We prove an oracle inequality for the corresponding MSE in a general setting and derive the rates of convergence in different scenarios. By a careful analysis we show that no other a posteriori parameter choice rule can yield a better performance in terms of the order of the convergence rate of the MSE. In particular, our results reveal that the typical understanding of Lepskiĭ-type methods in inverse problems leading to a loss of a log factor is wrong. In addition, the empirical performance of SOLIT is examined in simulations.

The inversion parameter η could be controlled by varying the gallium (Ga) composition in the range 0.055 ⩽ η ⩽ 0.664. The composition-induced Néel-to-spin-glass (NSG) transition occurred between 0.05 ⩽ η ⩽ 0.08 and was verified by measurements of DC-AC susceptibilities χ and thermoremanent magnetization (TRM) below the Néel transition temperature T

Published: December 2023

Hydride vapor phase epitaxy (HVPE) is employed for the homoepitaxial development of AlN thick films on AlN substrates grown via physical vapor transport (PVT). A freestanding AlN substrate with a 200 μm thickness is then obtained by mechanically grinding away the PVT-AlN substrate. The as-grown HVPE AlN layer has a smooth surface with long parallel atomic steps. The freestanding HVPE-AlN substrate is crack-free and stress-free. In comparison to PVT-AlN substrate, HVPE-AlN substrate not only has better crystal quality but also substantially lower C, O, and Si impurity concentrations. The deep ultraviolet (DUV) transmittance of the 200 μm thick freestanding AlN substrate is as high as 66% at 265 nm. This performance aligns perfectly with the demands of AlGaN-based DUV optoelectronic devices.

Published: December 2023

The rapid urbanization in Jakarta has given rise to a wide range of urban problems, characterized by an imbalance between the population growth rate and urban resources. This imbalance has resulted in a decline in the quality of urban services, making the population highly venerable to diseases, particularly during and after the Covid-19 outbreak. Relevant studies have indicated that variables related to infrastructure, social and economic determinants can affect urban health. However, the literature exploring the relationship between health determinants and urban health from an urban planning perspective is still limited. The aim of the research is to examine the relationship between health determinants and urban health in Jakarta Province during the Covid-19 outbreak. The study employed Partial Least Square (PLS) path modeling using smartPLS software, while data were collected through questionnaires administered to 317 Jakarta residents. The results showed that urban health determinants, represented by the built environment/infrastructure and social determinants, significantly and positively impacted the physical health of Jakarta residents. However, the urban health determinants insignificant on the mental health of Jakarta residents during Covid-19. It was also found that built environment/infrastructure had a greater influence on physical health than other determinants. This impact was significant for both neighborhoods that are well-resourced and under-resourced. The influence of the social determinant on physical health significantly varied between these neighborhoods. This research emphasized the importance of stakeholders focusing on improving the population’s quality of life and health through the built environment/infrastructure and social determinants.

Published: December 2023

Providing public spaces within city-gated communities can help reduce social segregation between residents and non-residents. To facilitate interaction, it is important to identify the characteristics of public space that are most preferred. This study aims to identify the characteristics of public space based on the preferences of gated and non-gated residents in a private city-gated community. There are four characteristics of public space studied: multifunctionality, accessibility, convenience, and inclusiveness. Collecting data uses the questionnaire survey method. The analysis technique used second-order confirmatory factor analysis. This study’s results show that multifunctionality, accessibility, convenience, and inclusiveness are significant characteristics of public space to stimulate interaction between gated and non-gated residents in BSD City. Accessibility is the characteristic of mosques and markets. On city parks and a total public space, it is not proven. The users of city parks are not concerned with it as long as they can obtain their needs within it. So, the conclusion is that the three main characteristics of public spaces promoting interaction between residents of gated and non-gated are multifunctionality, convenience, and inclusiveness.

