Abstract
Potassium and calcium are elements contained in seawater. The presence of potassium and calcium in raw saltwater were impurities in producing non-food salt. On the other hand, potassium and calcium as target minerals are desirable in mineral-rich healthy salt (food salt) production. Information about the potassium and calcium content in raw salt water can assist in analyzing the quality of the salt to be produced. The purposes of this study were; to determine the content of potassium, and calcium in Padelegan waters used as a source of salt raw materials, compare them with other locations, and their correlation with water quality. The potassium and calcium content in the sample were determine used the AAS (Atomic Absorption Spectrophotometry) method. Potassium concentrations ranged from 221,870 to 285,110 mg/L, and those for calcium from 497,700 to 552,713 mg/L. The potassium content in Padelegan waters is smallest than other reference waters. In contrast, the calcium content in Padelegan waters is greatest than in other reference waters.

Abstract
Mangroves have high primary productivity so they are known as good carbon storage and absorbers (carbon sequestrators). This ability plays a very important role in the regulation of climate mitigation because the ability of mangrove sequestrators can be utilized to absorb CO2 anthropogenic emissions. Telok Bangko, Loktuan Village, North Bontang, East Kalimantan is an area that has a mangrove ecosystem area, but is also surrounded by industrial areas and settlements. For this reason, this study aimed to assess the mangrove tree species, information on biomass, potential carbon stocks, and CO2 absorption values at that location. Sampling was carried out using the crossed quadrant transect method. At each location the transect was carried out four times. Each transect has four crossed quadrants measuring 10 m x 10 m. In each quadrant, species identification was carried out and then the circumference of the trunk at breast height (Diamter at Breast Height) for mangrove trees (diameter > 4 cm) was measured using a tape measure. Calculation of estimated stored biomass in mangroves using allometric equations using DBH data. Next, estimates of carbon stocks and carbon uptake are calculated. These results will be presented quantitatively descriptive. From this study, 11 species were found, namely Rhizophora mucronata, Avicennia marina, Sonneratia alba, Sonneratia ovata, Derris trifoliata, Ceriops tagal, Lumnitzera racemosa, Xylocarpus granatum, Terminalia catappa, Thespesia populnea, and Wedelia biflora. The results of estimating the carbon stock of the mangrove ecosystem in Bangko Bay were 2236.36 tonnes/ha with a biomass value of 4819.74 tonnes/ha. While in the HGB area, the results of carbon stocks were 2980.48 tonnes/ha with a biomass value of 6423.44 tonnes/ha. Estimated mangrove CO2 absorption in Bangko Bay was 8207.44 tons/ha. Meanwhile, mangrove CO2 absorption in HGB land was 10938.35 tons/ha.

Published: November 2023

Abstract
The textile industry has a strategic role in Indonesia’s economic growth, from employment to high export value, with Bandung City as one of its icons with export commodities during 2018-2021 reaching $82.3 million, which also have various negative impacts on the environment. Total textile waste globally, 88% ends up in landfills and incinerators, and it will increase to 68% in 2030 if business as usual is maintained. Post-consumed textile waste covers 88% of the total waste and tends to be more difficult to manage than pre-consumed textile waste due to hygiene and collection constraints that depend on the consumers of these textile products. This study aims to determine the amount of post-consumed textile waste generation along with the fate behaviour carried out by the consumer and formulate a post-consumed textile waste management strategy to reduce 31.89% of greenhouse gas and waste generation according to Indonesia’s NDC 2030 target. Waste generation and its handling behaviour by the community were determined using a random sampling survey and projected based on the value of industrial growth and population growth in Bandung City towards 2030. The results were analysed based on emission factors and other environmental impacts based on IPCC, USEPA, and other supporting journals. The study reveals that the generation of post-consumed textile waste in Bandung is 19.87 Gg/year (7.90 kg/person/year) and the fate behaviours currently rely on individual behaviours in donated, sold, reused, disposed of and other treatments. The study proposes a strategy to improve the system by preventing burning and dumping into rivers, increasing sorting to be processed into new textile products, and treating in landfill using incinerator. The strategy can save 144 billion litters of water, 9.256 thousand tons of chemicals, 314.21 tons of dyes, 355.6 m2/year of landfills, and save Rp.1.273 trillion/year of textile production costs, and most importantly, can keep GHG emissions at 0.435 Gg/year and waste generation at 3.552 Gg/year.

