Abstract

Kegiatan magang di Grand Mercure Jakarta Kemayoran berfokus pada pengolahan bahan makanan untuk mencapai pengurangan food waste hingga 30 %. Melalui tinjauan literatur dan analisis berbagai naskah terkait, diidentifikasikan faktor-faktor utama yang menyebabkan pemborosan makanan, seperti perencanaan yang buruk, pemborosan makanan di dapur, ukuran porsi yang berlebihan, dan pengendalian inventaris yang tidak memadai. Penelitian ini menyoroti pentingnya perencanaan yang matang dalam pembelian bahan makanan, pengelolaan inventaris yang efisien, praktik kebersihan yang benar di dapur, dan kesadaran akan ukuran porsi yang realistis. Selain itu, strategi penggunaan kembali sisa-sisa makanan dan pengolahan kembali bahan makanan yang tidak terpakai juga menjadi fokus penting dalam mengurangi pemborosan makanan. Hasil analisis menunjukkan bahwa penerapan praktik-praktik efisien dalam pengelolaan bahan makanan hewani dapat menghasilkan dampak positif, seperti pengurangan pemborosan makanan, peningkatan efisiensi operasional, dan penghematan biaya. Diperlukan kesadaran dan tindakan yang lebih proaktif dalam pengelolaan bahan makanan, baik dari segi perencanaan, penggunaan, maupun pengolahan kembali sisa-sisa makanan. Dengan demikian, peserta magang mendapatkan edukasi dan memberikan kontribusi dalam upaya mengurangi dampak negatif terhadap lingkungan akibat pemborosan makanan serta meningkatkan efisiensi dan keberlanjutan sektor pangan dalam industri perhotelan.

Abstract

Phonology plays a crucial role in second language acquisition, particularly in enhancing pronunciation, listening comprehension, and overall communicative competence. This study explores the role of phonology in English language learning among Indonesian EFL (English as a Foreign Language) students. Using a qualitative descriptive approach, data were collected through semi-structured interviews with twelve university students majoring in English Education. Findings reveal that learners often struggle with English sounds that do not exist in their first language, such as /?/ in think, which impacts pronunciation and listening. Although phonological instruction was limited, students expressed a strong belief in its importance and advocated for more explicit teaching of sound systems. The study suggests the integration of phonology-focused strategies in EFL curricula to support learners’ oral proficiency.

Abstract

English language instruction places a high priority on syntax, notably in assisting pupils in comprehending grammatical relationships and sentence structure. Predicate identification and syntax tree creation, both of which demonstrate students' comprehension of hierarchical sentence structures, are two crucial aspects of syntax learning. This study seeks to determine how well students comprehend predicate identification and syntax tree creation in English syntax. Students in the English Department who had finished a syntax course participated in a quantitative descriptive study design. The data were gathered via an internet survey that included Likert scale questions and multiple-choice options. The data were then analyzed using descriptive statistics presented as percentages. According to the data, the majority of students exhibit a strong conceptual grasp of predicates, as seen by their capacity to recognize predicates in basic sentences and identify verbs as the head of verb phrases. But in analyzing complex sentence structures and building syntax trees, students exhibit less assurance and skill. Despite these challenges, students show a positive outlook on learning syntax and a strong desire to increase their knowledge. The research comes to the conclusion that, despite students having basic syntactic knowledge, more instructional focus should be placed on visual-based methods and guided practice in order to improve their practical skills in creating syntax trees.

Abstract

In English as a Foreign Language (EFL) writing, grammar is essential for achieving precision and clarity, particularly when it comes to creating questions. The subject and auxiliary verb must be reversed in yes/no and wh-questions, according to the necessary grammatical form known as subject-auxiliary inversion (SAI). Using a descriptive quantitative methodology, this study seeks to analyze the frequency and patterns of SAI mistakes in the writing of EFL learners. Twenty-two undergraduate EFL students from the State Islamic University of North Sumatra (UINSU) from various academic semesters made up the participants. Using a structured grammar test modified from Azar (2009) and administered electronically using Google Forms, data were collected. The frequency and kinds of inversion mistakes were determined using descriptive statistics and error analysis in the analysis. The results demonstrate that SAI is utilized with a very high overall accuracy rate (over 95%), suggesting that the majority of students have fully absorbed this grammatical principle. Nevertheless, there were still some little mistakes, especially in statements using present simple, past simple, and present perfect auxiliary verbs. Although formal grammar teaching is generally successful, these findings indicate that there is still a need for focused reinforcement on tense-auxiliary alignment. By highlighting the significance of targeted remedial grammar exercises in improving grammatical precision in writing, the research offers practical pedagogical recommendations for EFL teaching.
