Published: June 2019

AbstractThe purpose of this study was to observe the phytoremediation process for removal of Pb(II) from aqueous solution usingEchinodorus palaefolius(Jasmine water). The process was determined by the root, stem and leaves ability to reduce the Pb(II). The experiment was done in three factors, as a function of weight of plant (2–10 g/100 mL), initial concentration of Pb(II) (10–30 mg/l) and contact time (30–120 minutes) into the final concentration of Pb(II) removal as the response. The effect of three factors in Pb(II) phytoremediation was explained using response surface methodology (RSM). The results revealed that the phytoremediation process can successfully remediate Pb(II) from aqueous solution with the Pb(II) adsorbed ranging between 0.231 mg/L – 2.431 mg/L. The highest phytoadsorption of Pb(II) usingEchinodorus palaeofoliusoccurred in roots. Optimizing the condition using 2FI model predicts weight of plant 2 gr, initial concentration of Pb(II) 30 mg/L and contact time 120 minutes. The initial concentration and contact time are significant factors influencing the phytoremediation process.

Abstract
Universitas Indonesia’s urban forest is a part of Universitas Indonesia’s campus area, which covered 192 hectares from total 320 hectares campus area. Universitas Indonesia as a green campus has many green open spaces that distributed throughout campus and consists of several tree species. The age of the most vegetation in both urban forest and green open space has been 30 years old. This condition required routine management to evaluate tree health and risk. Some routine management has been conducted which consist of pruning and eliminating dead trees followed by replanting of new trees. This management aims to reduce the risk posed by trees related to community safety and for keeping environmental sustainability. The method that we used to assess the tree risk were visual tree risk assessment (VTA) based on biological characteristics of the risked tree. The result showed that there are four major species that need more routine management and had a higher percentage of managed trees during 2018. Those species were Acacia mangium, Hevea brasiliensis, Enterolobium cyclocarpum, and Delonix regia.

Abstract
Kenjeran waters are one of the waters located in the eastern part of the city Surabaya which has been polluted by heavy metals. The presence of heavy metals in the waters, automatically affect bivalves that live in these waters which will accumulate the metal on the body. This research aim was to determine the Health Benefit Value of Selenium (HBV-Se) as a food safety index from mercury contamination in bivalves consumption and to recognize MeanWeekly Intake (MWI) bivalves consumption in Kenjeran waters. The concentration analysis for Selenium using ICP-OES and Total mercury (THg) using Mercury Analyzer NIC-MA3000. Mercury and Seleniumwere calculated to gain HBV-Se index. The mercury concentration result showedPerna viridis 0.09 mg/kg, Siliqua patula 0.07 mg/kg, Trisidos tortuosa 0.08 mg/kg, and Anadara antiquata 0.08 mg/kg. The selenium concentration in bivalves between 0.91 mg/kg-2.49 mg/kg. The concentration of mercury below the quality standard on the limit determined by SNI, about 1 mg/kg. Total mercury from highest concentration were Perna viridis>Anadara antiquata>Siliqua patula>Trisidos tortuosa. From the calculation HBV-Se result showed positive value, it means indicating mercury contained in bivalves at Kenjeran Waters were not potentially to be toxic on the body. For the safety purpose, maximum consumption on bivalves for an adult is Perna viridis 8.64 kg/week, Siliqua patula6.62 kg/week, Trisidos tortuosa 3.91 kg/week and Anadara antiquata 4.49 kg/week. For the same reason, the maximum consumption for children Perna viridis 1.44 kg/week, Siliqua patula 1.10 kg/week, Anadara antiquata 0.65 kg/week, Trisidos tortuosa 0.75 kg/week

Abstract
The radiopharmaceutical kit production facilities usually use a clean room with an aseptic process. Therefore, it is very important to conduct research on clean room utilization for the production of radiopharmaceutical kits. The data was taken from radiopharmaceutical product that produced at Center for Radioisotope and Radiopharmaceutical Technology (PTRR), National Nuclear Energy Agency (BATAN) from 2015 to 2018. The results indicate the use of clean room depends on the drying duration of the radiopharmaceutical kit. Almost all radiopharmaceutical kits are dried for two days such as MIBI, MDP, Ethambutol, MAA, and Tetrofosmin kits. There are only two kits that are dried for one day, DTPA and EDTMP kits. The ratio of monitoring of drying temperatures during the drying process of DTPA kit (one day) and MDP kit (two days) shows that in 2015 the freeze dryer still showed maximum performance compared to the next three years. The optimal utilization of clean room is in 2015 as much as 100% while in 2016, 2017 and 2018 the average utilization of clean room is around 66%. The production process frequency is the lowest in June, followed by January and December due to the maintenance schedule. The longer the process of drying radiopharmaceutical kits, the longer the clean room facilities operate. The production process of radiopharmaceutical kits in 2015 is the most optimal.

