Published: December 2022

Abstract
Solar drying is useful in several residential, commercial and industrial applications. Proper dryer design, operation and maintenance are essential for enhancing the dryer performance and better quality of the dried product. Solar dryer is beneficial as it protects the product from adverse climatic conditions and quickly economically dry the product. The dryer design has undergone significant shapes, dimensions, and storage features leading to better reliability. Researchers worldwide have reported higher energetic and exergetic performance through advanced design, measurement, and control features. Conventional dryer’s efficiency deterioration is attributed to the lack of proper material selection and computational fluid flow techniques. Traditional dryer designs have focused on product drying rate while advanced sustainable solar dryer designs increased solar thermal utilization in a limited area with locally available materials based on fluid flow conditions suitable to the microclimatic conditions. Analysis using computational fluid dynamics (CFD) software has assisted in refining dryer designs to be compact with the complex flow and quick product drying features. The present paper tracks developments in solar dryer designs for different dryer classifications. Recommendations for energy-efficient design and measures for improvement in existing dryers are also discussed.

Published: December 2022

Abstract
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.

Published: December 2022

Abstract
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.

Published: December 2022

AbstractThe 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.

A Study on Cathode Potential of DMFC
Authors: Mullai Sudaroli B. , Babu S. Sunil , Kumar S. 
Published: December 2022

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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.

Published: December 2022

Abstract
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.
