Abstract

Diatoms or phytobenthic are often used as bio-indicators of water quality in freshwater ecosystems such as rivers, but have never been used for monitoring the quality of artificial water ecosystems. The objective of this research is to use the diatom as a bioindicator for measurement the success of phytoremediation process of irrigation water that has status hyper-eutrophic and is polluted from organic materials using polyculture of various local hydromacrophytes through batch culture system. This experimental study was conducted in a greenhouse through planting some local emergent, submerged and floating leaf hydromacrophytes on a 30 L bucket with a given substrate from sand and gravel. The experiment used a completely randomized design with two treatment included phytoremediation model and control in the form of substrate without hydromacrophyte which repeated three times at the same time. The success of phytoremediation model was determined through some biotic diatoms indices (Percentage Pollution Tolerant Value/%PTV, Tropical Diatom Index/TDI and Shannon Wiener Diversity Index) as bioindicator and the improved water physics chemical quality on days 0, six, and 13 after incubation. The results showed that phytoremediation process using polyculture hydromacrophytes through batch culture system for 13 days significantly improving the quality of irrigation water. Based on some biotic diatom indices, the water was improved from heavily organic pollution to moderately organic pollution (%PTV), from hypereutrophic to become eutrophic (TDI) and from moderately polluted become slightly polluted (Shannon Wiener Diversity Index). This results also supported from water physico-chemical parameters. Poly-culture of some local hydromacrophytes for six days significantly decreased the organic matter content of irrigation water was reflected from the decrease concentration of Biochemical Oxygen Demand/BOD (14.79 mg/L to 3.61 mg/L), Total Suspended Solid/TSS (14.6 mg/L to 0.08 mg/L), turbidity (19.97 NTU to 1.46 NTU), nitrate (1.44 mg/L to 0.03 mg/L), orthophosphate (0.24 mg/L to 0.042 mg/L), Total Kjeldahl Nitrogen (TKN) (0.93 mg/L to 0.68 mg/L), and free chlorine (0.09 mg/L to 0.05 mg/L), while concentration of Chemical Oxygen Demand (COD) decreased significantly 13 days after incubation from 48.3 mg/L to18.2 mg/L.

Abstract

Refractory and mortality associated with status epilepticus (SE) were correlated with the degree of inflammation-induced neuronal cell death. This study was aimed to investigate the correlation of oxidative stress (Malondialdehyde, MDA) and inflammation (C-reactive protein, CRP) process with neurodevelopmental outcome in children after the episode of convulsive type SE. This study was designed as cross sectional which included 26 convulsive type SE subjects and 15 control subjects. MDA level was measured by thiobarbituric acid (TBA) method, while CRP level was measured by ELISA method. Neurodevelopmental outcome was measured by Bayley-III Scale of Infant and Toddler Development 3 month after the convulsive type SE episode. Results showed that both MDA (independent t-test, p < 0.05) and CRP (Mann-Whitney test, p < 0.05) level was significantly higher in convulsive type SE group as compared to control group. Further analysis also showed that MDA (Spearman correlation test, p = 0.000, r = 0.756) and CRP (Spearman correlation test, p = 0.000, r = 0.835) level was positively correlated with convulsive type SE. In convulsive type SE group, MDA level was negatively correlated with neurodevelopmental outcome but CRP was not. We concluded that MDA level was negatively correlated with neurodevelopmental outcome in children with convulsive type SE, but CRP was not.

Abstract

Dischidia is an epiphytic plant, it is used as herbal medicine and has economic value. In addition, Dischidia also has an ecological function. Moreover, some species of Dischidia are endemic in a particular region. Various forest types occur in Bangka Island serves as natural habitat for this epiphytic plant. This research aimed to record the diversity and abundance of Dischidia and analyze those environmental factors which affect its abundance. The research was conducted in August – September 2016 at Bangka Island. Three plots of 20 × 20 m² were placed with a minimum interval of 50 m in the habitat where Dischidia are found. The species diversity and abundance of Dischidia as well as abiotic factors such as temperature, humidity, light intensity, wind speed, and altitude were recorded in these plots. The vegetation structure was analyzed based on index of diversity, index of dominancy and index of evenness. Data on the environmental condition and abundance of Dischidia were then analyzed using Canonical Correspondence Analysis (CCA) method with Canoco 4.5 software. Five species of Dischidia were found in Bangka Island that are Dischidia bengalensis, Dischidia imbricate, Dischidia nummularia, Dischidia rafflesiana, and Dischidia hirsute. Dischidia is found in 14 species of host plants. D. imbricate (23 individual plants) occurred in the heath forest at Pejem showed the highest abundance. Epiphytic fern plants, the Asplenium nidus (27 individual plants), was the dominant epiphytes found in the host tree of Dischidia The CCA showed that light intensity, temperature and humidity influenced the abundance of Dischidia.