Published: June 2019

Abstract
Lobster fisheries play a very important role in the development of Indonesian fisheries management. Lobster fishing for Indonesian people plays a role in the economic, social and political fields. The key reason for this important role is because lobster fisheries are dominated by small-scale fishermen. Lobster also has ecological functions that play a key role in a benthic aquatic ecosystem. Tropical lobsters in the Panulirus group in Indonesian waters (Eastern Indian Ocean) are the most species and have high endemic levels. It is reasonable if the Indonesian government makes lobster fisheries as one of the fisheries groups that need to be considered in its territorial fisheries management (FMARI: Fisheries Management Area of the Republic of Indonesia). Each management area has different ecological characteristics. Differences in ecological conditions will cause differences in the composition of lobster species. For the sake of lobster fisheries management in each region, it is necessary to specify indicator species on the spatial and temporal scale. This study aims to identify lobster species of the genus Panulirus in the FMARI 573 eastern part of Indonesian waters. Data retrieval is done by taking samples from lobster fishermen. Sampling locations include Kebumen, Trenggalek, Blitar, Lumajang, Jember, and Sumenep. The sampling time was carried out in August-September 2018. Data was analyzed descriptively by identifying morphologically and recording the number of individuals per species. Identification of samples is carried out at the study site and also in the laboratory. The study found six lobster species, namely: Panulirus ornatus (Udang mutiara), P. homarus (U. pasir), P. penicillatus (U. batu), P. versicolor (U. bambu), P. longipes (U. batik) and P. polyphagus (U. pakistan) with the type of sand most often found among the study sites. Further research needs to be done to look at the distribution and connectivity of lobster populations by analyzing species variation in each life phase (larvae / puerullus, juvenile, adult) at a certain space and time scale.

Abstract
The high number of tourists visit to Malang shows that Malang is still one of the favourite tourist destinations. Two of them are Kampung Wisata Jodipan and Kampung Biru. The existence of tourism-based villages provides economic, socio-cultural, and ecological impacts. Development and environment have interrelated, reciprocal, and very close interactions. This research was ex post facto which aimed to determine the correlation of environmental concern and age, and also to compare the environmental concern in two tourism villages in Malang City. The sampling was conducted using random sampling. Data collection was carried out by observation, interview, and questionnaires about environmental concern questionnaires to residents in both tourism villages. Data were analyzed by descriptive analysis and Pearson correlation. The results showed that the age and concern of the community in Kampung Wisata Jodipan did not correlate, with p = 0.926 > α = 0.05, which means there was no relationship between the age of the community and environmental concern. In Kampung Biru, age also does not correlate with community concern with p = 0.181 > α = 0.05, which means there is no relationship between the age of the community and environmental concerns.

Abstract
Gambier (Uncaria gambir Roxb) is one of the sources of natural dyes that able to apply to the textile industry. Textile dyeing industrial wastewater using Gambier comes from several sources. Among them come from the dyeing process itself and from the fixation process wastewater using alum (Al2 (SO4)3), lime (CaO) and tunjung (FeSO4). The wastewater was characterized by high levels of organic pollutants and dyestuffs as well as compositions of fixator raw materials. This study explored the performance of two types of Multi-Soil-Layering (MSL) bioreactors in order to reduce pollutant parameters in such a wastewater. The result revealed that MSL showed good performances. The more MSL layers, the higher the reduction. Reduction of BOD5, COD, and TSS in MSL type 1 could reach 98.6%, 95.3% and 87.1% respectively, while 98.1%, 93.8% and 84.9% in MSL type 2, respectively. The MSL bioreactor could neutralize pH from pH 4.7 to be pH 7.4 and pH 7.1 and able to reduced colour from 427 PtCo to 0.4 PtCo and 1.3 PtCo as well as reduced turbidity from 47 NTU to 0.8 NTU and 1.2 NTU by MSL type 1 and MSL type 2 respectively.

