Published: June 2023

Abstract
In Wrocław over the past 20 years, the recorded increase in the average ambient air temperature is approx. 0.5 °C. In addition, urbanisation has created a phenomenon called the Urban Heat Island (UHI). The combined effect of the UHI and climate change can influence groundwater temperature by penetrating underground. The phenomenon of elevated groundwater temperatures in urban areas is called the Subsurface Urban Heat Island (SSUHI). This study focuses on the spatial distribution of temperature in shallow aquifers in the city of Wroclaw. The spatial distribution was analysed based on groundwater temperature maps developed with various interpolation techniques. The results of measurements in a network of 65 piezometers conducted in the 2004-2005 hydrological year have been used in this study. The temperatures recorded show seasonal variation with the lowest recorded in February (1.3 °C) and the highest in August (24.5 °C) with the annual average of 13.2 °C. The data has been processed with the Inverse Distance Weighted (IDW), Radial Basis Function (RBF) and Kriging interpolation methods. Furthermore, the cokriging method based on multivariate linear regression models has been used to assess if variable such as distance from the city centre improve the interpolation performance expressed as the lowest RMS error value. It has been established that the Kriging univariate regression model based interpolation method produced the best results (RMS error equal to 1.33 °C) and that the distance from the city centre has improved the accuracy of interpolation.

Abstract
Social changes in the context of climate change include the character of capitalism and the relationship between nature and culture that encourages people to respond to climate change and adapt their livelihoods. The purpose of this study is to calculate coral density in the context of ecological resilience and its effect on sustainable tourism in Pari Island, DKI Jakarta. The research method uses a survey with the Line Intercept Transect method. Sampling was carried out at a depth of 5 and 7 meters, depending on the presence of coral. The length of transect used is 50 meters and is placed parallel to the shoreline of the island. The results showed: First, most of the coral reefs in Pari Island are still in good and healthy condition. Of the 15 sample points observed, only 2 showed coral mortality due to internal and external factors in the sea. From the results of the analysis it was concluded that the condition of healthy coral reefs in the waters of Pari Island had a high density. Meanwhile, stressed or dead coral reefs have a low density. This condition indicates that coral reefs are still effective in supporting tourism activities.

Abstract
The rapid development of the city of Yogyakarta has resulted in the conversion of land functions from built-up land to undeveloped areas such as residential areas, office areas, and industrial areas. This land-use change is predicted to impact changes in weather and climate in most of the cities of Yogyakarta and cause the Urban Heat Island (UHI) phenomenon. Urban Heat Island will have implications for thermal comfort which can affect the productivity of community activities. This study aims to determine the correlation between UHI and the level of thermal comfort of settlements in Yogyakarta. This research was conducted to determine the level of thermal comfort in the city of Yogyakarta using remote sensing and GIS approaches. Comfort classification was obtained from the THI analysis and analyzed the correlation between THI and UHI. The UHI variable is used to calculate the Temperature Humidity Index (THI). The results of the quantitative analysis showed that Yogyakarta City UHI had a strong positive correlation (r2= 0.93) with the level of THI and a weak negative correlation with RH (r2= 0,52). T The increase in the level of UHI shows that the humidity and thermal comfort of the city of Yogyakarta is decreasing. The results of the qualitative analysis of the study also show that more than 95% of the people feel comfortable with the thermal conditions in which they live.

Abstract
Beach tourism potential in Desa Gajahrejo, Kecamatan Gedangan, Kabupaten Malang can optimize its domestic income if developed and managed properly. Therefore, it is essential to map and thus analyze its tourism potential. This research used four physical indicators to determine the classification of the beach tourism potential of Gajahrejo: 1) distance from the city center, 2) amenities, 3) accessibility, and 4) attractiveness. After data collection using a survey method, the data was scored based on its potential values. After that, it was classified into five tourism potential classes from “very low” to “very high”. Out of 14 beaches in Gajahrejo, two are considered to have “low” potential, five are considered to have “moderate” potential, and seven are considered to have “high” potential. Amenities and accessibility indicators had the most influence on the final tourism potential score of the area. As a recommendation, each beach needs to have a distinctive tourist attraction to meet diverse tourist segmentations. Moreover, it is vital to improve the accessibility of each beach tourism destination by connecting it to the province’s main road.

