Abstract
In urban areas, the urge to improve acoustic environments has led to an increasing interest in the soundscape as an alternative approach to address noise pollution issues. Several studies have shown that the soundscape approach can manage the unwanted sound and transform it into resource sound in the areas, while the urban street context is expected to play an important role too. Thus, this study aims to assess visual perception factors on soundscape (appropriateness, calmness, and eventfulness) of urban shopping street as an environmental factors. Data was collected in three urban shopping streets at Kuala Lumpur, Malaysia through a soundscape survey (n = 411) according to the ISO12913-2 technical specifications standards. Multiple Linear Regression was used to analyse the data. The findings revealed in three aspects, that are: (1) The interesting, beautiful and harmonious indicators under visual quality of environment dimension were highly preferred by the users. (2) All the soundscape dimensions have significant effects on the predictors. Appropriateness (R2=.454) is the most prominent factor, followed by eventfulness (R2=.298) and calmness (R2=.139). (3) All soundscape dimension has a higher impact on visual perception (β=.536, β=.356, and β=.202) than other predictors by comparing the standardised coefficients. The result from the present study showed that visual perception factors could be helpful indicators for better understanding soundscapes and assist the urban planners, architects and landscape architects in designing conducive acoustic environment of urban shopping streets.

Abstract
The suitability of the new cemetery site selection area is one of the management that needs to be emphasized for sustainable development. Lack of suitable land for burial is a major issue that often arises especially in big cities including Malaysia, even though guidelines have been specified. To overcome this problem, the systematic use of technology needs to be implemented. The aim of this study is to analyze the existing modeling method and the factors involved in obtaining a suitable area for a new cemetery site, which has to meet all the specified guidelines. Along with advancement, the uses of Geographic Information System (GIS) technology and the Analytical Hierarchy Process (AHP) in digital form can help speed up the accession to a suitable physical location. This method is expected to help the local authorities and speed up the process of choosing a suitable place for the cemetery. The application of the AHP technique supports the study results through variable weighting values (weightage) according to the suitability of the study area. Evaluation of the weighted value (weightage) is suggested to be done in areas outside of the study area to assess consistency and appropriateness in all places. Proposals related to the location of new cemeteries require a quantitative study of the ratio of racial composition in an area. As a conclusion, the study is able to find a new cemetery location that is suitable and meets the specified guidelines is very crucial. The criteria used depend on the religious followers in a particular area.

Published: May 2023

Abstract
Water quality, treatment plant management, and environmental concerns all affect how well a sewage treatment plant performs. Due to the high degree of nonlinearity in the plant as well as the nonuniformity and unpredictability of the influent amount, quality parameters, and operational conditions, modelling the sludge capacity index of the activated sludge method in municipal wastewater treatment plants is a challenging mission. To assess the effectiveness of the al-diwaniyah wastewater treatment plant (WWTP) operation and to estimate quality parameters, the study’s first goal is to improve the WWTP by using artificial neural networks (ANNs). Second, increasing the efficiency of the ANNs model to determine the best WWTP procedure. ANNS were created to predict the sludge volume index (SVI) using the al-diwaniyah WWTP operational and influent quality characteristics. The neural network’s best model for predicting SVI consists of an input node with six input variables, a hidden layer with five nodes, and an output layer with one variable, with an R2 value of 0.965. The outcomes show how effective the right neural network models are at predicting SVI. This is a highly helpful tool that WWTP operators may use in their daily management to improve the effectiveness of the treatment process and the dependability of the WWTP.

Abstract
Limestone is part of sedimentary rock, namely non-clastic sedimentary rock formed from chemical or biological processes. The main content of limestone is mineral calcium carbonate (CaCO3), which occurs due to chemical or organic processes. In general, the mineral contents in limestone are 95% calcite calcium carbonate, 3% dolomite, and the rest is clay minerals. Measurements with drones are expected to be an alternative method other than using Total Station (TS). This research aims to calculate the mined area acquisition at the mining area of PT. Panca Mitra Makmur by using a drone as a measuring device. For final data processing, ArcGis / ArcMap Application 10.3 was used. The mined area was then calculated to determine the extent. The mine progress formula was used to determine the percentage of limestone mining progress each month. This research refers to the Work Plan and Budget (RKAB) prepared by the company on a monthly basis. The mined area acquisition in May, June, and July 2021 was 1,388 m2. Supposedly from May to July 2021, the target mined area for limestone production was 2,298 m2.