Published: December 2023

The JORR E1 (Cikunir-Jatiasih) toll road was was built with the primary goal of improving connectivity between the southern part of Bekasi City and neighboring regions. The construction and opening of the toll gate could yield a range of effects on the community, spanning from positive to negative impacts. This research aims to assess the impact of the Jatiasih toll gate’s operation on economic activities and their externalities based on public perception. Data were collected through questionnaires distributed to 102 residents of the Jatiasih and Jatimekar urban villages. A quantitative descriptive method with scoring analysis was employed for the analysis. The results indicated that the operation of the Jatiasih toll gate has significantly affected the economic condition of both the Jatiasih and Jatimekar urban villages. In the economic aspect, the operation of the toll gate has led to a considerable transformation of residential functions, with business activities being incorporated into residential properties. This integration has resulted in increased economic activities within a 1 km radius. However, it is important to note that the development of economic activities within this radius has generated negative externalities in the surrounding area. This research emphasizes the importance of monitoring economic activities to better understand economic situations and to facilitate policymaking geared toward sustainable development and management.

Published: December 2023

The Indonesian government has established a 30% reduction by 2030 target for reducing GHG emissions, through the 3R (Reduce, Reuse, Recycle) approach. In the City of Bandung, various institutions are involved in waste handling and reduction. The objectives of this study were to determine the GHG emissions, resulting from household waste disposal at Sarimukti Landfill, without (scenario 1) and with (scenario 2) the utilisation of Waste Banks, 3R Waste Treatment Facility (TPS 3R), and an incinerator in a TPS 3R, at Ciwastra Market, as well as to estimate the GHG emissions, once Bandung City successfully achieves its waste reduction and waste management target in 2025, as stated in the Bandung Mayor Regulation No. 1426 of 2018, leveraging all existing facilities with the landfilling (scenario 3) and incineration (scenario 4) method. The calculations made were aligned with the Intergovernmental Panel on Climate Change (IPCC) 2019 Guidelines Tier 1. The findings of this study revealed that, in the first scenario, the GHG emissions amount to 185,271.934 tons of CO2eq. In the second scenario, the emissions amount to 150,423.096 tons of CO2eq. Consequently, the reduction in GHG emissions achieved is 34,848.847 tons CO2eq. In the third scenario, the emissions are 64,373.560 tons of CO2eq, while in the fourth scenario, GHG emissions are 70,001.973 tons of CO2eq. These findings highlight the substantial GHG emission reductions achievable through the implementation of waste management strategies. By adopting these approaches, it is possible to mitigate the environmental impact of waste disposal and contribute to the reduction of GHG emissions, well in tandem with the climate change mitigation goals.

Published: December 2023

The concept of walkability is about the provision of a pedestrian-friendly environmental condition that provides security, comfort and safety, and offers visuals for pedestrians. The Bandung City Square Area has various attractions which all promote walking activities. However, the presence of street vendors, the lack of facilities for the disabled, inadequate vegetation, crossings, and supporting facilities, and also illegal parking have caused problems, which have rendered the pedestrian-friendly environmental aspects not being able to be fulfilled. This study aims to assess the walkability of streets in Bandung City Square Area, using aspect of walkability based on pedestrian perception as users. The research was conducted using the Global Walkability Index and Multicriteria Satisfaction Analysis, based on pedestrian perception surveys. The results showed that, the existing conditions of streets’ walkability in Bandung City Square Area is Waiting to Walk, which is adequate for walking. For example, five parameters, namely the availability of crossings, security against crime, disabled infrastructure, grade safety of crossing, and motorist behavior were found to be below average. It can also be concluded that, three parameters, namely crossing safety, security against crime, and disabled infrastructure require immediate attentions. The overall results of the study suggested that, improvement of streets’ walkability is needed by focusing on parameters that are below-average, thus requiring immediate attentions. Further research is recommended to find effective improvements for streets’ walkability, based on the pedestrian perception to have a pedestrian-friendly environment in Bandung City Square Area.

