<p><strong>Aims</strong><strong>:</strong> This study aimed to increase the utilization of biomass-derived from the waste of coconut and peanut shells by making them as briquettes, as an alternative to fuel. The scarcity of petroleum because of its increasingly limited existence encourages all parties to take part in the development and discovery of new alternative energies. This is expected to overcome one of the most important of the many problems facing this country. The method used in this research is to start with a literature study of materials from various sources about the benefits and manufacturing of briquettes from biomass waste as an alternative energy source to be further tested for quality.  This involves a heat test, water content test, ash content test and determination of the flying matter. <strong>Results</strong><strong>:</strong> The test results showed that natural gas emissions were below threshold, namely 0-30 ppm CO, 0-3.6 ppm H<sub>2</sub>S, and undetectable NO<sub>x</sub>. After evaluation, the results showed that with the addition of 30% of the biomass, the ignition time was reduced and the remaining unburned briquettes or bottom ash was reduced by 68.68%. <strong>Conclusion, significance, and impact of study:</strong><strong> </strong>The results help the community and the parties involved related to appropriate bio briquettes technology. It also eventually becomes one of the solutions to assist the government in solving problems related to alternative fuels to petroleum.</p>

Abstract This research made three kinds of briquettes from various biomass waste, including alaban wood charcoal and rubber seed shells mixed with coal bottom ash and coal fly ash. The purpose of the study was to obtain the characteristics and quality of briquette combustion. Making briquettes is by drying, grinding, and sifting raw materials then mixed with adhesive, printing and drying. Briquettes were made with variations in composition and pressure and the particle size of the material passing through the 50 and 250 mesh sieves. Briquettes produced from alaban wood charcoal and coal bottom ash, or fly ash, obtained more bottom ash or fly ash composition characteristics. The moisture content and calorific value would be lower while the ash content was higher. While the initial ignition time, the combustion duration is getting longer, but the burning rate would decrease. Briquettes made from rubber seed shells and coal bottom ash obtained variations in composition and pressure that affect the characteristics and quality of combustion. The higher the rubber seed shell composition and pressure, the lower the water and ash content, but the calorific value increased.

These books are numbers 4 and 5, respectively, in the series "Studies in the Economic Development of India". The two books are interesting complements to one another, both being concerned with the analysis of projects within national plan formulation. However, they treat different sorts of problems and do so on very different levels. Marglin's Public Investment Criteria is a short treatise on the problems of cost-benefit analysis in an Indian type economy, i.e., a mixed economy in which the government accepts a large planning responsibility. The book, which is wholely theoretical, explains the many criteria needed for evaluation of projects. The work is aimed at beginning students and government officials with some training in economics. It is a clear and interesting "introduction to the special branch of economics that concerns itself with systematic analysis of investment alternatives from the point of view of a government".

The Impact

Based on the panel data of 277 cities between 2003 and 2017 and a unique city-level dataset of green patent applications, this study employs the difference-in-differences (DID) method to evaluate the effect of China’s carbon emission trading scheme (ETS) pilots on urban green innovation. The findings indicate that China’s ETS pilots have a positive impact on urban green innovation, and that impact is more significant for municipalities than for prefecture-level cities. Furthermore, the impact on different categories of urban green innovation is heterogeneous. More specifically, China’s ETS pilots have significantly spurred urban green innovation that is closely related to energy conservation and emission reduction, including alternative energy production, transportation, energy conservation and so forth. Moreover, the facilitating effect of China’s ETS pilots on urban green innovation suffers from a lagging effect, which began to show a significant positive effect in 2016. Overall, this paper identifies the effect of China’s ETS pilots on urban green innovation, and suggests that the government should consider the heterogeneity of urban green innovation when designing national ETS policies.

With the advancement of technology, digitalization, and the internet of things, large amounts of complex data are being produced daily. This vast quantity of various data produced at high speed is referred to as Big Data. The utilization of Big Data is being implemented with success in the private sector, yet the public sector seems to be falling behind despite the many potentials Big Data has already presented. In this regard, this paper explores ways in which the government can recognize the use of Big Data for official statistics. It begins by gathering and presenting Big Data-related initiatives and projects across the globe for various types and sources of Big Data implemented. Further, this paper discusses the opportunities, challenges, and risks associated with using Big Data, particularly in official statistics. This paper also aims to assess the current utilization of Big Data in the country through focus group discussions and key informant interviews. Based on desk review, discussions, and interviews, the paper then concludes with a proposed framework that provides ways in which Big Data may be utilized by the government to augment official statistics.

Charcoal and firewood fuel biomass utilization is thought to be the main cause of deforestation in Uganda. Moreover, the practice of utilizing charcoal and wood fuel in Uganda is said to impact the health of many women and children in the region. The goal of this study was to comprehensively analyze charcoal and wood fuel utilization processes in Uganda and sub-Saharan Africa and the environmental and socioeconomic dynamics and implications. The study equally intended to model out some possible improvements to wood fuel use while conserving natural forests. Both qualitative and qualitative approaches were used to study the charcoal and wood fuel energy situation in Uganda. The study collected field data (sample size: 199) which was subjected to descriptive analysis. The findings show that over 90% of households in Uganda and the sub- Saharan region use firewood and charcoal wood fuel, and that this fuel use creates social and environmental hazards. Our findings are also in agreement with numerous empirical studies showing that firewood and charcoal biomass are among the major causes of deforestation in Uganda and the sub-Saharan region. Ceteris paribus, we propose the adoption of Improved Eco-Stoves (ICE), which not only enable comprehensive combustion but also lessen the quantity of firewood used by more than 60%, together with policy decisions on the government of Uganda, given peoples willingness to take on alternative energy sources such as gas and electricity.