Abstract

Anatomical structures may vary among the species of Nepenthes. Therefore, the anatomical characters apparently could be used for supporting the morphological characters in identifying species. This study aimed to seek a valuable anatomical character for identifying and defining five species of Nepenthes occur in Bangka Belitung Islands. Samples of leaves, pitchers and its lids of Nepenthes gracilis, Nepenthes mirabilis, Nepenthes ampullaria, Nepenthes rafflesiana, and Nepenthes reinwardtiana were collected and prepared for paradermal and transverse section of microscope slides. The results showed that the anatomical characters of the leaves, pitchers and lids from these five species of Nepenthes could be used for differentiating five species Nepenthes observed. The absence of nectary gland at the abaxial of pitcher lids of N. gracilis and N. ampullaria separate them from others species. The leaf epidermis of these two species have different cell wall. The length of lunate cells at the inner surface of upper half pitchers are comparable for identifying the pitchers of N. mirabilis from those of N. reinwardtiana.  The presence of crystal at the parenchymal tissue of pitcher differentiate N. rafflesiana from the four others.  In this research, the identification key for Nepenthes from Bangka Belitung Islands based on the anatomical character was presented.

Abstract

Aiming to collate the distribution and the attachment preference of intertidal bryozoan of Andaman waters, a study was carried out in three intertidal sites (Burmanallah, Kodiyaghat, and Chidiytapu) of southeastern coasts of the Andaman Islands between June and August 2016. The present study is the first exclusive report on bryozoans from the Andaman Islands after a long research gap of nine decades. During our investigation, a total of twelve genera were identified from both calcareous and non-calcareous substratum. Out of the twelve genera, eight genera were new records from the island. The present study showed that the attachment affinity of the Bryozoans is more towards natural substratum particularly on the rocks. The Thalamoporella sp. reported the most abundant species with maximum average colony length of 3.5 cm from the rock substratum.

Abstract

Toxoplasma gondii is an obligate intracellular protozoon, spread world-wide and capable of infecting birds and mammals. Genetic information on T. gondii type that causes human toxoplasmosis is limited. In this study, genetic analysis of SAG2 locus was used to determine the genotype of T. gondii from cases with cerebral and ocular toxoplasmosis in Indonesia. Genotype determination was done directly on the clinical samples. A number of 28 cerebrospinal fluid and 8 vitreous humor positively infected with T. gondii, underwent PCR-RFLP to classify each isolate into one of three genotypes of T. gondii. Type I was the most common found suggesting that cerebral and ocular toxoplasmosis in Indonesia is mostly caused by type I strain of T. gondii.

Abstract

Lupus nephritis (LN) is one of the manifestations of Systemic Lupus Erythematosus (SLE), with proteinuria being one of the clinical manifestations. The proteinuria pathogenesis is associated with anti-dsDNA antibody and the location of immune complex deposits within the kidney. This study aims to investigate the correlation of the severity of proteinuria with the location of immune complex deposits and the level of anti-dsDNA antibody in LN. Data were collected in cross-section. Fifty-three patients with LN in Saiful Anwar Hospital Malang, who underwent renal biopsy, were included. Hematoxylin-eosin staining and immunofluorescence analysis were used to assign subjects to different histopathological classes and determine the immune complex deposits. The spot urine samples were evaluated using the dipstick method for semi-quantitative proteinuria. The anti-dsDNA antibody levels were evaluated using the enzyme-linked immunosorbent assay (ELISA). Turbidity and enzymatic tests were conducted to elucidate urine protein and creatinine content, respectively. The level of proteinuria is significantly different among the different locations of immune complex based on the dipstick and protein/creatinine methods (p = 0.021 and p = 0.005, respectively). There was a significant correlation between anti-dsDNA antibody level and the severity of proteinuria (r = 0.326 based on dipstick and r = 0.28 based on protein/creatinine method). Thus, proteinuria in LN is determined by anti-dsDNA level and the location of immune complex deposits in the kidney.