Heavy metal contributed in bio-magnification process. So, its presence needs to be monitored and evaluated to prevent and control its hazards to human health and sustainability river ecosystem. One of that heavy metal is lead. This study aims to assessment the lead metal pollution in Ciliwung River because one of its uses is as water resources for Regional Drinking Water Company (PDAM). This study used a survey and analytical method. There were 12 samples of water column and 10 samples of sediments that distributed from upstream to the beginning of downstream. The parameters determined in site used water checker included temperature, pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Dissolved Oxygen (DO), and Oxidation Reduction Potential (ORP). While the lead contained in sample used Automatic Absorption Spectrophotometric (AAS). The result showed that lead content in all samples exceeded the quality standards and the lead on sediment were more than in water column. Lead in the Ciliwung River is mostly due to anthropogenic sources because it occurred naturally in small amounts. Downstream, the EC, TDS, and ORP values increase, while the pH and DO value decreases. The ORP values at all sampling points were positive. It means that deoxygenation occurred along the Ciliwung River. The implication is needed the additional raw water processing that accompanied further economic analysis to make sure the water availability for the community sustained.

Published: December 2023

The Cipunagara River Basin is a component of the Citarum Watershed, necessitating a thorough analysis of hydrological data particularly rainfall and discharge for effective management. The watershed spans a moderate area of 1,363 km2 across three administrative divisions: Subang Regency, Indramayu Regency, and a segment of Sumedang Regency. Hydrological data analysis is imperative in watershed management. This study aims to analyze the key hydrological elements relevant to Cipunagara Watershed management. Rigorous consistency and homogeneity tests were conducted on rainfall data from each station. Changes in watershed flow patterns were scrutinized by examining shifts in runoff coefficient values and base flow magnitudes. The upward trend in runoff during the rainy season and the corresponding decline in base flow throughout the dry season may be attributed to land use alterations within the Cipunagara Watershed zone. To proactively address drought concerns in watershed management, the study calculated the 80% dependable flow to assess water availability during arid months, yielding an 80% dependable flow rate of 16.25 m3/s for the Cipunagara Watershed.

Authors: Adirianto B , Bachtiar T
Published: December 2023

The diversity, structure, and behavior of soil microbes communities, which are crucial to the breakdown of organic matter, cycling of nutrients, and general health of the soil, can be impacted by biochar. This study uses a meta-analysis approach to examine how biochar affects soil microbial diversity, and it anticipates that the results will take the form of a summary of the information that has already been published in journals. This study presents a meta-analysis of 24 articles published between 2018 and 2023 that reported biochar’s effect on soil microbial diversity and richness. Alpha diversity indexes such as Shannon, Simpson (Diversity index), Chao1, and ACE (Richness Index) were measured as parameters, as well as the operational taxonomic units (OTUs) count. The levels of biochar dosage varied from 0 to 50% w/w. Simpson (0.546), the OTUs (0.473), Chao1 (0.227), Shannon (0.125), and ACE (0.056) had the most significant effect sizes for the biochar (Hedges’d), with the majority of the values impact sizes being on the right. According to aggregate-driven tree analysis, the type of biochar, application rate, use of the soil, and length of the experiment all play a significant role in how biochar affects soil microbial diversity. In conclusion, adding biochar requires considering biochar application rates and type to improve microbes’ diversity.

Authors: Gunarti A S S , Zaika Y , Munawir A , Suryo E A , Harimurti
Published: December 2023

The behavior of expansive soil, which is sensitive to water, makes it susceptible to moisture content changes, resulting in the soil becoming soft during the rainy season and soil shrinkage during the dry season. This research aims to study the effects of the wet-dry cycle on the bearing capacity and swelling potential of stabilized expansive clay soil using two types of industrial waste, namely Fly Ash (FA) and Waste Foundry Sand (WFS), as soil improvement and industrial waste management efforts. The wet-dry cycle is assumed to represent the changes in the environment due to seasonal variations. The wetting cycle is conducted by immersing the soil samples in water, while the drying cycle is achieved by allowing them to air dry at room temperature. The FA content is set at 9% and the WFS content at 15% by weight of dry soil. The California Bearing Ratio (CBR) test is performed after the completion of the wet-dry cycle, while the swelling test is conducted during the wet-dry cycle. Each sample undergoes one, two, and three cycles of wetting and drying. The results showed that the CBR value increased with the addition of FA and WFS. The CBR value of natural soil is 8.89% while the CBR value of soil+9%FA+15%WFS is 16.02%. During the wetting phase, the CBR value decreases with increasing moisture content. After undergoing the third cycle, the CBR value and development potential tend to remain constant.

