Authors: Sankaran Ganesh , S Venkatesan
Published: December 2022

The primary barrier to Electric Vehicle (EV) Purchase from an Indian customer’s point of view is the price of the vehicle. With the recent advancements in battery technologies and power electronics, the prices have come down dramatically and are expected to reduce even further. Many Original Equipment Manufacturers (OEMs) in India, preparing to include EVs in their portfolio will be an added advantage due to scale benefit. Therefore, it is necessary to study the impact of higher Initial purchase price, maintenance, and fuel cost of EVs compared to Internal combustion Engine (ICE) vehicles before product launches. Total Cost of Ownership (TCO) is a critical measurable from the customer’s point of view. The aim is to create customer awareness of TCO and encourage EV Purchases using quantifiable parameters. This paper studies and analyses the TCO between EV & ICE models using various cost elements, contribution factors, and alternatives like battery swapping using case studies.
Influence of Strategies in Injection on Shrinking Greenhouse Gas Emission in DiCI Engine with Tamarindus indica Biodiesel.
Authors: Ravikrishnan Ganesh Bharathi , Venkatesan S
Published: December 2022

Transportation cost is stepping the world into bio-feedstocks to power the Direct Injection Compression Ignition (DiCI) engines. Biodiesel makes a better alternative to diesel. In this research, tamarind seed biodiesel (TSB), is mixed 20% with diesel, with the injection pressure (IP) and timings (IT) modifications examining the engine’s performance, combustion, and emission aspects. The experimented IPs were 180 bar and 240 bar. The ITs were experimented with at 19° bTDC and 27° bTDC respectively. Modifying the IT to 27° bTDC, elongates the combustion period as well as the heat release rate (HRR) of the experiments which increases the emission of NOx in both the IPs (180 and 240 bar) compared with the diesel. Increase in NOx emissions parallelly projected the unburnt hydrocarbon emissions. Although, injecting the fuel 19° bTDC, shrank NOx emission owing to reduced HRR and peak in-cylinder pressures. However, increase in the IP to 240 bar is the predominant factor for the decrease in the emission of NOx and unburnt hydrocarbons, because of the increased fuel viscosity for the TSB. Increased atomization enhances the chemical delay which on other hand decreases the carbon monoxide. Hence fuel injected, 19° bTDC performed better with the reduced GHG emissions.

The need for less carbon content in fuel, as well as an increase in energy consumption, has paved the way for the development of alternative fuel for engines. Biodiesel is an environmentally friendly alternative to conventional fuel. Thermal barrier coating reduces heat transfer to the cooling system while the engine is idle and protects engine components from high thermal stresses. This paper investigates the blending of waste fish fry methyl esters in a single cylinder, four stroke DI diesel engine with a stellite-6 coated engine head. In this study, waste fish fry oil (WFFO) was transesterified with methanol and a NaOH catalyst. The methyl esters were obtained, and various test fuels were made (WFFO10, WFFO20, WFFO30) These blended samples were fired up in the DI diesel engine, and performance tests were conducted. Engine characteristics such as brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), and engine emissions were measured for the stellite6 coated cylinder head.

Authors: Mullai Sudaroli B. , Babu S. Sunil , Kumar S.
Published: December 2022

Methanol oxidation at the cathode catalyst layer is affected by crossing methanol through the membrane, resulting in a mixed potential. A Methanol crossover results in a mixed potential of 0.2V. Methanol concentrations regulate current density, which affects cell performance. When methanol is recirculated from the methanol tank, it is heated to cell temperature. The model is used to calculate the best operating parameters and the amount of oxygen consumed during methanol oxidation. Experiments to anticipate cathode potential loss owing to methanol crossover have been carried out. By using pure oxygen as an oxidant, the potential loss can be determined. The peak power density for the oxygen reduction reaction has risen from 16 mW/cm2 to 28 mW/cm2. The fuel for the cell is hydrogen and methanol. Throughout the cell’s performance, there is a possible loss of 0.2 V. When the concentration of methanol is 1 M, the peak power density is 10 mW/cm2. When the cell is run with hydrogen, the peak power density rises to 60 mW/cm2. The higher the methanol content, the greater the fuel and oxygen loss.

