Abstract
Propolis, a complex substance of resinous, is produced by honeybees. Propolis contains a number of flavonoid compounds endowed with antimicrobial and antioxidant capabilities. The main chemical constituents and physicochemical properties of propolis are depended on many factors including geographic origin. This study was undertaken to evaluate antibacterial, antibiofilm, and antioxidant activities of propolis collected from Kalimantan, Indonesia. The phytochemical properties of propolis were identified by total phenolic contents, total flavonoid contents, and FTIR analysis. Propolis was extracted using 96% ethanol, 70% ethanol, and n-hexane solvents. Moreover, the bioactivity capacity of propolis extracts were observed through antioxidant and antibacterial activities. The results showed that propolis extracts exhibited varying degrees of phenolic content, flavonoid contents, antibacterial, and antiradical scavenging properties. The highest value of total flavonoid content was obtained on 96% ethanol propolis extract as well as its remarkable antibacterial and antiradical scavenging activities.

AbstractDespite great improvements in childhood mortality in the past several decades, many Indonesian children did not surpass their fifth birthday. This paper investigates the social and environmental determinants of under-five (U-5) mortality in Indonesia. By utilising the most recent Indonesia Demographic and Health Survey (IDHS) in 2017, we fitted survival regression models to the data. We observed that maternal smoking (aHR = 2.15, 95% CI = 1.15–4.03), maternal age (aHR = 2.48, 95% CI = 1.43–4.30), and maternal employment status (aHR = 1.68, 95% CI = 1.34–2.11) correspond to shorter lives of U-5 children. Conversely, we found that higher maternal education (aHR = 0.50, 95% CI = 0.29–0.87) corresponds to better child survival. Improved household sanitation also negatively associated with child mortality, albeit statistically insignificant at 5% (aHR = 0.78, 95% CI = 0.60–1.01). These associations hold after we take into account proximate and biological correlates. These findings corroborate extant literature that living environment (not only socio-economic and demographic factors) plays a prominent role in determining child survival. Hence, increasing access to and reducing the rural-urban gap related to improved sanitation facilities and curtailing smoking prevalence are paramount in further curbing child mortality.

Abstract
This study identifies and quantifies floating macro litter and macro plastic from Deli River Medan during pandemic Covid-19. Macro litter transport consists of floating items at surface, suspended in water column and transport over on riverbed. Litter was collected from 5 location along 11.6 km using static trawls with a height of 150 cm and width of 300 cm with a square mesh size of 0.5 cm. Sampling was done in July, and during selection, 40 cm of net’s height was constantly submerged for one hour. This study found that macro litter was 19.26 kg/h with 65.2% as anthropogenic waste, 34.3% as macro plastic, 0.3% as metal, and 0.15% as medical waste. The composition of macro plastic has various variants, namely food containers, plastic bags, food packaging, sanitary packaging, and mineral water packaging with percentages of 10.21%, 67.89%, 8.35%, 4.36%, and 9.18%. The macro plastic abundance was obtained at 2,476 x 10-4 kg/m3. This study showed a significant increase in plastic consumption during the pandemic, especially plastic bags because it is dominated in all locations.

Published: July 2022

Abstract
The population of Surakarta has increased, putting pressure on vegetation and increasing demand for land availability. The population reached 500,173 people in 2010. The population trend is increasing every year so that the need for land as a place to live and living facilities also increases. This study aims to analyze the relationship between canopy density and the urban index in a 5 year period (2010 – 2015). The method used in assessing the density of the vegetation canopy is the calculation of the Normalized Difference Vegetation Index (NDVI) and the urban index. The calculation of the two index values uses Landsat 8 OLI satellite image data in 2015. The results show that the value of canopy density is inversely proportional to the value of urban index. The higher value of canopy density in Surakarta is followed by the lower value of urban index. The relationship between both is very close, marked by very high correlation and determination coefficient values, namely -0.98 and 0.97. Research on canopy density and urban index on a regular basis is expected to be part of the process of monitoring and evaluating urban area development and as input for local governments in the decision-making process.