Authors: Irfani M R A N
Published: December 2023

The increasing demand for clean water in urban areas calls for innovative and sustainable water treatment solutions. Capacitive deionization (CDI), using fungal-based materials for desalination, offers potential benefits such as sustainability, low cost, and scalability, for urban water provision. However, few studies have explored the practical application of fungal-based CDI technology. This research assesses the feasibility of implementing fungal-based CDI technology in urban water provision systems, drawing on the key study from Chen et al.’s 2022 research, examining the preparation and performance of fungal-based CDI electrodes derived from Aspergillus niger. To create a reliable and up-to-date conceptual model, additional literature from indexed journals, focusing on CDI in desalination facilities from the past decade, is also reviewed. A conceptual framework was developed to demonstrate the potential integration of fungal-based CDI technology into urban water treatment systems, and taking into account factors such as capital and operational costs, scalability, and sustainability. The outcome of this study is a conceptual model that promotes further development of urban water provision through desalination, broadening the perspective on the application of emerging biotechnology, using fungal-based materials for water provision.
Municipal solid waste management in regency area in Indonesia: a review of Deli Serdang

Published: December 2023

Municipal solid waste management (MSWM) in Indonesia is increasingly complex for various reasons. The quantity of solid waste is expected to increase substantially due to an increasing population and rapid urbanization. Each municipality in Indonesia has a distinct technique and method to manage solid waste, depending on the peculiarities and problems. Cities and regencies have different characteristics. Research on municipal solid waste management conducted in regency areas is still limited. This study aims to investigate the implementation of MSWM in Indonesian regency areas. This study is based on a literature review and the relevant policies, but it also incorporates simple statistical analysis to support the points and arguments in this paper. The review found differences characteristic of MSWM in regency areas and city areas, such as waste generation, waste composition, and source of waste. MSWM solutions vary according to each municipality and rely heavily on local governments’ commitment and their financial, technical, and institutional capacity. The existing waste problem must be addressed holistically from upstream to downstream with a ‘cradle-to-grave’ mindset to create tangible advances in Indonesia’s solid waste management.

Published: December 2023

In 2020, 21 regencies/cities (out of 35 regions) in Central Java will hold regional head elections. One of the consequences will be the preparation of the Regional Medium Term Development Plan (RPJMD) for the 2021-2026 period. The RPJMD was compiled during the Covid-19 pandemic, as well as the strengthening of other global issues such as the industrial revolution 4.0, society 5.0, advances in information technology, disruption and vulnerability to global economic crises, and food and energy issues. This research focuses on formulating strategic issues in the RPJMD document for the 21 regions to understand the framework, formulation process, and priority of strategic issues. This research is a descriptive study through a qualitative approach and is applied with practical purposes using desk study techniques. The research subjects were the RPJMD documents of 21 selected regencies/cities, especially in regional strategic issues. Data processing is done by classification technique, and data analysis is done by content analysis technique. The study results show that the strategic issues of concern are general, almost the same as the previous planning documents, such as bureaucratic reform, human resource capacity building, poverty (and unemployment), infrastructure, economic growth, and environmental natural resources. Some regions also place popular actual issues such as the Covd-19 pandemic and its recovery, the industrial revolution, smart cities, and SDGs, and only a small number of regions raise specific issues such as investment, village development, innovation, information technology, or sectoral issues such as agriculture, tourism, creative industries. This study concludes that the process of formulating strategic issues is still normative procedural, and general in nature, with a dominant technocratic approach, and needs to accommodate actual local issues and community discourse or aspirations. Formulating strategic issues also has no relation to regional development issues, more accommodating global, national issues and other planning documents without in-depth analysis.