Published: December 2022

An Electro Static Precipitator is a filtration device that removes airborne particles like dust and ash from polluted air using principles of induced electric charges. While electrostatic precipitators are used in all major large scale industries, their use in small scale industries is limited. This is largely because small-scale manufacturers have the lack of awareness and the unavailability of equipment for pollution control in small scale industrial standards. This paper is intended to design and construct a scaled down and economized Electrostatic Precipitator which is controlled by a smoke detector circuit. This can be installed and utilized in small scale industries as an air pollution control unit. Design procedures of a scaled down precipitator chamber with a high voltage power supply and smoke detector circuit are presented in this article. These procedures are well illustrated in a stepwise manner and contain several statistical data and expressions required for the construction of the devices. A comparison of various topologies of various units of ESPs is made and the most appropriate selection for the scaled down model is proposed.
Reflecting on REDD+: Challenges Towards Indonesia’s Carbon Pricing
Authors: Dirgantara Pradipta
Published: December 2022

Indonesia, as one of many countries committed to implementing climate action frameworks, sees the need to develop solid carbon pricing regulations and expand the scope using its REDD+ (Reducing Emission from Deforestation and Forest Degradation Plus) experience. As a result-based payment for carbon trading, REDD+ can be a beneficial learning lesson for it. Prior to the United Nations Climate Change Conference 26 (COP), Indonesia demonstrated its political resolve to advance its climate policy by issuing a regulation on carbon pricing through Presidential Regulation No. 98/2021. Indonesia’s involvement in REDD+ has resulted in strong foundation accomplishments for carbon pricing implementation in terms of institutionalization, technicalities, and socioeconomic outcomes. However, not all REDD+ projects in Indonesia achieve the desired results. This paper aims to reflect on REDD+ as a lesson learned to identify the challenges towards Indonesia’s carbon pricing. A literature review and comparative study of carbon pricing implementation in Brazil, Canada, China, Colombia, and New Zealand were used to support this paper. This paper highlights several potential challenges to carbon pricing implementation in Indonesia such as determining the right instruments, strengthening government’s political will, transparency and public involvement, distribution of carbon price choices for subnational capacities, and the multi-nature of carbon pricing.

Published: December 2022

Most countries mitigate climate alter impacts by deploying renewable energy to decarbonize their energy system. One of the emerging renewable energy options is the integration of floating photovoltaic (FPV) and hydropower. The FPV has higher efficiency and helps to reduce evaporation and offset hydropower production during the dry season. Conversely, hydropower can overcome intermittent solar production due to its flexibility. Our study aims to estimate the energy potentials from FPV plants and hydropower integrations in Indonesia. As result, the country has 5,807 potential reservoirs for FPV and 26 hydropower plants with a reservoir area with a potential utilization of more than 1 MW. Those sites are suitable for 3 GW floating power plants and 2.8 GW hydropower. And those sites can reduce CO2 emissions by 2,911,197 tonnes per year.

Published: December 2022

Climate change is one of the most challenging threats of the Anthropocene epoch in the 21st century. Various researches have given close attention on climate change in Indonesia. However, there is lack of research which investigate the sustainability of climate change issue among women’s non-governmental organizations (women’s NGOs) in Indonesia. This paper fills the gap. This is qualitative research which gathered the voices of the five women’s NGOs in urban area of Jakarta and Bogor in 2021. This paper reveals the great potential of the sustainability of climate change issues to be carried out by the women’s NGOs in their works, as can be seen from their perspectives and programs though with different degree of focus and commitment. Their similar concern on climate change is due to the believe that climate change issues closely related to women’s lives and livelihoods, as well as, identified women as important actor in developing adaptation and solutions to climate change impacts. Even more interesting, they encouraged to increase men’s gender awareness to give more room for women’s voices in climate change decision making to deliver greater results for society.