Abstract
One of the roads in the Pemenang District, West Lombok Regency, which connects the districts in West Nusa Tenggara, is the Pusuk highway. Due to the area’s considerably steep slope, landslides frequently occur there as much as the rainy season comes. Almost all incidents of abruptly raising slopes, with or without warning indications preceding them, can result in landslides. This is a critical feature for proper handling. Using the survey method, especially the field survey, the researcher used Bishop Method with a 2D SLIDE application model to analyse the data. It was designed to evaluate the magnitude of landslide vulnerability. The safety factor study yielded a score of 0.889 <1.25, indicating that the slope falls under the heading of risky slopes.

Abstract
Landslides are caused by disruption of the soil’s degree of stability. When a slope’s pushing force exceeds its restraining force, a land slide will result. Moreover, at Human activities, climate change and natural influences can disrupt the stability of the soil and rocks on slopes. Disruption of the level of soil stability causes landslides. A landslide occurs due to the driving force on the slope being greater than the resisting force of the slope. To prevent landslide, a slope stability analysis is necessary. Moreover, the research site tends to produce a gravitational force that moves the soil mass towards a higher surface. This occurs as a result of due to the area’s topography of the area, which has different elevations varying from gentle to step but however, the research location is an andesite rock mining located in Peseng Village, Gerung District, West Lombok Regency, West Nusa Tenggara. The slope stability is required to reveal the shear strength of the slope and its safety factor. The analysis was conducted by using a survey, especially a field method. The field method used was the Bishop method with 2D Slide Program Software. Based on the results of laboratory testing, the value of the bulk weight (ү) is 18.21 kN/m3, dry weight 18.14 kN/m3, wet weight 18.53 phi (Φ) is 13.50° and cohesion (c) is 136.8 kN/m3.

Abstract
PT. Nusa Cendana is a mining company operating andesite mining in Taman Ayu Gerung Village, Gerung District, West Lombok Regency, West Nusa Tenggara Province. Andesite criteria are classified as hard and difficult to separate. PT. Nusa Cendana carries out mining activities with a quarry mining system. PT. Nusa Cendana has a problem on the slopes because the current slope is 85°, and many joints on the slopes cause landslides. Ideally, the slope is 70°. Slope stability is used to determine the slope’s safety factor and ideal geometry. So, before making slopes in mining, it is necessary to analyze first whether the type of rock supports the geometry of the slope. One method is to assess the rock’s strength, namely the rock’s compressive strength test. Based on the results of laboratory tests, the values for the bulk density were 15.97 kN/m3, internal shear angle (ϕ) 40.36°, and cohesion 42.01 kN/m2. The safety factor analysis using slide2D software obtained 1.233 m for the value of the safety factor for slope stability.

Published: May 2023

Abstract
Transportation is one of the main sectors contributing to greenhouse gas (GHG) emissions that cause global climate change. One of the decarbonization strategies from the transportation sector that can be implemented is by switching to a sustainable mode of transportation, especially battery electric vehicles (BEV). Since mid-2021, Obi Island has been producing Mixed Hydroxide Precipitate (MHP). It is an intermediate product of limonite nickel ore processed using hydrometallurgical processing techniques through the first refining plant in Indonesia using High Pressure Acid Leaching (HPAL) technology. The MHP will be processed into Nickel Sulfate (NiSO4.6H2O) and Cobalt Sulfate (CoSO4.7H2O), the primary precursor materials for electric vehicles. The potential GHG emissions reduction in the transportation sector from the processing of limonite nickel ore in Obi Island is 2.04 MtCO2 in 2022 to 21.02 MtCO2 in 2040 with a total accumulation until 2040 of 344.56 MtCO2.

Abstract
This study aims to formulate an integrated and sustainable management strategy for Lake Limboto’s sustainable ecosystem. The stages of the study include (1) identifying the problems that occur in Lake Limboto and analyzing the general conditions of the ecosystem, which includes biophysical waters, land use patterns in water catchment areas, and socio-economics; (2) measuring the sustainability of the lake management using the Multi-Dimensional Scaling (MDS) method and leverage analysis. The results of the Multi-Dimensional Scaling analysis show that the sustainability index value of the ecosystem, economic, social, institutional, and technological dimensions are less sustainable, less than 50. In contrast, the economic dimension is entirely sustainable at 62.90; meanwhile, the ecosystem dimension index is 18.59, which means the sustainability status is poor. These figures indicate that the management of Lake Limboto and its surrounding area mainly considers the economic aspects and relatively ignores the dimensions of its ecosystem.

