Abstract

The aim of this research is to determine the comparative anatomy of the stem of Gyrinops versteegii (Thymelaeaceae) in Sumbawa Island. Stem samples of G. versteegii were used from collections of the Agarwood Center Laboratory, Faculty of Mathematics and Natural Science, University of Mataram that were taken from Sumbawa Island. This research used permanent slides with freehand section and maceration methods. Observation data consisted of cortex tissues, xylem, pith, and Ca-Oxalate crystals. The results showed that there were four provenances of G. versteegii on Sumbawa Island, namely provenance Pantai, Hajumee, Kayuk Pisak, and new provenance (Tartar provenance). Comparison of anatomy between the stems of G. versteegii provenance Pantai with other provenances had differences in periderm thickness, the pattern of tissue sclerenchyma, interxylary phloem thickness, cortical parenchyma diameter, number of rows of wood parenchyma tissue, tracheid diameter, pith cell diameter, Ca-oxalate shape. Provenance Hajumee with Tartar and Kayuk pisak differed in trachea length, trachea diameter, and the length of the tracheids, while between the provenances of Tartar and Kayuk pisak differed in the frequency of the trachea, the length of the fiber tracheids, the arrangement of the pith radius, and the location of the pith.

Abstract

Grynops verstegii is a non-timber forest product commodity that has a very high economic value. People know this tree as the agarwood tree. In Lombok, the Beringin provenance is one of the leading provenances, so it is very important to conserve its germplasm. This study aims to find alternatives for gaharu development through seed production using in vitro culture techniques. This research was carried out in July 2021 at the Tissue Culture Unit of the Immunobiology Laboratory, University of Mataram. In this experiment there were 8 media treatments with different concentrations of BAP (Ssitokini) and NAA (auxin). The results showed that callus growth occurred on MS 1, MS 3, MS 4, MS 6, and MS 7 media. However, the best growth was obtained in MS 1 treatment with a combination of 1.0 ppm BAP and 0.5 ppm NAA. While most of the samples experienced browning and contamination.

Abstract

The Porang plant is a native Indonesian plant that produces tubers and can live in shady places. In general, there are two types of porang planted by the community, namely A. muelleri and A. konjac. This study aims to identify phyllosphere fungi associated with porang plants and the presence of these phyllosphere fungi. By using the 10-1, 10-3 and 10-5 distribution method and the patch method. The results of the study successfully isolated 21 isolates of phyllosphere fungi identified into eleven genera: Aspergillus, Cunninghamella, Fusarium, Mortierella, Mucor, Myselia, Neurospora, Paecilomyces, Pythium, Rhizoctonia, and Verticillium, and phyllosphere fungi were found on the upper epidermis surface. The conclusion is that the presence of phyllosphere fungi is anatomically on the upper surface of the epidermis.

Abstract

The low environmental and digital literacy levels of Indonesian students, as well as the suboptimal integration of local potentials such as Lombok educational tourism into science learning, are the main backgrounds of this research. This study aims to explore the potential of integrating the Contextual Inquiry Learning model with Virtual Reality (VR)-assisted educational tourism in order to improve environmental and digital literacy in junior high school students. The method used is a systematic literature study with bibliometric analysis of 1,000 Google Scholar indexed documents for the period 2010-2025. Data collection techniques were carried out through the Dimensions.ai and Google Scholar databases using Publish or Perish software, with document selection following PRISMA guidelines. Data analysis techniques include bibliometric analysis assisted by VOSviewer to visualize trends, networks, and keyword density, as well as content analysis to identify key themes. The results show that publication trends on this topic fluctuate with a significant spike in 2021 (5,411 publications), dominated by publications in the form of book chapters (18,831 publications). The primary research sources come from the fields of education, psychology, and information technology. The keywords with the highest density include "students," "learning," "inquiry," and "education," while "metacognition" and "general models" have high relevance. Network visualization reveals six main clusters emphasizing technology integration, problem-based approaches, collaboration, and the development of critical thinking skills. The discussion confirms that the integration of educational tourism, STEAM approaches, and VR can create immersive and contextual learning experiences that strengthen conceptual understanding while building ecological awareness and digital competencies. The conclusion of this study is that the Contextual Inquiry Learning model integrated with VR-assisted educational tourism has a significant impact on improving students' environmental and digital literacy. Consequently, this study provides a foundation for the development of a more innovative, relevant, and locally-based science curriculum, and encourages the need for teacher training in integrating VR technology and contextual inquiry approaches into 21st-century learning.