AbstractLeachate generated from Municipal Solid Waste (MSW) landfill may cause various negative impacts, therefore it should be treated properly in a Leachate Treatment Plant (LTP). The paper aims to select a more sustainable LTP system in Indonesia by applying Analytic Network Process (ANP) as multicriteria analysis approach. 5 alternative LTP systems were analyzed using 5 criteria namely economic, environmental, social, technical, and institutional capacity with a total of 25 sub-criteria. Total 36 respondents from municipality staffs, academics, professionals, and LTP operators were interviewed by adopting pair wise comparison. The results from Driving Dependence Power Analysis (DDPA) showed that sub-criteria for operating costs (E2), maintenance costs (E3), processing effectiveness (T1) and monitoring needs (T3) have the highest dependence power value. Sub-criteria of the operational cost (E2) and the availability of regulations (K2) have the highest driving power value. Main considerations for selecting LTP system at a final disposal site by respondents were economic criteria (weight 0.3219) and water protection sub-criteria (L2, weight 0.17). Top priority of the technology chosen by respondents were Alternative#1 consist of Anaerobic, Facultative and Maturation ponds and Biofilter.
A sustainable approach to managing city park waste through biochar as a renewable energy source
Authors: Hasfita F , Sembiring E , Damanhuri E 
Published: November 2023

Abstract
An abundant natural resource known as lignocellulosic biomass is seen to be a promising and sustainable alternative to renewable energy. A carbon-rich, porous substance called biochar is created when biomass is thermally decomposed during pyrolysis procedures in order to make biofuels. Biochar can be made in big industrial facilities or on a local scale. In order to limit the usage of fossil fuels and find a solution for managing urban park garbage, this project will examine the potential of biochar made from waste from city parks as a renewable energy source. A 25-gram natural zeolite catalyst was used to produce biochar at temperatures between 100 and 500 °C with sample weights of 50, 100, 150, and 200 grams. Calorimetric analysis, FTIR analysis, SEM analysis, XRF analysis, ultimate analysis, and proximate analysis are used to characterize the product. The results showed that the zeolite process produced the maximum calorific value of biochar at 6009.8 cal/gram, the highest yield of biochar at 200 °C, and the weight of 50 grams of biomass without a catalyst at 96%. Aliphatic OH and CH groups associated with phenols, alcohols, and carboxylic acids can be seen using FTIR analysis. Large holes can be seen in leaf litter biochar according to SEM examination. For biochar products, the XRF examination of the metal elements Al, Si, P, S, Cl, K, Ca, Ti, Mn, Fe, Co, Zn, Rb, Sr, Na, Mg, Sr, and Pb is within the permitted limits. Leaf waste can be converted into a non-toxic renewable energy source because biochar has a low sulfur concentration of 4.0%. The findings of this study are anticipated to fill in some gaps left by earlier studies, particularly with regard to the use of garbage from municipal parks and the advancement of renewable energy sources..

Published: November 2023

Abstract
Plastic waste is well known as generated from domestic activities; however, agricultural activities, including fertilizing, spraying pesticides, and soil covering, have the potential to generate plastic waste. Many studies indicated that agricultural plastic waste (APW) can cause pollution of agricultural land, impacting soil health, biodiversity, and productivity. Therefore, this study aims to estimate the loading rate of APW and its potential for recycling. The data was collected from farmers in Karangdowo district, Klaten City, Central Java province, Indonesia, based on clustering and random samples. Data on land area, crop type, planting frequency, pesticide and fertilizer application was determined to estimate APW loading rate. Mapping of the estimation of the loading rate of APW and plastic-type in each village was processed using QGIS software. The results show four types of plastic with a total estimation per year: plastic sacks (949.6 kg/year), plastic bottles (182.9 kg/year), plastic bags (697.0 kg/year), and mulch (12913.6 kg/year). There were three types of plastics: High Density polyethylene (HDPE), Low Density Polyethylene (LDPE), and polypropylene (PP). Although the horticulture area was less than 10% of total agricultural area in each village, it generated the highest LDPE from the use of mulch. Ringinputih village has the highest estimation of recycle potential HDPE, LDPE, and PP compared with the other villages due to having the most significant horticultural area and variation of crops.
Not just platform, nor cooperatives: worker-owned technologies from below
Authors: Grohmann Rafael 
Published: November 2023

Abstract
This article theorizes about how platform cooperativism is landing in Brazil, challenging dominant notions and presenting a more diverse meaning of worker-owned technologies from below. Drawing on research with platform co-ops under construction in Brazil, the article argues that, in Brazil, platform cooperativism does not necessarily present itself as either a cooperative or a platform. They are prototypes and experiments of worker-owned technologies anchored in local communities and their values. Instead of all these experiences being condensed and captured from Global North epistemic frameworks, there is the production of knowledge by the workers in search of autonomy. The article analyzes potentialities and critiques of platform cooperativism, especially from three dimensions of critique (economics, politics, and technology). It presents perspectives towards diversifying and expanding the meanings of technology in/from Latin America for understanding worker-owned technologies. It discusses two examples of worker-owned technologies: Senoritas Courier and the Homeless Worker Movement.

