Abstract

In the midst of the COVID-19 pandemic which limits humans from interacting directly, the trade sector, in this case buying and selling in traditional markets, is hampered. Therefore, the researcher took the initiative to create an innovation, namely an Android-based E-Market Information System application that helps improve the community's economy during the COVID-19 pandemic, while providing an alternative to digital sales when entering the new normal period. In this study also tested the feasibility level of the software that has been made. This research method is Design and Build using the system development method with the Waterfall model. Software testing is done through black-box testing, McCall's Quality Factor as an indicator to determine the level of software feasibility with a measurement scale using a Likert Scale. Interviews and questionnaires are techniques used to collect data, while data analysis techniques use descriptive quantitative analysis. The mandatory output targeted for this research is developing an E-Market information system in Minahasa. In addition, the results of this study are to be published in an International Journal, namely the Journal of Mobile Computing and Multimedia Communications as an additional output

Abstract

The importance of green technology to be applied by vocational education (VE) has not yet been realized in optimal behavior. The strong assumption is that they do not find it instantly beneficial, even though the operational competencies and cultural drivers still need to be understood. This research aims to measure the significance of the influence of green technology competence (GTC), socio-cultural norms (SCN), and perceived long-term benefits (PB) on green technology use behavior (UB). In addition, the mediating role of PB is also tested in bridging the indirect influence of GTC and SCN on UB. The expost-facto study was conducted in VEs with Adiwiyata status with a total involvement of 647 participants who joined as teachers and students. Data collection used a closed questionnaire with four Likert scales that had been tested for validity and reliability. Structural Equation Modeling was used to analyze the data through path analysis and bootstrap methods. This study proved the importance of PB as a determinant of UB in VE teachers and students. It also provides essential insights into how GTC and SCN play an essential role in developing PB and determining UB. These results have important implications for VEs in improving their competencies and socio-cultural foundations to promote the sustainable use of green technologies. VE can synergize with various stakeholders and socio-cultural communities to support the strengthening of social capital and technical and financial assistance. In addition, the adaptive power of VE to analyze the need for green technology integration must also be pursued.

Abstract

The purpose of this research id to develop an interactive multimedia as instructional media with Adobe Animate application on computer introduction material. To determine the feasibility of the interactive multimedia requires expert judgment in terms of materials and media as well as students. This is a Research and Development (R&D) which adapted from the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation), but only carried out until the Implementation. Validation is carried out by material experts, media experts, teachers, and students. Data collection techniques in this development research use a questionnaire. Data obtained from the questionnaire was then analyzed descriptively qualitatively and quantitatively. Based on four assessments which are material expert, media expert, teachers and students’ assessment, the level of feasibility of developed interactive instructional media is valid and worthy of being used as a computer introduction instructional media for Elementary school students. Thus, the use of this media helps connect students with enjoyable learning experience. As a result, a positive consequence of utilizing this interactive instructional media is that teacher must keep their materials up to date.

Abstract

This study aims to estimate the revenue of tourist destinations in Tomohon City using the multiple linear regression algorithm. The problem addressed is how to determine revenue estimates from various tourist spots categorized into nature tourism and cultural experiences. The research method employed is quantitative, using a multiple linear regression approach. Data were collected through interviews with tourist destination owners regarding ticket prices and visitor numbers, and then analyzed using Microsoft Excel. The results show that the independent variables, consisting of ticket prices (X1) and the number of visitors (X2), significantly affect the dependent variable, which is monthly revenue (Y). The regression equation model obtained is Y = -5594 + 250X1 + 2.26X2. Using this model, the next month's revenue prediction for each tourist destination in Tomohon City can be determined, demonstrating that the multiple linear regression approach is effective for estimating tourism revenue.
