Abstract

Penelitian dalam pembelajaran bahasa Inggris merupakan suatu kegiatan ilmiah yang bertujuan untuk menyelidiki kaidah-kaidah yang berlaku dalam proses pembelajaran bahasa Inggris. Kegiatan penelitian dalam pembelajaran bahasa Inggris meliputi empat langkah: mengamati, mendeskripsikan, menganalisis, dan menjelaskan. Cara setiap langkah dilakukan bergantung pada sifat data dan tujuan penelitian. Penelitian Tindakan Kelas (PTK) untuk Pembelajaran Bahasa Inggris bertujuan untuk mengembangkan strategi pembelajaran tertentu untuk memecahkan masalah pembelajaran praktis di kelas bahasa Inggris. Setiap pembelajar bahasa Inggris pada dasarnya mampu belajar bahasa Inggris asalkan dia diberikan bantuan yang tepat karena setiap pembelajar memiliki gaya dan strategi belajarnya masing-masing. Penelitian Tindakan Kelas (PTK) bertujuan untuk menemukan strategi belajar-mengajar yang sesuai dengan gaya dan strategi pembelajar dalam belajar bahasa Inggris. PTK dilakukan dalam beberapa siklus yang masing-masing diulang pada siklus berikutnya apabila hasilnya belum memuaskan dengan revisi RPP yang lebih baik. Setiap siklus diawali dengan perencanaan pembelajaran, pelaksanaan rencana, observasi pelaksanaan, dan refleksi atau evaluasi proses dan hasil pelaksanaan. Hasil refleksi menentukan siklus berikutnya.

Abstract

In recent years, digital intelligence has developed significantly and plays an important role in the transformation of education. The research method conducted in this study is literature. The results show that advances in educational technology such as AI, VR, and the use of big data have provided innovative instruments to facilitate a learning process that is more of being split into autonomous and specialised. The adoption of these new tools seems to increase interaction and personalization in learning, providing opportunities for students to learn at their own time and pace. However, the literature also notes the challenges faced, including unequal access to technology, the need for infrastructure adaptation, and the demand for teacher capacity building. The results show that students who have complete and supportive access to digital intelligence show improvements in academic engagement and achievement.

Abstract

The development of digital technology has encouraged the emergence of adaptive learning technologies that allow personalized learning based on students' abilities and needs. This study aims to examine the development of adaptive learning technology and its implications on learning motivation and student learning outcomes through the library research method. Research data was obtained from various reputable scientific articles indexed by Scopus and other relevant academic sources, then analyzed using content analysis techniques to identify research trends, key findings, and research gaps related to adaptive learning. The results of the study show that adaptive learning technology has the potential to increase student engagement and learning motivation through the presentation of materials that are tailored to individual abilities. In addition, personalization of learning also contributes to improved learning outcomes when supported by appropriate pedagogic design and effective technology integration. However, the implementation of adaptive systems still faces challenges related to infrastructure readiness, educator competence, and user data protection aspects. Therefore, future development of adaptive learning will need to integrate technology, pedagogical strategies, and institutional support to create a more effective and sustainable learning experience.

Abstract

Double damper also known as a double flap damper, is a special control device used in the ash transfer system of a boiler before it enters the multi-cyclone. Mechanical testing (hardness and impact) is the most effective test for obtaining an overview of the mechanical properties of a material. Although hardness testing is only performed at a single point, or a specific area, the hardness value is quite valid in indicating the strength of a material. By conducting a hardness test, a material is easily classified as ductile or brittle. Impact testing is a test that uses rapid loading. In mechanical testing, there are differences in the type of load given to the material. Tensile testing, compression testing, and torsion testing are tests that use static loads. Meanwhile, impact testing uses dynamic loads. In rapid loading, also known as impact loading, a large energy absorption process occurs from the kinetic energy of a load that impacts the specimen. This energy absorption process will be converted into various responses in the material such as plastic deformation, isterisis effects, friction, and inertia effects. The purpose of this study is to determine the hardness value of the Double Dampers Valve Plate and to determine the strength of the Double Dampers Valve Plate through the impact test method. The test results obtained the hardness value of test material 1 (0°C) = 111.3 HRC, test material 2 (25°C) = 108.033 HRC, and test material 3 (100°C) = 103.9 HRC. In the impact test, the results of the impact strength analysis of test material 1 (0oC) = 0.215 Kg.m/mm2, test material 2 (25°C) =0.235 Kg.m/mm2, and test material 3 (100°C)= 0.255 Kg.m/mm2.