Spatial planning for agricultural land use is required since the region with its land resource has an opportunity to be opened and cultivated. On the other side, balanced environment should be maintained in order to achieve sustainability for future use. Land resources information can then be used as basic information and prerequisite for analysis and evaluation in planning process. Because of the lack of data, this study was conducted to generate and provide land resource information. Landform approach using raster surface analysis and slope classification derived from digital elevation model (DEM) was then used to determine agricultural land regions. Procedure of land suitability evaluation in addition to geographic information system (GIS) technology were applied to define specific kind of use for lands. In the case of East Barito as study areas, mainly on the basis of landform analysis, the region can be classified into 6 slope classes i.e. <3%; 3-8%; 9-15%; 16-25%; 26-40%; dan >40%. The result of land suitability evaluation integrated into GIS environment establish that arable lands is still available with total area of 226,211 hectare (59.11%) of total study areas. Furthermore, the region can then be delineated for group of commodities involving food crops, estate crops, and forest as well with each total area 62,291 hectares (17.96%), 183,107 hectares (52.78%) and 101,513 hectares (29.26%), respectively. Several restrictive factors that should be considered include slopping lands and peat depth. Any appropriate and specific programs for agricultural development can then be formulated in land use planning process.

Land footprint: theory, methodology, and applied ecological-economic principles in Ukraine
Authors: Skrypchuk P , Suduk O , Shpak H , Skrypchuk M
Published: December 2023

This article justifies methodological approaches to determine the land footprint using scientific research on ecological, water, and carbon footprints. Foreign scholars define the land footprint as the amount of land used to produce goods until the products are finally consumed in another country or region. This means that the system can account for the relocation of production to other parts of the world. In Ukraine, several indicators have been proposed to assess the ecological consequences of agricultural land use. They allow for monitoring, control, and prediction of changes in land, identifying crisis situations in agricultural land use. In our opinion, them should be use to characterize the «land footprint». The article analyzes the ecological consequences of the reorientation of Ukrainian producers exclusively on the market demand of grain crops for the purpose of export. It establishes that in adapting agricultural production to market conditions in Ukraine, a new land use system has formed, which benefits large landowners, preference is given to market-driven grain and technical crops, an increased burden on land resources, their depletion is occurring, and negative values of the «land footprint» are observed from such land use.

The vegetation in the landfills within the Western Forest Steppe of Ukraine is characterized by the rich species composition of the grass cover near the bottom and its almost absence at the top (southern slope). The transforming function of adapted plant groups leads to significant reduce of the intensity of denudation processes of technogenic substrates, and initiate soil-forming processes in them. The aim of the work is to establish the peculiarities of successional processes in different types of landfills of the Western Forest Steppe of Ukraine, depending on various technogenic factors. It was found that large landfills have the largest species composition – Lviv – 30 species, Ternopil – 20, Lutsk – 19. Small landfills – Lavrykiv – 10 species, Vereshchytsya – 11 species have the smallest species composition. Succession stages (syngenetic, initial endo-ecogenetic, mature endo-ecogenetic) are described at each investigated landfill, and projective coverage is calculated. It was established that the highest coefficients of Jaccard’s floristic similarity are characteristic to the investigated areas of landfills where there is no waste dumping, or it is only in certain areas (the second phase of dumping). The average coefficient of floristic similarity of all investigated landfills isKj=0.29.