Authors: Kurniawan V R B , Wahyudi A , Susanti D A
Published: December 2022

It is crucial to assess risks in projects as considering many factors with a high degree of uncertainty for project success. Although past studies were carried out on risk management in various projects, there are still wider opportunities to develop risk management integrating between a traditional risk management and a multi-criteria decision-making (MCDM) approach. Further, it involves multiple factors as well as decision makers (DMs) that may clearly represent the real situation. Accordingly, this study aims to develop a risk management model combined with the analytic hierarchy process (AHP) demonstrated in an Indonesian highway measurement project. There are five DMs invited to identify the 45 risk factors categorized into nine groups. Then, the AHP method was employed to calculate the weight of the risk groups before a traditional risk assessment was utilized to obtain the risk scores. With the Pareto chart, the result indicated that there were 23 critical risks including the project and measurement groups and the external risks such as natural disaster, political issues, and socio-cultural conflicts that should be seriously concerned. For a further study, it is strongly encouraged to analyze the uncontrollable external factors bringing significant impact on project particularly in developing countries.

Published: December 2022

The improvements of resolution and physical parameterization in the GCMs from Coupled Model Intercomparison Project Phase 5 (CMIP5) to Phase 6 (CMIP6) do not always guarantee the better representation of climate in several regions. The Maritime Continent (MC) region is influenced by dominant modes of climate phenomena such as the Madden Julian Oscillation (MJO), Indian Ocean Dipole (IOD), and El Niño-Southern Oscillation (ENSO). However, the representation of those phenomena from CMIP5 to CMIP6 models over MC has not been assessed yet. This study evaluates the signature of those phenomena on daily precipitation data of twelve models from each CMIP5 and CMIP6 against ERA-5 (as a reference) in the historical period (1981-2005) over MC. We perform Multiple Linear Regression (MLR) to assess the spatial signatures on daily precipitation anomalies and quantify the spatial similarity between models and reference using Cosine Similarity (CS). Then, we rank the CS values to obtain the best model. Result shows that only half of 12 models in CMIP6 improve from the models in CMIP5. Overall, MIROC5 (CMIP5) is the best model in representing the signature of those phenomena. Therefore, this study recommends the best models for climate change projection and adaptation strategy over the MC.
Fragmented Agencies in Public Sector: An Obstruction to Indonesia’s Climate Policy Implementation

Published: December 2022

Member states of the United Nations Framework on Climate Change (UNFCCC) are urged to limit its emission in order to maintain global temperature to 1.5 degrees Celsius that is textualised in the Glasgow Climate pact. In order to implement the mandate, Indonesia introduced several policies at national level. However, emerging issues in the public sector challenges the implementation of climate policy: fragmented agencies. This research attempts to address two questions; How fragmenting agencies impacts the implementation of climate policies? How can the implementation be possible amidst the emergence of fragmented agencies? This research utilises normative-empirical methods, where it would normatively analyse environmental policy agenda problems in selected ministries as public sector actors, while it would empirically examine the impact on the issue. This research shows that the issue of fragmented agencies in Indonesia has become the main obstacle in implementing climate policies due to the unsynchronized sectoral policy with the current climate policies in each ministry, where such fragmentation then obstructs good environmental governance. Furthermore, the implementation of Indonesia’s environmental and climate policies would not be optimally implemented if the aforementioned issue cannot be resolved through each ministries agenda restructuration. Another recommendation is to utilise the Penta Helix method in optimising climate policy implementation by multisectoral cooperation in climate policy.

