Abstract

The aims of the research were to develop instructional materials for science integrated with Islamic values, to determine the appropriateness and the effectiveness of the developed product for increasing learning output. Science learning output is consisting of attitude (religious attitudes and positive attitudes toward science) and learning achievement. This research is Research and Development (R&D) using the Borg & Gall model. Data analysis techniques using gain score, independent t-test, and MANOVA test. Instructional materials in the form of MTs student books and MTs teacher books. Product assessment of the MTs student books according to matter experts and media experts are categorized "very well". The MTs teacher books according to matter experts are categorized "good", and according to media experts are categorized "very well". Learning to use student books showed that religious attitudes had risen high (the mean gain score was 0.70), positive attitudes towards science had risen middle (the mean gain score was 0.57), and science learning achievement had risen middle (the mean gain score was 0.55). MANOVA test showed that Sig value is 0.00.

Abstract

This study is to provide valid, practical, and effective Android application-based interactive learning media for the Basics of Mechanical Engineering subject in class X Mechanical Engineering at SMK Dhuafa Padang. This medium is intended to boost students' comprehension, motivation, and independence, allowing them to achieve better learning outcomes. The research approach employed is Research and Development (R&D), using a 4D development model (define, design, develop and disseminate). The primary data utilized in this study came from validators, teachers, and students. Data was analyzed descriptively to characterize the validity, practicality and effectiveness of the learning media developed. The validity test findings show that this learning medium, which had a media aspect score of 0,892 and a material aspect score of 0,950, was deemed valid by expert review. This media was also declared practical with a practicality score of 96,94% from teacher responses and 92,25% from student responses. In the effectiveness test, the Gain Score was 0,68, placing it in the medium category. Meanwhile, the t-test shows a Sig value (2-tailed) of 0.002 (2-tailed < 0,05) and a tcount value of 3,372 (tcount ˃ ttable), indicating a significant difference in learning outcomes between students who use this learning media (experimental class) and those who do not use the media (control class). Thus, this Android application-based interactive learning media is declared valid, practical and effective for use in the DDTM learning process.

Abstract

The process of learning interactions between living things and the environment requires direct observation by students, but in reality the school is located in the city center with a less than optimal surrounding environment. The availability of learning media for this material has not been widely developed by students. The research aims to produce aquascape media that is suitable as an aid in learning interactions between living things and the environment to improve students' mastery of concepts and communication skills. The research uses a 4D development model which includes Define, Design, Develop, and Dessiminate. The test subjects were taken using a cluster random sampling technique and a sample of 66 students at SMPN 12 Yogyakarta was obtained, consisting of experimental and control classes. The field test used quasi-experimental research with a nonequivalent control group design. The feasibility, teacher practicality, and effectiveness of assessing aquascape media as an aid in learning interactions between living creatures and the developed environment are included in very good and practical.

Abstract

This study aims to identify the factors influencing environmental parameters in water and sediment and evaluate their impacts on ecosystems and biota, thereby providing a scientific basis for effective and sustainable water resource management. Measurements were conducted at 10 natural ecosystem locations comprising rivers, beaches, estuaries, and lakes in West Sumatra. The parameters measured in the water were temperature, pH, DO, and salinity, while in the sediment, pH, TOC, ammonium, nitrate, nitrite, phosphate, and sulfate were measured. The results of the environmental parameter analysis in the water were Temperature (26.3 ± 0.65°C), pH (7.62 ± 0.43), DO (4.5 ± 0.81 mg/L), and Salinity (13.78 ± 13.95 ppt). In the sediment, the results were pH (6.74 ± 0.86), TOC (1.49 ± 0.29%), Ammonium (12.95 ± 5.34 mg/L), Nitrite (76.33 ± 34.26 mg/L), Nitrate (31.60 ± 5.25 mg/L), Phosphate (29.5 ± 20.37 mg/L), and Sulfate (29.46 ± 8.23 mg/L). Overall, the factors affecting water and sediment parameters are biological activity, land input, and anthropogenic contaminants. The ability of sediment to accumulate and absorb particles and chemicals is one of the factors causing the high concentration of environmental parameters in sediment

Abstract

This research aims to produce a textbook based on the results of the research on the ability of bacteria to degrade heavy metals. The research was conducted using the ADDIE model with a series of tests such as a validity test, practicality test, and textbook effectiveness test. The textbook is validated by 3 experts: learning experts with a score of 91% (valid), materials experts with a score of 100% (valid), and practitioners with a score of 95% (valid). Practicality test using student responses from individual test (score 89%), small group test (score 90%), and field test (score of 89%). The effectiveness test of textbooks using an experimental method with a one-group pretest-posttest-only design by comparing the pretest and posttest scores using the Wilcoxon test and the N-Gain test. The Wilcoxon test results showed a significance value obtained smaller than 0.05 (p-value (0.000) < 0.05), this shows that there is a significant influence between the pretest and post-test scores. The N-Gain results were at a score of 0.4, which means that the improvement experienced by students was at a moderate level. Based on the validity, practicality, and effectiveness scores, it can be concluded that the textbooks are valid, practical, and effective.

Abstract

Glaucoma is one of the leading causes of permanent blindness and remains a current challenge in the field of ophthalmology. This research aims to present a comprehensive investigation into the development and evaluation of new technology for glaucoma detection in retinal fundus images. The development and evaluation are presented on a customized architecture, using the Convolutional Neural Network (CNN) method. The proposed CNN architecture is designed to address the complex characteristics of glaucoma changes in the identification process. The research dataset consists of 506 retinal images categorized into 117 glaucoma images, 19 suspected glaucoma images, and 370 healthy images. Through our in-depth exploration, we conducted a careful analysis to uncover patterns and fundamental trends related to glaucoma-related features. During the training phase, the proposed CNN achieved outstanding average accuracy, sensitivity, and specificity values of 92.88%, 94.66%, and 89.31%, respectively. In the unseen test dataset, the model demonstrated competitive performance with an accuracy of 80.87%, sensitivity of 85.65%, and specificity of 71.26%. These findings emphasize the potential of the model as a reliable tool for glaucoma detection. The results indicate that the proposed method utilizing a customized CNN architecture is designed for glaucoma detection in retinal fundus images. The presented output results also hold promise for clinical relevance and can be considered an improvement in the care of retinal fundus patients.
