<![CDATA[Currently, the program contained in the training periodization focuses on physical training programs, techniques, and tactics for playing volleyball. However, the psychological condition is to blame if an athlete's performance fails. The generational difference between coaches and athletes greatly disrupts interactions, so a unique approach is needed that touches the psychological side of athletes in providing training and improving performance. This research aims to describe the level of understanding of coaches at the Buleleng Volleyball Academy (ABVB) regarding the psychology program of training periodization. This research is a descriptive analysis research, with 12 ABVB trainers as research subjects. Data were collected through observation and survey techniques with research instruments using two questionnaires. The first questionnaire determines the role of psychology in sports, and the second examines the coach's ability to implement psychology in training programs. Data analysis with data triangulation. This research was carried out during the Covid-19 pandemic, so it was carried out via Google Forms. The research results show that coaches understand the role of sports psychology but need to learn the form of training given to athletes. The conclusion is that ABVB coaches own sport psychology knowledge but have yet to apply it in handling athletes, so strengthening is needed to make coaches better at using it in training.]]>

<![CDATA[The sun's heat factor is the leading cause of discomfort when doing outdoor activities, which does not happen at night. However, it is also necessary to ensure that humans feel comfortable at night, even without sunlight. This study aims to develop a regression equation to predict the comfort scale of humans doing outdoor activities at night in humid tropical climates. This study applied a field research method involving 80 adult respondents consisting of 40 men and 40 women in an outdoor location in a humid tropical climate. The data collection method uses a questionnaire. Respondents as subjects were asked about their comfort level when they received local climate penetration that touched their bodies. At the same time, climate variables around the issue were measured. The climate measured consists of air temperature, radiation temperature, relative humidity, and air speed. The data analysis technique is quantitative descriptive. The research results found 2 regression equations, namely for the case of people sitting and walking casually. The regression equation was then validated by comparing it with other equations, namely PMV and PET. The regression equation from this study helps make decisions about facilities and outdoor space design that provide a sense of comfort for humans during the funeral.]]>

<![CDATA[Science learning activities in elementary schools (SD) still need to run effectively. Teachers' choice of an inappropriate learning model in teaching students causes students to need help understanding the material being taught well. This research investigates and analyses the strong influence of the problem-based learning model based on Balinese local wisdom on the significant reduction in science misconceptions in Class V elementary school students. This research is quasi-experimental, with a non-equivalent post-test-only control group design. The population is 203 students from 8 elementary schools (SD). The sample in this study was 32 experimental class students and 30 control class students who had previously been determined using random sampling techniques. Data on students' science misconceptions was obtained using the objective test method followed by the CRI (Certainty of Response Index) method and analysed using the two-way ANOVA test. The average science misconception of experimental class students was 7.78 in the low category, and the control class was 10.73 in the low sort. Inferential statistical analysis showed that the significance value was 0.000, less than 0.05 (0.000, less than 0.05). The research concludes a significant difference in science misconceptions between students who follow the problem-based learning model based on local Balinese wisdom and those who follow the conventional model in fifth-grade elementary school students.]]>

<![CDATA[The development of counselor performance assessment instruments, especially for group guidance services, is still being developed independently by each higher education institution. It tends to be non-standard and not entirely in line with the need to create counselor competency in implementing school group guidance services. This research aims to create a performance test instrument for group guidance services for school counselors that is valid and reliable by adapting the development model from Borg & Gall at three stages of development. By involving 5 subjects as testers for the acceptability of performance instruments, namely 2 lecturers and 3 school counselors. Thirty-nine construct validity and reliability testing subjects consist of 2 lecturers, 12 school counselors, and 20 practical students. This development resulted in a set of counselor performance assessment instruments in group guidance services consisting of 13 statement instrument items on the planning aspect and 27 on the practice aspect, tested as valid and reliable based on SPSS 26 analysis. Furthermore, experts and users have also validated the assessment instrument by meeting acceptability criteria (applicable, feasible, and appropriate). Thus, it can be concluded that the counselor performance test instrument product in group guidance has met the development objectives and can be used for assessment in the planning and practice of group guidance services in schools or clinical counseling supervision activities.]]>

<![CDATA[The competency of vocational high school students is still said to be lacking in work readiness. This is caused by a lack of encouragement for oneself, family, school facilities, school environment, etc. This research aims to analyze the mediating role of work motivation in determining vocational school students' work readiness. This research uses an ex-post facto quantitative approach with the path analysis method. Research subjects in 3 vocational schools in machining engineering expertise in class XII with a total sample of 193 people. Data collection uses questionnaires, interviews, and documentation. Hypothesis testing in this study used SmartPLS 3 software. The findings show that work competency and industrial work practice experience can influence work motivation. Work motivation can directly influence students' work readiness. Indirectly, work competency affects work motivation through work readiness. Indirectly, industrial work practice experience affects work motivation through work readiness. It was concluded that work motivation plays a role in determining vocational school students' work readiness, especially in class XII machining engineering, followed by work competency and industrial work practice experience. So it is recommended to the vocational school community always to be motivated so that students are ready to work, have sufficient competence and experience, and always pay attention to the 3 things researchers discovered and discussed because vocational schools aim to work, continue, and become self-employed.]]>

<![CDATA[Many factors influence scientific literacy, including students' lack of activeness and interest in reading in the learning process. Based on the observations, it was found that students' collaboration abilities still needed to be higher, with a percentage of 60% not understanding collaboration. This is because students are less active in communicating and interacting, and the learning model applied by teachers needs to be more creative and innovative. This research examines the effect of the Group Investigation (GI) type cooperative learning model on the collaboration abilities and scientific literacy of fifth-grade elementary school students. The type of research carried out was experimental research, with a nonequivalent pre-test and post-test control group design. The population of this study was 133 students. The sample in this study involved 19 students in the experimental class and 18 students in the control class. Collaboration ability data was collected using questionnaire instruments and test instruments in the form of objective questions for scientific literacy. Next, the data was analyzed using descriptive and inferential statistical techniques (t-test and Manova). Based on the t-test analysis, it was found that simultaneously, the GI-type cooperative learning model influenced students' collaboration abilities and scientific literacy. Based on descriptive analysis, the average score of the experimental group was more significant than the average score of the control group. The GI type cooperative learning model influences collaboration skills and scientific literacy.]]>