The article presents methodological and applied principles for justifying the feasibility of introducing modern membrane technologies of deep processing of milk whey into the practice of Ukrainian milk processing enterprises. It has been identified that the most common way of processing milk whey both in Ukraine and in global practice is its drying. As an alternative to the traditional technology of drying milk whey, it is proposed to introduce into the practice of Ukrainian milk processing enterprises an innovative technology of its deep processing, which includes the fractionation of whey proteins and the release of lactose derivatives, which is important for the use of processing products as innovative functional food products. The expediency of introducing modern membrane technologies of whey processing at domestic milk processing enterprises is substantiated, which allows rational use of raw milk resources, reducing the negative impact on the environment, and increasing the profitability of production. The results of calculations of the total ecological and economic effect are presented, which prove that the effect of the introduction of modern membrane technologies of deep processing of milk raw materials significantly exceeds the effect of using the traditional technology of drying milk whey, which is widely used in domestic milk processing enterprises. It was found that the ecological effect is manifested in the reduction of volumes of liquid industrial waste and fines for violations of environmental legislation and can be considered as an alternative to the construction of own treatment facilities. The economic effect is achieved by expanding the product range of exports and the offer on the world markets of high-margin dairy products for narrow target groups of consumers.

Non-timber forest goods (NTFPs) refer to the various goods obtained from plants and animals inside forest ecosystems, which possess tangible values that are often not accounted for in a nation’s fiscal records. Throughout the course of human history, these items have been utilized for a diverse range of reasons, including but not limited to sustenance, animal feed, textile production, traditional medicine, agricultural resources, household goods, construction materials, and similar applications. These products are often intertwined with several traditional beliefs and cultural practices. The current investigation was conducted in three districts within the Himachal Pradesh region of northern India, with the aim of comprehending the significance of Non-Timber Forest Products (NTFPs) in the everyday livelihoods of rural communities residing in the Himalayan area. A total of 700 participants were surveyed using a prepared questionnaire.

Modern agricultural production is under the direct influence of climatic changes, which is also reflected in the water regime formation of the soil during the cultivation of crops. Calculations were made and graphical materials were created for average daily, average decadal, and average monthly values of temperatures and the amount of precipitation per day, month, and year. The influence of modern climatic factors on the water regime formation of the soil (according to the data of the weather station of the city of Kovel, Volyn region) over the last 11-year period has been established. It was determined that the distribution of precipitation is as follows: the share of light precipitation (< 3 mm) is on average 13.9%, moderate (4–14 mm) is 43.3%, significant (15–49 mm) is 36.4%, strong (50–79 mm) is 5.4%, and extraordinary (80–100 mm) is 1% of the total amount. It was determined that the active layer of the soil is formed due to the influence of moderate and significant precipitation. Informational materials on the distribution of atmospheric precipitation by year in quantitative and percentage indicators and their repeatability are presented in an interactive visual report with graphic materials (dashboard), which allows the processing of large arrays of data. It was determined that modern climatic changes (increased air temperature, uneven distribution, change in the nature, intensity, and structure of precipitation, and the increase in the number of cases of heavy downpours that are local in the warm period of the year) don’t allow for the effective accumulation of moisture in the active soil layer. The obtained information materials are the basis for developing a methodology for substantiating the parameters of the management of the soil-water regime on reclaimed lands, taking into account the peculiarities of its formation in modern economic conditions and climate changes.

The relationships between the ecological footprint indicator and the level of achievement of sustainable development goals at the global level were examined. Cluster analysis tools were used to assess such relationships by grouping countries with similar characteristics according to these two indicators. As a consequence, four clusters of countries were identified. The first cluster, which mainly includes African countries, is characterized by a low level of economic development and a minimal impact on the environment. It was determined that the second cluster includes many countries of the European Union, Argentina, Brazil, Cuba and Chile and it’s characterized by a high level of achievement of sustainable development goals and a moderate impact on nature. The third cluster, which includes India, Egypt, Indonesia and other countries, has a low ecological footprint, indicating conservation of natural resources and an average level of achievement of sustainable development goals. These countries have the potential for harmonious social, ecological and economic development. It was established that the countries of the fourth cluster have achieved a significant level of sustainable development, but they use large amounts of natural resources. It was found that the common directions of environmental policy for SDG achievement of are the fight against pollution, resource exhaustion and climate change to avoid a decrease in quality of of life of citizens.
