Abstract

Bronkopneumonia merupakan peradangan pada parenkim paru yang sering kali menjadi penyebab mortalitas tertinggi di kalangan anak dan balita. Karya Tulis Ilmiah ini bertujuan untuk melaksanakan asuhan keperawatan anak yang komprehensif pada An. H (8 tahun) dengan diagnosis medis bronkopneumonia di Ruang Anggrek I RSUD dr. Soeselo Kabupaten Tegal. Metode yang digunakan adalah studi kasus deskriptif dengan pendekatan proses keperawatan sistematis melalui wawancara, observasi, pemeriksaan fisik, serta studi dokumentasi. Hasil pengkajian menunjukkan pasien mengalami sesak napas, demam naik turun, batuk dan pilek sejak tiga hari, penurunan nafsu makan, terdapat retraksi dada, suara napas tambahan ronchi, mukosa mulut kering, serta tanda-tanda vital berupa nadi 140 x/menit, RR 40 x/menit, dan suhu 38,3°C. Diagnosis keperawatan yang ditegakkan meliputi bersihan jalan napas tidak efektif berhubungan dengan hipersekresi jalan napas, hipertermia berhubungan dengan proses penyakit (infeksi), serta ansietas berhubungan dengan krisis situasional. Intervensi keperawatan difokuskan pada pemantauan respirasi, fisioterapi dada, pengaturan posisi semi-Fowler, pemberian minum hangat, manajemen cairan, serta kolaborasi obat antibiotik, antipiretik, dan terapi nebulizer. Selain terapi medis kolaboratif, perawat juga menerapkan intervensi non-farmakologis berupa terapi relaksasi menggambar untuk mengurangi kecemasan anak. Evaluasi keperawatan setelah pengelolaan selama tiga hari menunjukkan hasil yang optimal; bersihan jalan napas menjadi efektif, suhu tubuh normal kembali mencapai 36,5°C, dan ansietas teratasi ditandai dengan anak yang tampak lebih tenang serta kooperatif. Kesimpulannya, penerapan asuhan keperawatan anak yang sistematis, kolaboratif, dan komprehensif terbukti efektif dalam mengoptimalkan kepatenan jalan napas, mengatasi hipertermia akibat infeksi, serta meminimalkan kecemasan akibat hospitalisasi pada pasien anak

Abstract

Hantavirus infection remains a global health problem due to its high mortality rate and the lack of specific antiviral therapies. Sin Nombre Virus (SNV) is one of the most pathogenic hantavirus species, causing Hantavirus Cardiopulmonary Syndrome (HCPS) characterized by severe respiratory failure and high fatality rates. The nucleocapsid protein (NP) plays a critical role in the viral life cycle, making it a potential target for inhibitor development. This study aimed to evaluate the potential of dithymoquinone (DTQ) and ten of its derivatives as inhibitors of SNV nucleocapsid protein through an in silico approach. Molecular docking analysis was employed to predict binding affinity and molecular interaction patterns between ligands and the target protein (PDB ID: 5E05). The results showed that DTQ10 (with -NH-C₆H₄-COOH substituent) exhibited the best total grid score (-55.14 kcal/mol), supported by its larger molecular size and higher molecular weight, which enhance van der Waals interactions. Meanwhile, DTQ08 (with -NH-C₆H₅ substituent) demonstrated the best grid electrostatic (-5.61 kcal/mol) with a competitive total grid score (-49.96 kcal/mol), making it a superior candidate due to its strong polar interaction stability. These findings suggest that DTQ derivatives, particularly DTQ08 and DTQ10, have promising potential as inhibitors against the nucleocapsid protein of Sin Nombre Virus and warrant further investigation through in vitro and in vivo studies.

