Authors: Komala P S , Primasari B , Ayunin Q 
Published: September 2020

Abstract
The study was conducted in order to examine the relationship between the physicochemical parameters (temperature, DO and pH) with the orthophosphate (OP) and total phosphate (TP) concentrations based on the depth of Maninjau Lake. Samples were taken at the center of the lake near to a domestic area, endemic fisheries and a hydropower site. The OP concentration ranged from 0.182 - 0.570 mg/L and the TP of 0.265 - 0.603 mg/L indicated that Maninjau Lake was hypertrophic. This does not meet the quality standards regulated by the Indonesian Government. The physicochemical parameters of temperature, pH, and DO have a strong negative correlation with OP and TP concentrations with a correlation value of 0.828-0.982. ANOVA showed that depth stratification affects the OP and TP concentrations while the variation of sampling time does not affect the concentrations. The highest total phosphate concentration value was at the aquaculture cage location which exceeded the second class quality standard based on Government Regulation No. 82 of 2001. It shows that the aquaculture activities result in excess phosphate loads that can trigger lake eutrophication.

Published: September 2020

Abstract
Scour or landslide is a problem that occurs at river bends. Many methods are used for scouring or landslide protection. One of the protections for scouring construction is crib model by using gabions and current-aligning bamboo. The purpose of this study is to determine of the effect of variations in the placement of the crib by using of gabions model and the current-aligning bamboo on the river bends. This research is an experimental test of the hydraulic model using river flume model with 5m on bend length, 0.8m width, 0.5m height and a constant discharge of 7.07lt/sec. The test consists of testing control, that is a bend without reinforcement and testing with reinforcement at the bends. The reinforcement at the bends using placement variation was twice carried out with the variation 1 consisted of 3 current-aligning bamboo, 4 gabions, 3 current-aligning bamboo and the variation 2 contains the opposite. The test results showed that the maximum scouring occurs in variation 1 with -5.4cm, -5.2cm on landslides and 0.61cm on scour. The results of the Surfer App and cross sections of stations P00 until P07 are more effective using gabions, while P08 through P24 are more effective using current-aligning bamboo.

Published: September 2020

Abstract
Beneficial impacts on wellbeing levels of communities living near Protected Areas (PAs) is a key factor for meeting biodiversity conservation targets. Recent studies suggest that the proximity of communities to a PA influence to a significant extent their wellbeing levels. This paper explores further this argument by analysing data from approximately 800 respondents living inside or near four PAs of international importance in Greece. A Bayesian regression modelling approach testing which factors influence subjective wellbeing was applied. While wellbeing is explained by a combination of factors, the results of the study reveal that it is mainly PAs’ social impacts that have an effect on subjective wellbeing levels followed by the geographical location. This finding suggests that more effort needs to be invested in the equal distribution of PAs benefits in order to increase wellbeing and public support for these areas.

Abstract
Nipah worm (Namalycastis rhodochorde) belongs to the Polychaeta group that lived in the Nypa fruticans mangrove sediment in West Kalimantan. It has the potential to be cultivated because it has a high economic value in aquaculture. Feed aspect is an essential part of its cultivation, through improving the quality of feed by using probiotics isolated from its natural habitat, such as actinomycetes. These bacteria are known capable of producing secondary and primary metabolites. These metabolites are expected to increase immunity and biomass of worms. The purpose of this study was to isolate and determine the composition and characteristics of actinomycetes derived from mangrove sediment, gastrointestinal and faecal pellets of nipah worm that are potential as probiotic for feed formulation. Isolation and characterization of actinomycetes was conducted by pour plate method on SCA, ISP2, ISP3, ISP4, and ISP5 media; while characterization was by determining morphological characteristics of colonies, cell structure, and biochemical tests. Identification of the isolates referred to Bergey’s Manual of Determinative Bacteriology. The results showed that twelve isolates of actinomycetes had been found. Six isolates were from mangrove substrate, four isolates from fecal pellets and two isolates from the gastrointestinal tracts. All isolates were closely related to the genus Streptomyces.

