Abstract

The diversity of bird species can reflect the high biodiversity of an area. it means that birds can be used as a bio-indicator of environmental quality. Determining the quality and level ofenvironmental damage can be seen from the diversity of bird species in the region. Environmental quality will be better if the diversity of bird species in the region is diverse.Birds have an important role in protecting the ecosystem in the Liwa Botanical Garden. The presence of birds in the Liwa Botanical Garden has not been well identified. Therefore thisresearch needs to be done. This research was conducted on 12 October 2019 to 20 October 2019 in the Liwa Botanical Garden, West Lampung. Data collection of bird species isconducted in the morning at 06.30.00-08.30 West Indonesia Time and afternoon at 16.30-18.00 West Indonesia Time, with a combination of the count point and the transect method then all encounters with birds are recorded and identified directly at the study site. After the birds are identified, data is processed to find out Shannon's level index and diversity index. The species diversity index uses the Shannon and Weiner formula. The level of diversity is determined based on the species diversity index. The results showed that there were 15 bird species with a total of 466 individuals with a moderate diversity  index and an evenness index indicating a distressed community.

Abstract

Grasshopper is one of the diurnal cosmopolitan insect, the existence of grasshoppers is very influential for some other animal populations such as birds. It is still lack of information of diversity, distribution, population, and other basic biological aspects of grasshoppers at Kebun Raya Liwa (KRL). To monitor biodiversity, it is necessary to provide informations about the number of individuals, their functions, and roles in the habitat and ecosystem. Therefore it is necessary to conduct the research of these topics. This research was carried out during November to December 2019, at the Taman Hias Kebun Raya Liwa. Grasshoppers were cached in the morning from 06.00 AM to 09.00 AM, day from 10.00 AM to 02.00 PM, and afternoon from 03.00 PM to 06.00 PM . The grasshoppers was cached using a sweeping net by exploring the Taman Hias Kebun Raya Liwa. The caught grasshopper was identified at the Zoology Laboratory of the Faculty of Mathematics and Natural Sciences, Universitas Lampung. The result show that ten species of grasshopper were found at the Taman Hias Kebun Raya Liwa, i.e. Phaleoba antennata, Phaleoba fumosa, Phaleoba rustica, Atractomorpha crenulata, Atractomorpha sp., Phillium crurifolium, Phillium sp, Trilophidia annulata, Oxya chienensis, and Melanoplus differentialentialis. The index diversity of grasshopper at the Taman Hias Kebun Raya Liwa is categorized to moderate with H' = 2.223. The best time to catch grasshoppers is in the morning from 06.00 AM-09.00 AM and afternoon from 03:00 PM – 05:00 PM.

Abstract

Problems in decreasing coffee production one of them caused by plant pests attack. Countermeasures using pesticides and disinfectants are not effective because they have long effects and ruining the environment also pest resistance. It is necessary to prevent a more environmentally friendly way by utilizing a natural enemy in the form of a microorganism, the genus Bacillus. Lipase can hydrolyze lipids so that it can be used to degrade lipid substrates that compile the body structure of pests and diseases. This research aims to detect the lipolytic activity of Bacillus isolates from coffee plantations. The results of this research obtained 3 isolates of Bacillus namely T1, T2, and T3 which have differences in cell configuration and variations in the location of endospores. Furthermore, Bacillus isolates were detected lipolytic activity by growing isolates on lipase selective medium. Isolates that have the largest lipolytic activity are T2 isolate codes with an average index of 6.01 and the lowest lipolytic activity, namely, isolate T1 codes with an average index of 4.58.

Abstract

The diversity of freshwater fish in Way Sindalapai River is quite abundant but there has not been much study on the diversity of fish in Way Sindalapai River. This study aims to determine the diversity of freshwater fish species in Way Sindalapai River, Liwa Botanical Garden. The study began with a preliminary survey with a purposive sampling method and sampling was carried out at 3 sampling locations. The tools used in this study include fishing nets (gill nets), fishing rods, scoop, traditional fishing gear (raas), Global Positioning System (GPS), rulers, and cameras. The sampling points include upstream, middle, and downstream areas. The method used in sample identification is by measuring the morphometry of the samples directly at the sampling location which includes total length, standard length, head length, and height, and collection of fish samples photos. Research parameters and data analysis include environmental factors, the diversity index, the evenness index, and the dominance index. The results showed that 170 fishes were found, 8 species, 2 families, and 4 genera. The fish diversity index in the Way Sindalapai river is included in the medium category from the Shanon-Wiener index calculation results, starting from the upstream, middle, downstream, respectively 1.37; 1,34 and 1,22. Evenness index at all locations are included in the low category from the Shannon-Evenness index calculation results, respectively 0.16; 0.14; and 0.12. The dominance index at all locations is included in the low category based on Simpson's dominance index, which has a value of 0.35; 0.32; and 0.28. Based on the conservation status of the IUCN Red List, ichthyofauna in the Way Sindalapai river is 5 species of low risk (least concern) namely Barbodes microps (wader goa), Rasbora bunguranensis (seluang), Barbodes binotatus (wader cakul), Thynnichtys thynnoides (lumoh), Channa striata (bogo). One species that is critically endangered is Rasbora tawarensis (depik), and two species are lacking information (data deficient) namely Rasbora sumatrana (seluang), and Rasbora semilineata (seluang)
