ABSTRACT
The Covid-19 pandemic impacted the increasing use of Android smartphones in teaching and learning. This study aims to build markerless VR-AR (Virtual Reality-Augmented Reality) as Android-based teaching materials for construction engineering students at Polytechnic. VR-AR-based teaching materials that have been established can reduce the risk of spreading Covid-19 without reducing learning quality. This research used the V-model method, which is divided into two parts, particularly development and testing activities. Testing is performed by developers and examiners using ISO 25010. The test results of VR-AR-based teaching materials that have been established show that the teaching materials were very feasible in terms of functional suitability, compatibility, and usability. All functions of the VR-AR application operate smoothly and work successfully on various Android operating systems with different screen resolutions. Moreover, users were satisfied with the developed VR-AR-based teaching materials. They felt comfortable, fun, and excited when using the AR application. © 2022. All Rights Reserved.
ABSTRACT
The growth rate of green tourism/ecotourism in the province of Yogyakarta, Indonesia decreased drastically because of the government's program in the community activity restriction program to reduce the COVID-19 pandemic. The purpose of this study was to analyze public perceptions of ecotourism conditions during the pandemic by implementing health protocols and maintaining environmental sustainability. The research employed descriptive and quantitative analysis. The research subject was 222 beach ecotourism tourists in the Special Region of Yogyakarta, Indonesia during the pandemic period for a period of seven months (February-August 2021). They were recruited through incidental random sampling method. The analytical tools in testing the research instrument were convergent validity test with mean loading factors and square roots average variable extract, discriminant validity test with average variable extract (AVE), and reliability test with Cronbah's alpha and composite reliability (CR), structural equation modeling analysis (SEM) with Warp partial least square (PLS) 7.0. The results showed that ecotourism concern, ecotourism practices, were not significant on tourist satisfaction. Green promotion had an effect on ecotourism tourist satisfaction, and health protocols strengthened tourist satisfaction on tourists' interest in returning to ecotourism. © 2022, Intelektual Pustaka Media Utama.

ABSTRACT
The declaration of the movement control order (MCO) in Malaysia has led to the closure of the education sector due to pandemic coronavirus disease 2019 (COVID-19). The teaching and learning (T&L) structure shifted from conventional classroom education to fully online distance learning (ODL). The unprecedented experience of 'home quarantine' has multifaced impacts on students' mental health. The study aimed to obtain the correlation of technical and vocational education and training (TVET) students' depression, anxiety, and stress (DAS) in fully implementing online distance learning. A survey study was used using a quantitative approach and respondent was evaluated by the depression anxiety stress scale-21 (DASS-21). Understudy's t-test and one-way analysis of variance (ANOVA) were utilized to investigate the relationship between these perspectives. Analysis from the DASS-21 inventory revealed that 30% had severe or extremely severe depression, 41% anxiety, and 20% stress among the vocational students. Anxiety showed a hugely significant difference among genders and the department compared to depression and stress. Therefore, the finding suggests that some intervention must ensure online distance learning is conveniently accessible and congenial with practical work for the vocational student syllabus. © 2022, Intelektual Pustaka Media Utama.

ABSTRACT
This research aims to test the effect of the kit Programmable Logic Controller (PLC) on the achievement of vocational school students' competencies in electrical motor control courses for form 3 students in Aceh, Indonesia. Constructivist theory and Bloom's Taxonomy are referenced in this study in relation to learning. While the ADDIE model is used in relation to product development. This study used a quasi-experimental design with pre-and post-tests. The population (N = 333) in this study was level 3 vocational students in Aceh, Indonesia. The number of samples was 98 people, consisting of the experimental group (n = 50) and the control group (n = 48) selected by cluster random technique. The instruments used in this study included pre-and post-test interview protocols. The values of the KR20 reliability coefficient of the question items on the knowledge aspect were 0.97 and 0.81 on the skills aspect. The results of the descriptive analysis found that the experimental group (mean = 64.08;SD = 4.548) showed better competency achievement than the control group (mean = 63.06;SD = 5.487). The result of hypothesis test using Mann Whitney test is [Asymp. Sig. (2-tailed) = .000, p <0.05] which means that the teaching aids developed have successfully had a positive effect in improving the achievement of student competencies. The implications of this study have produced a teaching aid that can be used as a template by teachers to build teaching aids that are more affordable, easy and safe to use so that they can be motivated to innovate in learning and become a new career opportunity. Given that the Covid-19 epidemic has affected face-to-face learning, the proposal for further research is the need to integrate logic control programming (PLC) learning aids into a technology-based learning trend. Researchers, on the other hand, suggest a broader scope of study whether teachers and students in a wider area and other fields of knowledge related to the utilization of PLC programming.
