The conceptualization of smart tourism service platforms on tourist value co-creation behaviours: an integrative perspective of smart tourism services
Authors: Chuang Chung-Ming 
Published: June 2023

AbstractThe question remains how to integrate the core service proposals within a smart tourism platform setting for further facilitating tourist value co-creation behaviours in sustainable ways. This paper investigates the paradigm of smart tourism service (STS) platforms within the context of an ecosystem space. It conceptualizes concepts by laying a reasonable theoretical foundation (service-dominant logic) and proposing a scale for smart services. Applying sequential mixed methods to an exploratory research design, with seven interlocking stages and data from Fuzzy Delphi experts and tourist surveys in Taipei City, a smart city in Taiwan, this paper proposes a second-order scale with six dimensions, comprising smart services of attractions, transportation, accommodation, diet, purchase, and payment. The final 32-item STS scale is thoroughly developed and subsequently validated in different contexts (i.e. travellers in different phases of travel, pre-travel and during the trip, respectively). The scale significantly reveals the tourist-operated technologies for the provision of STS, determining the development of conceptual STS platforms in this paper. Next, the platforms disclose the locus between ICT functions, information-related services, tourist applications and behaviours, and sustainable value co-creation. The potential path of “STS → behaviour → sustainable value co-creation” explored herein is helpful for illustrating the conceptualization of STS platforms. Moreover, predictions from the platforms of tourists’ smart behaviours make it practically relevant in assessing demands about smart services for tourism. In the end, this paper describes the theoretical implications and managerial implications for tourism practitioners.

Background The Drought Code (DC) of the Canadian Fire Weather Index System (CFWIS) has been intuitively regarded by fire managers in Alaska, USA, as poorly representing the moisture content in the forest floor in lowland taiga forests on permafrost soils. Aims The aim of this study was to evaluate the DC using its own framework of water balance as cumulative additions of daily precipitation and substractions of actual evaporation. Methods We used eddy covariance measurements (EC) from three flux towers in Interior Alaska as a benchmark of natural evaporation. Key results The DC water balance model overpredicted drought for all 14 site-years that we analysed. Errors in water balance cumulated to 109 mm by the end of the season, which was 54% of the soil water storage capacity of the DC model. Median daily water balance was 6.3 times lower than that measured by EC. Conclusions About half the error in the model was due to correction of precipitation for canopy effects. The other half was due to dependence of the actual evaporation rate on the proportional ‘fullness’ of soil water storage in the DC model. Implications Fire danger situational awareness is improved by ignoring the DC in the CFWIS for boreal forests occurring on permafrost.
Promoting equitable literacy expectations in CLIL

Published: June 2023

Abstract
This study explores the impact of two Service-Learning (SL) projects on student teachers’ preparation and
perceptions in relation to literacy teaching in English as a foreign language within CLIL programmes. The projects offered
hands-on training in preparing and delivering lessons applying Rose and Martin’s (2012)
Reading to Learn (R2L) approach to support children at two Madrid primary schools implementing CLIL with high proportions of
at-risk pupils and socioculturally diverse student bodies. One hundred and thirteen undergraduate student teachers specialising in
English as a Foreign Language at the Complutense University School of Education participated in the SL projects. The projects’
goals included developing the students’ civic engagement and disposition to gain understanding of the potential of a systematic,
evidence-based approach to literacy pedagogy for guiding all pupils to acquire the reading and writing abilities needed for
educational success. Data from questionnaires, focus group interviews, and reflective journals were collected and analysed.
Student teachers faced the challenges of apprehending and effectively applying the R2L strategies in classrooms characterised by
pupils’ widely ranging levels of preparation for reading and writing in English. Their reflections show evolution towards
readiness and awareness of the possibilities of adopting proactive measures, such as systematic literacy instruction, in order to
ensure the progress of pupils as they face the challenges of CLIL in the context of socioeconomic and educational inequity within
classrooms and across schools.
Addressing social equity by making explicit the implicit value
systems within content and language learning
Authors: Cross Russell 
Published: June 2023

