Production of Alkaline and Acidic Water by Electrolysis Solar Energy Source

Background: Alkaline and acidic water can be produced through the electrolysis process. There are two types of electrolysis equipment, namely batch type and continuous type, that can produce it. Continuous type tools are fast but expensive. Batch type tools are cheaper, but the process is slow. Both types of equipment require large amounts of energy and are expensive to operate. Another problem is that the content of the ions that form alkaline and acidic water is not yet known. Objective:The Objective is to determine the changes in ions that occur on the anode and cathode sides, to investigate the types of ions that most influence the formation of alkaline and acidic water, and to create a piper diagram. The aim of this research is to create a device that can produce alkaline and acidic water at a price that is affordable for the wider community. Method: This equipment is made from a portable plastic teapot as the cathode side and a small bottle as the anode side. The anode and cathode sides are separated by a cellulose cotton membrane, with carbon and stainless steel (SS) electrodes. The electric voltage taken from a solar cell module is 12 V;50 Wp. The output voltage of electrolysis was converted to 45 VDC in one hour. Electrolyzed water with an initial pH of 6.71 was taken from the Regional Drinking Water Company (PDAM) of Bandung City, Indonesia. Testing for the content of ions in water using American Public Health Association (APHA) standards was carried out in the laboratory of the ITB-Bandung Environmental Engineering department. Results and Conclusions: Based on the test on the sample, it was determined that the formation of alkaline water at the cathode side with pH 8.32 is caused by the ions Ca2+, Na+, Mg2+, and K+, with a concentration of 0.387; 0.369; 0.302; and 0.284 mmol/L, respectively. Some of the Mg2+ ions were precipitated. The formation of acidic water at the anode side with pH 2.34 was caused by the anions Cl-, NO3- , SO42-, and CO32-/HCO3 with a concentration of 1,757; 0.052; 0.147, and 3.153 mmol/L, respectively. Furthermore, it is concluded that the electrolysis device is designed for the production of alkaline and acid water at a capacity of 1400 mL in 60 minutes, with an average energy of 0.002 kWh and a cost of unit production of around Rp. 2.8. Research Implications: Useful for the development of education, teaching, and further research, especially in electrochemical major, as well as community service in making alkaline and acidic water for health. Originality/Value: Practical, simple, cheap way to make alkaline and acid water, qualitative and quantitative analysis, ion composition before and after electrolysis reaction, use of solar energy for electrolysis, changes in piper diagram before and after electrolysis.

Redevelopment of the Urban Area of the Former Canossian Oratory within the City Walls of Feltre

This paper concerns the redevelopment of an urban space within the historic walls of Feltre, an ancient city located inthe province of Belluno, not far from Venice. It is particularly focused on the disused Oratory of the Canossian Friars,at the top of the medieval city. The site is now abandoned and degraded, devoid of function and unresolved in form.It is located close to the city's main square and is bordered by pre-existing buildings of relevant historical importance,including the Castle, the Napoleonic Stables, the Clock Tower, the Civic Museum and the Church of San Rocco. In another respect, the former Oratory of the Canossian Friars, which was investigated by our research group at the Department of Civil, Environmental and Architectural Engineering of the University of Padova, is proposed as a case study regarding the relationship between new and old.

The International Conference on Environmental and Earth Sciences

“Multidisciplinary Approach in the Environmental and Earth Sciences for Sustainable Development” ICEES 2023 (https://www.its.ac.id/tlingkungan/icees2023/) INTRODUCTION Institut Teknologi Sepuluh Nopember (ITS) celebrates its 63rd Anniversary on November 10th, 2023. To commemorate this moment, the Department of Environmental Engineering (DEE), Faculty of Civil, Planning, and Geo-Engineering (CIVPLAN) at ITS, in collaboration with the Department of Geophysics Engineering of ITS and the Faculty of Engineering and Built Environment of Universiti Kebangsaan Malaysia (UKM), conducted the International Conference on Environmental and Earth Sciences (ICEES). ICEES 2023 took place in conjunction with the CIVPLAN’s International Conference, which serves as a platform to connect with other seminars held by each department within the faculty. Environmental issues have been increasing as a result of many factors that lead to potential detrimental effects on our children’s future. For the past 40 years, DEE has been spending tremendous efforts to contribute ways to reduce and minimize environmental pollution.This conference takes the general theme of the Multidisciplinary Approach in the Environmental and Earth Sciences for Sustainable Development, supporting the implementation of Sustainable Development Goals (SDGs). Rapid population growth and economic development have become contributing factors to environmental degradation. Urban areas receive more pressure due to escalated urbanization, excess use of natural resources, and pollution of the environment. Environmental pollution has been linked to various diseases, such as water-borne diseases and respiratory diseases, and the endangerment of biodiversity. Over the past decades, cities in Asia have been rapidly growing. Climate change has exacerbated the deterioration in environmental quality in the cities. Communities living in small islands and coastal areas became more vulnerable than before.More efforts are needed to develop solutions to create sustainable cities and communities. ICEES 2023 emphasizes multidisciplinary research in environmental and earth sciences for sustainable development along with practices and fosters exchanges among scientists, practitioners, professionals, and young researchers who are concerned with the above aspects. DEE strives to contribute not only to society but also to knowledge updates.List of Objective, Conference Date and Platform, Participants, Acknowledgements, Sessions, Organizers, Contact person, Administration, Secretariat, Documentation, International Advisory Board, Scientific Committee are available in this Pdf.

