Abstract

Lichen is a symbiotic organism between fungi and algae which is used as a bioindicator of air pollution. This study aims to determine the diversity of species and distribution areas of lichen in Baturraden Botanical Garden, Banyumas Regency by using purposive random sampling method. Sampling was carried out at three stations, namely flora of Java forest (Javanese mountain plants), resin tree forest (damar forest), and natural forest. Based on the results of the research at the three observation stations, 10 species of lichen were found. The lichens found belonged to 8 families including Cryptothecia striata (Family Arthoniaceae), Dirinaria picta (Family Caliciaceae), Graphis scripta and Diorygma poitaei (Family Graphidaceae), Parmotrema austrosinense and Parmotrema perlatum (Family Parmeliaceae), Psilolechia lucida (Family Psilolechiaceae), Lepraria caeosioalba (Family Stereocaulaceae), Normandina pulchella (Family Verrucariaceae), Opegrapha atra (Family Opegraphaceae). The thallus types of lichen found were foliose, crustose, and squamulose species. The average value of the species diversity index from the three stations is H' = 1.493 in the moderate abundance category. The distribution of lichens in Baturraden Botanical Garden is influenced by climatic factors (light intensity, air temperature, humidity), topographic factors (altitude) and environmental conditions.

Abstract

Sleman Regency has the most temple cultural heritage in Yogyakarta, supported by Green Open Space (GOS). The area is a habitat for urban birds and can be used as an indicator of environmental quality. This study aims to analyze the environmental quality based on the soundscape and character of the bird community in the GOS of Prambanan Temple and Ratu Boko Temple. Sound recordings were taken with a smartphone, and the recording time was set using the Arbimon touch in the morning, afternoon, and evening. The sound recordings are used to calculate acoustic indexes. The sound recordings and spectrograms are processed to identify bird species and calculate the Bird Community Index. The number of bird species was higher in the Ratu Boko area. According to the NDSI value, the sound of biophony at Ratu Boko Temple is more dominant than anthrophony and geophony. The environmental quality in the Prambanan Temple area is in the low category than in the Ratu Boko Temple area, which is classified as a medium category. The area's topography, the arrangement of vegetation, and the noise of vehicles due to the proximity to the highway affect the environment quality in temple areas.

Abstract

Productivity and quality of crops can be increased through polyploidy plants induced by antimitotic compounds such as vinka alkaloids.The use of vinka alkaloids has never been applied to Sword bean (Canavalia ensiformis), a tropical legume belonging to the Fabaceae family. This study aimed to determine the effects of vinka alkaloids treatment on the morphological characters of Sword bean. The treatment consist of four different vinka alkaloids concentrations (0.5%, 1.00%, 1.50%, 2.0%, and untreated (0.0%) act as control. The plants were arranged in a completely randomized design. Treated plants were characterized based on morphological traits such as plant height, leaf area and dry seed weight. The results obtained revealed significant difference (p≤0.05) in the morphological traits of the treated plants when compared with the control. Overall, 2.0% vinka alkaloids concentration resulted in higher average plant height by 193.8 ± 1.86, leaf area increments by 88.6 ± 5.1 (left leaf), 115.1 ± 4.7 (middle leaf), 86.2 ± 3.8 (right leaf) and the dry seed weight by 1.7 ± 3.6. The improvement of the traits is concentration dependent and increases with increment in vinka alkaloids concentration. Thus, we suggested that 2.0% concentration should be employed in improving Sword bean growth and yield.

Abstract

Fungal diversity is high in Indonesia, one of which is Scleroderma sp. Scleroderma forms a symbiotic relationship with Gnetum gnemon. Its fruiting body is puff-ball shaped, and its gleba can be consumed because of its taste and nutritious. Study on the Scleroderma’s diversity in Purworejo Regency has not been done. In this study, morphological characteristics were used as main identification character. Scleroderma samples were collected from Grabag, Kemiri, and Kaligesing and then observed their morphology and spore characteristics. Morphological traits observed on fruit body shape (globose and kidney-shaped); and ornamentation on peridium layer (cracked, nodule and peeling). Chemical content, temperature, and humidity of the soil were also observed as supporting data.

Abstract

Baturraden Botanical Garden located on the slopes of Mount Slamet in the south has a high enough humidity so it is ideal for plant growth, especially orchids. As an ex-situ plant conservation area, the Baturraden Botanical Garden plays an important role in preserving the diversity of orchids in it. The purpose of this study was to find out the types and descriptions of terrestrial orchids in the Baturraden Botanical Garden area of Central Java. The method used in this study is a 400 m line transect method with an inter-point distance of 100 m each and data collection is carried out at 10 m each on the right and left of the line transect.  Hasil research shows that there are 13 species derived from 10 genus of soil orchids. The types that have been found are Goodyera rubicunda (Blume) Lindl., Calanthe pulchra (Blume) Lindl., Spathoglottis plicata Blume, Cryptostylis javanica J.J.Sm., Appendicula alba Blume, Phaius callosus (Blume) Lindl., Lepidogyne longifolia Blume, Tainia elongata J.J.Sm., Goodyera colorata Blume, Malaxis sp. Soland. ex Sw., Goodyera sp. R. Br., Goodyera procera (Ker-Gawl.) Hook., and Plocoglottis sp. Blume.