Published: December 2022

Sugar demand in Indonesia is still increasing although its productivity remains low due to several constraints. Water scarcity also plays significant role on decreasing sugarcane production in Indonesia. Improved methods are strongly required to be applied by farmers as climate-smart strategies, for instance drip irrigation and organic mulching. AquaCrop is a modelling software which useful to simulate water balance and crop yield in corresponding to certain field managements. This study aimed to compare conventional methods i.e. rainfed (Scenario 1) and furrow irrigation (Scenario 2) combined by no mulching application to improved methods i.e. drip irrigation (Scenario 3) combined by organic mulching. Results shows that irrigation water requirement of drip irrigation are lower than furrow irrigation. Both evaporation and runoff of improved method are also considerably higher than other scenarios. Rainfed and furrow irrigation display similar water content by soil depth that lower than improved method. Crop yield on drip irrigation was 8% higher than furrow irrigation. Rainfed sugarcane presents lowest crop yield due to water stress. Improved method has 12-20% higher water productivity than conventional methods. Hence, implementation of drip irrigation and organic mulching can increase crop productivity as well as reduce water requirement in order to respond climate change.

Published: December 2022

PM2.5 is a respirable fine particle with harmful effects. PM2.5 prediction research plays a role to contribute scientific recommendations in actions for controlling air pollution. Nowadays, PM2.5 prediction using deep learning is the most chosen since it is an efficient and cost-effective method for air quality modeling. As a subset of deep learning, LSTM is strong in remembering past experiences and able to identify highly complex relationships of sequential data. LSTM has higher accuracy in time series prediction compared to other deep neural network models. On the other hand hybrid CNN-LSTM, a method that can produce good predictive models since CNN’s ability to extract spatial-temporal features might collaborate with LSTM, it is possible to identify stationary and non-stationary data. Meteorological parameters and other gaseous pollutants affect the concentration of PM2.5 proven by correlation analysis results. Therefore, it is appropriate to use as input for air quality modeling using either LSTM or the hybrid CNN-LSTM method.

Published: December 2022

The development of dams or reservoirs requires continuous attention. The dynamics of rain as the primary natural resource and the water utilization may change from the design. Climate change is thought to have caused changes in reservoir inflow patterns where the patterns may change throughout the service life of the reservoir. The way of the utilization of catchment areas and reservoir inundation is also very dynamic, along with the dynamics of water demand which is generally aimed at obtaining better human welfare. At the same time, such activities may affect the quality of the reservoir waters, followed by disturbances in the water utilization for various purposes. This paper presents the results of evaluating the carrying capacity of the reservoir environment based on the data obtained from reservoir sedimentation and water monitoring of Kedungombo Reservoir. The adopted method of the environmental carrying capacity of the Kedungombo Reservoir considers the four environment-related carrying capacities, i.e., reservoir sedimentation, water utilization, recreation, and aquaculture. The term overall carrying capacity is introduced, adopting three approximations of weighting factor α of the four parameters. The analysis results show a promising method to evaluate the reservoir environment carrying capacity that could be dynamics during its service life.

The Inter-Governmental Panel on Climate Change (IPCC) states that climate change is caused by increasing global warming as a result of human activities in various sectors of life, including the problem of waste. Lifestyle, lack of public awareness in controlling the waste is one of the important keys in increasing global warming. The study aims to find out the extent of adolescents’ understanding related to waste, waste management, and low-waste lifestyle. It was also to know the relationship between waste education and students’ awareness in handling waste in the surrounding environment. The data was obtained through online instruments distributed to students, the observation and other supporting media. The research employed a quantitative approach with quantitative descriptive analysis techniques using percentages.

The results of the data analysis showed that the level of students’ knowledge related to waste, waste control and low-waste lifestyle was in the good category, which reached an average of 83% correct answers. However, it was not in line with the students’ habits in minimizing food waste and plastic waste where 29.4% chose to throw away and 20.6% chose to burn. This was in line with the fact that there were still 14.6% of students who had not received education related to waste. It can be the basis for improving waste processing education in the educational environment as an effort to overcome climate change.

