This study aimed to determine the effect of the use of learning with Z-generation video on skeletal system material towards critical thinking skills. Z-generation was a generation that was born in 1997 2019. This learning was learning process where students are asked to make a video learning material for the skeletal system with contemporary songs, modern song lyrics, and designed according to the style of the younger generation of Z-Generation. This design of research is a quasi-experiment that uses the pretest posttest control group design. The population on this research was all science class 11 in State Senior High School 1 Prambanan consisting of 4 classes. The study sample was taken two classes based on cluster random sampling technique. The class was consisted control class and experiment class. The instruments that used in this study were the observation sheet of learning implementation with Contextual Teaching and Learning approach with Z-generation video, and the test of assessing critical thinking skills. Data from the study were analyzed by ANOVA. The results showed that class scores used learning with Z-generation video was 75.18. While the value of critical thinking of students in the control class is 60.54. The results of these values indicated students' critical thinking skills that make the Z-generation video higher than the control class. Then it could be concluded that learning with Z-generation video has a positive effect on students' critical thinking skills.

In the hospitality sector, attrition of employees is a big global concern. The intentions of employee sales are the proxy for the current turnover of employees. The management of shifting working ties is one of the daunting challenges facing hospitality organizations. The hotel sector uses its human capital to gain its strategic edge in the consumer services market. Experts stress that the hospitality industry is a highly guest-based market that determines the enterprise's performance through meetings between staff and visitors. This analysis uses qualitative literature studies in the collection of the related data.

This study aims to get answers to the question whether there is a relationship between group counselling services with changes in social behavior of students in SMP Negeri 49 Jakarta. This study uses a quantitative research method by using a modified Likert model which is a scale used to measure the attitudes, opinions, perceptions of a person or group of people about social phenomena. Answers from respondents that are quantitative where answers are given a score using a Likert scale. The results of this study are a regression test of Ŷ = 26.584 + 0.684X meaning that if the provision of group counselling services is improved, then changes in social behavior will also increase or grow. The determination of the variance was 0.442 or 44.2% and the significance test was 0.000 <0.05 so that it was stated that Ho was rejected and Ha was accepted. This means that the relationship between group counselling services and changes in social behavior is very significant. Keywords : Group Counseling Services, Social Behavior Change, Students

ABTRACT A teacher is a profession which had the point to guide and direct student. Teacher’s condition is crucial for the teacher’s performance processes when running the responsibility. One of considerate conditions is teacher’s efficacy and psychological well-being. A teacher who have a good efficacy and psychological well-being will have an impact to teacher’s organization commitment. This research aims to understand the impact of the teacher’s efficacy and psychological well-being for the organization commitment. Research methods which used is the quantitative method with regression-correlation approach. Population of this research is all teachers at Pa van der Steur Primary School and used a simple random technique sampling. The research results show that there is an impact from the efficacy themselves and psychological well-being for organization commitment with correlation value efficacy himself against commitment organization of 0,854 and psychological well-being of commitment organization 0.839 The results of determination is 0,768 which means contribution of efficacy themselves and psychological well-being for organization commitment is 76.8 % and the rest of it got influenced by other factors which aren’t researched.

Numerous factors contribute to a company's worth, one of which is Tobin's QThe greater the Tobin's Q value, the more promising the growth prospects of the company. This is because the greater the market valuation of a company's properties is in relation to its market value, the further likely it is that investors will make further sacrifices to acquire the firm. This research would investigate the relationship between human capital, capital markets, and firm valuation. Intellectual capital was quantified using the Public model—Q Tobin's quantifies a significant discount. Meanwhile, three control variables exist, which are scale, leverage, and development. The population of this sample is manufacturing firms that are publicly traded on the Indonesian Stock Exchange (BEI) between 2017 and 2020. Purposive sampling was used to assemble the survey, which included 252 individuals (firm-years). Multiple regression analyses and descriptive statistics are used in this report. Eviews 8.0 is used to analyze the data. According to this report, the VAIC (value-added intellectual coefficient) and stock market value have little impact on firm value. Meanwhile, the three control variables used have little impact on the intensity of the values.

Tangkin is an indigenous woven bag produced by Dayak tribe in West Kalimantan, which usually used to carry heavy luggage from forest garden to take home and vice versa. This paper aims to predict the elasticity modulus of Tangkin and identify factors which influenced it. Modulus elasticity reduced from Hooke’s Law experiment, by using tensile test method, pulled by external force from 5.0 – 40 N. There is three Tangkin’s miniature assessed. They are made from bamboo, brace-less configuration, and have typical pattern of woven for each other. The pattern of woven has alliance with finite geometric series mathematics method by using Math Lab. The stress-strain graph presented the elasticity characterisation of Tangkin is still in Hooke’s Law area. Tangkin’s elastic modulus tends to increase in longer height of cylinder-like, but decrease on larger surface area. It means the toughness Tangkin will obtained with skinny but long shape. The elastic modulus value of Tangkin 1, Tangkin 2, and Tangkin 3 equal to 5909.1 Pa, 5267.4 Pa and 4550.8 Pa respectively. The weave pattern also influenced the elastic modulus, due to the force distribute direction. The pattern that have tendency to direct the force distribution oppositely from gravitational direction, will increase the strength of Tangkin. Meanwhile the slope of direction of force distribution will twisted the tangkin. This research can be useful for stage manage the alternative elasticity practical based on indigenous physics.

Imaging using CT Scan utilizes the nature of the material that can absorb X-rays so the intensity of X-rays that penetrate the material will be attenuated. The attenuation coefficient of the material will provide information on the physical properties of it, in the image produced by CT Scan, the attenuation coefficients of the material is related to the number of Hounsfield Unit (HU). Alginate impression material is an irreversible hydrocolloid molding material that will form a gel when reacted with water without heating treatment process. The nature of alginate gel is elastic and has a fast setting time, often used in the manufacture of dentures. Alginate scanning using CT scan can provide information on alginate gel equivalents with human body tissue by comparing the HU values obtained. Alginate impression material that has been set up by using water is formed with a size of 11 x 11 cm with a thickness varying 5 mm, 7 mm and 9 mm and then scanned using CT Scan obtained an average HU of -51, which is equivalent to soft tissue such as lipid or breast.
使用CT扫描成像利用了材料可以吸收x射线的特性，因此穿透材料的x射线强度将被衰减。材料的衰减系数将提供其物理性质的信息，在CT扫描产生的图像中，材料的衰减系数与霍斯菲尔德单位(Hounsfield Unit, HU)的数量有关。海藻酸盐压模材料是一种不可逆的水胶体成型材料，不经加热处理，与水反应后会形成凝胶。海藻酸盐凝胶具有弹性和快速凝固的特性，常用于制造假牙。利用CT扫描对藻酸盐进行扫描，可以通过比较所获得的HU值，提供藻酸盐凝胶与人体组织的当量信息。将用水建立好的藻酸盐印模材料，形成尺寸为11 × 11 cm，厚度为5mm、7mm、9mm的尺寸，然后使用CT扫描进行扫描，得到平均HU为-51，相当于脂质或乳房等软组织。
