Abstract

Environmental education is one of the important aspects of Higher Order Thinking Skills (HOTS)-based elementary school learning. The use of learning media for e-learning implementation requires HOTS-based evaluation. This study aims to perform analysis related to HOTS and the utilization of e-learning in elementary school (SD). The method used in the research is the descriptive method with a survey as the data collection technique. The research instrument is in the form of a test question to measure HOTS based on Anderson’s taxonomy and Ichsan’s taxonomy. The second instrument employed is a questionnaire containing questions related to learning and various obstacles in e-learning. The research finds that the average HOTS score of elementary school students measured using Anderson’s taxonomy is 2.58; whereas, those measured with Ichsan’s taxonomy is 2.27 for all items. The HOTS measurement results using both taxonomies have some differences and one of them is in the C6 realm (create versus develop). The measurement results using the questionnaire suggest that WhatsApp is the frequently-used learning media (65.97%). Moreover, the most ideal learning duration according to the students is less than 3 hours (67.36%). The utilization of learning media become an important matter in the implementation of e-learning to enhance elementary school students’ HOTS. Serial books are an alternative solution so that students can understand environmental material well. The research concludes that differences in HOTS scores occurred between those measured with Anderson’s taxonomy and Ichsan’s taxonomy. Learning media to be further developed should be HOTS-based

Abstract

Non-thermal plasma is one of the new techniques that is being focused on in the medical world, one of which is used for sterilization because non-thermal plasma is known to have a bactericidal effect. Reactive species produced by non-thermal plasma are antimicrobial. One factor affecting plasma species' reactive composition is the gas source used. Therefore, this study aimed to determine the effect of reactive species produced from non-thermal plasma generation of SDBD using different gas sources, namely free air, oxygen, and nitrogen, in treating Escherichia Coli bacteria. The gas flow used is 1 liter/minute. Reactive species produced by plasma were characterized using Optical Emission Spectrometry (OES). SDBD Non-thermal plasma treatment for Escherichia Coli bacteria samples was repeated three times for each treatment, and then the Anova test was performed. The results of this study indicate that bacterial death at the decontamination level depends on the composition of the gas used during treatment. Plasma using an O2 gas source has a more effective inactivation ability, namely 6 x 107 CFU/ml, compared to the control, which is 409 x 107 CFU/ml. At the same time, the treatment results with free air and nitrogen gas sources were 6.33 x 107 CFU/ml and 41.67 x 107 CFU/ml. These results indicate that the composition of ROS and RNS influences bacterial inactivation, where ROS is more effective in inactivating bacteria than RNS

Abstract

Learning innovation in the midst of a situation like now needs to be done to adapt to the times. The times require teachers to continue to innovate by modernizing learning activities to suit the interests of students. The purpose of this research is to produce a learning innovation by combining inquiry learning and the use of information technology called Inquiry Learning Spaces (ILS) based on Go-Lab. The method used in this development research is 4D which has the stages of Define, Design, Develop, and Disseminate. This research will focus on the first three stages: Define, Design, Develop. At the Develop stage, validation is carried out on the product being developed. Validation was carried out by 3 experts in the fields of Physics Education, Media, and Learning Technology. Product reliability is also carried out using a percentage of agreement. From the results of expert validation, it was found that the product developed had an average score percentage of 88.31% with a very valid category. In addition, the percentage of agreement results show that each instrument's percentage has a value above 75% in the reliable category. Several criticisms and suggestions from the validator became a significant improvement to improve the Inquiry Learning Spaces (ILS) which was developed so that it could be used in science learning in junior high schools.

Abstract

The Bengkaung area, Batulayar District, West Lombok is suspected to be very vulnerable to the risk of earthquake hazards. However, in this area no scientific research, either geological or geophysical, has ever been carried out regarding this hazard. How are the physical characteristics of the lithology and structure in the area to the risk of earthquake disaster? The purpose of this study was to determine the physical characteristics of the lithology and subsurface structures that were validated by the level of damage. The method used is the geoelectric method and local building damage data. The results of the 2D geoelectric anomaly modeling show the characteristics of the subsurface lithological layers in the form of sand, sandstone, clay, andesite lava faults, fresh andesite lava, and granite. The fault was detected in the center of the study area in a north-south direction. Earthquake hazard analysis shows that the cause of the high risk of earthquake hazard in Bengkaung Village is the presence of faults and cohesive lithology. The highest potential risk is in the southern part of Bengkaung Village. The southern area of ​​Bengkaung Village is dominated by clay that has cohesive properties, especially on the surface. The western and northern parts of Bengkaung Village have medium and low vulnerability to earthquake hazards. The last two areas are dominated by non-cohesive soils in the form of sandy soils and lapilli pumice

Abstract

Kidney stones are a disease due to the buildup of substances that are not needed in the urinary system. Knowledge of the composition and type of stone is required in the treatment of action. Micro CT is one of the modalities that can be used in determining the composition of kidney stones. However, there are limitations when using single-energy micro-CT. Stone attenuation has almost the same value when using single energy, therefore it is necessary to use dual-energy CT to determine the difference in stone attenuation more precisely. The image of the dual-energy CT micro-energy stone needs to be processed before analyzing and determining the rock composition. Image fusion is one of the image processing techniques that can be used. The purpose of this study was to determine the effect of image fusion on the image quality of five kidney stones. The stages in the research carried out are collecting high energy and low energy projection image data, and performing image fusion on the two projected image data. The results obtained are first, the dual-energy CT image fusion affects the image quality which can be seen from the increase in the signal to noise ratio (SNR) value. A high SNR value provides the best image quality information

Abstract

This study aims to analyze the content of the magnetic mineral compound of natural iron sand on the beach of Lombok Island. This study uses the experimental method by taking primary data which is carried out in three locations, namely at Ijobalit Beach (East Lombok), Cemara Beach (West Lombok), and Telindung Beach (East Lombok). The study stage begins with a separation of natural iron sand, then a magnetic mineral separation is carried out to obtain Fe3O4 powder. The last stage is testing the Fe content using AAS (atomic absorption spectrophotometry). The research results were obtained by the percentage of magnetic mineral content from Ijobalit beach sand, Cemara Beach, and Telindung Beach respectively 93.56, 72.99, and 87.00%. The results showed that natural iron sand from Ijobalit beach had great potential to be used as a basic material for making microwave absorbers.