Published: December 2022

Today, we often hear or even discuss about climate change or in a universal language known as “Climate Change”. Climate change cannot be underestimated because although it is a physical change, it can damage the development results of various sectors that have been achieved and hinder the achievement of Indonesia’s SDGs. Solving the issue of climate change also cannot be solved by just one scientific discipline but requires multidisciplinary collaboration. This literature research reviews climate change in the midst of Indonesia’s SDGs- based development from various multidisciplinary perspectives while at the same time looking for opportunities for adoption and mitigation in the midst of a mud puddleof climate change threat. The results of this research suggest that scientific perspectives and the interests of Agribusiness, Higher Education, Public Health and Socio-culture are considered factors in implementing the SDGs program especially climate change, including adaptation and mitigation. Because if only focus on one perspective, it will be very difficult to accommodate the sustainable development of the SDGs in a pluralistic society. The role of a multidisciplinary perspective in this research is very influential in the adaptation and mitigationof climate change phenomena in the process of implementing the SDGs sustainable development. The solutions offered by each perspective can go hand in hand and support the resilience of the Indonesian nation and the world in the SDGs sustainable development process, including dealing with the phenomenon of Climate Change.

This research was conducted in several stages. The first was to make household waste liquid fertilizer with pumakkal formula P1 (3 bacterial isolates), P2 (6 bacterial isolates), P3 (9 bacterial isolates), P4 (12 bacterial isolates), P5 (15 bacterial isolates). The second was the test quality of household waste liquid fertilizers. The results showed the levels of NPK have quality standards of 2-6% with grades N (0,337), P (1,755), and K (3,818) at the highest treatment, and the values of N, P, K meet SNI. The C-Organic levels have a quality standard (minimum 10) with the value of 15,706 in the P5 treatment, and thus C-Organic exceeds SNI. The ratio level of C/N has a quality standard (≤25) with a value of 93,191 at the smallest P5 treatment compared to other treatments resulting in the ratio of C/N exceeding SNI. The pH has a quality standard (4-9) with a value of 6,176 on the P5 treatment, so the pH has met the SNI.

Rice is still the main food source for Indonesian people. The need for rice is increasing in line with the increasing of the population. On the other hand, the area of intensive rice fields is decreasing due to land conversion to non-agriculture. For this reason, there is a need to optimize the dry land in order to meet the domestic food needs. One aspect that really determines the success of rice production in dry land is the use of adaptive varieties such as local varieties. The Sigi Regency has large and varied collections of local upland rice germ plasm. The purpose of the study is to determine the presence of local upland rice and its morphological and agronomic characters in Sigi Regency, Central Sulawesi Province. The research uses survey methods and field observations of local upland rice plants. The survey was conducted in March 2020 and located in Pipikoro Sub-District, Sigi Regency, Central Sulawesi. The exploration results found 6 (six) upland rice accessions, namely Hiwangu, Rato, Topada, Kanantiti, Tingkaloko and Pulu lana. The six varieties have various characteristics, ranging from stems, leaves, panicles, unhulled rice and broken rice. Of the six accessions, two accessions are sticky rice.

Indonesia is one of the most populated countries in Southeast Asia, and this study attempts to identify the important elements that influence the maturity of Municipal Solid Waste Management (MSWM) in Indonesia. To assess previous studies undertaken in the SEA relevant to the creation of Solid Waste Management, a Systematic Literature Review (SLR) was conducted. A qualitative method was used to investigate the trends and patterns of MSWM by doing a literature review and assessing the news broadcasted on the country’s most popular website. The findings suggest that, first and foremost, excellent government policy can only work if it is supported by good implementation. Second, the existing solid waste management model does not include the most significant aspects as a tool. As a result, a suggested model of Solid Waste Management may assist the Indonesian government in managing it in a sustainable manner.

