This research was conducted to analyze the effectiveness of Hybrid Guided Inquiry on HOTS and students' communication skills in Circular Motion material. The method used in this research is quantitative research with a quasi-experimental. 10th-grade students of MIPA in SMA Negeri 1 Malang were used as the observed population; the samples taken were students 10 MIPA 2 and 10 MIPA 4. The MANOVA test is a technique used to test hypotheses and then analyze the effectiveness of H-GI in optimizing HOTS and students' communication skills. Analysis of the results of this study found that the HOTS score for the experimental class was 78.4 while for the control class was 71.1. Meanwhile, the communication skills results between the experimental class and the control class were 78 for the experimental class and 72 for the control class. Thus, H-GI is effective in optimizing HOTS and communication skills of students compared to direct learning, which uses PBL. The research results could be the basis for making learning more effective in physics material, especially the Circular Motion concepts.
本研究旨在分析混合式引导式探究在HOTS教学中的有效性，以及学生在圆周运动材料中的沟通技巧。本研究采用准实验的定量研究方法。以Negeri 1 Malang SMA MIPA的10年级学生为观察人群;所取样本为10 mipa2和10 mipa4学生。MANOVA检验是一种检验假设，然后分析H-GI在优化HOTS和学生沟通技巧方面的有效性的技术。本研究结果分析发现，实验班的HOTS得分为78.4分，而对照组的HOTS得分为71.1分。与此同时，实验班与控制班的沟通技巧得分分别为78分和72分。因此，与使用PBL的直接学习相比，H-GI在优化学生的HOTS和沟通技巧方面更有效。研究结果可作为提高物理材料特别是圆周运动概念学习效率的基础。

In this pandemic era, learning style transformation required students to change their learning style to self-directed learning. However, a lack of student initiation led to sub-optimality of education, particularly for some materials such as momentum and impulse, which are classified as complex concepts in physics. This study aimed to examine the impact of iSpring learning media in conjunction with the Know-Want-Learn (KWL) learning model on students' self-directed learning. The data analysis used in this study was an independent t-test to analyze the difference in self-directed learning between students in the control and experiment groups. Furthermore, this study was intended to investigate students' self-directed learning during the implementation of iSpring learning media integrated with the KWL learning model. This study included 31 students divided into the control group and the experiment group, which was chosen using purposive sampling. The difference in students' learning independence between the control and experiment groups was examined using a post-test-only research design. Students in the experimental group demonstrated greater learning independence than students in the control group, which did not use the iSpring integrated with the KWL learning model. This result also implies that after implementing iSpring as the learning media integrated with KWL as the learning model, students' self-directed learning differed in the experiment and control groups.

Studies investigating the walking patterns of elderly men are well documented, however, there has been no investigation of the gait parameters that specifically reflect the walking motion of elderly men. This study aimed to identify reliable gait parameters to represent the walking motion of elderly Japanese men. 33 elderly men (65 to 74.9 years old) and 20 very elderly men (≥ 75 years old) participated. A 3-dimensional motion analysis system was used to collect kinematic data and 52 gait parameters were analyzed namely; spatiotemporal gait, joint angle, and angular velocity parameters (peak value and peak timing at the hip, knee, and ankle joints. Our results showed that walking speed, cadence, walk ratio, gait cycle, peak joint angle timing, and angular velocity parameters significantly differ between elderly men and very elderly men. Delayed peak timing in the joint angle occurred during the terminal stance phase and pre-swing phase. The accurate parameters for walking motion in old Japanese men as they age may result from the peak timing of joint angle parameters and the peak value of angular velocity parameters.

This study aimed to identify reliable gait parameters to represent the walking motion of elderly Japanese men. 33 elderly men (65 to 74.9 years old) and 20 very elderly men (≥ 75 years old) participated. A 3-dimensional motion analysis system was used to collect kinematic data and 52 gait parameters were analyzed namely; spatiotemporal gait, joint angle, and angular velocity parameters (peak value and peak timing at the hip, knee, and ankle joints. Our results showed that walking speed, cadence, walk ratio, gait cycle, peak joint angle timing, and angular velocity parameters significantly differ between elderly men and very elderly men. Delayed peak timing in the joint angle occurred during the terminal stance phase and pre-swing phase. The accurate parameters for walking motion in old Japanese men as they age may result from the peak timing of joint angle parameters and the peak value of angular velocity parameters.","PeriodicalId":31460,"journal":{"name":"Jurnal Ilmiah Pendidikan Fisika AlBiruni","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43817800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Osteoporosis is a common metabolic disease that is frequently overlooked. This disease primarily affects adult women and causes bone thinness and fragility, which leads to fractures. DXA (Dual Energy X-ray Absorptiometry) is used to diagnose osteoporosis by measuring bone mineral density. These devices are expensive and not widely available for treatment. This study aimed to find a correlation between the texture value of an image of the patellar bone and the density of the lumbar spine, which can then be used to detect osteoporosis. This study's sample size was 19 subjects, and their bone mineral density (BMD) was measured using DXA. An X-ray was then taken to obtain an image of the genu bone. The stages of the research are as follows: 1) preparing the X-ray image of the bone; 2) determining the image texture value method of gray level co-occurrence matrix 3) investigating the relationship between texture values and BMD in the lumbar spine. The correlation test results revealed a statistically significant correlation between the texture value and the BMD of the lumbar spine for the correlation and variance characteristics (P less than 0.05). As a result, the value of the texture of the image of the patella bone can be used to detect osteoporosis.

Based on the amount of discharge or current, the river flows in Central Kalimantan have the potential to produce electrical energy. The purposes of this study were to design an undershot type of floating waterwheel and to test the effective bending angle at the radius of the grasshopper elbow in producing the most optimum power. This research uses experimental methods. The tools used are: mobile phone, multimeter, the gate of light, timer counter, flow rate, and the dimensions of the waterwheel diameter is 6 meters. Grasshopper angles vary from 0°, 30°, 45°, 60o, and 90° with a submerged blade depth of 0.24 m. The results showed that the undershot waterwheel with a flexible pinwheel (like a grasshopper's elbow) produced a faster and more effective rotation than a wheel with a fixed pinwheel and blades. Because the waterwheel has a flexible pinwheel and the butterfly blades experience little resistance when moving in water, the wheel generates more electrical energy than a wheel with fixed pinwheels and blades.At the angle of bending of the radius of the grasshopper blade 30º with the butterfly blade, it produces more optimal electrical energy than angles 0°, 45°, 60o, and 90°. Suggestions for further research are to test the waterwheel in weak and medium current rivers
