Abstract

Since a large number of characters are now known for Freycinetia Gaudich. and Pandanus Parkinson species, it appears useful to consider their use in identifying plants from Java. Fieldwork carried out for this study has provided stronger foundation for understanding morphological variation within the species. This study was undertaken to have a better understanding on the morphology of the family in order to make a better species delimitation. Characters of habit, stem, leaves, auricles, bracts, peduncle and pedicel, inflorescence, staminate flowers (male), pistillate flowers (female), cephalia and berries were found useful in delimitation and identification of Javanese Freycinetia, while characters of habit, stem, prop root, marginal spine, leaves, bracts, inflorescentia, peduncle, staminate flowers (male), pistillate flowers (female), cephalia, drupes were found to be useful for distinguishing among species of Javanese Pandanus.

Abstract

The leaf epidermis and mesophyll of fifteen species of Pandanus from Java were investigated to assess the value of anatomical features in species identification and classification. Characters of diagnostic importance are epidermal cell shape, differentiation of the abaxial epidermis into costa and intercosta, adaxial anticlinal cell wall outline, occurrence of raphides in the mesophyll, distribution of cubical crystals, pallisade cell shape, papillae on epidermal cells, and the stomatal complex. Leaf epidermal anatomy was found to be useful in the identification at species level.

Abstract

Genetic Diversity of Pandanus from West Java based on ISSR Markers. The genetic diversity of 10 species of Pandanus from West Java was examined using inter simple sequence repeat (ISSR) technique. Samples were collected from different localities in West Java. Two primers (ISSR2 and ISSR7) were selected as reliable amplifying ISSR markers. The two primers amplified 19 band position, with amplification size ranged from 200 to 1500 bp. Genetic distance for samples ranged from 0.267 to 0.957. Genetic distance was high (0.957) between P. pseudolais and P. spinistigmaticus, and between P. kurzii and P. pseudolais, where as genetic distance was low (0.267) between P. scabrifolius and P. bidur.

Abstract

Research on ethnobotanical studies and inventories of medicinal plants in the Betawi tribal community in Kelurahan Ciracas, Kecamatan Ciracas, East Jakarta that has been carried out has the aim of obtaining information related to knowledge of medicinal plants, which include various types of medicinal plants, along with parts of medicinal plant organs used, and how to process them by the Betawi tribal community. The research method used is descriptive, with data collection techniques through observation, interviews, documentation, and identification. The data from the study were then analyzed descriptively and tabulated to show a description of the morphological characteristics of each type of medicinal plant found. The results showed that in Kelurahan Ciracas, there were 30 types of plants from 24 families that were used by the Betawi tribal community in the area as medicinal materials. Parts of medicinal plant organs utilized include roots, stems, leaves, tubers, and rhizomes. Meanwhile, the processing is carried out by boiling, pounding, mashing, and kneading. How to use it is done by drinking, pasting, smearing, and dripping on the body part that is sick or to be treated.

Abstract

The 21st century increases competitiveness by requiring students to have various skills. Technology and learning media are very important to support the learning process. However, without new innovations in the use of this learning media, students will not achieve learning goals and master the skills needed. The purpose of this study is to design and develop interactive learning media in the form of flipbooks to improve students understanding and digital literacy on the classification of living things, Plantae sub-material, Angiosperm sub-division, especially about the types of medicinal plants used by the Betawi Ciracas people. It also aims to provide new knowledge with interactive digital learning media, so that it can be used while learning. The results of this research are in the form of an interactive flipbook named "Intobamaskutaras" (Intervarisasi tanaman obat masyarakat suku Betawi Ciracas). The methodology of this research is research and development using the ADDIE model, among others; Analyze, design, develop, implement, and evaluate. Data collection techniques are in the form of observations, interviews and questionnaires. The subjects in this study involved 10 students as the initial trial subject, and 36 students as the subject of the use trial. Based on the results of the validation of material experts, 90.83%, and media experts, of 91.36%, are included in the very good or very valid category. In terms of usability, it obtained an assessment percentage of 97.75% from the results of the response of teachers and students to the practicality of flipbooks. This shows that the beneficial aspect of this flipbook is very practical.Keywords: ethnobotany, flipbook, medicinal plants, research and development.