Indonesia’s climate change is frequently caused by vulnerable environmental management problems. Madura and its people have a lot of knowledge and innovation that they used to sustain themselves in the face of environmental issues. They lived with indigenous knowledge as a critical strategy to survive the Environmental issues. This study deals with how the Madurese survive and manage an environment that often lacks water due to extended droughts. Sustainable environmental management in the Madurese community is related to rituals to interact with nature. They have performed the Ojhung ritual regularly as an effort to balance the environment. They believe that nature and humans are closely related and inseparable. Therefore, in this study, the theory of Ecocriticism is used in understanding environmental management by the Madurese community through their indigenous knowledge. This study used a qualitative approach as the research method. Data were collected through in-depth interviews with related expert sources and literature review. The results of this study indicate the community believes that the environment will get its balance if humans wisely manage the environment by maintaining their indigenous knowledge.

The algebraic cobordism spectraMSL\mathbf {MSL}andMSp\mathbf {MSp}are constructed. They are commutative monoids in the category of symmetricT∧2T^{\wedge 2}-spectra. The spectrumMSp\mathbf {MSp}comes with a natural symplectic orientation given either by a tautological Thom classthMSp∈MSp4,2(MSp2)th^{\mathbf {MSp}} \in \mathbf {MSp}^{4,2}(\mathbf {MSp}_2), or a tautological Borel classb1MSp∈MSp4,2(HP∞)b_{1}^{\mathbf {MSp}} \in \mathbf {MSp}^{4,2}(HP^{\infty }), or any of six other equivalent structures. For a commutative monoidEEin the categorySH(S){SH}(S), it is proved that the assignmentφ↦φ(thMSp)\varphi \mapsto \varphi (th^{\mathbf {MSp}})identifies the set of homomorphisms of monoidsφ:MSp→E\varphi \colon \mathbf {MSp}\to Ein the motivic stable homotopy categorySH(S)SH(S)with the set of tautological Thom elements of symplectic orientations ofEE. A weaker universality result is obtained forMSL\mathbf {MSL}and special linear orientations. The universality ofMSp\mathbf {MSp}has been used by the authors to prove a Conner–Floyed type theorem. The weak universality ofMSL\mathbf {MSL}has been used by A. Ananyevskiy to prove another version of the Conner–Floyed type theorem.
Vancomycin AUC values estimated with trough-only data: Accuracy in an adult academic medical center population

Published: December 2022

Purpose

Vancomycin area under the concentration-time curve (AUC) can be calculated using steady-state serum peak and trough concentrations; however, compared to traditional trough-only monitoring, this approach requires an additional blood sample. Recently published data demonstrated vancomycin AUC estimations using trough-only data with a volume of distribution (Vd) model incorporating age and actual body weight were reasonably accurate and precise in a veteran population. This study sought to extend these methods to a Mayo Clinic adult population.

Methods

A retrospective, observational cohort of adult patients with documented steady-state vancomycin peak and trough concentrations was evaluated. Vancomycin AUCs were estimated using trough-only data, and 4 Vd models were assessed for accuracy and precision. Estimated AUCs were compared to AUCs calculated using 1-compartment intermittent infusion equations and steady-state peak and trough (“peak-trough”) data.

Results

The study population (N = 95) was 46% female, with a median age of 59 years and a median weight of 97 kg. Using the VancoPK equation Vd = 0.29 (age in y) + 0.33 (actual weight in kg) + 11, the mean peak-trough and estimated trough-only AUC were 533 and 534, respectively, with a correlation of 0.936. The root mean square error was 47.7, meaning about 95% of AUCs were within 95 mg · h/L of peak-trough AUCs.

Conclusions

Accuracy and precision of Vancomycin AUC estimations using trough-only data and the described Vd model were demonstrated in a Mayo Clinic cohort. Targeting an estimated AUC of 500 mg · h/L using the VancoPK model would likely result in an actual AUC within 400 to 600 mg · h/L.
