Manure as a source of energy and heat-insulating material in the cold climate of Yakutia
Authors: Ushnitsky I N 
Published: March 2022

Abstract
Energy is essential for the development of human society. Biogas plants, as a part of an integrated product-to-energy system, are an alternative to the use of waste biomass as raw materials due to their energy production capacity and thermal insulation material. Animal waste is an important resource that is used to replenish organic matter and improve soil conditions. Depending on the weight, cattle produce approximately 4 to 6 tons of fresh manure per year. With the constantly increasing prices for fossil energy resources, as well as the depletion of oil and gas reserves, an increasing number of countries are developing alternative energy sources. One of these types is biogas. It is necessary to note that the main disadvantage of biogas energy is the significant weight of specific capital costs and low profitability of projects. Despite this, in Russia there is the increase in demand for biogas units (BGU), both for small consumers (with a digester volume of 3-20 m3) and for medium-sized consumers (with a digester volume of 30-100 m3). The point is that biogas technologies properly fit into the UN Doctrine of sustainable development of society. Many in Russia are committed to this idea. They are guided by the principle “Reason is a clumsy instrument of a scientist; intuition is the unmistakable leader of the seer” and try to solve this problem each in his own way. According to UN experts, this very integrated approach, when a scheme for the selection of enterprises and industries operating on one type of raw material is carried out, and waste and byproducts of one production act as raw materials or semi-finished products for another type, can completely solve the problem of sustainable development of society.

Evaluation of the effect of microwave heating modes on the germination ability of lupine seeds
Authors: Vendin S V 
Published: March 2022

Abstract
Technologies based on the use of the energy of electric, magnetic and electromagnetic fields can be successfully applied in agricultural production. According to the available research results, it can be quite reliably asserted that during the pre-sowing treatment of agricultural seeds, it is possible to use microwave electromagnetic fields. A feature of such technologies is the experimental determination of the parameters of microwave exposure. The materials of the article contain the results of experimental studies to assess the temperature effect of microwave energy on the germination ability of lupine seeds. Regression equations are obtained in coded and natural variables to assess the effect of the final temperature and microwave heating rate on the germination ability of lupine seeds. Analysis of the results obtained indicates that the final result of microwave seed treatment depends on each factor separately and on their relationship. In addition, it is necessary to strictly observe the processing regimes, since the seeds are sensitive to energy effects and, in addition to the stimulation effect, you can get a negative result or get into the zone of insensitivity. According to the data obtained, the best result of microwave stimulation of lupine seeds is observed when the seeds are heated to 50 °C at a heating rate of 0.46 °C/s. Compared to the results of wheat seed treatment, higher final temperatures and microwave heating rates are required to stimulate lupine seeds. In addition, for a positive result of processing, it is necessary to take into account that the microwave heating rate of the seeds determines the final temperature of their heating. To stimulate lupine seeds, it is possible to recommend microwave heating to 50-51 °C at a microwave heating rate of 0.46-0.47 °C/s.

Published: March 2022

Abstract
The analysis of productivity studies of spring oilseeds of the Brassicaceae family during their cultivation on gray forest soil in the crop rotation link in Ryazan region, Russia is proposed. The influence of variants of the main tillage on the yield of spring rape variety Ratnik and spring rape variety Lipchanka has been studied. The experiments were carried out in 2015-2020 on dark gray forest soils. Agrotechnical measures for the cultivation of spring oilseeds are typical for the Non-Black Earth Zone of Russia, which includes Ryazan region. On average, according to the research results, the highest yield in spring rape was recorded on the variant of the fallow link of the crop rotation + moldboard processing (3.13 t/ha), in the spring rape (2.56 t/ha). When determining the biological activity of the soil, the method of linen with a density of 150 g/m2 was used. In the experiment, on the variant with the moldboard method, when using a reversible plow, the degree of decomposition of the linen was the greatest in the experiment. In agrocenoses of agricultural crops, a pattern was noted for an increase in biological soil activity, in rape the degree of decomposition was recorded in 45.3 % and in spring coleseed it was 41.9 %.

Published: March 2022

Abstract
Transportation sector in Southeast Asia is highly dependent on petroleum products, making it one of the most carbon-intensive energy sectors in the region. The 6th ASEAN Energy Outlook (AEO6) projected the sector’s oil consumption to rapidly grow to 330 million ton of oil equivalent (Mtoe) by 2040 or about 97% from total energy consumed in the sector. Mostly imported, the ever-increasing oil demand poses risk to economic and energy security. The growing concern of climate change also brings another issue to the sector. Cleaner mobility alternatives include electric vehicle. This study aims to assess the readiness of electric mobility roll-out in Southeast Asia, especially from supporting policy perspective. It critically reviews the related policies from each ASEAN member states. Further, the PEST (Political, Economic, Social, Technological) framework is utilised to assess the readiness of such policies. Based on such analysis and identification of critical factors of electric mobility implementation, the study proposes policy recommendations.