Published: November 2023

Abstract

Aims
Cardiotoxicity is one major reason why drugs do not enter or are withdrawn from the market. Thus, approaches are required to predict cardiotoxicity with high specificity and sensitivity. Ideally, such methods should be performed within intact cardiac tissue with high relevance for humans and detect acute and chronic side effects on electrophysiological behaviour, contractility, and tissue structure in an unbiased manner. Herein, we evaluate healthy pig myocardial slices and biomimetic cultivation setups (BMCS) as a new cardiotoxicity screening approach.

Methods and results
Pig left ventricular samples were cut into slices and spanned into BMCS with continuous electrical pacing and online force recording. Automated stimulation protocols were established to determine the force–frequency relationship (FFR), frequency dependence of contraction duration, effective refractory period (ERP), and pacing threshold. Slices generated 1.3 ± 0.14 mN/mm2 force at 0.5 Hz electrical pacing and showed a positive FFR and a shortening of contraction duration with increasing pacing rates. Approximately 62% of slices were able to contract for at least 6 days while showing stable ERP, contraction duration–frequency relationship, and preserved cardiac structure confirmed by confocal imaging and X-ray diffraction analysis. We used specific blockers of the most important cardiac ion channels to determine which analysis parameters are influenced. To validate our approach, we tested five drug candidates selected from the Comprehensive in vitro Proarrhythmia Assay list as well as acetylsalicylic acid and DMSO as controls in a blinded manner in three independent laboratories. We were able to detect all arrhythmic drugs and their respective mode of action on cardiac tissue including inhibition of Na+, Ca2+, and hERG channels as well as Na+/Ca2+ exchanger.

Conclusion
We systematically evaluate this approach for cardiotoxicity screening, which is of high relevance for humans and can be upscaled to medium-throughput screening. Thus, our approach will improve the predictive value and efficiency of preclinical cardiotoxicity screening.

Abstract

Background and Aims
We explored the potential for differential efficacy of vedolizumab between early and late ulcerative colitis [UC] with evaluation of clinical, endoscopic, and histological endpoints.

Methods
This was a multicentre, multinational, open-label study in patients with moderately-to-severely active UC, defining early UC by a disease duration &lt;4 years and bio-naïve and late UC by a disease duration &gt; 4 years and additional exposure to tumour necrosis factor antagonists. Patients received standard treatment with intravenous vedolizumab for 52 weeks [300 mg Weeks 0, 2, 6, every 8 weeks thereafter without escalation]. The primary endpoint was corticosteroid-free clinical remission with endoscopic improvement [total Mayo score ≤2 with no subscore &gt;1] at both Weeks 26 and 52.

Results
A total of 121 patients were included: in the “early” group, 25/59 [42.4%] achieved the primary endpoint versus 19/62 [30.6%] in the “late” group [p = 0.18]. There were no significant differences between the two groups in endoscopic improvement [Week 26: “early” 32/59 [54.2%] versus “late” 29/62 [46.8%]; p = 0.412; Week 52: 27/59 [45.8%] versus 25/62 [40.3%]; p = 0.546] or in histological remission [Robarts Histopathology Index &lt;3 without neutrophils in the epithelium and lamina propria] [Week 26: 24/59 [40.7%] versus 21/62 [33.9%]; p = 0.439; Week 52: 22/59 [37.3%] versus 22/62 [35.5%]; p = 0.837].

Conclusions
No significant differences in clinical, endoscopic, and histological outcomes were observed between “early” and “late” disease.

Abstract

Aims
Left bundle branch pacing (LBBP) has been shown to better maintain electrical synchrony compared with right ventricular pacing (RVP), but little is known about its impact on mechanical synchrony. This study investigates whether LBBP better preserves left ventricular (LV) mechanical synchronicity and function compared with RVP.

Methods and results
Sixty patients with pacing indication for bradycardia were included: LBBP (n = 31) and RVP (n = 29). Echocardiography was performed before and shortly after pacemaker implantation and at 1-year follow-up. The lateral wall–septal wall (LW–SW) work difference was used as a measure of mechanical dyssynchrony. Septal flash, apical rocking, and septal strain patterns were also assessed. At baseline, LW–SW work difference was small and similar in two groups. SW was markedly decreased, while LW work remained mostly unchanged in RVP, resulting in a larger LW–SW work difference compared with LBBP (1253 ± 687 mmHg·% vs. 439 ± 408 mmHg·%, P &lt; 0.01) at last follow-up. In addition, RVP more often induced septal flash or apical rocking and resulted in more advanced strain patterns compared with LBBP. At 1 year follow-up, LV ejection fraction (EF) and global longitudinal strain (GLS) were more decreased in RVP compared with LBBP (ΔLVEF: −7.4 ± 7.0% vs. 0.3 ± 4.1%; ΔLVGLS: −4.8 ± 4.0% vs. −1.4 ± 2.5%, both P &lt; 0.01). In addition, ΔLW–SW work difference was independently correlated with LV adverse remodelling (r = 0.42, P &lt; 0.01) and LV dysfunction (ΔLVEF: r = −0.61, P &lt; 0.01 and ΔLVGLS: r = −0.38, P = 0.02).