Published: June 2019

Abstract
Abnormal pore pressure can cause some problems during the drilling process such as a blowout or sticking pipe while drilling. Pore pressure prediction may prevent the drilling hazard, especially in carbonate field that known as a complex reservoir. It is useful for mud weight determination to prevent blowout and sticking pipe while drilling. This study focuses on predicting pore pressure values and maps it through 3D seismic data. The field is carbonate reservoir which known as a heterogeneous formation with shale above the reservoir. Due to the difference of lithologies, the two different empirical parameter is used in each lithology for Eaton equation. The pore pressure prediction then correlates with the seismic attribute using a neural network method. The input parameter of the Eaton is sonic and density log. Then, the result of Eaton’s method is calibrated by leak-off test (LOT) and repeat formation test (RFT), hence the results are more accurate and verified. Then, the pore pressure is correlated to acoustic impedance, shear impedance, seismic frequency, and seismic amplitude to create a subsurface model by the neural network machine learning. The result shows that the pore pressure prediction of the model is verified by the measured pore pressure well-log data with good accuracy up to 90%. The combination method of Eaton and neural network was proven to be able to predict and map pore pressure distribution in a complex carbonate field.

AbstractHousehold surveys remain an essential method for estimating vaccine coverage in developing countries. However, the resulting estimates have inevitable and currently unmeasurable information biases due to inaccuracies in recall, low retention of home-based records (HBRs; i.e., vaccination cards), and inaccurate recording of vaccination on HBRs. We developed an innovative method with which to overcome these biases, enhance the validity of survey results, and estimate true vaccine coverage using nested serological assessments of immune markers. We enrolled children aged 12–23 months in vaccine coverage surveys in Karachi, Pakistan, from January to December 2016. Vaccination history was collected through verbal recall by the caregiver and, when available, by HBR. One-third of survey participants were randomly enrolled for serological testing for anti–measles virus immunoglobulin G antibody. We applied Bayesian latent class models to evaluate the misalignment among measles vaccination histories derived by recall, HBRs, and measles serology and estimated true measles vaccine coverage. The model-based estimate of true measles vaccine coverage was 61.1% (95% credible interval: 53.5, 69.4) among all survey participants. The standard estimate of 73.2% (95% confidence interval: 71.3, 75.1) defined by positive recall or HBR documentation substantially overestimated the vaccine coverage. Researchers can correct for information biases using serological assessments in a subsample of survey participants and latent class analytical approaches.

AbstractBackground and AimsWe have recently shown that an Arabidopsis thaliana double mutant of type III phosphatidylinositol-4-kinases (PI4Ks), pi4kβ1β2, constitutively accumulated a high level of salicylic acid (SA). By crossing this pi4kβ1β2 double mutant with mutants impaired in SA synthesis (such as sid2 impaired in isochorismate synthase) or transduction, we demonstrated that the high SA level was responsible for the dwarfism phenotype of the double mutant. Here we aimed to distinguish between the SA-dependent and SA-independent effects triggered by the deficiency in PI4Kβ1 and PI4Kβ2.MethodsTo achieve this we used the sid2pi4kβ1β2 triple mutant. High-throughput analyses of phytohormones were performed on this mutant together with pi4kβ1β2 and sid2 mutants and wild-type plants. Responses to pathogens, namely Hyaloperonospora arabidopsidis, Pseudomonas syringae and Botrytis cinerea, and also to the non-host fungus Blumeria graminis, were also determined. Callose accumulation was monitored in response to flagellin.Key ResultsWe show here the prominent role of high SA levels in influencing the concentration of many other tested phytohormones, including abscisic acid and its derivatives, the aspartate-conjugated form of indole-3-acetic acid and some cytokinins such as cis-zeatin. We show that the increased resistance of pi4kβ1β2 plants to the host pathogens H. arabidopsidis, P. syringae pv. tomato DC3000 and Bothrytis cinerea is dependent on accumulation of high SA levels. In contrast, accumulation of callose in pi4kβ1β2 after flagellin treatment was independent of SA. Concerning the response to Blumeria graminis, both callose accumulation and fungal penetration were enhanced in the pi4kβ1β2 double mutant compared to wild-type plants. Both of these processes occurred in an SA-independent manner.ConclusionsOur data extensively illustrate the influence of SA on other phytohormone levels. The sid2pi4kβ1β2 triple mutant revealed the role of PI4Kβ1/β2 per se, thus showing the importance of these enzymes in plant defence responses.
A Biohistorical Perspective of Typhoid and Antimicrobial Resistance
Authors: Kirchhelle Claas , Dyson Zoe Anne , Dougan Gordon 
Published: June 2019

