Abstract

The objective of this research was to know the concentration of Pb, Cr, and Hg in Fish in the Ciliwung River. The observation of Heavy Metals concentration in Fish showed that only Hg in internal organ of Demersal Fish was significantly different according to the location and replication (P < 0.05), while Heavy Metals of Pb and Cr in Demersal and Pelagic Fish were not different according to the location and replication. It means that human activities such as industrial, settlement, agriculture and transportation along the Ciliwung River affect adsorption/absorption of Hg by Fish. Generally, Pb, Cr, and Hg concentration in the internal organ of Demersal and Pelagic Fish were higher than in the Fish Meat, because internal organ are the target organ of Heavy Metals substances in Fish. In general, metal concentrations of Pb, Cr, and Hg in the meat and organs of Demersal Fish were higher than that in the meat and organs of Pelagic Fish. This was due to the activity of Demersal Fish that forage and are active in bottom waters close to sources of heavy metal pollutants (sediment). The Result of observation show that in general, the contribution of human activities in the DKI Jakarta area to the presence of Pb, Cr, and Hg in the waters, sediment and Fish of the Ciliwung River was greater than in the Bogor and Depok areas.

Abstract

Indonesia is a newly developing country, with many problems, one of which is health problems related to medicinal ingredients (antibiotics). Many microorganisms, especially bacteria, are resistant to various types of antibiotics. Various efforts have been made by the government to find new antibiotics, to reduce the use of semisynthetic or synthetic antibiotics which are very dangerous. One of them uses macrofungi.The antibacterial activity of eight species of macrofungi (Ganoderma applanatum, G. boninense, Ganoderma sp1, Ganoderma sp2, Trametes sp1, Trametes sp2, Trametes sp3, Microporus xanthopus and Suillus sp1) against Escherichia coli and Staphylococcus aureus has been carried out, using the diffusion method. The results showed that six species were able to inhibit the growth of Staphylococcus aureus. The species were Ganoderma applanatum, Ganoderma sp1, Trametes sp.1, Trametes sp.2, Trametes sp.3, and Suillus sp. The resulting limiting zone ranged from 6.5-11 mm. The zone of inhibition produced by Trametes, the smallest inhibition zone of Ganoderma sp1. The higher the concentration of the extract, the greater the ability to inhibit the growth of the test bacteria.

Abstract

Seagrass is a shallow waters ecosystem. Research on the structure of the seagrass community has been conducted on Semak Daun Island and Kotok Kecil Island, Thousand Islands, Jakarta. Semak Daun Island includes the residential zone where is a lot of human activity, and Kotok Kecil Island is a part of the utilization zone. This study aimed to determine the structure of the seagrass community on Semak Daun Island and Kotok Kecil Island. Data were collected using the line transect and quadratic methods; one island is divided into 4 stations that are assigned into 3 transects with 25 m length from each station, and 50 meters straight line is drawn from each transect, and a plot 1 x 1 m is laid out every 10 meters. The results showed that the species composition on Semak Daun Island (4 species, 2 families) was higher than on Kotok Kecil Island (2 species, 2 families). The Similarity Index between the two islands was at the same level. The seagrass diversity index on Semak Daun Island was in the medium category, and the diversity of seagrass species on Kotok Kecil Island is low. Frequency, Density, Coverage, and Important Value Index on both islands were the same, Thalassia hemprichii had the highest yield compared to other species on both islands, whereas the smallest on Semak Daun Island was Halophila ovalis and the smallest on Kotok Kecil Island was Halodule uninervis.

Abstract

Butterfly observation research in the Arboretum City Forest area has been widely known, but research related to interaction of butterflies and flowering plants is still scarce. The Aim of this study was to determined the interaction of butterflies and flowering plants in the Cibubur Arboretum City Forest area. We found 45 species, 4 families with 232 individuals, which consists of four butterfly families, includingPapilionidae, Pieridae, Nymphalidae, and Lycenidae. The results of this study are different from the results ofresearch conducted in 2014. We found that the number of individuals and species are decreased. Based on the diversity index value in 2014, and current situation,has a similar moderate category diversity index. This can be due to the presence of the same feed plants and host plants in this area. Several types of flowering plants were found at the research site: Asystasiagangetica, Emilia sanchofolia, Synedrella sp., Kyllingasp., and Mimosa pudica. There are some of the same plants found in both opened and closed habitats such asPolyalthialongifolia, Diffenbachiaseguine, Cecropianpeltata, Parkiaspeciosa , and Swieteniamahagoni. The butterfly species Leptosianina is one of the species found in high numbers in the Arboretum City Forest area, due to the many host plants found in this area. The correlation analysis showed a strong relationship between flowering plants and the number of individual butterflies in both habitats (opened and closed). The Asystasyagangetica plant is widely used by butterflies as a food source