Abstract

Penelitian ini bertujuan untuk menganalisis perlindungan hukum terhadap pekerja yang menjadi korban Pemutusan Hubungan Kerja (PHK) massal akibat kebijakan penghentian operasional perusahaan, dengan fokus studi kasus pada PT Toba Pulp Lestari. Menggunakan metode penelitian hukum normatif dengan pendekatan kualitatif, kajian ini mengevaluasi kesesuaian pelaksanaan PHK massal dengan regulasi ketenagakerjaan di Indonesia, khususnya UU No. 13 Tahun 2003 sebagaimana telah diubah dengan UU No. 6 Tahun 2023 tentang Cipta Kerja. Hasil penelitian menunjukkan adanya kesenjangan yang signifikan antara norma hukum positif dan implementasi di lapangan. PHK massal sering kali dilakukan secara sepihak dengan dalih efisiensi tanpa melalui tahapan prosedural wajib seperti perundingan bipartit. Selain itu, tanggung jawab perusahaan dalam memenuhi hak normatif pekerja kerap mengalami keterlambatan atau pemotongan. Peran negara melalui fungsi pengawasan dan penegakan hukum juga dinilai belum optimal akibat keterbatasan kapasitas pengawas dan kompleksitas birokrasi peradilan hubungan industrial. Penelitian ini merekomendasikan penguatan pengawasan sanksi oleh pemerintah, peningkatan transparansi korporasi, serta penyederhanaan akses keadilan bagi pekerja.

Abstract

Pronunciation plays a crucial role in achieving intelligibility and communicative competence in English as a Foreign Language (EFL) contexts. However, Indonesian learners frequently experience difficulties in producing certain English sounds due to substantial differences between Indonesian and English phonological systems. This study aims to identify the most common phonological errors made by Indonesian learners in English pronunciation and to examine the factors contributing to these errors. Employing a qualitative literature review design, this study synthesizes findings from previous research published between 2020 and 2025 concerning pronunciation difficulties among Indonesian EFL learners. Relevant studies were collected through academic databases and analyzed using thematic analysis to identify recurring error patterns, underlying causes, and research trends. The findings reveal that the most frequent phonological errors involve the substitution of the English consonants /θ/, /ð/, and /v/ with more familiar Indonesian sounds. These errors are primarily influenced by first language interference, articulatory difficulty, limited exposure to authentic pronunciation models, and insufficient pronunciation-focused instruction. The review also highlights a significant imbalance in the existing literature, which predominantly focuses on segmental pronunciation errors while providing limited attention to suprasegmental features such as stress, rhythm, and intonation. This study contributes to the field by synthesizing fragmented findings, identifying research gaps, and emphasizing the need for more comprehensive pronunciation instruction in Indonesian EFL contexts. The findings are expected to provide valuable insights for researchers, language educators, and curriculum developers seeking to improve pronunciation teaching and learning outcomes.

Abstract

Pronunciation is an essential component of language learning because it influences intelligibility and communication effectiveness. One important feature of English pronunciation is aspiration, which occurs in the voiceless stop consonants /p/, /t/, and /k/ under specific phonological conditions. This study aims to analyze how UINSU students produce aspirated allophones in English pronunciation and identify factors influencing their production. This research employed a qualitative descriptive approach involving three students from the English Education Study Program at UINSU. Data were collected through interviews and voice-note recordings. The findings indicate that students generally understand the concept of aspiration and can apply it in appropriate phonological environments. However, their production remains inconsistent, particularly during spontaneous speech. Several factors influencing students’ pronunciation include first-language transfer, limited pronunciation practice, phonological awareness, and classroom instruction. The study concludes that although students have developed awareness of English aspiration, more explicit pronunciation training is necessary to achieve consistent and accurate production.

Abstract

English phonology is an important subject in the English Education Department because it helps students understand the sound system of the English language. Through the study of phonology, students learn about speech sounds, phonetic symbols, stress, and intonation. However, many students still encounter difficulties in learning English phonology due to the complexity of its concepts and the differences between English and their first language. This study aims to identify the difficulties experienced by fourth-semester students of the English Education Department in learning English phonology and to explore the factors that contribute to those difficulties. This study employs a descriptive qualitative approach. The participants are fourth-semester students of the English Education Department who have taken phonology-related courses. Data are collected through questionnaires and interviews to obtain information about students' learning experiences. The findings are expected to show that students face difficulties in understanding phonetic transcription, distinguishing English speech sounds, applying stress and intonation patterns, and pronouncing unfamiliar sounds. In addition, factors such as limited practice, lack of confidence, and first-language influence may contribute to these difficulties. The results of this study are expected to provide useful information for lecturers and students in improving the teaching and learning process of English phonology.