Conversion of Rice Straw to Biochar Through Microwave Pyrolysis for its Use as Partial Replacement of Cement

Background: An experimental study was conducted to explore the feasibility of partially substituting biochar in cement, for making concrete mixture in civil infrastructures. The biochar was derived from the pyrolysis process in thermo-chemical conversion of the most under-utilized agricultural residue i.e. rice straw. Demand of cement is increasing day by day due to fast growth of construction sector all around the world. The current scenario of rampant on-farm burning of rice straw is a great concern not only for maintaining the fertility aspects of the cultivating land but also for the degradation of surrounding environment. Production of cement is equally very energy intensive and contributes a lot in emitting greenhouse gases, mostly carbon dioxide to the environment. An attempt was therefore made in the present study to partially replace the rice straw biochar with cement to reduce the production of the later and to evaluate the key performance parameters of biochar based concrete. Methods: The study was carried out in the Department of Agricultural Structures, Civil and Environmental Engineering, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, India during 2021-22. Microwave assisted pyrolysis was followed for quick and efficient heating of the biomass feedstock. Efforts was also made to supply power to the microwave pyrolyser from a reliable source of power i.e. solar photovoltaic system for its popularization even in remote and off-grid rural areas. Result: The yield of biochar was found to be higher (about 28%) at 600 W input power to the microwave reactor and 15 minutes’ reaction time in the pyrolysis process of rice straw. The performance parameters of biochar based concrete such as initial setting times, final setting times and workability were found to be decreased by 8, 5 and 9% respectively and compressive, split tensile and flexural strengths were increased by 13, 18 and 5% respectively compared to the reference concrete. Biochar from rice straw can hence ultimately be utilized as partial replacement of cement for use in construction industry.

Design, Validation and CFD Modeling of an Environmental Wind Tunnel

The wind erosion of granular materials stored within the open yards of industrial plants (i.e., industrial wind erosion) and the subsequent emission and dispersion of particulate matter (PM) in the surrounding areas represent an important issue for the exposed population and for the environment as a whole. The Environment Impact Assessment (EIA) and the design of emission control measures require a deep knowledge of the erosion phenomenon, and the precise estimation of the Emission Factors (EF) associated with the specific PM source under investigation. Aiming to characterize the emission potential of industrial granular materials, a new Environmental Wind Tunnel (EWT) has recently been built at the Department of Civil and Environmental Engineering and Architecture (DICAAR) laboratories, in Cagliari University. The article discusses the EWT’s updated design and the set-up methodologies applied to reproduce the Atmospheric Boundary Layer (ABL) acting over the surfaces of coarse and heterogeneous granular materials. In addition, a Computational Fluid Dynamics (CFD) model of the EWT has been developed to reproduce and analyze the wind field throughout the entire tunnel volume and preliminarily evaluate possible modifications to the original design. The accuracy of the simulation has been verified by comparing the CFD model and the results of the experimental tests.

Development of lightweight building blocks using expanded polystyrene

This study aimed to develop lightweight building blocks using Expanded Polystyrene (EPS) with varying percentages, assess their properties, including density, water absorption, porosity, and compressive strength, and evaluate the unit cost of the blocks. The heat-passing rate of the blocks was also investigated. EPS blocks were produced at the Concrete and Materials Testing Laboratory in the Farm Structure and Environmental Engineering Department, Bangladesh Agricultural University, Mymensingh. Local sand and ordinary Portland cement were utilized, with the EPS bead sizes ranging from 2.36mm to 6.35mm. Five different percentages of EPS beads (0%, 5%, 10%, 15%, and 20%) were selected for each block, and the cement-to-sand ratio was 1:4. A total of 75 EPS blocks were fabricated and cured in water for 28 days. The results showed that the density was highest for 0% EPS blocks (2139.75 kg/m3) and lowest for 20% EPS blocks (1699.08 kg/m3). Water absorption was most insufficient for 0% EPS blocks (4.39%) and highest for 20% EPS blocks (9.07%). The porosity was highest for 20% EPS blocks (14.37%) and lowest for 0% EPS blocks (6.74%). The heat passing rate was minimal for 0% EPS blocks and highest for 20% EPS blocks. Compressive strength was highest for 0% EPS blocks (13.37 MPa), moderate for 10% EPS blocks (10.87 MPa), and lowest for 20% EPS blocks (8.94 MPa). The unit cost of 100 blocks was highest for 0% EPS blocks (15.18 USD) and lowest for 20% EPS blocks (13.28 USD). Overall, the EPS blocks are recommended for construction due to their durability and compressive strength.