Abstract
The aim of this research was to evaluate the effects of feeding fermented sago waste on production performance and nutrient digesbility of male kacang goats. The study employed a randomized block design, with 4 dietary treatments, i.e, of Field Grass (FG), Fermented Sago Waste (FSW) and Concentrate. The treatments were: T0 = 60% FG + 0% FSW + concentrate, T1 = 45% FG + 15% FSW + concentrate, T2 = 30% FG + 30% FSW + concentrate, and T3 = 15% FG + 45% FSW + concentrate. Each treatment consisted of three groups, so that the number of experimental units were 12 kacang goats which were grouped according to body weight between 18-23 kg. The results showed that dietary inclusion of FSW to substitute FG increased (P<0.05) feed intake, ADG, feed efficiency, dry matter digestibility (DMD) and organic matter digestibility (OMD) of kacang goats. However, the inclusion at T1 and T2 decreased (P<0.05) the R/C ratio in comparison to control group. The T3 treatment produced the highest ADG, DMD and OMD values. In conclusion, FSW is able to replace FG and therefore potential to be used as a forage source for ruminants in West Kalimantan.

Abstract
Silver is widely used in medical materials, photography, electronics and other industries as a precious metal. The large-scale industrial production of silver-containing products and liquid waste emissions aggravate the environmental pollution. Silver ion is one of the most toxic metal ions, causing pollution to the environment and damage to public health. Therefore, the efficient and sensitive detection of Ag+ in the water environment is extremely important. Sulfur-doped carbon nitride nanosheets (SCN Ns) were prepared by melamine and thiourea via high-temperature calcination. The morphology, chemical composition and surface functional groups of the SCN Ns were characterized by SEM, TEM, XRD, XPS, and FT-IR. The fluorescence of SCN Ns was gradually quenched as the Ag+ concentration increased. The detection limit for Ag+ was as low as 0.28 nM. The quenching mechanism mainly is attributed to static quenching. In this paper, SCN Ns were used as the fluorescent probe for detecting Ag+. SCN Ns have successfully detected Ag+ in different environmental aqueous samples and cells. Finally, SCN Ns were further applied to the visual quantitative detection of intracellular Ag+.

Published: July 2022

Abstract
Inkjet printing technique provides a low-cost way for large-area construction of the patterned organic semiconductors toward integrated organic electronics. However, because of a lack of control over the wetting and dewetting dynamics of organic inks, inkjet-printed organic semiconductor crystals (OSCCs) are frequently plagued by the ‘coffee ring’ effect and uncontrollable growth process, leading to an uneven crystal morphology and disordered orientation. Here, we report a universal microchannel-assisted inkjet printing (MA-IJP) method for patterning of OSCC arrays with ordered crystallographic orientation. The micro-sized channel template not only provides a unidirectional capillary force to guide the wetting process of organic inks, but also confines the evaporation-induced dewetting behavior, enabling the long-range ordered growth of OSCCs. The patterned 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT) crystals present one-dimensional structures with a pure (010) crystallographic orientation. The 7 × 7 discrete organic field-effect transistor array made from the patterned C8-BTBT crystals exhibits a high average mobility up to 3.23 cm2 V−1 s−1 with a maximum mobility of 5.36 cm2 V−1 s−1. Given the good generality of the patterning process and high quality of the obtained OSCC crystal array, it is anticipated that our MA-IJP approach will constitute a major step toward integrated electronic and optoelectronic devices.

Published: July 2022

Abstract
The urgent demand for energy structural reform and the limitations of single energy development have promoted the combination of wind energy and wave energy. A hybrid energy system means that two or more energy devices share the same foundation. It reduces the levelized cost of energy and improves competitiveness through infrastructure sharing and increased power output. This paper starts with the development of the joint resources of wind and wave energies, then introduces the foundation forms of the hybrid system. It reviews the latest concepts and devices proposed with the integration of wind energy and wave energy, according to the foundation forms, and makes a preliminary assessment of the synergies of the hybrid system. The existing study methods of the hybrid systems are summarized. In view of the challenges faced by the development of hybrid energy systems, several suggestions are put forward accordingly. This paper provides a comprehensive guideline for the future development of the hybrid wind-wave energy converter system.
Chemical and structural identification of material defects in superconducting quantum circuits
Authors: de Graaf S E , Un S , Shard A G , Lindström T 
Published: July 2022