Published: March 2022

AbstractThis paper examines the extent of climate change disclosure among energy firms operating in Africa and Asia, as well as the firm, country and global determinants of the disclosures. A quantitative approach was applied to evaluate an unbalanced panel data of 31 firms in 18 countries across Africa and Asia for 2015 to 2020. Data was collected from the GRI database and a composite index was constructed to measure the extent of climate change disclosure using “GRI 305:Emissions” indicators. The study used a regression model to find the nexus between climate change disclosure and its determinants. Comparatively, Asian energy firms disclose more than their African counterparts. The determinants of climate change disclosure are board size, board diversity, multinational status, profitability, cross-listing status, membership to the United Nations Global Compact and the Human Development Index of the countries within which firms operate. This study provides insights about the extent of GRI 305:Emissionsusage by energy firms in Africa and Asia. It also adds to the limited knowledge on climate change disclosure in Africa and Asia. With the recent COP26 conference in mind, this study extends knowledge on how businesses are taking action in line with the Agenda 2030 (specifically Sustainable Development Goal 13), the Paris Agreement and the Sendai Framework for Disaster Risk Reduction.

Authors: Azmi Rosalina , Maslahat Putri , Wahono Johannes W. 
Published: March 2022

Abstract
The causes of the carbon emissions is the one use of electrical energy. According to PLN (Perusahaan Listrik Negara), the electricity sector contributes 14% of carbon emissions of the total national emissions. The International Energy Agency (IEA) reported that the total of carbon dioxide (CO2) emissions reached 33.9 gigatons throughout 2020. A total of 13.5 gigatons of which came from electricity and heating, being the most compared to the other sources. Indonesia as the fourth most populous country in the world also contributes to carbon emissions from electricity use. The electricity consumption in Indonesia each year increases by an average of about 3.60% (from 2015-2020) and contributes to these carbon emissions. Indonesia with the largest potential sources of renewable energy (wind, solar power, geothermal and other sources), is expected to be able and develop and become a leader, especially in the Association of Southeast Asian Nations (ASEAN) Region. This paper will discuss the analysis of carbon footprint from electricity demand in Indonesia and renewable energy supply that can be used to reduce carbon emissions in dealing with climate change problems. The results of the analysis show that the carbon footprint of electricity usage per year on average is 5242.3 KgCO2. The Projection of Renewable Energy Growth in Indonesia in 2045 will reach 20711.67 megawatt. Estimates of net-zero carbon emissions in Indonesia conclude that Indonesia has not yet achieved net-zero carbon emissions in 2045.
Perceptions of Energy Resources Efficiency for Sustainable Development in the Developing Context of Nigeria: Implications for Enterprise Development in the Energy Sector
Authors: Raimi Lukman , Olowo Rabiu 
Published: March 2022

Abstract
Energy resources are indispensable to humans, animals, and plants. From the perspective of energy economics, energy efficiency has a high propensity to stimulate a development process that is environmentally, economically, and socially sustainable. Most developed countries are known to have attained energy efficiency, but the developing countries arguably still contend with energy inefficiency. In view of the foregoing, this study investigates the perceptions of energy resources efficiency for sustainable development in the developing context of Nigeria including implications for enterprise development in the energy sector. The study adopts a quantitative research method, a positivist research paradigm in order to generate fact-based information from energy users in the developing context. A sample of 400 respondents that comprised academics, professionals, business owners, policymakers, and activists working with the non-governmental organisations (NGOs) was selected, but 154 finally participated. The first finding reveals that Nigeria has eleven (11) energy resources, but the energy resource with the highest efficiency perception is fuel-wood and the least efficient is hydropower when measured in terms of stability, delivery system, reliability, resource mix, security, livelihood, and safety of energy products to the energy users. The second finding suggests that energy resources efficiency (EFF) exerts significant positive effect on the triple dimensions of sustainable development (ECS, SOS, and EVS) in the developing context of Nigeria, but the predictability is weak (42.6%, Adjusted R2). An indication that more rigorous study in required. The study contributes to the debates on energy resources efficiency and three pillars of sustainable development from the developing country context. In practical terms, the study supports and validates the X-Efficiency theory (XET) and the Resource Curse Theory (RCT).