Abstract

The implementation of Outcome-Based Education (OBE) in Indonesian higher education has reshaped English language learning, yet systematic evaluation of its effectiveness remains limited. This research addresses the urgent need to evaluate whether OBE-based English instruction achieves intended learning outcomes, given persistent gaps between curriculum design and classroom practice. The objective of this study is to evaluate OBE-based English language learning in higher education, specifically examining outcome achievement, curriculum-practice alignment, implementation challenges, and stakeholder perception consistency. A qualitative evaluative approach was employed, involving semi-structured interviews with six English instructors, focus group discussions with fifteen students across proficiency levels, classroom observations of twenty sessions, and document analysis of course syllabi and OBE policy documents. Thematic analysis revealed four main findings: OBE learning outcomes are partially achieved, with writing outcomes significantly lower than speaking and listening; substantial misalignment exists between OBE curriculum documents and practice, with teacher-centered instruction dominating 70% of observed sessions; multidimensional challenges including resource limitations, pedagogical difficulties, and cultural factors constrain implementation; and instructors systematically overestimate student outcome attainment compared to student self-assessments. The study concludes that OBE-based English learning requires targeted writing interventions, instructor professional development in authentic assessment design, technology infrastructure investment, multi-stakeholder evaluation mechanisms, and cultural adaptation strategies. Further longitudinal and comparative studies across institutions are recommended.

Abstract

Indonesia secara tegas menyatakan bahwa Pancasila merupakan ideologi dan dasar negara. Hal mengandung konseksuensi logis dan etis bahwa semua permasalahan hendaknya ditafsirkan dan diputuskan sesuai dengan nilai, norma, dan kaidah Pancasila termasuk LGBT.Penelitian ini bertujuan untuk mengkaji cara pemaknaan Pancasila menurut beberapa tokoh khususnya Notanogoro dan dikaitkan dengan Fenomena LGBT. Kajian ini menemukan bahwa perbedaan sudut pandang LGBT di Indonesia lebih disebabkan perbedaan penafsiran atas sila Pancasila. Penelitian ini menggunakan pendekatan kualitatif dengan metode pengumpulan data kajian literatur (library research) dengan menggunakan sumber buku, jurnal, dan sumber lainnya yang relevan. Data diolah melalui empat tahapan yakni pengumpulan data, reduksi data, penyajian dan penarikan kesimpulan Model Habermas dan Miles. Penelitian ini menemukan bahwa Pancasila menurut Notanogoro idealnya ditafsirkan secara hirarki-piramidal. Hal ini juga senada dengan pendapat Kaelan. Penelitian masih sangat terbatas baik dari segi kedalaman kajian dan sumber referensi. Oleh karena itu sangat diperlukan riset dengan pendekatan berbeda dan kajian yang lebih mendalam

Abstract

The Combustion chamber door is a component of the boiler that functions to open and close the combustion chamber. At PT. XYZ, the combustion chamber door is made through the melting and metal casting method. In the metal casting method using a sand mold, an auxiliary substance in the form of bentonite is needed which functions to glue the sand mold and strengthen the mold so that it is not easily destroyed when receiving heat from the molten metal lava. The bentonite variations used in this study are 8%, 10%, and 12%. Mechanical testing (impact and hardness) is the most effective test to determine the description of the mechanical properties of a material. The purpose of this study is to determine the magnitude of the impact strength of the metal casting results in the manufacture of combustion chamber doors with different bentonite variations impact testing with the Charpy Impact Test method and the hardness value of the metal casting results in the manufacture of combustion chamber doors with different bentonite variations through hardness testing with the Rockwell Hardness Test method. In the impact test, the results of the impact strength analysis of the 8% bentonite variation were 0.1655 Kg.m/mm2, the 10% bentonite variation was 0.2119 Kg.m/mm2, and the 12% bentonite variation was 0.2555 Kg.m/mm2. In the hardness test, the results of the hardness analysis on the 8% bentonite variation were 104,7 HRC, the 10% bentonite variation was 92,1 HRC, and the 12% bentonite variation was 81,8 HRC.