Abstract

Karamunting (Rhodomyrtus tomentosa Aiton) (fam: Myrtaceae), also called Ceylon cherry, downy rose myrtle, is native to South Asia. It treats diarrhea, dysentery, leukorrhea, hemorrhoids, toothache, infection and bleeding after childbirth, heart, and clears cholesterol. The research was conducted between April and August 2016 in South Sumatra in Padamaran and Tanjung Batu Villages and West Kalimantan in Kawat, Karamunting, and Capkala Villages analyzed the distribution of the karamunting plant and its secondary metabolites. Purposive sampling with the transect method was used. The observation variables analyzed included the species present, the number of individuals of each species, height, DBH, and coverage area. Species Composition, Relative Density (KR), Relative Frequency (FR), Relative Dominance (DR), and Important Value Index (INP) were all instrumental to the data analysis calculation. The findings indicated that there were 48 seedlings and 19 sapling species. The density and frequency were greater than that of other plants at the growth rate of seedlings and saplings. While the distribution was dominant in the Capkala Village, the most abundant phenol of karamunting leaves was discovered in Tanjung Batu Village, plentiful flavonoids in Padamaran Village, and the highest saponins and tannins in Karamunting Village. Furthermore, tannin was plentiful in Capkala Village.

Abstract

In Indonesia, every concession of industrial plantation forest must leave at least 10% from the size of the concession as natural forest and set aside for protected area. We examined the forest structure and composition through a one-hectare permanent sampling plot (PSP) within three forest cover classes, open land, scrub and young regeneration forest. Surveys showed that there were 143 trees (>10 cm dbh) of 23 species in the Open Land PSP (dominated by Euphorbiaceae, Myristicaceae and Rutace families), 407 trees from 48 species in the Scrub PSP (Euphorbiaceae, Lauraceae and Sapindaceae), and 486 trees from 67 species in the Young Regeneration Forest PSP (Euphorbiaceae, Lauraceae and Annonaceae). Biomass and carbon stock determined through the trees ≥ 10 cm dbh in each forest cover classes. With a Chave formula found that in Open Land stored 15.6 ton C/Ha, in Scrub stored 63.4 ton C/Ha, and in Young Regeneration Forest stored 83.8 ton C/Ha. Calculated that there is around 4.7 million ton C stored in those various forest and vegetation covers within conservation area inside plantation forest concessions at landscape scale. This can be contributed to the efforts of emission reduction at the sub-national level.

Abstract

Indonesia has abundant natural resources. Natural resources can be used as medicinal herbs. The use of natural resources using medicinal plants (medicinal herbs) has existed for a long time. Medicinal plants are spread all over Indonesia. The urban forest of Sanga Buana Cilandak in South Jakarta is widely used as a place for conservation, education and nature-based tourism, and is selected as a research site because it is used by local people for food and medicine. The purpose of this study was to identify which plants were used as medicines by people in the Sangabuana area. Survey data collection is based on the results of surveys obtained through direct interviews with the community at the destination. Interviews were conducted using a purposive sampling method. Purposive sampling is sampling that is limited to a specific target group. We interviewed seven respondents working in the urban forests of Sangabuana. Our research has revealed 56 species of medicinal plants belonging to 30 families. The most commonly used part of the plant as a medicine is the leaves, and the most common processing method is boiled. Based on utility value (UV) and fidelity level (FL) calculations, red ginger (Alpinia purpurata) UV is shown to have 1.43 and FL to be 100%.

Abstract

Macroalgae is a marine biological resource that has the potential to be developed because macroalgae have an important role both in terms of ecology and economy. But anthropogenic pressures such as domestic waste, solid waste disposal, urban community activities, urban planning development activities, and community activities in the waters tend to affect macroalgae growth and diversity which even cause damage to the extinction of macroalgae species. This research needs to be done as the limited information about macroalgae on Rambut Island. The purpose of this study was to determine the composition, and diversity by inventorying and describing the types of macroalgae and to analyze the state of the macroalgae community structure in the Rambut Island waters. Data and information on types and descriptions of macroalgae morphology can be used as a basis for managing and enriching macroalgae biodiversity, especially on Rambut Island, Kepulauan Seribu. The methodology is the quadratic transect method. The results obtained 28 species belonging to 3 divisions, namely 18 species of Chlorophyta, 5 species of Phaeophyta, and 5 species of Rhodophyta. The diversity index of macroalgae is moderate (1.73) and there are no dominant species. The quality of the waters in Rambut Island supports the growth of macroalgae. The macroalgae community structure in Rambut Island is still in a stable condition.