Abstract
Despite efforts to redress the problem of social inequity within
education, data reveals the student attainment gap continues to widen on the
basis of socioeconomic background, particularly within Anglophone contexts
(OECD, 2019; Wilkinson & Pickett, 2009). Bourdieu’s (1986) concept of ‘cultural
capital’ has been one especially powerful concept for understanding the causes
of such inequity as it relates to social class, and how entrenched patterns of
privilege within institutions, such as schools, value certain forms of cultural
capital – and associated ways of knowing, being, and doing – over others. Much
of the existing CLIL research on social (in)equity has tended to examine either
the impact of programmatic conditions on dis/advantage (e.g., streaming, access;
see also Evniskaya & Llinares, this issue), or the role of language for
enabling more inclusive instructional practices (e.g., differentiation,
scaffolding). Both lines of inquiry have produced valuable insights on how CLIL
can contribute to more equitable outcomes, but this paper aims to offer a third
line, focusing on how greater equity can be achieved through the
conceptualization of culture within CLIL contexts. Informed by Bourdieu’s
concept of ‘cultural capital’ which has helped advance class-based
understandings of inequity, the paper develops a pedagogic framework that
explicitly accounts for culture when there is a simultaneous focus on both
language and content, drawing on examples from instructional practice.

Published: June 2023

Abstract
In the last few decades, gravastars have been proposed as an alternative to black holes. The stability of a gravastar has been examined in many modified theories of gravity along with Einstein's GR. The

gravity, a successfully modified theory of gravity for describing the current accelerated expansion of the universe, has been used in this study to examine gravastar in different aspects. According to Mazur and Mottola [Proc. Natl. Acad. Sci. 101, 9545 (2004); Gravitational condensate stars: An alternative to black holes, I12-011, (2002)], a gravastar has three regions with three different equations of state. In this study, we examined the interior of a gravastar by considering

EoS to describe the dark sector for the interior region. The next region is a thin shell of ultrarelativistic stiff fluid, in which we investigated several physical properties, including proper length, energy, entropy, and surface energy density. Additionally, we examined the surface redshift and speed of sound to check the potential stability of our proposed thin-shell gravastar model. Furthermore, we used the entropy maximization technique to verify the stability of the gravastar model. A gravastar's outer region is a complete vacuum described by exterior Schwarzschild geometry. Finally, we presented a stable gravastar model, which is singularity-free and devoid of any incompleteness in classical black hole theory.
Nucleons as modified Ising models*
Authors: Hu Shu-Man , Luan Yin-Sen , Xu Ji 
Published: June 2023

Abstract
In this paper, we propose a map that connects nucleons bound in nuclei and Ising spins in the Ising model. This proposal is based on the fact that the description of states of nucleons and Ising spins could share the same type of observables. We present a nuclear model corresponding to an explicit modified Ising model and qualitatively confirm the correctness of this map with a simulation on a two-dimensional square lattice. This map can help us understand the profound connections between different physical systems.

Abstract
The cross-sections of the 127I (n, 2n) 126I and 133Cs (n, 2n) 132Cs reactions at neutron energies of 13.83 ± 0.05, 14.33 ± 0.10, and 14.79 ± 0.10 MeV were measured relative to the 93Nb (n, 2n) 92mNb reaction using the activation technique in combination with off-line γ-ray spectrometry. A neutron beam was generated from the T (d, n) 4He reaction using the K-400 neutron generator at the China Academy of Engineering Physics. Considering the correlations between different attributes, detailed uncertainty propagation was performed using covariance analysis, and the cross-sections were reported with their uncertainties and correlation matrix. The uncertainty of the measurement cross-sections ranged from 4.84 to 5.90%, which is lower than previous experimental data. Furthermore, the theoretical excitation functions of the 127I (n, 2n) 126I and 133Cs (n, 2n) 132Cs reactions were calculated using the TALYS-1.95 and EMPIRE-3.2.3 codes. Then, the experimentally determined cross-sections were analyzed by comparing them with literature data available in the EXFOR database and evaluated nuclear data in the ENDF/B-VIII.0, JEFF-3.3, JENDL-5, BROND-3.1, CENDL-3.2, and TENDL-2021 databases. Compared with the values previously reported in the 13.8-14.8 MeV energy region, the precision of the results obtained in this study was greatly improved. The current experimental results with thorough uncertainties and covariance information are critical for verifying the reliability of the theoretical model and improving the quality of the nuclear database.