AbstractQuantum circuits show unprecedented sensitivity to external fluctuations compared to their classical counterparts, and it can take as little as a single atomic defect somewhere in a mm-sized area to completely spoil device performance. For improved device coherence it is thus essential to find ways to reduce the number of defects, thereby lowering the hardware threshold for achieving fault-tolerant large-scale error-corrected quantum computing. Given the evasive nature of these defects, the materials science required to understand them is at present in uncharted territories, and new techniques must be developed to bridge existing capabilities from materials science with the needs identified by the superconducting quantum circuit community. In this paper, we give an overview of methods for characterising the chemical and structural properties of defects in materials relevant for superconducting quantum circuits. We cover recent developments from in-operation techniques, where quantum circuits are used as probes of the defects themselves, toin situanalysis techniques and well-establishedex situmaterials analysis techniques. The latter is now increasingly explored by the quantum circuits community to correlate specific material properties with qubit performance. We highlight specific techniques which, given further development, look especially promising and will contribute towards a future toolbox of material analysis techniques for quantum.

AbstractObjectivesExtended testing for high-risk human papillomavirus genotypes (hrHPVGTs) is increasingly investigated for risk stratification in cervical cancer screening.MethodsAge and hrHPVGT results from 16,993 women with atypical squamous cells of undetermined significance (ASC-US) cytology between November 2015 and August 2021 were studied and correlated with available histopathologic findings within 6 months.ResultsHigh-risk human papillomavirus (hrHPV)–positive rate was 66.9% in women with ASC-US cytology, and the most prevalent genotypes were HPV 52 (20.9%), 16 (15.7%), and 58 (12.8%). Single hrHPV genotypes and multiple HPV genotypes were detected in 77.2% and 22.8% of women with hrHPV-positive results. Cervical intraepithelial neoplasia grade 2 or more (CIN2+) severe lesions were identified in 19.5% of women with hrHPV-positive ASC-US. The greatest risk for CIN2+ was found in single genotype infections with HPV 16 (33.1%), followed by women with multiple genotype infections, including HPV 16 (32.7%), 82 (30.8%), and 31 (30.0%). hrHPVGT testing for genotypes 16, 31, 35, 45, 82, 58, 33, 52, and 18 was identified in 91.9% (965/1,050) of CIN2+ cases, with 88.9% sensitivity, 43.2% specificity, positive predictive value of 23.9%, and negative predictive value of 95.1%.ConclusionsExtended hrHPV genotyping for women with ASC-US cytology could identify those hrHPV genotypes (HPV 16, 31, 35, 45, 82, 58, 33, 52, 18) associated with higher risk of CIN2+ and allows for refined risk stratification of women being screened.

Published: July 2022

Abstract

Background
Masked hypertension is more common in individuals with type 2 diabetes than in individuals with normoglycemia. We aimed to explore if there is a discrepancy between office blood pressure (office BP) and home blood pressure monitoring (HBPM) in relation to HbA1c as well as glycemic status in 5,029 middle-aged individuals.

Methods
HBPM was measured in a subsample of 5,029 participants in The Swedish CardioPulmonary BioImage Study (SCAPIS), a population-based cohort of 50–64 years old participants. Both office BP and HBPM were obtained after 5 minutes’ rest using the semiautomatic Omron M10-IT oscillometric device. White coat effect was calculated by subtracting systolic HBPM from systolic office BP. Participants were classified according to glycemic status: Normoglycemia, prediabetes, or diabetes based on fasting glucose, HbA1c value, and self-reported diabetes diagnosis.

Results
Of the included 5,025 participants, 947 (18.8%) had sustained hypertension, 907 (18.0%) reported taking antihypertensive treatment, and 370 (7.4%) had diabetes mellitus. Both systolic office BP and HBPM increased according to worsened glycemic status (P for trend 0.002 and 0.002, respectively). Masked hypertension was more prevalent in participants with dysglycemia compared with normoglycemia (P = 0.036). The systolic white coat effect was reversely associated with HbA1c (P = 0.012).

Conclusions
The systolic white coat effect was reversely associated with HbA1c, and the prevalence of masked hypertension increased with dysglycemia.