AbstractWe combine methodology from history and genetics to reconstruct the biosocial history of antimicrobial resistance (AMR) in the bacterium Salmonella enterica serovar Typhi (S. Typhi). We show how evolutionary divergence in S. Typhi was driven by rising global antibiotic use and by the neglect of typhoid outside of high-income countries. Although high-income countries pioneered 1960s precautionary antibiotic regulations to prevent selection for multidrug resistance, new antibiotic classes, typhoid’s cultural status as a supposedly ancient disease of “undeveloped” countries, limited international funding, and narrow biosecurity agendas helped fragment effective global collective action for typhoid control. Antibiotic-intensive compensation for weak water and healthcare systems subsequently fueled AMR selection in low- and middle-income countries but often remained invisible due to lacking surveillance capabilities. The recent rise of extensively drug-resistant typhoid bears the biosocial footprint of more than half a century of antibiotic-intensive international neglect.

Abstract

Background
Respiratory syncytial virus (RSV) causes substantial morbidity and mortality among children worldwide, commonly through acute lower respiratory tract infections (ALRI). To assess the incidence rate of symptomatic RSV illness among young children, we conducted a prospective birth cohort study following children from 0–2 years of age in Managua, Nicaragua.

Methods
Children meeting the testing criteria (fever, history of fever, or severe respiratory symptoms [apnea, stridor, nasal flaring, wheezing, chest indrawing, and/or central cyanosis]) were tested for RSV infections using real-time reverse transcriptase-polymerase chain reaction. An acute lower respiratory infection was defined as a diagnosis of pneumonia, bronchiolitis, bronchitis, or bronchial hyperreactivity. The incidence rate was calculated, and 95% confidence intervals were estimated using a Poisson distribution.

Results
A total of 833 children participated in the cohort: 289 (34.7%) had at least 1 episode of laboratory-confirmed RSV, and 156 (18.7%) of had an episode of RSV-associated ALRI (RSV-ALRI). The incidence rate of symptomatic RSV was 248.1 cases per 1000 person-years (95% confidence interval [CI] 223.2–275.7). While infants aged 6–11 months had the highest incidence of symptomatic RSV (361.3/1000 person-years, 95% CI 304.4–428.8), infants &lt;3 months had the highest incidence of severe RSV (RSV-associated hospitalizations and/or severe ALRI). RSV was also associated with 25.0–37.5% of deaths from medical causes (n = 8).

Conclusions
A substantial burden of RSV exists among children aged &lt;2 years in Nicaraguan communities. RSV was also a leading cause of infant mortality among study participants. The development and implementation of effective RSV prevention and treatment measures represent an opportunity to substantially reduce severe illness and death among children worldwide.
Anwar Shaikh and the classical theory of interest: a critical note
Authors: Toporowski Jan 
Published: June 2019

AbstractThe Note examines the theory of interest put forward in Shaikh’s recent book Capitalism, Competition, Conflict, Crises which presents the classic Ricardian theory of interest, in which the rate of interest is determined by the industrial rate of profit, as the basis for the book’s analysis of banking and credit. The Note argues that the classic theory of Anwar Shaikh holds true only under special assumptions, namely when money is a produced commodity, and credit is external to the system of capitalist production. However, in the modern capitalist economy, credit is endogenous to the system of production and distribution. In this more general case, debt and interest have the function of redistributing income, but are unrelated to the rate of profit from production.
1979 and all that: a 40-year reassessment of Margaret Thatcher’s legacy on her own terms
Authors: Albertson Kevin , Stepney Paul 
Published: June 2019

AbstractEconomics are the method: The object is to change the soul (Thatcher, 1981)There is a growing disaffection with mainstream politics in the world’s liberal democracies. In particular, the UK has become an increasingly divided nation; as evidenced by, for example, increasing inequality, an emphasis on individualism, the so-called North/South divide and the polarised debate about the UK’s leaving the European Union. Many leading UK politicians claim their inheritance of the “Thatcher legacy” to legitimate their proposed policies, yet it is not clear what is that legacy. Thatcher’s policies, instituted in the 1980s and broadly pursued by subsequent governments, changed the economic and social outlook of the UK. Criticism of her record is taken to indicate one is a left-wing ideologue. Our contribution in the following is that we judge Thatcher’s policies by no standards other than her own. Utilising a holistic approach, we consider whether neo-liberal policies facilitated or undermined the UK’s achieving Thatcher’s stated moral outcomes: the growth of democratic capitalism and the strengthening of the moral economy. We demonstrate, in contrast to contemporary narratives of her “saving the country”, the neo-liberal economic experiment has failed to deliver, even on Thatcher’s own terms. This analysis has contemporary domestic and global implications as generally Thatcherite policies continue to be applied in the UK and in other nations around the world.