Published: September 2020

AbstractThe heavy metals from an aquatic environment can be absorbed, transported, and stored in mangrove tissues. This study aims to assess accumulations of Cu and Zn in the sediment, root, and stem ofAvicenniasp. as affected by human activity in Blanakan riparian, West Java.Avicenniasp. root, stem, water, and sediment samples were collected from 2 stations located in Blanakan riparian. The concentrations of Cu and Zn in samples were measured using an atomic absorption spectrophotometer (AAS). Bioconcentration factor (BCF) and translocation factor (TF) equations were used to analyse the Cu and Zn accumulations inAvicenniasp. Based on the sediment quality guidelines, the sediment samples were not polluted for Cu (2.23–2.26 mg/kg) and moderately polluted for Zn (92.83–95.86 mg/kg). Moreover, the Cu and Zn in the water have BCF values of root ranging from 257.5–295 and 97.07–390.29, while BCF values of stem ranging between 590–990 and 90.23–330.21, respectively. Furthermore, the Cu and Zn in the sediment have BCF values of root ranging from 0.23–0.26 and 0.30–0.57, while BCF values of stem ranging between 0.53–0.88 and 0.30–0.48, respectively. In addition, the TF values ranged from 2.29–3.36 for Cu and 0.85–0.93 for Zn. To summarize, the root and stem ofAvicenniasp. have the ability to translocate Cu from water and sediment in Blanakan riparian.

Published: September 2020

Abstract
The rapidity of the batik industry in the Former Residence of Banyumas raises problems. Wastewater that discharged into upstream causes accumulation in downstream up to empties into the sea, so does not only threatens the river ecosystem but also has the potential to cause problems in the mangrove ecosystem in Segara Anakan (the downstream area of the Citanduy River which is very close to the downstream area of the Serayu River Basin). The strategy of batik wastewater management in an effort not to pollute the environment is offered. This study tried indigosol blue batik dye which are often used in the batik industry by using immobilization of the pure fungi biomass compared to biomass which was induced with tannic acid. Combination between incubation time and shaking treatment in immobilization of pure Aspergillus sp. biomass that capable to decolorize indigosol blue batik dye were also done. Data of degradation percentage was analyzed using spectrophotometry. The decolorization result of comparison between biomass of Aspergillus sp. with or without the addition of tannic acid under agitated treatment conditions at 24, 48, 72 hours were 54.7, 75.8, 77.4% and 78.8, 84, 80.1%, respectively. While the result of treatment under static conditions were 65.4, 86.3, 73.7% and 79.2, 78.6, 68.2, respectively. The next experiment is showed that 48th hour on static treatment have the highest decolorization percentage up to 67.1%. The pH was measured before and after treatment. The pH after treatment were decrease both in static and shaking treatment, and also in control treatment both in static and saker treatment. Based on the results of the research, the fact is the use of immobilization biomass of Aspergillus sp. in the form of alginate beads can be used for decolorization application in the environment.

Authors: Nabila G , Takarina N D 
Published: September 2020

Abstract
This study aims to determine the quality of water by evaluating the presence or absence of coliform bacteria and heavy metal Cu as well. The water quality evaluation was conducted in the upstream of Blanakan river, considering that the upstream is vulnerable since it receives more pollutants due to human activity. The water samples were collected from three stations in upstream. The Cu in water was analyzed using Atomic Absorption Spectroscopy (AAS). Likewise, the coliform bacteria were counted by using Most probably Number (MPN) method. The results showed that the range of coliform bacteria was 0.43 – 110 MPN/ml and the average was 36.9 MPN/ml, which is exceeding the range of water quality standard class I according to Government Regulation No.82 of 2001. Meanwhile, the average value of heavy metals Cu is 0.04 mg/L, which is also exceeding the range of water quality standard class I according to Government Regulation No.82 of 2001. Hence, the upstream of Blanakan river has been contaminated by coliform and Cu.