Abstract

The study of exotic epiphytes on tree ferns is relatively scarce. Biological invasion of exotic epiphytes may imply negative consequences to native epiphytes and tree ferns, which are important components in tropical mountainous rainforest ecosystems. This study surveyed exotic epiphytes on tree ferns in Cibodas Botanical Gardens (CBG) and adjacent forests next to CBG. The objectives of this study are: a) to conduct inventory study of exotic epiphyte species on tree ferns, b) to examine how different these exotic epiphytes from each other based on their micro-climate preferences, c) to conduct invasive risk assessment of those exotic epiphytes, and d) to model the effect of environmental factors and host (tree ferns) characteristics to the occurrence of exotic epiphytes on tree ferns. We conducted multi-dimensional analysis to examine how different these exotic epiphytes based on their micro-climate parameters. We used Weed Risk Assessment (WRA) framework to estimate the invasion risks of surveyed exotic epiphytes. We performed Bayesian logistic regression to test the correlation between environmental and host characteristics and the occurrence probability of exotics epiphytes on tree ferns. We found 13 exotic epiphyte species on two native tree ferns species (Cyathea junghuhniana and Cyathea contaminans). Multidimensional analysis showed that Axonopus compressus is very different from other exotic epiphytes due to its environmental preferences. Ageratina riparia and Clidemia hirta were exotic epiphytes with the highest invasion risks. Therefore, we suggested that A. riparia and C. hirta are more likely to become invasive and may contribute significant impacts to native ecosystems. Lastly, the presence of Austroeupatorium inulaefolium as exotic epiphytes in tree ferns negatively correlated with the host height. Further study is needed to incorporate biological traits of the exotic epiphytes and more specific environmental parameters such as light chromatic quality in to the exotic epiphyte occurrence model. This study provides evidence for the existences of exotic epiphytes on tree ferns. The result of this study may also indicate that host characteristics and micro-climate factors could play important roles to inhibit the occurrence of exotic epiphytes on tree ferns.

Abstract

The ability of animal to perform self-medication has been studied decades, as well as their relationship with medication practices by communities. Long-term observation of Orangutans' behaviour (Pongo pygmaeus wurmbii), by communities surround Sebangau National Park, has suggested as their modes to today ethno-medication practice. The study was aimed to study the relationship of Orangutans self-medicate behavior with ethno-medication practice, in Sebangau area. The research was conducted in Punggualas, SNP, from 29 April to 03 October 2017. A number of 13 traditional healers (TH) from Karuing (n = 4), Baun Bango (n = 4), and Jahanjang (n = 5) have been interviewed. All plants are listed and photograph. Plants parts, and their mechanism of utilization were also kept for record. Meanwhile, the behavior followed the Orangutan protocol, with focus on their feeding behavior. All data were analyzed descriptively, while the relationship was analyzed using chi-square and F test. We have recorded a total 131 plants at various life forms, in Baun Bango (n = 59), Jahanjang (n = 41), and Karuing (n = 21). Plants that were found similar among three villages, removed, were only 95 left. We observed one female, showing the ability to perform self-mediaction. It is characterized by selectively choosing young leaves of Mezzetia sp., pulp of the Dyera lowii and Ilex cymosa, and lastly chew the entire leaves of Belang Handipek. It suggests a form of prevention against fatigue conditions, and the combination of these three plants species assume to be relating to fitness. This study shows that there is a relationship between the plant part used by the traditional healer and the orang- utan (x2 = 43,887; n = 115, df = 11, p-value = 0.0000), the relationship between the use of plant parts utilized by the traditional healer and orangutans (x2 = 15, 647; n = 50, df = 8, p-value = 0.0000). Furthermore, there is a relationship between the practice of traditional healer treatment using plant parts and Orang-utan (F1, 113 = 230.158; p-value = 0,000). The study urges to isolate secondary metabolites for further investigation, especially in terms of phyto-pharmacy.

Abstract

Riparians are undergoing extensive reductions and changes in their natural composition into agricultural and urban area. The relationship between the vegetation distribution pattern and the riparian topography factor has been assumed to typically represent a biome-specific or vegetation-specific constant. This study aim is to analyze the vegetation distribution pattern with topography along Alista river in Dau District, Malang. We surveyed 3 stations that represent a zone of edge gradient between the river and the mainland: levee, mid-flood, and slough. We used the wetland classification (Obligate - OBL; Facultative Wetland-FACW; Facultative Upland (FACU); and Upland (UPL) for each species found from various sources. we observed that facultative upland plants have a broad dominance. Mid-floodplain and slough dominated by typical upland species. Although Levee widely consisted of by upland plants, this area has one distinctive obligate species: Equisetum. The presence of OBL species in the levee and mid-floodplain indicate the area is receiving more frequent floods than other areas.