Published: June 2023

Abstract
The degraded mining area, especially the disposal area, must be reclaimed to preserve the possibility of its subsequent use in the future. The open pit rehabilition must ensure post-mining contributes powerfully to the ecosystem by restoring the production capacity and stability of the area. The exercise was applied to a nearly 0.5 Ha of open-pit coal mine conducted in cooperation between Korea and Indonesia to create a production forest that can ultimately support the environment. The objective of this work was to design mine pit reclamation plan through characterization physically and chemically the location by regenerating, checking the drainage system, analyzing soil fertility and the possibility of soil contamination and discovering fast growing local crop and forest plant species. The main focus is more on analyzing the soil condition affected by the acid mine drainage problem. The results showed that the northern restoration target site had the steep slope, characterized as acidic soil (pH was 4.2 – 4.6) with low exchangeable cation and low phosphate availability. The heavy metals did not exceed the contamination limit, so separate processing to prevent leaching of heavy metals is not required. Routine monitoring of the drainage system is important because it will affect the watering frequency and leaching control. Understanding the step by step mine rehabilitation can assist in designing reclamation efforts especially for revegetation purpose.

Published: June 2023

Abstract
Environmental has been a global issue. The industry entities have damaged the ecosystem severely, so the right approach to solve this problem is necessary. This study aims to discuss on the prospects of green restorative justice as the settlement of environmental cases, especially in broken environments due to the industry company activities. This qualitative study used the exploratory method about the chance of green restorative justice to settle the problem between corporations and communities which were damaged in their living area. The findings showed that green restorative justice could be another way to solve the environmental issues because the non-trial process took less time and low cost. Following that, another finding was that implementing re-greening of the ecosystem by the guilty company could be faster and more beneficial for the community as long as the other stakeholders involved, such as the government and media guarding the cases. Furthermore, this study can be used as a future way to face the conflict between the corporation and the society where the environment is the victim, so that sustainable development can be attained.

Published: June 2023

Abstract
Karst area provides numerous ecosystem services from the interaction among its components of water, soil, and vegetation. However, a threat from unsustainable practice and resource overuses could diminish those services. Therefore, it is critical to steadily monitor the karst dynamics, especially in high-activity karst like the Karst of Tuban. This study aims to capture the karst dynamic, particularly the land-use change and how its impact on ecosystem services (ES). To achieve the research objective, an artificial intelligence tool of ARtificial Intelligence for Ecosystem Services (ARIES) is employed. ARIES examines a dataset for 6 years intervals beginning in 2012 to 2018 consisting of land-use and ecosystem change and ES using 150 m spatial resolution data. During that period, Tuban Regency undergoes a heavy change in artificial surface and a significant decrease in the water body and cropland. From the result, ARIES as the ES estimation tool can be used for robust calculation and preliminary study due to its limitation. The results also show the urge to address the issue of carbon storage and sediment regulation in the karst area and the land-cover changes in the Tuban Regency.

Published: June 2023

Abstract
Soil as a medium for plant growth is the most important factor in agriculture. Soil capability is closely related to soil fertility which describes soil productivity in producing optimal agricultural production. Cugenang District is located in Cianjur Regency, which has abundant rice crops. Cugenang District also experiences changes in land use and disasters that can decrease the land’s ability. This study aims to map and analyze the capability of the soil and land management of paddy fields and the relationship between the two. This quantitative research uses spatial, statistical, and descriptive analysis. Data were collected by observation, soil sampling, interviews, and secondary data sourced from related institutions. The collected data will be processed using statistical tests and geospatial technology using ArcGIS 10.8 to visualize soil capability and land management of paddy fields geographically. The weighted overlay technique’s spatial analysis results show that most paddy fields have medium and low soil capability. Meanwhile, high soil capability for paddy fields is mostly found in high areas of Cugenang District. The land management of paddy fields is calssified into two combinations. The first combination is between vegetative conservation and fertilization. The second combination is between vegetative conservation, mechanics conservation, and fertilization. Statistical test using chi-square shows a strong relationship between soil capability and land management. The results of this study indicate that the majority of paddy fields with medium soil capability use three methods of land management techniques, while paddy fields with low soil capability use two methods of land management techniques.
Fermi polaron fine structure in strained van der Waals heterostructures
Authors: Iakovlev Z A , Glazov M M 
Published: June 2023