Published: September 2020

Abstract
Cilacap has a high potential for marine fisheries. However, no scientific data is available on the potential of marine ornamental fish from that area. Here we reported the preliminary study of the potential of marine ornamental fish from the southern coast of Cilacap with particular emphasis on species richness. A survey method with incidental sampling was conducted. Fish samples bought from the fish collector in Sentolo Kawat Village, District of South Cilacap, at Cilacap City. The fish samples were collected in April, May, and July 2019. Taxonomic identification of the fish samples was referring to the available reference and validated to the data in FishBase. Identification based on color pattern and meristic characters by considering geographic ranges of the specimen placed the samples into 28 species, 12 families, and four orders. Chaetodontidae was the most abundant family with nine species. Most fish belonged to Perciformes. We obtained a lower number of species compared to the previous study for the south coast of Java. It could be due to the narrower sampling areas and limited sampling periods. Nevertheless, our result provides information about the potential of marine ornamental fish in Cilacap as among promising income sources for the Cilacap Regency. However, government intervention is necessary for the sustainable use of ornamental fish in the area.

Published: September 2020

Abstract
Coliform bacteria are microorganisms that are often used as indicators of the presence of other pathogenic bacteria. Calculation of total coliform bacteria needs to be done to determine the presence of organic waste pollution that occurs in the Blanakan River Estuary, Subang, West Java. The purpose of this study was to determine the total abundance of coliform bacteria (water status based on coliform level) and to study the relationship between total coliform bacteria and Zn heavy metal content in the Blanakan River Estuary. The method used was purposive sampling carried out at three sampling stations. The results obtained showed that the average coliform content in the three stations ranged from 9.2 x 10−2 to 3.0 x 10−1 (0.092 – 0.3) MPN/ml sample. Zn heavy metal content in the water at three stations ranged from 0.61 mg/l to 2.13 mg/l. The conclusion of this study is the abundance of the average total Coliform bacteria obtained at each station shows that the total content of Coliform bacteria has not exceeded water quality standards according to the Government Regulation no 82 of 2001. The presence of total coliform bacteria has a weak relationship with the presence of metals Zn.

Published: September 2020

Abstract
Abstract Bayhops (Ipomoea pes-caprae (L.) R. Br.) is a kind of creeping herb growing in the coastal areas which can produce specific metabolites that are beneficial to humans. A study on the chlorophyll contents of this plant is important to find alternative sources of chlorophyll for health food supplements. This study aims to determine the chlorophyll contents of the bayhops in the coastal areas of Cilacap, i.e. Kamulyan, Bunton, and Sodong. The research method was experimental arranged in a completely randomized design of 6 treatments with three replications. The treatments used consisted of sea sand and soils from Kamulyan, Bunton, and Sodong. The parameters measured were the contents of chlorophyll a, chlorophyll b and total chlorophyll. The determination of chlorophyll contents was performed with acetone solvent, which was then measured by using a spectrophotometer. The results showed that growing habitat influences the chlorophyll contents. The bayhops found on further inland of Sodong contained the highest chlorophyll a, chlorophyll b and total chlorophyll.
Social Distancing to Mitigate COVID-19 Risks Is Associated With COVID-19 Discriminatory Attitudes Among People Living with HIV