Abstract

The purpose of this study is to see how regional dialects and accents affect the phonological ability of EFL (English as a Foreign Language) students in Indonesia. The background of this research lies in the sociolinguistic situation in Indonesia where students usually master the regional language as their first language before starting to learn English. Phonological interference, which impacts students' pronunciation abilities, can be caused by differences in phonological systems between the first language and English. The focus of this study was to find the types of phonological aberrations in students' English pronunciation. Data were obtained through observation of pronunciation, documentation of speech results, and analysis of the form of sound realization of EFL students. Data analysis was carried out by data reduction methods, phonological error classification, interpretation, and conclusion drawn. The results showed that regional accents and dialects had a significant effect on students' phonological abilities. Sound substitution (sound substitution), phonological simplification (phonological simplification), epenthesis (addition of sounds), final consonant removal (final consonant removal), and orthographic impact on pronunciation are some of the major forms of phonological error. The primary cause of these errors is first language (L1) interference, specifically the structural and phonotactic differences between the students' native regional languages and the English phonological system. According to this study, the goal of learning pronunciation is not to eliminate accents, but to improve a person's comprehension so that they can communicate well in English.

Abstract

Persiapan bahan baku merupakan tahapan krusial dalam operasional dapur yang memengaruhi efisiensi produksi, keamanan pangan, dan kualitas produk akhir. Penelitian ini menganalisis sistem persiapan bahan baku di bagian dimsum Xiang Fu Hai Kitchen, Vasa Hotel Surabaya, yang meliputi proses thawing, trimming, pemotongan, pemberian bumbu, dan penyimpanan sementara. Penelitian menggunakan pendekatan kualitatif deskriptif, dengan data dikumpulkan melalui wawancara terhadap tiga juru masak, observasi lapangan, dan dokumentasi. Hasil penelitian menunjukkan bahwa metode thawing yang digunakan adalah chiller thawing, yang telah sesuai dengan standar keamanan pangan; namun, metode alternatif menggunakan air mengalir belum memiliki kontrol suhu dan waktu, sehingga menunjukkan adanya kesenjangan antara prosedur standar dan praktik harian. Proses trimming hanya dilakukan pada daging, yaitu dengan menghilangkan lemak dan silverskin, sementara seafood dan unggas diterima dalam kondisi bersih dan terfilet, sehingga mengurangi beban kerja pada tahap ini namun meningkatkan ketergantungan pada kualitas pemasok. Proses pemotongan menerapkan ukuran dan jenis potongan yang terstandardisasi, dengan sistem color-coding yang digunakan untuk mencegah kontaminasi silang antar kategori bahan. Proses pemberian bumbu mengikuti resep standar, menggunakan mixer untuk memastikan distribusi yang merata, dengan waktu marinasi yang bervariasi sesuai jenis bahan. Penyimpanan sementara dilakukan pada suhu chiller 1–5°C dan suhu freezer maksimal -17°C, dengan menerapkan sistem FIFO/FEFO serta pelabelan; namun, masih ditemukan berbagai jenis bahan yang disimpan bersama dalam satu wadah atau rak yang sama, sehingga berisiko menimbulkan kontaminasi silang. Secara keseluruhan, sistem persiapan bahan baku di bagian dimsum menunjukkan inkonsistensi antara standar operasional prosedur dan implementasinya di lapangan. Pemahaman, pelatihan, dan pengawasan lebih lanjut diperlukan agar proses tersebut memenuhi standar industri dan meminimalkan risiko keamanan pangan.
