Morpho-anatomical characterizationand DNA barcoding of Achillea millefolium L. Biodiversitas 23: 1958-1969. One of the important things to study the distribution of secondary metabolites in the plant body is to carry out the identification process. Morphological markers have several limitations to recognize plants, therefore supporting data is needed so that the information becomes more comprehensive. This study aims to identify Achillea millefolium L. based on morphological, anatomical, and DNA barcoding markers to obtain specific data and avoid confusion. Morphological studies were carried out descriptively using vegetative organs, while anatomical studies of rhizomes, stems, and leaves used the paraffin method. The DNA barcoding was performed by analyzinggenes from 3 different individuals. The research was carried out by amplifying and sequencing the partial gene in the ribulose-bisphosphate carboxylaselarge subunit (rbcL) regions and maturase-K (matK). The results showed that the plant had taproots, short stems due to root rosette and the leaves were double compound. The rhizome and stem tissues had almost the same structure, while the leaves had a tissue arrangement that was similar to other plants in general, except that the mesophyll tissue was undifferentiated. The results of DNA barcoding showed a percentage of identity above 98% for both the rbcLand matK genes.

Tempuyung or show thistle (Sonchus arvensis L.) belongs to the Asteraceae. Morpho-anatomy and DNA (Deoxyribonucleic Acid) barcoding of the plant correlates with species identification and metabolite synthesis. This research aims to look at morpho-anatomical structures and analyze the DNA barcode of Sonchus arvensis L (tempuyung). Three samples used for morpho-anatomical analysis are leaves, stems, roots, fruit, and seeds. Anatomical samples are made using the embedding method. DNA barcode uses multiple locus from plastid genome: rbcL and matK. Morpho-anatomical structure of tempuyung showed a similar structure of Sonchus genus. The stem presents in the intercellular space, whereas the roots and leaves present in the vascular tissue and the seeds. Fruits present in each part of the body. Tissues that formed root are epidermis, cortex, endoderm, and stele. Tissues that formed stem are epidermis, cortex, and stele. Tissues that formed leaf are epidermis, cortex, phloem, and xylem. Tissues that formed the fruit and seed are paranormal and sclerenchyma tissues. Sonchus arvensis sequence for rbcL has a similar 100% maximum identity to rbcL gene of S. arvensis, Sonchus asper, and Sonchus oleraceus, whereas Sonchus arvensis matK sequence has a similar 99.31% maximum identity to other S. arvensis matK sequences in BLAST system. These findings provide morpho-anatomical features and DNA barcoding for identification of S. arvensis. from others species in the same genus. Thus also can be considered as pharmaceutical standard.

Sukamade River is one of the main rivers in Meru Betiri National Park, especially at Sarongan Resort. Macrofauna benthic community in this river are in the protected areas that allegedly still original, and has not got the impact of human activity. Information about the diversity of gastropods class in Sukamade River in limited encourage to do research on the diversity of gastropods in this place. This research was conducted to determine the diversity of gastropods in Sukamade River. Gastropods samples taken at fi ve stations those are in estuary, middle, and part of the river that closer to upstream river using surber-net and hand net. Surber-net used to take samples in watersheds zones and riparian zones using hand net. Samples were obtained, inserted the container that contains the fi xative solution that formed by formalin 6% for preservation. Samples that have been preserved, and then sorted, identifi ed and counted the number of individuals of each species, and data analysis. Data analysis, among others, to calculate the diversity index, evenness index, and dominance index in the