Published: September 2020

AbstractBackgroundSevere acute respiratory syndrome coronavirus-2, the virus that causes COVID-19, is an emerging pandemic with heightened concerns for people with compromised immune systems, including people living with HIV.PurposeIn the absence of a vaccine, public health messaging to mitigate risks for COVID-19 primarily focuses on social distancing. Because people living with HIV commonly experience mistreatment associated with HIV, their response to social distancing may be complicated by psychosocial attitudes associated with COVID-19.MethodsTo evaluate these relationships, we conducted a rapid-response, cross-sectional survey with people living with HIV (N = 149) to assess social distancing practices, COVID-19 discriminatory attitudes, COVID-19 xenophobic attitudes, HIV microaggressions, and concern over contracting COVID-19. Data were collected from participants enrolled in a larger ongoing study between March 30, 2020 and April 17, 2020.ResultsResults indicated that choosing to socially distance to reduce COVID-19 exposure was associated with COVID-19 discriminatory attitudes, concerns of contracting COVID-19, and identifying as transgender. Likewise, social distancing imposed by others (e.g., cancelations and restrictions) was associated with concerns of contracting COVID-19.ConclusionsFindings demonstrate that social distancing measures are related to concerns of contracting the virus and discriminatory attitudes toward those who are presumed to be living with COVID-19. These potentially negative psychosocial attitudes toward people perceived to have COVID-19 echo the discriminatory actions and attitudes that we continue to observe in HIV social sciences research.
Interventions to ameliorate reductions in muscle quantity and function in hospitalised older adults: a systematic review towards acute sarcopenia treatment
Authors: Welch Carly , Majid Zeinab , Greig Carolyn , Gladman John , Masud Tahir , Jackson Thomas 
Published: September 2020

Abstract

Objective
Assimilate evidence for interventions to ameliorate negative changes in physical performance, muscle strength and muscle quantity in hospitalised older adults.

Methods
We searched for articles using MEDLINE, Embase, CINAHL and Cochrane library using terms for randomised controlled trials, older adults, hospitalisation and change in muscle quantity, strength or physical performance. Two independent reviewers extracted data and assessed risk of bias. We calculated standardised mean differences for changes in muscle function/quantity pre- and post-intervention.

Results
We identified 9,805 articles; 9,614 were excluded on title/abstract; 147 full texts were excluded. We included 44 studies including 4,522 participants; mean age 79.1. Twenty-seven studies (n = 3,417) involved physical activity interventions; a variety were trialled. Eleven studies involved nutritional interventions (n = 676). One trial involved testosterone (n = 39), two involved Growth Hormone (n = 53), one involved nandrolone (n = 29), and another involved erythropoietin (n = 141). Three studies (n = 206) tested Neuromuscular Electrical Stimulation. Evidence for effectiveness/efficacy was limited. Strongest evidence was for multi-component physical activity interventions. However, all studies exhibited at least some concerns for overall risk of bias, and considering inconsistencies of effect sizes across studies, certainty around true effect sizes is limited.

Conclusion
There is currently insufficient evidence for effective interventions to ameliorate changes in muscle function/quantity in hospitalised older adults. Multiple interventions have been safely trialled in heterogeneous populations across different settings. Treatment may need to be stratified to individual need. Larger scale studies testing combinations of interventions are warranted. Research aimed at understanding pathophysiology of acute sarcopenia will enable careful risk stratification and targeted interventions.

Abstract
Metabarcoding of prey DNA from fecal samples can be used to design behavioral experiments to study the foraging behavior and sensory ecology of predators. The frog-eating bat, Trachops cirrhosus, eavesdrops on the mating calls of its anuran prey. We captured wild T. cirrhosus and identified prey remains in the bats’ fecal samples using DNA metabarcoding of two gene regions (CO1 and 16S). Bats were preying on frogs previously unknown in their diet, such as species in the genus Pristimantis, which occurred in 29% of T. cirrhosus samples. Twenty-three percent of samples also contained DNA of Anolis lizards. We additionally report apparently rare predation events on hummingbirds and heterospecific bats. We used results from metabarcoding to design acoustic and 3D model stimuli to present to bats in behavioral experiments. We show predatory responses by T. cirrhosus to the calls of the frog Pristimantis taeniatus and to the rustling sounds of anoles moving through leaf-litter, as well as attacks on a stuffed hummingbird and a plastic anole model. The combination of species-specific dietary information from metabarcoding analyses with behavioral responses to prey cues provides a unique window into the foraging ecology of predators that are difficult to observe in the wild.