Detection and quantification of wave trends in the Mediterranean basin

A study of a 42-year (1979–2020) long wave time series was performed for the Mediterranean Sea to detect and quantify trends in two relevant wave parameters adopted for coastal and offshore engineering purposes: significant wave height, Hs and peak period, Tp. The high resolution MeteOcean Re-Analysis database by the Department of Civil, Chemical and Environmental Engineering (DICCA) was used. At yearly and seasonal scales, the trends of the mean and maximum values were detected by the Mann–Kendall test, choosing a significance level equal to 90%. The slope or increase/decrease trends in Hs and Tp were assessed by the Theil–Sen estimator. For the mean values of Hs and Tp, increasing trends were detected for the Libyan, Levantine and Aegean seas, while for the maximum values this increasing trend was observed in a large part of the Mediterranean Sea. Finally, for the different marginal seas of the Mediterranean basin, a running trend analysis was applied in order to quantify the effect of the time window in the trend detection. The obtained results can be significant for flooding and erosion control strategies, ship and port operations, design and verification of structures, installations of Wave Energy Converters, in a hot spot for climate change such as the Mediterranean basin.

Social imaginaries methods and socio-engineering competences in sustainable river management (a case study in the living lab Upper Citarum)

The Living Lab approach has become popular and developed in the past decade. It could provide a configuration to pursue a shared vision of integrated water resources management of the Citarum River in West Java - Indonesia. The multi-stakeholder situation and the growing recognition of interdependencies among stakeholders foster the complexity of addressing sustainable river management for the Upper Citarum River. To gain insights on essential competencies and adaptations in higher education curricula, the Environmental Engineering Department of the Faculty of Civil and Environmental Engineering-ITB, Telkom University Indonesia, and Van Hall Larenstein University of Applied Sciences, Netherlands, joined hands in a collaborative research project. This study aims to develop a socio-engineering aspect for sustainable river water quality management in the Environmental Engineering Field and Curricula. The methods used are social imaginaries of Participatory Mapping and a Poetry Route that allowed the involved river bank communities to activate their role and take positions in the living lab. Institutional stakeholders, acting in a facilitating role, learned to gain and share information from and with the community. The result concludes that social imaginaries methods enable a new perspective in developing community-based programs and advocate further exploring the socio-engineering competencies of environmental professionals.

Editorial to the Special Theme Sustainability

Sustainability represents a commonly agreed global development goal. It aims at ensuring the quality of life on Earth for current and future generations. Sustainability should thus become the fundamental overarching concept for the efficient/high-quality design and operation of any product or service throughout its lifecycle—focusing on all three pillars of sustainability—social, environmental, and economic. Among the different socioeconomic sectors, dealing with the impacts that the construction sector has is fundamental, as it strongly contributes to many of the pressing issues that need to be addressed. Not only do we need to improve the economic, environmental, and social performance of our built environment, but we also need to be better prepared for new conditions that are appearing as a cause of global challenges (e.g., climate change). The importance of this approach is all the more clear in light of an increasing number of man-made and natural disasters occurring globally. Thus, current developments and changes in the environment and socioeconomic situation require improvements in the technology of different processes that are involved in construction projects. In this context, concrete is a particularly interesting material, because it has a great potential for new technical solutions meeting new requirements, leading to the necessary reduction of environmental impacts and at the same time improvement of social and economic conditions, including safety and reliability during emergency situations. However, considering the huge volume of global concrete production and the negative impacts closely linked to its production, the overall environmental negative impact associated with the construction of concrete structures on a global scale is considerable. In view of the above global situation, it is of utmost importance to focus on the introduction of new production and construction technologies, advanced design techniques and efficient operation, maintenance, and recycling techniques of concrete structures. Concrete mixes, concrete products, and concrete structures should be designed to meet the requirements of sustainability—namely, to minimize their negative impacts and increase the positive impact on society, the environment, and the economy. This could be achieved by increasing the quality and durability of concrete structures throughout their life cycle, through (i) improvements in design methods, (ii) development of concrete mixtures, composite materials, and reinforcement methods, (iii) modernization of concrete technology, (iv) development of integrated design approaches, and (v) innovation in maintenance, repair, demolition, and recycling processes. This requires the involvement of all actors in the construction process, from material manufacturers, designers, and builders to users, and their conviction and initiative in the need to achieve better results in terms of sustainability requirements. This special theme of Structural Concrete journal: Sustainability of Concrete Structures collects a selection of contributions related to different aspects of sustainability showing potential of concrete structures to contribute to the achievement of the Sustainable Development Goals (SDGs) set by the United Nations in 2015 as an action plan until 2030. The content of this special theme volume covers issues related to Life Cycle Assessment of concrete structures, carbon neutrality, use of recycled concrete and other recycled components, optimization of concrete structures, and many other issues bringing the contribution of concrete research and development to SDGs. We trust that the presented selection of articles is of interest to the concrete community focusing on the development of concrete structures toward a sustainable and resilient built environment as a contribution for future generations.
