Indonesia still has a high dependence on fossil energy. This can be seen through how the use of fossil energy still dominates the energy needs in Indonesia. Most of this fossil energy comes from oil sources. However, the increasing use of energy and the reduction in fossil energy reserves has made Indonesia need to use renewable energy. This needs to be done to achieve energy security in Indonesia. This research will be carried out to see how the conceptual framework and policies regarding energy security in transportation in Indonesia through electrical energy can support energy security in Indonesia. This research will be carried out using a literature study approach. According to the findings of this study, there are multiple concepts in energy security, including the availability of existing energy resources that can meet energy demand, existing support in facilities such as distribution, transportation, and production division that can meet energy consumption needs, and the minimal negative impact of energy production and consumption on human health and the surrounding environment.

“…Coal is the most abundant fossil fuel on earth, providing more than a third of global electricity generation and having a major influence on the world economy [1]. The coal mined in Brazil has a high sulfur content in its composition, requiring the processing of raw coal from mines (Run of Mine -ROM) to meet the specifications required by thermoelectric plants.…”

Processing of pyrite derived from coal mining waste by density separation technique using lithium heteropolytungstate (LST)

Pyrite (FeS 2 ) is one of the main tailings derived from coal mining. When processed, pyrite has several applications with high value-added, in contrast, if improperly discarded, it causes major environmental impacts, like the acid mine drainage. For those reasons, the seeking for beneficiation techniques of Pyrite has been the target of numerous studies. One of the most employed techniques is the separation by density using heavy liquids, like bromoform, as a separation medium. In the present work, we propose the use of lithium heteropolytungstate (LST), a non-halogenated and non-toxic solution, as an alternative in the separation by density method. For the experiments, raw pyrite samples were collected from the tailings of coal extraction from a mining company in Santa Catarina, Brazil. After the separation process, the samples before and after the beneficiation were characterized by XRD, FTIR, and XRF techniques. The results revealed that the separation technique used in this work led to a significant increase in the concentration of pyrite, going from less than 10% in the raw sample and reaching almost 80% after processing. This impressive result reveals that LST represents a promising alternative for separating pyrite by density techniques, showing much greater effectiveness than other heavy liquids used in the literature, in addition to being environmentally friendly.

“…India is no exception to that and is the second-largest importer of fuel in the world. Of the total fuel requirement, the imported fuel itself accounts for half the total fuel, and cooking consumes a significant amount [1]. Under these circumstances, if energy-efficient cooking technologies are not developed, fossil fuel depletion will be severe.…”

The present study is to conduct a Techno-economic Assessment of a 5-7 kW Porous Radiant Burner (PRB) – based LPG cook-stove operating in eateries and restaurants. Process flow study has been performed primarily to understand the technological process involved in the PRB and also to estimate the cost of manufacturing. The cost estimation has been done considering direct costs such as material costs and labor costs, and indirect costs such as factory costs, works costs and administration costs. Sensitivity analysis has been performed considering the production capacity of 50, 250 and 500 cook-stoves each day. An economic feasibility study of PRB cook-stoves has been done by estimating the Pay Back Period, Net Present Value and Internal Rate of Return. For a manufacturing capacity of 250 cook-stoves per day, PRB yields a 51.4% return on the investment with a payback period of 0.68 years. Adopting PRB-based cook-stoves in small, medium and large-scale eateries results in an annual saving of Rs. 77500, Rs. 235000 and Rs. 1170000, indicating that PRB-based cook-stoves are undoubtedly economically viable.
