Abstract

Saat ini pembangunan RSUD Kota Probolinggo terdapat issue terkait akses masuk ke rumah sakit. Pada kondisi eksisting terdapat jembatan yang menghubungkan Jalan Prof. Hamka dengan rumah sakit yang memiliki perbedaan elevasi cukup besar. Hal ini mengakibatkan kendaraan yang akan keluar-masuk dari rumah sakit mengalami kesulitan untuk melewati jembatan tersebut. Berdasarkan hal tersebut maka Pemerintah Kota Probolinggo melalui Dinas Pekerjaan Umum, Penataan Ruang, Perumahan dan Kawasan Permukiman Pemerintah Kota Probolinggo melakukan kerja sama pengabdian kepada masyarakat dengan DKPU ITS untuk membuat kajian detail desain peninggian jalan pada Jl. Prof. Hamka, agar mempunyai beda elevasi yang tidak besar dengan jembatan jalan akses menuju RSUD Kota Probolinggo. Desain jalan ini dilakukan dengan menggunakan data topografi area sekitar jalan, data tanah, data hujan dan data lalu lintas serta diskusi dengan pihak BBPJN VIII Wilayah Jawa Timur dan Bali. Hasil dari desain peninggian jalan didapatkan tebal perkerasan kaku adalah 55 cm dengan perkuatan geotekstil dan dinding penahan tanah, dimensi saluran tepi dengan menggunakan U-ditch 50x50x120 cm dan box culvert 80x100x120, pemasangan rambu, marka dan penerangan jalan umum. Hasil dari studi tersebut digunakan untuk membantu operasional RSUD Kota Probolinggo terkait perbaikan akses masuk rumah sakit dari jalan nasional.

Abstract

Mangunsari Village is one of the goat farming centers in Gunungpati District, Semarang. They raise goats from generation to generation and based on experience, so care patterns are often not uniform from one to another. In addition to feed, animal hygiene and health are very important to implement in enforcing biosecurity in the pen and its surrounding environment. The goal of this activity is to improve goat health and the safety of the pen environment through biosecurity. The community service is divided into two: providing materials and training followed by practice. Twenty participants, members of the Mekar Sari 2 livestock farmer group, were accompanied by a team of nine lecturers, technicians, and students. The activity began with filling out a questionnaire, theory, and ended with practice. Data obtained showed that 53.8% were aged > 50 years and 23.1% were < 40 years. In addition, 84.6% of participants had been members of the livestock farmer group for a long time (≥ 10 years). There was a 0.2% increase in knowledge regarding infectious diseases, a 2% increase in leaf and grass feed, a 61.6% increase in forage that must be wilted, and a 7.7% increase in pen cleanliness. Participants also understood that forage is best not provided wet (40.5%). The results concluded that this activity improved knowledge about biosecurity components and the participants' skills in physical examination of goats and pen cleanliness.

Abstract

This study examines the messages of hope expressed by Syrian child victims of war in the music video Daqat al-Qalb (Heartbeat) composed by Zade Dirani in collaboration with UNICEF. Using a descriptive qualitative method, the research applies Ferdinand de Saussure’s semiotic framework to analyze how linguistic and visual signs interact to construct meaning. The analysis focuses on two primary components: (1) signifiers in the Arabic lyrics that articulate pain, fear, emotional struggle, and aspirations for change, and (2) visual symbols such as rubble, white flowers, collective movement, and bright colors that reinforce the thematic representation of hope. The data were obtained through close reading and repeated observation of the video, with additional secondary sources providing contextual support on the Syrian conflict and semiotic theory. The findings reveal five dominant categories of hope represented in the video: the hope to escape suffering and destruction; the desire to eliminate fear; the yearning to be heard and acknowledged by the world; the aspiration to gain strength and rise together; and the vision of rebuilding a brighter, more vibrant life. These categories demonstrate that the children are not merely depicted as passive victims but as active agents articulating their trauma, resilience, and collective dreams. The study contributes to visual-verbal semiotic research by showing how audiovisual media can effectively convey humanitarian messages and represent lived experiences of children in conflict zones. Despite the limitation of using non-official Arabic lyric sources, the findings highlight the power of symbolic interaction in shaping emotional and humanitarian meanings within music videos.

Abstract

The aim of this research is to analyze the phenomenon of code-switching and mixing in daily conversations in Arabic-Indonesian between students in the religious program at Darussalam Institute, Ciamis, West Java. This research employed a qualitative descriptive field method. The data consists of students' utterances in daily conversations and the results of interviews. Data were collected through observation and interviews. The research findings showed that there are multiple forms of linguistic switching, both external and internal, which occur through transitions between sentences or phrases depending on the context of communication. Additionally, code mixing was also found in the form of inserting Arabic words, phrases, or terms into sentences in Indonesian, enriching communication and reflecting the comfort and flexibility of the students' language. Factors influencing the occurrence of code-switching and mixing include the characteristics of the speaker, proficiency in Arabic and Indonesian, effective communication needs, formal and informal situations, as well as the presence of the other party and third parties in the interaction. The transition from formal to informal situations also enhances the use of these two phenomena to make communication smoother and easier to understand. These results emphasize that code-switching and mixing are not merely linguistic phenomena but also reflect the social and cultural dynamics in the school environment.