Abstract
Coastal aquifers are essential for coastal communities worldwide, one of which is in the Mandalika area (Lombok Island, Indonesia). This area is the tourism sector which requires an adequate supply of fresh water. Mandalika is a coastal area dominated by alluvial plains, an excellent rock as an aquifer. However, alluvial plains are also susceptible to seawater intrusion. This study uses a combination of gravity and geomagnetic methods to estimate bedrock potential as aquifers based on a 3D inversion model. Data collection was carried out at 151 measuring points using the loop method. Data processing was conducted using Oasis Montaj, Mag3D, and Grav3D. The data were combined to reduce ambiguity in interpreting rock-type estimates. The modelling results show that aquifer composition consists of sandstone, clay, and gravel with a density of about (1.3 - 2.4) g/cm3, susceptibility (0.00040 - 0.0045) SI at an average depth of 2 - 12 m with a percentage of 54.849% of the total 3D models. These rocks dominate the research location scattered around the coastal area of Kuta, around the Circuit to the Mertak area, and are concentrated in the flat morphology areas.
Mercury Reduction on Gold Extraction in Artisanal and Small-Scale Gold Mining. A Case Study in Pelangan Village, West Nusa Tenggara Province, Indonesia

Published: May 2023

Abstract
The most common method used for gold processing in artisanal and small-scale mining is amalgamation using mercury as a gold extracting agent. Indonesia is one of the countries that ratify the Minamata Convention, meaning that Indonesia has agreed to reduce or even eliminate the use of mercury. Some methods for replacing mercury as a gold-extracting agent are cyanidation and borax. The research aims to determine whether the miners in Pelangan still use mercury in gold processing. The method of this research is observation, interviews, and literature review. The data obtained were then analyzed descriptively. The result indicates that the miners in Pelangan Village use two methods of gold processing from ore: (1) amalgamation using mercury followed by cyanidation and (2) cyanidation. Most of the miners use the cyanidation method without going through amalgamation. The main reason they do not use mercury are amalgamation method yields low gold recovery and the price of mercury is high. This indirectly shows that the miners in Pelangan Village have contributed to efforts to reduce mercury use in Indonesia.

Published: May 2023

Abstract
Sedau Village is one of the villages in Narmada District, West Lombok Regency. Sedau Village is a tourist destination where the famous Mount Jae campsite is located. However, the environmental conditions of the area are still well-preserved. Around the tourist sites, there is a river flow containing a significant amount of sand and gravel, which the people in the area mine. Problems appeared as the West Lombok Government wanted to stop the sand mining while the Sedau Village Government supported it. This study aims to examine sand mining activities’ socio-economic and environmental impacts. The research methods used are field observation and direct interviews. Data were obtained from socio-economic and environmental sectors based on field observations and direct interviews with the miners and the local village community. The data is presented in the form of tabulated data. The study results indicate that the impact generated on the socio-economic and environmental aspects is positive, including an improvement in economic welfare, the condition of the river getting deeper, allowing it to accommodate larger volumes of water and preventing overflow during the rainy season.

Published: May 2023

Abstract
The production of cement results in a significant amount of energy consumption and CO2 emissions, which are major contributors to environmental pollution. Researchers have developed a ternary blended mix concrete to address these concerns by partially substituting cement with a combination of lime sludge (LS) and wollastonite powder (WP). This study investigated the mechanical properties (compressive strength, spilt tensile strength, and flexural strength) of a ternary blended concrete mix with a grade of M30. 180 specimens, including 60 cubes, 60 cylinders, and 60 prisms, were prepared for testing. The blended concrete mix was produced using different percentages of cement replacement by LS (5%, 10%, 15%) and WP (10%, 15%, 20%). The compressive strength for the ternary mix at 10% LS and 15% WP was 44.78% higher than the conventional mix, the flexural strength ternary mix at 10% LS and 15% WP was 25.46% higher than the conventional mix, and spilt tensile strength ternary mix at 10% LS, and 15% WP was 27.30% higher than the conventional mix at 28 days and trend is almost same for 7,56 and 90 days . The results showed that a ternary mix containing 75% cement, 10% LS, and 15% WP exhibited the best mechanical properties.
Gravity from transactions: fulfilling the entropic gravity program
Authors: Schlatter A , Kastner R E 
Published: May 2023

