The Effect of Teaching Games for Understanding (TGfU) Learning Model on Improving Students' Social and Cognitive Skills in Physical Education at SMK Merdeka Bandung
No full textThis study aims to analyze the effect of the Teaching Games for Understanding (TGFU) learning model on improving students' social and cognitive skills in physical education. This study uses a quasi-experimental design with control and experimental groups that were given pre-tests and post-tests. The research sample consisted of 50 students in grade XI at SMK Merdeka Bandung who were randomly selected from existing classes. The experimental group received treatment using the TGFU model, while the control group followed conventional learning. The instruments used to measure social skills were the Social Skills Inventory (SSI), and to measure cognitive skills, the Game Performance Assessment Instrument (GPAI) test was used. The results of data analysis using an independent t-test showed that there were significant differences between the experimental group and the control group on both variables, namely social skills with a significance value of 0.040 and cognitive skills with a significance value of 0.000. These findings indicate that the application of the TGFU model can significantly improve students' social and cognitive skills, so that it can be implemented as an effective approach in physical education learning. Random assignment was carried out within predetermined class boundaries; however, this quasi-experimental design still provides a valid picture of the influence of the TGFU model
Pengaruh pemberian pakan pellet dengan level yang berbeda terhadap pertambahan bobot badan harian dan konversi ransum domba
No full textThis study aimed to evaluate the effect of feed treatments on Average Daily Gain (ADG) and feed conversion in rams. The sheep we used were 16 Fat Tail Sheep (FTS) with four treatments and four replications applied: P0 (ad libitum field grass hay as control); P1 (P0 + pellets 0.5% of body weight); P2 (P0 + pellets 1% of body weight); and P3 (P0 + pellets 1.5% of body weight). The parameters observed were average daily gain and feed conversion, and the data were analyzed by ANOVA and further tested using Duncan Multiple Range Test (DMRT) at a 95% confidence level. The results showed that a significant difference (p<0.05) in average daily gain, with the best treatment in P3 at 52.81 g/head/day. Feed conversion also showed a significant difference (p<0.05) between the best treatments in P3, with the best treatment at 15.74. It can be concluded that the addition of pellets with a dose of 0.5% to 1.5% of body weight can increase average daily gain and feed conversion. Therefore, the use of local pellet feed has strong potential as an alternative fattening ration to optimise sheep production performance
Potensi Putak (Corypha utan Lamk) sebagai sumber pati lokal untuk binder wafer pakan: kajian literatur terhadap sifat kimia dan aplikasinya
No full textPutak (Corypha utan Lamk) is a locally abundant starch source in Eastern Indonesia with emerging potential as a functional binder for feed wafer production. This study aims to analyze the chemical properties of putak starch and its role as a binder in feed wafer production, and to compare it with other commonly used binding materials. The study was conducted using a descriptive approach based on various scientific publications obtained from the Scopus and Google Scholar databases using the keywords: “adhesive, Corypha utan, feed wafer, gelatinization, physical quality, putak, and binder”. This review summarizes current evidence on the chemical composition and techno-functional properties of putak starch in relation to binder performance requirements. Putak contains high carbohydrate levels (85–87%) and substantial starch content (64–67%), with an amylose–amylopectin ratio comparable to tapioca and sago. These characteristics support desirable functional behaviours, including gelatinisation ability. Comparative literature shows that starch-based binders consistently improve physical qualities, including wafer durability index (WDI), density, impact resistance, total solubility, and water absorption. Given its beneficial properties and local availability, putak represents a promising sustainable alternative to commercial starch binders. Further focused studies are needed to determine binding efficiency and storage stability

No full textSocio-Scientific Issues (SSI)-based learning has become increasingly significant in addressing global challenges, particularly for Generation Alpha, who are growing up in the digital era. This study aims to analyze the effectiveness of the SSI-based learning approach within the context of the Sustainable Development Goals (SDGs) at the elementary school level. A qualitative research approach with a case study design was employed, involving observations, interviews, and document analysis of educators and students from several elementary schools. The findings indicate that implementing SSI-based learning contributes to enhancing students' understanding of global issues while simultaneously strengthening critical thinking, problem-solving, and collaboration skills. Educators play a central role in designing interactive and technology-based learning strategies to increase student engagement. However, challenges remain in implementing this approach, including teachers' readiness and limited learning resources. Therefore, integrating SSI-based learning within the SDG framework in elementary education can be an effective strategy for improving students' scientific literacy and social awareness. Further research is needed to develop training strategies for educators and expand the implementation of this method across various educational contexts. In conclusion, integrating the SSI approach based on SDGs into science education in elementary schools has great potential to enhance scientific literacy, social awareness, and 21st-century skills among students
VIRTUAL REALITY-BASED MEDIA TO ENHANCE SUNDANESE DESCRIPTIVE WRITING SKILLS
No full textLearning to write Sundanese descriptive texts presents several challenges, particularly in the limited availability of engaging and contextualized learning media. Students often lack real-life experiences related to the objects they are asked to describe, and the absence of interactive media contributes to the low quality of their descriptive writing. This study aims to analyze the needs for Virtual Reality media to enhance students’ skills in writing Sundanese descriptive texts at the junior high school level. A descriptive qualitative method was employed in this research. The participants included 8 Sundanese language teachers and 145 junior high school students from Bandung City. Data were collected through questionnaires and interviews conducted during the 2024/2025 academic year. The collected data were analyzed using qualitative techniques involving data reduction, data display, and conclusion drawing. The results indicate that students’ ability to write Sundanese descriptive texts remains relatively low, primarily due to the lack of innovative and immersive learning media. Teachers also face challenges in providing learning experiences that allow students to observe or visualize descriptive objects directly. Virtual Reality shows potential as a promising solution, offering immersive, simulated environments that help students gain contextual understanding. These findings suggest that the development of Virtual Reality media is urgently needed to support students’ learning needs in writing Sundanese descriptive texts. Furthermore, this study serves as a foundation for future research focusing on the design and effectiveness of Virtual Reality-based learning media in enhancing descriptive writing skills in Sundanese language education