Abstract
The fine structure of attractive Fermi polarons in van der Waals heterostructures based on monolayer transition metal dichalcogenides in the presence of elastic strain is studied theoretically. The charged excitons (trions), three particle bound states of two electrons and a hole or two holes and an electron, do not show any strain-induced fine structure splitting compared to neutral excitons whose radiative doublet is split by the strain into linearly polarized components. The correlation of the trions with Fermi sea holes gives rise to attractive Fermi polarons. We show that this results in a fine structure splitting of the polaron into states polarized along the main axes of the strain tensor. This effect is related to the bosonic statistics of Fermi polarons. We develop a microscopic theory of the effect and calculate the strain-induced splitting of Fermi polarons for both tungsten- and molybdenum-based monolayers, identifying the role of inter- and intravalley exciton–electron interactions. The fine structure splitting of the attractive Fermi polaron is proportional to both the excitonic splitting and the Fermi energy. The Fermi polaron fine structure in bilayers is briefly analyzed, and the role of electron and trion localization in moiré potentials is discussed.

Published: June 2023

Abstract
Most of the research of building materials companies at present focuses on recycling waste to minimize the cost of their products and for the safe disposal of these wastes. In this work, the by-pass cement kiln dust (BCKD), the dust that is discarded from the kiln system was used for the preparation of roof tiles. It is partially used to substitute clay in percentages from 5% up to 25%. to prepare roof tiles abiding by ASTM C1167 for two objectives, the safe disposal of waste and the production of low-cost roof tiles. The raw materials were assessed by particle size analysis, XRD, and XRF. The mud was poured into moulds with dimensions of 150 * 30 * 25 mm3 and pressed under a pressure of 10 MPa then dried. The dried samples were fired to temperatures 1000, 1100, and 1150 °C with a soaking time of one hour for each temperature. The linear firing shrinkage, water absorption, bulk density, and breaking strength were measured to determine the properties of the fired specimens. The initial rate of absorption and runoff properties were also determined for the optimal samples. The results showed that samples containing 8% and 12% of BCKD waste that fired at 1100 °C and 1150 °C had cold water absorption of 14% and a saturation coefficient of 0.85, both of which were below the maximum values of the standard limits. Furthermore, the measured breaking strength of about 2700 N was much higher than the necessary minimum value. The results showed that samples met the requirements of ASTM 1167 for clay-type roof tiles containing 8% BCKD waste and fired to 1100 °C. For economic and environmental benefits, 1100 °C firing temperature is recommended than 1150 °C. The initial rate of absorption was found to be 2.8 kg.m−2 and the runoff properties were found to be 0.02 mg.l−1, 7.53, 110.5 mg.l−1 for total dissolved solids, pH and total solids respectively.
Exploring battery cathode materials in the Li-Ni-O phase diagrams using structure prediction
Authors: Cen Jiayi , Zhu Bonan , Scanlon David O 
Published: June 2023

Abstract
The Li-Ni-O phase diagram contains several electrochemically active ternary phases. Many compositions and structures in this phase space can easily be altered by (electro-)chemical processes, yielding many more (meta-)stable structures with interesting properties. In this study, we use ab initio random structure searching (AIRSS) to accelerate materials discovery of the Li-Ni-O phase space. We demonstrate that AIRSS can efficiently explore structures (e.g. LiNiO2) displaying dynamic Jahn-Teller effects. A thermodynamically stable Li2Ni2O3 phase which reduces the thermodynamic stability window of LiNiO2 was discovered. AIRSS also encountered many dynamically stable structures close to the convex hull. Therefore, we confirm the presence of metastable Li-Ni-O phases by revealing their structures and properties. This work will allow Li-Ni-O phases to be more easily identified in future experiments and help to combat the challenges in synthesizing Li-Ni-O phases.
