Abstract

Celosia argentea Linn. is a herbaceous plant of Amaranthaceae family. The plant has antioxidant property. The antioxidant capacity is determined by the existence of secondary metabolite of which phenolics compound is one of them. This research aim was to determine the correlation between phenolics compound content and the growing environment with the antioxidant activity of Celosia argentea Linn. The plants were obtained from three different locations in Salatiga area included Ngronggo Village Landfill (TPA), Jalan Raya Lingkar Selatan (JLS), and in Blotongan Housing Complex areas (PB). The fresh leaves of the plant were extracted by maceration method using ethanol 96% in the room temperature for 48 hours. The determination the phenolics content was using Folin-Ciocalteu method, while antioxidant activity using DPPH assay. The phenolis content of C. argentea Linn. leaves were 10,22; 6,99; 4,97 ppm from TPA, JLS, and PB respectively, while the IC50 values of antioxidant activity were 2,98; 3,18; and 3,35 ppm respectively. There were a correlation between antioxidant activity and phenolics compound with the growing environment of C. argentea Linn. The higher of phenolics compound content, the lower the IC50 value (higher an antioxidant activity). The phenolics content was also has a strong correlation with environment.

Abstract

Insects are invertebrate animals with diversity and have a high adaptability. Insects have properties that are very sensitive to light, especially night insects. Night insect species in the Liwa Botanical Garden (KRL) have not been identified. This research was conducted from October to November 2019 in the Liwa Botanical Garden, West Lampung Regency. The purpose of this study was to determine the effect of the color of the lights (red, yellow, blue and white) on the presence of night insects on KRL. This research was conducted using the Purposive Sampling method using red, yellow, blue and white light. The insects that were caught were identified in the Zoology Laboratory of the Faculty of Mathematics and Natural Sciences Unila and analyzed descriptively based on morphological similarities with the book Borror et al., (1992). The data obtained were analyzed using the ANOVA test using Minitab 19. The results of this study showed that in the Araceae area of the Taman Liwa Botanical Garden the blue light traps caught a maximum of 457 night insects while the red light traps caught the night insects with the least number 19 tail. This study also showed that light intensity correlated with the number of night insects obtained.

Abstract

Sayung Subdistrict is a densely populated area and has many industrial areas. It was expected that it has produced pollutant waste that enter the aquatic environment. The existence of these wastes can affect the quality of the waters and lives therein. This study aims to determine the quality of the waters by assessing the structure of the macrobenthos community temporally and spatially which are related to the physical-chemical parameters of the water. The data collection of macrobenthos and substrate waters were carried out at 5 station considered as represent variety of waters bodies in Sayung. Samples were taken 2 times, in dry season and rainy seasons. Water parameters measured including DO, salinity, pH, turbidity, and temperature, while sediments are analyzed for the grain size of sediment and organic matter content. The results from macrobenthos analysis found 20 species. The most commond macrobentos found Metapenaeus monocerus, Cerethidea cingulata,Telescopium telescopium and Sesarma sp. Macrobenthos diversity index ranges from 0.59 to 1.76; Evenness index ranges from 0.78 to 0.96; and the dominance index ranges from 0.19 to 0.59. Diversity index value include the moderate criteria, which indicates a disturbance in Sayung waters. The results of multiple linear regression test showed that DO-silt parameter has a strong influence on the abundance of macrobenthos. The abundance of species Cerithidea cingulata at the research site can be used as bioindicators of contamination organic matter. Generally these waters still supports aquaculture

Abstract

Mojo Mangrove is a forest area located in the tidal area and becomes a habitat for various organisms in it. Mojo mangrove forest is an ecosystem that is a place to live and breed various species of birds, because of the existence of habitat and food that supports. The location of the Mojo mangrove forest which is far from the settlement is a supporting factor which is the reason birds love the habitat. Species diversity and abundance of bird species can reflect the high biodiversity of other wildlife, meaning birds can be used as indicators of forest quality. The purpose of this study was to determine the diversity and abundance of bird species, and determine the status of bird conservation in the Mojo Pemalang Mangrove Restoration Center. The study was conducted from February to April 2019 at the Mojo Mangrove Restoration Center in Pemalang District, using the point count method. The analysis carried out was a species abundance index, a species diversity index, a species evenness index, a similarity index, and the Hutchinson T test. There are 53 species of 27 families. The diversity of bird species is included in the medium category with an index of 1.97 - 2.85. Based on IUCN, there are 49 species of birds included in the Least concern category, 2 species included in the vulnurable that is Javan coucal (Centropus nigrorufus) and Javan myna (Acridotheres javanicus), 2 species included in the Near threatned category that is Oriental darter (Anhinga melanogaster) dan Javan plover (Charadrius javanicus). Based on Law No. 5 In 1990 there were 10 protected bird species.

Abstract

Cry proteins of Bacillus thuringiensis have been successfully used as biopesticides and transgenic crops throughout the world. However, resources against the most serious agricultural pathogens, plant root-knot nematodes, are limited. Nematicidal Cry proteins produced by Bacillus thuringiensis (Bt) are used for effiecient pest control. Cry 5, Cry 6, Cry 21, and Cry 55 were known to have nematicidal activity. In the present study, 80 Bt isolates from diverse locations in Thailand have been investigated for their nemeticidal cry gene content. Bt isolates were screened through Sodium Dodecyl Sulphate-Polyacrylamide Gel Electrophoresis (SDS-PAGE), Polymerase Chain Reaction (PCR), ligated into the cloning vector PJET 1.2/blunt, transformed into Escherichia coli DH5ɑ, and diagnostic restriction enzyme digest for the presence of nematode-active cry genes. Of 80 Bt Thai isolates, 24 isolates (30%) have 54-kDa protein which is similar with the molecular weight of Cry 6 protein and 5 isolates (6%) have ±45 kDa protein which is similar with the molecular weight of Cry 55protein. Only one Bt isolate (Bt 32) was suspected to be positive for the presence of cry 6 gene.

Abstract

Hemidactylus frenatus has 2 color morph, those  are dark morph and light morph. This gecko also has the ability to change it’s body color  from one morph to another. This ability is usually associated with thermoregulation effort or camouflage for defense. This research attempts to assess the camouflage of the house gecko on various habitat type (building and garden) that exist on UGM campus. By employing CBIR method, it is found that this gecko has high similarity with it’s surrounding, either on the light background (building) or dark background (garden). This is shown by the Euclidean distance value at 0.36 on the gecko that lives on the buildings, and 0.13 on the gecko that lives on the garden. According to the observation and literature study, it is found that the rapid color change ability on this gecko is not related to thermoregulation but more likely associated with camouflage. The type of camouflage strategy employed by Hemidactylus frenatus is background matching

Abstract

Diversity studies and important value indices have been carried out on forest vegetation in the Mount Merapi National Park area using the Quadrat Sampling Technique method. The specified plot size is 6x6m2. There are 2 plots used. Forest diversity in the Mount Merapi National Park is determined using the Shannon diversity index formula. The results show that the species diversity index of moss-lichen habitus and stand habitus is 0, which means that these two habitus have no diversity. Both of these habitus have only one species that grows in the study area, while the species diversity index in shrub habitats was 0.426673041. Habitus which has the highest species diversity index is herbal habitus which is 0.734014356. In this study found as many as 12 species consisting of one species of moss-lichen habitus, 7 species of herbaceous habitus, 3 species of bush, and one stand habitus species. The highest important index value for moss - lichen habitus is Diphasiastrum sp. (300%), Viburnum sp. for herbal habitus (100.96%), Carex sp. for shrub habitus (132.63%), and Acacia sp. for stand habitus (300%).
