“…This study found that H2 is supported or financial technology has a positive and significant influence on financial inclusion. The finding inline with the reserach conducted by (Shen, Hu, & Hueng, 2018), (Elghool et al, 2020), (Ajeil, Ibraheem, Azar, & Humaidi, 2020), and (Nande & Irman, 2021) which stated that financial technology products has an influence on financial inclusion. The rapid development of financial technology makes people having easy access on various financial technology products.…”

Someone who has appropriate knowledge toward financial literacy (well literate) will be faster to learn about how financial institution works. Unfortunately, the level of financial literacy in Indonesia is only reached 29 percent. However, the goventment target on financial literacy itself is reached up to 75 percennt. Since the knowledge on how to manage the personal budget is quite important, people need to know to overcome the financial problem that could be occur in the future endeavors. This research aim to identificate the level of influence financial literacy toward financial inclusion in Special Region of Yogyakarta, Indonesia as part of the impact by financial technology usage. This study was used quantitative apprach using 133 respondents in Special Region of Yogyakarta. The data were obtained from spreading the questionnaire and interviews with respondents. Data analysis in this study used multiple linear regression using SPSS ver. 22. The result of this study shows that only financial technology which supported to influence financial Inclusion.

“…Elghool et al [98] used the response surface methodology to determine the optimum geometry of the heat pipe heat sink to improve the performance of the thermo-electric generator. The results showed that the efficiency after the optimization was 3% respectively, which was improved by 36.7% compared to the previous results.…”

“…In the previous examples [ 27 , 33 , 34 , 35 ], fin dissipators in natural convection were used due to their simplicity and low cost. Nonetheless, in this case, heat exchangers based on phase change will be again used since they have demonstrated to be the most suitable ones for the cold side of the modules, leading to low thermal resistances without requiring auxiliary consumption [ 43 , 44 ]. Their mode of operation is similar to the hot side one, with cyclic vaporization and condensation of the internal fluid, although in this case heat is absorbed from the thermoelectric modules and released into the environment ( Figure 1 ).…”

Although there is an important lack of commercial thermoelectric applications mainly due to their low efficiency, there exist some cases in which thermoelectric generators are the best option thanks to their well-known advantages, such as reliability, lack of maintenance and scalability. In this sense, the present paper develops a novel thermoelectric application in order to supply power to volcanic monitoring stations, making them completely autonomous. These stations become indispensable in any volcano since they are able to predict eruptions. Nevertheless, they present energy supply difficulties due to the absence of power grid, the remote access, and the climatology. As a solution, this work has designed a new integral system composed of thermoelectric generators with high efficiency heat exchangers, and its associated electronics, developed thanks to Internet of Things (IoT) technologies. Thus, the heat emitted from volcanic fumaroles is transformed directly into electricity with thermoelectric generators with passive heat exchangers based on phase change, leading to a continuous generation without moving parts that powers different sensors, the information of which is emitted via LoRa. The viability of the solution has been demonstrated both at the laboratory and at a real volcano, Teide (Canary Islands, Spain), where a compact prototype has been installed in an 82 °C fumarole. The results obtained during more than eight months of operation prove the robustness and durability of the developed generator, which has been in operation without maintenance and under several kinds of meteorological conditions, leading to an average generation of 0.49 W and a continuous emission over more than 14 km.