Conclusion
LBBP causes less LV mechanical dyssynchrony than RVP as it preserves a more physiologic electrical conduction. As a consequence, LBBP appears to preserve LV function better than RVP.

Abstract

Aims
Epicardial adipose tissue (EAT) has emerged as a mediator between systemic inflammatory disorders and cardiovascular disease, and may therefore play a role in the pathophysiology of cardiac involvement in systemic sclerosis (SSc). The aim of this study was to assess the correlation between EAT and left ventricular (LV) function, and to determine the prognostic value of EAT in patients with SSc.

Methods and results
Consecutive patients with SSc who underwent non-contrast thorax computed tomography and echocardiography were included. EAT mass was quantified using dedicated software. The study endpoint was all-cause mortality. A total of 230 SSc patients (age 53 ± 15 years, 14% male) were included. The median value of EAT mass was 67 g (interquartile range: 45–101 g). Patients with increased EAT mass (≥67 g) showed more impaired LV diastolic function as compared with patients with less EAT mass (&lt;67 g), and even after adjusting for age and comorbidities, EAT mass was independently associated with LV diastolic function parameters. During a median follow-up of 8 years, 42 deaths occurred. Kaplan–Meier analysis showed that patients with increased EAT mass had higher all-cause mortality rate as compared with patients with less EAT mass (29% vs. 7%; P &lt; 0.001). In the multivariable analysis, EAT was independently associated with all-cause mortality after adjusting for important covariates (HR: 1.006; 95% CI: 1.001–1.010).

Conclusion
In patients with SSc, EAT is independently associated with LV diastolic dysfunction and higher mortality rate.

Published: November 2023

Abstract

Background
Prevalence of adolescent obesity has markedly increased from 5.2% in 1974 to 19.7% in 2021. Understanding the impacts of obesity is important to orthodontists, as growth acceleration and greater pre-pubertal facial dimensions are seen in children with elevated body mass index (BMI).

Methods
To identify whether adolescent obesity shifts the timing and rate of craniofacial growth resulting in larger post-treatment dimensions, we evaluated cephalometric outcomes in overweight/obese (BMI &gt; 85%, n = 168) and normal weight (n = 158) adolescents (N = 326 total). Cephalometric measurements were obtained from pre- and post-treatment records to measure growth rates and final dimensions and were statistically evaluated with repeated measures analysis of variance and linear regression models.

Results
Overweight and obese adolescents began and finished treatment with significantly larger, bimaxillary prognathic craniofacial dimensions, with elevated mandibular length [articulare-gnathion (Ar-Gn)], maxillary length [condylion-anterior nasal spine (Co-ANS), posterior nasal spine-ANS (PNS-ANS)], and anterior lower face height (ANS-Me), suggesting overweight children grow more overall. However, there was no difference between weight cohorts in the amount of cephalometric change during treatment, and regression analyses demonstrated no correlation between change in growth during treatment and BMI. BMI percentile was a significant linear predictor (P &lt; 0.05) for cephalometric post-treatment outcomes, including Ar-Gn, Co-ANS, ANS-Me, upper face height percentage (UFH:total FH, inverse relationship), lower face height percentage (LFH:total FH), sella-nasion-A-point (SNA), and SN-B-point (SNB).

Limitations
The study is retrospective.

Conclusions
Growth begins earlier in overweight and obese adolescents and continues at a rate similar to normal-weight children during orthodontic treatment, resulting in larger final skeletal dimensions. Orthodontics could begin earlier in overweight patients to time care with growth, and clinicians can anticipate that overweight/obese patients will finish treatment with proportionally larger, bimaxillary-prognathic craniofacial dimensions.
Unhealthy sleep assimilation

Published: November 2023

Abstract
Migrant health advantages, the ‘healthy immigrant effect’, erode over time, leading to what is known as unhealthy assimilation. Health-related behaviours are central to unhealthy assimilation, and here we focus on an understudied and central part of our daily time: sleep. Building on diverse streams of literature, we conceptualize and empirically study the sleep assimilation patterns of immigrants. With data from Germany, we demonstrate that immigrants sleep significantly more than natives upon arrival, while their sleep ‘advantage’ dissipates with years spent in the host country. We also explore the heterogeneity of the sleep assimilation process by gender, education, wages, work schedules, and job physical intensity.