Abstract

Wadjda is a Saudi Arabian film directed by Haifaa al-Mansour and is the first film to be selected as the official representative of the Kingdom of Saudi Arabia at an international film festival. The dialogues in this film contain numerous instances of linguistic politeness principles. Therefore, this study aims to identify utterances that employ politeness principles and to describe the forms of those utterances. This research employs a qualitative descriptive method, with the film Wadjda as the data source. The data consist of utterances produced by the main and supporting characters that contain politeness principles. Data were collected using an observation technique, while data analysis was conducted through orthographic transcription followed by data classification based on Leech’s (1983) theory of politeness. This study applies Leech’s (1983) politeness principle, which comprises six maxims: the tact maxim, generosity maxim, modesty maxim, approbation maxim, agreement maxim, and sympathy maxim. The results reveal 13 utterances that employ politeness principles, consisting of three utterances of the tact maxim, three of the generosity maxims, three of the modesty maxims, three of the approbation maxims, one of the agreement maxims, and one of the sympathy maxims. Based on these findings, the most dominant politeness principles are the tact maxim, generosity maxim, modesty maxim, and approbation maxim. The findings of this study are consistent with the research conducted by Setiyono et al. (2021), which states that main and supporting characters tend to adhere to the tact maxim, generosity maxim, and modesty maxim.
Dinamika Habitus dan Modal dalam Hara: Analisis Struktur Sosial Pierre Bourdieu terhadap Tiga Cerpen Najib Mahfuz: The Dynamics of Habitus and Capital in Hara: Pierre Bourdieu's Social Structure Analysis of Three Short Stories by Najib Mahfuz Zaid, Muhammad; Buana, Cahya; Mawardi , Mawardi; Daulay, Heeral Manna; Faiz, Mohammad

Abstract

This study aims to analyze the dynamics of complex social structures in Najib Mahfuz's literary works through the lens of Pierre Bourdieu's sociological approach to literature. The background of this study is based on Hara's central position in Mahfuz's narrative, which serves as a microcosm of Egyptian society, marked by value conflicts and power struggles. Using a qualitative descriptive method with a textual approach, this study dissects three selected short stories: "Zakirat al-Jiran" (Memories of Neighbors), "Al-Hutaf" (The Call), and "Sada al-Nisyan" (Echoes of Forgetfulness). The analysis specifically applies Bourdieu's triadic concept of Habitus, Capital (economic and Symbolic), and Field, or Arena, to uncover the hidden mechanisms of domination. The study's results reveal diverse manifestations of social structures. "Zakirat al-Jiran" depicts the phenomenon of hysteresis of habitus, where conflicts continue to be reproduced blindly despite the loss of their historical roots, indicating the stagnation of tradition. "Al-Hutaf" highlights the violent clash between Economic Capital and Symbolic Capital, where the moral integrity of society successfully resists the wealth obtained from corruption, proving that social legitimacy cannot always be bought with money. Finally, "Sada al-Nisyan" criticizes the cycle of tyranny; the return of the main character's cruelty after amnesia proves that changes in individual behavior are meaningless without a transformation of the structure of the power arena itself. In conclusion, Mahfouz describes a social structure that is resistant to change, where the position of social agents is largely determined by the accumulation of symbolic capital and habitus that have been firmly institutionalized in society.

Abstract

This study aims to explain the use of illocutionary acts in the lyrics of the song Al-Mahkama performed by Kazim Al-Saher and Asma El Mnawar, which describes a dialogue of a couple of lovers who demand justice for their broken love relationship. The title Al-Mahkama is not merely a metaphor, but rather the main concept that forms the structure of the dialogue in the song, where love is seen as a matter to be judged, and language functions as a tool to assess, demand, and declare the truth. This study aims to identify the types and communicative functions of the illocutionary acts contained in the lyrics of the song. This research uses a qualitative descriptive method with song lyrics as primary data, while the analysis is based on Searle’s speech theory. The result of the research show that there are three types of illocution speech that are dominantly used, namely assertive (as statements and defenses), directive (as orders and requests for justice), and expressive (as emotional expressions). These three findings represent a concrete manifestation of language that judges love, where every utterance functions as a judicial process. Language used not only to express feelings but also to judge, demand justice, and establish truth from each speaker's perspective. This research contributes to the development of pragmatic studies and expands linguistic research in the field of modern Arabic music.

Abstract

Background: Hyperglycemia induces excessive production of reactive oxygen species (ROS), leading to oxidative stress and lipid peroxidation characterized by increased malondialdehyde (MDA) levels. This study evaluated the effectiveness of butterfly pea flower nanoherbal formulated as alginate-based nanoparticles using the ionic gelation method in reducing blood glucose and MDA levels in hyperglycemic rats. Methodology: 25 male Wistar rats (Rattus norvegicus) were divided into five groups: normal control (NC), metformin control (MC), and three nanoherbal treatment groups (NT1, NT2, and NT3) receiving doses of 12.5, 25, and 50 mg/kg body weight (BW), respectively. Hyperglycemia was induced by a single intraperitoneal injection of alloxan monohydrate (125 mg/kg BW). Blood glucose was measured on days 1, 14, and 28, while MDA levels were analyzed on day 28 using the TBARS method. The analysis of blood glucose levels was conducted using a Repeated Measures Two-Way ANOVA followed by a Bonferroni post hoc test, while MDA data were evaluated through a One-Way ANOVA with Duncan’s multiple range test (p < 0.05). Findings: A significant, dose-dependent reduction in blood glucose levels was observed following nanoherbal treatment. The NT3 group (50 mg/kg BW) showed the greatest reduction, with mean glucose decreasing from 471.4 ± 142.00 mg/dL on day 1 to 146.4 ± 68.58 mg/dL on day 28. MDA levels also differed significantly, with NT3 showing 2.84 ± 0.19 nmol/mL, indicating lower oxidative stress. Contributions: These findings indicate that alginate-based butterfly pea nanoherbal can reduce blood glucose and MDA levels in hyperglycemic rats, suggesting its potential role in improving glycemic control and reducing oxidative stress under hyperglycemic conditions
