Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

In order to make the charging process of the battery easier, it needs to possess a design tool with suitable characteristics. One of the main characteristics of the battery is the State of Charge (SoC) or simply the battery capacity, which is calculated with the help of the initial voltage value. In this process, a 100Wp photovoltaic panel with 12V DC voltage is applied. The method used is experimental and simulation/modeling, and its purpose is to optimize the efficiency of the process of battery charging. Furthermore, the Arduino microcontroller, which functions are a detector during battery charging, was used to determine the current and voltage sensor controller circuit. The voltage and SoC on the battery are automatically monitored via the LCD and on the SD card using the data logger shield module. ICM algorithm used for modeling-simulation in this study is one of the MPPT type used by photovoltaic systems that work at optimum conditions, thereby producing maximum power. The results showed that the battery charging simulation increased by 0.05% every 30 minutes. Furthermore, the simulation validation using Matlab/Simulink is carried out with data following the prototype design, at an efficiency of 88.37%
The research of synthesis of impregnated TiO2 Ouw natural clay with the study of calcination temperature has been done. The calcination process was carried out at temperature variations of 200, 300, and 400 oC. Characterization of the structure was performed by using X-ray diffraction (XRD), scanning electron microscope (SEM) and infrared (IR) spectrophotometer. The result of characterization with XRD showed that the impregnated TiO2 clay at 200 oC has the highest crystallinity. Calcination at 300 oC resulted in the loss of a montmorillonite reflection peak, while calcination at 400 °C resulted in the loss of two montmorillonite reflections and a drastic decrease in intensity. The crystalline phase of TiO2 formed was a combination of the crystalline phases of rutile and anatase, with the rutile crystalline phase being more dominant. The SEM characterization results showed a more even distribution of TiO2 in calcined clay. Calcination at 200 oC resulted in a more even distribution of TiO2 than calcination at 300 oC and 400 oC temperatures
