Abstract
This paper presents an adaptive method for power management in smart shoes data transmission. Adaptive here means that the power for data transmission can be adjusted by selecting the shortest path. We use the Fuzzy Method to develop this adaptive system. Exchange of data between nodes scattered in smart and moving shoes with users can be set by Fuzzy placed on the sink. Sink collects data and sends it to the cloud. Based on our experiments on sports fields with several users with relaxed, brisk and running modes show very significant power savings compared to previous methods. The average energy efficiency can reach 35% better than the previous methods.

Abstract
Abstract. Photosupercapacitor is an integrated device for harvesting and storing of solar energy into electrical energy. Photosupercapacitor is constructed by solar cell (DSSC) and supercapacitor. In the solar cell part, one of the influential variables is the photoanode performance. The photoanode with ZnO layer play a role in light absorption, charge mobility, and wide band gap, which are influenced by crystal structure and nanoscale morphology. One of nanoscale morphology of ZnO is nanorods. This work is planned to investigate the effect of annealing temperature of seed layer ZnO to growth nanorods shape in photoanode of photosupercapacitor on its performance. The seed layer ZnO nanoparticle was deposited onto FTO substrate by a screen printing method. The ZnO nanorods was grown by soak FTO/ZnO in solution (Zinc nitrate, HMT, and DI water) under 100 C. The photosupercapacitor is constructed by DSSC and ZnO symmetric supercapacitor which integrated by using aluminum foil substrate. Characterization was done using XRD, SEM, UV-Vis, and I-V solar simulator for photosupercapacitor performance.

Abstract
Material research for harvesting energy is increasing in an effort to find alternative renewable energy devices. A lot of thermal energy wasted in everyday life. Research for various alternative high-capacitance supercapacitor materials continue to be encouraged. SrTiO3 shows a good electrical and dielectric properties, as well as defect induced structure. Modification of local structure using Pb dopant on the SrTi1-xPbxO3 was applied for exploring the scientific information and its potential applications intensively. Synthesis of SrTi1-xPbxO3 was prepared by solid-state reaction method. The powder was then calcined, pressed into pellet, and subsequently sintered at 860 C. Various fraction of lead (Pb) dopants were carried out in 0.00; 0.02; 0.04; 0.06; 0.08; 0.1 molar ratio. The structure, morphology, and thermoelectric properties of SrTi1-xPbxO3 composite powder were performed by using X-Ray Diffraction, SEM-EDX, and temperature induced conductivity. EDX data analysis revealed that the composition of the sample was in accordance with the composition designed. XRD data analysis with Cu-Ka wavelength indicated the single phase was identified and a slight change in lattice parameters was observed. Sixfold symmetry of the local octahedral structure also changed to a tetragonal structure after introducing the amount of Pb element. For investigating electrical properties of SrTi1-xPbxO3, I-V meter was applied. Furthermore, electrical conductivity and dielectric constant will be discussed in detail. Loading higher Pb fraction promoted the electrical conductivity measured at various temperatures. Increasing conductivity is one indicator that this system potentially enhanced electronic exchange of supercapacitor in SrTi1-xPbxO3 system.

Abstract
The development of energy storage devices encourage sustainability of research on basic materials of supercapacitor technology. SrTiO3 is oxide metal called as titanate alkali metal ATiO3 (A = Ba, Sr, Ca). This material shows an excellent dielectric constant, thus expected to be a potential as raw material of supercapacitor. In this work, boron was used as a dopant on SrTiO3 system. Synthesis SrTi1-xBxO3 was carried out using solid-state reaction method followed by sintering process in various molar ratio. By introducing boron, it was expected to modify its local structure and enhance the electrical properties. The microstructure of SrTi1-xBxO3 compound was identified by X-ray Diffraction with Cu-Ka. Based on XRD data analysis, a single phase of SrTi1-xBxO3 material was confirmed with a slight change in lattice parameters. Furthermore, SEM-EDX was used to observe the morphology and elemental composition of SrTi1-xBxO3. For investigating the electrical conductivity, I-V meter measurement was applied by inducing various temperature. Higher boron fraction in the compound raised the electrical conductivity, thus it will be performed as supercapacitor material.

Abstract
Batteries are an important component in terms of electricity. It is undeniable that the need for batteries is a primary need at this time. The greater the voltage needed, the more batteries needed to generate electricity. Ultra Step Up converter is a series of dc to dc that can increase the DC energy source. The Ultra Step Up converter has the advantage of being able to increase the voltage with a large enough gain so that the voltage output value is very large with a small input voltage. In this final project Ultra Step Up converter will be developed with constant voltage regulation using Fuzzy Logic Controller. The DC battery source is 48V as input from the converter which will produce an output voltage that exceeds the boost converter output voltage. The advantage of Ultra Step Up Converter is that it can increase the voltage higher than conventional converters such as Boost Converter, and has good efficiency. Based on the simulation results show that the output voltage has reached the expected value of 540V with the initial ripple not too high with a duty cycle of less than 50%. To keep the output voltage constant, the Sugeno type fuzzy logic controller is used.