Authors: Altomonte John Charles , Guinto Hannah Sofia 
Published: March 2022

Abstract
The Philippine energy sector remains plagued with issues of energy security, high electricity costs, and vulnerable grid infrastructure. This paper argues for the increased uptake of microgrids as a solution for these issues, using the Institutional Analysis and Development (IAD) Framework as a guide for microgrid policy. We begin this paper with an analysis of existing energy policies in the Philippines, highlighting a lacking integrated approach for energy security. The main discussion explores the IAD framework for microgrid development in the Philippines, identifying key barriers and dynamics among institutions and actors in the local energy sector. We then conclude with policy implications for adopting microgrids for the Philippine energy landscape.

Published: March 2022

Abstract
With goals in determining the effect of diluting the distillery wastewater (DWW) and of varying the amount of DWW and press mud (PM), anaerobic co-digestion study was carried out at mesophilic condition in a 2-L Erlenmeyer flask, with a working volume of 800 mL for Batch 1 and 1500 mL for Batch 2 experiments. For Batch 1, two different ratios of DWW and tap water, with 2:3 and 3:2, were used to assess the effect of dilution on the methane yield, where same volumetric amount of PM was added. For Batch 2, following ratio of PM and DWW were used: a) 1:0, b) 1:1, c) 1:1, d) 2:1, and e) 1:2. All samples had the same amount of inoculum, except that Batch 1 samples had bagasse. The parameters that were assessed after 42 days of digestion were: pH, COD, BOD, TSS, VS, Cu, Ca, Mg, Mn, TOC, TN, and methane yield. For the effect of dilution, a significant difference in the methane yield between samples with higher and lower dilution ratio was seen, and in the first batch, the optimal dilution ratio of DWW and H2O, with 3:2 gave higher methane yield of 78.23% (v/v). Meanwhile, optimal volumetric ratio of DWW and PM from the Batch 2 experiments, with value of 1:2, gave the highest methane yield of 79.43% (v/v).

Published: March 2022

Abstract
Natural disasters and human error factors can cause damage to buildings. Human error causes various issues, including inadequate craftsmanship in the mixing of building materials and preliminary structural design and specification. Inadequate knowledge of the building’s structure and the type of soil on which it stands is also one of the fault designs in construction. This study utilises a case study methodology divided into three sections: soil analysis, building analysis, and techniques for avoiding and repairing the research object. A literature review is essential to ascertain the type of soil and the proper footing to utilise when examining the soil. In the building analysis, it is necessary to determine the damage of the building and its repair. These steps demanded were to prevent further damage by adding structures to reinforce existing structures in load distribution. After determining that the structure is safe from further damage, the final step is to repair the walls, floor, and ceiling. These improvements are part of an effort to ensure the building’s long term sustainability. The final phase in home restoration is to decorate the interior to make the residents feel comfortable.

Abstract
In Purwakarta Regency there is a new area designated as a residential, commercial and industrial area, namely the Jatiluhur Estate Area. With the new area, it is necessary to know whether the availability of water can meet its water needs (water reliability) for the next 50 years. This research also carried out the water reliability mapping. Based on the analysis, both water availability with dependable discharge Q80% and Q90% overall and monthly, can fulfil the water needs of Jatiluhur Estate until 2070. However, with the regulation of water intake in the river, a ground tank is needed which takes into account the water loss of 19%, so that Q90% dependable discharge can fulfil the need while carrying out the regulation. From the results of monthly water reliability mapping, water reliability with Q80% and Q90% (overall) generate one color, four colors with Q80% (monthly), and three colors with Q90% (monthly). Whilst, the annual water reliability map generates one color for water reliability with Q80% and Q90% both overall and monthly.
Geofoam: A potential for Indonesia’s soil problem III – stabilizing retaining wall
Authors: Gunawan A 
Published: March 2022

Abstract
Increasing elevation of ground level is a common necessity in the construction world. For steep inclination, a retaining system is necessary to retain the soil embankment. When the embankment height is high, the required dimensions for the retaining wall can become humongous. This will result in excessive use of concrete, hence higher carbon footprint for the construction. To enable high retaining wall to be built without the support of huge retaining wall, light-weight backfill materials, such as geofoam can be used. In this paper, the use of geofoam to stabilize an eleven metre high retaining wall is presented. The eleven metre high retaining wall was filled with soil up to seven metre high, when cracks started to form in the retaining wall. Analysis show that failure would occur if the embankment continue to be filled. By replacing three metres out of the leftover four metres embankment with geofoam, the displacement of the retaining wall can be reduced from 2.1 m to 0.1 m.