Abstract
This is a comprehensive review of new developments in entropic gravity in light of the Relativistic Transactional Interpretation (RTI). A transactional approach to spacetime events can give rise in a natural way to entropic gravity (in the way originally proposed by Eric Verlinde) while also overcoming extant objections to that research program. The theory also naturally gives rise to a Cosmological Constant and to Modified Newtonian Dynamics (MOND) and thus provides a physical explanation for the phenomena historically attributed to ‘dark energy’ and ‘dark matter’.

Abstract

Background
Locally infiltrating (T4) differentiated thyroid carcinomas (DTC) represent a challenge. Surgical strategy and adjuvant therapy should be planned balancing morbidity and oncologic outcome. A series of T4 DTC who underwent multidisciplinary evaluation and treatment is reported.

Methods
All DTC cases operated between 2009 and 2021 were reviewed and T4 DTC cases were identified. En bloc resection of inferior laryngeal nerve (ILN), tracheal (TR) and/or internal jugular vein (IJV) was performed in cases of massive infiltration. In case of pharyngoesophageal junction (PEJ) invasion shaving technique was always chosen.

Results
Among 4775 DTC cases, 60 (1.25%) were T4. ILN infiltration was documented in 45 cases (75% - en bloc resection in 9), TR infiltration in 14 (23.3% - tracheal resection in 2), PEJ invasion in 11 (18.3% - in 7 cases R0 resection, in 4 cases &lt;1cm residual tissue), and IJV resection in 6 (10%). Eleven post-operative ILN palsies, 23 cases with transient hypoparathyroidism and two hematomas requiring reoperation were registered. Final histology showed 7pN0, 22pN1a, 31pN1b tumors. Aggressive variants were observed in 78%. All patients underwent radioiodine treatment and 12 adjuvant external beam radiation therapy (EBRT). At a median follow-up of 47 months, no tumour-related death was registered. Seven patients required re-operation (DFS mean 123.7 months, CI:111.2-136.2).

Conclusion
Multidisciplinary approach is essential for the management of T4 DTC. Individualised and balanced surgical strategy and adjuvant treatments, in particular EBRT, ensure control of locally advanced disease with acceptable morbidity.

Abstract
A classical early sign of typical Alzheimer’s disease is memory decline, which has been linked to the aggregation of tau in the medial temporal lobe. Verbal delayed free recall and recognition tests have consistently probed useful to detect early memory decline, and there is substantial debate on how performance, particularly in recognition tests, is differentially affected through health and disease in older adults. Using in vivo PET-Braak staging, we investigated delayed recall and recognition memory dysfunction across the Alzheimer’s disease spectrum. Our cross-sectional study included 144 cognitively unimpaired elderly, 39 amyloid-β+ individuals with mild cognitive impairment and 29 amyloid-β+ Alzheimer’s disease patients from the Translational Biomarkers in Aging and Dementia cohort, who underwent [18F]MK6240 tau and [18F]AZD4694 amyloid PET imaging, structural MRI and memory assessments. We applied non-parametric comparisons, correlation analyses, regression models and voxel-wise analyses. In comparison with PET-Braak Stage 0, we found that reduced, but not clinically significant, delayed recall starts at PET-Braak Stage II (adjusted P &lt; 0.0015), and that recognition (adjusted P = 0.011) displayed a significant decline starting at PET-Braak Stage IV. While performance in both delayed recall and recognition related to tau in nearly the same cortical areas, further analyses showed that delayed recall rendered stronger associations in areas of early tau accumulation, whereas recognition displayed stronger correlations in mostly posterior neocortical regions. Our results support the notion that delayed recall and recognition deficits are predominantly associated with tau load in allocortical and neocortical areas, respectively. Overall, delayed recall seems to be more dependent on the integrity of anterior medial temporal lobe structures, while recognition appears to be more affected by tau accumulation in cortices beyond medial temporal regions.