Abstract
Landfill in Bantargebang integrated solid waste treatment facility received 85% of the municipal solid waste of Jakarta Province in 2021. Since it is almost filled, the government operated a landfill mining (LM). This research aimed to characterize and evaluate the humate soil potential from mined material (MM) for agriculture. The weight, volume, and density of MM were measured on randomly selected collection vehicles in the LM location for eight consecutive days on March 2–15, 2022. Composition analysis was conducted by sieving and classifying samples into fine (FF), medium (MF), and coarse fractions (CF) of < 10 mm, 10–30 mm, and > 30 mm, respectively. MM had a weight, volume, and density of 81.43±13,03 tons/day, 147.84±33.31 m3/day, and 0.56±0.06 tons/m3, respectively. FF had soil-like material of 13.96±1.12%, while MF was 18.74±1.10%. Both fractions contained moisture, volatile solids, ash, carbon, nitrogen, and C/N ratio of 56.92–63.47%, 69.17–74.81%, 25.19–30.83%, 52.87– 55.67%, 1.89–2.10%, and 25.17–29.46, respectively. These characteristics met compost quality standards, except for high moisture content, which made it suitable for agriculture after moisture reduction. Meanwhile, plastics and wood-dominated CF were suitable for non-agriculture. A toxicological test is recommended to ensure the humate soil’s safe use.
Chemical of concern for raising awareness to Indonesian textile sustainability
Authors: Suciati F , Aviantara D B , Suherman  , Purnomo A , Krauss M 
Published: June 2023

Abstract
It is well known that textiles and textile products may contain hazardous compounds. Formally, all imported textiles and textile products must be registered through the Indonesian Custom. Ideally, the Indonesian Custom has the capability to detect chemicals of concern in textiles or textile products entering Indonesian territory. However, this is not the case, particularly for chemicals listed in the Stockholm Convention. The difficulties arise from the lack of identification regarding substances listed in the Stockholm Convention that might be present in textiles, textile products, and finished products. The Indonesian Government has initiated programs to assess the presence of persistent organic pollutants (POPs) in Indonesian territory. Results of the assessment were elaborated in the National Implementation Plan Document on POPs, which was updated recently. Not all substances listed in the Stockholm Convention can be described in depth. Some POPs such as short-chain chlorinated paraffins (SCCPs) and polychlorinated naphthalenes have not been included in Indonesian regulation, particularly in Indonesian Customs Tariff Book, making it extremely difficult to assess them. Nevertheless, a preliminary assessment of polybrominated diphenyl ethers and SCCPs has been carried out. Using the Tier 1 approach, it was revealed that 2,194 tonnes of SCCPs was imported from India to Indonesia, which was listed under HS code 38249090 that covered CP52 (containing 50–54% chlorinated paraffins). Furthermore, another prominent issue for chemicals of concern (CoC) in textiles was the use of lead-containing dyes, nonylphenols, and nonylphenol ethoxylates. The latter two compounds are known to be used in detergents and surfactants during textile manufacturing processes. At present, nonylphenols and nonylphenol ethoxylates are not listed in Indonesian laws for regulated chemicals in textiles and textile products, as well as in the wastewater quality standard for the textile industry. Therefore, to avoid circular economy obstacles of used textiles and textile products and support sustainable Indonesian textiles, a systematic inventory of CoC in textiles is very important.

Published: June 2023

Abstract
Torrefaction can be considered a promising method to treat municipal solid waste (MSW) which not only solves the MSW management problem but also produces a solid product that has the potential to be used as fuel. This study aimed to examine the char properties and quantities from torrefaction of MSW (particularly plastic waste categorised as LDPE and PET, and kitchen waste) as well as the effects of process temperature on char products. Approximately 150 g of feedstock was placed inside the reactor for each torrefaction experiment with different temperatures (175, 200, and 225 °C). Torrefaction at 225 °C increased the higher heating values (HHV) of LDPE and PET, from 19.17 to 24.50 MJ/kg, while the HHV of food waste increased from 11.18 to 17.04 MJ/kg. Besides the char product, torrefaction of LDPE and PET at the temperature of 225 °C produced liquid products with HHV up to 34 MJ/kg. The char yield after the torrefaction of plastics (LDPE and PET) and food waste at a temperature of 225 °C were 14.77% and 30.03%, respectively.

