Abstract

This research aims to create a walking bipedal robot with center of pressure feedback simulation for the center of mass learning, describe its feasibility for learning, describe students' motivation to learn, and describe students' science literacy after using it. The research method used ADDIE (analysis, design, development, implementation, and evaluation). The research data was obtained using a motivation scale questionnaire, science literacy scale, and feasibility scale. The research sample was 48 people; after the research obtained, the simulation of bipedal robot pressure center feedback for center of mass learning can be implemented with the principle of the robot's center of mass detected on the sole of the robot's foot equipped with a force sensitive resistor (FSR) sensor, the position of the center of mass is visible on the monitor screen as a center of mass learning, so that it can motivate students to learn and improve students' science literacy. This can be seen from the feasibility scale score, motivation scale, and science literacy scale of 4.133, 4.072, and 4.067 (scale 1 to 5), respectively, in the "good" category.

Abstract

Ambiguity is prone to occur in conversation. When communicating, the possibility of misunderstandings occurs due to unclear intentions or the existence of double meanings in the words and sentences used. Misunderstanding when communicating can occur at the phonetic, grammatical and lexical levels. This research method uses a descriptive method with a qualitative approach. Data were obtained by interviewing and recording conversations of Bengkulu University students. Recorded data was obtained from 36 informants. Then the data is transcribed and then classified. After being classified, the data were analyzed using ambiguity theory. Finally, conclusions are drawn. In this study, the misunderstandings found in student conversations occurred at the grammatical and lexical level. An understanding of semantics, especially ambiguity theory, needs to be mastered by both educators and students in order to overcome and resolve misunderstandings in conversation.

Abstract

This research aims to i) implement the solar cell based power-bank prototype for learning media; ii) describe the feasibility of the solar cell-based power-bank prototype for learning; and iii) describe students' scientific literacy. This research method uses the analysis, design, development, implementation, and evaluation (ADDIE) research and development model. The subjects of this research are class IX students and science teachers at SMPN 4 Central Bengkulu. Data collection techniques include questionnaires, tests, and interviews. The data analysis technique uses N-gain analysis, percentages, and the Aiken's V formula. The research results show that the media developed is valid with an Aiken index value of 0.98 > the minimum standard Aiken' V of 0.92 and can increase students' scientific literacy based on an N-gain of 0.92. 0.71, this can be seen in the dimensions of context and content based on N-gain of 0.73 and 0.69, while the dimensions of attitude, curiosity, respect, and willingness, reflect the respective percentages of 79.62%, 78.86%, 78.89%, 75.60%. Based on the results of the hypothesis test, the sig value is obtained. (2 tailed) 0.000 < 0.05 which means Ha is accepted and Ho is rejected, which means the solar cell-based renewable energy media used in science learning influences the increase in students' scientific literacy.

Abstract

This research aims to: 1) Produce a prototype design for a solar cell-based automatic garden lighting system; 2) Determine the relationship between current, power, and voltage and light intensity; 3) Describe the feasibility of an environmentally friendly technology practicum guidebook; and 4) Describe teacher and student responses to the environmentally friendly technology practice guidebook. This research is R&D type Analysis, Design, Development, Implementation and Evaluation (ADDIE) Analysis, design, development, implementation and evaluation. The research sample used 44 class IX students at MTS Rahmatullah. According to students, aspects of teaching materials, aspects of content, and difficulty of teaching materials at school are inadequate at 84.25%, 80% and 82.5%. Student interest in environmentally friendly technology practicum guidebooks was 84.25%. The higher the light intensity, the higher the current, power, and voltage. Expert validation shows; the prototype of an automatic garden lighting system based on solar cells and a practical guidebook on environmentally friendly technology are very suitable for use (89.14% and 90.75%). The use of environmentally friendly technology practicum guidebooks increased students' critical thinking skills in the high category (N-Gain = 0.7937) and received responses from teachers and students in the "almost all" category (91.50% and 89.9%).

Abstract

Penguatan literasi melalui pengajaran membaca pada mata kuliah pembelajaran sastra di perguruan tinggi. Literasi yang kuat sangat penting untuk mendukung kemampuan akademik dan keterampilan kritis mahasiswa, khususnya dalam memahami teks sastra. Pembelajaran sastra di perguruan tinggi tidak hanya berfokus pada pengenalan karya sastra, tetapi juga pada pengembangan kemampuan mahasiswa untuk menganalisis, menginterpretasi, dan mengkritisi teks sastra secara mendalam. Melalui pengajaran membaca yang berbasis pada teks sastra, mahasiswa diharapkan dapat meningkatkan keterampilan literasi mereka, baik dalam hal pemahaman bacaan, penalaran kritis, maupun kemampuan untuk menyampaikan pendapat secara sistematis. Penelitian ini mengkaji berbagai strategi pengajaran membaca yang dapat diterapkan dalam mata kuliah pembelajaran sastra, termasuk teknik membaca kritis, diskusi kelompok, dan penerapan teori sastra dalam konteks pendidikan tinggi. Hasilnya menunjukkan bahwa pengajaran yang efektif dapat memperkuat literasi mahasiswa, mendukung pengembangan kemampuan berpikir kritis, dan mempersiapkan mereka untuk berpartisipasi aktif dalam diskursus akademik. Dengan demikian, literasi menjadi salah satu pilar penting dalam pendidikan sastra yang dapat membekali mahasiswa dengan keterampilan yang berguna dalam berbagai bidang kehidupan.

Abstract

This study aims to evaluate the effectiveness of digital books in enhancing the early reading skills of children aged 5-6 years at PAUD IT Auladuna I, specifically within Group B, in 2024. The research employed a quantitative experimental method, utilizing a stratified random sampling technique to select a sample of 28 children from the entire population. Data were collected through documentation and observation, employing reading ability tests that assessed indicators such as reading independence, simple word recognition, comprehension, and pronunciation of vowels and consonants. The data analysis included normality and homogeneity tests, followed by a t-test to evaluate the hypothesis. The results indicated a significant positive effect of digital book usage on reading skill improvement, evidenced by a calculated tcount > ttable, namely 2,760 >1,691. These findings demonstrate that integrating digital books in educational settings can stimulate early reading development among young learners. Educators are encouraged to adopt digital media in their teaching practices to foster children's literacy. Furthermore, this research provides a foundation for future studies to investigate additional effective learning media that support literacy development.

Abstract

The purpose of this study was to develop learning media for Android-based Literary History using thunkable applications in the independent learning-free campus era. This study applied the Research and Development method whose products were tested on students. Therefore media validation and material validation are needed before it is finally validated by the user. Research data collection uses a questionnaire so that it is known about the feasibility of the product in the form of thunkable application-assisted learning media. This study concluded that the total score of the combined validation questionnaire was 129 or 4.03 as the average. In other words, these results state the feasibility of android-based modern Indonesian literature learning media assisted by the thunkable application for use in teaching and learning activities in Literary History courses.
