Abstract

Forest parks can take a role in mitigating negative impact of Urban Heat Island. Therefore, this study was conducted to clarify ecological function of three forest parks i.e Ganesha, Maluku, and Tegalega forest park in mitigating Urban Heat Island. Land classification and surface temperature were determined by analyzing Landsat 8 image with QGIS. Air temperature was measured by mobile station through north-south and east-west of Bandung City area. There are four types of land classification in Bandung as follows: settlements, water body, bare soil, and vegetation. In Bandung City, vegetation cover is around 20.72%; surface temperatures in the afternoon varies from 23 to 39.6°C, while during the night air temperatures varies from 20.5 to 24.9°C. Northern part of Bandung tends to have cooler air temperature due to high coverage of vegetation. Tegalega forest park can reduce temperature up to 2.6°C, while in Maluku forest park is 1.98°C and Ganesha forest park is 0.75°C. Therefore, the existence of forest parks is important in urban area because they can take a part to reduce negative impact of Urban Heat Island.

Abstract

Madura island is known as a mixed deciduous forest area with dry seasons and limestone soil. The island has unique plant species compared to the mainland Java. However, most of the mangrove forest areas have been converted into ponds and housing. One of the remaining mangrove swamps is located at Telang Asri village, Kamal Subdistrict, Bangkalan Regency. Several species of mangroves have been reported here, along with other groups of plants from the Phyllanthaceae family, found numerously at the time of observation. In 1963, CA Backer and RC Bakhuizen van den Brink Jr. have already listed 16 species of Phyllanthaceae from Madura Island. Since then, the updated information on the Phyllanthaceae of Madura has not been available. Therefore, this study aimed to collect the members of Phyllanthaceae family in the mangrove swamp areas of Telang Asri village. The field study was carried out using the exploratory method, while specimen preparation was conducted in Herbarium Bandungense (FIPIA). In this study, seven species were collected from Telang Asri, namely Glochidion littorale Blume, G. zeylanicum (Gaertn.) A. Juss., Phyllanthus amarus Schumach. and Thonn., P. debilis Klein ex Willd., P. reticulatus Poir., P. urinaria L., and P. virgatus G. Forst.

Abstract

This research aimed to confirm the predator avoidance behavior of mice from snake droppings as a stimulant. Snake droppings are obtained from snakes fed with mice that come from the same strain as the mice being tested for response. Snake droppings were diluted into three different concentrations (25%, 50%, and 75%). The results showed that male individuals tend to avoid the odor stimuli than the female, it’s shown by the higher avoidance duration in males than the females. The results also indicate that innate behavior takes role in the avoidance response since the mice have never been exposed to any presence of predator.

Abstract

Indonesia is a biodiversity country and has much of samples of bioacoustics but there are no bioacoustics data collected and saved to be referred. Bioacoustics is a study of frequency range, sound amplitudo intensity, sound fluctuation, and sound patterns. It is very useful to study more about population presumption and species determination. This insect bioacoustics research is done at Gunung Gede Pangrango National Park and aims to analyse variety of sound frequency of cicada and cricket. Methods which are used are recording the sounds, editing and analyzing the record result with Praat and Raven Lite 2.0 softwares, and analysing the environment. Analysing the sounds which is done is to find miximum frequency, minimum frequency, and average frequency. The result of the sounds analysis is compared to database in Singing Insect of North America (SINA). Environmental analysing includes temperature, air humidity, and light intensity. There are nine cicada sound recording files and twenty four cricket sound recording files. Cicada has high sound characteristic (9,168.2 Hz) and cricket has low sound characteristic (3,311.80 Hz). Comparation to Singing Insect of North America (SINA) database shows that the cicada’s sound is resemble to Tibicen marginalis and the cricket’s sound is resemble to Grylodes sigillatus.

Abstract

Endophytic fungi isolated from red ginger (Zingiber officinale) can inhibit growth of Fusarium oxysporum, but the ability of the fungi to control Candida albicans as human pathogen has not been reported. The aims of this research were to study the mechanism of ten endophytic fungi isolates derived from red ginger to control C. albicans in vitro using dual culture methode and fungal extract, and to determine fungal bioactive chemical groups produced by the fungi. Three out of ten isolates tested, Talaromyces assiutensis JMa 7, T. assiutensis JMbt 3, and Curvularia affinis JMbt 9 inhibited growth of C. albicans with inhibition zones were 4.0 mm, 4.9 mm, and 11.3 mm, respectively. The cultures of the three potential endophytic fungi were extracted by maceration method using 3 solvents i.e ethyl acetate, n-hexane and ethanol. The three isolates were grown in PDB separately for 21 days incubation. At harvest, the culture filtrate was extracted by ethyl acetate and n-hexane, while fungal mycelia were extracted by all the three solvents. Ethyl acetate extracts obtained from culture filtrate of all the three fungal isolates consistently inhibited C. albicans with inhibition zones were 2.0-3.8 mm. For n-hexane extract, however, only Talaromyces assiutensis JMbt 3 that had positive effect with inhibition zone was 2.0 mm. All extracts from mycelia did not have any effects on C. albicans. The ethyl acetate extract of T. assiutensis JMbt 3 was analysed to determine its chemical groups using visible color on thin layer chromatography (TLC). The results showed that the bioactive compounds was terpenoids, and antioxidant.
