The presence of technology is inevitable is several fields, including in fashion design. This paper identifies technology-based virtual fitting rooms. All types of technology-based virtual rooms were identified; offline, online, web-based, mobile-based. It has been found that some of the most commonly used virtual rooms in fashion design involves such technologies as 2D fashion design, 3D fashion design, digital communication, e-commerce, internet-based, ICT-based, e-magazines, and e-books. It has also been inferred that virtual fitting rooms are starting to change conventional ones.

Curcumin is one of the pigments which is used as a spice in Asian cuisine, traditional cosmetic, and medicine. Therefore, process for getting curcumin has been widely studied. Here, the purpose of this study was to demonstrate the simple method for extracting curcumin from Indonesian local turmeric and investigate the infrared spectra and thermal decomposition properties. In the experimental procedure, the washed turmeric was dissolved into an ethanol solution, and then put into a rotary evaporator to enrich curcumin concentration. The result showed that the present method is effective to isolate curcumin compound from Indonesian local turmeric. Since the process is very simple, this method can be used for home industrial application. Further, understanding the thermal decomposition properties of curcumin give information, specifically relating to the selection of treatment when curcumin must face the thermal-related process.

This study aimed to design a batik learning medium for vocational high school students in based on multiplatform. The application made was expected to support heutagogy approach – based learning and to deal with the development of science and technology integrated in the curriculum of vocational high schools. The application developed, namely e-botik, was an integration of several previously-designed applications using Code ignitor (CI) framework. The database used was My-SQL. It is commonly known that Code igniter is an open source web application framework utilized to create dynamic PHP applications. In this study, e-botik consisted of three main components including interface, database, and application programming interface (API). Some of the applications combined were ARtikon_joyful (Android-based), Video Kasumedangan Batik (movie player), Nalungtik Batik (desktop-based), Digi_Learnik (web-based), Batik UPI (manual), Batik Cireundeu (manual), and Lembar Balik (manual). The combination proceeded web-based so that it was compatible with various operating systems. The application (e-botik) was designed and then tested. The test was performed through whitebox testing and blackbox testing. The results of the test showed that it ran well and was able to be used a batik learning media. It is expected that students can utilize e-botik in selecting topics of learning batik in accordance with their competences and needs. This condition enables e-botik to support learning batik through heutagogical approach. In addition, the application was also validated in terms of both system and usage aspects.

This study explored the teachers’ digital literacy in secondary school and deciphered the most suggested way of enhancing secondary teachers’ digital literacy, overview levels, and the trends factors in the last five years of research. The methodologies in this study employed the traditional systematic literature review (SLR), which compiled some previous studies to be examined. The initial studies were only selected from an article published in a reputable journal indexed by Scopus. Of the 118 articles reviewed, 46 were selected to be included in the analysis. Significant findings summarize the fact that most of the last five-year research about teachers in secondary schools was impacted by the rapid development of technology and the demand for 21st-century skills. To summarize, as it is at the intermediate level, most secondary school teachers are digitally literate. However, future research may evaluate digital literacy training programs for teachers to assess what improvements should be made to delivery as well as existing frameworks used to test teachers’ digital literacy.

Expert systems are artificial intelligence (AI) that attempt to create data, and find data to solve problems. In the process this system will help the student on the basis of expertise. It allows the user to use the computer system as well as use the computer in a specific context. The world's education use expert systems to help the learning process.
