This work comprised of the comparative study of arsenic (As) uptake efficiency by Pteris vittata and Pityrogramma calomelanos grown in (i) As amended soils (0–600 ppm) and (ii) As tainted water (40 ppb) using a new compact continuous flow phytofiltration system in a tropical greenhouse. The As hyperaccumulation efficiency was dependent on the growth medium for the two fern species. The highest level of As detected in the fronds of P. vittata was 19,300 ± 190 ppm (dry weight basis) and 11,600 ± 230 ppm for Pityrogramma calomelanos, after growing for 78 days in soils amended with As. In the compact continuous flow As phytofiltration system experiments, Pityrogramma calomelanos was found to perform better than P. vittata in phytofiltrating As contaminated water under waterlogged conditions. During the 167 h of phytofiltration experiment, the removal efficiency was approximately 99% and 67% for Pityrogramma calomelanos and P. vittata systems respectively, based on an initial 40 ppb As. Pityrogramma calomelanos also required a shorter acclimatization time than P. vittata under waterlogged conditions.

Comparative study of Ciung Wanara traffic island in Gianyar with Satrya Gatotkaca traffic island In Tuban. Traffic island is an island in the middle of the road that serves to direct the flow of traffic and a waiting place for the user to cross the road. Traffic island of Ciung Wanara in Gianyar and Traffic island of Satrya Gatotkaca in Tuban had turned their function of being a place of recreation for the community. The purpose of this study is to invent existing condition of Ciung Wanara and Satrya Gatotkaca traffic island. This study also provides recommendations in the form of designs that can improve the function of the site. The method used in this research was field survey by conducting observation, distributing questioner and doing interview. Research showed that, users in Ciung Wanara traffic island were dominated by student while users who came to the traffic island Satrya Gatotkaca were dominated by employees. The selection of vegetation bettwen the traffic island of Ciung Wanara and traffic island of Satrya Gatotkaca very different. Vegetation in the traffic island of Ciung Wanara used more of large size vegetation that can block the view of the user of the vehicle, while the vegetation used in the traffic island of Satrya Gatotkaca use lower plants size. The recommendation given in both locations was to add access to traffic island of Ciung Wanara so as to make easier for users to find the right place to cross, while traffic island of Satrya Gatotkaca was arraged it crossing space for more convenient and secure for users to passed the crosswalk.

This study was undertaken to identify methods of mass multiplication for five ornamental, economically important ferns (Nephrolepis biserrata (Sw.) Schott., N. cordifolia cv. ‘‘duffii’’ (L.) Presl., N. exaltata cv. bostoniensis (L.) Schott., Pteris vittata L., and Cyclosorus dentatus Link.,) and three threatened ferns, namely, Cyathea spinulosa Wall. ex. Hook, Pityrogramma calomelanos (L.) Link., and Microsorum punctatum (L.) Schott., through in vitro techniques. Collections were made from different biodiversity zones of India including Northeast Himalayas, Kumaon Himalayas, and Western Ghat and successfully introduced and grown in a fern-house. Aseptic cultures were raised at the morphogenic level of callus, axillary shoot, multiple shoot, and rooted plants. An optimized medium is described for each fern species. Plantlets were also produced from spore culture of Cyathea spinulosa and successfully hardened under fern house conditions.

The effect of various concentrations of Lead on stipe and leaflet anatomy of Pteris vittata and Pityrogramma calomelanos were investigated. Fernlets were transplanted into 5 kg pots of soil pre-treated with five different concentrations of Lead, adequately watered and arranged in a complete randomized design in the screen house. Pots with no Lead treatment served as control. At twelve weeks after planting, plants were carefully removed, washed and taken to the laboratory. Anatomical sections of leaflets and stipe of each of the treatments were carried out with a sledge microtome (10-15 μm). Microscopic observations of structures were made after staining the sections. In Pteris vittata, the thickness of the cuticle of the stipe increased with increasing Lead concentrations but the reverse of this was observed in Pityrogamma calomelanos. There was also significant reduction of epidermal and mesophyll cell area of both species with increasing Lead concentrations. It can be concluded from this study that P. vittata has a higher tolerance level to Lead than Pityrogramma calomelanos. Key words: Anatomy, Cuticle thickness, Ferns, Lead, Pteridaceae.

The tourist area of Cunca Rami Waterfall has natural beauty and environmental conditions allow ferns (pteridophyta) to grow and develop diversity high level. This study aims to inventory the types ferns potential in the Cunca Rami West Manggarai waterfall zone East Nusa Tenggara Province, so that is expected to become important information material for the community and local government in developing natural potential-based tourism owned by West Manggarai Regency. Inventory of ferns was carried out through an exploratory method with random sampling which were subsequently identified by reference to the flora book Steenis, et al (2008). The results showed that there were 15 fern types, namely Adiantum diapahnum L.; Drynaria sparsisora (Desv.) More; Pityrogramma calomelanos Link.; Plagigyra sp.; Asplenium belangeri Bory; Asplenium caudatum forst.; Davalia sp.; Diplazium esculentum Swarz.; Dryopteris ferox; Dryopteris pteroides; Lindsaea decomposita Willd; Nephrolepis exaltata schott.; Nephrolepis sp.; Pteris biaurita L.; Pteris vittata L. Then classified into 8 family types, namely Polypodiaceae, Aspleniaceae, Davalliaceae, Athyriaceae, Dryopteridaceae, Lindsacaceae, Neprolepidaceae, and Pteridaceae. Fern species in the Cunca Rami Waterfall area has great potential, but the surrounding community has not utilized use potential full.

Arsenic (As) is an ubiquitous trace metalloid found in all environmental media. Its presence at elevated concentrations in soils derives from both anthropogenic and natural inputs. Arsenic is a toxic and carcinogenic element, which has caused severe environmental and health problem worldwide. Technologies currently available for the remediation of arsenic-contaminated sites are expensive, environmentally disruptive, and potentially hazardous to workers. Phytoextraction, a strategy of phytoremediation, uses plants to clean up contaminated soils and has been successfully applied to arsenic contaminated soils. It has the advantage of being cost-effective and environmentally friendly. A major step towards the development of phytoextraction of arsenic-impacted soils is the discovery of the arsenic hyper accumulation in ferns, first in Pteris vittata, which presented an extraordinary capacity to accumulate 2.3% arsenic in its biomass. Another fern, Pityrogramma calomelanos was found to exhibit the same hyperaccumulating characteristics. After that, screening experiments have revealed that the Pteris genus is really unique in that many species have the potential to be used in phytoextraction of arsenic. In general, these plants seem to have both constitutive and adaptive mechanisms for accumulating or tolerating high arsenic concentration. In the past few years, much work has been done to understand and improve the hyperaccumulating capability of these amazing plants. In particular, the field of molecular biology seems to hold the key for the future of the phytoremediation.
