This study aims to determine the impact of the IoT and VR-based hybrid model science practicum on prospective science teacher students’ creative thinking skills. In addition, the study introduces how to implement IoT and VR-based hybrid models in science learning. The approach used in this research is quantitative, with an experimental method of one-group pretest-posttest design. The sample consists of 43 prospective science teachers at Universitas Negeri Yogyakarta who were determined by purposive sampling technique. The instruments used include creative thinking tests and observation sheets to implement hybrid model science practicum learning. The quality of the instrument was analyzed with Content Validity Ratio, Fleiss Kappa, Confirmatory Factor Analysis, and Rasch Model. Data analysis included descriptive statistics, paired sample t-tests, and effect size. The result showed that descriptive statistic is a general distribution, paired sample t-test p<0,001, and an effect size of 4.15. The finding showed that there was a significant positive effect on creative thinking skills. The implementation of this science practicum provides a meaningful academic experience for students. The practical implications of this research are that the IoT and VR-based hybrid model science practicum could be used by a prospective science teacher on other topics. Besides that, prospective science teachers' students’ creative thinking skills could be increased.

Dengan berkembangnya teknologi, kesadaran akan pentingnya alat musik tradisional menjadi berkurang. Demikian juga dengan alat musik tradisional Bangka yang mulai kehilangan popularitasnya. Kondisi saat ini, para remaja di Bangka kebanyakan tidak dapat memainkan alat musik tradisionalnya. Begitu juga dengan anak-anak yang belum mengetahui dan bahkan tidak mengenal alat musik tradisional daerah mereka. Jika kondisi ini dibiarkan, dikhawatirkan keberadaan alat musik tradisional Bangka akan hilang, begitu juga dengan sumber daya manusia yang dapat memainkannya. Untuk menghindari hal tersebut, dibuatlah aplikasi pengenalan alat musik tradisional Bangka menggunakan Augmented Reality (AR). AR dipilih karena dapat memberikan gambaran alat musik secara real time dalam bentuk 3D sesuai dengan pergerakan kamera smartphone yang dinamis. Empat objek 3D alat musik yakni dambus, rebab, rebanatamborin, dan gong yang dibuat menggunakan Autodesk Maya. AR yang dibangun menggunakan metode berbasis marker. Metode ini dipilih agar lebih mudah digunakan oleh pengguna yang mayoritasnya adalah anak-anak. Selain itu, kelebihan metode ini memiliki tingkat akurasi posisi yang sangat tinggi. Unity sebagai engine untuk penerapan AR 3D modelling pada sistem Android dan Vuforia SDK sebagai engine pembentuk marker augmented reality. Pengujian fungsional memiliki hasil 100% dengan sistem yang berjalan baik. Hasil pengujian kinerja deteksi objek AR berdasarkan intensitas cahaya diketahui bahwa smartphone yang memiliki dua kamera di bagian belakang dapat mendeteksi objek dengan intensitas cahaya 0 Lux pada malam hari dengan kondisi gelap, sedangkan yang hanya memiliki satu kamera tidak dapat mendeteksi objek. Pengujian warna marker mendapatkan hasil modifikasi warna marker pink, kuning, dan hitam yang masih memungkinkan untuk pendeteksian objek, walaupun objek yang tampil tidak stabil. Dari pengujian kertas marker diketahui bahwa jenis kertas tidak berpengaruh terhadap pendeteksian objek. Pengujian beta dilakukan dengan cara membagikan kuesioner terkait pengalaman pengguna dalam penggunaan sistem. Hasil survei diketahui pengguna merasa sangat setuju dengan nilai sebesar 80%, bahwa penggunaan sistem dapat membantu mereka dalam mengenal alat musik tradisional Bangka. With the incessant development of technology, awareness on the importance of traditional musical instruments has declined. Similarly, teenagers living in Bangka no longer play their traditional musical instruments, and children are not exposed to their cultural heritage. However, if this continues, it is feared that the existence of traditional Bangka musical instruments will soon go extinct. To avoid this, researchers have proposed an application to identify this media using Augmented Reality (AR). This technique was chosen due to its ability to provide visuals of musical instruments in real time using 3D models in accordance with the dynamic movement of smartphone cameras. This comprises of four 3D objects namely dambus, rebab, rebanatamborin, and gong, which were designed and developed using Autodesk Maya. AR is built using marker-based methods, which was chosen for easy use because majority of its users are children, and its high level of accuracy. Unity was utilized as an engine for its implementation in the Android system, and Vuforia SDK as augmented reality marker-builder engine. Functional testing showed 100% results which means that the system is running well. From the results of the AR object detection performance test based on light intensity it is known that a smartphone with two cameras in the backside has the ability to detect objects with a light intensity of 0 Lux in dark rooms, while the other smartphone with one camera failed to detect the objects. Color testing obtained a modification of marker colors comprising of pink, yellow, and black which are still able to detect objects, although not stable. The paper test marker has no effect on object detection. Beta testing questionnaires were used to obtain information related to user experience. From the survey results, it is known that users strongly agree (80%) that the use of the system helps them to recognize traditional Bangka musical instruments.

The use of paper as a media for product promotion is still widely used by companies in introducing their products. Promotional media used include brochures and flyers which are indeed printed to be distributed to potential customers. This way of promotion has an impact on the large number of paper-based promotional media which are then discarded after viewing. As it is known that paper comes from trees, currently, there are many environmental problems originating from illegal logging of forest trees and deforestation, which have an impact on ecosystems and the natural environment. During the current use of technology, the use of product introduction promotional media can use Augmented Reality (AR) technology. With AR, potential consumers can see 3D objects from products being marketed so that paper use can be reduced. In building AR, we use Game Engine Unity and Vuforia to be able to display 3-dimensional objects. This research is also based on Android as the base of the operating system. For the case study, we use four furniture products such as tables, chairs, and sofas as a subject of implementation. The purpose of this research is to reduce the use of paper as a medium for product promotion. The results of the research are in the form of media applications for promotion of Augmented Reality-based furniture products. Testing uses black box testing to test the performance of the AR along with testing various marker conditions, such as in low light and high light condition.
