Abstract

Penggunaan bahan bakar fosil pada kendaraan bermotor telah menjadi salah satu penyumbang utama emisi gas buang yang berdampak buruk bagi lingkungan. Penelitian ini bertujuan untuk mengkaji efektivitas penggunaan zeolit sebagai filter untuk menurunkan kadar emisi gas buang pada sepeda motor. Uji eksperimental dilakukan pada Yamaha Jupiter tahun 2010 dengan variasi putaran mesin (RPM) 1000, 2000, dan 3000. Hasil uji menunjukkan bahwa zeolit mampu mengurangi konsentrasi karbon monoksida (CO), hidrokarbon (HC), dan nitrogen oksida (NOx) secara signifikan pada berbagai tingkat RPM. Zeolit bekerja efektif dalam menyerap polutan gas buang karena struktur pori-porinya yang khas dan kapasitas adsorpsi yang tinggi. Grafik hasil uji menunjukkan penurunan emisi yang lebih signifikan pada RPM tinggi. Penelitian ini diharapkan dapat memberikan kontribusi dalam pengembangan teknologi filter ramah lingkungan yang aplikatif untuk kendaraan bermotor di masa depan. .

Abstract

This study tackles a critical challenge in converting two-dimensional (2D) images into three-dimensional (3D) representations, focusing on the precise detection of flat surfaces. The research utilizes a triangulation method involving laser and camera systems, emphasizing the optimization of laser shooting angles and camera positioning to accurately determine z-coordinates. The methodology employs hue, saturation, and value (HSV) color masking, which has proven superior to traditional red, green, blue (RGB) methods for isolating red line objects. Key findings indicate that the optimal laser angle, β1=70.65°, significantly minimizes root mean square (RMS) error, thereby enhancing the accuracy of 3D imaging. Additionally, the use of three laser lines at different angles enables a more comprehensive detection of z-coordinates by creating multiple reference points across the surface. This arrangement improves the robustness and precision of the 3D reconstruction process, as the intersecting laser lines generate detailed coordinate data that is critical for accurately mapping surface irregularities. These results not only support existing theories in digital feature extraction but also offer a robust framework for practical applications in manufacturing and quality control, particularly in surface defect detection. The study’s innovative approach advances the field of computer vision, providing new insights and methodologies for optimizing image conversion techniques.

Abstract

The objective of this study is to evaluate the effectiveness of teachers in implementing pedagogical skills. The present study used a mixed methods approach. The participants in this study consisted of 55 highly effective educators employed in vocational secondary schools. The research data were acquired using effective teacher questionnaires, peer evaluations, observations, and comprehensive interviews. The findings indicated that a majority of highly effective educators possess a strong comprehension of the practical application of pedagogical competence. Nevertheless, a marginal disparity exists between academic knowledge and its practical application in the respective domain. The facilitation and support of teachers in the development of their pedagogic competences is a crucial responsibility of school principals. Effective and well-structured ongoing training is essential to bridge the divide between theoretical concepts and practical application, and to guarantee that educators possess the requisite expertise and understanding to tackle the demands of the current and future educational landscape. Hence, it is imperative to allocate resources towards teacher professional development and ensure the availability of sufficient assets in vocational secondary schools in order to attain educational excellence in Indonesia.

Abstract

Maeswara Basket faces problems with manual flattening tools that are ineffective in producing crafts from water hyacinth fibre. The proposed solution is developing a flattening tool by considering ergonomics, work safety, speed settings, and primary controls features. This study uses a community-based research (CBR) approach with five stages: problem identification, literature analysis, design planning, manufacturing, and evaluation. Six people assessed the flattening tool based on ease of use, process efficiency, quality of results, and overall evaluation using a Likert scale of 1-5. The results showed that the tool met important criteria such as ergonomics, ease of operation, flattening speed, thickness consistency, quality of results, and component durability, with scores ranging from 4.3 to 4.8 out of 5.0, categorized as "very satisfactory." The new tool excels in ease of use, process efficiency, and quality of results, with the main features of speed settings and controls that maintain the stability of fibre size during the flattening process. This study contributes to the development of products according to community needs. It has the potential to increase the production capacity of water hyacinth artisans, with opportunities for further development using automation technology.

Abstract

The unavailability of interactive media, namely e-module, has an impact on students so that they tend to be passive and less interested in learning in clinical dietetics subjects, resulting in student learning outcomes that are not by competency standards. This study aims to develop and prove the feasibility of e-modules in nutrition science and explore the importance of developing e-modules to improve learning achievement. This study is a Research and Development (R&D) using a 4-D model with a quantitative approach. The subjects of this study were students of class X majoring in culinary, which amounted to 124 respondents. The data collection technique used interviews and questionnaires that were used to validate and prove the results of the e-module feasibility. The results of material expert validation show that the e-module is very feasible to use with a percentage of 91.250%, media experts contribute to media eligibility 91.875%, while student assessments get 86.618% eligibility. So that the clinical dietetics e-module is feasible to be used as learning. Parametric statistics with comparative analysis of two samples using the T-test, Dunnet-C, and Tukey's test were conducted to determine differences in the variables of gender, age, and class. Comparative analysis proves that there is no significant difference between class X students in assessing the development of nutrition science e-modules. The existence of a clinical dietetics e-module can make it easier for students to learn and carry out learning independently so that student learning outcomes are according to competence.
