The activated carbon (AC) electrodes were prepared by a two-step microwave-induced CO2 activation of OPS using bed temperature as control parameter. The electrochemical properties of the AC electrodes were investigated at room temperature by cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS) in 1 M H2SO4. The morphology, textural and chemical composition of the AC electrodes were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption isotherm and X-ray diffraction (XRD). The specific surface area (SBET), the total pore volume (Vt) and the micropore volume (Vμ) were found to increase with increase in both bed temperature and activation time with AC900-40 having the highest BET surface area of 574.37 m g, total pore volume of 0.124 cm g and micropore volume of 0.116 cm g. However, activation time was observed to have more profound effect as indicated by the values for AC800-40 being higher than that of AC900-20. The results of the electrochemical characterization show that the AC electrodes exhibit specific capacitance, power density and energy density of 134.68 F g, 225 W kg and 4.68 Wh Kg, respectively. Thus, the results indicated that using bed temperature as control parameter in microwave heating is a promising route to producing AC electrode with excellent performance.
以床层温度为控制参数，采用微波诱导CO2活化两步法制备了活性炭(AC)电极。采用循环伏安法(CV)、恒流充放电法(GCD)和电化学阻抗法(EIS)研究了室温下交流电极在1 M H2SO4中的电化学性能。采用扫描电镜(SEM)、透射电镜(TEM)、N2吸附等温线和x射线衍射(XRD)对电极的形貌、结构和化学成分进行了表征。比表面积(SBET)、总孔体积(Vt)和微孔体积(Vμ)随床层温度和活化时间的增加而增大，其中AC900-40的比表面积(SBET)、总孔体积(Vt)和微孔体积(Vμ)最大，分别为574.37 m g、0.124 cm g和0.116 cm g，而活化时间对AC800-40的影响更为深远，AC800-40的比表面积(SBET)高于AC900-20。电化学表征结果表明，该交流电极的比电容、功率密度和能量密度分别为134.68 F g、225 W kg和4.68 Wh kg。结果表明，在微波加热过程中，以床层温度为控制参数是制备性能优良的交流电极的有效途径。

This paper examines the implementation of Customer Relationship Management (CRM) and the role of social media in small and medium enterprises (SMEs). Understanding these phenomena is very critical since SMEs have used social media to interact with their customers, however little researches has been conducted so far that linked social media and CRM capabilities. This study applied a sequential mixed method, including interview with informants, and surveys to a total of 206 respondents in the SMEs Gapura Digital forum. The collected data was checked using the structural equation modeling. This study clarifies that social media is a mandatory tool to connect with customer needs. In which the environmental context has a positive impact of 24% therefore, this study suggested an application of CRM in SMEs which is strongly motivated by the environmental context, such as a forum or group of SMEs that enable them to coordinate and exchange information easier among themselves. The study of this phenomenon is expected to contribute to the development of science, especially CRM and SMEs.

RCAS (Rear-end Collision Avoidance Systems) is one of the safety features in autonomous cars that can determine what kind of movement that a car installed with the RCAS system should perform to avoid any crashes with another car/object in front of it. This camera-based RCAS uses a Pixy CMUCAM5 camera to measure the distance of a leading car. The measured distance used as the input of a Fuzzy Logic Algorithm will determine the speed and steering angle of the car. This system is applied to a small toy car with an Active Steering Assist to execute the calculated movement that should be performed by the car. The use of this system is proven to improve the level of the safety of the car by successfully avoiding possible collisions.

Islamic rural bank is a type of banks in Indonesia with a high level of non-performing financing. It is an important issue because will ultimately affect profit as the main goal. This study aims to examine the factors that affect nonperforming financing (NPF) at Islamic rural banks in Indonesia, those are economic conditions consisting of gross domestic product (GDP), Bank Indonesia-rate (BI-rate), and inflation, and banking. The policy consists of financial to deposit ratio (FDR) and capital adequacy ratio (CAR), and their impact on profitability. The population of this study is all Islamic rural banks in Indonesia with a sample of banks operating during 2014-2018. Panel data is analyzed using the PLS-SEM tool. The result shows that inflation as well as FDR, have a positive effect on NPF, while GDP, BI-rate, and CAR have no effect on NPF. Results also indicate that NPF has a negative effect on profitability. These results can be a consideration for bank management to control financial and pay attention to rising inflation, to overcome non-performing financing, because these two factors can be signals in control and managing to develop the profit.

The banking sector is starting to become a concern for research because it plays a major role in addressing social and environmental challenges and can positively influence society through the implementation of CSR. This study aims to determine the differences in CSR (disclosure) between Islamic banks and conventional banks, the effect of capital structure (capital adequacy ratio / CAR) and leverage (debt to asset ratio / DAR) on CSR, and the effect of CSR on profitability (return on assets). The operationalization of the CSR variable refers to the GRI (Global Reporting Initiative) 4.0 and ISR (Islamic Social Reporting) indicators. Panel data were analyzed using PLS-SEM and SPSS 24 tools. The results showed that there was no difference in CSR disclosure between conventional Islamic banks.

This paper aims to describe research findings on the application of the Most Significant Change as a means of evaluating student learning outcomes in the Pancasila Education course. Especially changes in behavior related to the Five Fundamental Principles (Pancasila) values during the e-learning teaching period. Students need to be aware that every decision taken is related to themselves and has implications for their social life and environment. The research described in this paper uses a descriptive qualitative approach. Data collection used the Most Significant Change (MSC) method developed in 1995 by Davies and popularized by Davies and Dart. MSC is a participatory, qualitative data collection and analysis method which is story-based. The process involved collecting stories from sixty (60) students as participants. Forty-five stories were shared by participants to identify the Most Significant Change to students' behavior development. Mostly about the impact of changes in learning patterns from a face-to-face approach and practice in classrooms at higher education locations, which change into online lectures using various applications. There are many characters based on students' Pancasila values during learning from home, including strengthening prayer obligation, living independently, having enthusiasm, building unity, cooperation, helping each other, being creative, and never giving up. The challenge of availability of stable internet access and good quality computers much supports student learning outcomes. All parties highly support providing an internet quota from the government through the institution to provide education. Learning from home for the Pancasila Education course can be concluded as quite successful, although some obstacles are still implementing.
