Abstract

Limited laboratory equipment causes practicum of vertebrate animal organ systems to be rarely carried out so that learning is only theoretical and has an impact on student understanding that is less than optimal. This study aims to develop and test the validity and feasibility of an Android-based virtual laboratory with a starter experiment approach on vertebrate animal organ system material for high schools. This media is also equipped with LKP (Practicum Worksheet) to support virtual laboratory activities. This research uses the Research and Development (R&D) method with the ADDIE model. Data were collected through validation questionnaires from media experts, material experts, and trials to students, then analyzed descriptively, quantitatively, and qualitatively. The validation results show that the virtual laboratory has a validity level of 91% from media experts and 89% from material experts, which is included in the "very valid" category. Meanwhile, the feasibility test results showed a value of 91% in individual trials, 96% in small groups, and 94% in large groups, all of which were included in the "very feasible" category. Thus, the Android-based virtual laboratory with a starter experiment approach on vertebrate animal organ system material is very valid and feasible to use in learning. This media helps teachers deliver material, enhances student understanding, and addresses lab limitations in technology-based learning. Further development should optimize app size for low-spec devices, ensure compatibility with iOS, and improve interactive features for a more realistic practicum experience.

Abstract

Small and Medium Enterprises (SME) has important role in economic growth. Along with the advance development of information technology emerging new tools for promoting product which can be used by SME. Through Public Service, the Department of Informatics Education Universitas Trunojoyo Madura sees potential economic development for SME for using tools such as e-commerce and Marketplace which is could guide to the enhancement of social quality of women and women labor, especially in Madura. Through the Public Service, it could be concluded further development of the attendees to use and promote their SME’s product.

Abstract

Technology has been applied in various areas of life, including education. Technological advances provide students with more materials and lessons to help them learn more efficiently. One application that can be used to create e-learning modules that optimize digital media. In the Exe learning program, teachers can develop modules to add text, images, and videos and create multiple-choice questions. The development of learning media using the ADDIE model includes analysis, design, development, implementation, and evaluation, and it involves class X students of Computer Networks at SMKN 1 Sepulu as research subjects. Data was collected through observation, interviews and tests. Data analysis was carried out using descriptive and qualitative methods. Two expert validators, material experts and media experts, carried out the validation. The data collection technique uses a questionnaire. Validation results from material experts meet the requirements of 93%, which means they are very valid. The media expert results meet the requirements at 96%, which means they are valid. At the implementation stage, a trial was carried out. The results of field trials on 10th-grade Computer Network students showed that as many as 30 students obtained an average score of 92.6% with excellent qualifications, which means this media is easy for students to learn. The test results of EXE-based learning media show that the media is very suitable for use as a computer network learning medium and helps students in teaching and learning.

Abstract

Clustering is a technique for grouping homogeneous data so that the points in each cluster are as similar as possible according to convenience measures such as Euclidean-based distance or correlation-based distance. In the industrial era 4.0, learning media, the environment, the way teachers teach will affect student learning styles. From research on learning styles, many researchers agree on the importance of identifying learning styles to accelerate their learning performance. The purpose of this study is to classify student learning styles in the industrial era 4.0 using the Kmeans algorithm and the elbow method. The research method used is a waterfall. The number of research subjects was 108 students. the results of the research on the number of clusters (K), namely 6, obtained cluster 1 as many as 27 students, cluster 2 as many as 24 students, cluster 3 as many as 21 students, cluster 4 as many as 17 students, cluster 5 as many as 11 students and cluster 6 as many as 8 students. The performance of the grouping results based on the silhouette coefficient is 0.302, which means the grouping structure is weak. In cluster 1, the highest number has auditory elements, followed by kinesthetic and visual elements. The development of ICT-based media is one of the factors of student learning styles in the industrial era 4.0