Abstract
Coconut shell contains several components of biomass including cellulose, lignin, and pentosan, which can be used in the form of charcoal as a bioabsorbent. Sludge waste is a residue formed as a by-product of wastewater treatment at a wastewater treatment plant (WWTP). which emits odors that can disturb local residents. This study aimed to deodorize ice cream slurry waste using coconut shell charcoal and activated carbon as the odor adsorbent. The ratio of each adsorbent and ice cream waste was based on the preliminary experiment, namely 1:1, 1:3, 1:5, 1:6, and 1:7. The measurement parameters for the sludge were odor value, pH, temperature, and water content which were measured daily. Ammonia and sulfide levels were measured using the titration method, while protein levels were determined using a UV-Vis spectrophotometer. Odor reduction in sludge waste mixed with activated carbon as the adsorbent was better than that with coconut shell charcoal; by which the optimum mass ratio was 1:3 with a decrease of 97.13% that was obtained within seven days. The ammonia levels in the sludge waste decreased from 10,276 mg/kg to 308 mg/kg by the use of coconut shell charcoal with a mass ratio of 1:1 and to 252 mg/kg by the use of activated carbon with a mass ratio of 1:1 at the end of the experiment. The sulfide content in the sludge waste decreased from 1.215 mg/L to 0.0483 mg/L in the sample with coconut shell charcoal as an adsorbent with a mass ratio of 1:1 and to 0.0483 mg/L in samples with activated carbon adsorbent ratio of 1:1 at the end of the experiment.
Trihalomethanes formation potential of polluted tropical river water and its correlation with UV-Vis spectral ratio: A case study in Citarum River, Indonesia
Authors: Qadafi M , Rosmalina R T , Rohman O , Wulan D R 
Published: June 2023

Abstract
The presence of natural organic matter (NOM) and anthropogenic organic matter (AOM) in polluted river water leads to the formation of carcinogenic disinfection by-products (DBPs) during the water chlorination process. This study aimed to determine trihalomethanes (THMs) formation, as the regulated DBPs, in polluted tropical river water. The samples were taken from the Citarum River, Bandung, Indonesia. The NOM and AOM were characterized using UV254, UV355, and ultraviolet-visible (UV-Vis) spectral ratio while DBPs formation was determined using THM4 formation potential. In several sampling points, the THM4 formation potential of the samples exceeded the USEPA regulation standards and had high toxicity (LC50) values. On the other hand, other sampling points had small THM4 formations. Also, the THM4 formation potential was found to have a great correlation with the spectral ratio, especially A280/A350 UV absorbances that could be further used as a surrogate parameter of THM4 formation. Citarum River, as a water source, needs sufficient treatment to remove the DBPs precursors to provide healthy and clean potable water.

Abstract
Microplastic pollution in the marine and freshwater environment has been a global concern. The pollution in densely populated urban areas may be more severe than in any other environment, especially in areas lacking plastic waste management. Urban lakes in the Megacity of Jakarta, the capital city of Indonesia, and neighboring areas, which is the most populated city in the world, have been severely polluted by plastic waste. The urban lakes studied were located downstream of watershed areas of major rivers that outflow into Jakarta Bay, the Java Sea, and finally the ocean. To our knowledge, no studies have been reported on microplastic pollution in urban lakes in the Megacity of Jakarta. This study investigated the first occurrence of microplastics in the surface water of six urban lakes in the Megacity of Jakarta. Grab water samples were collected in either inlet or outlet areas of lakes. The water samples were pretreated and sieved to separate the microplastics. The quantification and the identification of microplastics were made using a Stereo Microscope. The most downstream urban lakes in the densely populated area close to Jakarta Bay, which is the final disposal of plastic wastes from the river canal and runoff from the surrounding area, had more microplastics than the urban lakes in the area with less population and further from the Bay. The most abundant microplastics found in the lake’s surface water was about 30,000 particles/m3, whereas 300 - 500 µm and the foam were the dominant size and type of microplastics discovered. The concern is that the smallest size of particles of microplastics found in the lake’s water could potentially contaminate aquatic biota, especially fish, not only in the lakes but also in Jakarta Bay, where fishing activities are substantial.
Prototype design of urban monitoring on several gaseous pollutants using low-cost electrochemical sensors

Published: June 2023

Abstract
Monitoring atmospheric gaseous pollutants in urban areas is increasingly essential to anticipate poor urban air quality and the increasing number of acute respiratory infections caused by air pollution. Usually, the monitoring of air pollution is conducted by the government and scientists by using accurate and expensive instruments. However, this instrument’s high-cost installation and maintenance limited the number of monitoring stations that can be placed. It makes it hard to identify the pollutant’s local source, especially on an urban scale. Hence, this study designed alternative techniques to monitor several gaseous pollutants using the Low-cost Air Quality System (LAQS). LAQS has enormous potential to be a reference station’s supporting tool and increase the resolution of air pollution monitoring systems. A custom-made low-cost electrochemical sensor was used in this study to detect several gaseous pollutants, including ozone (O3), nitrogen dioxide (NO2), and carbon monoxide (CO), together with temperature and relative humidity measurements. The system was also equipped with a data logger and 4G module for data storage and transmission, respectively. In the first stage, two scenarios were employed, including its examination inside and outside the room before co-location.
