors that cause the use of code mixing and code switching are seven, namely: (1) Arabic speaking habits, (2) speakers do not master Indonesian, (3) limited meaning, (4) as a form of respect, (5) use of more popular terms, (6) enhance a sense of humor, and (7) speech situations. The most dominant factor is the speaker's habit of speaking Arabic and the speaker is not fluent in Indonesian, and the least dominant factor is the factor of increasing prestige.
Research Limitations/Implications: This research is limited to Arabic teachers at the Majma' Lughah Al-Arabiyyah institution, with a span of only two months. Even so, this research has been able to provide an overview of the use of code switching and code mixing in the Majma' Al-Lughah Al-Arabiyyah WhatsApp group as a whole.

Published: May 2023

Purpose- This study aims to analyze the errors in pronunciation of Arabic greetings (salam) to students of Madrasah Diniyyah Assalam Tegalombo Class VI and find out the implementation in Arabic learning.
Design/Methodology/Approach- This study used a descriptive qualitative method using a contrastive analysis approach. The validity of the data was tested by using triangulation technique. The data were obtained through field research.
Findings- Based on the results of the research on errors in pronunciation of Arabic greetings to Class VI students of Madrasah Diniyyah Al-Quran (MDA) Assalam Tegalombo consisting of 16 students, it was found 7 forms of pronunciation that were not in accordance with the original phonology of salam, example Assalamualaikum, Salamualaikum, Slamualaikum, Slamlékum, Saamlékum, Samlékum, and Smléikum. Of the 7 forms of pronunciation errors, there are 4 types of phonological errors, namely 1) Pronouncing "ع" to "أ" because the mother tongue does not have these consonants. 2) Pronouncing the wrong word structure because of al-akhtho 'al-syâi'ah. 3) The sound /ai/ becomes /é/ due to socio-cultural factors. 4) Do not extend consonant lam because the mother tongue does not have mad. The implementation is that in the future Arabic language teachers for foreign speakers can put more emphasis on the phonological aspect. Because in Arabic, different pronunciations and pronunciations will produce different meanings.
Research Limitation/Implications- The limitations of the problem in this study focused on the pronunciation of the greetings of students at Madrasah Diniyyah Al-Quran (MDA) Assalam Tegalombo class VI. However, this study has not examined further about the mispronunciation of the greeting answers.

Authors: Mubarok Husni
Published: May 2023

Purpose- Understanding the effects that homonyms and synonyms have on Fusyah Arabic word semantics. It is vital to understand the meaning of words and their use in Arabic through this study.
Design/Methodology/Qualitative- In this research, qualitative methods are used with library research, that is, finding all relevant information and reviewing it. By using inductive content analysis techniques, the data obtained were examined in depth and critically analyzed.
Findings- Synonyms and homonyms in Arabic have a semantic influence on sentences. Due to the way that homonyms words are arranged in Arabic texts and expressions, there is the possibility of misunderstanding the meaning of certain texts and expressions. Using synonyms incorrectly in Arabic can lead to errors in sentence composition, as synonyms convey the same meaning as other words, they are used interchangeably in a variety of contexts.
Researc Limitations/Implications- Due to time and reference constraints, this research did not cover specific scientific disciplines as far as Arabic texts relating to homonyms and synonyms are concerned. In general, the results of this study can be used as a basis for understanding homonyms and synonyms in Arabic

Published: May 2023

In the era of industry 4.0, it is so easy for students to take digital information instantly without any activity to ensure the validity of previous information. This study aims to analyze students' perceptions of digital literacy skills in fiqh learning at State Islamic University (UIN) Sunan Ampel Surabaya. This research is qualitative with phenomenological glasses. The informants in this study were 160 students. Brande filled out an online questionnaire through a google form containing statements related to the basic digital literacy skills that have been developed. Then we conducted a semi-structured interview on the informant's answer results directly. The results of the study revealed that students have a good perception of literacy skills. They are ready to use tools to search, dig, select and process information. However, students have not mastered the basic tools for learning fiqh, namely Arabic. Students experience problems when looking for fiqh information in Arabic. The recommendation in this study is that students will not be optimal in fiqh learning if they only have digital literacy skill but the fiqh learning base is not yet qualified. They need a fiqh website that is in Indonesian with credible and valid references.

Authors: Plugin A. N. , Trikoz L. V. , Gerasimenko O. S. , Podtelezhnikova I. V.
Published: May 2023

In the article the influence of the electro-surface potential value on change of the suspension viscosity values of pigments was investigated. It was done for pigments different in chemical nature – titanium oxide and ferric oxide. It was demonstrated that at equal dispersed phase concentrations the higher viscosity value was shown by systems with pigment TiO2 and the lower one – with Fe2O3. This fact correlates well with the absolute values of electrosurface potentials of the pigments studied. The active centers of the particles produce structuring effect on the dispersed medium molecules thus increasing the system viscosity.

Concentration of harmful substances reducing in surface layer of atmosphere at rheostat locomotive tests
Authors: E. A. Bondar
Published: May 2023

It is shown that at present an acceptable way of reducing the concentration of harmful substances in the surface layer of the atmosphere at rheostat tests of locomotives is their dispersion in a large volume of air. Channels, installed above an exhaust pipe of diesel locomotive with a break at the gas flow, work as ejectors. We have solved jointly the equation of aerodynamic characteristics of the ejector device and the equation of diffusion of gases; as a result the calculated dependence for determining the necessary height of ejector device has been obtained.
