Abstract

Banyak Angkrem and Kedung Kopong are medium lowland tropical rain forest areas where many types of orchids can be found. This study aims to determine the types and diversity of orchids found in the area of ​​Banyak Angkrem and Kedung Kopong. Data was collected using the Visual Encounter Survey (VES) method with a radius to the right and to the left 5 m from the observation path with a research area ​​6.24 ha. The results showed that in the two areas found 15 species of orchids consisting of 10 species of epiphytic orchids (Acriopsis lilifolia, Agrostophyllum laxum, Bulbophyllum sp 1, Bulbophyllum sp 2, Dendrobium sagittatum, Dendrobium sp, Oberonia lotsyana, Pholidota sp, Polystaschya concreta, Vanila. planifolia) and 5 species of terrestrial orchids (Geodorum densivelorum, Malaxis ophrydis, Malaxis sp, Nervilia plicata, Perystilus goodyroides). The level of diversity (H ') of orchids in the two regions is classified as moderate with an H' value of 2.22

Abstract

Maluku is known as an archipelago and has high biodiversity. One of the many islands in Maluku that has biological natural resources is Marsegu Island in the West Seram district. Marsegu Island has a very high diversity of marine resources, various types of birds and various vegetation diversity of trees. The diversity of trees in vegetation shows a variety of compositions, both variations in shape, structure or morphology, color, number, and other characteristics of plants in an area. Tree vegetation is the main constituent of forest areas and has an important function in water management, germplasm reserves, life support, development resources and sources of foreign exchange. This study aims to determine the diversity and dominance of protected forest trees on Marsegu Island, West Seram district. The method used in this research is the belt transect method. Furthermore, the tree species were identified based on the identification book. Data were analyzed using the diversity index formula from Shannon-Wienner and Simpson dominance index. The results of research conducted in the eastern and western parts of Marsegu Island found 22 species of trees as the protected forest on Marsegu Island. The Diversity Index at both stations is in the medium category with the results obtained that the east station is 2.2652 while the west station is 2.3761 and is in a stable condition, while the Dominance Index at both stations is low with the results obtained that the eastern station is 0.1618 while the west 0.1135 and no species dominates.

Abstract

The Bunder Reservoir Ecosystem is composed of various components, both biotic and abiotic. One of the components contained in the reservoir is aquatic plants as phytoremediator for wastewater. The aquatic plant inventory in the Bunder Reservoir aims to determine the diversity of aquatic plant species that have the potential to phytoremediate industrial waste. The research design was descriptive qualitative exploratory. Aquatic plant species were collected using a subjective estimates method with visual techniques. In the waters of the Bunder Reservoir, 17 species of aquatic plants from 13 families were found, including 11 emergent types, 1 free floating, 4 rooted floating, and 1 submersed. Types that have the potential to act as phytoremediators for inorganic waste in the metal categories are A. philoxeroides, A. sessilis, Cyperus sp. Hygrophila sp., I. carnea, I. aquatic, L. perpusilla, N. nucifera, Nymphaea sp., N. indica, P. barbata, and T. latifolia. The aquatic plant that has the potential for phytoremediator of pesticide waste is L. adscenden. While S. sesban tends to remove oil pollutants. Organic waste degrading species consist of T. latifolia, L. perpusilla, I.aquatica, Cyperus sp., And Brachiaria sp

Abstract

Study on the nematode parasite species of Bunomys spp. from Mekongga Mountain, Southeast Sulawesi was conducted on deposited specimens in Museum Zoologicum Bogoriense, Zoology Division, Research Center of Biology-LIPI. Bunomys is endemic genus murine rodent in Sulawesi. This study aims to determine the types of nematodes in endemic Muridae rodent, the results of which can help the government in developing disease management plans. The nematodes identified in this study were Subulura andersoni (host: B. andrewsi), Syphacia rifaii (host: B. chrysocomus), Cyclodostomum purvisi (host: B. penitus), Heterakis spumosa (host: B. chrysocomus). Except for Sy. muris, all of the recorded nematodes have worldwide distribution. Morphology and taxonomy of nematodes will be discussed in this paper

Abstract

This study aims to determine the effect of altitude on the phytochemical and antioxidant content of sawi langit (Vernonia cinerea L.) root. Sawi langit is a herbaceous plant that has potential as a medicinal plant. This plant can thrive in the tropics. In this study, sawi langit were taken from three altitudes, namely <400 masl, 401-800 masl and >801 masl in the Banyumas, central Java. The sample used was sawi langit root which was extracted using 3 types of solvents (methanol, ethyl acetate and n-hexan). Phytochemical tests showed positive results of the content of flavonoid, alkaloids, tannins, terpenoids and saponins compounds in the extract of sawi langit root from the three altitude with differences effectiveness of each solvent. At an altitude of <400 masl and extraction using methanol resulted strong antioxidant activity with an IC50 value 78.56 ± 3.2  μg/ml compared to an altitude of 401-800 masl and >801 masl

Abstract

The condition of eating places such as street vendors will determine the level of food hygiene, including the water used to wash food utensils. This study aimed to determine the number of microbes and identify Escherichia coli and Salmonella sp. on the water that was used to wash tableware by street vendors around UIN Sunan Ampel Surabaya. Water samples before and after being used to wash tableware were obtained from 4 street vendors. The number of microbes in the sample was tested by the Total Plate Count (TPC) and Most Probable Number (MPN) methods, Escherichia coli was identified using Eosin Methylene Blue Agar (EMB) media, and Salmonella sp. was identified using Salmonella-Shigella agar (SSA) and Triple Sugar Iron agar (TSIA) media. Based on the results of TPC test, the water sample before being used to wash tableware had the lowest and highest values that were 3.0 x 102 Cfu/ml and 9.8 x 105 Cfu/ml, respectively, while the water sample after being used to wash tableware had the lowest and highest values that were 4.0 x 102 Cfu/ml and 3.5 x 105 Cfu/ml, respectively. In the MPN test, the water sample before being used to wash tableware had the lowest and highest values that were 15/100ml and 26 100/ml, respectively, while the water sample after being used to wash tableware had the lowest and highest values that were 72/100 ml and 271/ 100 ml, respectively. Escherichia coli was detected in all samples 1&3 while in sample 2 Escherichia coli was detected in the water before it was detected the genus Enterobacter and in samples 4 the genus Enterobacter was detected and all samples water used to wash tableware of street vendors was positive for Salmonella.
