Abstract

A person's critical thinking style will determine the extent of critical thinking skills. This study examines differences in the critical thinking styles of biology teacher candidates based on academic level. The method applied in this study is non-experimental with a comparative design. The instrument used was the Yanpiaw Creative-Critical Style Test, which was given to several prospective biology teacher students from semester 2, semester 4, semester 6, and semester 8 as respondents. The results showed that there was a significant difference between the average critical thinking style between students in semester 2 and semester 6 (sig. 0.011 < 0.05) and between semester 2 and semester 8 (sig. 0.029 < 0.05). Based on the findings, it can be concluded that academic level or level does not always affect a person's critical thinking style. However, it is also possible due to academic majors, behavior style, and ethnicity (culture). Therefore, an educator needs to provide learning methods and media that can support the development of students' critical thinking styles.

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

This research aimed to study the antioxidant activity of several cultivars of fresh yam tubers and its flour and to determine the effect of processing and storage on antioxidant activity of yam flour. The research used Complete Random Design (CRD). This study was conducted in three stages and repeated 3 times.  At first stage, antioxidant activities of three types of yam were investigated.  The type of yam tuber which has the highest antioxidant activity was used for second stage. At second stage, the experiment was carried out to determine the effect of processing methods on the antioxidant activity of yam flour. The treatment which produced yam flour with the highest antioxidant activity was further used in the last stage.  At last stage, the experiment was carried out to determine the effect of storage on antioxidant activity.  At this stage, 3 different storage times was used (0 weeks, 4 weeks and 8 weeks). The results showed that types of yam and processing treatment gave significant effect on antioxidant activity, IC50, L*, a* and b*, and total anthocyanin of yam tuber and flour.  However, processing method gave insignificant effect on value of L* of yam flour. Type of yam with the highest antioxidant activity was purple yam with antioxidant activity 96,35%, IC50 44,95 μg/ml, total anthocyanin content 351,82 mg/100g, L* 46, a* 54, and b* - 21. The processing method that produce flour with the highest antioxidant activity was steaming which produce yam flour with antioxidant activity of 83.59%, IC50 67.48 μg/ml, total anthocyanin content 136.94 mg/100g, L* 66, a* 26, and b* -15. There was a decrease in antioxidant activity, total anthocyanin content, L*, a* and b* of yam flour during storage of 4 and 8 weeks

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

This research was conducted using the literature review method with the aim of evaluating and integrating relevant previous research by training students' critical thinking skills through an inquiry model in order to minimize science misconceptions. The results of the literature review show that the inquiry model is one of the most effective learning models for training students' critical thinking skills and minimizing science misconceptions. The inquiry model emphasizes students' own discovery by inviting students to observe; ask; gather; and communicate their findings. Previous research also shows that training students' critical thinking skills can be done through various approaches and strategies, such as using open questions in group discussions; the use of diverse resources; and the use of technology. Besides that; Science misconceptions can be minimized by inviting students to actively participate in learning, such as providing constructive feedback and providing authentic direct experience. From the results of the literature review, we conclude that training students' critical thinking skills through inquiry models can be a solution to minimize the occurrence of science misconceptions. Therefore, implementing the inquiry model in science learning can increase students' understanding of science concepts and also improve their critical thinking skills.

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

This research aims to describe the ecological values of meiobenthos as a bioindicator of water quality at Losari Beach, Makassar. The sampling method used was the purposive sampling method. The determination of the research location was also based on previous research which described the coastal location of Losari Beach as being polluted by chemicals and dangerous metals. The research data were then analyzed statistically to calculate meiobenthos density, diversity index, and uniformity index. The research results showed that the abundance of meiobenthos found during the research was 66946 indv/m2, consisting of 12 phyla and 91 species/genus. The stations at the mouth of the Tallo River, Jeneberang River, and Tanjung Merdeka are research stations that have high abundance. The phylum oligochaeta, ostracoda, tunicata, and ciliophora are phyla with high abundance compared to other phyla. Based on the research results, it was concluded that this phylum has a high level of adaptation to the entry of various pollutants into water bodies. The diversity and uniformity index shows that the meiobenthos types in Losari are classified as having a high and even diversity index. The dominance index also shows that no single meiobenthos type is dominant, except for those in the reclamation project area. Temperature, current speed, depth, brightness, salinity, pH, DO, seawater nitrate, and seawater phosphate have a correlation or relationship with the abundance of meiobenthos on Losari Beach, Makassar.
