Abstract

The implementation of HOTS in the learning process is considered capable of improving the quality of education in Indonesia. However, in online learning conditions, there are many obstacles and limitations to training HOTS in Biology lesson. This study aims to describe biology teachers' knowledge, preparation, and implementation of HOTS training during online learning. This study uses a qualitative approach to the type of phenomenology. This study involved 12 Biology teachers at SMA and SMK in West Java. The data collection technique is carried out through interviews via WhatsApp Call. The data analysis technique used is through reduction, data review, and conclusions drawing. Based on the results of data analysis, it was found that the teacher’s understanding of HOTS learning is still weak, and the implementation of HOTS training during online learning is still not optimal. The most widely used learning model is Problem based Learning. The constraint implementation of online HOTS training is inseparable from the online learning barriers, but teachers also continue to try to handle these barriers with various solutions.

Abstract

Micro-earthquake (MEQ) distribution describes subsurface conditions that can contribute to monitoring the dynamics of geothermal reservoirs. Thus, the distribution of MEQ hypocenter locations with high accuracy becomes extremely important. Experiments were conducted with 3 variations of geometry and number of seismic stations, while Geiger and Coupled Velocity-Hypocenter methods were used to determine the location of MEQ. Experimental results show that in determining the location of the MEQ, the geometry and number of seismic stations played an important role. Increasing the number of stations with relatively long distances can result in less accurate locations of MEQ, error and bias in determining the location of MEQ will be greater when the azimuth gap value is greater. This is shown by the distribution of MEQ that are more spread out in variations 4A and 4B (4 seismic stations) compared to the distribution of MEQ hypocenters using data from 8 seismic stations. The azimuth gap variations of stations 4A and 4B are 283° and 267°, and 8 stations have a value of 222°. The large value of the azimuth gap is due to the distribution of stations only on one side so that there are horizontal angles that are not covered by seismic stations.

Abstract

Intensive exploitation of geothermal injection and production can trigger microearthquakes which it signals come from dynamic fractures. The purpose of this study is to decide the impact of local magnitude on mitigation in geothermal fields based on soil acceleration and vulnerability of seismic in geothermal fields. This study uses seismic wave recording data and the geology of the research area. It is focable on calculating local magnitude, ground acceleration and seismic susceptibility index to earthquakes based on ground acceleration and seismic susceptibility index in geothermal fields. The maximum amplitude value represent that the medium classification class (3<A0<6) is associated with a moderate degree of deformation. Natural frequency value are found with a moderate classification (4<f0<10) around the area of injection wells and production wells, indicating that the research area has a moderate level of soil hardness structure. The peak ground acceleration in the study area is classified as moderate (0.25<PGA<0.7) which means that the area has a moderate level of risk. Vulnerability of seismic in the study area is included in the low classification (Kg<10). The local magnitude impact on soil acceleration and vulnerability of seismic in this study has a moderate risk and can be categorised as safe. In the future, this research serves as a basis for proper decision-making in geothermal energy operations, monitoring, and infrastructure development

Abstract

In Lombok, the traditional process of dyeing woven fabrics primarily involves the use of synthetic dyes, which can contribute to environmental pollution. This study aimed to identify the characteristics of woven yarn and assess the effect of dye solution pH on yarn properties when using teak leaves (Tectona grandis) to produce dye powder through a mechanical thermal method. The thread coloring process comprised mordanting, coloring, and fixation stages, with the assistance of Android applications for color analysis and a Universal Tensile Machine Type RTG-1310 to assess mechanical properties. The results revealed that dyeing yarn with anthocyanin powder from teak leaves yielded a range of colors, including shades of gray, brown, and red. The highest tensile strength observed was 2,664 cN/dtex, and the solution's pH significantly influenced the dominant color, with red being prominent. Notably, optimal tensile strength (1,649 cN/dtex) was achieved at pH six. These findings highlight the potential for producing high-quality cotton threads using different dyeing processes and techniques. The study's insights contribute to both environmental protection and thread quality enhancement in the textile industry

Abstract

The study aims to test the effectiveness of using the audio analysis software, Mictester, on smartphones in experiments on standing waves in order to improve students' understanding of concepts in high school. The sample consisted of 19 students of 11th grade at State High School 1 SoE. The instrument used was a test sheet of conceptual understanding of standing wave matter. The results show a significant improvement in students' understanding of concepts after the application of Mictester for audio analysis on Android devices/smartphones. Thus, standing wave experiments that utilize Mictesters software for audio analytics can be an alternative in physics learning, replacing conventional experimental equipment such as oscilloscopes, thereby reducing the cost of experiments.

Abstract

In the context of Physics learning, verbal representation is very important to foster problem solving skills. However, the role of these representations has not been thoroughly measured and supported by good measurement instruments. In addition, the topic of optical instruments has concepts that can be expressed with verbal representations and is one of the important topics in physics. Therefore, in this study, an instrument was developed to measure students' verbal representation ability on optical instrument topic. The objectives of this research are to (1) determine the instrument's construction and (2) find out the feasibility of the instrument. The instrument was developed following the modified Wilson, Oriondo, and Antonio procedure through three stages: design, testing, and test preparation. The test was piloted on 88 randomly selected students who had studied optical instrument topic. The analysis carried out in this development includes content validity, item-model fit, reliability, and item difficulty level analysis. The development was successful in providing feasible test instrument items for evaluating students' verbal representation of optical instrument topic. This instrument is expected to be used to capture information about students' verbal representation ability, which will then be analyzed to produce more appropriate physics learning instructions.

Abstract

The laboratory is one of the important facilities and supports the implementation of learning in tertiary institutions. However, in carrying out practicum activities, students are often constrained by information regarding names, functions, and steps for using instruments. Therefore, the need for information about laboratory equipment is quite important for students. This study aims to produce a website based on a QR code to provide information about the instrument to users and the steps to use it. This research uses research and development methods with the ADDIE model (Analysis, Design, Develop, Implementation, and Evaluation). The questionnaire is used to measure user responses regarding the QR code and its application. Based on the analysis of the problems found, the QR code was successfully created. This QR code was validated by media experts and instrument content experts and obtained valid results. Users show a positive response regarding the use of the QR code for introducing of Refraction Laboratory instruments. Thus, a website-based QR code can be used to provide optical instrument information to users. However, socialization about its use is very necessary for laboratory users.
